Problems solved by technology

[0004] The present invention aims at the disadvantages of consumption of steam during back-drying of wet silk cakes, lower efficiency of tube-forming directly after back-drying, high waste silk rate, equal outer tubes of finished products, and low price, and provides a wet silk cake The silk cake is directly formed into a three-dimensional tube on the winding machine, and finally made into an embroidery thread

Embodiment 1

[0026] Example 1 Preparation of 120D embroidery thread

[0027] After the tidal cake meridian yarn machine is formed into a three-element tube, it is twisted to make embroidery thread;

[0028] In the process of forming the damp cake into a three-element tube on the meridian winding machine, the winding tension is controlled to the minimum tension required when the dry silk is formed into a three-element tube by the winder, that is, the tension regulator on the winding machine is used. The winding tension is set to 20g, and the broken wet silk is then formed into a ternary tube by a winding machine according to its standard tension value.

[0029] Place the ternary cylinders of dry silk and wet silk separately and enter the subsequent twisting process separately, that is, dry silk ternary twists together, wet silk ternary twists together, and finally 120D embroidery thread is made.

Embodiment 2

[0030] Example 2 Preparation of 120D embroidery thread

[0031] After the tidal cake meridian yarn machine is formed into a three-element tube, it is twisted to make embroidery thread;

[0032] In the process of forming the damp cake into a three-element tube on the meridian winding machine, the winding tension is controlled to the minimum tension required when the dry silk is formed into a three-element tube by the winder, that is, the tension regulator on the winding machine is used. The winding tension is set to 30g, and the broken wet silk is then formed into a ternary tube by a winding machine according to its standard tension value.

[0033] Place the ternary cylinders of dry silk and wet silk separately and enter the subsequent twisting process separately, that is, dry silk ternary twists together, wet silk ternary twists together, and finally 120D embroidery thread is made.

Embodiment 3

[0034] Example 3 Preparation of 120D embroidery thread

[0035] After the tidal cake meridian yarn machine is formed into a three-element tube, it is twisted to make embroidery thread;

[0036] In the process of forming the damp cake into a three-element tube on the meridian winding machine, the winding tension is controlled to the minimum tension required when the dry silk is formed into a three-element tube by the winder, that is, the tension regulator on the winding machine is used. The winding tension is set to 25g, and the broken wet silk is then formed into a ternary tube by a winding machine according to its standard tension value.

[0037] Place the ternary cylinders of dry silk and wet silk separately and enter the subsequent twisting process separately, that is, dry silk ternary twists together, wet silk ternary twists together, and finally 120D embroidery thread is made.

Abstract

The invention relates to a method for preparing embroidery threads by using wet spinning cakes which are formed by drying local parts in the production of viscose filaments. The wet spinning cakes form ternary cylinders through a filament winder, and then embroidery threads are formed through twisting. In the process that the wet spinning cakes form the ternary cylinders through the filament winder, the winding tension is controlled to be the minimum tension which is required when dry filaments form the ternary cylinders through the filament winder, and broken filaments are avoided. The method fully guarantees that the dry filaments and the wet filaments are classified into triads, the dry filaments and the wet filaments are formed independently, cost can be saved, consumption is reduced, product quality is effectively improved, and special drying treatment is not needed to be performed in advance, so consumption of energy resources is greatly reduced, additional value of a product is improved, and first-rate product yield is about 75 percent.

Description

Technical field [0001] The invention relates to a preparation method of embroidery thread, in particular, the invention relates to a process method for preparing embroidery thread by using moist cake formed by drying partial dead corners in viscose filament production. Background technique [0002] Viscose filament is a kind of viscose fiber, also called viscose fiber, rayon and ice silk. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber best meets the physiological requirements of human skin. It has the characteristics of smoothness, coolness, air permeability, antistatic, and brilliant dyeing. [0003] The so-called moist silk cake is a silk cake that is partially not completely dried during the drying process of viscose filaments, that is, the surface layer of the silk cake is dry and the middle and inner layers have local wet silk. At present, the wet cakes caused by the par...
