Production technology of PTT fiber seamless knitted underwear with high wicking function

Abstract

The invention belongs to the field of functional knitted product production, and relates to a production technology of PTT (Polytrimethylene Terephthalate) fiber knitted seamless underwear with a high wicking function. The production technology comprises the steps that a PTT fiber with the crossed cross section and a bamboo carbon polyester fiber are taken as raw materials; two rough yarns and a double rough yarn feeding technology are adopted to manufacture a blended yarn; the blended yarn is knitted by a seamless knitting machine to form seamless knitted underwear grey cloth; and the seamless knitted underwear grey cloth is subjected to scouring and bleaching pretreatment, then dyeing treatment, and dehydration, drying, afterfinish and shaping treatment to from a PTT fiber seamless knitted underwear product with the high wicking function. The PTT fiber seamless knitted underwear with the high wicking function has the significant characteristics of moisture absorption, wicking, easiness in curing, bacteriostasis and the like; particularly, a wicking speed, the fastness to washing, the dimensional stability and the like of the product reach design requirements very well; and the design rationality of the product, the practicability of the product, the scientific rationality of the production technology and the significance of economic and social benefits are reflected.

Description

[0001] technical field

[0002] The invention relates to the production field of functional knitted products, in particular to a production process of seamless knitted underwear with high moisture-conducting PTT fibers. Background technique

[0003] Today's smoggy weather has made people feel the seriousness of environmental problems, and more people have joined the big team of environmental protection from all aspects. The country has also put forward higher requirements for the printing and dyeing industry, which is the most likely to cause environmental pollution in the textile industry, which has prompted the industry to enter a new era of pollution-free processing. From raw material selection to production and processing, the company strives to be pollution-free to the environment, and the products produced can better meet people's high requirements for health and environmental protection.

Embodiment 1

[0050] Such as figure 1 Shown, a kind of production technology of the PTT fiber seamless knitting underwear of high moisture-conducting function, comprises:

[0051] 1. Raw material selection

[0052] The cross-section PTT fiber produced by Donghua Haitian Company is used, the specification is 1.5dtex×38mm; the bamboo charcoal polyester fiber produced by Liaoyang Petrochemical Co., Ltd. is used, the specification is 1.67dtex×38mm.

[0053] 2. Preparation of blended yarn

[0054] The cross-section PTT fiber and bamboo charcoal polyester fiber have good length uniformity. The two are loosened, removed and fully mixed on the blowing line at a ratio of 40:60 to make a sliver. The fibers are fully mixed, and the two rovings are fed simultaneously in the spinning process, and finally the blended yarn of 18.2tex is obtained through automatic winding.

[0055] The technological process adopted is:
