Abstract

The invention relates to a preparation method for processing blended yarn A/B with a S/Z two-twist-direction structure through ring spinning equipment, and the blended yarn is preferentially used for developing a thermo-regulated product by combining the yarn structure characteristic. Fibers A and fibers B are subjected to opening, mixing and impurity removing, top making is conducted on a carding machine, doubling and drafting are conducted, rough yarn A and rough yarn B are processed, the rough yarn A is processed through a ring spinning frame, single yarn A in the Z twist direction is obtained, in the process of processing the rough yarn B into spun yarn, the single yarn A is output through a front roller and subjected to twisting through an S twist to be blended into yarn, and the Z/S two-twist-direction blended yarn A/B is formed. The blended yarn can be further matched with thermo-regulated fibers due to the unique appearance which is loose outside and tight inside, and the thermal insulation property of the product is improved from the structure improvement. Meanwhile, processing of the yarn breaks through the requirements of traditional spinning processing on the length and fineness of the fibers, and the spinning property of different fibers on current spinning equipment is greatly improved.

Description

A kind of double; two preparation twisted with the fingers to structure mixed yarn and heat-accumulation temperature-adjustment product thereof

Technical field

The present invention relates to and a kind of utilize the double; two new method twisted with the fingers to yarn texture of ring spinning apparatus exploitation, and use it for the preparation of heat-accumulation temperature-adjustment blending product。Relate in particular to a kind of be different from traditional list twist with the fingers to mixed yarn, but be structurally designed to Z sth. made by twisting/S sth. made by twisting and coexist in blended single yarn, in conjunction with the performance of thermo-regulated fiber itself, obtain outward appearance uniqueness, performance new structure yarn more preferably, can be applicable to the fabrics such as processing warming-type fabric。

Background technology

Traditional heat accumulation thermal is generally by the good fiber of warmth retention property effectiveness comparison own, and such as Pilus Caprae seu Ovis, the rabbit hair, doughnut etc., these fibers are typically all that the still air by clamping relatively more improves warming effect。At present, people require warming while, also pay close attention to its comfortableness, frivolous warming become a focus。Heat-accumulation temperature-adjustment to improve comfortableness for main purpose, it can the change of automatic sensing ambient temperature and Intelligent adjustment temperature, so when ambient temperature is relatively low, it is possible to temperature in automatic adjustment height clothes。Thus we can improve the warmth retention property of yarn by heat-accumulation temperature-adjustment。The method that heat-accumulation temperature-adjustment yarn realizes is usually pure spinning or blending, the method of blending has fiber to mix, bar is mixed, and some novel Yarn spinning methods such as SEILE textile, Seluofle such as spin at the mixing that can also realize different fiber, form the special yarn structure of similar strand or suitcase core。But according to tradition Spinning Principle, during blending, the length of fiber, fineness have certain requirement, its difference should be too not big, and this limits the blending of the bigger fiber of long difference in fiber fineness to a certain extent。Further, according to current spinning equipment, the sth. made by twisting of spun single thread to be S twist with the fingers or Z sth. made by twisting etc. single twist with the fingers to, its outward appearance smoother, structure comparison is tight, powerful high。But from the warmth retention property realized as improved yarn of some specific function, then can effect be general because of the fewer of air trapping。Double; two sth. made by twisting to mixed yarn, in outer pine tightly, its structure comparison is sparse, more air can be clamped between fiber in the yarn, the change auxiliary regenerator temperature-regulating fiber realizing utilizing yarn texture carrys out warming human body, while improving subsequent product warming effect, also it is expected to reduce the surface density of product, it is thus achieved that frivolous outward appearance。

Summary of the invention

It is an object of the invention to provide the new type yarn structure processing method that a kind of double; two sth. made by twisting coexists in single thread to structure。

Another object of the present invention is to the new method providing the change utilizing yarn texture to improve blending product heat-accumulation temperature-adjustment especially thermal property。

To heat-accumulation temperature-adjustment mixed yarn, double; two sth. made by twisting specifically provided by the present invention refers to that fiber A is thermo-regulated fiber, fiber B can be cotton fiber, wool fiber, it is also possible to is the functional fibre such as antistatic, uvioresistant, through the blended single yarn that blending is obtained。Wherein thermo-regulated fiber content is 25%～75%, and the content of fiber corresponds to 75%～25%。

Preparation method provided by the present invention refers to:

1. fiber A is after shredding, mixing and remove impurity, bar processed on carding machine。Pass through and close, drawing-off-rove-spinning process, obtain Z twist with the fingers to single thread A；

2. fiber B is after shredding, mixing and remove impurity, bar processed on carding machine。Through and close, after drawing-off-Roving Frames, obtain the rove B with a routing density；

3. on spinning frame, B rove being fed draw zone, single thread A is fed by front roller, after front roller exports, twists with the fingers to twisting resultant yarn through S。

Present invention have the advantage that

New type yarn structure preparation method provided by the present invention, gained yarn shape has shown as obvious bending, forms structure tight in outer pine, soft, good springiness。

Double; two sth. made by twisting provided by the invention, to heat-accumulation temperature-adjustment mixed yarn, not only has the double; two of uniqueness and twists with the fingers to structure, and have auxiliary regenerator temperature-regulating fiber and improve the function of product warmth retention property, be particularly suitable for the exploitation of frivolous warm-keeping type shell fabric autumn and winter。

Preparation method provided by the invention, fibre length and fineness can be identical, it is also possible to different, substantially increase different fiber spin ability on current spinning equipment。

Detailed description of the invention

By embodiment it will be further appreciated that the present invention, but embodiment can not limit present invention, and the preparation process described in embodiment and performance test are as follows:

Embodiment 1.
