Sorption Behaviour of Acid Dyes by Soybean Protein/Poly （vinyl alcohol） Blend Fibre

The sorption behaviour of acid dyes by soybean protein/poly（vinyl alcohol） blend fibre was studied. The quantity of dye sorbed by the fibre increased markedly with the decrease in the pH of dyebath and reduced with the addition of neutral electrolyte when the pH was below 4.5, Acid dyes exhibited higher sorption rate constant and lower half dyeing time for the fibre than for spun silk and wool, which was related to the special morphological structure of the fibre, At pH 4, the sorption of disulphonated acid dyes with higher molecular weight followed the dual sorption mechanism of Langmuir plus Nernst-type partitioning well as they interacted with the fibre through electrostatic forces, hydrophobic forces and hydrogen bonds. It is considered that soybean protein and PVA components should be simultaneously dyed by disulphonated acid dyes with higher molecular weight.     

Comparison between the Direct Dyeing Kinetics of Bamboo and Conventional Viscose Fibers

Two direct dyes were applied to conventional viscose(CV)and bamboo viscose(BV)fibers,which were prepared from bamboo cellulose pulps,and the dyeing kinetics of two fibers were compared.Three kinetic equations,namely Chrastil,Cegarra-Puente,and Vickerstaff,were used to fit the experimental dyeing rate points,showing that the best result was obtained by the Chrastil equation.BV fibers displayed slightly higher dyeing rates and dye adsorption values at initial stages,but a bit lower dye adsorption values at eq...     

Synthesis of Aminolaurylpyridinium Chloride as Antimicrobial Agent

4-amino-laurylpyridinium chloride (ALPC) was synthesized and employed in antimicrobial finishing of wool fabrics. The structures of the salt was fully characterized by using FTIR, 1 H-NMR and 13 C-NMR analysis. The effects of pH conditions of finishing baths, finishing time and temperature, and salt concentrations were investigated. ALPC could form ionic interactions with anionic groups on wool, which contribute to durable antimicrobial functions. The finished wool fabrics exhibited antimicrobial efficacy against Escherichia coli. The washing durability of antimicrobial functions on the finished wool fabrics was also studied.     

Synthesis of New Type Antimicrobial agent CL and Its Application in Fabric Finish

Amino - functional silicone oil was used as a raw material to synthesize antimicrobial agent by means of alkyla-tion. Through synthetically judging every possible influential factor, a new method was developed to synthesize antimicrobial agent CL under moderate condition. Then, antimicrobial agent CL was emulsified with surfactants AEO - 9 and AEO - 3 in appropriate proportion. Practical properties of antimicrobial fabric were tested.     

Effects of Auxiliary Agents on the Dyeing of Polyester Super Microfiber

The influences of various auxiliary agents on solubility ofthe disperse dye were studied.In the presence of the auxiliary agents during the dyeing of polyester microfi-ber,the dye uptake and migration were measured andeffects of these agentes were discussed.The effect of mix-ture of these agents was also studied in an attempt to im-prove the levelling and depth of polyester super microfi-ber dyeing.

黏胶基蚕蛹蛋白纤维的漂白性能

黏胶基蚕蛹蛋白纤维成衣具有穿着舒适性、悬垂性优良的特点,但纤维呈黄色,影响其后续染整加工.研究了H2O2漂白条件对黏胶基蚕蛹蛋白纤维白度和纤维中蛋白质损失量的影响.结果表明:常规漂白工艺中选择碱性条件可以获得更高的白度,但纤维的氮元素损失最大;在漂白加工中采用硅酸钠作为稳定剂可以获得较高的白度;通过对纤维进行弱碱性条件下的阳离子化处理,使纤维中的蛋白质颗粒带正电荷,纤维在低的H2O2质量浓度条件下获得更高的白度,且纤维中的蛋白质损失得到很好控制.
