A kind of preparation method and its product of juxtaposed 8-shaped multi-dimensional crimp pa6/pa66 bicomponent fiber

Abstract

The invention discloses a preparation method of parallel 8-shaped multi-dimensional crimped PA6 / PA66 bicomponent fiber and its products, comprising: selecting PA6 slices as a raw material, and selecting PA66 as another raw material; the ratio range between PA6 and PA66 According to the mass ratio of 1:2~2:1; the two-component spinning is carried out through two screws, wherein the screw temperature of PA66 is set at 270~300°C, and the screw temperature of PA6 is set at 240~270°C to obtain POY Pre-drawn yarn; PA6 / PA66 two-component composite DTY fiber preparation: the prepared PA6 / PA66 two-component composite pre-drawn POY fiber is stretched through a texturing machine to obtain PA6 / PA66 two-component composite DTY fiber. The composite fiber of the present invention has a juxtaposed 8-shaped multi-dimensional crimped structure, and the prepared yarn has a cotton and wool feel, and the spun fabric has the style and comfort of a natural fabric, and at the same time has the aging resistance and non-mildew properties of chemical fibers. characteristic.

Description

technical field [0001] The invention belongs to the technical field of differential fiber preparation, and in particular relates to a method for preparing parallel 8-shaped multi-dimensional crimped PA6 / PA66 bicomponent fibers and a product thereof. Background technique [0002] The diversified design and comfort of fabrics have always been a persistent problem faced by chemical fiber fabrics. At present, there are some solutions such as blending or blending chemical fibers and natural fibers to prepare yarns or fabrics with natural fiber feel. To a certain extent, both comfort and product stability are taken into account, so there are more blended products on the market at present, but this kind of product has certain disadvantages. First, the amount of natural fiber added should not be too low. If it is too low, it cannot be achieved. The hand feeling of natural fibers, but if the addition amount is too high, there may still be mildew and other possibilities, which is not ...

[0002] The diversified design and comfort of fabrics have always been a persistent problem faced by chemical fiber fabrics. At present, there are some solutions such as blending or blending chemical fibers and natural fibers to prepare yarns or fabrics with natural fiber feel. To a certain extent, both comfort and product stability are taken into account, so there are more blended products on the market at present, but this kind of product has certain disadvantages. First, the amount of natural fiber added should not be too low. If it is too low, it cannot be achieved. The feel of natural fibers, but if the amount is too high, there may still be mildew and other possibilities, which is not conducive to the long-term preservation of fabrics; second, with the development of urbanization, the area of ​​cultivated land will decrease, and the output of natural fibers will be limited.
