Problems solved by technology

[0007] In the traditional production method of strong twisted yarn or the direct secondary twisting process of ordinary twisted yarn, the inventors found that problems such as yarn breakage, fabric hairiness and unstable quality of strong twisted yarn are very easy to occur, resulting in waste and poor product quality. Can not meet production requirements

Embodiment 1

[0018] A production process of strong twisted yarn with stable twist, comprising the steps of:

[0019] (1) Put the ordinary twisted yarn in the mixed solution of cellulase and alkaline xylanase, soak it at 55°C for 1 hour, perform ultrasonic vibration treatment at the same time, dehydrate and dry after washing; the step (1) Cellulase 2.5g / L, alkaline xylanase 6g / L. The frequency of the ultrasonic wave in step (1) is between 45kHz; the cleaning solution is an aqueous solution containing hydrogen peroxide. The common twist yarn is 60 cotton yarns, and its twist range is normal weaving twist.

[0020] (2) Carry out secondary twisting to the ordinary twisted yarn after the treatment of step (1) with a short fiber two-for-one twisting machine, and the twisting range of the secondary twisting increase is 500 twists per 10 centimeters.

[0021] (3) Treat the yarn obtained in step (2) with liquid ammonia. The treatment process is as follows: the temperature of liquid ammonia is -15...

Embodiment 2

[0024] A production process of strong twisted yarn with stable twist, comprising the steps of:

[0025] (1) Put the ordinary twisted yarn in the mixed solution of cellulase and alkaline xylanase, soak it at 50°C for 2 hours, perform ultrasonic vibration treatment at the same time, dehydrate and dry after washing; step (1) Cellulase 2.0g / L, alkaline xylanase 8g / L. The frequency of the ultrasonic wave in step (1) is between 60kHz; the cleaning solution is an aqueous solution containing hydrogen peroxide. The common twisted yarn is an 80-count viscose yarn, and its twist range is normal weaving twist.

[0026] (2) Carry out secondary twisting to the ordinary twisted yarn after step (1) treatment with short fiber two-for-one twisting machine; Step (2) described secondary twisting increases twist range and is every 10 centimeters 400 twists.

[0027] (3) Treat the yarn obtained in step (2) with liquid ammonia. The treatment process is as follows: the liquid ammonia temperature is...

Embodiment 3

[0030] A production process of strong twisted yarn with stable twist, comprising the steps of:

[0031] (1) Put the ordinary twisted yarn in the mixed solution of cellulase and alkaline xylanase, soak it at 65°C for 0.5h, carry out ultrasonic vibration treatment at the same time, dehydrate and dry after washing; Said cellulase 3.0g / L, alkaline xylanase 5g / L. The frequency of the ultrasonic wave in step (1) is between 30 kHz; the cleaning solution is an aqueous solution containing hydrogen peroxide. The common twisted yarn is 16 counts of cotton and viscose blended yarn, and its twist range is normal weaving twist.

[0032] (2) Carry out secondary twisting to the ordinary twisted yarn after step (1) treatment with short fiber two-for-one twisting machine; Step (2) described secondary twisting increases twist range and is every 10 centimeters 600 twists.

[0033] (3) The yarn obtained in step (2) is subjected to liquid ammonia treatment. The treatment process is as follows: th...

Abstract

The invention discloses strong twisted yarn with stable degree of twist and a production technology of the strong twisted yarn. The strong twisted yarn comprises the following steps that 1, common twisted yarn is placed into a mixed solution of cellulose and alkaline xylanase, is subjected to soaking treatment at 50-65 DEG C for 0.5-2 h, is subjected to ultrasonic oscillation treatment at the same time, and is dehydrated and dried after being washed; 2, a short fiber two-for-one twister is adopted to secondarily twist the common twisted yarn treated in the step 1; 3, the yarn obtained in the step 2 is subjected to liquid ammonia treatment, according to the treating process, the temperature of liquid ammonia is -20 to 5 DEG C, the soaking time is 2-5 min, and washing, dehydration and secondary drying are conducted after primary drying. According to the strong twisted yarn with the stable degree of twist and the production technology of the strong twisted yarn, the short fiber two-for-one twister is utilized to secondarily twisting the spun common twisted yarn, the stretching strength of the yarn is improved, the intensity of the yarn is improved, therefore the strong twisted yarn which is superior in performance is obtained, and the requirement of a weaving work procedure for the strong twisted yarn of many varieties can be well met.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a strong twisted yarn with stable twist and a production process thereof. Background technique [0002] At present, the competition in the textile market is becoming increasingly fierce, and textile technology is developing rapidly. Only by focusing on the innovation of fabrics can enterprises obtain real differentiated competitiveness. With the continuous improvement of people's living standards, people's requirements for clothing are getting higher and higher. The fabrics are rich in categories, comfortable and natural, safe and environmentally friendly, especially fashion outerwear fabrics. They show individuality, pursue fashion and reflect their unique styles. . In recent years, "wrinkle" has become popular in domestic and foreign markets. This kind of fabric is mainly made of strong-twisted yarn. Strong-twisted yarn has a larger twist than normal yarn, so the ...
