Filter cartridge core suitable for cheese dyeing

Abstract

The invention relates to a filter cartridge core suitable for cheese dyeing. The filter cartridge core comprises a cartridge core and a filter screen, and the filter screen is arranged inside and / or outside and / or in the middle of the cartridge core. The filter cartridge core suitable for cheese dyeing can intercept undissolved residual particles of dye and auxiliaries in the dyeing process or oligomer particles generated in the dyeing process on the filter screen, so that the level-dyeing property of cheese dyeing is improved, color spots are reduced, and adhesion of oligomers on yarns is reduced; dyeing abnormity caused by the fact that dye liquor directly impacts on the yarn is avoided, and the yarn dyeing quality is improved.

Description

technical field [0001] The invention relates to the field of cheese dyeing, in particular to a filter core suitable for cheese dyeing. Background technique [0002] At present, in the printing and dyeing industry, the method of dyeing real silk, imitation silk, cotton yarn, polyester yarn and woolen yarn is to wind the yarn on the core to make a cheese, and the core is evenly processed with holes, and the cheese is placed Put the creel into the creel, and then put the creel into the dye vat for dyeing. When working, the dyeing liquid enters the yarn roll on the core through the hole on the core, thereby realizing the dyeing of the yarn. [0003] At present, in the dyeing process of polyester or other materials, because the dyes or auxiliaries are not uniformly dissolved in the chemical material, the direct contact with the yarn during the dyeing process will cause defects or color flowers; the oligomers produced in the polyester dyeing process will continue to Accumulation...

Problems solved by technology

[0003] At present, in the dyeing process of polyester or other materials, because the dyes or auxiliaries are not uniformly dissolved in the chemical material, the direct contact with the yarn during the dyeing process will cause defects or color flowers; the oligomers produced in the polyester dyeing process will continue to Accumulation in the yarn, causing defects or color patterns and affecting subsequent weaving
