Preparation method of high-count composite yarn

A composite yarn, high-count technology, applied in the direction of yarn, textiles and papermaking, can solve the problems of affecting the degree of fiber cohesion, spun silk fibers are prone to static electricity, easy to generate fuzz and entanglement, etc., to achieve stable and improved yarn quality. The effect of feeling bulky and high internal cohesion

Problems solved by technology

However, in the process of weaving composite yarns, the two fibers have their own defects, which restrict the development of weaving technology: the single fiber strength of cashmere fiber is low, the length of the main body is short, and it is difficult to develop yarns with higher counts. Cashmere high-count yarn fabrics cannot effectively make the fabric develop in a light and thin direction; thinner cashmere fibers are inevitably weaker in strength, and too short fiber lengths will also affect the degree of cohesion between fibers during yarn formation; spun silk fibers It is easy to generate static electricity, and it is easy to produce hair particles and entanglement during the carding process, which seriously increases the difficulty of weaving and also affects the appearance quality of the fabric

Embodiment 1

[0038] A preparation method of high-count composite yarn, the specific steps are as follows:

[0039] 1) choose respectively that count is 80S, average length is 25 parts by weight of 1# cashmere fiber of 45mm, count is 48S, average length is 15 parts by weight of 2# cashmere fiber of 80mm, to 1# and 2# cashmere fiber raw material respectively Add the wool treatment agent in the wool blending machine, and then mix it in the wool blending machine to obtain the wool wool fiber, then seal the above wool wool fiber, and place it in a humidification room with a temperature of 60°C and a relative humidity of 85% for 30 hours to make the fiber fully Absorb antistatic oil agent and moisture, finally obtain pretreatment 1# cashmere fiber and pretreatment 2# cashmere fiber; Above-mentioned and wool treatment agent comprise following raw materials by weight: 0.6 part of antistatic agent, 0.7 part of wool oil, 0.3 part of organic Silicone oil, 0.5 parts of penetrating agent JFC and 10 par...

Embodiment 2

[0049] A kind of preparation method of high-count composite yarn, when working, the difference with embodiment 1 only lies in: in the pretreatment step of cashmere fiber, also comprise the o-nitrobenzoic acid of 0.05 weight part and 0.08 in the wool treatment agent Glycine in parts by weight.

Embodiment 3

[0051] A method for preparing a high-count composite yarn, when working, differs from Example 1 only in that: in step 8), the dimension-removal treatment liquid includes: 2.5g / L penetrating agent DJ-1399, 5g / L of NaOH and 0.08g / L of diphenylphosphoric acid, the solvent is water; no d-quinic acid is added.

Abstract

The invention provides a preparation method of high-count composite yarn, and relates to the technical field of textile. The preparation method includes the steps of wool top dyeing, sliver mixing, gilling, roving, primary twisting, napping, secondary twisting, rewinding and finished product packaging, and the specific steps are as follows: providing 1# cashmere fibers and 2# cashmere fibers, and carrying out the steps of wool top dyeing, sliver mixing, gilling and roving, to form 1# rove and 2# rove; using the two pieces of spun silk as core yarn, using the 1# rove as decorative yarn, and forming napping yarn through the step of primary twisting; after carrying out napping treatment on the napping yarn, by using the napping yarn as core yarn, using the 2# rove as non-overfeeding decorative yarn, and using a PVA filament as fixed yarn, carrying out secondary twisting to prepare wrap yarn; and and rewinding the warp yarn, thus obtaining the high-count composite yarn. According to the preparation method provided by the invention, equipment parts of a twisting machine are modified, and the spun silk and the cashmere are combined into the composite yarn of which the count can reach 100 or above by the way of combining the napping yarn with the wrap yarn.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of high-count composite yarn. Background technique [0002] The textile industry was originally a traditional industry with a long history. After so many years of continuous innovation and improvement, the challenges it faces today are very daunting. The textile industry has experienced a whole year of reshuffle in 2019. Coupled with the spread of the new coronavirus in early 2020, all textile people around the world are tense. The industry is going through the "Great Recession". China is the world's largest producer, consumer and exporter of textiles and clothing. It is the country with the most complete textile industry chain and the most complete categories. It has a solid foundation and obvious advantages to enter the camp of the world's textile powers. With the development of science and technology and the advent of the Internet + era, the...
