Abstract

The invention discloses a sizing process of a fine denier circular hole bright polyamide multifilament. By adjusting the technological parameters of four procedures such as warping, sizing, re-beaming and weaving, a good size film is formed on the surface of the fine denier circular hole polyamide filament and is convenient for weaving, the production efficiency is above 95% and a series of problems such as low weaving efficiency of multifilament woolen fabrics of fine denier circular hole bright polyamide multifilament series are solved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a sizing process for fine-denier round-hole bright nylon multifilaments. Background technique [0002] Fine denier nylon multifilament is more and more widely used in chemical fiber fabrics, and the requirements for fabric quality are getting higher and higher, especially the demand for fine denier glossy multifilament fabrics with round holes is more eager. As we all know, the quality of fine-denier glossy nylon multifilament fabrics with round holes is better, and the raw materials must be better first, but this is far from enough; if the production process cannot be smoothly produced, the weaving efficiency will not reach 95%, and the production cost is high, which cannot meet the modernization of enterprises. production needs. Fine-denier round-hole "●" nylon yarns are less likely to form a good size film than special-shaped cross-section "▲" nylon yarns. Without good size film forma...
