Description

Technical Field

[0001] The utility model belongs to the technical field of textile fabrics and relates to a non-ammonia elastic fabric and clothing. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the functionality of clothing, so functional fabrics are becoming more and more popular, with a large demand and extremely broad market prospects. After the fabric is woven, it often needs to be dyed to meet the requirements of the fabric color and appearance, but the dyeing process will cause environmental pollution problems and may also damage the fabric fibers. Therefore, colored yarns are also used for weaving, so that the fabric has its own color and does not require a subsequent dyeing process. This can not only solve the above problems, but also shorten the production process of textiles.

[0003] After the fabric is woven, it is dyed. The dye is located on the outermost layer and is easily shed due to external forces or environmental influences. Therefore, the insufficient color fastness of the fabric has always been a problem for many fabrics. The color fastness of fabrics includes washing color fastness, dry and wet abrasion color fastness, light fastness, perspiration color fastness, sublimation color fastness, etc. Since the color fastness of fabrics is also an urgent problem to be solved, the use of colored yarn is one of the solutions.

[0004] In order to meet different dressing requirements, the requirements for fabric functionality will also be different. One of the important properties of fabric is elasticity. If the elasticity is poor, it will affect the comfort of wearing clothes. The main factor affecting the elasticity of clothing is the use of elastic fabrics. Currently, elastic fabrics generally include spandex. Although spandex has strong elasticity, it has problems such as difficulty in dyeing, excess elasticity, complex weaving, unstable fabric size, and easy aging during use. In addition, spandex generally needs to be made into a coated yarn before it can be woven on a machine, which increases the production cost. Therefore, sometimes other types of elastic yarns are needed to replace spandex.

[0005] CN 216885624U discloses an elastic breathable knitted fabric, which includes a breathable layer and a base layer, wherein the breathable layer includes elastic yarn and hygroscopic yarn, wherein the elastic yarn and hygroscopic yarn are weft-knitted to form a double-sided weft-knitted structure, wherein part of the coils of the elastic yarn and hygroscopic yarn periodically cross to the next row of coils by moving needles, and the coils of the elastic yarn and hygroscopic yarn move in opposite directions and form a plurality of rows of diamond meshes in the breathable layer. The fabric is woven with different yarns and forms meshes by moving needles to improve air circulation, but still requires subsequent dyeing steps, and the fabric structure is relatively complex, and there are many types of yarns, resulting in increased manufacturing costs.

[0006] CN 215209878U discloses a polypropylene elastic knitted fabric and clothing, the fabric comprises a ground yarn coil and a terry coil, the ground yarn coil is woven from elastic polyester into a plain weave structure, or the ground yarn coil is woven from elastic polyester and polypropylene into a plain weave structure, and the terry coil is woven from polypropylene into a terry structure. The elastic knitted fabric mainly uses elastic polyester to provide elasticity, but the elasticity of polyester is relatively weak, and polypropylene fiber is not easy to dye, so it is difficult to dye the fabric or directly make colored silk.

[0007] In summary, for spandex-free stretch fabrics, it is necessary to find elastic fibers or yarns to replace spandex, and at the same time use colored yarns to omit the subsequent dyeing steps, reduce production costs, and solve environmental pollution problems. Utility Model Content

[0008] In view of the problems existing in the prior art, the purpose of the utility model is to provide a spandex-free stretch fabric and clothing. The fabric is woven with colored yarn and does not require a subsequent dyeing process, thus avoiding the environmental pollution problem that may be caused by dyeing wastewater.
