Multi-color grid-connected processing technology of mulberry silk

Abstract

The invention discloses a multi-color network combination processing process for mulberry silk and belongs to the technical field of mulberry silk materials. The processing process includes: degumming, wherein the specification of the to-be-degummed mulberry silk is 23dtex raw mulberry silk f1*5 380twist / meterS, the degumming includes semi-degumming and biological enzyme processing which are performed on a cone dyeing machine, the components of the semi-degumming include a refining agent with the mass concentration being 2g / L and sodium carbonate with the mass concentration being 1g / L, the bath ratio is 1:18, semi-degumming temperature is 95 DEG C, and semi-degumming time is 30 minutes; the biological enzyme processing uses silk liquid protease with the activity being 16.0KNPU / g and the mass concentration being 4g / L, biological enzyme processing temperature is 45 DEG C, and biological enzyme processing time is 90 minutes; dyeing; spooling; performing network combination, wherein threeboiled-off mulberry silk of different colors are subjected to network combination on a network combination machine, processing speed is 800rpm, nozzle air pressure is 0.3MPa, network tension is 14CN,and the three-color network silk with 2 network nodes per centimeter and the specification being 23dtex boiled-off colored mulberry silk f1*5 380twist / meterS*3 is obtained after the network combination. By the processing process easy in processing, the obtained mulberry network silk is small in strength loss.

Description

【Technical field】 [0001] The invention relates to a multi-color grid-connected processing technology of mulberry silk, which belongs to the technical field of mulberry silk materials. 【Background technique】 [0002] Polyester network technology is relatively mature and has strong processability. This is due to the hot-melt properties of polyester filaments. At a certain temperature, the filaments are blown and twisted by high-pressure airflow, and the yarns are easy to knot and form network nodes. However, mulberry silk Grid connection is difficult to process. If the temperature is too high, it will easily turn yellow, making the color of the silk uncontrollable. It will also cause silk brittleness, affect the smooth weaving, and the broken yarn rate is serious. If the temperature is too low, it will be difficult to achieve grid connection; if the airflow pressure is too high, Silk is easy to blow and cause its disorder, resulting in uneven network, too small air pressure wi...
