Problems solved by technology

Because the wool component in the blended yarn is not resistant to strong alkali and cotton enzyme preparations, the scouring and bleaching processes commonly used in cotton cannot be used, so that impurities such as cotton wax, grease, pectin and natural pigments cannot be effectively removed, affecting Improve the hand style, as well as the stability of hair effect and dyeing process
Cashmere fiber is a precious textile fiber among animal fibers. It has good fineness, softness, and smooth handle. It is known as the "king of wool". It is carried out in a specific wool spinning factory, and cashmere needs to be processed on cotton spinning equipment, especially when it is blended with chemical fibers, there are defects such as uneven cashmere in the yarn, easy generation of static electricity in the production process, poor cohesion, and even affect the wearing performance of clothing.

Embodiment 1

[0017] A method for spinning blended yarns. The blended yarns are composed of cashmere, synthetic fibers and viscose fibers. The spinning is completed through the steps of manual mixing, cleaning, carding, drawing and roving. The specific spinning steps are as follows:

[0018] The first step is the selection of raw materials: the mass ratio of cashmere to blended yarn is 4%, the mass ratio of synthetic fiber to blended yarn is 25%, and the mass ratio of viscose fiber to blended yarn is 61%;

[0019] The second step is manual mixing: the cashmere and viscose fiber, viscose fiber and synthetic fiber are mixed by hand;

[0020] The third step, carding: In the carding process, use the FA201 carding machine, set the speed of the cylinder in the carding machine at 240r / min, the speed of the licker-in roller at 760r / min, and the speed of the cover plate at 72.3 mm / min; the doffer speed is controlled at 20r / min, and the five-point spacing between the cylinder and the cover plate is 0...

Embodiment 2

[0025] A method for spinning blended yarns. The blended yarns are composed of cashmere, synthetic fibers and viscose fibers. The spinning is completed through the steps of manual mixing, cleaning, carding, drawing and roving. The specific spinning steps are as follows:

[0026] The first step is the selection of raw materials: the mass ratio of cashmere to blended yarn is 10%, the mass ratio of synthetic fiber to blended yarn is 30%, and the mass ratio of viscose fiber to blended yarn is 60%;

[0027] The second step is manual mixing: the cashmere and viscose fiber, viscose fiber and synthetic fiber are mixed by hand;

[0028] The third step, carding: in the carding process, use the FA201 carding machine, set the speed of the cylinder in the carding machine at 330r / min, the speed of the licker-in roller at 820r / min, and the speed of the cover plate at 100mm / min; the doffer speed is controlled at 28r / min, and the five-point distance between the cylinder and the cover plate is ...

Embodiment 3

[0033] A method for spinning blended yarns. The blended yarns are composed of cashmere, synthetic fibers and viscose fibers. The spinning is completed through the steps of manual mixing, cleaning, carding, drawing and roving. The specific spinning steps are as follows:

[0034] The first step, the selection of raw material: the mass ratio of cashmere accounting for blended yarn is 7%, the mass ratio of synthetic fiber accounting for blended yarn is 26%, and the mass ratio of viscose fiber accounting for blended yarn is 67%;

[0035] The second step is manual mixing: the cashmere and viscose fiber, viscose fiber and synthetic fiber are mixed by hand;

[0036] The third step, carding: in the carding process, use the FA201 carding machine, set the speed of the cylinder in the carding machine at 290r / min, the speed of the licker-in roller at 780r / min, and the speed of the cover plate at 91mm / min; the doffer speed is controlled at 26r / min, and the five-point distance between the c...

Abstract

The invention discloses a blended yarn spinning method. Blended yarn is composed of cashmere, synthetic fiber and viscose acetal fiber, and spinning is finished through manual blending, blowing, cotton carding, drawing and roving. The method has the advantages that manual blending is adopted for mixing of fiber, and the nonuniformity of cashmere in finished yarn is solved; the process that carding is conducted more times than striking in the blowing and cotton carding processes, anti-static coating powder is added, damage to cashmere fiber and fleece falling are reduced, and the phenomenon that cashmere winds the cylinder and doffer easily is solved; the twist of roving is increased, and the defects that adhering, breakage and loosening, caused by the features that the crispation number of cashmere is reduced, and the fiber is smooth, in the processing process are overcome.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning method of blended yarns. Background technique [0002] In order to provide more and more comfortable textile materials for the field of knitted garments and reduce production costs, in recent years, the market has introduced a series of wool cotton (or viscose) yarns, the common ones are 45 / 55, 30 / 70 and 20 / 80 and other gauge blended yarns. Because the wool component in the blended yarn is not resistant to strong alkali and cotton enzyme preparations, the scouring and bleaching processes commonly used in cotton cannot be used, so that impurities such as cotton wax, grease, pectin and natural pigments cannot be effectively removed, affecting It improves the handle style, as well as the hair effect and the stability of the bleaching and dyeing process. Cashmere fiber is a precious textile fiber among animal fibers. It has good fineness, softness, and smooth handle. I...
