DESCRIPTION I I I I A NONvlOVEN w'EB FOR FASTENER FEMALE MEMBER I I TECHNICAL FIELD I The subject. invention generally relat·es. to a nom·10ven I ' I ' I web for use ·in connec'tion \·lith a fastening system such as a: receiving.component of a fastener. I 10 BACKGROUND ART Refastenable mechanical fastening systems can be used in a >~ide number· of applications. For example, such refastenable fastening systems can be used to connect one portion of a disposable absorbent article to another portion · 15 of the disposable absorbent article. In general, mechanical fastening systems contain a receiving component (e. g., a female component) and an engaging 1.: component (e. g., a male component) . In some mecha.nical fastening systems' the, engaging component contains a plurality 20 of hook elemepts, anct: the receiving component cqntains a plural.ity of loop elements. In a fas.tened state, the hook elements typically are entangled with the loop elements, thereby forming· a connection between the engaging and receiving components. 2 Nomwven l·mbs can be used as the receiving component. Typically, a nonwoven receiving component contains a plurality of polymeric fibers. Portions of-these fibers can be joined .together by fiber-to-fiber bonds to form a l·reb having .. 5 sufficient available u'ribonded fibers or imbonded portions of bonded fibers and 1·1eb integrity. The fiber-to-fiber bonds are typically . formed by fusing portions fibers together via, for ' ·example,: heat, pressure, o·r:·sound ( e.'g., ultrasonic) energy. ,. In some processes, a pair of heated calendering rolls 10 . can be used to create these fiber-to-fiber bonds. Typically, one of the calendering· rolls contains a plurality of protrus'ions which extend olltHard from its outer surface. A lr cons'tant force is generally applied to one of the-calendering ··rolls such that as the nom10ven 1·1eb passes bett-1een the 15 calendering rolls, the protrusions apply pressure to the 20 nomroven l•reb. In general, at the locat-ion of applied pressure, at least one fiber-to~fiber bond is created. SUMMARY The folloHing presents a simplified summary of the invention in order to provide a basic understanding of. some aspects of the invention. This summary is not an extensive .overvieH of the invention. It is intended to neither identify key or critical elements of the invention nor delineate the 3 . ;. I 'I scope of the inventio~. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude ·t·o the more detailed description that is presented later. .

The 10 nom1oven .1·/eb can be used as a receiving· component/member of ·a fastener. The rioni~oven Heb contains a composite fiber 'having ·crimps and containing first ·and second propylene polymers. The bonded portion contains zigzag unit patterns I I. that are disposed in a machine direction· at predetermined ·I intervals, the zigzag .unit patterns being continuous I I I substantially parallel with a cross machine direction.

DEFINITIONS As used herein, the terms "absorbent article" and 20 "article" refer to a wearable device that absorbs and/or contains liquid and, more specifically, refers to a device that is placed against or in proximity to the body of the wearer to absorb and contaiY) the various exudates discharged from the body. Suitable examples include diapers, trainiY)g pants, 7 I I refastenable pants, pull-on garments, ac\ult incontinenc': 'I . . . I products and feminine care products such as s·anitaJ;y napkins. . I Furthermore, the terms "absorbent a·rticle" and "article" I include a "disposable abso:i:bent article" Hhich is intended to 1 ' 5 be (jiscarded ·and not laundered or othen~lse restored after no ! more .than about ter\ us.es,. preferably qfter no more than about five . -. : ·. . : : ~ . ' ) . '. . . us.e. s. , and most p. referably after a single use (although certain •components may be· recycled, . reused, or composted) . , 1 ''Body-facin9u _and. "g.ci.rment-facing" refer reSpectively 10 to the relative loca•i:ion of an element or a surface of an element or group of elements. · "Body-fd.cir:g" implies the element or surface is nearer to the wearer during Hear than some other element or surface. "Garment-facing" implies the e·lement or surface is more remote from the l..rearer during vtear .15 than some other elemeht or surface (e. g .. , element or surface is .Proximate to the >Tearer's garments that may be \•Torn over the disposable absorbent