Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, and particularly relates to a shrink-proof brocade-cotton fabric. Background Art

[0002] Clothes made of cotton fiber fabrics are prone to shrinkage after washing, which affects normal use. Therefore, it is necessary to carry out anti-shrinkage treatment on cotton fiber fabrics. A common anti-shrinkage treatment method is to add chemical fibers with excellent anti-shrinkage performance, such as polyamide fiber, to the cotton fiber fabrics. Although the cotton fiber fabrics added with polyamide fiber overcome the shortcoming of shrinkage to a certain extent, they have an impact on the skin-friendly comfort of the fabrics, and at the same time, they will also cause a decrease in the moisture absorption and sweat discharge ability of the cotton fiber fabrics, which urgently needs to be improved. For this reason, the utility model provides a shrink-proof brocade-cotton fabric. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shrink-proof brocade-cotton fabric.

[0016] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] As Figure 1 shown, an anti-shrinkage brocade cotton fabric includes: a surface layer 1 and a lining layer 2.

[0018] The surface layer 1 is disposed on one side of the lining layer 2 and is formed by interweaving warp yarns and weft yarns. Both the warp yarns and the weft yarns are made of elastic brocade cotton composite yarn.

[0019] As Figure 2 shown, the elastic brocade cotton composite yarn includes a core filament and a wrapping filament helically wound around the outside of the core filament. The core filament is a cotton-covered spandex yarn, and the wrapping filament is a moisture-absorbing polyamide fiber yarn 11. The core yarn of the cotton-covered spandex yarn is a spandex filament 12, and the covering yarn is a cotton fiber yarn 13. The cotton-covered spandex yarn has good elasticity and moisture absorption and breathability. The moisture-absorbing polyamide fiber yarn 11 has abrasion resistance and hygroscopicity, making the surface layer 1 more wear-resistant and durable. The elastic brocade cotton composite yarn has excellent hygroscopicity, making the surface layer 1 hydrophilic.

[0020] Preferably, the cotton fiber yarn 13 is an antibacterial cotton fiber yarn, which is obtained by impregnating a conventional cotton fiber yarn with an antibacterial finishing solution, so that the surface layer 1 has antibacterial properties.

[0021] The spandex filament 12 used in the surface layer 1 is a moisture-absorbing spandex filament to improve the moisture absorption capacity of the surface layer 1. The mass percentage composition of the moisture-absorbing spandex filament is: poly(ethylene oxide) and / or propylene oxide-based fiber-forming polymer 10.0 - 30.0%; polytetramethylene ether glycol-based fiber-forming polymer 62.5 - 88.5%; polyacrylate 1.0 - 5.0%; ultraviolet absorber 0.1 - 0.5%; antioxidant 0.1 - 0.5%; lubricant 0.2 - 1.0%; delustering agent 0.1 - 0.5%.

[0022] The moisture-absorbing polyamide fiber yarn 11 is spun from moisture-absorbing and breathable linen-like polyamide fibers. The preparation method of the moisture-absorbing and breathable linen-like polyamide fibers comprises the following steps: (1) Feeding: Fiber-grade polyamide 6 chips with a relative viscosity of 2.6 - 2.8 and a moisture content ≤ 50 ppm are put into a bin in a nitrogen atmosphere, and at the same time, a cross-linking agent and a modified masterbatch are put into the bin in a nitrogen atmosphere; (2) Melting and spinning: The fiber-grade polyamide 6 chips, the cross-linking agent, and the modified masterbatch protected by nitrogen in the bin are together fed into a screw extruder to be extruded and melted into a melt, and after being uniformly mixed by a screw mixing head, they are transported to a melt pipe. The melt enters a spinning assembly through a spinning metering pump for metering and pressurization, and is filtered and mixed, and then the melt stream is extruded through the spinneret micropores. The melting temperature is controlled at 250 - 255 °C; (3) Oiling and winding forming: The melt stream is cooled and solidified into fibers by side blowing during high-speed movement, and after being oiled and bundled, it is wound and formed; (4) False twist texturing: The fibers obtained in step (3) are placed on the raw silk frame of a polyamide fiber false twist texturing machine, and then pass through a first roller, a hot box, a cooling plate, a false twister, and a second roller respectively and then are wound and formed; wherein, the parameters of false twist texturing are controlled as follows: draw ratio 0.85 - 1.15, hot box temperature 180 - 220 °C, D / Y 1.75 - 2.5, processing speed 300 - 450 m / min; (5) Heat treatment: The fibers obtained in step (4) are dry heat-treated in an oven at 80 - 100 °C for 10 - 30 min or wet heat-treated in boiling water for 10 - 30 min, and are placed at room temperature for more than 30 min after heat treatment.

[0023] The inner layer 2 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are cotton-like polylactic acid composite yarns.

[0024] As Figure 3As shown, the cotton-like polylactic acid composite yarn is formed by twisting and doubling a cotton-like elastic yarn and a polylactic acid elastic yarn. The cotton-like elastic yarn includes spandex filaments 12 and a cotton-like polyester fiber yarn 14 spirally wound around the outside of the spandex filaments 12. The polylactic acid elastic yarn includes spandex filaments 12 and polylactic acid filaments 15 spirally wound around the outside of the spandex filaments 12. The cotton-like elastic yarn has good elasticity and a soft hand feeling, making the inner layer 2 more comfortable to touch the skin. The polylactic acid elastic yarn has good elasticity, a soft hand feeling and antibacterial function, which can improve the skin-friendly property of the inner layer 2 and endow the fabric with certain antibacterial ability. The hygroscopicity of both the cotton-like elastic yarn and the polylactic acid elastic yarn is poor, making the inner layer 2 hydrophobic.

[0025] Through the cooperation of the hydrophilicity of the outer layer 1 and the hydrophobicity of the inner layer 2, the rapid discharge of sweat can be realized, ensuring the comfort of wearing.

[0026] Preferably, the polylactic acid filaments 15 are cool-sensation polylactic acid filaments, making the fabric have a cool feeling when touching the skin and being more suitable for summer clothing.

[0027] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
