Embodiment Construction

[0024] A production process of elastic knitted fabrics, including raw material preparation → fabric arrangement → pre-shrinking process → dyeing process → softening treatment → dehydration → wet opening → shaping process → finished product inspection → packaging.

[0025] Raw materials are prepared by using Italian 28-needle 30″90F single-jersey circular knitting machine to weave the gray cloth containing PET / PTT composite fiber. Specifically, PTT / PET composite fiber can be used with different fibers such as cotton, nylon, viscose, tencel, and modal. Proportional implementation of mixed weaving and interweaving, the technical parameters of gray cloth weaving are: gram weight 75g / m 2 , door width 110×2cm polyester thread length: 26.5cm / 100G, yarn feeding tension: 2-3g.

[0026] Pre-shrinking process, pre-shrinking the gray cloth, using different shrinkage temperature sections to make the PTT and PET fibers in the PET / PTT composite fiber shrink to different degrees, forming a pe...

Abstract

A production process for an elastic knitted fabric includes the steps: (1) preparing raw materials by means of weaving gray cloth containing PET / PTT (polyethylene terephthalate / polytrimethylene terephthalate) composite fibers; (2) preshrinking the gray cloth, and differentially shrinking PTT fibers and PET fibers in the PET / PTT composite fibers by the aid of different shrinking temperature sections to form permanent three-dimensional spiral rolls and generate elastic effects; (3) dyeing the gray cloth by means of slowing down temperature rise and drop to ensure uniform heat shrinkage of the fabric; (4) softening the gray cloth by the aid of treatment fluids containing hydrophilic silicone oil softeners and moisture absorption sweat removal auxiliaries; and (5) setting the gray cloth by the aid of a setting machine with setting fluids containing hydrophilic silicone oil softeners and moisture absorption sweat removal auxiliaries. The fabric produced by the process is excellent in elasticity, elastic in recovery, soft in hand feeling, rapid in moisture absorption, fine in dryness, anti-fouling, fluffy, sunlight-resistant and chlorine-resistant, and some weaknesses and shortcomings of a common elastic fabric in production and application can be overcome.

Description

technical field [0001] The invention relates to a production process of elastic knitted fabric. Background technique [0002] With the continuous improvement of consumer grades, consumers are increasingly demanding the flexibility of uniforms. The most widely used elastic yarn in the world today is spandex. Its superior elasticity cannot be replaced by other yarn products. However, spandex has disadvantages such as high price, large production investment, complex spinning process, high consumption, fear of chlorine bleaching in finishing, poor shaping, unstable elasticity, difficult care, easy foaming, excess elasticity, and weariness. PTT fiber is a new type of polyester fiber, which has the characteristics of polyester, nylon, and acrylic fiber. In addition to good antifouling performance, it is also easy to dye, soft to the touch, and full of elasticity. Compared with spandex, it is easier to process and is very suitable for textile and garment fabrics. However, since ...