article) . . . As. used herein, the t"'rm "bond lin~" refers to a· piurali ty of sites on a substrate Hhere the fibers of the substrate have 20 been fused together. The plurality of sites can be fused together to form the ''line .. u However, the term 11 line," as used herein, can also describe a series of discrete points or short . lines c;Losely spaced so. as to effectively approximate a line. Therefore, those skilled iri art Hill recognize that although 8 I I I i I I I i i I ' another element by affixing the element c;!Lrectly to the other ·element, and configurations •·1hereby an element is indirectly ' I ' I I secured to another element by affixin~ the element to a~ I intermediate member ( s) which in turn are affixed to the other ! I. I I 5 element. I I The term "longij:udinal" is used herein to refe·r to a I i direction Hhich is generally parallel to the longest edge of j ·an element except VThere other1'1ise no.ted. In the context of disposable absorbent ~rticl~s. a "longitudinal" direction 10 runs. substantially perpendicular from. a I·Jaist edge to an ' .. opposing Haist edge of the article and generally parallel to the maximum linear dimension of the article. Directions within ±.about 45 degrees of the longitudinal direction are considered to be "longitudinal." 15 The ·term "lateral" refers to.: a direction running generally perpendicular to and in the same plane as the 1 '';longitudinal" direction. In the context of disposable absorbent articles, a "la·teral"1 direction runs from one longitudinal edge of the article to an opposing longitudinal 20 edge of the article. Directions 1·1i thiri ± about 45 degrees of the lateral direction are considered to be "lateral." The terms ''machine direction" or \\MD" refer to a direction Hhich is generally parallel to the for1·1ard direction of a material, member, element, item, component, etc. through 10 I I ! i a process. For example, non;.;ovens are typically formed with a machine direction that.corresponds to the long or rolled direction of fabrication. The machine direction can also be i the primary direction of f·iber orientat.ion in the nomlcJVen. · i 5 - The ·terms "cross machine direction" or "CD" refer to a i I direction which is generally perpendicular to and in the same i plane as the machine direction. The t~rms "pant," "~r~ining p~nt,n "closed diaper," "pre-fastened diaper, If· anc;l ."pull-on diaper, H as us~d herein, . . . 10 refer to disposable' garments having a· ;~aist openi~g and leg t. ·I openings designed for infimt or adult \'l.earers. A pimt can be .i ' configured such that th~ pant has a closed waist and leg openings prior to being donned on the 1·1earer, or the pant can be configured such that the H.aist is closed and the leg open.ings . '15 formed H'h ile on the wearer. A pant may be preformed by any suitable'technique including, but not limited to, joining together portions of tli.e article using a refastenal!Jle fastening system. A pant I_Uay be preformed anyt·lhere along the 1· ' cir~umference of the aiticle (e.g., side fastened, front VTaist j I ~0 fastened, rear v.raist fastened).

Because the fiber-to-fiber bonds typically render the bonded areas unengageable by ')n engaging 10 component, bonding the nomwven 1·1eb completely can yield ,a L poorly performing recei vi fig component. Therefore, the protrusions extending oub1ard from t)Je outer surface of the calendering roll are typically spaced apart such that a particular bonding pattern is created in the nomroven. 15 It may be desirable to have large, open, unbonded areas to assure 'that wherever a hook from the engaging component is .placed an unbonded fiber or an tinbonded portion of a bonded fiber is available to engage the hook. However, a bond pattern 1 • • creating· large, open, unbonded areas can have reduced strength 20 in a cross machine direction because of the reduced number of fiber-to-fiber bonds in the unbonded areas. To compensate, some bond patterns can create fully enclosed areas e, g., fully bonded fibers surrounding unbonded fibers. However, a bond pattern VJhich creates fully bonded fibers surroundi;ng unbonded 12 I I I I ·' I. ., i I I i i I I I I fibers can reduce the; likelihood that a hook from an engaging I component 1·1ill find an unbonded fiber with 1·1hich it can engage. Addi tion.ally, the bond pattern can negatively impact the quality of the fiber-to-fiber bonds. For, example because 5 