Abstract

The invention discloses a high-density and high-proportion polyester blended fabric without PVA (polyvinyl alcohol) sizing slurry. The high-density and high-proportion polyester blended fabric withoutthe PVA sizing slurry consists of, by weight, the following raw materials of 43-47 parts of 309 environmentally friendly slurry, 61-64 parts of corn starch and 0.8-1.2 parts of smoothing agents, wherein the 309 environmentally friendly slurry consists of, by weight, the following raw materials of 80 parts of starch, 12 parts of acrylic acid, 6 parts of acrylamide, 0.5 part of itaconic acid, 1.5 parts of sodium hydroxide and 0.3 part of dibenzoyl peroxide. Through the cooperation of the slurry raw materials and the combination of the technology, the high-density and high-proportion polyester blended fabric without the PVA sizing slurry has the advantages of giving full play to the environmental performance of the pro-sizing 309 environmentally friendly slurry, and filling the gap in the field of domestic high-density and high-proportion polyester blended fabrics which do not use the PVA and polyester size.

Description

technical field [0001] The invention relates to the technical field of textile sizing, in particular to a PVA-free sizing method for high-density and high-ratio polyester blended fabrics. Background technique [0002] The society is developing and progressing. With the improvement of people's living standards, the need for environmentally friendly and non-polluting fabrics is constantly being demanded in the fields of clothing and home textiles, and the cost and environmental pressure of sewage treatment and discharge in the field of environmental protection are increasing day by day. [0003] At present, the general use of unclean sizing materials such as PVA and polyester, and the existence of high proportion polyester blended fabrics can only use PVA and polyester sizing materials with strong affinity for polyester as the main sizing material. To use, in order to meet the requirements of weaving. However, these main sizing materials require high desizing costs during the...
