Research And Product Development Of Anti-bacterial And Anti-mite Multifunctional Household Textiles

With the enhancement of living standards, people pay more attention to their own health, so the functional household textiles win people's high favour. Functional household textiles refer to the household textiles with some special functions, such as security functions, intelligent functions, humanized functions, health functions, etc. The function performance of the functional household textiles is destined for the efficacy of health care, for example anti-bacterial products, deodorant products, anti-mite products and healthy sleep bedroom products, etc. To cause textile fabrics to have anti-bacterial and anti-mite functions become one of hotspots for the present functional new textile fabrics. To satisfy the request of the people for the functions of the textiles, the fabrics with anti-bacterial function, anti-mite function, excellent performance of vapor and liquid transportability and moisture permeability efficacy should be studied and developed. This kind of study can not only prevent diseases but also advocate healthy relaxed lifestyle. The significant of the researches is very important and the application prospect of the products is widest.Because of superior green environmental-friendly performance and special functional properties, the fabrics woven by the artificially anti-bacterial fibers have been attracted by the people. Two kinds of artificially anti-bacterial fibers were chosen and the lengthways and transverse sections were observed by SEM, e.g. anti-bacterial moisture absorption & perspiration elimination fibers and photocatalysed moisture absorption & perspiration elimination fibers. Then some basic performances were tested, for example the length, fineness, strength, tensility, moisture regain and so on. Meanwhile, strong stretch performance of the blended yarns included anti-bacterial moisture absorption & perspiration elimination fibers, photocatalysed moisture absorption & perspiration elimination fibers, tencel, hemp and bamboo fibers were tested and analysed. On this basis, ten kinds of sample fabrics were trial-produced by the blended yarns and the functional performances and wearability were tested and analyzed.Through making some researches on the anti-bacterial moisture absorption & perspiration elimination fibers and photocatalysed moisture absorption & perspiration elimination fibers, it could be found that there were some grooves and microporous structures on the surface of fibers which made the fibers had good capillary wicking effect. By testing the moisture regains, it also could be found that these two kinds of fibers had good moisture-absorption behavior and their moisture regains were both higher than cotton. Meanwhile composite antimicrobials particles and nano-tio2 grains on the surface of fibers made them had good anti-bacterial and anti-mite properties. The performance of anti-bacterial moisture absorption & perspiration elimination fibers and photocatalysed moisture absorption & perspiration elimination fibers both could satisfy the requirements of spinning. Thinking about the possibility of processing and comfortable requirements of subsequent product, it was a good technical way that blending these two kinds of multifunctional polyester fibers and other natural fibers.Through making research on the yarns which were blended by anti-bacterial moisture absorption & perspiration elimination fibers, photocatalysed moisture absorption & perspiration elimination fibers and natural fibers, it could be found that breaking strength and breaking tenacity of the blended yarns were gradually strengthened as the contents of chemical fibers increased and the contents of natural fibers decreased. And strength of these blending yarns could satisfy weaving requirements.Researches also showed that, in the error range, tight degrees and thickness of these ten kinds of samples were same and their properties were comparable. Then some performances were tested and analyzed, for example anti-bacterial test, anti-mites test, capillary effect test, moisture permeability test, air permeability test, crease recovery ability test, pilling resistance test, firm soft degrees test and drapability test. Test results showed that these ten kinds of fabrics had certain anti-bacterial, anti-mite properties and there was a linear relationship between these properties and the content of artificial anti-bacterial fibers. With the contents of anti-bacterial moisture absorption & perspiration elimination fibers, photocatalysed moisture absorption & perspiration elimination fibers increasing, they would be improved. During the fabric development, we could add different proportions of moisture absorption & perspiration elimination fibers and tencel to improve the wettability of fabrics, add different proportions of moisture absorption & perspiration elimination fibers and hemp fibers to improve the permeability of the fabrics, change the structure of blended yarns to improve the wrinkles resistance performance of the fabrics, add tencel to improve the pillingresistance of the fabrics, add hemp fibers to improve the stiffness of the fabrics, add bamboo fibers and tencel to improve the drapability of the fabrics.Because the functional and wearability performances of these ten kinds of fabrics each was different, the method of fuzzy comprehensive evaluation was used to arrange comprehensive performances of the fabrics, then according to the actual market demands, an excellent-performance fabric was selected as the basis to develope a group of "Chinese wind" bedding packages, they could be well integrated into Chinese style of indoor decoration and there would be good prospects in the market.
