Method for controlling foreign matter in raw yarn and method for determining the amount of foreign matter in raw yarn

Abstract

The invention discloses a method for controlling base yarn foreign fibers and a method for determining the quantity of the base yarn foreign fibers. The method for controlling the base yarn foreign fibers includes the steps that the base yarn foreign fibers are pre-sorted; the pre-sorted base yarn foreign fibers are manually sorted; the base yarn foreign fibers left after manual sorting are sorted through a foreign fiber machine; the base yarn foreign fibers left after sorting through the foreign fiber machine are sheared through a winding machine. The method for determining the quantity of the base yarn foreign fibers includes the steps that after the base yarn foreign fibers are pre-sorted, the pre-sorting quantity of the base yarn foreign fibers is obtained; after the pre-sorted base yarn foreign fibers are manually sorted, the manual sorting-out quantity is obtained; after the base yarn foreign fibers left after manual sorting are sorted through the foreign fiber machine, the sorting-out quality of the foreign fiber machine is obtained; after the base yarn foreign fibers left after sorting through the foreign fiber machine are sheared through the winding machine, the shearing quantity of the winding machine is obtained; the remaining base yarn foreign fiber quantity is obtained by subtracting the manual sorting-out quantity, the sorting-out quantity of the foreign fiber machine and the shearing quantity of the winding machine from the pre-sorting quantity of the base yarn foreign fibers. The base yarn foreign fibers can be effectively controlled, and the remaining base yarn foreign fiber quantity is accurately calculated.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for controlling foreign fibers in raw yarns and a method for determining the amount of foreign fibers in raw yarns. Background technique [0002] The yarn quality of cotton yarn directly affects the weaving efficiency and product quality of the cloth factory, and also determines the customer's acceptance of the product. Cotton yarn contains other foreign fibers, which will bring great harm during the weaving and dyeing process. It will not only reduce the quality of the product, but also increase the extra repair work and affect the production efficiency. Usually cellulose fibers (cotton fiber, bamboo fiber, etc.) mostly use reactive dyes and direct dyes; chemical fiber fibers (polypropylene, polyester, vinylon, spandex, etc.) use disperse dyes and cationic dyes; protein fibers (wool, silk etc.) are acid dyes and acid mordant dyes; depending on the molecular structure ...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no effective control and algorithm for the number of foreign fibers in the textile industry. The conventional method is to adjust and control the number of foreign fibers according to customer feedback. Up to the standard, no detailed calculation and prediction was carried out in this process control, and the information on the number of foreign fibers on the cloth surface lagged behind, resulting in serious losses
