Description

A TWILL FABRIC COMPRISING COTTON WARP AND POLYESTER WEFT TECHNICAL FIELDS

[0001] The present disclosure pertains generally to the field of textile industry. In particular, the present disclosure provides a woven twill textile fabric that can find utility as home textile. The present disclosure also relates to a method of manufacturing a draw textured yam and a multi-ply separable draw textured yam.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] A woven fabric is any textile formed by weaving and are often created on a loom, and made of many threads woven on a warp and a weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another. These fabric only stretches diagonally on the bias directions (between the warp and weft directions), unless the threads used are elastic. So the properties of two or more threads that are woven together decide the characteristic of the end fabric. Hence, understanding and predicting the structure and properties of woven textiles is very important for achieving specific performance characteristics in various woven applications.

[0004] Textiles that may come in contact with the human skin for example underwear, towels, T-shirts etc. should be comfortable to human being. One easy way of achieving the same is to use cotton as a fabric material. Cotton has high breathability, absorbency, softness and is comfortable to wear. However, cotton may not be sturdy when utilized for making fabric that is used in tough environments such as heavy duty washing machine etc.

[0005] To overcome such limitations cotton yarns can be woven in combination with other synthetic fibers. Further, decreasing the denier of the textile fiber may also increase the comfort. Utilization of these fine yams may increase the thread count of the fabric. An increased thread count represents the superiority of a textile over other textile fabric. However, fine synthetic yams may break when fed into a loom apparatus. Hence, cotton polyester hybrid weaves are limited to larger denier synthetic yarns that the loom may effectively use. Thus, the thread count, and the comfort, quality and lavishness associated therewith is limited.

[0006] Different combination of cotton and synthetics are tried conventionally to form a textile fabric with desired characteristic such as comfortable towards skin, breathability, strength and stretchability. Twisting the two yarns together prior to use as a single yarn in a weaving process also increases the sustainability of the yarn/fabric as it may increase the thread count to some extent. However, these yarns are still susceptible to break in a loom apparatus and the end fabric also exhibits low quality and comfortability.

[0007] There is, therefore, a need in the art to provide a comfortable, breathable, high strength, high quality cotton-polyester hybrid woven twill textile fabric that can find utility as home textile. The present disclosure satisfies the existing needs, as well as others and alleviates the shortcomings associated with conventional cotton-polyester hybrids.
