Organic halogens generated in the chlorlnatlon treatment of wool are proven to be acutely toxic to human beings. Legislation on environmental pollution has become more and more stringent in recent years. So the chlorlnation treatment is faced with disuse. Alkaline hydrolysis is adopted to reduce the AOX (Absorbable Organic Halogen) concentrations in the effluents from the chlorlnatlontreatment under 40℃ and pH values 9, 10, 11 and 12. After treatment the reduction of AOX appears approximately 65%.

The optimum technique for silk finishing with a silicone -containing epoxide A is as follows: The silk fabrics is twodipped - two - nipped in a finishing liquid with 6 % (w/w) of the silicone - containing epoxide A, and 0.3 % ofcatalyst with a pick- up of 100% ± 2%, then drying at60℃ for 3.5 min, finally steaming at 110℃ for 7 *** crease resistant finishing with the silicone-contain-ing epoxide A, silk can greatly improve both the dry andwet resiliencies. The finished fabrics can endure 20 timeshome laundry and still have good wrinkle resistant prop-erties, while other physical properties such as

The mathematical model of peripheral twist extent(PTE) length was set up by studying the kinematics anddynamics of the yarn in rotor groove. The value of PTElength was calculated by using numerical method, andthe factors affecting the PTE length were also *** results show that the theoretical predicted value ofPTE length seems to be consistent with the measured val-ue. The yarn linear density and rotor speed have re-markable effects on PTE length. The parameters includ-

Polypropylene superfine fibers or cell porous fibers were prepared from the bi-component blend fibers of polypropylene/easlly hydro-degraded polyester(PP/EHDPET)by alkaline hydrolysis process. EHDPET is a kind of copolyester that can be rapidly hydro-degraded in the hot alkaline solution. This paper discussed the kinetics of alkaline hydrolysis of EHDPET, and the effect of catalyst, bulk ratio and the content of polypropylene grafted maleic anhydride (PP-g-MAH) on the alkaline hydrolysis process. Meanwhile, the morphological change of the outer surface of blend fibers during this process was also investigated by the technology of scanning electron microscope (SEM).

An O / W emulsion non-solvent addition method was used to prepare ethyleellulose (EC) microcapsules of water soluble pharmaceutical (theophylline). The solvent and non-solvent reagents used in this work were toluene and cyclohexane. The effects of polymer concentration, core wall ratio and particle size on the kinetics as well as the dissolution rate of the drug were investigated. The results show that the dissolution rate increases with the increasing of polymer concentration and core wall ratio. The release of microcapsules prepared with different procedures can be selectively profiled with first order and Higuchi matrix kinetic models.

This paper centres on the mechanism of wastewater treatment technology for viscose fibre production, in-volving the removal of sulphide (S2-), zinc(Zn2+), and organic substances( CODer), and meanwhile, de-termines the optimal strategy for wastewater treatment of Shanghai No. 1 Chemical Fibre Factory. Hydrosul-phuric acid is a weak acid, and in a certain range of pH value(pH < 8 .18) the concentration of free S2- is below 1 mg/1. The H2S gas can be removed by intro-ducing compressed air. Actually, when pH < 3, the concentration of sulphide in wastewater can meet the discharge standard. As to zinc (Zn2+), owing to its amphiprotic nature, it can be precipitated completely while pH value is within 8.24-10.5 . With the com-bined method of oxidation and coagulation, the average removal of CODer reaches 81.37% , and the concentra-tion of CODer In the effluent is about 50mg/1 under the best conditions: both the concentrations of oxidant and coagulant are about 60 ppm and the pH is 7 .
