Problems solved by technology

[0005] The present invention provides a novel starch-type sizing agent for the problems that the existing starch-type sizing agent cannot effectively solve the problems such as the low start-up rate and full package rate of the product, the high hairiness rate of the bobbin yarn, and the warping easily broken yarn. The electronic grade spun yarn produced has the advantages of high start-up rate, high yarn breaking strength, moderate softness and hardness, low bobbin hairiness rate and less end breakage in the warping process, etc.

Embodiment 1

[0028] The starch-type sizing agent used in the production of electronic-grade spun yarn is composed of the following proportioning raw materials (the proportioning ratio of raw materials is the percentage by weight of the sizing agent:

[0029]

[0030]

[0031] The wire drawing process used in this experiment is 1200-1600 hole platinum-rhodium alloy bushing wire drawing. The final raw wire is made of 150-400 monofilaments. The diameter of the single fiber is controlled at 7-9 microns, and the weight of the raw wire is 6-8kg, the conditioning process is 23-25°C, the relative humidity is 55-65%, and the conditioning time is 7.5 hours.

Abstract

The invention discloses a starch type impregnating compound for electronic grade spun yarns. The impregnating compound is prepared from the following components in percentage by weight: 1.5-4.5 percent of etherified high amylase corn starch with amylose content of 55-70 percent, 1.0-4.0 percent of etherified low amylase corn starch with amylose content of 27-30 percent, 0.10-2.00 percent of hydrogenated cottonseed oil, 0.05-0.80 percent of emulsifier, 0.10-2.00 percent of lubricant, 0.001-0.005 percent of antibacterial agent, and the balance of deionized water. The electronic spun yarns produced by the impregnating compound has the advantages of high operation rate, high yarn breaking strength, proper hardness, low hairiness rate of bobbin yarns, few broken ends in the warping process and the like.

Description

(1) Technical field [0001] The invention relates to a starch type sizing agent for electronic grade spun yarn. (2) Background technology [0002] Starch-type sizing is a kind of textile-type sizing commonly used in the world's glass fiber industry. Since the establishment of the glass fiber industry in the 1930s, the technology of starch size in the cotton spinning industry has been used for reference to develop glass fiber sizing. After several After ten years of continuous improvement and improvement, the technology of starch-based sizing agent has reached a fairly advanced and perfect level. Especially in the United States, Japan, and Western Europe, it is widely used in the production of glass fiber for textiles. [0003] Starch sizing has a good protective effect on glass fiber bundles, and the yarn breaking strength is higher. Its raw materials are non-toxic and non-irritating to the human body. The main advantages are easy thermal cleaning, low decomposition temper...
