Problems solved by technology

However, in the existing technology, the amount of chemicals used is large, some chemicals contain or potentially contain toxicity, and the production process is relatively cumbersome, and the reaction time is long. It is not suitable for large-scale production of functional silk that integrates color, anti-ultraviolet and hydrophobicity.
[0004] In addition, in the current dyeing technology of fabrics, the process is complicated, the energy consumption is high, and the production process also has certain harm to the environment, and the fastness, washing resistance and light fastness of the prepared dyed fabrics are still to be determined. improve

Abstract

The invention relates to a method for preparing a colored anti-ultraviolet hydrophobic fabric. The method comprises the following steps: soaking a fabric in a dopamine aqueous solution containing metal ions at 30 DEG C to 50 DEG C, wherein the fabric is a silk fabric or a wool fabric; rolling the fabric at a pressure of 0.1 kg / cm<2> to 1 kg / cm<2>, wherein the rolling over rate is 40% to 60%; treating the rolled fabric in an aqueous solution of an oxidizing agent at 40 DEG C to 60 DEG C for 20 minutes to 50 minutes; washing and drying the treated fabric at 60 DEG C to 90 DEG C, to obtain the colored anti-ultraviolet hydrophobic fabric. The colored anti-ultraviolet hydrophobic fabric and the preparation method thereof have the advantages that the raw material is environmentally friendly andeasy to obtain, the treatment temperature is low, the energy consumption is low, the production procedure is short, the efficiency is high, the industrial production is facilitated, and the product isintegrated with anti-ultraviolet effect and a hydrophobic effect.

Description

Technical field [0001] The invention relates to the technical field of textile finishing, in particular to a colored anti-ultraviolet hydrophobic fabric and a preparation method thereof. Background technique [0002] Known as the "fiber queen", real silk has a pearl-like soft luster, giving people a feeling of wealth and elegance, excellent moisture absorption and air permeability, and is widely used in high-end clothing fabrics and decorations. The wool fabric is also a common warm material. With the rapid development of my country's economy, the quality of life of the people has been greatly improved, and the requirement for textiles is no longer to keep cold and warm, but to be both beautiful and multi-functional. Colored anti-ultraviolet hydrophobic silk or wool fabrics can meet the requirements of such products. [0003] Patent CN 201710558475.6 discloses an anti-ultraviolet softening finishing agent for textiles and a preparation method. It uses methyl hydrogen-containing s...
