What factors affect the rubbing fastness of fire retarant textile? What can we do?
2015-11-14 08:58  Clicks:
Rubbing fastness is one of the problem that how to improve textile quality. The main influential factors of textile rubbing fastness are related with surface friction, colored textile floating amount and the fastness of dye combined with fiber.
 
Influence factor
The rubbing fastness of textiles detection is divided into wet rubbing fastness and dry rubbing fastness. The former is to use dry white fabric rub colored textiles, the latter is use hydrous white fabric rub colored textiles. Under the action of friction, the wet rubbing fade of textile are caused by the floating color transfer of water-soluble dyes and colored fiber grain transfer, with exogenous process and abrasive water jet, the wet rubbing fastness is lower 1 grade than dry rubbing.
The rubbing fastness of textile depend on the floating color amount, the combination of dyes and fiber, dye penetration condition, the particles on the surface of the fabric. For example, the reactive dyes, dyes and fibers are fully integrated by covalent bond, the rubbing fastness will be high, as for the insoluble azo dye, if bad dyeing treatment, part of dye can not insolubilization, they only attached to the fiber surface mechanically, whihc will have lower rubbng fastness, floating color removal without a net, dye concentration is generally larger, which will reduce the rubbing fastness, in particular, the binding force of dyes and fibers is likely to be destroyed in the presence of moisture, so the wetrubbing fastness is lower than rubbing fastness.
 
Main countermeasures:
Choosing little quantity floating colorafter dyeing and good elevating power reactive dyes to remove floating color.
Make reasonable dyeing and finishing process to make sure dyes can combined with fivers fully, and fully penetrate inside the fiber to makes it not come to the surface of the fiber, after dyeing , it’s better to fully wash float color.
Good singeing, permeable agent and mercerizing, which are all beneficial to improvement the wet rubbing fastness.
Plus dedicated smoothing dye fixing crosslinker can fasten the dye and fiber combination, reducing the surface friction of textile, while makes the surface of the fiber form a dye-coated flexible membrane, so that the dye is not easy to peel off during friction, wet rubbingfastness generally increase from 0.5 to 1.0.
 
Epilogue:
Many factors affect the rubbing fastness of colored textiles, it should be taken from the dye selection, dyeing and finishing, reasonable use of special fixing agent to take action. In short, control colored textiles floating residues, reducing the surface of the friction coefficient, improve the combined fastness of dyes and fiber, they are all the most important measures.
