Abstract

The utility model discloses a polyester-nylon vertical pile corduroy-like double-sided fabric which comprises a front vertical strip structure unit, a spacing unit and a back vertical strip structure unit, and the three units are formed by vertically interweaving warp yarns and weft yarns. Wherein the warp yarns comprise two groups of yarns, the first group of warp yarns and the weft yarns are interwoven to form vertical strip structure units on the front and back surfaces of the fabric, and the second group of warp yarns and the weft yarns are interwoven to form spacing units between two adjacent vertical strips. The front vertical bar unit and the back vertical bar unit are each composed of a plurality of warp floating long lines which are sequentially arranged in the warp direction, and the floating long lines on the front face and the back face are equal in length and symmetrically distributed. Each interval unit is formed by arranging one warp weave point and one weft weave point at intervals. The warp floating long lines of the vertical strips on the front face and the back face are obtained by sequentially arranging polyester-nylon superfine fiber interlaced large-diameter high-shrinkage filaments in the warp direction. The polyester-nylon superfine fibers are subjected to splitting and napping in the dyeing and finishing processing link to form dense fluff, and the obtained vertical-strip corduroy is more three-dimensional when being matched with the high-shrinkage yarns for use. And the vertical strips are connected by the interval organization units to form clear raised fluff strips and grooves. Clear vertical strips are arranged on the front and back surfaces, so that the double-sided cloth has the appearance effect of composite velvet.

Description

Technical Field

[0001] This utility model relates to the field of textiles, and in particular to a double-sided polyester-nylon striped corduroy-like fabric. Background Technology

[0002] Commercially available corduroy typically features a double-layer pile-weft structure. The base weft and warp yarns form the fabric's foundation, secured using a "V" or "W" shaped knot to fix the pile weft yarns to one side of the fabric. The pile weft is then cut by a pile-cutting machine, and brushing separates and raises the face yarns. The resulting corduroy is three-dimensional, full, comfortable, and aesthetically pleasing. However, with the continuous advancement of industrialization and modernization, people's clothing increasingly needs to alleviate the pressure and tension brought about by the speed, order, and mental stress of modern life. Corduroy fabrics, primarily made of polyester-nylon microfiber, combined with a multi-layer pile-weft structure, allow the two sides of the fabric to present different pile styles, perfectly catering to the current trends of casualness, diversification, high-quality products, and comfort. Through optimized structure, the fabric possesses the three-dimensional appearance of corduroy from the initial fabric production stage, eliminating the need for pile cutting and thus improving production efficiency to some extent. Summary of the Invention

[0003] To address the aforementioned technical problems, the purpose of this invention is to design a polyester / nylon vertical stripe imitation corduroy double-sided fabric. This fabric combines alternating double-weave and plain-weave structures in its manufacturing process, resulting in a three-dimensional, full vertical stripe effect on both sides. After fiber opening, napping, and setting treatments, the vertical stripes form a delicate and full pile effect. Notably, because the vertical stripe imitation corduroy is formed during manufacturing, it does not require weft-breaking treatment, thus preserving the continuity of the pile weft yarns and eliminating problems such as pile weft shedding and pilling during wear.

[0004] To achieve the aforementioned technical objectives and effects, this utility model provides the following technical solution: a double-sided polyester-nylon striped corduroy-like fabric, characterized in that it comprises a front vertical stripe structural unit, a spacing unit, and a reverse vertical stripe structural unit, all three units being formed by the vertical interlacing of warp and weft yarns. The warp float (hereinafter referred to as "warp") indicates that at the point where warp and weft yarns interlace, the warp yarn is on top and the weft yarn is on the bottom; the weft float (hereinafter referred to as "weft") indicates that at the point where weft yarns interlace, the weft yarn is on top and the warp yarn is on the bottom. The warp yarns comprise two sets of yarns. The first set of warp yarns interlaces with the weft yarns to form the front and reverse vertical stripe structural units of the fabric, wherein the warp yarns forming the front vertical stripe unit are called the outer warp, and the warp yarns forming the reverse vertical stripe unit are called the inner warp. The second set of warp yarns interlaces with the weft yarns to form the spacing units between the vertical stripes. The vertical stripe structural units on both sides consist of nine floats arranged sequentially along the warp direction. Each float on the front vertical stripe has four face warp floats, and each float on the back vertical stripe has four back warp floats. The spacer unit is located between two adjacent vertical corduroy units and consists of one warp weft weft weft weft alternating between them. The warp floats on both sides are obtained by arranging polyester-nylon microfibers along the warp direction. After the polyester-nylon microfibers are opened and napped during the dyeing and finishing process, they form a dense pile. Both the front and back stripes are connected by spacer units, making the vertical stripes protrude from the fabric surface, resulting in a more three-dimensional and fuller corduroy.

[0005] Furthermore, in the first group of warp yarns, the outer warp numbers are 8, 10, 12, 14, 16, 18, 20, 22, and 24, and the inner warp numbers are 9, 11, 13, 15, 17, 19, 21, 23, and 25. The second group of warp yarns is numbered 1, 2, 3, 4, 5, 6, and 7.

[0006] Specifically, the warp and weft arrangement of the 8th and 18th yarns in the face is 4 warp, 1 weft, 4 warp, 1 weft; the warp and weft arrangement of the 10th and 20th yarns is 3 warp, 1 weft, 4 warp, 1 weft, 1 warp; the warp and weft arrangement of the 12th and 22nd yarns is 1 weft, 4 warp, 1 weft, 4 warp; the warp and weft arrangement of the 14th and 24th yarns is 1 warp, 1 weft, 4 warp, 1 weft, 3 warp; and the warp and weft arrangement of the 16th yarn is 2 warp, 1 weft, 4 warp, 1 weft, 2 warp.

[0007] Furthermore, the warp and weft arrangement of the 9th and 19th yarns in the inner warp is 2 weft 1 warp 4 weft 1 warp 2 weft; the warp and weft arrangement of the 11th and 21st yarns is 1 weft 1 warp 4 weft 1 warp 3 weft; the warp and weft arrangement of the 13th and 23rd yarns is 3 weft 1 warp 4 weft 1 warp 1 weft; and the warp and weft arrangement of the 15th and 25th yarns is 4 weft 1 warp 4 weft 1 warp.

[0008] Furthermore, the warp and weft weft arrangement pattern of the 1st, 3rd, 5th, and 7th yarns in the second group of warp yarns is 1 weft 1 warp 1 weft 1 warp 1 weft 1 warp 1 weft 1 warp 1 weft 1 warp 1 weft 1 warp, and the warp and weft weft arrangement pattern of the 2nd, 4th, and 6th yarns is 1 warp 1 weft ....

[0009] Furthermore, in the first group of warp yarns, both the outer warp and the inner warp are cross-linked polyester / nylon low-elasticity yarns with high shrinkage. The linear density of the polyester / nylon low-elasticity yarn is 167 dtex / 72f, and the linear density of the high-shrinkage yarn is 64 dtex. The ratio of the outer warp to the inner warp is 1:1.

[0010] Furthermore, the second set of warp yarns is made of low-elastic polyester yarn with a linear density of 111 dtex / 72f.

[0011] Furthermore, the weft yarn is made of low-elastic polyester yarn with a linear density of 167 dtex / 144f.

[0012] Furthermore, the number of vertical stripes on the front and back of the corduroy-like fabric is 8 strips per inch, the strip width is 0.3cm, and the gap width between the strips is 1mm.

[0013] Furthermore, the ratio of the first group of warp yarns to the second group of warp yarns in the double-sided fabric is 7:18, the density of the first group of warp yarns is 460 yarns / 10cm, and the density of the second group of warp yarns is 170 yarns / 10cm. The weft yarn density is 240 yarns / 10cm.

[0014] Furthermore, the weight per square meter of the double-sided fabric is 180-200 g / m², and the width is 180-190 cm.

[0015] The beneficial effects of this invention are as follows: The vertical stripes on both sides of this invention are made from large-diameter, high-shrinkage polyester-nylon low-elasticity yarn interwoven composite yarn. Multiple yarns are arranged sequentially to form a raised corduroy effect on the fabric surface. During the dyeing and finishing process, the high-shrinkage yarn shrinks fully after dyeing and finishing, causing the interwoven polyester-nylon low-elasticity yarn to shrink as well, resulting in a more three-dimensional and fuller stripe. Specifically, after the polyester-nylon low-elasticity yarn undergoes high-temperature alkali finishing, the single fiber splits from one into 16 fibers, increasing the number of single fibers by 16 times, resulting in a single fiber linear density of less than 0.14 dtex. The microfiber provides a soft and comfortable feel to the double-sided fabric and also facilitates the napping process, resulting in a delicate, clearly defined, and three-dimensional vertical stripe. Simultaneously, the optimized weave structure design allows both sides of the fabric to exhibit a corduroy-like style, achieving a composite fleece effect. Attached Figure Description
