Technical Field
The present invention relates a cloth that is excellent
in terms of not only flame retardancybutalso stretchability,
and also to a textile product using the cloth.
Background Art
[0002]
As work clothes worn by people engaged in activities
where they may be exposed to flames, such as firefighting and
activities in electric power or chemical companies, clothes
usinga flame-retardant clothhavebeenuse dint hepast. Such
flame-retardant cloths use flame-retardant fibers such as
meta-aramid fibers and para-aramid fibers. Further, it is
said that such flame-retardant fibers generally have poor
stretchability.

[0003]
Asmethods for imparting stretchabilityto a clothusing
a flame-retardant fiber, a method in which a cloth is formed
using an elastic yarn together with a flame-retardant fiber
(see, e.g., Patent Document 1, Patent Document 2, and Patent
Document 3), a method in which a flame-retardant fiber is
twisted, heat-set, and untwisted, and then a cloth is formed
using the flame-retardant fiber (see, e.g., Patent Document
4, Patent Document 5, and Patent Document 6), etc., have been
proposed.
[0004]
However, with respect to a cloth using an elastic yarn,
there have been problems with heat resistance, flame
retardancy, chemical resistance, and the like. Meanwhile,
with respect to a cloth using a flame-retardant fiber that has
been twisted, heat-set, and untwisted, there have been
problems in that its stretchability decreases during weaving,
postprocessing, andwearing, andalso theproblemof increased
cost.

Mode for Carrying Out the Invention
[0012]
Hereinafter, embodiments of the invention will be
described in detail.
The composite yarn in the invention includes a spun yarn
and a conjugate fiber. The spun yarn contains a
flame-retardant fiber having a limiting oxygen index
' !
I (hereinafter sometimes referred to as "LOI") of 25 or more
(hereinafter sometimes simply referred to as "flame-retardant
fiber") . Incidentally, the limiting oxygen index is measured
in accordance with JIS K7201.
Examples of such flame-retardant fibers include
meta-aramid fibers, para-aramid fibers, polyparaphenylene
benzoxazole fibers, polybenzimidazole fibers, polylmide
fibers, polyetherimide fibers, polyamideimide fibers, carbon
fibers, polyphenylene sulfide fibers, polyvinyl chloride
fibers, flame-retardant rayon, modacrylic fibers,
flame-retardant acrylic fibers, flame-retardant polyester
fibers, flame-retardant vinylon fibers, melamine fibers,
fluorine fibers, flame-retardant wool, and flame-retardant
cotton. At least one of these flame-retardant fibers may be
used.
(00131
Among them, in terms of having an excellent limiting
oxygen index and also of excellent mechanical properties,
meta-aramid fibers, that is, metaphenylene isophthalamide
fibers (commercially available products are cone^"^^
manufactured by Teijin Limited, "NomexrfTMm anufactured by Du
Pont, etc.) are preferable. Further, it is also preferable
to mix para-aramid fibers, that is, paraphenylene
terephthalamide fibers (commercially available products are
n ~ ~ ~ ~ ~ma~nurfacctu'rerd ~ b y Teijin Limited, "Ke~lar"'~~
manufactured by Du Pont-Toray Co. Ltd., etc.) and
co-paraphenylene/3,4'-oxydiphenylene terephthalamide fibers
(commercially available products are "Te~hnora"~~
manufactured by Teijin Limited, etc. )
[0014]
As long as the object of the invention is not impaired,
these flame-retardant fibers may also contain additives, such
as antioxidants, UV absorbers, heat stabilizers, flame
retarders, titanium oxide, colorants, and inert fine
particles.
[0015]
It is most preferable that the spun yarn is made only
of the flame-retardant fiber, but non-flame-retardant fibers
(fibers having a limiting oxygen index of less than 25) may
also be contained. In this regard, examples of
non-flame-retardant fibers include polyester fibers, nylon
fibers, rayon fibers, polynosic fibers, lyocell fibers,
acrylic fibers, vinylon fibers, cotton, hemp, and wool. At
least one of these non-flame-retardant fibers may be used.
