Embodiment 1

[0033] Get 2g of cashmere yarn and put into it containing 24g / L of AG-710 organic fluororesin from Japan Asahi Glass Co. L, in the water system of magnesium chloride 0.1g / L and isopropanol 20g / L, bath ratio is 1: 20, soaks 30min at 40 ℃, squeezes liquid then, makes liquid squeeze rate 70%, puts into oven, at 90 Pre-bake at ℃ for 5 minutes, and continue to bake at 110℃ for 1.5 minutes to obtain nanometer self-cleaning cashmere yarn.

Embodiment 2

[0035] Cut cashmere knitwear into 5cm square samples, and at room temperature, use 20g / L of zinc oxide containing 70g / L of Japanese Asahi Glass AG-710 organic fluorine resin, 20g / L of zinc oxide with an average particle size of 50nm, and 20g of vinyl tri-tert-butyl peroxysilane / L water system to spray the above-mentioned low-temperature air plasma-treated fabric, then put it into an oven, pre-bake at 70°C for 30min, and continue to bake at 100°C for 4min to obtain nanometer self-cleaning cashmere knitwear.

Embodiment 3

[0037] Cut cashmere worsted fabric into 5cm square samples, put 30g / L of organic fluorine resin containing AG-7000 from Japan Asahi Glass Co., Ltd., 30g / L of titanium oxide with an average particle size of 30nm, and 50g / L of vinyltriethoxysilane, In the water system of melamine resin 3g / L, magnesium chloride 0.1g / L and isopropanol 30g / L, bath ratio is 1: 60, dipped at 40 ℃ for 30min, then squeezed liquid, make squeezed liquid rate 80%, put into Oven, pre-bake at 90°C for 10 minutes, and continue to bake at 130°C for 2 minutes to obtain nanometer self-cleaning cashmere worsted fabric.

Abstract

The invention relates to a self-cleaning nano cashmere or products and making method, where the self-cleaning nano cashmere or products is obtained by adopting organic fluorin finishing agent containing nano inorganic solid particles to process the cashmere or products by dipping, coating or spraying. The organic fluorin finishing agent is a water system containing organic fluorin resin 10-70g / L, nano solid particle 5-30g / L, silane coupling agent 0-50g / L, cross-linking agent 0-7g / L, magnesium chloride 0-0.1g / L and isopropanol 0-30g / L. The self-cleaning nano cashmere or products has super -hydrophobic and -oleophobic property, i.e. not stained with both water and oil, thus achieving the self-cleaning purpose.

Description

technical field [0001] The invention belongs to the field of textile processing, and in particular relates to nano self-cleaning cashmere or products and their preparation methods. Background technique [0002] Cashmere has the reputation of "the crown of fiber" and "soft gold". The world's cashmere production is less than 1% of the total wool production, and it is a precious raw material for the wool spinning industry. Compared with wool, cashmere has thinner fibers, shorter length, and slightly weaker strength. Compared with wool, cashmere is smoother, softer, lighter, delicate, warm, and comfortable to wear. However, cashmere products will be deformed due to mutual impact and friction during the washing process, which affects their wearing performance. [0003] With the improvement of people's awareness of environmental protection and energy conservation, people have carried out research on self-cleaning technology of materials. For example, Japa...
