Spinning technology

Abstract

The invention discloses a spinning process. The whole process flow includes: sequentially passing the combed waste through the cleaning process → carding process → drawing process → air spinning process; in the cleaning process, the combed waste is sequentially used by automatic Cotton plucking machine, first-level opener, second-level opener, vibrating box feeder, and single-hand lapping machine are processed to obtain combed noil fiber rolls; the rolled combed noil fiber rolls are carded Machine treatment to obtain cotton fiber slivers; the cotton slivers obtained in the drawing process are fed to the rotor spinning machine, and the cotton yarn products obtained by air spinning are fed to the cotton fiber slivers obtained in the carding process to be fed to the drawing frame to make cotton slivers. Feed to the rotor spinning machine; this process can effectively reduce fiber damage, less waste, high twist coefficient, uniform and stable cotton yarn product quality, and the strength value is about 8-10% higher than the existing technology.

Description

technical field [0001] The invention relates to the textile field, in particular to a spinning process. Background technique [0002] Cotton spinning is the process of spinning random short fibers of raw cotton into continuous cotton yarn or cotton blended yarn. Raw cotton enters the cotton spinning mill in the form of compacted cotton bales, and the fibers are in a blocky and disordered state, containing various impurities and defects. Therefore, in spinning, it is necessary to relax first and then assemble, that is, to break the unnecessary connection between fibers, remove impurities and defects, arrange them in the axial direction into yarns of required thickness, and twist them properly to form cotton yarns. The existing spinning process generally needs to go through main processes such as blowing, carding, drawing, roving, and spun yarn. The yarn and thread used for high-end products also need to increase the combing process. [0003] Due to the difference in the qual...

Problems solved by technology

[0003] Due to the difference in the quality of raw cotton and the parameters of the spinning process in the spinning process, the quality of the spinning products is often uneven. Process defects such as more noil, small twist coefficient and low strength value have a great impact on the quality of spinning products