[0016j
As long as the object of the invention is not impaired,
these non-flame-retardant fibers may also contain adriitives,
such as antioxidants, UV absorbers, heat stabilizers, flame
retarders, titanium oxide, colorants, and inert fine
particles.
[0017 j
In the flame-retardant f lber and the
non-flame-retardant fiber, it is preferable that the fiber
length is within a range of 35 to 110 mm.
[0018]
The total fineness of the spun yarn may be suitably
selected in consideration of surface appearance, heat
resistance, heat protection, stretchability, texture, andthe
like according to the intended use. In particular, it is
preferable that the spun yarn has a fineness within a range
of 58 dtex (equivalent to a single yarn of English cotton count
No. 100) to 580 dtex (equivalent to English cotton count No.
10).
[0019]
In addition, in terms of excellent spinning-process
passing properties and also of application to garments where
flexibility is required, it is preferable that the spun yarn
has .a single-fiber fineness within a range of 0.6 to 5.5 dtex.
[0020]
In terms of the physical properties and flexibility of
the cloth, it is preferable that the spun yarn has a twist
coefficient K within a range of 2.5 to 4.5. Here, T = K dn,
T is the number of twists per inch (2.54 cm) , n is an English
cotton count, and K is a twist coefficient.
[0021]
In addition, the spun yarn may be a single yarn or a
two-ply yarn.
[0022]
The conjugate fiber in the invention is made of two
components put together in a side-by-side manner or an
eccentric sheath-core manner. When the composite yarn
contained in the cloth of the invention of the present
application contains the conjugate fiber in addition to the
above spun yarn, during the heat treatment of the cloth, the
conjugate fiber takes a three-dimensional coil-like crimped
configuration, whereby stretchability is imparted to the
composite yarn, and, as a result, the cloth also has
stretchability imparted.
[0023]
Here, the two components formingthe conjugate fiber may
be a combination of polyester and polyester, a combination of
polyester and nylon, or the like, for example. More
specifically, preferred examples thereof include a
combination of polytrimethylene terephthalate and
polytrimethylene terephthalate, a combination o f
polytrimethylene terephthalate and polyethylene
terephthalate, and a combination of poly~lhylene
terephthalate andpolyethyleneterephthalate. In this regard,
it is preferable that the two components have different
intrinsic viscosities. It is also possible to add additives,
such as antioxidants, UV absorbers, heat stabilizers, flame
retarders, titanium oxide, colorants, and inert fine
particles.
[0024]
In the conjugate fiber, the shape of the fiber is not
particularly limited, and it may be a long fiber
(multifilament) or a short fiber. However, it order to obtain
excellent stretchability, a long fiber (multifilament) is
preferable.
[0025]
The total fineness and single-fiber fineness of the
conjugate fiber are suitably selected according to the
intended use, and it is preferable that the total fineness is
within a range of 20to 200 dtex, andthe single-fiber fineness
is within a range of 0.5 to 10.0 dtex.
[0026]
The composite yarn in the invention includes the above
spun yarn and the above conjugate fiber. In this regard, in
order to achieve flame retardancy and stretchability at the
same time, it is preferable that the weight proportion of the
conjugate fiber contained in the composite yarn is such that
the weight proportion of the conjugate fiber is within a range
of 2 to 40 wt% (more preferably 4 to 30 wt%, particularly
preferably 4 to 20 wt%) based on the weight of the composite
yarn.
[0027]
'I
'! Although the compositing method is not particularly
limited, it is preferable that the composite yarn is a plied
yarn or a covering yarn. More specifically, it is preferable
that the spun yarn and the conjugate fiber are subjected to
plying or covering using a commercially available up-twister,
covering machine, Italian twisting machine, double twister,
or the like. In this regard, twist-setting may be performed
according to the required quality. The twist-setting of a
composite plied yarn may be performed by vacuum steam setting
commonly used for the setting of spun yarns. The temperature
at the time of the setting of the composite plied yarn is
preferably within a range of 50 to 95OC (more preferably 50
to 85°C). When the composite plied yarn twist-setting
temperature is too high, the stretchability of the cloth
finally obtained may be impaired.
