抗皱纤维素膜的制备与性能研究

利用氢氧化钠-尿素-硫脲溶剂体系将纤维素浆粕溶解,向溶液中添加1,2,3,4-丁烷四羧酸,配制成纤维素纺丝液并制得了纤维素膜.通过红外光谱分析和折皱回复角、断裂强力等测试,表征了膜的结构和性能.结果表明,该纤维素膜在一定条件下可以发生酯化交联反应并具有抗皱性能.改变1,2,3,4-丁烷四羧酸的用量、反应温度和反应时间,可以在纤维素膜的折皱回复角和断裂强力之间取得某种平衡.     

海藻酸衍生物与柠檬酸混合应用棉织物抗皱整理工艺研究

将海藻酸衍生物PGA与柠檬酸混合用于棉织物的抗皱整理,改变PGA、柠檬酸的用量、不同的焙烘温度及焙烘时间,通过测试整理后织物的折皱回复角、白度以及撕破强力等性能确定最佳工艺。结果表明较优工艺条件为:海藻酸丙二醇酯为25g/L,柠檬酸为60g/L,焙烘温度为170℃,焙烘时间150s。     

Application Performance of a New Antibacterial Flame Retardant for Cotton Fabrics

An excellent and novel flame retardant and antimicrobial agent, monochlorotriazine triethylphosphite guaridine(MCTPG), which made in the laboratory could treat cotton fabrics and dyeing with reactive dyes at the same time. The dyeing and functional property of treated cotton fabrics is characterized by five variables, each with a different effect on the final product. The best dyeing and flame retardant finishing process of reactive red K and MCTPG:2%(owf)reactive red K, 250 g/L MCTPG, 40 g/L NaCl, and 60 g/L Na_2CO_3, the fixation temperature is 90 ℃, and the fixation time is controlled at 60 min, with a bath ratio of 1:30. The percentage of dye uptake rate can reach 61.9% and the fixation rate is 52.8%. The treated cotton fabric has better flame retardancy and antibacterial property. The limited oxygen index(LOI) reached 26.3%, the after-flame time was 7.1 s, the char length was 65 mm, and the width of the bacteriostatic band of Escherichia coli and Staphylococcus aureus both reached 2.0 mm.     

Wrinkle Resistant Finishing of Cotton Fabrics with the Complex System of PBTCA/CA

In this paper,the wrinkle resistant finishing of cotton fabric with the complex system of PBTCA and CA was mainly discussed.The influence of finishing conditions such as the amount of finishing agent and catalyst,curing temperature and curing time were studied.Wrinkle recovery angle(WRA),breaking strength(BS) and whiteness(Wh) of finished fabric were measured.The experimental data indicated that the best finishing conditions were PBTCA 120g/L,CA 50g/L,sodium hypophosphite 50g/L,triethanolamine 20g/L,cured 170℃ for 120s.
