Embodiment 1

[0052] Preparation of polymer hybrid pigments:

[0053] 1) Use the washing method to remove the salt and other substances of the industrial-grade pigment crystals, specifically: the pigment crystal dispersion liquid is subjected to centrifugation washing at 10000r / min, 8000r / min, and 5000r / min in sequence, and centrifuged for 8 minutes each time;

[0054] 2) Take the washed pigment crystal dispersion, emulsifier OP-10 and water (the mass ratio of the three is 1:0.28:64) and mix and stir for 30 minutes, add St, BA and 4-[(2R)-3,4- Dihydro-7-hydroxyl-2H-1-benzopyran-2-yl]-3-(3-methyl-2-buten-1-yl)-1,2-benzenediol (three The mass ratio is 1:1.2:1), wherein the ratio of the total mass of the pigment crystal dispersion liquid to the monomer is 1:3.1, and then HD and SDS are added (the mass ratio of St, HD and SDS is 1:0.11:0.06), Mixing and stirring for pre-emulsification for 1 hour, then ultrasonication at 150W for 20 minutes; then adding the initiator KPS, stirring and reacting ...

Embodiment 2

[0071] The difference between the preparation of the polymer hybrid pigment and Example 1 is that the mass ratio of the pigment crystal dispersion, OP-10, and water is 1:0.22:62.5; St, BA and 4-[(2R)-3, The mass of 4-dihydro-7-hydroxy-2H-1-benzopyran-2-yl]-3-(3-methyl-2-buten-1-yl)-1,2-benzenediol The ratio is 1:1.3:0.84; the mass ratio of St, HD and SDS is 1:0.06:0.07; the ratio of pigment crystal dispersion liquid to the total mass of monomer is 1:2.4.

[0072] The preparation of silicone oil is the same as in Example 1.

[0073] A method for preparing fancy cashmere yarns using color-spun fibers is the same as in Example 1.

Embodiment 3

[0075] The difference between the preparation of the polymer hybrid pigment and Example 1 is that the mass ratio of the pigment crystal dispersion, OP-10, and water is 1:0.32:61.5; St, BA and 4-[(2R)-3, The mass of 4-dihydro-7-hydroxy-2H-1-benzopyran-2-yl]-3-(3-methyl-2-buten-1-yl)-1,2-benzenediol The ratio is 1:0.95:1.1; the mass ratio of St, HD and SDS is 1:0.14:0.05; the ratio of pigment crystal dispersion liquid to the total mass of monomer is 1:1.6.

[0076] The preparation of silicone oil is the same as in Example 1.

[0077] A method for preparing fancy cashmere yarns using color-spun fibers is the same as in Example 1.

Abstract

The invention discloses a method for preparing fancy cashmere yarns by using colored spun fibers, and relates to the technical field of spinning. The method specifically comprises the following steps: S1, dyeing cashmere wool to prepare uniform wool tops, putting the wool tops into production, and making the wool tops into rough yarns through worsted spinning or semi-worsted spinning; S2, conducting fancy twisting PAFA production, namely carrying out fancy yarn production on the rough cashmere yarns by adopting a fancy twisting machine to obtain fancy cashmere yarns; S3, conducting napping on the made fancy cashmere yarns; S4, performing yarn steaming on the napped yarns; and S5, rewinding the steamed yarns into cone yarns to obtain a product. According to the method provided by the invention, a technological process is greatly shortened, cost is reduced, yarn delivery efficiency is improved, the problem of chromatic aberration is avoided, and the method has the advantages of energy conservation and emission reduction; and the prepared fancy cashmere yarns are excellent in mechanical property and good in softness, the color fastness of pigment on a fabric is high, and dye uptake is better.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a method for preparing fancy cashmere yarn from colored spinning fibers. Background technique [0002] Color spinning is to dye the fiber into colored fiber, which can realize the hazy three-dimensional effect and texture that cannot be achieved by white blank dyeing. Color spinning is pollution-free and can control color difference to the greatest extent. Therefore, the color is soft and fashionable, and the colored spun yarn, which can cope with the flexible production of small batches and multiple varieties, is more and more used in medium and high-end clothing products. Due to the new process of "dyeing first, then spinning", color spinning shortens the production process of downstream processing enterprises, reduces production costs, and has high added value. Compared with the traditional method of "spinning first and then dyeing", The performance of color spi...