[0028]
The cloth of the invention is a cloth using the above
composite yarn. In this regard, in order to obtain excellent
flame retardancy, it is important that the weight proportion
of the flame-retardant fiber is within a range of 75 wt% or
more (preferably 75to 95 wt%) basedontheweightofth[: cloth.
In this case, the non-flame-retardant fiber weight proportion
is less than 25 wt%. In the case where the weight proportion
of the flame-retardant fiber is less than 75 wt% based on the
weight of the cloth, this may result in a decrease in flame
retardancy and thus is undesirable.
[0029]
In addition, it is important that the weight proportion
of the conjugate fiber is within a range of 5 to 15 wt% based
!
i on the weight of the cloth. In the case where the weight
j
proportion of the conjugate fiber is more than 15 wt% based
on the weight ofthe cloth, a flame is easilytransmittedalong
the conjugate fiber. This results in increased flammability
and thus is undesirable. In addition, in the opposite case
where theweight proportionof the conjugate fiber is less than
5 wt%, this may result in a decrease in stretchabilityandthus
is undesirable.
[0030]
The cloth structure of the cloth is not particularly
limited, but is preferably a woven fabric or a knitted fabric.
In the case of a woven fabric, plain weaving, twill
::I;
weaving, and satin weaving can be mentioned, for example. In
the case of a knitted fabric, machine knitting, crocheting,
needle knitting, Afghan knitting, and lace knitting can be
mentioned, for example. For example, in the case of a woven
fabric, the composite yarn may be 100% used in the warp
direction and/or weft direction, and it is also possible that
the spinning and the composite yarn are used in a ratio of 1: 1,
2:1, 3: 1, 1:2, or 1:3, for example. Incidentally, the method
for knitting or weaving is not particularly limited, and may
be a method using an ordinary knitting machine or weaving
machine.
[0031]
Here, it is preferable that the cloth is a woven fabric,
and one of the warp and weft of the woven fabric includes the
composite yarn including a spun yarn that contains a
flame-retardant fiber having a limiting oxygen index of 25 or
more and a conjugate fiber that is made of two components put
together in a side-by-sidemanner or an eccentric sheath-core
manner, while the other includes a spun yarn that contains a
flame-retardant fiber having a limiting oxygen index of 25 or
more.
[0032]
Next, the cloth is subjected to a heat treatment, such
as scouring, relaxing, dyeing, or setting. As a result, the
conjugate fiber contained in the cloth, which is made of two
components put together in a side-by-side manner or an
eccentric sheath-core manner, takes a three-dimensional
'.
coil-like crimped configuration, whereby stretchability is
imparted to the cloth.
[0033]
I. The cloth may be additionally subjected to
water-absorbing processing, water-repellent processing,
napping, flame-retarding, UV shielding, or other various
function-imparting processes using an antimicrobial, a
I deodorant, an lnsect repellent, a phosphorescent agent, a
retroreflect~ve agent, a mlnus lon generator, etc.
[0034]
Thecloththus obtainedcontainstheabove composite yarn,
and thus is excellent in terms of not only flame retardancy
but also stretchability.
[0035]
Here, as stretchability, it is preferable that the cloth
has an elongation within a range of 3 to 50% in the warp
direction and/or weft direction. In addition, as elongation
recovery, it is preferable that the cloth has an elongation
recovery of 70% or more (more preferably 73% to 99%) in the
warp direction and/or weft direction. In addition, as flame
retardancy, it is preferable that the cloth has a limiting
oxygenindexof25ormore (morepreferably25to40) asmeasured
in accordance with JIS K7201.
