Description

Technical Field

[0001] The present invention relates to the field of textile fabrics, and particularly to an ice-sensing and ultraviolet-resistant functional fabric and a preparation process thereof. Background Art

[0002] In recent years, due to the large amount of substances such as Freon emitted in human production and life, the protective ozone layer of the earth has become thinner and sparser, and the amount of ultraviolet radiation reaching the ground has increased. More and more diseases are caused by excessive ultraviolet radiation. Therefore, the industry generally conducts anti-ultraviolet finishing on summer fabrics to reduce the harm to human skin under strong ultraviolet conditions in summer. Among them, having a cool feeling in environments such as hot weather has always been a basic requirement for a comfortable life, and the cool fabric touch can also enable consumers to have a more comfortable experience. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an ice-sensing and ultraviolet-resistant functional fabric and a preparation process thereof. The obtained fabric is not only soft and comfortable, has a low UVA transmittance, but also can achieve an ice-sensing effect.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions: An ice-sensing and ultraviolet-resistant functional fabric is woven from modified polyester warp and modified polyester weft, and the fabric is impregnated and rolled with an anti-ultraviolet finishing solution; wherein the anti-ultraviolet finishing solution comprises functional benzoyl methane, polyurethane emulsion, N, N-dimethylformamide and butyl acetate in a weight ratio of 1:3:1:1.

[0005] A preparation process of an ice-sensing and ultraviolet-resistant functional fabric comprises the following steps: Winding the modified polyester warp and modified polyester weft, sectional warping, threading, weaving, cold stacking, impregnating and rolling with an ice-sensing finishing solution, impregnating and rolling with an anti-ultraviolet finishing solution, drying and baking to obtain the ice-sensing and ultraviolet-resistant functional fabric.

[0006] Preferably, the preparation process of the modified polyester warp and modified polyester weft comprises the following steps: Immerse the polyester warp and polyester weft in the anti-ultraviolet finishing solution for 24 - 48 h, rinse thoroughly and then dry to obtain the modified polyester warp and modified polyester weft.

[0007] Preferably, the preparation method of the ice-sensing finishing solution is: Mix lemon essential oil, chitosan quaternary ammonium salt, methyl methacrylate, dimethyl carbonate, ice-sensing silicone oil and polyacrylic acid emulsion to obtain the ice-sensing finishing solution.

[0008] Preferably, the weight ratio of the lemon essential oil, quaternary ammonium salt of chitosan, methyl methacrylate, dimethyl carbonate, ice-sensing silicone oil and polyacrylic acid emulsion is 1:2:1:2:4:5.

[0009] Preferably, the preparation method of the polyacrylic acid emulsion is as follows: Mix ammonium persulfate, sodium alkyl sulfate, monomer acrylic acid and isopropanol, and stir at 70 °C for 2-3 h to obtain the polyacrylic acid emulsion.

[0010] Preferably, the weight ratio of ammonium persulfate, sodium alkyl sulfate, monomer acrylic acid and isopropanol is 1:2:4:6.

[0011] Preferably, the preparation method of the anti-ultraviolet finishing solution is as follows: Mix functional dibenzoylmethane, polyurethane emulsion, N,N-dimethylformamide and butyl acetate, and stir at room temperature for 20-24 h to obtain the anti-ultraviolet finishing solution.

[0012] Preferably, the preparation method of the functional dibenzoylmethane is as follows: Mix dibenzoylmethane, polyvinylpyrrolidone, copper acetate and ethanol solution with a volume fraction of 85%, stir for 1-2 h, and dry to obtain functional dibenzoylmethane.

[0013] Preferably, the weight ratio of dibenzoylmethane, polyvinylpyrrolidone, copper acetate and ethanol solution is 1:2:1:4.

[0014] In the present invention, through the crosslinking of the emulsion and the ice-sensing silicone oil, it aggregates on the fiber surface, improving the fusion degree of the ice-sensing silicone oil on the fiber. Since the ice-sensing silicone oil is loaded by the emulsion, it can also be inserted into the voids inside the fiber to fill the fiber voids, thereby endowing the system with better adsorption and loading of the ice-sensing silicone oil. In addition, the emulsion crosslinks with the functional dibenzoylmethane to form an anti-ultraviolet solution, which aggregates on the fiber surface, first modifying the fiber against ultraviolet rays, and finally performing overall anti-ultraviolet padding on the fabric, further locking the diffusion of the ice-sensing silicone oil while also better locking the anti-ultraviolet solution on the fiber surface and inside. In this way, it can absorb or reflect ultraviolet rays, prevent or limit the penetration of ultraviolet rays into the fiber interior, and at the same time, the functional dibenzoylmethane is loaded with copper ions, which can absorb high-energy ultraviolet light, thereby enhancing the anti-ultraviolet performance of the fabric.
