Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a skin-friendly and comfortable blended fabric and a preparation method thereof. Background Art

[0002] With the continuous development of society and the improvement of people's living standards, people's requirements for "clothing" are getting higher and higher, especially for the comfort and functionality of clothing. Blended fabrics are made by mixing two or more fibers, using a specific spinning process to make blended yarns, and then making fabrics from blended yarns. Blended fabrics combine the advantages of fiber preparation, and the overall performance of the fabric is excellent. It is usually more advantageous than fabrics made of single fibers. It has good elasticity, good moisture absorption and other properties to meet various needs. In the field of clothing accessories, it can be used to make tops, trousers, bags, headwear, etc. In the field of household goods, it can be used to make sheets, quilt covers, tablecloths, curtains, etc. In the field of outdoor products, it can be used to make tents, sleeping bags, etc., and it is widely used.

[0003] Spandex fiber is a fiber with high stretchability and recovery, which can improve the dimensional stability and elasticity of the fabric. Cotton fiber is a natural fiber with good air permeability and moisture absorption. These two fibers can be used as fiber materials for preparing blended fabrics. However, due to the poor air permeability and moisture absorption of spandex fiber, the moisture absorption and air permeability of the blended fabric are poor. When the skin sweats, the sweat is difficult to evaporate, which affects the comfort level and may also cause bacteria to breed and multiply, produce odor, and even cause symptoms such as skin itching. In addition, when the weather is clear and the ultraviolet rays are strong, the blended fabric has poor UV resistance. On the one hand, the fabric will age and fade if exposed to ultraviolet rays for a long time, which greatly shortens the service life of the fabric. On the other hand, the poor UV resistance of the fabric means poor sun protection effect, which may also cause the skin to be tanned and sunburned. It is very necessary to improve the antibacterial and anti-ultraviolet properties of blended fabrics. The patent with publication number CN117604703B discloses a blended fabric weaving method, comprising the following steps: S1, coating modified nylon fiber with spandex fiber to obtain warp yarn; blending polyvinyl alcohol fiber with spandex fiber to obtain weft yarn; S2, weaving the warp yarn and the weft yarn with plain weave to obtain grey cloth; the grey cloth is de-woven, washed, dried, and shaped to obtain fabric; the blended fabric prepared by the invention has significant air permeability and moisture permeability, light texture, antibacterial and mildew-proof, comfortable and skin-friendly, but the antibacterial property of the patent is not reflected, and the anti-ultraviolet property is not taken into consideration. For this reason, the present invention provides a skin-friendly and comfortable blended fabric with excellent antibacterial and anti-ultraviolet properties, good moisture absorption and air permeability, durability, and broad application prospects. Summary of the invention

[0004] In order to solve the problems mentioned in the background technology, the object of the present invention is to provide a skin-friendly and comfortable blended fabric and a preparation method thereof.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A method for preparing a skin-friendly and comfortable blended fabric comprises the following steps:

[0007] The first step: blending spandex fiber and cotton fiber in proportion to obtain blended yarn;

[0008] Step 2: Use the blended yarn as warp and weft yarn and weave with plain weave to form grey cloth;

[0009] Step 3: Place the blank in a washing machine for washing, with a bath ratio of 1:30-50, the water temperature is raised to 40-60°C, and the washing time is 30-60 minutes;

[0010] Step 4: Mix 65-75 parts by weight of water, 3-8 parts of sodium dodecylbenzene sulfonate, 12-14 parts of functional additive components, and 8-10 parts of inorganic modified materials, then raise the temperature to 40-60° C., stir for 1-3 hours, and obtain a modified finishing liquid;

[0011] Step 5: Soak the washed grey cloth in the modified finishing liquid, raise the temperature to 40-50℃, and oscillate for 60-90min. Then take out the grey cloth and squeeze it through a small rolling mill, dry it with hot air at 60-70℃, and then bake it at 100-120℃ for 3-6min to obtain the blended fabric.

[0012] Furthermore, in the first step, the ratio of the spandex fiber to the cotton fiber is 1-1.5:1.

[0013] Furthermore, in the fourth step, the preparation method of the functional additive component comprises the following steps:

[0014] Step S1: adding wool keratin to N,N-dimethylformamide, mixing evenly, adding natural antibacterial substances and alkaline catalysts, introducing nitrogen protection, stirring at room temperature for 3-5 hours, centrifuging at 800-1000 r / min for 10-15 minutes, collecting the product, washing, and drying to obtain modified wool keratin;

[0015] Step S2: Add the modified wool keratin and glycerin into deionized water, stir and mix evenly, and after the wool keratin fully absorbs water, keep it in a low temperature environment of -20°C for 12-16 hours, take it out and put it into a freeze dryer for freeze drying to obtain a functional added component.

