Problems solved by technology

For example, the Chinese patent document CN102392346B discloses a finishing method for nano-scale anti-ultraviolet and anti-bacterial hydrophobic fabrics, which is specifically processed by using nano-zinc sol and self-prepared long-chain aliphatic water repellent in the finishing solution. Textiles with excellent hydrophobic properties, UV resistance and antibacterial properties have been obtained, but the washing durability of textiles has not been solved

Embodiment 1

[0064] Prepared weight 68g / m 2 Thin polyester woven fabric (both warp and weft yarns are 50D-48f-DTY), put it into UV absorber A3% o.w.f., stilbene type fluorescent whitening agent 0.5% o.w.f. and diffusion accelerator 3% benzyl benzoate o.w.f. In the treatment solution formed (bath ratio 1:20), the temperature was raised to 90°C for 60 minutes of bath finishing, and then reduction cleaning was performed according to the conventional method (30% NaOH solution 2g / L, hydrosulfite 2g / L, 80℃×20 minutes), and finally 130℃×2 minutes for drying;

[0065] Then use 50g / L of water-repellent agent (C6 fluorine series), 10g / L of bridging agent isocyanate, and 10g / L of penetrating agent isopropanol to perform one-dipping and one-rolling water-repellent processing. Dry for 2 minutes and heat-set at 170° C. for 1 minute to obtain the polyester textile of the present invention. Its properties are detailed in Table 1.

Embodiment 2

[0067] Prepare gram weight 30g / m 2 Thin polyester woven fabric (both warp and weft yarns are 20D-36f-DTY), put it into UV absorber C5%o.w.f., diffusion accelerator benzyl benzoate 2%o.w.f., coumarin type fluorescent whitening agent 0.5%o.w.f. Mix evenly, bath ratio: 1:20; heat up to 100°C for 40 minutes in the bath, and then perform reduction cleaning according to the conventional method (30% NaOH solution 2g / L, hydrosulfite 2g / L, 80°C×20 minutes ), and finally dry at 130°C for 2 minutes.

[0068] Then use 100g / L of water-repellent agent (C6 fluorine series), 15g / L of bridge-linking agent polyurethane, and 5g / L of penetrating agent fatty alcohol polyoxyethylene ether to carry out one-dipping and one-rolling water-repellent processing, and the rolling rate is 60%. Dry at 120°C for 2 minutes and heat set at 160°C for 2 minutes to obtain the polyester textile of the present invention. Its properties are detailed in Table 1.

Embodiment 3

[0070] Prepared weight 60g / m 2 Thin polyester woven fabric (both warp and weft yarns are 40D-48f-DTY), put it into UV absorber B1% o.w.f., diffusion accelerator 2% o.w.f. benzyl alcohol, phthalimide type fluorescent whitening agent 1% o.w.f. Mix evenly, bath ratio: 1:30; heat up to 110°C for 30 minutes in the bath, and then perform reduction cleaning according to the conventional method (30% NaOH solution 2g / L, hydrosulfite 2g / L, 80°C×20 minutes), and finally dry at 130°C for 2 minutes.

[0071] Then use 30g / L of water repellent agent (C8 fluorine series), 20g / L of bridging agent isocyanate, and 8g / L of penetrating agent isopropanol to perform one-dipping and one-rolling water-repellent processing. Dry for 3 minutes and heat-set at 180° C. for 1 minute to obtain the polyester textile of the present invention. Its properties are detailed in Table 1.

Abstract

The invention discloses a water-repellent anti-UV textile, a production method and an application thereof. The textile is a machine-woven fabric which is composed of 100% polyester fibers and is lower than 80 g / m<2> in gram weight. The textile is 5-grade in initial-stage water-repellent property. According to JISL0217103, after being washed in home for 20 times, a test result proves that the textile reaches more than 40 in UV protective coefficient according to AS / NZS4399-1996 standard. The polyester fiber is lower than 50 deniers in fineness. The polyester fiber internally at least contains an UV absorber and a flourescent brightener, the surface of more than 80% of the polyester fibers is coated with resin film. A diffusion promoter increases the entrance amount of the UV absorber and the flourescent brightener into the fibers, so that the textile has excellent anti-UV performance. Anti-UV treatment is carried in a dyeing step in a one-bath manner, so that the production method is free of addition of process steps and further save resources. The textile has an excellent water-repellent effect.

Description

technical field [0001] The invention belongs to the fields of textiles and materials, and in particular relates to a water-repellent and ultraviolet-resistant textile mainly containing polyester fibers. Background technique [0002] With the maturity of ultra-fine fiber spinning and weaving technology, the proportion of ultra-thin chemical fiber textiles in sports and leisure clothing is also increasing. Since this kind of clothing is mostly worn and used outdoors and needs to cope with various weathers, it is required to have certain UV resistance and water repellency. [0003] The fine-denier polyester textiles in ultra-thin chemical fiber textiles are not only soft to the touch, but also have good wrinkle resistance and good storage properties. They are deeply loved by consumers and widely used in outdoor sportswear. Although the benzene rings in polyester fibers and the aromatic amino acids in wool protein molecules have a strong absorption capacity for light with a wav...
