SZ蛋白酶对羊毛的减量和防毡缩性能的影响

在用蛋白酶对羊毛织物进行改性处理的研究中，获得一种对羊毛具有独特处理效果的蛋白酶ＳＺ。本文主要就ＳＺ蛋白酶对羊毛的减量特性及其防毡性能的影响进行研究。ＳＺ蛋白酶采用Ｐｅｒｚｙｍ工艺对羊毛进行减量处理，可有效地防止羊毛毡缩。减量处理对羊毛的损伤较小，实际应用可以被接受。研究表明，羊毛的减量防毡缩处理并不需要完全去除鳞片，对于有效的减量，去除２／３的鳞片可获得最佳的减量处理效果。     

Wool powders used as sorbents to remove Co ions from aqueous solution

The Co²⁺ sorption of two wool powders was investigated using its radioisotope ⁵⁷Co (T_1/2 = 271.8 days and γ = 122.1 and 136.5 keV) as a tracer. The effects of the type of buffer, the pH value, the contact time and the initial concentration of Co²⁺ on the sorption behaviour of wool powders were studied. The Co²⁺ releasing ability of wool powders and the re-use of wool powders to sorb Co²⁺ were also examined. The optimum sorption of Co²⁺ by the powders occurred at pH 8 in phosphate buffer and pH 10 in ammonium sulphate buffer. Fourier-transform infrared spectroscopy (FTIR) was used to study the changes in chemical structure of the wool after exposure to both buffer solutions. Compared to the untreated wool fibre, the fine wool powders showed rapid sorption rates and high sorption capacities for Co²⁺. Co²⁺ ions were recovered after exposing the Co²⁺ loaded wool to HCl (0.1 M) and buffer at pH 3 (glycine/sodium chloride). After releasing Co²⁺ ions from wool powders, the efficiency of wool powders re-used to sorb Co²⁺ was 80% of that of the fresh wool powders. It is concluded from this study that wool powder can be used as an efficient sorbent to remove and release Co²⁺ from solution.     

羊毛和羊驼毛纤维弯曲性能的评价

单纤维弯曲性能的评价是研究纤维自身弯曲性质和纺织品柔软性能的重要方面.文章采用纤维轴向压缩弯曲法测量了单纤维弯曲性能.结果表明,羊驼毛比羊毛有更高的抗弯性能,即较刚硬,但羊驼毛纤维表面摩擦阻力较低,即纤维间易于滑移,因此羊驼毛织物手感柔软的主要原因是纤维间的滑移.

Conductive wool yarns by continuous vapour phase polymerization of pyrrole

Conducting polypyrrole (PPy) coated wool yarns were prepared by a continuous vapour polymerization technique, using a speed of 1 m/min with different iron(III) chloride (FeCl₃) as the oxidant at different concentrations. The resistivities, tensile properties, longitudinal and cross-sectional views of PPy-coated wool yarns were investigated. Optimum specific electrical resistances of 2.96 Ω g/cm² at 80 g/L FeCl₃ and 1.69 Ω g/cm² at 70 g/L FeCl₃ were obtained for 500 and 400 twist per meter (TPM) yarns, respectively. PPy-coated wool yarns exhibited higher elongation than uncoated yarns. Longitudinal and cross-sectional views of the yarns indicate that PPy coating penetrated deep into the yarn cross-section and a uniform coating was obtained on the surface of the yarn surface.
