And (3) comprehensively evaluating each group of fabrics by 7 quality inspectors in the modes of touching, pinching, rubbing, grabbing, shaking, pulling and the like, grading the fabrics mainly from the aspects of smooth softness, fluffy stiffness, elasticity and recovery degree, and then averaging and equally dividing the fabrics into A, B, C, D four grades, wherein A is the best.

4. Abrasion resistance of fabric

The abrasion resistance of the fabric was tested according to the astm d3884 abrasion resistance test method, and the results are expressed as abrasion resistance times.

5. Quality evaluation of functional fiber

Defects including abnormal fibers such as stiff yarns, doubled yarns, stiff yarns, head injection yarns, rubber blocks and the like appear in the production process of the composite fibers, the quality of each group of the composite fibers is judged by 7 quality inspectors according to conventional experience with a monthly period and is scored, and then the fibers are divided into three grades of excellent, good and qualified by averaging.

The results are shown in Table 2.
