Embodiment 1

[0031] A preparation method for textile high-strength hemp fiber, comprising the steps of:

[0032] S1. First immerse the hemp fiber in clean water for 1 hour, stirring continuously during this period, and take it out for later use;

[0033] S2, put the hemp fiber processed in step S1 into a steam explosion tank for steam explosion treatment, take it out after 3 minutes, then rinse the hemp fiber with deionized water once, and dry it for later use;

[0034] S3, putting the hemp fiber processed in step S2 into a corona treatment apparatus for corona treatment, and taking it out after 10 minutes for subsequent use;

[0035] S4. Weigh the following materials in corresponding parts by weight: 6 parts of dioctyl phthalate, 10 parts of lactic acid, 3 parts of alkyl silicone oil, 12 parts of sodium carboxymethyl cellulose, 40 parts of epoxy resin, 5 parts of fatty alcohol Polyoxyethylene ether, 3 parts of dodecyltrimethylammonium bromide, 50 parts of ethyl acetate, 8 parts of chitos...

Description

technical field [0001] The invention belongs to the technical field of textile fiber processing, and in particular relates to a preparation method of high-strength hemp fiber for textile. Background technique [0002] my country is the country with the most abundant hemp fiber resources. Since the international "hemp products fever" started in the early 1980s, it marked that the hemp textile industry has entered a prosperous period. At present, the production, processing and sales of hemp fiber and its products have occupied an important position in my country's national economy. There are more than 800 hemp textile, printing and dyeing enterprises in my country. The value of fixed assets exceeds 3 billion yuan, and the total demand for hemp fiber has exceeded 1 million tons. [0003] Hemp (Cannabis sativa L.) is an annual crop that was once an important fiber, oil, and food crop for humans. It originated in China or other countries in Central Asia. Then gradually spread ...
