Abstract

The invention relates to a preparation method of flame-retardant and anti-ultraviolet nylon fabric. The method comprises steps as follows: the nylon fabric with a clean surface is soaked in an aqueousdopamine solution, and dopamine modified nylon fabric is obtained; the dopamine modified nylon fabric is soaked in a silane coupling agent solution containing amino groups or sulfydryl groups and dried, and nylon fabric modified with the silane coupling agent is obtained; finally, the nylon fabric modified with the silane coupling agent is subjected to padding and finishing by a phosphorus-containing flame retardant solution with carboxyl groups. The flame-retardant and anti-ultraviolet nylon fabric prepared with the method is required to be protected, phosphorus content of the fabric is higher than or equal to 2.0wt%, nitrogen content is higher than or equal to 8.6wt%, silicon content is higher than or equal to 2.4wt%, and sulfur content is higher than or equal to 0wt%. The preparation method is simple and easy and has low requirement for equipment, the raw materials are environmentally friendly, the finally prepared fabric has excellent flame-retardant and anti-ultraviolet properties, the appearing time of first molten drop is longer than or equal to 23.1s, and the UPF value is larger than or equal to 200.

Description

technical field [0001] The invention relates to the field of functional finishing of textiles, in particular to a flame-retardant and ultraviolet-resistant nylon fabric and a preparation method thereof. Background technique [0002] As a synthetic fiber, nylon fiber (nylon) has the advantages of light weight, easy washing and quick drying, no fear of mildew, high strength and acid and alkali resistance, etc. It is widely used in the textile field. Nowadays, with the improvement of people's living standards, people's requirements for textiles are getting higher and higher. Nylon fiber is a thermoplastic fiber, because its melting point is lower than the ignition point, it is easy to shrink during the burning process and produces a large number of molten droplets. The molten droplets with flames may not only burn the skin, but may also ignite other flammable substances The flame spreads rapidly, causing a fire, resulting in a large amount of human and financial losses. There...
