Description

Technical Field

[0001] The present invention relates to the technical field of fabric preparation by enzymatic hydrolysis, and specifically relates to a bamboo fiber and wool blended fabric and its processing technology, with the IPC classification number of D06M16. Background Art

[0002] A blended fabric refers to a fabric made from two or more different types of fibers as raw materials, spun into yarns through blending, including textile products made from chemical fibers such as polyester-viscose, polyester-acrylic, polyester-cotton, etc. and natural fibers such as cotton, wool, silk, linen, etc. For example: polyester-cotton fabric, polyester-wool gabardine, etc. Blended fabrics combine two or more different types of fibers organically, complement each other's advantages, coexist with their advantages, and meet people's different requirements for clothing.

[0003] Polyester fiber is a synthetic fiber made from polyester, commonly used in textiles. Polyester fiber has excellent strength, wear resistance and durability; polyester fiber has excellent moisture absorption and is also easy to dry; polyester fiber has a uniform fiber structure and good dyeing properties, and can be made into fabrics of various colors. In the textile industry, polyester fiber is made into polyester fiber through a melt spinning process to prepare fabrics.

[0004] Bamboo fiber is a fiber made from bamboo and wood; bamboo fiber is highly hollow, and fiber gaps are distributed on the fiber surface like capillaries, which can absorb a large amount of water instantly and evaporate it, with fast moisture absorption and drying and a self-cooling effect; in addition to good moisture absorption and breathability that can keep the fabric dry, the "bamboo kun" component contained in bamboo fiber also endows it with natural antibacterial and bacteriostatic properties; the surface of bamboo fiber has no curl, is smooth, and the woven fabric is delicate, smooth, light and comfortable, giving people a feeling of being cared for when contacting the skin.

[0005] Wool fiber is a deformation of the sheep's skin, prone to being moth-eaten; it has strong moisture absorption, can absorb 30% of its own weight of water without feeling wet, and can automatically adjust the temperature, warm in winter and cool in summer; the surface of wool fiber has a scale layer, which can reduce the growth of bacteria; wool fiber also has excellent elasticity, resilience and other properties.

[0006] Although polyester fiber, wool fiber and bamboo fiber have their own characteristics, advantages and disadvantages, there is less existing technology for blending polyester fiber, wool fiber and bamboo fiber to obtain fabrics.

[0064] II. Fabric Testing Test the anti-ultraviolet, air permeability, and antibacterial properties of the above-mentioned fabric. The specific test methods are as follows: 1. Anti-ultraviolet property: Refer to the method of GB / T 18830—2009 "Evaluation of Anti-ultraviolet Performance of Textiles" to test the UPF value. Conduct parallel tests 4 times and take the average value, and then calculate the reduction value of the UPF value of Fabric 2, 5 - 10 compared to Fabric 1. The test results are shown in Table 1.

[0065] Table 1: Anti-ultraviolet 2. Air permeability: Refer to the method of GB / T5453-1997 "Textiles - Determination of Air Permeability of Fabrics" to test the air permeability (unit: mm / s). Conduct parallel tests 4 times and take the average value, and then calculate the reduction value of the air permeability of Fabric 2 - 10 compared to Fabric 1. The test results are shown in Table 2.

[0066] Table 2: Air permeability 3. Antibacterial property: Refer to GB / T 20944.3-2008 "Evaluation of Antibacterial Properties of Textiles - Part 3: Oscillation Method" to test the antibacterial properties of Escherichia coli ATCC 11229 and Staphylococcus aureus ATCC6538. Conduct parallel tests 4 times and take the average value, and calculate the reduction value of the antibacterial properties of Fabric 2, 5 - 10 compared to Fabric 1. The test results are shown in Table 3.

[0067] Table 3: Antibacterial property The present invention uses polyester fiber, bamboo fiber, and wool fiber as raw materials, blends them into warp and weft yarn semi-finished products, then weaves them to obtain a fabric base cloth, and then obtains a blended fabric through the first treatment and the second treatment; it combines the advantages of polyester fiber, bamboo fiber, and wool fiber. At the same time, through enzymatic hydrolysis treatment, the air permeability of the fabric is improved; a treatment liquid is also used to improve the antibacterial and anti-ultraviolet properties of the fabric.

[0068] According to the test results in Table 1-3, the fabric prepared by the present invention has excellent antibacterial effect, strong air permeability, and also has good ultraviolet resistance, showing good application prospects.

[0069] The present invention obtains the fabric through enzymatic hydrolysis treatment, effectively improving the fabric porosity and air permeability; and according to the tests of Fabric 1, 3-4 in the table, the use of both neutral protease and ficin in the system of the present invention has a synergistic effect in improving the air permeability effect.

[0070] The present invention uses titanium dioxide nanoparticles and zinc oxide nanoparticles to improve the ultraviolet resistance and antibacterial properties of the fabric. And long-chain and short-chain titanate coupling agents are used to modify the nanomaterials to improve their binding ability with fibers and to a certain extent improve their dispersion performance. And according to the test results of Fabric 1, 9-10, when the total amount of isopropyl triisostearoyl titanate and isopropyl tris(dioctyl pyrophosphato) titanate is kept unchanged and the ratio of the two is maintained at 1:1.5 - 2.5, the antibacterial and ultraviolet protection capabilities of the fabric obtained are stronger than those at other ratios. And the present invention uses a specific combination of isopropyl triisostearoyl titanate and isopropyl tris(dioctyl pyrophosphato) titanate, and the fabric obtained has better effects compared with other coupling agents, as can be obtained from the comparison of Fabric 1 and 8.

[0071] When the present invention uses titanium dioxide nanoparticles and zinc oxide nanoparticles to modify the fabric, sodium octenyl succinate starch and sulfobutyl ether-β-cyclodextrin are used in combination to improve their dispersion and binding ability with the fabric, thereby improving the antibacterial and ultraviolet resistance properties of the fabric. And when only one of sodium octenyl succinate starch and sulfobutyl ether-β-cyclodextrin is used while keeping the total amount unchanged, the effect of the obtained fabric is worse (i.e., the comparison between Fabric 6-7 and Fabric 1), that is to say, the present invention uses sodium octenyl succinate starch and sulfobutyl ether-β-cyclodextrin to synergistically improve the antibacterial and ultraviolet resistance capabilities of the fabric.
