Problems solved by technology

However, in the flame retardant finishing of textiles, most flame retardants are phosphorus-containing flame retardants, and the use of such flame retardants has caused great pressure on the environment
Moreover, the flame retardant treatment method of textiles is complicated, and the wash fastness is poor. Therefore, the combination of superhydrophobicity and flame retardancy can greatly reduce the need for textile washing, and provide a solution for the dissolution and leaching of flame retardant components during the washing process. a practical path
However, there is no report on the use of natural polyphenols to explore and prepare superhydrophobic, UV-resistant, and flame-retardant silk fabrics that are cheap, environmentally friendly, and simple in process.

Abstract

The invention provides a preparation method of a super-hydrophobic anti-ultraviolet flame-retardant silk fabric. The preparation method comprises the following steps: soaking the silk fabric in an acidic buffer solution; adding natural polyphenol and a laccase catalyst into the solution; carrying out a reaction for a period of time in an oxygen condition; taking out the silk fabric out and washingand drying the same; then transferring the silk fabric to a salt solution containing 10-100 mmol / L Fe<2+> and Fe<3+> to react for a period of time; taking out the silk fabric and washing the same andslowly drying the silk fabric at a low temperature; then drying the silk fabric at a high temperature to obtain the super-hydrophobic anti-ultraviolet flame-retardant silk fabric. The invention alsodiscloses the super-hydrophobic anti-ultraviolet flame-retardant silk fabric prepared by the preparation method. The preparation method is simple, environment-friendly and mild in reaction condition,and the super-hydrophobic anti-ultraviolet flame-retardant silk fabric prepared has stable super-hydrophobic, anti-ultraviolet and flame-retardant abilities in various environments.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a superhydrophobic anti-ultraviolet flame-retardant silk fabric and a preparation method thereof. Background technique [0002] The lotus leaf is an ideal superhydrophobic model in nature. It has a super-hydrophobic surface, its water contact angle is greater than 150° and its sliding angle is less than 10°, and it exhibits strong water resistance, self-cleaning, anti-sticking and anti-pollution functions. Superhydrophobic surface materials can be prepared by preparing micro- and nano-level structures and combining low surface energy substances. At present, there are many methods used to simulate the surface of lotus leaves, such as chemical vapor deposition, plasma etching, template processing, spraying process and dip coating method, but there are still many defects in these methods, such as complicated experimental process, practical and toxic Organic solvents, use of fluorinated rea...
