Sizing-free environment-friendly elastic fabric and production process thereof

Abstract

The invention discloses a sizing-free environment-friendly elastic fabric and a production process thereof. The sizing-free environment-friendly elastic fabric comprises a fabric body, the fabric bodyis a machine knitting fabric woven by warp yarns and weft yarns, the warp yarns of the fabric body are sizing-free cotton yarns, the weft yarns of the fabric body are elastic composite yarns, two sizing-free single yarns are core spun yarns and twisted to form the sizing-free cotton yarns, the sizing-free single yarns take carbon fiber filaments as core yarns and combed cotton fibers as wrappingfibers, the combed cotton fibers spirally wrap the carbon fiber filaments, the elastic composite yarns include spandex yarns and bamboo pulp fiber vortex spun yarns, and both the warp density and theweft density of the fabric body are smaller than 600 pieces / 10 centimeters. According to the fabric, the yarns are improved, a novel yarn structure is adopted, the process can be applicable to manufacturing of machine knitting fabrics with various texture structures, sizing is omitted, and environmental friendliness is good.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a size-free environmentally friendly elastic fabric and a production process thereof. Background technique [0002] In addition to network yarn, twisted yarn, and untwisted yarn (combined with a polyvinyl alcohol water-soluble yarn), other warp yarns (filaments) need to be prepared by sizing to reduce hairiness, wear or breakage of the yarn. This is because during the weaving process, the yarn is subject to friction from healds, steel buckles or other parts, and hairiness will be generated on the surface. The yarn is prone to breakage during the weaving process. Generally, before the yarn is weaved in the textile process, a layer of size is applied to the surface of the single yarn through the sizing process to protect the yarn from hairiness and enhance the friction resistance. At the same time, after the weaving is completed, the size on the surface of the single yarn needs to be remov...

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a size-free environmentally friendly elastic fabric and its production process. By improving the yarn and weaving the size-free yarn into a size-free fabric with weft elasticity, the current problem is solved. Some fabrics need to be sizing, which consumes a lot of energy and water resources, and also produces a lot of waste water, which is a big problem of environmental pollution.
