Real silk wool composite filament and preparation method thereof

Abstract

In order to overcome the defects of the prior art, the invention provides a real silk wool composite filament which comprises a wool yarn as a central core. More than eight cocoon filaments are adhered onto the outer side wall of the wool yarn. The content of the cocoon filaments is 25 to 40 percent. The real silk wool composite filament is prepared through a method comprising the following stepsof S1, selecting qualified cocoon materials; S2, stripping and selecting cocoons; S3, beating and picking ripe cocoons, extracting ripe cocoon filament heads, and adhering more than two ripe cocoon filament heads onto the wool yarn; S4, rotating the cocoon filaments adhered onto the wool yarn; twisting and sheathing the adhered filament threads; S5, inspecting the thickness of the twisted and sheathed filament threads; S6, drying the inspected filament threads for two times, spooling the dried filament threads onto a filament cylinder, and cutting to remove rough burrs during the spooling process. The real silk wool composite filament provided by the invention has the characteristics of wools and real silks, the occurrence of wind strands is avoided, and the later-period weaving cost is saved.

Description

technical field [0001] The invention belongs to the technical field of functional silk preparation, and in particular relates to a silk wool composite silk and a preparation method thereof. Background technique [0002] Silk generally refers to the spun yarn prepared by intertwisting silkworm cocoon silk, generally refers to mulberry silkworm cocoon silk. Silk is known as the "fiber queen", and has been favored by people throughout the ages for its unique charm. Silk is a protein fiber, and silk fibroin contains 18 kinds of amino acids that are beneficial to the human body. Based on the excellent properties of silk, silk is widely used in clothing, bedding and other fields. However, due to the poor warmth retention property of silk itself, silk blended fabrics with some properties of silk and other fabric properties were born. The existing silk wool composite yarn is generally combined and spun by the weaving mill, and its structure is generally as follows: figure 1 As s...

AI Technical Summary

Problems solved by technology

But this kind of yarn has the following disadvantages: the strength and elongation of real silk and wool yarn are different, that is, the strength of real silk is about 4 grams per denier, and the elongation is about 20%. Lower, therefore, it is easy to produce tight strands in the process of making fabrics

At the same time, under the same tension, this kind of strands is prone to the problem that one kind of strands will be straightened, and the other kind will be wrinkled or broken.
