High counts high blending ratio silk/flax scribbled and its preparation

Abstract

The invention relates to a high branch high mixed weaving ratio silk / flax blending yarn that belongs to weaving field. The blending yarn is made up from flax fiber that the splitting degree is over 2000 and silk by the method of dry mixed weaving technology. The ratio of silk and flax is 40-90:60-10. The key point of the blending yarn is the preprocessing to the flax material that improves the splitting degree but does not change the feature of it, and the splitting degree improves from 400-600 to 2000, the holding capacity is enhanced, and the spinnability is improved as well. The dry spinning method is adopted, the silk content is high in the blending yarn and the comfort of the cloth is sharply increased.

Description

technical field [0001] The invention relates to the textile field, relates to a blended yarn of flax fiber and silk, and also provides a preparation process of the blended yarn. technical background [0002] Chinese patent 95102364.0 discloses a blending process of flax and silk. This process adopts the linen spinning production line (wet spinning), that is, the flax is first made into flax strips, then mixed with silk fibers, and then combed by several needles to make a tube. Load the roving, then place the roving in a high-pressure box for strong chemical degumming, bleaching, and finally wet spinning to obtain blended yarn. In the current wet spinning process of flax yarn production, through the re-selection of the process parameters of roving degumming and bleaching, the color of the thick, hard and dark flax fiber mixed with the soft and white silk fiber is close to that of respinning. into yarn. There are many deficiencies in this process, which are shown in: 1) Beca...

AI Technical Summary

Problems solved by technology

There are many deficiencies in this process, which are shown in: 1) Because the wet strength of flax fiber is stronger than dry strength, and the dry strength of silk fiber is stronger than wet strength, and the wet spinning process is only suitable for pure flax spinning. The strength of silk is reduced, and the silk fibers stick together after being exposed to water and are not easy to be drawn, and it is difficult to form a yarn. Therefore, the proportion of silk in the silk-linen blended yarn cannot exceed 15%, and it is difficult to reflect the style characteristics of silk: 2) Linen After the fiber and silk fiber are mixed into roving, chemical degumming and bleaching are carried out in a high-pressure box, which will greatly damage the silk fiber (protein fiber), easily denature the silk fibroin and turn yellow, and reduce the wearability of the fabric; 3) because the flax fiber The split degree is only 400-600, the fiber is thick and hard, the cohesion is poor, and the spinning count is low, generally not more than 60 N
