Problems solved by technology

The widely used durable finishing methods mainly include: chromium stearate complex; pyridinium quaternary ammonium salt; trimethylol melamine derivatives; silicone resin; It has common disadvantages: wear resistance, poor hand feeling, and does not have the function of oil resistance and anti-fouling (low temperature water repellency technology of real silk [J]. Silk, 1995, 5: 15-17.)
However, the use of fluorine-containing monomers to graft silk fabrics to achieve the purpose of water- and oil-repellent modification of silk has not yet been reported.

Abstract

The invention relates to a technique for modifying silk broadcloth functionally and discloses a water repellent and oil repellent finishing agent of the silk broadcloth, a preparation method and an application thereof. The finishing agent consists of an ethylene fluorine monomer, an emulsifying agent and water. The preparation method comprises the following steps that: the emulsifying agent is dissolved into water, the ethylene fluorine monomer is added drop by drop at a rotating speed of 11,000 to 12,000r/min to realize the emulsifying process so that the water repellent and oil repellent finishing agent of the silk broadcloth is obtained. A finishing solution is prepared according to the ratio that the ethylene fluorine monomer is 20 to 120 percent of the textile by weight, the grafting reaction is performed by taking potassium peroxydisulfate as an evocating agent, the soaping, washing by water and drying processes are performed to extract and to remove the autopolymer so that the silk broadcloth with the water repellent and oil repellent functions is obtained. The technique adopts the monomer direct grafting method, ensures that the modified silk fabric not only has perdurable water repellent and oil repellent properties but also has good tactile and strong ventilating property, greatly improves the service performance of the true silk, and widens the application of the real silk fabric to the textile and clothing industry.

Description

Technical field [0001] The invention relates to a functional modification technology of real silk, in particular to a water-repellent finishing agent on the surface of real silk, a preparation method and application thereof, and belongs to the technical fields of chemical industry and light textile. Background technique [0002] In recent years, the concept of traditional clothing function of silk is undergoing changes, especially its application fields have been continuously expanded. As outer clothing products, silk fabric has broken the conventional seasonal boundaries and is no longer mainly used as a thin summer clothing fabric. Water-repellent, oil-repellent and breathable silk fabrics are used in autumn and winter suits, ski shirts, shawls, high-end raincoats, interior decorations, etc. In addition, people have higher and higher requirements for real silk clothing, and even hope that it will not affect its wearing effect even in rain and fog. Therefore, the domestic and fo...
