熔融纺丝成形条件对PET初生丝超分子结构及其力学性能的影响：第2报 单…

本文考察了单丝线密度、侧吹风速度以及喷丝头拉伸比对ＲＥＴ初生丝结晶作用及力学强度的影响。表明ＰＥＴ初生丝的结晶作用对单丝线密度的变化极为敏感。当单丝纤度减少时，初生丝的结晶度、侧向晶粒尺寸均大幅度增加、且最大结晶度出现的位置移向低纺速区。增大喷丝头拉伸比的作用有点类似于减少单丝线密度。但当喷丝头拉伸比超过一定值之后，结晶度虽仍在增加，而侧向晶粒尺寸却似乎已达饱和值。强化冷却条件，即加大侧吹风速，虽

A kinetic and thermodynamic study of lac dye adsorption on silk yarn coated with microcrystalline chitosan

The coating of silk yarn with microcrystalline chitosan (MCCh) was carried out using the ultrasonic‐assisted method at a pulsed wave frequency of 80 kHz, which only had a slight impact on the yarn as measured by changes in Young's modulus and percentage of elongation compared with untreated silk. A significant enhancement of lac dye uptake onto MCCh‐coated silk yarn compared with the untreated silk was observed. The rate of dye uptake at different temperatures onto silk yarn coated with MCCh was investigated. It was found that the adsorption rate constant and diffusion coefficient both increased with increasing temperature, as a result of a diffusion kinetically controlled process with a diffusion activation energy of 9.40 kJ mol^?1. This suggests that dye adsorption on silk yarn coated with MCCh is a physisorption process. The free energy change (?G^○), enthalpy change (?H^○) and entropy change for dye adsorption were also determined, and the negative values of ?G^○ and ?H^○ obtained indicated that the lac dye adsorption process is both spontaneous and exothermic.     

Synthesis and Characterization of AgBr–Silk Nanocomposite Under Ultrasound Irradiation

The growth of silver bromide nanoparticles on silk yarn was achieved by sequential dipping in alternating bath of potassium bromide and silver nitrate under ultrasound irradiation. The effect of concentration, power of ultrasound irradiation and the numerous of sequential dipping steps in growth of the AgBr nanoparticles on silk yarn were studied. The samples were characterized with powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and Inductive Coupled Plasma (ICP). The lower average size and the higher crowded AgBr nanoparticles upon silk yarn are the result of using ultrasound irradiation.     

SBS三嵌段共聚物及聚氨酯对涤纶纱线拉伸性能的影响

为进一步研究涤纶纱线的拉伸性能,将聚氨酯及用苯乙烯溶解的苯乙烯-丁二烯-苯乙烯三嵌段共聚物(SBS)对涤纶进行不同工艺处理,并进行拉伸性能测试和结果分析。结果表明:随整理液质量分数的增加,处理后纱线的断裂强力、断裂伸长率、断裂功均呈现先增后减趋势,但断裂强度较原纱均有所降低,而且聚氨酯整理后纱线的断裂强度较SBS整理的下降程度更大。对于纱线断裂强力、伸长率及断裂功的提高,聚氨酯整理效果优于SBS,而对于断裂比功,SBS的整理效果优于聚氨酯。

The preparation and processing of tussah silk

Tussah silk is well known for its fast fawn colour, which is often preserved in the manufacture of dress and other fabrics. Hence the processing of tussah for fabrics has not been very common, except for certain ladies' apparel such as sarees, scarves, etc. Little information on the practical processing of tussah silk has appeared in the technical literature. The present paper will attempt to review the preparation, dyeing, printing and finishing of tussah silk based on laboratory and mill experience.
