Abstract

The present invention relates to Newdal fiber underwear fabric, and is characterized in that the present invention is composed of raw materials having the following weight percentages: 45 percent to 52 percent of Newdal fiber, 45 percent to 52 percent of cotton fiber, and 3 percent to 8 percent of Lycra elastic fiber. The processing craft is that the Newdal fiber and the cotton fiber are firstly blended for spinning, and then are interwoven with the Lycra elastic fiber, so as to make the underwear fabric. The present invention has the advantages of better gloss, skin-friendly property, smooth hand feeling and comfortable flexibility.

Description

A kind of Newdal fibre inner wear face fabric and processing technology thereof

Technical field

The present invention relates to a kind of Newdal fibre inner wear face fabric and processing technology thereof, belong to textile technology field.

Background technology

Along with the raising of people's living standard, the requirement that is used to make underwear fabric is had higher requirement, not only require durablely, and require to have gloss preferably, good skin-friendly and comfortable flexibility.

At present, the underwear fabric of selling on the market, though can satisfy people's requirement in some aspects, but,, how the performance of various fibers is maximized favourable factors and minimized unfavourable ones along with the today of weaving and continuing to bring out with new material, improve the scientific and technological content of lining, the scientific and technical innovation work that active response country advocates increases economic benefit and social benefit, has profound significance.

The conventional used raw material of underwear fabric of producing is the multicomponent fiber yarn that chemical fibre such as natural fabric such as cotton, wool and terylene, viscose, model, sky silk and these fibers form by a certain percentage.Their shortcoming is: natural fabrics such as cotton, wool are subjected to ploughing, and natural resources restricts and the environmental protection Isoquant can not effectively amplify and the price of wool grows to even greater heights; Terylene is higher to the reliability of oil; The wet brute force of viscose is lower; The serious dependence on import delivery cycles of regenerated fiber such as model, day silk are long, and price is higher and supply is nervous.

The conventional spinning method of producing the used yarn of underwear is a RING SPINNING, and its shortcoming is that the filoplume of yarn is more, and single thread force is relatively poor relatively, and yarn unevenness is relatively poor.

Summary of the invention

The purpose of this invention is to provide a kind of Newdal fibre inner wear face fabric and processing technology thereof with better gloss, skin-friendly, smooth hand feeling and comfortable flexibility.

For realizing above purpose, technical scheme of the present invention provides a kind of Newdal fibre inner wear face fabric, it is characterized in that, is made up of following raw materials by weight percent: Niu Daier fiber 45%-52%, cotton fiber 45%-52%, Lycra elastomer 3%-8%.

Said Niu Daier fibre number is 0.9-1.7dtex, and length is 30-45mm; Said Lycra elastomer is 30D-40D;

A kind of processing technology of Newdal fibre inner wear face fabric is characterized in that, comprises the steps:

The first step. the Niu Daier fiber is spinned into siro-spinning yarn with cotton fiber, and yarn count props up for 32-40 English, and the twist of spinning is 80-90 sth. made by twisting/10cm.

Second step. weave: siro-spinning yarn and Lycra elastomer are adopted the knitting woven Newdal fibre inner wear face fabric of weft knitting circle latitude, and its technological parameter is as follows:

The plane No. of loom: 24G-28G;

Loop length: match network spinning mixed yarn 30-32cm/100 pin; Lycra elastomer 10-11cm/100 pin.

Said weft knitting circle latitude knitting machine is single-side machine or two-sided machine, and the structure of the knitting underwear fabric that goes out is single knitting lining or two-sided knit fabric.

It is the brute force that strengthens yarn that the present invention selects the purpose of match network spinning for use, greatly reduces the filoplume of yarn, and bar is done more even.

Owing to should embody gloss, feel and the draping property of Niu Daier, give prominence to the comfort properties of cotton fiber and the brute force of enhancing yarn again, the twist of strict control spinning in spinning process, generally be controlled at 80-90 sth. made by twisting/10cm, the twist is low excessively, influences the brute force and bad, the no sclerotin feel of gloss of yarn; The twist is too high, and the skew that is prone to broken hole and cloth cover in weaving process increases.

Advantage of the present invention is to have better gloss, skin-friendly, smooth hand feeling and comfortable flexibility.

The specific embodiment

The invention will be further described below in conjunction with embodiment.

Embodiment

Newdal fibre inner wear face fabric is to be interweaved by match network spinning mixed yarn and Lycra elastomer with constituting, and the percentage by weight of various raw materials is in the lining:

Said Niu Daier fiber is to obtain the raw material from reproducible high-quality cotton/wooden oar, it is the cellulose fibre that has than high wet modulus, performance is near the Lenzin model, fiber number is 1.33dtex, length is 38mm, true qualities adopt the Niu Daier fiber of Shandong Hailong Co., Ltd., and ratio is 48.5%;

Cotton fiber is selected conventional combing cotton fibre for use, and ratio is 48.5%;

Said 30D Lycra elastomer adopts former du pont company now to be the Lycra elastomer of English Radar Audio Company, and ratio is 3%; Said cotton fiber is that cotton fiber is produced in Shandong;

Niu Daier/cotton siro-spinning yarn is fit to single-side machine or two-sided woven making, and the loop length of rationally controlling every kind of yarn count is the key that guarantees this lining feel, comfortable flexibility, and reasonably adjustment method is to improve the powerful guarantee of bad cloth quality.

A kind of processing technology of Newdal fibre inner wear face fabric comprises the steps:

The first step. the Niu Daier fiber is spinned into siro-spinning yarn with cotton fiber, and yarn count is that 40 English prop up, and the twist of spinning is 85.2 sth. made by twisting/10cm;

Second step. weave: siro-spinning yarn and Lycra elastomer are adopted the knitting woven Newdal fibre inner wear face fabric of weft knitting circle latitude, and its technological parameter is as follows:

Adopt the knitting two-sided machine of weft knitting circle latitude, technological parameter is as follows:
