Description

Technical Field

[0001] The utility model relates to the field of denim fabrics, in particular to vortex-spun soft denim fabrics. Background Art

[0002] Currently, denim fabrics are mostly woven with cotton yarn in a plain or twill weave, with warp and weft yarns tightly interlaced. The resulting fabrics are typically thicker and have high washability and abrasion resistance. This reduces the fabric's feel and softness. Prior art, such as application number 201520027650.5, describes a soft denim fabric comprising a fabric layer comprising warp and weft yarns, which are perpendicularly overlapped at 90°. The weft yarns comprise double-layer weft yarns and single-layer weft yarns, which are arranged alternately. The double-layer weft yarns include upper and lower weft yarns. A single row of warp yarns consists of four warp yarns, with warp yarns positioned above the upper weft yarn and below the lower weft yarn. Two warp yarns are positioned between the upper and lower weft yarns, and two warp yarns are positioned at each end of the single-layer weft yarn. This fabric utilizes a height difference between the single-layer weft yarn and the double-layer weft yarn. The double-layer weft yarn with this height difference can tilt toward the single-layer weft yarn, providing cushioning and a soft feel. However, the four warp yarns are interwoven with the upper weft yarn, the lower weft yarn and or the single-layer weft respectively, and the weaving method is cumbersome; and due to the height difference between the weft yarns, the flatness of the fabric is reduced, the washing resistance is reduced, and the fabric is easy to change after washing.

[0003] Vortex spinning is a new spinning technology. Compared with traditional ring spinning, it offers advantages such as a shorter spinning process, higher production efficiency, online quality monitoring, and a high degree of automation and intelligence. It also significantly reduces labor requirements and yarn hairiness. Therefore, there is an urgent need to develop a soft denim fabric that incorporates vortex spinning. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a vortex-spun soft denim fabric. The denim fabric has good wear resistance and washability because the adjacent warp yarns are interlaced with each other to form a tightly overlapping woven structure. Larger pores are formed between adjacent main warp yarns, which has good air permeability and improves the softness of the fabric.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] Vortex-spun soft denim fabric includes main warp yarns and main weft yarns interwoven with the main warp yarns. Each main warp yarn is wrapped with two branch warp yarns along the direction of the main warp yarns. The two branch warp yarns are spirally wound in opposite directions, and the branch warp yarns wrapped around two adjacent main warp yarns are staggered to form a tightly overlapped weaving structure.

[0007] Preferably, the fineness of the warp yarn is 1 / 3 to 1 / 2 of the fineness of the main warp yarn, and the warp yarn has at least one group of elastic yarns.

[0008] Preferably, the main weft yarn comprises a yarn core, which is formed by at least three vortex-spun yarns spirally wound around each other.

[0009] Preferably, the three vortex-spun yarns are nylon yarn, linen fiber yarn and acrylic yarn respectively, so as to enhance the structural strength of the yarn.

[0010] Preferably, the flax fiber yarn is formed by twisting two strands of flax fiber and one strand of elastic yarn.

[0011] Preferably, a wax emulsion core layer is provided at the center of the yarn core, and wax emulsion is injected into the wax emulsion core layer.

[0012] Preferably, the yarn core is wrapped with a wear-resistant layer to improve the wear resistance of the main weft yarn.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The denim fabric of the present invention has good wear resistance and washability because the warp yarns are wound along the main warp direction, and the adjacent warp yarns are interlaced with each other to form a tightly overlapped woven structure. In addition, large pores are formed between the adjacent main warp yarns, which has good air permeability and can also improve the softness of the fabric while maintaining the flatness of the fabric.

[0018] Example 1: A preferred embodiment of the present invention provides a vortex-spun soft denim fabric, comprising a main warp yarn 1 and a main weft yarn 2 interwoven with the main warp yarn 1, wherein each main warp yarn 1 is wound with two side warp yarns 3 along the direction of the main warp yarn 1, and the two side warp yarns 3 are spirally wound in opposite directions, and the side warp yarns 3 wound on two adjacent main warp yarns 1 are staggered to form a tightly overlapping woven structure, which has good wear resistance and water washability; and larger pores are formed between adjacent main warp yarns, which has good air permeability and can also improve the softness of the fabric while maintaining the flatness of the fabric.

[0019] Two strands of warp yarns 3 partially wrap around the interweaving nodes of the main warp yarn 1 and the main weft yarn 2; the fineness of the warp yarn 3 is 1 / 3 to 1 / 2 of the fineness of the main warp yarn 1, and the warp yarn 3 has at least one group of elastic yarns, which can provide elasticity and flexibility to the fabric.

The three vortex-spun yarns are nylon yarn, linen fiber yarn, and acrylic yarn, respectively, to enhance the structural strength of the yarn. The linen fiber yarn is twisted by two flax fibers and one elastic yarn, which can greatly reduce labor and reduce yarn hairiness.

Wax emulsion is an important additive for coating materials, which can significantly improve the softness, plasticity and feel of the yarn, and greatly increase the toughness of the yarn core 21.
