In recent years, with the rapid development of the national economy and living standards improve, people want to live in a cleaner environment comfortable. In daily life, we often encounter many unpleasant odors, such as sweat odor, body odor, cigarette smoke and smoke flavor and so on. Common odor main chemical ingredient is ammonia (urine and sweat, etc.), hydrogen sulphide (corruption eggs, etc.), trimethylamine (corrupt fish) and methyl mercaptan (corruption green onions) and so on. These not only taste unpleasant odor, but also may be hazardous to human physiology, to pose a threat to people's health. Textiles in close contact with the human body, the comfort of life plays an important role. Therefore, people want to wear clothing and bedding on the smell less, make more clean and comfortable surroundings. Industrial applications can be developed deodorants and finishing process, not only to a certain extent, improve air quality around and living environment, but also to enhance product quality and added value of having practical value and practical significance. β-cyclodextrin (β-CD) is a cyclic oligosaccharide, the molecule has a unique structure of a hydrophobic cavity, to the inclusion of ammonia, hydrogen sulfide, and many other guest molecules. Therefore, the subjects of such a β-CD inclusion ability to prepare a deodorant. While using β-CD deodorant deodorant finishing of wool fabric. In order to improve durability, were used two kinds of deodorant finishing process: β-CD Deodorant / aqueous polyurethane (binder method), and β-CD deodorant / polycarboxylic acid (grafting method). β-CD low solubility in water, access high solid content and dispersion properties of a good deodorant is the key to this project. First, the study cyclodextrin solubility in various solvents, based on the experimentally determined by comparing the mass of the β-CD percentage screened appropriate experimental apparatus and dispersion method of different cosolvent, different surfaces dispersion time of the active agent and deodorant performance, determined deodorant formulation and process of preparation, obtained with a high solids content and a high storage stability, stable performance diluted β-CD deodorant. Then, respectively, by means of an adhesive method (water-based polyurethane) and grafting (polycarboxylic acid), the use of β-CD deodorant deodorant carried out on wool fabric finishing, finishing fabrics washed by testing before and after ammonia absorption values Evaluation of β-CD deodorant deodorant in wool fabric finishing application performance. The experimental results show that after two methods after finishing of wool fabric significantly improved absorption of ammonia, deodorant effect. Wherein a polycarboxylic acid grafting finished fabric ammonia absorption values ??than the use of water-based polyurethane adhesive fabric finishing ammonia absorption value is slightly higher, indicating that the former deodorant finishing results slightly better than the latter. And 1,2,3,4 - butane tetracarboxylic acid (BTCA) as crosslinker finished fabric ammonia absorption value surpasses citric acid (CA) as the crosslinking agent of fabric finishing slightly higher, indicating BTCA with β-CD, and the crosslinking reaction of the wool fiber capacity than CA stronger. After finishing two ways sample after repeated washing after its absorption of ammonia value remains undigested samples 2-3 times, indicating that with good washing performance. The topics developed in β-CD-based deodorant finishing agents and finishing process, for the development of environmentally friendly functional textiles with good value and practical significance of theoretical guidance.
