Abstract


Socks its natural and comfortable to wear, has been favored by consumers. But cotton socks in the wearing process and long-term in a sultry, hypoxia and wet conditions, the bacteria multiply rapidly in the metabolism of the sweat of long-chain fatty acids and the formation of the stench, so wear cotton socks easy given the unpleasant odor. The international community has long been the exact composition of the components of this odor no unified public opinion, the domestic no unified quantitative deodorant effect characterization methods. In this paper, the sol gel finishing cotton socks, cotton socks wearing by rubbing the release of negative ions in the shoes to create a relatively oxygen-rich environment, thereby inhibiting bacterial metabolism stench. The self-assembled anion test apparatus the different sol use amount of the rolling rate, curing temperature and curing time, and other process conditions obtained Mianwa anion emission testing, to filter the best finishing process conditions used in the sol-gel after finishing. Optimum finishing process as follows: the molar ratio of water and the silane coupling agent (n water: n KH-560) = 20:1 under the conditions of synthesis of the sol, the sol was diluted with distilled water at an amount of 20 g / L control Mianwa rolling I was 70%, pre-bake 20 min at 80 ℃, then by curing at 120 ℃ for 3 min. Thus, the optimum process sorted out socks anion release more than 1000 / cm3. Bacterial culture photo attached bacterial colonies after the finishing of cotton socks to wear after the finishing law than without finishing the same kind of socks. A deodorant effect characterization methods using GC-MS GC-MS, high performance liquid chromatography HPLC the Halimeter tone instrument ammonia detector tube acetate / iso Kyrgyzstan oxalic acid detection tube test odor gas component. The results show that: without finishing the one pairs 55g socks smelly gas component volatile sulfide content of less than 0.15 ppm ammonia gas content of 0.9ppm-10 ppm, acetate / iso Kyrgyzstan oxalic acid content of less than 1 ppm . In addition, the design method of of three characterization deodorant effect: the detector tube, silver nitrate discoloration assay and negative ion emission detection method. The results show that: the detector tube and discoloration of the silver nitrate detection method can be detected in socks to wear deodorant effects, but the detector tube to be different based on the detection of gas components to replace the detector tube, discoloration of the silver nitrate detection method applies only to white socks; anion release detection method can be predicted before the socks wearing deodorant effects characterization is more objective than the traditional sensory testing method does not give detected bring sensory discomfort; finishing this method this sol-gel with cotton socks The deodorant effect characterization of the law is most applicable.