conventional bond patterns do not completely bond the nom1oven l•leb, the pressure applied to ·the nom10ven Heb as the non.woven web pass~·s through the calendering rolls can fluctuate. In some cases; the pressur;e fluctuat'ions can cause higher pressures at some fiber-to-fiber bond sites and cause lower 10 pressures at other fiber-to-fiber pond sites. The higher pressur'e·can result in overbonding or even cutting through fibers (which Heakens the resulting Heb). The lo~1er pressure I I I I I I I I j I I I, may result in a reduced percentage of bonded area being formed I '. . '·I compared to the desired percentage of ~ended area, ioHer bond I 15 strength and/or loHer bond quality. Additionally,. ·the lo>~er pressure may cause reduced streng.th in the cross machine direction, Consequently, there is a need to provide a ·fastening . .. . I ' system VThich includes a receiving component havi:ng a bond! 20 pattern which reduces the pressure fluctuations experienced by the receiving component during processing Hhile maintaining sufficient areas of unbonded fibers and/or unbonded portions of bonded fibers. A nonwoven web in accordance with the subject invention 13 I I I I . i can be used for a receiving component (e.g., female component) of a fastener. The nonvroven Heb can have a sufficient fasteningstrength (e.g., peel strength, repeatpeelstrength, ' ' and tensile shear strength) and high mechanical strength in J . 5 both of machine direction (MD) and cros;machine dir~ction (CD) ·I The nomroven ~ings, Hherein like reference numerals are used to .refer i to like elements throughout. In the following de~cription, for p·urposes of explanation:; numerous specific details are set forth in. order to prpvide a thorough understand:icng of th'e subject invention. It may be evident, hoHever,, that the invention can be practiced1·1i thout these specific details. In other instances, well-known structures and devices are shown I ' I ! i ! i I I I I ! 20 in block diagram form in order to facilitate d'escribing the invention. As shol'ln in Fig. lA, a fastening system 10 containing the nonHoven web in accordance Hith the subject invention may contain an engaging component 12 and a receiving component 100. 16 !' I I I The engaging component 12 may contain a plurality of hooks 14 1·1hich extend outHard from: ·an engaging surface 16. The receiving component 100 may contain i'i plurality of loope<:! fibers (not shoHn) Hhich are capable of becoming entangled \•lith 5 the plurality ·Of hooks 14 ·of the engaging component 12. Examples of suitable engaging components are discussed hereafter. The fastening system 10 can be ut.ilized in a variety of. consumer and commercial. goods ~o~hich may benefit from having 10. the fastening system of the subject invention. Some examples 15 . ' of articles ~o~hich can utilize the fastening system·of the subject invention include disposable absorbent articles, body . I ~o~raps, packaging, an. d industrial conne.c tions -for abra'sive pads, i! ·medical products, and the like. As sho~m in Fig. 1B, .. the nom10ven ~1eb 100 that can be used for a receiving component may contain a plurality of bond lines, a bond zone 130, and a plurality of consecutive m1eep regions. In some embodiments, the ·nomwven ~o~eb 100 may I contain a first bond line 110, a second bond line 112, and a i 20 third bond line 114. Embodiments having more than three bond lines and less than three bond lines are contemplated. ·The first bond line 110, in some embodiments, c.an be disposed adjacent to a first end edge 151 and the second bond line 112 can be disposed adjacent to the first bond line 110. 17 ' i I I !. I I I I The t·hird bond line 114, in some embodiments, can be disposed I . adjacent to a second end edge 152 and adjacent the second bond line 112. In some empodiments, the first end edge 151 and the second end edge can extend from a first longitudinal ed.ge 17 0 1 I 5 to a second longitudinal edge 172 .in a direction generallyI parallel to a lateral axis.162. j As shown, in some embodiments, the first bond line 110, I . . I the· second bond line 112, and the third bond line 114, can i ! ·extend in a first d:Lrection 1222 from a •.first longitudinal edge i . I . 10 1.70 to a second longitud~nal edge 172 of the receiving I component 100. In some embodiments, the first direction 12221 . can be ~enerally par.allel to' the lateral axis 162. · The first i 15 20 I longitudinal edge 17 0 and the second longitudinal e.dge 172 can ! extend beh1een the first end edge 151 ·and the second end edge 152 in a direction generally parallel to a longitudinal axis I 160. 