Abstract

The invention discloses a method for preparing a colored fabric containing polylactic acid fiber and silk components, which comprises the following steps of: dyeing polylactic acid fibers and silk fibers respectively, and weaving into the colored fabric. By the method, the respective advantages of the polylactic acid fibers and silk are fully exerted, high skin affinity is achieved, the cost of areal silk fabric can be reduced, and the prepared fabric has a wide market prospect.

Description

technical field [0001] The invention relates to a method for manufacturing colored fabrics containing polylactic acid fibers and silk components, belonging to the field of textiles. Background technique [0002] Polylactic acid fiber is a completely degradable green ecological fiber, which can be processed from starch-rich corn, cassava and other plants through fermentation, synthesis and spinning. Polylactic acid fiber has high strength, good skin affinity, antibacterial and flame retardant, good anti-ultraviolet performance, smooth and breathable, has a luster similar to real silk, and the price is only one-fifth of real silk. Moreover, the modulus of polylactic acid fiber is relatively high. The three Chinese patent applications whose publication numbers are CN101082153A, CN1010821154A and CN1651645A respectively disclose three dyeing processes of fabrics (fabrics) made of polylactic acid fibers, but when polylactic acid fibers are used as some fabric components, their h...
