Abstract
The present disclosure relates generally to the technical field of fabrics. More specifically, the
present disclosure pertains to a woven textile fabric with higher thread count that exhibits low
pilling tendency, while being economical.
Description
[00011 The present disclosure relates generally to the technical field of woven fabrics. More specifically, the present disclosure pertains to a woven textile fabric with higher thread count that exhibits low pilling tendency, while being economical.
[0002] Pilling is a condition that arises in fabrics due to the formation of little 'pills' of entangled fibers clinging to the fabric surface giving it an unsightly appearance. They are formed by a rubbing action on loose fibers, which are present on the fabric surface. It was originally a fault found mainly in knitted woollen goods made from soft twisted yams. However, introduction of man-made fibers into clothing has aggravated its seriousness because these fibers are stronger than wool so that the pills remain attached to the fabric surface rather than breaking away as would be the case with the wool. Pilling, in general, affects the appearance of fabrics and reduces the use performance of fabrics; however, it may not affect the durability or functionality of the fabric per se.
[00031 There are several ways to preclude pilling or decreasing pilling tendency of a fabric. One solution is singeing process and spinning the yam with a high number of twists per inch. '0 Other methods include chemically treatment of the fabric during the manufacturing process in order to reduce their propensity to pill. Sometimes polymeric coatings are also applied to bind fibers into the fabric surface and prevent initial fuzz from forming. However, all these method suffers from one or more limitations as would be apparent to persons skilled in the art.
[00041 Accordingly, there remains a long felt need in the art for a woven textile fabric with higher thread count that exhibits low pilling tendency. It is always desirable if such fabric would be economical.
[0005] An object of the present disclosure is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
[00061 Another object of the present disclosure is to provide a woven fabric that has an increased thread count.

Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written
[0026] An aspect of the present disclosure provides a woven textile fabric, said fabric comprising: 132 to 190 ends per square inch (EPI) cotton warp yarns; and multi-filament polyester weft yarns, wherein the cotton yarns have a cotton count of 30s to 80s, the multi filament polyester yarns have a denier of 8D to 50D, and the fabric has a high total thread count ranging from 500 to 3000, and wherein the multi-filament polyester yarns are wound, '0 substantially parallel to one another and substantially adjacent to one another, on a multi-pick yarn package at an angle between 15 and 30 degrees and at a type A shore hardness between 60 to 90 to enable simultaneous insertion of the multi-filament polyester yarns during a single pick insertion event of a pick insertion apparatus of a loom.
[00271 In an embodiment, the fabric exhibits rating of 3 or above when the fabric is tested for pilling for 1000 rubs. Any of the methods as known to or appreciated by a person skilled in the art for testing of pilling resistance, such as ASTM D4970 and ISO 12945-2. In an embodiment, the fabric exhibits rating of 3 or above when the fabric is tested for pilling for 1000 rubs in accordance with ASTM D4970. In an embodiment, the fabric exhibits rating of 3 or above when the fabric is tested for pilling for 1000 rubs in accordance with ISO 12945-2:2014. ASTM D4970 and ISO 12945-2 methods make use of a Martindale Tester, wherein the fabric (i.e. the finished fabric) being tested is rubbed face to face for a specified number of rubs/cycles, and the pill balls are evaluated using a photographic visual standard for comparison and given a 1 - 5 rating, wherein rating/grade 1 indicates very severe pilling and rating/grade 5 indicates no pilling.
[0028] In an embodiment, the cotton yarn comprises 100% cotton yams. Alternatively, the cotton yarn may comprise blend of cotton and any or a combination of a synthetic fiber and a natural fiber such that the blend has a cotton content of at least 90%. In an embodiment, the multi-filament polyester yarns comprise 100% polyester multi-filament texturized yams.
[0029] In an embodiment, the proportion of the cotton in the fabric is 50% or above by weight of the fabric. Simply put, the content/proportion of the cotton in the fabric is higher than that of the Polyester.
[0030] In an embodiment, the multi-filament polyester yams have a denier of 8D to 30D. In an embodiment, the fabric comprises 368 to 2868 picks per square inch (PPI) multi-filament polyester yarns. In an embodiment, the multi-filament polyester yarns comprise 7 to 28 filaments.
[0031] In an embodiment, the fabric comprises any of a twill weave and a satin weave. In an embodiment, the fabric comprises a twill weave.
[0032] In an embodiment, the cotton yams have a cotton count of 40s to 60s. In an embodiment, the multi-filament polyester yarns are wound on the multi-pick yam package at an angle (winding angle) between 15 and 25 degrees. In an embodiment, the multi-filament '0 polyester weft yarns are wound on the multi-pick yarn package at a type A shore hardness between 65 to 80. In an embodiment, the multi-filament polyester weft yarns are woven into the fabric in a group of at least two multi-filament polyester weft yarns, said at least two multi filament polyester weft yams being substantially parallel to one another and substantially adjacent to one another.
[0033] Table 1 below illustrates properties of the fabric, realized in accordance with embodiments of the present disclosure. Table 1: Properties of the Fabric Sample Polyester Polyester Cotton Cotton Feel Pilling Tensile Total No. Weft filaments Yarn content Factor (1-5) Strength thread (Denier) Count (%) (1-5) (1-10) Count 1 12 14 50 54 3 4 7 1500 2 15 14 50 52 3 3 6 1500
3 14 7 60 58 5 4 7 800 4 17 7 60 52 4 3 6 800 5 10 14 60 60 5 3 8 2000 6 20 7 60 48 3 2 5 800 7 20 14 60 40 2 1 6 2000 8 21 14 50 48 1 1 4 1500
[00341 As can be seen from the Table 1 above, when the cotton content of the fabric falls below 50% (i.e. the proportion of cotton in the fabric is less than that of the Polyester), the fabric exhibits high pilling tendency (or low resistance to pilling).
[0035] Table 2 and 3 below illustrates effects of Type A shore hardness and winding angle of the multi-filament polyester weft yams on the instances of yarn breakage and speed of the weaving, which eventually exerts profound effect on the cost of production of the fabric. Table 2: Effect of Type A Shore Hardness Sample Type A Winding Instances of Instances of Average No. shore angle intermingling yarn approximate hardness (average,per breakage weaving bobbin/spool) (average, per speed (looms) bobbin/spool) 1 35 19 200 100 50 2 50 19 125 66 100 3 60 19 30 15 350 4 65 19 5 3 500 5 70 19 2 2 600 6 80 19 7 4 450 7 90 19 15 10 300 8 100 19 200 100 50
Table 3: Effect of Winding Angle Sample Winding Type A Instances of Instances of Average No. angle shore intermingling yarn approximate hardness (average,per breakage weaving bobbin/spool) (average, per speed (loom) bobbin/spool) 1 10 70 150 90 50 2 15 70 25 12 300 3 20 70 2 2 600
4 25 70 10 6 500 5 30 70 35 20 275 6 35 70 90 50 125
[00361 As can be seen from the Table 2 and 3 above, winding angle and Type A shore hardness of the multi-filament polyester yams exerts a pronounced effect on the instances of intermingling of yams, and optimization of winding angle and Type A shore hardness affords dramatic reduction in instances of intermingling and yam breakage without compromising unwinding speed of the yarn.
[0037] The fabric of the present invention exhibits low tendency of pilling, while achieving the balance between feel, pilling resistance and the tensile strength. Further, the fabric of the present invention is significantly economical owing to, at least, reduced wastage during the production and/or increased speed of weaving due to lower instances of yam breakage.
