[0038] Measure 50 mL of distilled water, add 1.0 g of BPTCA-N and 0.05 g of JFC, and adjust the pH of the solution to 6.0 with acetic acid to obtain a finishing working solution with an effective concentration of BPTCA-N of 20 g / L.

[0039] The pretreated biomass fiber PA56 fabric was immersed in the finishing working solution at a bath ratio of 1:20, and after two dips and two rollings, the nip rate was 70%, and then pre-baked at 90 °C for 3 minutes, and baked at 140 °C for 1.5 minutes. min.

Embodiment 3

[0041] Weigh 2.5g of biomass fiber PA56 fabric and place it in the pretreatment solution. In the pretreatment solution, the concentration of hydrogen peroxide is 10g / L, the concentration of penetrant JFC is 3g / L, the high-efficiency refining agent NC is 10g / L, and the sodium carbonate is 10g. / L, treated at 60℃ for 45min, washed with clean water, and air-dried naturally.

[0042] Measure 50 mL of distilled water, add 1.5 g of BPTCA-N and 0.1 g of JFC, and adjust the pH of the solution to 6.0 with acetic acid to obtain a finishing working solution with an effective concentration of BPTCA-N of 30 g / L.

[0043] The pretreated biomass fiber PA56 fabric was immersed in the finishing working solution at a bath ratio of 1:15, and after one dipping and one rolling, the overage rate was 85%, and then pre-baked at 80 °C for 2 minutes, and baked at 140 °C for 1 minute. .

Abstract

The invention discloses a preparation method of an ultraviolet-proof antibacterial bio-fiber PA56 fabric, including the steps of 1), pre-treating the bio-fiber PA56 fabric in a pre-treatment solutionat the temperature of 40-80 DEG C for 15-45 minutes; 2), preparing a benzophenone cationic-compound aqueous solution with a certain concentration, adding a certain quantity of penetrant, regulating the pH value of the solution by ethylic acid, to obtain a finishing treatment solution; 3), immersing the pre-treated bio-fiber PA56 fabric in the finishing treatment solution prepared in the step 2), performing padding, preliminary drying and baking to obtain the ultraviolet-proof antibacterial bio-fiber PA56 fabric. The preparation method can prepare the bio-fiber PA56 fabric having ultraviolet protection and photoinduced antibacterial property. The bio-fiber PA56 fabric has novel structure, and can be applied to the field of clothing fabrics and medical materials; the preparation method is simple and easy to operate without needing of special equipment.

Description

technical field [0001] The invention relates to the preparation and application of a biomass fiber PA56 fabric with anti-ultraviolet and antibacterial properties, and belongs to the technical field of textile materials. Background technique [0002] Nylon fibers are favored by consumers because of their good mechanical properties, hydrophilic properties, and dyeing properties, and are widely used in the textile and clothing industries. At present, petroleum-based synthetic PA6 and PA66 are the most common applications. With the increasing scarcity of petroleum resources, vigorously developing renewable fibers will help expand the source of textile raw materials and achieve sustainable development of the textile industry. Bio-based fiber PA56 is polymerized from bio-based pentamethylene diamine and petroleum-based adipic acid. The source of pentamethylene diamine is the product of decarboxylation of lysine, and it is a homologue with hexamethylene diamine. Fiber PA56. Comp...