1 The nomwven 1-1eb 100 further contains the bond zone 130 ·I The bond zone 130 circumscribes more than one bond line. For I example, as shmin some ernbodirn€nts, two s·Heep regions,; e. g., 142 and 144, ~ontain a porti•;,;· of the first bond line ilo and the ~econd bo~d lirie 112. Depending on the sizes of the sl'leeplI regions, one or :Uore sweep ·regions may contain portions of more I . ' than one bond line. Embodiments containing more than fourj I S\•Ieep. regions and fe\•Ter than four S\•Teep regions are i contemplated. Because the sweep regions 140, 142, 144, and 146, are , consecutive, each sm in Fig, 2A) as the i Heb of fibrous material 275 (shmm in Fig. 2A) passes through I the nip. In some embodiments, the contact length·250 can be. 1 I. determine<;! via the Hertzian equation bel01·1. The Hertzi·an I I I equation assumes that the calendering rolls 202 a·nd 204 are 1 I i 15 made from homogeneous, isotropic material, and further assumes I· the val1idi ty of Hooke's laH. Other assumptions incl.u.de that the calendering rolls 202 and 204 have equal diameters; that the calendering rolls 202 and 204 are created from material l·lhich has the same elastic modulus; and that the Vlidth 220 of 20 the calendering rolls 202 and 204 are at least as 1-lide as the lddth.l7 7 ( shmm in Fig. lB) of the sHeep regions. The contact length 250 can be found via the folloHing equation: X= 25 I I 10. 15 where X is ~ the width of the contact area 250; . R is the radius of the calender roll 202 or 204 in millimeters; F is the force applied in Nm1tons I mm; E is the elastic modulus of the material of the calender rolls I· .202 and 204; L is.the \•lidth of the c·alender rolls 202 and 204 (as shown 220); and v· is PQisson's ratio. Where the calendering rolls do not have equal .diameters, oneskilledintheartcouldrederivetheaboveequationtaking into account the unequal diameters of the calende:<;ing rolls. e·lastic moduli of the calendering rolls. of steel, the elastic modulus E can be equal to about 210,000 · N/mm2 , Poisson's ratio can be about 0:3, and applied force F ' . can be between about 20 N/mm to about 150 N/mm. As mentioned I I ! I I I 20 above·, X is equal to about!.> of the contact length 250. Thus, multiplying X by two provides the contact length 2 50. In some . emb~diments, the contact ai:ea 250 can be in a range from about 0. 1 mm to about 1. 2 mm or any individual number Hi thin the range. In some embodiments, the contact area 250 can be in a range 26 from about 0.7 mm to about 1.0 mm. One advantage of the. subject invention is that because of the ratio of larger bonded area to lesser bon4ed of the subject invention, . pressure fluctuations during the 5 calendering process can be reduced. For example, in COm;:entional receiving COmponents \·There bond areas Vary among s1·ieep· regions by more tha·n 2000%, the contact area of the calendering' rolls producing these bon'ded areas varies by more than 2000% also. Consequently, if the· force applied to the 10. calender rolls is cons~arit, the pressure applied to a web of i fibrous material as it pa,;ses through the nip of the calender rolls varies by more than 2000% as well. In conventional receiving components pressure fluctuations of greater than 2000%. can occur 'i·lhen some· sto~eep regions contain a 0% bonded 15. area, thereby yielding a ratio ·of larger bonded area to lesser bonded area Hhich is infinite. The zero percent bonded area. ·can occur, for example, •1hen a first bond line and a second bond line are separated by a finite distance in a direction generally parallel to the longitudinal' axis of the ·receiving 20 component l·lhich is equal to at least the length of a sweep region. As another example, pressure fluctuations ;of greater than 2000% can also occur where there is too much overlap bet~een bond lines or too little. The overlap between bond lines is discussed further with regard to Figs. 3A, 3B, and 27 I I I I I .. )0 15 .3C. From a process perspective, the pressure fluctuations of greater than 2000%:can cause process instabilities. For ex'ample, the extreme pressure fluctuations can cause premature failu.re of the protrusions on the calender rolls. ::: )i'rom. a product/material perspective • performance • . :.

