because the foot is wrapped in the shoe for a long time, the ventilation is poor, especially the sweat secretion increases sharply after exercise, the relative humidity in the shoe is as high as 80% ~ 90%, and the temperature is 35 ~ 40 ℃. Due to the lack of oxygen in the shoe, the temperature is appropriate, the sweat secretion is rich in fat and protein, the bacteria in the shoe easily proliferate at a high speed, and the dysbacteriosis of the foot skin causes malodor, 1n the long run, it can lead to a series of diseases such as tinea pedis and beriberi, which directly affect the foot health. After isolation and identification, there are 13 kinds of bacteria, 5 kinds of yeasts and 8 kinds of molds in most shoes. These pathogenic microorganisms will cause certain harm to feet. Therefore, in view of the new pathogenic bacteria identified in shoes, it is particularly important to carry out special antibacterial treatment on shoe materials. Therefore, kp-j150, a highly effective, low toxic and broad-spectrum antibacterial agent, is developed to effectively inhibit the growth of microorganisms in shoes. 1t not only cuts off the transmission path of bacteria, but also prevents the odor generated by its reproduction and decomposition of textile dirt< A kind of foamed insole and its preparation method: (1) mixing and stirring materials such as vinyl acetate, foaming agent and bridging agent in predetermined proportion(2) The foaming mixed material is rolled into a flat rubber plate(3) Using the cutting machine, the rubber plate is cut into several pieces of the primary embryo of the insole body with a quantitative reduced proportion(4) The primary embryo is directly covered in the forming die for heating, and the primary embryo is subjected to integral hot pressing in the forming die to expand the finished product in the first step of mixing, 0.5 ~ 1% antibacterial agent kp-j150 can be added, and other processes remain unchanged to prepare antibacterial insoles 3 antibacterial finishing process of insole fabric (a) suitable for setting finishing of knitted fabric flat width feeding – 1nfrared alignment – Two roll cross rolling mill – Pneumatic slack – Four roll weft finishing – Underfeeding – Mechanical weft setting – Expansion – Super feeding – 1nfrared edge detection – Three finger edge stripping, flat edge stripping – Brush wheel overfeed – Upper needle plate – Extended track – Setting in drying room; Spray cold air out of the drying room; Tension adjustment – (b) suitable for setting finishing of woven fabrics flat width feeding – 1nfrared alignment – Two roll cross rolling mill – Pneumatic slack – Photoelectric weft setting – Underfeeding – Super feeding – 1nfrared edge detection – Second finger edge stripping – Top clip – Setting in drying room; Spray cold air out of the drying room; Tension adjustment – Cold water roll cooling – Swing cloth add the antibacterial agent kp-mj150 into the setting solution, the amount is 15 ~ 20g / L, and the drying temperature is set at 150 ~ 170 ℃ 4 evaluation of antibacterial properties 1SO 16187-2013 test method for evaluation of antibacterial properties of footwear and footwear components DB35 / T 1048-2010 knitted spacer fabric for antibacterial shoes QB / T 2881-2013 technical conditions for antibacterial properties of footwear and footwear components Hg / T 3663-2014 test method for antibacterial properties of rubber shoes
