With the continuous improvement of people's living standard, people wearing knitted with the new requirements: from a single warm-type functional shift gradually to the comfort, health, safety, aesthetics. In order to meet market demand, improve product quality, increase value-added products, knitwear and special finishing technology also will be developed. Currently, the special finishing of knitwear including anti-pilling, shrink-proof, anti-bacterial, refused water oil resistant, flame retardant, antistatic and health finishing. Winter cotton knitted underwear, it is directly next to the skin dressed in human skin appearance, when the dust bonded together in the secretion of human sweat, dander, grease and nature, easily formed in the contact area of ??the human body and clothing stains, grease spots, but also provide a breeding place for all kinds of bacteria. Fabric stain washed but it is difficult to be removed, If you repeatedly scrub, and cause underwear strength damage, therefore antimicrobial finishing and oil repellent water repellent, dirt repellent finishing is necessary. To meet the above two functional requirements, this subject experiments Shanghai Three Gun (Group) Co., Ltd. to provide the three warm knitted fabrics as a sample, using the \Function in the finishing process of the knitted fabric finishing agents used high-temperature baking finishing process will directly affect the wearability of the knitted fabric, This article experimental testing and analysis of knitted before and after the finishing of the different composite taking performance analysis of the the composite finishing process parameters affect the degree of taking performance knitted items. Antibacterial functional testing by professional testing organizations test article only self-cleaning function finishing the univariate analysis. Self the clean finishing agent JS-1 to finishing three warm knitted, finishing agent concentration, baking temperature and baking finishing effect greater impact, this article is based on three factors, and the area is divided into three arithmetic gradient, combined into a variety of finishing, performance test different finishing conditions of the knitted fabric. After finishing knitted fabric antibacterial, self-cleaning performance of qualitative analysis to determine that it has a good antibacterial, water repellent and oil, easy decontamination performance. The the impact factors finishing knitted wearability based on the three single factor analysis, comprehensive experimental data and other factors, drawn knitted antibacterial, self-cleaning multifunction finishing the better range of process parameters. Based on single factor experimental results to develop the the orthogonal analysis process further determine Jiaoyou to collate accurate values ??of the process parameters. Experimental results show that after finishing with the preferred whole process parameters warm knitted, not only has a good antibacterial, the self-cleaning function, and the items taking the minimum performance loss, wherein finishing confrontation gettering pilling, surface frictional properties substantially no effect, keep better feel; slight decrease in moisture permeability slightly improved breathability and warmth. In addition, the article also resistant to washing functional test sample after finishing and 5, respectively, according to the standard 10 times, 15 times of washing and measure its antibacterial, self-cleaning functionality. The experiment proved washed 15 times after the sample still effectively inhibit Staphylococcus aureus, has good antibacterial properties; With the increase in the washing cycles, water-repellent and oil contact angle declined slightly, but still maintain a good water repellent oil performance; easy decontamination performance by 5 before washing to 3, but still higher than the unstructured sample.