' . ·typically desir<>ble. : F.or example, a· sHeep region ,having 0% bonded area can provide loH shear. capability and p6tentially poor refastehability res~lts. Specifically, because less loose fiber ends are bonded 1dthin this sHeep region, fuzzing· can result during multiple. openin<:r and closing cycles 1·1ith suitable engaging components. Also, s1·1eep regions having 0% bonded area can reduce the strength in a direction parallel to a· lateral axis of the receiving component.. The lateral axis of the receiving component, in some embodiments can be associated Hith the direction of shear in many instances. For example, in a fastened state, the lateral axis of the receiving component 20 can be generally parallel to the direction of shear. For. example, referring to Fig. SA momentarily, in a fastened state, . shear forces can act along a primary direction of shear 775 Hhich is generally parallel to a lateral axis of a receiving component 740. \'/here there is no overlap between ·adjacent 28 I I I I I I i I I I I I I I I I ! ' I I I I I '' ' . 1\, 5 10 15 bcind lines, the. receiving component material in between adjacent bond lines remains free to move i·li th the applied shear force. In contrast, l·lhere the overlap between bond lines causes pressure fluctuations of greater than 2000%, the concentration of·fiber-to-fiber bond sites in the region of overlap will generally .provide poor fastenabili ty results. For exampl'e, as stated previously, engaging components generally are not able to engage receiving components at the bonded areas. ·Additionally, the pressure fluctuations of greater than 2000% can also cause variable bonding quality, as discussed previously. . When pressure fluctuations are greater than i i I I I I I I I I I I I I I I 2000%,· fiber-to-fiber bonds in the lesser bonded area sweep I regions experience higher pr'essure than large} bonded area· I ' I sweep regions and can incur holes because of the. higher pressure. Also, the fiber-to~ fiber-bonds in the .larger ! bonded area sweep re~ions can experience lower pressure. than ·i ' lesser bonded area sweep regions and can iricur less fiber-to-fiber bonds because of the lower pressure. 20 Specifically, the lower pressure, in some cases, can merely compress fibers instead of actually bonding them. As shovm in Fig. 2C1 a receiving component 30 Has constructed in accordance with the subject invention and incurred some defects, e.g. r 32, 3 4. 3 6. 38, 40, and 42. ·I 29 · HoHever, Hhen the bond ratio of the receiving component 30 is about 20 or less, for example, about 1.8, the number of the defects is Hi thin an all01iable range. In contract, 1·1hen the bcind ratio is above 20 or more, an unacceptable amount of 5 de.fects may occur in a receiving component. In contrast 1-lith conventional receiving components, a· receivin.g component containing the nonwoven web in kccordance . ~lith the subject invention reduces pressure fluctuations belm1 about 2000%. The reduction in pressure fluctuaticln, in part, 10 :is accompiished by ass.urinp that a bond area of the receiving c~mponent contains a plurality of SI·Jeep regions Hhich each have some finite amount of bonded area. Additionally, the s~ieep regions for receiving• components containing the nom10ven l·leb in accordance \•li th the subject invention contain bonded area Hi percentage~ Hhich reduce pressure fluctuations belo0 about 2000%. 'I I There are several factors 11hich can impact the ratio of 1. i I ! larger bonded area to lesser bonded area. Some factors in·clude the overlap of the bond lines, in some embodiments, i 20 the orientation angle of the bond lines, the period of the bond I lines, and in some embodiments, the orientation df the bond lines during processing. The orientation of the bond lines. during processing is discussed further in regard to Fig. 6. As sh01m in Fig. 3A, the overlap 320 is a distance beb1een 30 a first reference line 302 and a second reference line 304. In some embodiments, the overlap 320 is generally parallel to the longitudinal axis 160 and generally parallel to a second direction 1223. The first reference line 302,1 in some .

As shOI·In, see Examples 1 and 4, as the overlap increases, the ratio of larger 10 area to lesser area decreases. The overlap can.be impacted by the thickness of the bond lines. For example, in Table 1, as the thicknesses of the bond lines decrease, the overlap betl-1een the bond lines can similarly decrease (see Examples 1 and 2). Additionally, the 15 thickness of all the bond lines in one pattern can be changed 34 I I I I I I I 5 as de_sired to adjust the overall percent bonded area of the· bond pattern.

Hol·rever, one skilled in the art 10· couLd calculate the vaLues for the listed parameters in Tables' i, 2, .a..n d 3, for any given:bond line pattern or variations theieof. For example; for simple geometries, e. g., co·nsisting of angled and connected straight lines, the values shown in Tables 1, 2, and 3, can be calcuLated using the 15 geometric and trigono.metric relationships of the angled and connected s.traight lines as done for the bond line patterns shoHn heretofore. For more complex patterns, for example, those sh01m in Figs. 4A-4K, or bond line patterns. including shapes s,uch as those of Figs. 5B-5E, the values of Tables 1, 20 2, and 3, can be obtained by utilizing computerized image analysis. In computerized image analysis,. the bond pattern in question is digitized such that a color contrast can be reliably measured to dete.rmine Hhere bonded and unbonded areas· 3'9 are. For example, unbonded areas may be represente,d as 1•1hite pixels and bonded areas may be represented as black .pixels. The number of pixels representing a bonded area can pe counted and compared to number of pixels representing an unbonded area 5 to determine the percentage of bonded area. Similarly, the period, overlap, bond line thickness, orientation angle, and· line sp~cing can also be.measured using computerized image analysis, Additionally, any data or trends discussed in regard to 10 Tables 1, 2, arid 3, are pertinent to the bond line patterns analyzed, e.g., zigzag pattern.
