Problems solved by technology

These three types of sizing have their own advantages and disadvantages: starch sizing has good adhesion to cotton fibers and is cheap, but the size film is brittle and has poor adhesion to chemical fiber blended yarns; polyacrylic sizing has good Adhesion, but its price is expensive and moisture absorption, so it can only be used as an auxiliary slurry; polyvinyl alcohol (PVA) is an excellent chemical slurry with high cost performance, but the desizing waste liquid cannot be biodegraded , the environmental pollution is more serious, so it is called "unclean slurry"
With the development of the differentiation of new fibers for spinning, multi-component blending, high-speed shuttleless looms, ultra-high branching and high-density woven fabrics, and green and clean products and the environment, the original The performance of combined slurry has been difficult to meet the production needs, especially in the development of combined slurry to replace PVA slurry has not yet made a breakthrough

Embodiment 1

[0027] Embodiment 1: The animal glue selected in this example is gelatin, the modified starch selected is cationic starch, and the high-efficiency auxiliary agent selected is fatty alcohol polyoxyethylene ether.

[0028] Preparation of modified animal glue:

[0029] The succinic anhydride activation method is used to activate polyethylene glycol, that is, monomethoxypolyethylene glycol and succinic anhydride are mixed in a molar ratio of 3:1, reacted at 37 ° C for 48 hours, and then the modified agent is mixed with gelatin in a molar ratio Mix 10:1, react at pH 7, 4°C for 60 minutes. High-efficiency column chromatography was used for product separation and purification.

[0030] High-performance slurry compounding: fully mix in a double-helix conical mixer according to the ratio of polyethylene glycol-modified gelatin: cationic starch: lauryl polyoxyethylene ether = 5: 85: 10 (percentage by weight), and pack the finished product.

[0031] The following performance tests were...

Embodiment 2

[0033] Embodiment 2: the selected animal glue of this example is bone glue, the selected modified starch is acetate starch, and the selected high-efficiency auxiliary agent is chitosan.

[0034] Preparation of modified animal glue:

[0035] N-hydroxysuccinimide activation method was used to activate polyethylene glycol, that is, monomethoxypolyethylene glycol and N-hydroxysuccinimide were mixed in a molar ratio of 3.2:1, and reacted at 25°C for 72 hours, and then Mix the prepared modifier with bone glue in a molar ratio of 9:1, react at pH 6.5 and 0°C for 45 minutes. High-efficiency column chromatography was used for product separation and purification.

[0036] High-performance slurry compounding: in double-helix conical mixer, modify bone glue by polyethylene glycol: acetate starch: chitosan (86.7% substitution degree, 1,000,000 molecular weight)=6: 89: 5 ratio (weight percent ) are fully mixed, and the finished product is packaged.

[0037] The following performance test...

Abstract

The invention discloses a high-performance and environment-friendly textile size and a preparation method thereof. By using the reactivity of activated polyethylene glycol, textile size is modified by animal glue and the modified animal glue is compounded with high-performance starch and a sizing assistant to develop the novel high-performance size capable of replacing dirty size polyethylene glycol size in the yarn sizing and weaving of cotton, viscose and blended yarn thereof. The size comprises the following components in percentage by weight: 5-10 percent of polyethylene glycol modified animal glue, 70-90 percent of modified starch and 5-25 percent of high-efficiency assistant. In addition, the size has excellent sizing fluid and sizing film performance and sizing performance.

Description

technical field [0001] The invention relates to the cotton textile industry, in particular to a high-performance textile slurry and a preparation method thereof. Background technique [0002] Sizing is a key process in the weaving engineering of the cotton textile industry, which directly affects the efficiency of looms and product quality. The size used in sizing is the basis for ensuring good sizing, and is the second most consumed material in textile production (the first is raw cotton yarn). The selection of suitable size for the production of different fabrics plays an important role in the economic benefits of enterprises. [0003] With the improvement of people's living standards, the development, diversification and environmental protection requirements of new textile fibers have higher and higher requirements for textile pulp. The textile size used in the world today can be divided into starch, polyvinyl alcohol (PVA) and polypropylene three major types of size, wh...
