3. PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the Invention and the manner in which it is to be performed

FIELD OF INVENTION:
The present invention relates to a novel textile fabric. More particularly, the present invention relates to the single textile fabric with Decorative Engineered self- hem wherein the decorative hem is a part of the fabric and it is not achieved by sewing /joining of another fabric to get the decorative hem on the sheets/ sheet sets / bedding etc.
BACKGROUND & PRIOR ART:
A hem in sewing is a garment finishing method, where the edge of a piece of cloth is folded narrowly and sewn to prevent unravelling of the fabric. In a most common hemming method, a cut edge is folded and is then sewn. With this method, the cut edge is completely enclosed in the cloth so that it cannot unravel. Three basic forms of hems can be used in the process of constructing garments: turned-up edge, faced edge, and enclosed edge. The most common technique used is the turned-up edge hem. After the hem is constructed, the following criteria should be met: 1) the garment should hang on the body in a uniform and even manner; 2) the hem should be free of bulk, and 3) the hem should be concealed from the eye unless used for decorative purposes. Generally, the hem is done at the edge of the fabric or near a selvedge area. The selvedge area is a self-finished edge of fabric.
The most important attributes of any bedding items are the look and design of the product. To enhance the beauty of bed linen lot of embellishments are generally done on the hem of the products. In market almost all Flat sheets, Pillow cases, cushions, duvet covers etc. are embellished with some designs, different cut & sew style, by joining different fabric to Hem or by embroidery in hem. Lot of designs or embellishment causes additional duty on the products in the US. Due to embellishments lot of skill sets are required in cut & sew and it also reduces the production efficiency.
In recent times there are fabrics prepared using two different materials stitched at a distance of 5-10 inches from the selvedge area to provide aesthetic appearance. However, the same involves huge costs as it involves two different materials, cutting and sewing. Moreover, the same involves additional import duty on the product in US. There is limited literature available on the engineered self- hem as provided below.

CN102524993 discloses a method for processing a hem of a men's suit, which includes steps: firstly, cutting a back hem interlining according to size designation of the suit and using twill hair interlining strips 5-7 cm in width; secondly, aligning the hem interlining with a hem fold notch, allowing the lower end of the hem interlining to be parallel to the hem, and allowing two ends of the hem interlining to be 0.3-0.4 cm away from a slit fold point; thirdly, straightening out the hem interlining, uniformly basting three lines to fasten the hem interlining, performing blindstitch to evenly sew three lines close to the basted lines to hold the hem interlining; fourthly, stitching the slit, press-opening the slit, and fold-ironing the hem edge 4-5cm; and fifthly, sewing up the shell and the lining of a back slit, basting to fasten the hem edge, and performing blindstitch to fasten the hem edge 0.7-1.5 cm away from a rough selvedge. The hair interlining strips are used in the method to substitute nonwoven interlinings, the hem of the made suit is linear and soft to touch, and naturally fits a human body, and accordingly the level of the product is increased.
Therefore, there is a need in the art to provide self-engineered hem that is capable of overcoming the above issues yet provide excellent smart look on the product. Therefore, it is an object of the invention to provide self-engineered hem, the innovative design without any additional cut & sew and a simple process for preparing the same.
SUMMARY OF INVENTION:
The present invention discloses a decorative engineered self-hem and a method to prepare the decorative engineered self-hem in a single fabric. The hem is engineered at a distance of 10-20 inches from the selvedge area with various weave patterns.
In a preferred embodiment, the fabric is woven by creating a design in a range 10-15 inches from the selvedge area of the fabric and the rest of the fabric is woven with conventional method. It is then processed and finished and then cut & sewn in a way that the hem is created in a range 4-6 inches from the edge area of the sewn product.
A method to prepare a decorative engineered self-hem in a single fabric, according to the present invention comprises, a first step of cutting the fabric parallel to a selvedge area; a second step of folding the fabric overlapping the selvedge area; and a third step of folding

the full fabric horizontally and at the same time, hemming of edge of the selvedge area to finish wherein self-engineered hem is designed during weaving without having any additional cut & sew. Using the above method, various weave patterns are designed 10-20 inches from the selvedge area and rest of the fabric is woven in conventional weave pattern such as satin/twill./ Percale/ Oxford.
BRIEF DESCRIPTION OF DRAWINGS:
Fig. 1 illustrates steps of decorative engineered self-hem of the present invention.
DETAILED DESCRIPTION:
Accordingly, the present invention discloses a decorative engineered self-hem and a method to prepare the decorative engineered self-hem in a single fabric.
Accordingly, in a preferred embodiment, the invention provides self-engineered hem that is designed during weaving without having any additional cut & sew. During weaving of conventional sheeting fabric, mills generally do the weaving in different pattern like satin, twill, percale, oxford etc.
However, the present inventors have engineered 10-20 inch from the selvedge area with various weave patterns, and the rest of the fabric is woven in conventional weave pattern like Percale/ oxford/ satin/twill. After processing and finishing of the fabric the Cut & Sew is done in such a manner that the hem is created from the 10-20 inches of the fabrics which was woven in different design. The fabric can be constructed with plurality of warp yarn, plurality of count weft yarn. Hence, the present invention provides embellished flat sheets, pillow covers, Shams, cushions/ cushion covers, Duvet covers, table covers, curtains and other bedding products with exceptional new creative look and pattern.
In a preferred embodiment, the fabric is 100% cotton woven and can be done in any fiber or any blend, woven satin or any weave in the body and 10-20 inches from the selvedge side are woven with different weave/design pattern. The fabric is preferably constructed with 60s warp yarn and 60s count weft yarn and final thread count is 300, but can be done in 40s, 60s, 80s, 100s, 120s yarn count and thread count of 200TC and above. However,

the yarn count stated here is for exemplary purpose and do not restrict the scope of the invention. Fig. 1 represents steps of the decorative engineered self-hem of the present invention. Fig. l(i) shows a fabric having a width (3) and containing a selvedge area (1) and design area (2). As illustrated in Fig. l(ii), the fabric is cut and folded (5). At the same time, an edge (4) of the selvedge area (1) is folded to hem finish. Having finished these steps, the final product which is rectangular in shape is created, as illustrated in Fig. l(iii).
In another preferred embodiment, the invention provides process for preparation of self-engineered hem. After weaving, the fabric is processed in a conventional process route. Before stitching the fabric is cut as per required dimension i.e as per required product size. The "S" hem sewing technique has been done after taking innovative designing on the hem area. The conventional process includes singeing and desizing, desizing wash, pretreatment, mercerization, dyeing and finishing.
Accordingly, a method to prepare a decorative engineered self-hem in a single fabric, according to the present invention comprises, a first step of cutting the fabric parallel to a selvedge area; a second step of folding the fabric overlapping the selvedge area; and a third step of folding the full fabric horizontally and at the same time, hemming of edge of the selvedge area to finish wherein self-engineered hem is designed during weaving without having any additional cut & sew.

We claim,
