章探讨了pH值、温度对羊毛织物用M型活性染料染色的影响及壳聚糖脱乙酰度、浓度及分子量等对经壳聚糖处理后的羊毛织物染色性能的影响。结果表明,经壳聚糖处理后的丰毛织物用M型活性染料染色,能获得较高的固色率和K/S值。提高处理液中壳聚糖的脱乙酰度或浓度都能提高活性染料对手毛织物的固色率和K/S值,而义对染色样的温处理牢度和摩擦牢度影响不大。壳聚糖的分子量对织物的染色性能无明显影响。 相似文献

羊毛经阴离子型活性变性剂处理后,纤维侧基上被引入阴离子型基因,具有和腈纶纤维类似的结构。因而,变性羊毛能够用阳离子染料染色。增大变性剂的分子量、共轭双键数及相对疏水性,变性羊毛用阳离子染料染色时上染速率和上染率均可显著地增大,染色牢度也大为改善,但对酸性染料产生防染作用。从变性羊毛的红外吸收光谱图上可看到,在波数为1150~1260cm-1、1010~1080cm-1和600—700cm-1处均出现磺酸基的特征吸收峰。变性剂和羊毛间形成共价结合成为纤维侧基的一部分。变性羊毛表面的电性能有较大变化,但其物理机械性能如减溶解度、弹性、断裂强度等基本不受影响。 相似文献

低温氧等离子体处理对羊毛织物性能的影响 总被引:1,自引:0,他引:1
为了改善羊毛织物的毡缩、润湿等性能,采用低温氧等离子体对羊毛织物进行改性处理.通过单因素实验,综合评价羊毛织物处理前后的性能变化情况,分析了羊毛织物性能变化与等离子体处理时间、功率和压强变化之间的相互关系;利用原子力显微镜表征了处理前后羊毛纤维鳞片结构的变化情况.实验结果表明,利用低温氧等离子体对羊毛织物进行改性处理,可以获得较好的防毡缩效果,并能改善织物的润湿性能.有效控制处理条件,织物的断裂强力和伸长率不但不会减小,反而可以得到一定程度的增强. 相似文献

One-bath Dyeing of Polyester/Wool Blend with Disperse Dyes 总被引:1,自引:0,他引:1
The role of auxiliary LAB as vehicle in dyeing polyester/ wool blends with disperse dyes is described. Dye exhaustion and bonding on polyester/wool samples are studied under different experimental conditions - the LAB amount, the temperature and pH value - to achieve optimum conditions. The results are compared with those obtained with and without conventional dyeing auxiliary products. Although dye exhaustion is higher in the presence of commercial carriers, the dye bonded increases markedly in the presence of auxiliary LAB in both fibers. The role played by auxiliary LAB in polyester/wool blend dyeing can provide a new method for this process. 相似文献

Wool tops was modified by low temperature glow discharge (LTGD). The inputted power, the treating time and the pressure or vacuum were found to play an important role. The wool tops were dyed with reactive dye under a constant dyeing temperature after plasma treatment. Then the dyeing behaviors were studied based on the data of uptake, fixation, dyeing rate and fixing rate. The results revealed the possibility of low temperature dyeing and the suitable parameter of LTGD treatment. 相似文献

The dyeing and finishing properties of wool treated with chitosan were studied. It was shown that chitosan can be absorbed by wool in an acetic acid bath, both dyeing rate and equilibrium dye uptake of wool treated with chitosan increase in a wide pH range from strong acid to neutral conditions. This work also indicated that chitosan could be used to achieve feltproofing of wool. 相似文献

The central composition experimental design of multiva-riate Response Surface Method was used to formulate mathematical models aiming to predict (1) the optimum dyeing conditions of simulated waste Tikuanyin tea for wool fabric and (2) the optimum extraction conditions of a natural mordant originated from common waste eggshell. The pre - mordanting eggshell was applied to wool fabric before dyeing with simulated waste Tikuanyin tea under the optimum dyeing conditions. After mordanting the wool fabric with extracted natural eggshell solution, the prominent effect of increment in dye uptake and improvement of the properties of light fastness, washing fastness and rubbing fastness were evaluated. 相似文献

Shrinkage Properties of Wool and Acrylic/Wool Plain Knitted Fabrics Treated with DC109 总被引:1,自引:0,他引:1
This paper examines the effects of shrink - resist treatment, washing cycle and fabric tightness on the shrinkage properties of plain knitted fabrics made from 100% wool, acrylic/wool (50/50) and acrylic/wool (70/30). It was found that shrinkages of both treated and untreated wool fabrics were negatively correlated to fabric tightness and exceeded the IWS shrinkage limits (5% in length and 8 % in area) after 2 - 5A washing cycle. The effect of tightness was not as obvious with acrylic/wool (A/W) fabrics, but the shrinkage was seen to increase with stages of washing cycle for untreated A/W fabrics with some exceeding IWS standard. By applying the DC 109 shrink - resist solvent treatment, it was identified that by with higher percentage of acrylic fibre blended with wool, shrinkage could be reduced considerably and within acceptable limits. 相似文献
