Description

TECHNICAL FIELD

[0001] The present application relates to a skin-friendly antibacterial cool lining cloth and a preparation method thereof. BACKGROUND

[0002] With the improvement of people's living standards and the increasing demand for clothing comfort, functional textiles have gradually become the focus of market attention. In summer or high-temperature environment, the air permeability and coolness performance of clothes are particularly important, and as a lining material that adheres to the skin, its comfort, antibacterial property and skin-friendliness directly affect the wearing experience and health. Therefore, it is of great practical significance to develop a lining material that has good coolness, antibacterial property and skin-friendliness.

[0003] At present, the common lining materials on the market are mostly made of pure cotton, polyester or their blended fabrics. Although they meet the basic wearing needs to some extent, they still have deficiencies in functionality and comfort. For example, although traditional cotton lining has good moisture absorption and skin-friendliness, its thermal conductivity is poor, making it difficult to achieve the cooling effect of rapid heat dissipation. While polyester synthetic fibers have good strength and wear resistance, due to their hydrophobic properties, they are prone to retain sweat, causing discomfort and even breeding bacteria, affecting the skin health of the wearer.

[0004] To improve the above problems, in recent years, some researches have introduced cool fibers (such as jade fiber, ice silk fiber, etc.) into the fabric to improve its thermal conductivity and instantaneous contact coolness. In addition, the application of antibacterial finishing technology is also relatively widespread, including silver ion antibacterial, chitosan coating, etc. These technologies can inhibit bacterial growth to some extent and improve the hygiene performance of the fabric. However, existing technologies often focus on the improvement of a single function, lack of systematic optimization of the synergistic effect of coolness, antibacterial property and skin-friendliness, and some processing technologies are complex and costly, which is not conducive to large-scale industrial production.

[0005] At the same time, with the enhancement of consumers' environmental awareness, higher requirements for the safety and ecological friendliness of textiles are put forward. Traditional chemical antibacterial agents may have certain toxic side effects, and long-term use may also cause drug resistance problems. Therefore, it is urgent to develop a safer, more efficient and multifunctional integrated lining material that can ensure good coolness while considering antibacterial performance and skin-friendliness, and adapt to the development trend of modern green manufacturing. SUMMARY

[0020] Further, the preparation steps of the high-dispersed boron nitride nanosheets are as follows: hexagonal boron nitride is heated to 1000 DEG C in a muffle furnace for 4 h, and naturally cooled to room temperature to obtain oxidized hexagonal boron nitride; 8 parts by mass of the oxidized hexagonal boron nitride is added into a mixture of 170 parts by mass of deionized water and 12-13 parts by mass of 1-ethyl-3-methylimidazolium hydroxide, ultrasonic treatment is carried out for 7-9 h, centrifugal separation is carried out at 7500-8500 rpm for 9-11 min, and the precipitate is vacuum dried at 55-65 DEG C to prepare the high-dispersed boron nitride nanosheets.

[0021] Further, the preparation steps of the emulsifier solution are as follows: 0.64-0.65 parts by mass of sodium dodecyl sulfate, 0.43-0.44 parts by mass of fatty alcohol polyoxyethylene ether and 36 parts by mass of deionized water are uniformly mixed to obtain the emulsifier solution.

[0022] Further, the initiator solution: 0.14-0.16 parts by mass of potassium persulfate is dissolved in 9 parts by mass of deionized water to obtain the initiator solution.

[0023] By adopting the technical scheme, the present application has the following beneficial effects:

[0024] (1) The mint fiber is a regenerated cellulose fiber, has good moisture absorption and air permeability, and has strong cool feeling when wearing, has excellent antibacterial properties, and also provides good wearing performance; the tencel fiber is a regenerated cellulose fiber, has antibacterial and skin-friendly softness; the modal fiber is also a regenerated cellulose fiber, can be naturally degraded, is friendly to the environment, and has good comfortable skin-friendly and air permeability and moisture absorption better than cotton fiber, the skin-friendly antibacterial cool lining fabric of the present application is obtained by blending and weaving the mint fiber, the tencel fiber and the modal fiber to obtain an antibacterial lining fabric, and then carrying out two-dip-two-pad in the cool finishing liquid, so that the obtained skin-friendly antibacterial cool lining fabric has good antibacterial property, fabric cool feeling and skin-friendly property.

[0025] (2) The cool finishing liquid of the present application mainly includes the following raw material components by weight fraction: 0.186-0.188 parts by mass of high-dispersion boron nitride nanosheets, 8-10 parts by mass of butyl acrylate, 5-7 parts by mass of methyl methacrylate, 0.71-0.73 parts by mass of vinyl trimethoxysilane, 0.26-0.34 parts by mass of hydroxyethyl methacrylate, 0.19-0.57 parts by mass of 4-acetylphenyl acrylate, 5.5 parts by mass of an emulsifier solution, 9.14-9.16 parts by mass of an initiator solution, and 0.2-0.3 parts by mass of an antioxidant. The butyl acrylate, methyl methacrylate, vinyl trimethoxysilane, hydroxyethyl methacrylate, and acetylphenyl acrylate are used as reaction monomers to perform emulsion polymerization, thereby obtaining an acrylate polymer with high adhesion. The high-dispersion boron nitride nanosheets with coolness are stably attached to the surface of the antibacterial lining cloth.

[0026] (3) The antioxidant used in the present application is eugenol. Eugenol is a compound naturally occurring in plants such as cloves, and can also be obtained by artificial synthesis or extraction from plant essential oils. Due to its wide source channel, the raw material is easy to obtain, which is conducive to large-scale production and application. As a natural ingredient, eugenol has good biodegradability and is environmentally friendly. Compared with some traditional synthetic antioxidants such as BHT and BHA, it has lower ecological toxicity, which meets the current trend of green chemistry and sustainable development.

[0027] (4) Boron nitride has high thermal conductivity, good chemical stability, excellent electrical insulation, and low thermal expansion coefficient, and is commonly used as a thermal interface material in the nuclear industry, electronics, chemical industry, and other fields. In the field of textiles and clothing, it can be used as a cool functional finishing agent. The introduction of boron nitride in the present application can significantly improve the coolness performance of the skin-friendly antibacterial cool lining cloth. However, the dispersion of boron nitride nanosheets is poor and easy to agglomerate. The introduction of 1-ethyl-3-methyl imidazole hydroxide can effectively improve the dispersion of boron nitride nanosheets in the finishing liquid, thereby preventing the boron nitride nanosheets from falling off from the skin-friendly antibacterial cool lining cloth.

[0028] (5) During the finishing process of the antibacterial lining cloth using the cool finishing liquid, the acetylphenyl in the acrylate polymer in the finishing liquid undergoes a Claisen-Schmidt condensation reaction with the antioxidant eugenol under the catalysis of 1-ethyl-3-methyl imidazole hydroxide on the surface of the high-dispersion boron nitride nanosheets, forming a double aromatic ring conjugated system connected by α,β-unsaturated carbonyl groups. This system can effectively absorb ultraviolet rays, and the conjugated structure can convert ultraviolet light energy into heat energy or other harmless energy forms through π-π* electron transition, thereby giving the skin-friendly antibacterial cool lining cloth good sunscreen performance.
