Embodiment Construction

[0020] 1. Spinning false twisting device and its installation structure:

[0021] like figure 1 , 2 As shown, when the present invention spun yarn, the support 5 of the false twisting device is fixed on the yarn guide plate 9 through the connector 6 .

[0022] A cylindrical barrel 1 is supported on a bracket 5 through a pair of bearings 4 .

[0023] The driven gear 3 is coaxially fixedly connected outside the cylinder body 1, and three pulleys 16, 15, 2 are respectively arranged through the support shaft along the length direction of the cylinder body 1 in the cylinder body 1, and the axial directions of each pulley are parallel to each other and parallel to the cylinder body 1 are perpendicular to each other. The inner diameter of the cylinder 1 is 10-15mm, the length is 60-65mm, the axial distance between adjacent pulleys is 20-25mm, the distance between the pulley 16 and the port of the cylinder 1 is 5-10mm, the distance between the pulley 2 and the cylinder The distanc...

Abstract

The invention relates to the spinning technical field, in particular to a low-twist high-strength yarn and the spinning technology of the low-twist high-strength yarn. Blending is carried out on terylene and cotton which are blended according to the feeding mass ratio of 50-70:30-50, the opening picking procedure, the cotton carding procedure, the combing procedure, the drawing procedure, the roving procedure and the spinning procedure are carried out, and a terylene / cotton blending yarn with the fineness degree of 7.4-36.7tex, the twist coefficient of 260-300 and the strength of 20-35cN / tex is spun. According to the low-twist high-strength yarn and the spinning technology, the variety adaptation of the low-twist high-strength yarn is improved, the yarn strength is improved, under the condition that the design twist coefficient is reduced by 10%-35%, the tensile strength of the blending yarn is 5%-10% higher than that when the twist coefficient is normally designed, and the foundation is laid for the development of the shell fabric with the good softness and comfort performance.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning process of low-twisted high-strength yarn. Background technique [0002] With the improvement of people's living standards, consumers have put forward higher requirements for the softness of fabrics. Reducing the yarn twist in fabrics is an effective way to improve the softness of fabrics. However, the reduction of yarn twist will make the yarn The thread strength decreases, which will eventually affect the weaving and dyeing and finishing processes. [0003] Ring spinning, which achieves twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used and most common spinning method in the market. The technology is very mature. New spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirlin...
