In textile products, the main factors that affect the color fastness to wet rubbing include the type of fabric and fabric structure; textile pre-treatment, such as desizing, scouring, bleaching, mercerization, etc.; the selection of textile dyes, as well as process, temperature, Whether the control of time, etc. is strict, and whether the selection and use of additives are correct; post-processing of textiles, etc. �<br /

Regarding these factors that affect the color fastness to wet rubbing, we should pay attention to the following points:<br /
<br /
1、 根据纺织材料学的分析，一般化纤类织物比棉等天然织物的耐湿摩擦色牢度要好，稀薄织物比厚重织物要好。所以在纺织物处理时，各道工序处理要匀透，以提高纤维的可吸性与染料的反应性或吸附固着性，使染料充分上染。在染色过程中，要求控制严格，对助剂等须正确选择正确使用。为提高纺织产品耐湿摩色牢度，在纺织物后处理中，可进行充分皂洗，如涤纶纤维用分散染料染色后高温定型导致染料泳移到纤维表面，引起摩擦牢度下降。针对这种情况，加固色剂或平滑剂可在一定程度上提高耐摩擦色牢度。
<br /
2、 选择染料时，选择具有良好提升性和匀染性的染料，良好的提升性和匀染性都有利于染料的渗透和扩散，可从一定程度上提高湿摩擦牢度。染料应具有一定的水溶性和直接性，水溶性基团不能太多，否则会影响后面的湿摩擦牢度。而直接性也应该选择以中等为佳。所选染料应具有的直接性不能太高，一般情况下应大于70%。
<br /
3、 棉等天然织物耐湿摩擦色牢度相对较差，因此对棉坯布而言应选择纱支均匀、布面光洁的坯布。若需要进行预处理应该选用高效前处理剂。
<br /
4、活性染料染色用水应尽量使用软水或去离子水，以此减少水中的钙镁等离子对染料的影响，从而提高纤维对染料的吸收性，使染料在纤维分子内固色更加稳定。
<br /
5. Use high-efficiency fixing agents. The selected fixing agent should be able to form a compound between the dye and the fiber. When reacting with the dye, it can also react and cross-link with the cellulose fiber, so that the dye and fiber can be tightly connected. The ground is connected together to strengthen the combination of dye and fiber, prevent the dye from falling off the fiber or migrating to the surface of the fiber, and avoiding the decrease in dye fastness. �<br /
<br /
6、 使用特种助剂，如增深剂等对染色织物进行整理，可减少染料用量而获得深浓色效应，同时提高湿摩擦色牢度。
<br /
7、 重视染后布面的ｐH值。因为一般情况下深浓色棉织物染色工艺用碱量较高，然后加强水洗、皂洗与中和，织物上不能带碱，以免染料染后水解，造成湿摩擦牢度下降。通常布面ｐH值控制在6.5—7.5，不能超过9或小于3。
<br /
8、 从改进染后布面的特点出发，对织物进行整理，如生物酶抛光处理等，使得布面光洁度增加，摩擦力变小，从而提高其湿摩擦色牢度。

9. The floating color on the fiber is extremely detrimental to the color fastness to wet rubbing. Fabrics dyed with deep and rich reactive dyes should be soaped twice. However, too many times of soaping will destroy the dyed dye, resulting in bond breaking. , leading to a decrease in effectiveness �曾有试验，将染色织物用防沾污洗涤剂洗涤（用量2－3ｇ/L，95℃处理10min），能使湿摩擦牢度达到3级� In actual large-scale production, many situations often occur, such as fluctuations in steam supply pressure, which prevents the temperature from rising high within the specified time; errors in vehicle operation or sudden equipment failure, causing deviations from the predetermined program; additional dyeing materials after color difference occurs; and Changes in process, etc., resulting in differences in color fastness (including cylinder differences) �对于某些机械设备和染料品种、碱剂等化学药剂，在大生产中要使染色后的清洗十分彻底不太实际，所以应合理地选择� �<br /
<br /
10. Since it is difficult to remove the floating color after dyeing with reactive dyes, appropriate color stripping agent can be used to remove the floating color after the soap is boiled, so that the fabric dye and fiber after removing the floating color can be removed. Form a complete body, thus improving its color fastness to wet rubbing �<br /

11. In view of the situation where the covalent bond formed between the reactive dye and the fiber may become unstable or even break under acid or alkali conditions, we can form a soft, strong, and water-resistant film on its surface to repel it. Water-based and soft smoothness to improve wet rubbing fastness Sol Gel method is an important method for preparing inorganic membranes. Films with different components are formed on fabrics through sol-gel technology, which can improve the wear resistance, water and oil repellency of fabrics, etc. Can improve wet rubbing fastness to a certain extent �但是，对其手感有一牢的影响� There are reports in the literature that YKA2955 and YKA2977 developed by Japan Yifangshe Grease Company can form a soft and strong film on the surface of the fabric when used as a 4:1 mixture for impregnation treatment of reactive dyes, thereby improving wet friction fastness. purpose of degree �
