Determination of Crosslinking Degree of Polycarboxylic Acid with Dyeing Method 染色法测多元羧酸的交联程度
In pace with the raising of setting temperature, the crystallinity, degree of orientation and size of crystal grain will be increased, dye uptake rised, but the dyeing evenness declined. 聚酯细旦丝随着定形温度的增加,结晶度、取向度和晶粒尺寸增加,上染率提高,同时匀染性降低。
There is a great difference in the deformed degree of dyeing veneers, smooth level has a relation with wood density. 染色单板的变形程度有较大差异,平整度与木材密度相关;
Four factors to dye, the influence degree in order is dyeing temperature, concentration of NaCl, dye solution concentration and dyeing time. 四个作用因素对染色效果的影响程度依次为染色温度、NaCl浓度、染液浓度、染色时间。
It is important to screen the disperse dyes which is used on ultra-fine fiber to raise chrominance and reach the degree of even dyeing. 如何选择超细纤维用分散染料,以提高织物的色浓度,并在短时间内达到匀染效果,是保证织物染整效果的重要环节。
Abstract The effects of concentration of available chlorine in sodium hypochlorite solution, the treatment time and pH value on the degree of chlorination of polypropylene fabric were studied in this paper. The optimum technology of chlorinating and Dyeing were obtained. 本文探讨了次氯酸钠有效氯浓度、氯化pH值及氯化时间对远红外丙纶织物氯化改性的影响,研究了丙纶氯化及氯化丙纶织物染色的工艺条件。
The experiments showed that the addition of PVP to stain-proofing agents resulted in some degree of anti-staining effect on the white background of the printed fabrics, and PVP could remove effectively the loose color in the reactive dyeing to increase the soaping effect in reactive dyeing. 实验结果表明,添加PVP配制的防沾色剂对防止印花织物白地沾污具有一定的效果;PVP能有效去除活性染料染色后的浮色染料,提高活性染料染色后的皂洗效果。
Higher degree of refining was good for dyeing. 打浆度高的浆料有利于染色。
The suitable concentration of chitosan is in the rage of 0.2%~ 0.4%. The degree of dyeing has increased reaching 16 times. 适宜的壳聚糖浓度在0.2%~0.4%范围内,上染率均有提高,最高可提高16倍。
