Process for producing high-grade weaving yarns with heavy weight per unit of card silver in a carding machine from Zhengzhou Textile Machinery Co., Ltd

Abstract

A process for producing high-grade weaving yarns with heavy weight per unit of card silver in a carding machine from Zhengzhou Textile Machinery Co., Ltd relates to the textile technical field, in particular to a process for producing high-grade weaving yarns. The process includes: ZTM blowing-carding process- pre-drawing- lap drawing- combing- drawing (with auto leveling) - roving- cheese winding -bale packing- yarn sales. Under the circumstance of constant card clothing of the carding machine, the linear weight of card silver can be increased to 21g / 5m increased by nearly 17 percent by, increasing the RPM of cubing rolls, cylinders and cover plates, blocking up a support trunnion for feed roller and reducing the spacing between the feed roller and the cubing roll, thus not only increasing the production efficiency and saving the energy consumption but also addressing the problem of dissatisfaction with the supply of card silvers.

Description

Technical field: [0001] The invention relates to the technical field of textiles, in particular to a production process for high-grade woven yarns, in particular to a process for quantitatively producing high-grade woven yarns from raw sliver weights of a blowing and carding machine combined with a carding machine of Zhengzhou Textile Machinery Co., Ltd. Background technique: [0002] The composition of the blowing-carding unit of Zhengzhou Textile Machinery mainly plays the four major functions of opening, impurity removal, mixing, and uniformity. The component combs and loosens cotton fibers into single fibers, laying the foundation for subsequent combing, impurity removal, and drafting. It is called the "heart" process of spinning. The quality level of semi-finished products in the carding process directly determines the final product quality. Yarn quality level. Generally, it is feasible to use high-efficiency technology to spin medium and low-grade yarns below 40 count...

AI Technical Summary

Problems solved by technology

Some manufacturers use a slightly heavier basis weight, which is about 18g / 5m, but after the weight is increased, the amount of fiber processed by the carding machine per unit time increases, the carding degree of the fiber becomes worse, and the neps and coarse details of the yarn are obviously deteriorated.

However, in order to meet the needs of the market, the average yarn count produced in the workshop is obviously thicker than the original design. If the quantitative production is still carried out according to the original design, the supply of raw sliver will be out of touch, forcing 10 spinning frames to stop for more than 12 hours a day, seriously affecting production efficiency.
