Embodiment 1

[0019] Step 1: Surface pretreatment: first wash the polyester fabric to remove impurities on its surface, then carry out alkali treatment on the washed fabric, pad the fabric with 400g / L NaOH solution, the liquid retention rate is 100%, and then Steam at 100°C for 2 to 5 minutes, take it out, wash and dry it, and obtain an alkali-treated polyester fabric;

[0020] Step 2: Soak the alkali-treated polyester fabric in 0.1-10 g / L polydimethyldiallyl ammonium chloride (PDDA) aqueous solution for 10 minutes, and absorb a layer of PDDA on the surface of the fabric; Stable adsorbed PDDA, washed and dried. Take 0.1g of ZnO / SiO 2 The core-shell structure composite particles (core-shell mass ratio of the core-shell structure composite particles: 1-30) were dispersed in 50ml deionized water after ultrasonication for 10 minutes to obtain a stable dispersion. The polyester fabric treated with alkali and adsorbed polymer electrolyte on the surface was soaked in ZnO / SiO 2 In the dispersion...

Embodiment 2

[0023] Step 1: First, carry out alkali treatment on the cleaned fabric, pad the fabric with 400g / L NaOH solution, the liquid retention rate is 100%, then steam at 100°C for 3 minutes, take it out, wash and dry it, and obtain the alkali treated polyester fabric;

[0024] Step 2: Soak the alkali-treated polyester fabric in 0.1-10g / L polydimethyldiallylammonium chloride (PDDA) aqueous solution for 10 minutes, and form a layer of PDDA on the surface of the fabric; wash with deionized water to remove the surface Unstabilized adsorbed PDDA was then dried. Soak the polyester fabric with a layer of PDDA adsorbed on the surface in 0.1-10g / L sodium polystyrene sulfonate (PSS) aqueous solution for 10 minutes, and adsorb a layer of PSS on the surface of the fabric; wash with deionized water to remove the PSS that is not stably adsorbed on the surface, Dry after washing; repeat the above steps to adsorb another layer of PDDA on the surface of the fabric; take 0.1g ZnO / SiO 2 The core-shel...

Embodiment 3

[0027]Step 1: First, carry out alkali treatment on the cleaned fabric, pad the fabric with 400g / L NaOH solution, the liquid retention rate is 100%, and then steam it at 100°C for 3 minutes, take it out, wash and dry it, and obtain the alkali Treated polyester fabric.

[0028] Step 2: Soak the alkali-treated polyester fabric in 0.1-10g / L polydimethyldiallylammonium chloride (PDDA) aqueous solution for 10 minutes, and form a layer of PDDA on the surface of the fabric; wash the fabric with deionized water PDDA not stably adsorbed on the surface should be dried after washing. Soak the polyester fabric with a layer of PDDA adsorbed on the surface in 0.1-10g / L sodium polystyrene sulfonate (PSS) aqueous solution for 10 minutes, and adsorb a layer of PSS on the surface of the fabric; wash with deionized water to remove the PSS that is not stably adsorbed on the surface of the fabric , after washing and drying; repeat the above steps to adsorb another layer of PDDA on the surface of t...

Abstract

The invention provides a preparation method of a superhydrophobic ultraviolet resistant textile, which comprises the steps that: first, the surface of the textile is pre-treated; then a micro-particle in a core-shell structure with ultraviolet absorption action is loaded on the surface of the textile which is pre-treated so as to improve the surface roughness of the textile; and finally a low-surface energy substance is adopted to treat the textile which is loaded with the micro-particle in the core-shell structure. A contact angle between the textile which is prepared through the method and a water drop is more than 150 degrees, and the textile has stable superhydrophobic performance, and simultaneously has excellent ultraviolet protection performance.

Description

technical field [0001] The invention relates to a preparation method of functional textiles, in particular to a preparation method of superhydrophobic anti-ultraviolet textiles. Background technique [0002] Super-hydrophobic anti-ultraviolet functional textiles not only have important applications in industrial production, medical and military products, but also have a wide range of applications in daily life, such as sunny and rainy life umbrellas, beach umbrellas, advertising umbrellas, open-air tents, advertising flags and Advertising fabrics, etc. [0003] In order to utilize the self-cleaning effect of the superhydrophobic surface, Chinese patent CN 1242114C discloses nano self-cleaning cashmere or products and its preparation method, Chinese patent CN 1277019C discloses nano self-cleaning silk and products, and Chinese patent CN 1824884A discloses nano-functional The preparation method of the self-cleaning suit fabric and ready-made clothing products of non-toxic mat...
