Problems solved by technology

[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.

Abstract

The invention discloses a preparation method of parallel 8-shaped multi-dimensional crimped PA6 / PA66 double-component fibers and a product thereof. The preparation method comprises the following steps: PA6 slices are selected as one raw material, and PA66 is selected as the other raw material, wherein the mass ratio of the PA6 to the PA66 is 1: 2-2: 1; two-component spinning is carried out throughtwo screws, the screw temperature of the PA66 is set to be 270-300 DEG C, the screw temperature of the PA6 is set to be 240-270 DEG C, and POY pre-drawn yarn is prepared; and preparation of the PA6 / PA66 two-component composite DTY fiber is achieved: the prepared PA6 / PA66 two-component composite pre-drafted POY fiber is elasticized through an elasticizer to prepare the PA6 / PA66 two-component composite DTY fiber. The composite fiber is of a parallel 8-shaped multi-dimensional crimped structure, the hand feeling of the prepared yarn is cotton feeling and wool feeling, and the spun fabric has thestyle and comfort of a natural fabric and also has the characteristics of aging resistance and mildew resistance of chemical fibers.
