Embodiment 1

[0077] The sizing process of the kapok or cotton blended yarn is as follows: sizing is carried out according to the following steps: 20% water is added in the sizing tank, and high and low speed agitators are started; then 0.5% talcum powder, Put 2.5% low-viscosity modified starch, 1.5% compound modified starch, and 0.5% polyacrylic acid into the pressure mixing tank: add 75% of the remaining water to correct the mixing volume, close the top cover of the pressure mixing tank; open The steam valve is heated, and when the temperature reaches 115°C, the steam inlet valve is automatically closed, and the pulp is stuffed, that is to say; among them:

[0078] Mixing temperature: When the temperature in the pressure mixing tank rises to 90°C, all the cold air in the barrel is exhausted, the high pressure is converted, and the exhaust valve is automatically closed. When the temperature in the barrel rises to 115°C, the intake valve is automatically closed. The pulping is completed;

Abstract

The invention provides a size mixing process of ceiba or cotton blended yarn. The method comprises the following steps: adding part of water in a size mixing cistern, starting a high-low-speed stirrer, and then placing talcum powder, low-viscosity modified starch, composite modified starch and polyacrylic acid slurry in a pressure size mixing cistern; adding the rest of water to adjust the size mixing volume, and fastening a top cover of the pressure size mixing cistern; and opening a steam valve for raising the temperature to 110-120 DEG C, automatically closing an admission valve, and smothering slurry. The experiment formula is prepared according to the characteristic of ceiba and cotton blended yarn, and the test on the performance of the formula slurry and sizing experiment are carried out. Results show that the technical formula of modified starch, polyacrylic acid slurry and a small amount of softening agent is adopted without using PVA completely to maintain the environment-friendly characteristic of ceiba. The test indexes of the formula are obviously superior to the prior art and worthy of being adopted.

Description

technical field [0001] The invention relates to a pulper for kapok or cotton blended yarn. Background technique [0002] The stamens of kapok are very good fabric materials. According to ancient books, "The kapok tree is two to three feet high. It is cut like paulownia wood. In February and March, the flowers will wither, and the core is cotton. They weave it into a blanket, which is as white as snow and extremely warm." Kapok fiber is a kind of single-cell fruit fiber, which is attached to the inner wall of the kapok capsule shell and is widely produced in subtropical regions. The uncompressed kapok fiber has a hollow rate as high as 97%, and the single fiber density can reach 0.30g / cm 3 . The fiber wall is thin, the wall thickness is uneven, the longitudinal surface has small convex marks, and there is no turning like cotton fiber. The head end of the fiber gradually becomes thinner, the tail end is thicker, and it is in a naturally closed state, and it is difficult for...