[0016] By adopting the above technical scheme, under the action of alkaline catalyst, the amino group in the wool keratin structure and the aldehyde group in the structure of natural antibacterial substances can undergo Schiff base reaction to obtain modified wool keratin, and the modified wool keratin with a porous structure is obtained by freeze-drying, which is the functional added component. The functional additive component prepared by the present invention modifies wool keratin and introduces natural antibacterial substances in a chemically bonded manner. The natural antibacterial substances have a broad-spectrum antibacterial effect, and the generated Schiff base structure also has an antibacterial effect, thereby giving the blended fabric excellent antibacterial properties, preventing bacteria from growing and multiplying in the blended fabric and causing adverse effects on the skin, making the blended fabric more hygienic and safe, and effectively preventing the blended fabric from being washed multiple times during long-term use, resulting in excessive loss of antibacterial substances and a significant reduction in antibacterial properties, so that the blended fabric can be long-lastingly antibacterial. In addition, the wool keratin in the functional additive component has excellent skin-friendliness, which can reduce the discomfort caused by friction between the fabric and the skin during use, and the porous structure of the functional additive component can make the blended fabric better absorb moisture and be breathable when the human body produces sweat or dissipates heat, which is beneficial to air circulation, keeps the skin dry, improves comfort, creates a dry skin environment and reduces the possibility of bacterial growth.

[0017] Furthermore, in step S1, the natural antibacterial substance is any one of syringaldehyde, vanillin or perillaldehyde.

[0018] Furthermore, in step S1, the alkaline catalyst is triethylamine or pyridine.

[0019] Furthermore, in the fourth step, the method for preparing the inorganic modified material comprises the following steps:

[0020] Step A: dispersing coconut shell fiber in dimethyl sulfoxide to form a uniform suspension, adding 2,3-dimercaptosuccinic acid and a catalyst, raising the temperature to 90-100° C., stirring for 2-4 hours, filtering, washing, and drying to obtain modified coconut shell fiber;

[0021] Step B: Disperse the modified coconut shell fiber in N,N-dimethylformamide to form a uniform suspension, add an ultraviolet absorber and a photoinitiator, irradiate with an ultraviolet lamp with a wavelength of 365nm for 1-3h, separate the product, wash, and dry to obtain an inorganic modified material.

[0022] By adopting the above technical scheme, the active hydroxyl groups on the surface of the coconut shell fiber can undergo an esterification reaction with the carboxyl groups in the structure of 2,3-dimercaptosuccinic acid under the action of a catalyst to obtain modified coconut shell fiber with a thiol group. Through ultraviolet light irradiation and the action of a photoinitiator, the thiol groups on the surface of the modified coconut shell fiber undergo a thiol-ene click reaction with the olefinic groups in the structure of the ultraviolet absorber to obtain an inorganic modified material. The inorganic modified material prepared by the present invention introduces an ultraviolet absorber on the surface of coconut shell fiber. On the one hand, the large micropore area of ​​coconut shell fiber can be utilized, the air permeability is good, the adsorption is strong, the sweat accumulation can be reduced, the skin is kept dry, and the wearing comfort is high. The inorganic modified material also contains a hydrophilic carboxyl group, so that the blended fabric is comfortable, breathable and skin-friendly to wear, and has the function of synergistically improving the comfort with the functional added component. On the other hand, the ultraviolet absorber has excellent ultraviolet absorption efficiency, can improve the sunscreen ability of the blended fabric, reduce the damage of ultraviolet rays to the blended fabric, avoid the embrittlement phenomenon of the fabric, extend the service life of the blended fabric, protect the skin from the damage of ultraviolet rays, and avoid being sunburned. At the same time, the ultraviolet absorber can be grafted with the coconut shell fiber to effectively avoid excessive loss of the ultraviolet absorber after repeated washing, so that the blended fabric has a long-term ultraviolet resistance ability.

[0023] Furthermore, in step A, the catalyst is trifluoromethanesulfonic acid or p-toluenesulfonic acid.

[0024] Furthermore, in step B, the ultraviolet absorber is 4-propyleneoxy-2-hydroxybenzophenone or 2-acrylic acid-2-(4-benzoyl-3-hydroxyphenoxy)ethyl ester.

[0025] Furthermore, in step B, the photoinitiator is benzoin dimethyl ether or benzoin isobutyl ether.

[0026] A skin-friendly and comfortable blended fabric is prepared by adopting the preparation method.

[0027] Beneficial effects of the present invention:

[0028] The blended fabric prepared by the present invention has excellent moisture absorption and air permeability, can reduce the discomfort caused by the friction between the skin and the fabric, reduce the accumulation of sweat, keep the skin dry, and has high wearing comfort and good skin-friendliness; the blended fabric has excellent antibacterial performance, can effectively inhibit the growth and reproduction of bacteria, avoid adverse effects on the skin, make the blended fabric more hygienic and safe, and the antibacterial substances will not be lost too much after repeated washing, and can be long-lasting antibacterial; the blended fabric has excellent anti-ultraviolet performance, can reduce the damage of ultraviolet rays to the blended fabric, extend the service life of the blended fabric, and improve the sun protection ability of the blended fabric, protect the skin, and avoid being tanned and sunburned, and the ultraviolet absorbing substances will not be lost too much after repeated washing, and can be long-lasting anti-ultraviolet, therefore, the blended fabric prepared by the present invention has broad application prospects.
