Problems solved by technology

[0010] Since antibacterial and antifungal are a concept involving a relatively wide range, the biological activities of different bacterial species are different, and the killing effects of different antibacterial agents on different bacterial species are also very different. Or the evaluation methods of antibacterial effect are also varied, and there is no strict comparability between the test results of various methods

Abstract

The invention relates to a preparation method for mildew-proof polyester cotton umbrella surface silks. The preparation method comprises the following steps of: performing dyeing and mildew-proof and waterproof finishing in the same bath on the pretreated umbrella surface silks; according to the process conditions, adding mildew-proof agent, disperse dye and sodium methylene dinaphthalene sulfonate, and regulating the pH value to 5; heating the mixture to the temperature of 60 DEG C, then heating the mixture to the temperature of between 110 and 130 DEG C, preserving the heat, cooling the mixture to the temperature of 40 DEG C, adding anhydrous sodium sulphate and active dye, heating the mixture to the temperature of 60 DEG C, preserving the heat, adding soda ash, preserving the heat, cooling the mixture to the temperature of 50 DEG C, draining and washing. According to the method, a one-bath two-step method is adopted in dyeing, namely the polyester fibers are dyed, and then the cotton is dyed by using the low-temperature active dye; the method has the advantages of short process route, dyeing and finishing in the same bath, energy conservation, emission reduction and low cost; and the umbrella surface silks have good color fastness and good antibacterial and mildew-proof effects.

Description

technical field [0001] The invention belongs to the technical field of polyester-cotton umbrella silk, in particular to a method for preparing mildew-proof polyester-cotton umbrella silk. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people are constantly pursuing new styles and functions of umbrellas, so some multifunctional and new style umbrellas are constantly being invented. Anti-mildew function umbrella silk is one of them. [0003] During the use of umbrella products, various external pollutions such as grease and human secretions will adhere to the fibers. In the case of humidity and heat, poor ventilation, etc., it is easy to cause the growth of microorganisms and produce low-level fatty acids (such as isovaleric acid, nonyl acid, etc.) acid, capric acid) and volatile compounds to emit stench, which affects the performance of umbrella products; at the same time, microorganisms are easy...
