Problems solved by technology

[0003] With the continuous development of the industry, the market for fabrics is also expanding, but most of the fabrics have a single effect and only have the function of shielding. Different types of fiber blending are widely used in the textile field as a common method to improve fiber performance. The blending of fiber and high-performance fiber can not only expand the application field of natural fiber and increase the added value of natural fiber, but also an important means to improve the performance of high-performance fiber and reduce the price of high-performance fiber products

Embodiment Construction

[0013] Embodiments of the present invention: a method for producing a blended yarn of viscose fiber and hemp fiber with a flame-retardant effect, comprising the following steps:

[0014] (1) Preparation of hemp fiber: pre-clean the hemp fiber to remove surface impurities, perform 1 to 10 softening treatments, and dry to obtain softened hemp fiber; the softening treatment includes soaking the hemp fiber in In the pre-cooled softening treatment liquid, the softening treatment liquid contains alkali and urea or thiourea;

[0015] (2) Preparation of flame retardant viscose fiber: First, dissolve 5-10 grams of polyphosphate ester in 10-30 ml of N,N-dimethylformamide, and then add 6-12 grams of urea to prepare flame-retardant finishing solution, immerse 0.2 to 0.4 grams of viscose fiber in the flame retardant finishing solution, react at 130 to 150°C for 1 to 3 hours, and finally wash the viscose fiber to neutrality, and dry it in vacuum at 30 to 50°C for 1 ~12 hours to obtain flam...

Abstract

The invention discloses a production method of viscose fiber and hemp fiber blended yarn with a flame retardant effect. The production method includes the steps: (1) hemp fiber preparation; (2) flameretardant viscose fiber preparation; (3) blending. Compared with the prior art, the production method has the advantages that the blended yarn has moisture absorption and sweat releasing properties and excellent breathability and heat-conducting properties of hemp fibers, is cool to wear, does not stick to bodies and also has wearing comfort, flame resistance and the like.

Description

technical field [0001] The invention relates to the field of spinning, in particular to a method for producing a blended yarn of viscose fiber and hemp fiber with a flame-retardant effect. Background technique [0002] With the continuous development of science and technology, textile fibers that meet people's different needs emerge in an endless stream to meet the needs of consumers and play an increasingly important role in people's daily life. [0003] With the continuous development of the industry, the market for fabrics is also expanding, but most of the fabrics have a single effect and only have the function of shielding. Different types of fiber blending are widely used in the textile field as a common method to improve fiber performance. The blending of fiber and high-performance fiber can not only expand the application field of natural fiber and increase the added value of natural fiber, but also an important means to improve the performance of high-performance ...
