Bulk yarn processing device and method

Abstract

The invention discloses a bulked yarn processing device and method, and the device comprises a yarn storage part which is used for storing yarns; the yarn expanding device comprises a first cavity, one end of the first cavity is provided with a yarn inlet, the other end of the first cavity is connected with a conical cavity, the end, away from the first cavity, of the conical cavity is a narrow end, and the narrow end of the conical cavity is provided with a yarn outlet. A spiral groove is formed in the inner wall of the first cavity and / or the conical cavity; the yarn feeding mechanism conveys the yarn from the yarn storage part to the yarn inlet; and the cheese winding equipment is used for receiving the yarns sent out from the yarn outlet and manufacturing the yarns into cheese yarns according to preset requirements. The bulking effect and the bulking uniformity are improved, and the step of preparing skein by reeling in an upstream supplier enterprise (such as a cotton spinning mill) in the prior art is omitted.

Description

Technical field [0001] The present invention involves the field of solid gauze and gauze technology, and especially involves a vertical gauze processing device and method. Background technique [0002] The vertical yarn is usually a gauze by two different contraction fibers, and then placed the yarn in steam, hot air or boiling water for swelling yarn treatment, so that the fiber with a high contraction rate has a large shrinkage, thereby thus, thereby therefore Get fluffy, plump, elastic pussy. Due to its unique bulk properties, the bulk gauze gives the clothing well in warmth and comfort. It has been widely used in the fields of clothing and decoration. There are two main problems in the current application of the vertical yarn: [0003] First, the yarn, the industry is called a solid gauze, the storage form is usually dominated by twisted yarn or tube gauze. The density of the tube gauze is large and the shrinkage space is small. The tube gauze cannot be directly completed. ...

AI Technical Summary

Problems solved by technology

[0006] The skeined yarn is directly expanded to form a bulked yarn, which cannot be wound into a bobbin by a winder for dyeing. The reason is that when the skeined yarn is used for puffing treatment, the skeined yarn is often hung in the puffing chamber, and the skeined yarn is affected by gravity. The shrinkage ratio of the upper and lower parts of the yarn is inconsistent, resulting in uneven yarn bulking and inconsistent density. The bulkiness of the bulked yarn obtained after bulking is uneven, and the product quality is defective. Therefore, cabinet dyeing vats or hank dyeing machines or Skeined yarn dyeing vat for dyeing (cabinet type dyeing vat as shown in Chinese patents CN210458602U and CN211171188U), the larger water flow of the cabinet type dyeing vat can improve the shortcoming of uneven yarn puffing, and the cabinet type dyeing vat is not suitable for environmental protection compared with the waste water of the drum type dyeing vat Require
