Description

Technical Field

[0001] The invention relates to a graphene temperature-sensitive color-woven gauze fabric, and belongs to the field of gauze manufacturing. Background Art

[0002] With the application of gauze fabrics in textiles and clothing, it is increasingly favored by consumers, as it is soft, breathable and comfortable. However, in autumn and winter, gauze is especially used in home furnishings, but it is too breathable and lacks warmth retention, which makes it very limited in clothing products. Therefore, it is urgent to invent a gauze fabric with warmth retention to meet the market demand of consumers in autumn and winter.

[0003] Patent No. CN202110835787.3 discloses "Graphene heating fabric and production method", which provides a method of achieving graphene heating effect by soaking the fabric in an aqueous dispersion of graphene and manganese dioxide. In the above method, it is mainly implemented by padding during the finishing process of the fabric. The graphene is graphene oxide, which must be mixed with potassium permanganate and deionized water. There are restrictions on the requirements for additives, and for padding high-permeability gauze, the heating effect is not easy to achieve due to the gaps.

[0004] Patent No. CN201910737551.9 discloses "A graphene heating fabric and its preparation method", which provides a method of printing a graphene heating additive on a fabric by configuring a graphene printing paste. In the above method, the printing and dyeing process of the grey cloth is mainly used, which is different from the yarn-dyed weaving process of the present invention, and for the impregnated high-permeability gauze, the heating effect is not easy to achieve due to the gap.

[0005] Patent No. CN201810749199.6 discloses "Preparation method of graphene-modified antibacterial fiber and prepared graphene-modified antibacterial fiber and gauze", which provides a method of obtaining graphene-modified antibacterial fiber by planting and coating graphene on the fiber surface and then treating it by ultrasonic wave. The above method mainly introduces graphene antibacterial fiber and planting and coating on fiber technology. Summary of the invention

[0006] According to the background problem, the problem to be solved by the present invention is:

[0007] Develop a gauze fabric with warmth retention properties.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A graphene temperature-sensitive yarn-dyed gauze fabric, the preparation steps are:

[0010] (1) Yarn pretreatment: The pure cotton or cotton regenerated cellulose blended yarn is subjected to yarn pretreatment according to the yarn-dyed weaving process to obtain the yarn that has not been dried after being boiled, bleached and dyed;

[0011] (2) Use acetic acid to neutralize and clean the yarn, and adjust the environment to a weak acidic state;

[0012] (3) Graphene treatment: CERAMOND GRP, an anionic weakly acidic graphene additive that is easily soluble in water:

[0013] 5-10% owf, penetrant WA-M: 0.5-1% owf, bonding agent BINTEX S-200L: 0.5-1% owf are mixed evenly to obtain a working solution. After the colored yarn is soaked in the working solution at high temperature, the graphene additive is bonded to the yarn fiber;

[0014] (4) Wash the yarn once with soap, wash with hot water at 80℃ for 5 minutes, and rinse with cold water.

[0015] (5) drying treatment to bond the hydrophilic graphene additive to the yarn and fiber;

[0016] (6) The yarn is processed through sizing, weaving, singeing, desizing, tentering, physical air washing, tentering, and pre-shrinking to form a soft gauze fabric.

[0017] Preferably, the high-temperature immersion temperature of the working liquid in step (3) is 150° C., and the duration is 1-1.5 min.

[0018] Preferably, the drying temperature in step (5) is 90-100° C., the time is 20-30 min, and the treatment method is drying.

[0019] Preferably, the pH value of the working solution is 5.5-6.5.

[0020] Preferably, the pH of the weakly acidic environment in step (2) is 6.

[0021] Preferably, the graphene additive in step (3) is CERAMOND GRP produced by Daido Synthetic Chemical Industry Co., Ltd.

[0022] Preferably, the adhesive aid in step (3) is BINTEX S-200L produced by Daido Synthetic Chemical Industry Co., Ltd.

[0023] Preferably, the bonding aid in step (3) is WA-M produced by Shandong Lurui Fine Chemical Co., Ltd.

[0024] Graphene has good far-infrared radiation performance and will produce a far-infrared electromagnetic wave with a wavelength of 5.6 to 1000 microns. When the far-infrared wavelength of 8 to 15 microns is the same as the far-infrared wavelength close to body temperature of 36.5-37.0"C, it will produce a resonance absorption effect near the skin, causing the blood close to the skin to be heated, and the heated blood circulates throughout the body, causing the whole body to feel warm.

[0025] The graphene temperature-sensitive yarn-dyed gauze fabric is made by soaking the yarn in an anionic weakly acidic graphene aqueous solution after pretreatment through a yarn-dyed weaving process, soaking and drying, and then weaving and finishing. Since graphene with good far-infrared radiation performance is added, it will emit far-infrared rays under light sources such as sunlight or temperatures such as body temperature, which can produce a good heating effect and improve the poor warmth retention caused by the gaps in the gauze. The graphene temperature-sensitive gauze fabric has good far-infrared heating properties and is compatible with breathability.

[0026] The beneficial effects of the present invention are:

[0027] (1) The graphene heating working fluid of the present invention has a reasonable composition configuration and has good permeability to pure cotton and cotton regenerated cellulose fabrics, enabling the working fluid to quickly reach the interior of the yarn and be fixed to the fiber through an adhesive.

[0028] (2) The present invention can not only make the fiber have excellent long-lasting heating and warmth-retaining effect, but also have air permeability, thereby greatly improving the clothing performance of the gauze fabric.

[0029] (3) The gauze fabric woven by the graphene heating agent treated yarn has a temperature difference of ≥2°C between the gauze fabric processed with graphene and the gauze fabric without graphene treatment at the light heating effect of 5 minutes, and a temperature difference of ≥1.5°C after 10 washes. The effect is better as the square meter weight increases. BRIEF DESCRIPTION OF THE DRAWINGS
