Embodiment 1

[0050] Before sizing, the moisture regain of the yarn on the warp beam is controlled to 35%, and the yarn is sequentially subjected to sizing treatment, drying treatment, dry splitting treatment, waxing treatment and coiling treatment, and the unwinding tension of the warp beam is 550N , the traction tension of the sizing tank is 350N, the sizing tension is 2140N during the waxing process, the sizing tension is 2200N during the dry splitting process, and the coiling tension during the coiling process is 2250N. No delamination or wet splitting treatment is performed. In the drying process, slow train operation is adopted in the drying area, and the drafting tension is increased. The speed of the machine is controlled at 45m / min. During the drying process, the yarn tension is 600N, and the yarn The moisture regain is controlled at 9%, the viscosity of the size tank is controlled at 7s, the solid content is controlled at 11%, and the sizing rate is controlled at 10%.

Embodiment 2

[0052] Before sizing, the moisture regain of the yarn on the warp beam is controlled to 25%, and the yarn is sequentially subjected to sizing treatment, drying treatment, dry splitting treatment, waxing treatment and coiling treatment, and the unwinding tension of the warp beam is 500N , the traction tension of the sizing tank is 300N, the sizing tension is 1920N during the waxing process, the sizing tension is 2000N during the dry splitting process, and the coiling tension during the coiling process is 2000N. No delamination, no wet split twisting treatment, in the drying process, use slow train operation in the drying area, increase the draft tension, control the speed of the machine to 35m / min, during the drying process, the yarn tension is 500N, the yarn The moisture regain is controlled at 8%, the viscosity of the size tank is controlled at 7s, the solid content is controlled at 11%, and the sizing rate is controlled at 10%.

Embodiment 3

[0054] Before sizing, the moisture regain of the yarn on the warp beam is controlled to 30%, and the yarn is sequentially subjected to sizing treatment, drying treatment, dry splitting treatment, waxing treatment and coiling treatment, and the unwinding tension of the warp beam is 550N , the traction tension of the sizing tank is 325N, the sizing tension is 2030N during the waxing process, the sizing tension is 2100N during the dry splitting process, and the coiling tension during the coiling process is 2125N. No delamination or wet splitting treatment is carried out. During the drying process, the slow train operation is adopted in the drying area, the drafting tension is increased, and the speed is controlled at 40m / min. During the drying process, the yarn tension is 550N, and the yarn The moisture regain is controlled at 7%, the viscosity of the size tank is controlled at 7s, the solid content is controlled at 11%, and the sizing rate is controlled at 10%.

Abstract

The invention relates to a pure cotton high count and high density compact spinning sized yarn production method. The method comprises the following steps that 1, the prepulp moisture regain of yarn is controlled to be 25-35%; 2, the yarn is subjected to sizing treatment, drying treatment and dry lease treatment in sequence, the vehicle speed of a sizing machine is 35-60 m / min, when the yarn is subjected to drying treatment, the moisture regain of the yarn is controlled to be 7-9%, the drying temperature is controlled to be 60-90 DEG C, and the yarn tension is controlled to be 350-650 N; 3, the yarn is subjected to waxing treatment and take-up treatment in sequence. According to the compact spinning sizing technology, the problem that brittle fracture is likely to occur, and then the weaving efficiency is low is effectively solved, and the warp beam quality and weaving efficiency are significantly improved.

Description

technical field [0001] The invention relates to the technical field of textile processing technology, in particular to a production method of pure cotton high-count and high-density compact sizing yarn. Background technique [0002] Pure cotton high-count and high-density compact spinning has the characteristics of compact spinning structure, smooth yarn, less hairiness, and high strength. Due to the high strength of compact spinning, less hairiness, and obvious advantages in weaving, it is very popular and more and more The ground is used as a warp. However, due to these characteristics of compact spinning, new problems have arisen in compact spinning when sizing: tight-structured compact spinning can easily cause reed teeth to hit the reed teeth in the pre-separation area after sizing, and it is easy to cause brittleness when the skein rod is spun. Breakage, resulting in increased yarn breakage in the front yarn dividing area, which seriously affects the quality of the pu...
