Warp sizing method and application thereof

Abstract

The invention discloses a warp sizing method and an application thereof. The warp sizing method includes the following steps: preparing sizing agents, boiling the sizing agents, foaming, conducting foam sizing, rolling the sizing agents, drying and leasing; foaming ratio and applying amount are controlled by a foam producer in the step of foaming; the foaming ratio is 1:3-30, and the applying amount is 10%-50%; foam formed by the foam producer is instantly and entirely applied to warp yarn through a foam applicator in the step of conducting foam sizing; and the foam applicator is divided into an upper applying head and a lower applying head. The warp sizing method has the advantages of being low in water consumption, little in chemical and wastewater discharge, little in sizing amount, easy to desize, short in yarn drying time, capable of saving energy consumption by 50%-60%, high in production speed, low in cost, continuous in foam applying mode, capable of ensuring uniformity and stability of the applied foam, low in product breakage rate, high in efficiency and good in weaving effect.

Description

Technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a warp sizing method and its application. Background technique [0002] As we all know, the warp yarn needs to be sizing before the yarn is woven. The purpose of warp sizing is to lay down the hairiness, improve abrasion resistance, ensure that the warp has a certain strength and elasticity, and reduce the rate of breakage during weaving. The traditional warp sizing process is as follows: the warp is first dried by a drying cylinder to remove the moisture content of the yarn, then enters the high-temperature size tank, and is squeezed by the roller. On the one hand, the size is penetrated into the yarn and fiber, and the roller is used on the other The pressure makes the excess size squeeze out, and finally the yarn is dried by the drying cylinder to complete the sizing process. Generally speaking, the traditional padding sizing method uses water as a medium to ...

Problems solved by technology

Research on this technology began in the 1970s and 1980s, but so far this technology has not been well applied

The key is that the foam is a metastable system. After the foam is produced, if it cannot be used immediately, the foam will expand, merge and rupture over time, which will lead to unevenness of the size applied to the yarn. and inconsistency, resulting in the inability to stabilize production
