Abstract
Description
Technical Field
[0001] This utility model relates to a triacetic acid breathable and antibacterial knitted elastic fabric, belonging to the technical field of knitted elastic fabrics. Background Technology
[0002] Fiber acetate, also known as cellulose acetate fiber, is one of the earliest developed chemical fibers in the world. Currently, it is the second largest variety of regenerated cellulose fiber after viscose fiber. Triacetate fabric is a man-made fiber fabric, with cellulose acetate as its main component. Triacetate fiber is produced from cellulose pulp as raw material, which is acetylated to form cellulose esterification derivatives, and then produced through a dry spinning process. Based on the degree to which the hydroxyl groups (OH) in cellulose are replaced by acetyl groups (COCH3), it is divided into triacetate fiber (CTA) and diacetate fiber (CDA). Triacetate fiber fabric has an appearance and luster similar to silk, a soft, smooth, and elastic feel, and drapes similarly to silk. It possesses the texture of silk but is stiffer. It is easy to wash and dry, resistant to mildew and moths, anti-static, comfortable against the skin, and has a cooling sensation when worn, making it a raw material for high-end fabrics. However, existing triacetate fabrics have good moisture absorption, tending to stick to the skin after absorbing moisture, especially elastic fabrics, which are even more skin-friendly. Furthermore, they are prone to bacterial growth after absorbing moisture. The problem to be solved is how to prepare a triacetic acid breathable and antibacterial knitted elastic fabric with moisture-wicking properties. Utility Model Content
[0003] The purpose of this invention is to provide a triacetic acid breathable and antibacterial knitted elastic fabric that has good elasticity and breathability, and also has a moisture-wicking effect.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:
[0005] The present invention relates to a triacetic acid breathable antibacterial knitted elastic fabric, comprising a knitted elastic fabric base layer woven on a double-sided circular knitting machine, wherein the knitted elastic fabric base layer comprises a first fabric layer and a second fabric layer connected by tuck yarns.
[0006] The first fabric layer is woven from a first elastic core-spun yarn in a plain weave pattern, and the second fabric layer is woven from a second elastic core-spun yarn in a pique pattern.
[0007] The first elastic core-spun yarn includes an elastic filament and a triacetate filament covering the outside of the elastic filament; the second elastic core-spun yarn includes an elastic filament and an antibacterial chemical fiber filament covering the outside of the elastic filament.
[0008] The tucked yarn includes elastic filaments and moisture-wicking chemical fiber filaments covering the outer side of the elastic filaments.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the moisture-wicking chemical fiber filament is a polyester filament, nylon 6 filament or PLA filament with a cross-shaped or Y-shaped cross section.
[0011] Based on the above solution and as a preferred embodiment of the above solution: the knitted elastic fabric base layer includes:

[0024] The yarn used in the third, fifth, eighth, and tenth yarns is the first elastic core-spun yarn.
[0025] Based on the above scheme and as a preferred embodiment of the above scheme: the second elastic core-spun yarn is further wrapped around the triacetate filament of the elastic filament, and the triacetate filament and the antibacterial chemical fiber filament are spirally wound around the outside of the elastic filament in opposite directions.
[0026] Based on the above scheme and as a preferred embodiment of the above scheme: the surface of the first fabric layer away from the second fabric layer has a nano zinc oxide film layer formed by vacuum deposition technology; a nano titanium dioxide film layer is disposed on the outside of the nano zinc oxide film layer.

Knitted fabrics are composed of nested loops, providing better breathability than woven fabrics. The pique knit structure creates a mesh in the second fabric layer 200, further enhancing the fabric's breathability.
[0036] The first elastic core-spun yarn includes an elastic filament and a triacetate filament covering the outside of the elastic filament. Specifically, the elastic filament is a spandex filament with a fineness of 40D; the triacetate filament has a fineness of 50D.
[0037] The second elastic core-spun yarn includes an elastic filament and an antibacterial synthetic fiber filament covering the outer edge of the elastic filament; the antibacterial synthetic fiber filament is an antibacterial nylon 6 filament. The elastic filament used is spandex filament with a fineness of 40D; the antibacterial nylon 6 filament has a fineness of 75D. Specifically, the antibacterial nylon filament is nano-zinc oxide modified nylon 6 filament, which is produced by adding nano-zinc oxide particles with a particle size less than 100nm during the melt spinning of the nylon 6 filament, at a dosage of 5%.
[0038] The tucked yarn comprises an elastic filament and a moisture-wicking synthetic filament covering the outer side of the elastic filament. The elastic filament used is spandex filament with a fineness of 20D. The moisture-wicking synthetic filament is polyester filament, nylon 6 filament, or PLA filament with a cross-shaped or Y-shaped cross-section. In this embodiment, a cross-shaped polyester filament with a fineness of 45D / 24F is selected.
[0039] Furthermore, the knitted elastic fabric base layer is woven from a ten-way yarn system, specifically including:
[0040] First row 1: The needle plate has a floating thread and a tufted loop in sequence, and the syringe has a tufted loop and a floating thread in sequence.
[0041] Second route 2: Form loops on the syringe, but do not knit on the needle plate.
[0042] The third row (3): loops are formed on the needle plate, but not on the needle cylinder.
[0043] Fourth row 4: The needle cylinder is used for tucking and forming loops in sequence, and no knitting is done on the needle plate.
[0044] Fifth row 5: It forms circles on the needle plate, but is not knitted on the needle cylinder.
[0045] 6th row: On the needle plate, there are tufted loops and floats in sequence; on the syringe, there are floats and tufted loops in sequence.

[0049] 10th row 10: It forms a circle on the needle plate, but is not knitted on the needle cylinder.
[0050] The yarn used in the first and sixth channels (1 and 6) is a tucked yarn. The yarn used in the second, fourth, seventh, and ninth channels (2, 4, 7, and 9) is a second elastic core-spun yarn. The yarn used in the third, fifth, eighth, and tenth channels (10) is a first elastic core-spun yarn.
[0051] Example 2
[0052] Combination Figure 3 This embodiment will be described in detail below. The triacetate breathable antibacterial knitted elastic fabric involved in this embodiment differs from Embodiment 1 in that: the second elastic core-spun yarn is further wrapped around the triacetate filament of the elastic filament, and the triacetate filament and the antibacterial chemical fiber filament are spirally wound in opposite directions on the outside of the elastic filament. The surface of the first fabric layer 100 away from the second fabric layer 200 has a nano-zinc oxide film layer 300 formed using vacuum deposition technology; a nano-titanium dioxide film layer 400 is disposed on the outside of the nano-zinc oxide film layer 300. The nano-zinc oxide film layer 300 and the nano-titanium dioxide film layer 400 are provided to improve the waterproof effect of the fabric. The use of the nano-zinc oxide film layer 300 can improve the antibacterial effect of the fabric, while the use of the nano-titanium dioxide film layer 400 can improve the UV resistance of the fabric and protect the nano-zinc oxide film layer 300. Since the nanoparticles are attached to the fiber surface, they do not affect the breathability of the fabric. The fabric was tested for antibacterial properties and showed an inhibition rate of 99% against Staphylococcus aureus (AATCC 6538) and 92% against Escherichia coli (8099).