[0036]
Next, the textile product ofthe inventionuse sthe above
cloth. The textile product uses the above cloth and thus has
excellent stretchability and flame retardancy. Such textile
products include firefighter clothes, fireproof clothes,
office clothes, racing suits for motor sports, work clothes,
gloves, hats, bests, andvarious industrialmaterials (sheets,
tents, filmmaterials, hoods, constructionmaterials, housing
materials, car interior materials, etc.). In addition, the
work clothes mentioned above include work clothes for
activities in a steel plant or steel factory, work clothes for
welding, and work clothes in an explosion-proof area. In
addition, the gloves mentioned above include work gloves used
in the aircraft industry, the information equipment industry,
I
1 the precisionmachineryindustry, and the like where precision
components are treated.
Examples
[0037]
Next, examples oftheinventionandcomparatlveexamples
wlll be described in detail, but the lnventlon is not limited
thereto. Incldentally, measurement item sinthe Exampleswere
measured by the following methods.
(1) Flame Retardancy
Limiting oxygen index (LOI) was medsured in accordance
with JIS K7201: 1999 (Polymer Material Burning Test Method by
Oxygen Index Method) and used as an index of flame retardancy.
(2) Stretchability
Elongation and elongation recovery were measured in
accordance with JIS L1096: 2011 (B Method, constant load).
(3) Flarnrnabllity
Afterflame time, afterglow time, and char length were
measured in accordance with JIS L1091, A-4 Method, Appendix
8, and used as indexes of flammability.
[0038]
[Example 11
As a spun yarn, in the spinning process, a short fiber
made of a polymetaphenylene isophthalamide fiber having a
single-fiber fineness of 2.2 dtex, a cut length (fiber length)
of 51 mm, and an LO1 of 33 cone^"^^ manufactured by Teijin
Limited) and a short fiber made of a
co-paraphenylene/3,4'-oxydiphenylene terephthalamide fiber
havinga single-fiber fineness of1.7 dtex, a cut length (fiber
length) of 51 mm, and an LO1 of 25 ('TechnoraUTM manufactured
by Teijin Limited) were spun together in a weight ratio
(former:latter) of 95:5 to give a single yarn of English cotton
count No. 40. The number of twlsts was 20.87 T/2.54 cm (twlst
coefflclent = 3.3).
I [0039]
Meanwhile, as a conjugate fiber, a multifilament (long
I fiber) made of two kinds of polytrimethylene terephthalate
with different intrinsic viscosities put together in an
eccentric sheath-core manner and having a total fineness of
40 dtex/24 fil, an elongation of 26%, and a boiling water
shrinkage of 55.0% was prepared.
[0040]
Next, two of the spun yarns were combined and
second-twisted using a double twister. The number of twists
was 20.9 T/2.54 cm. Subsequently, the yarns were twist-set
using a vacuum steam setter at a setting temperature of 120°C
for a setting time of 20 minutes, thereby giving a
flame-retardant plied yarn A.
[0041]
In addition, two of the spun yarns and one of the
conjugate fiber (multifilament) were combined and
second-twisted using a double twister. The number of twists
was 19.8 T/2.54 cm. Subsequently, the yarns were twist-set
using a vacuum steam setter at a setting temperature of 80°C
for a setting time of 20 minutes, thereby giving a composite
yarn B
Next, 100% using the flame-retardant plied yarn A as the
warp and 100% using the composite yarn B as the weft, they were
plain-woven at a weaving density of warp: 48 yarns/2.54 cm and
weft: 48 yarns/2.54 cm.
[0043]
The formed woven fabric was finished through scouring,
relaxing, and setting (temperature: 190°C x time: 30 seconds).
Here, when the relaxing temperature was 95'C, and a relatively
strong rubbing effect was given, crimps ofthe conjugate fiber
were developed well, and stretchability was developed
particularly well.
[0044]
In the obtained stretchy flame-retardant woven fabric,
the weaving density was warp: 55 yarns/2.54 cm and weft: 48
yarns/2.54 cm, the non-flame-retardant fiber weight
proportion was 6.0 wt%, and the limiting oxygen index was 29.0.
The weft elongation was 7.0%, indicating excellent
stretchability, and the elongation recovery was 75%.
Evaluation results are shown in Table 1.
