Description

Technical Field

[0001] This utility model relates to a yarn, specifically an easy-to-dye, skin-friendly wool yarn. Background Technology

[0002] Traditional wool yarn suffers from a scaly structure on the surface of wool fibers. During conventional dyeing, this scaly structure hinders dye adsorption and diffusion. A boiling dyeing process using strong acidic dyes is typically employed, but the wool fibers are damaged to varying degrees in the boiling acidic dye bath, resulting in decreased strength, yellowing color, and reduced quality. Furthermore, traditional wool yarn is not skin-friendly; some yarns have rough fiber surfaces that can cause itching upon direct contact with the skin. Therefore, it is necessary to provide an easily dyeable, skin-friendly wool yarn. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combination Figure 1 This embodiment provides a detailed description of an easily dyeable, skin-friendly wool yarn, comprising: a yarn body, the yarn body including a first yarn 1 and a second yarn 2; the first yarn 1 and the second yarn 2 are twisted together; the first yarn 1 includes a first core yarn 3 and a first wrapping yarn 4, the first wrapping yarn 4 being spirally wound around the outside of the first core yarn 3, the first core yarn 3 being an antibacterial yarn, and the first wrapping yarn 4 including cationic dyeable wool fiber yarn; the second yarn 2 includes a second core yarn 5 and a second wrapping yarn 6, the second wrapping yarn 6 being spirally wound around the outside of the second core yarn 5, the second core yarn 5 being a thermal insulation yarn, and the second wrapping yarn 6 being an acrylic fiber yarn.

[0016] Cationic dyeable wool fiber is wool fiber obtained by modifying it with anionic modifiers that can react with amino groups, hydroxyl groups and other groups in wool fiber. Cationic dyeable wool fiber has a large number of anions. When dyed with Li Yanzi dye, it can form ionic bonds with the cations in the cationic dye through anion-cation bonding, thereby improving the dyeing rate of cationic dye. Cationic dyeable wool fiber dyed with cationic dye has high color fastness, with rubbing fastness and washing fastness both at grade 3-4 or above, which is 1-2 grades higher than ordinary wool.

[0017] Furthermore, the antibacterial yarn is a copper-modified polyamide 6 antibacterial fiber filament. The copper-modified polyamide 6 antibacterial fiber is prepared by surface modification of spherical copper powder with oleic acid, followed by blending and granulation of the modified copper powder with polycaprolactam chips to obtain Cu-PA6 antibacterial chips with a copper powder mass fraction of 1.1%, which are then produced through melt spinning. The copper-modified polyamide 6 antibacterial fiber exhibits good mechanical properties, excellent and long-lasting antibacterial performance, and an inhibition rate of over 99% against Candida albicans, Escherichia coli, and Staphylococcus aureus before and after washing.

[0018] Furthermore, the insulating yarn is a hollow polyester fiber filament. Specifically, in this embodiment, the hollowness of the hollow polyester fiber filament is 40%, and the amount of still air contained in the hollow polyester fiber filament is higher than that of ordinary polyester filament, thus exhibiting better insulating properties.

[0019] Furthermore, the acrylic fiber in the acrylic fiber yarn is Dralon fine denier profiled acrylic fiber. Acrylic fiber has a fluffy and full hand feel and excellent warmth retention. Cationic dyes can ionize into positively charged pigment cations in the dye bath. Acrylic molecules contain acidic groups, such as sulfonic acid groups and carboxylic acid groups, which ionize in water, causing the fiber surface to become negatively charged. Due to the attraction between charges, the pigment cations of the cationic dye are quickly adsorbed onto the acrylic surface, neutralizing the negative charge on the fiber surface and achieving cationic dyeing of the acrylic fiber. Compared with similar acrylic fibers, Dralon fine denier profiled acrylic fiber has a dumbbell-shaped fiber cross-section, good hygroscopicity, high strength, good modulus, and high surface friction coefficient. It can exhibit a soft yet crisp hand feel, good coverage, and a fluffy and full texture, while also possessing the advantages of excellent cationic dyeing performance.

[0020] Cationic dyes can exhibit extremely bright and vivid colors with high color saturation. They possess a strong affinity for fibers such as acrylic and cationic dyeable wool, ionizing in aqueous solutions to release positively charged colored ions that can efficiently bind with acidic groups in the fiber through ionic bonds, thus achieving efficient dyeing. This allows the fiber to fully absorb the dye, increasing the dyeing rate. Under suitable dyeing conditions, the adsorption and penetration of cationic dyes into the fiber are relatively uniform, resulting in fabrics with consistent and uniform color, without significant color differences or spots, greatly improving product quality and appearance. Compared to some other types of dyes, the dyeing process of cationic dyes is typically carried out under milder conditions, such as lower temperatures and shorter times, which helps reduce energy consumption and improve production efficiency. Therefore, the yarn in this embodiment exhibits excellent dyeing performance.

[0021] Example 2

[0022] Combination Figure 2This embodiment will be described in detail. Based on Embodiment 1, the first wrapping yarn 4 further includes acrylic-based milk protein fiber yarn. The cationic dyeable wool fiber yarn and the acrylic-based milk protein fiber yarn are twisted together. Acrylic-based milk protein fiber is prepared by extracting protein molecules from milk, reacting and grafting them with the macromolecular compound polyacrylonitrile, and finally by wet spinning. The breaking strength of acrylic-based milk protein fiber is higher than that of natural cotton, linen, silk, and wool. Its moisture absorption and breaking elongation are also higher than those of cotton. In addition to the many grooves and pores in the longitudinal direction and cross-section, the fiber surface contains a large number of hydrophilic groups. During use, human sweat is quickly absorbed into the grooves of the fiber and then released into the air to evaporate, keeping the skin dry for a long time. At the same time, the special porous structure gives the fiber the property of being warm in winter and cool in summer. Acrylic-based milk protein fiber has a high dyeing rate and fast dyeing speed, uniform dyeing, good color fastness, quick drying after washing and is not easily deformed. Because the fiber has natural antibacterial properties, it is more effective than wool and silk in preventing mold and moths during storage.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
