Description

Technical Field

[0001] This utility model relates to a triacetic acid memory fabric, belonging to the technical field of triacetic acid fabrics. Background Technology

[0002] Acetate fiber, one of the earliest developed chemical fibers in the world, is currently 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 by using cellulose pulp as raw material, acetylating it to form cellulose esterification derivatives, and then dry spinning it. Based on the degree of substitution of hydroxyl groups (OH) in cellulose with 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 has the texture of silk but is stiffer, easy to wash and dry, mildew-proof, moth-proof, anti-static, comfortable against the skin, and has a cooling sensation when worn. It is a raw material for high-end fabrics. Memory fabric, also called memory cloth, refers to fabric with shape memory function. This fabric is wrinkle-free and easy to care for, making it the first choice for making suits, trench coats, jackets, women's suits, etc. There are no reports on triacetate memory fabrics on the market yet. How to prepare a triacetate memory fabric that has good wrinkle recovery and wearing comfort has become a problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a triacetate memory fabric that has the luster and wrinkle recovery properties of silk fabric.

[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 triacetate memory fabric, comprising a composite triacetate elastic fabric and a wool blend elastic fabric.

[0006] The triacetate elastic fabric is woven from a first warp and a first weft in a satin weave. The first warp is a triacetate memory core-spun yarn, and the first weft is a cashmere / linen / shape memory polyester blended yarn. The triacetate memory core-spun yarn includes shape memory filaments and triacetate filaments covering the outside of the shape memory filaments.

[0007] The cashmere blended elastic fabric is woven from a second warp and a second weft in a plain weave. The second warp is a shape memory filament and descaled wool covering the outside of the shape memory filament. The second weft is a wool / Sorona worsted yarn.

[0015] Figure 1 This is a structural schematic diagram of the triacetate memory fabric involved in Example 1;

[0016] Figure 2 This is a schematic diagram of the triacetic acid memory fabric involved in Example 2. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1This embodiment will be described in detail below. The triacetate memory fabric involved in this embodiment includes a composite triacetate elastic fabric 1 and a wool blend elastic fabric 2. Specifically, it is composited using a dotted hot melt adhesive. The spacing between each dot of the dotted hot melt adhesive is 3-8 mm, and the bonding area accounts for 25-40%. Specifically, in this embodiment, the dotted hot melt adhesive is circular, with a spacing of 5 mm between each dot, and the bonding area dot ratio is 30%.

[0020] The triacetate elastic fabric 1 is woven from a first warp and a first weft in a satin weave. The first warp is a triacetate memory core-spun yarn, which includes shape memory filaments and triacetate filaments covering the shape memory filaments. The triacetate filaments have a fineness of 50D, and the shape memory filaments have a fineness of 40D. One side of the satin weave fabric exhibits warp-faced characteristics with warp floats, while the other side exhibits weft-faced characteristics with weft floats.

[0021] The first weft yarn is a blend of cashmere, linen, and shape memory polyester fiber, with a fineness of 14.6 tex. Shape memory polyester fiber (MEM-PET) is a fiber that can quickly deform or return to its initial shape and properties under specific external conditions. Linen fiber has natural functions such as temperature regulation, skin protection, and antibacterial properties. Linen fabric has excellent properties such as a natural appearance, crisp feel, easy washing, and dust resistance, and is recognized as one of the most comfortable and hygienic fabrics. Cashmere fiber is a high-end fiber, known for its strong moisture absorption, lightness, warmth, soft and smooth feel, natural luster, and comfortable wear. The blending of multiple fibers can achieve complementary advantages.

[0022] The cashmere blended elastic fabric 2 is woven from a second warp and a second weft in a plain weave. The second warp consists of shape memory filaments and descaled wool covering the shape memory filaments. The second weft is a wool / Sorona worsted yarn, specifically a 50 / 50 blend with a fineness of 60 count. Sorona fiber has a unique "spring-like" molecular structure, exhibiting excellent elasticity and shape memory properties, and can recover its original shape even at a 20% elongation.

[0023] Furthermore, the shape memory filament is a shape memory PTT filament or a shape memory spandex filament. In this embodiment, a shape memory PTT filament is selected.

[0024] Furthermore, the triacetate elastic fabric 1 is characterized by one side of the weft float yarn being close to the wool blend elastic fabric 2, while the warp float yarn is characterized by one side of the warp surface being on the outside, exhibiting the luster effect of triacetate filaments.

[0025] Tests showed that the average crease recovery angle of the fabric prepared in this embodiment was 334.5°. After being subjected to external pressure and folding, the surface fabric can well recover its original shape, is not prone to persistent wrinkles, and exhibits good shape memory properties.

[0026] Example 2

[0027] Combination Figure 2 This embodiment will be described in detail below. The triacetate memory fabric involved in this embodiment differs from that in Embodiment 1 in that a phase change memory fabric 3 is provided between the triacetate elastic fabric 1 and the wool blend elastic fabric 2; the phase change viscose elastic yarn includes shape memory filaments and a phase change viscose fiber layer covering the outside of the shape memory filaments. The shape memory filaments used are 40D shape memory spandex filaments.

[0028] Furthermore, the outer side of the phase change viscose fiber layer is also spirally wound with nano-zinc oxide modified nylon 6 filaments. The nano-zinc oxide modified nylon 6 filaments have a fineness of 50D and possess antibacterial properties.

[0029] Another difference from Example 1 is that the triacetate elastic fabric 1 has a nano-zinc oxide film layer 4 formed using vacuum deposition technology on the side away from the wool blend elastic fabric 2; a nano-titanium dioxide film layer 5 is provided on the outer side of the nano-zinc oxide film layer 4. The nano-zinc oxide film layer 30 and the nano-titanium dioxide film layer 40 are provided to improve the waterproof effect of the fabric. The use of the nano-zinc oxide film layer 30 can improve the antibacterial effect of the fabric, while the use of the nano-titanium dioxide film layer 40 can improve the UV protection effect of the fabric and can protect the nano-zinc oxide film layer 30. Since the nanoparticles are attached to the fiber surface, they do not affect the breathability of the fabric. The UV-protective fabric was tested according to GB / T18830-2009 "Evaluation Standard for UV Protection Performance of Textiles", and the UPF value was 57. The fabric was tested for antibacterial properties, and the inhibition rate against Staphylococcus aureus (AATCC 6538) reached 99%, and the inhibition rate against Escherichia coli (8099) reached 93%.

[0030] 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.
