Conclusion Given the current dyeing fastness problems exist together, need to develop a series of non-formaldehyde fixing agent, in order to facilitate the formation of the dyeing process, to achieve high utilization of dyes, excellent fastness properties and achieve environment-friendly. Based on the existing strengths and weaknesses of fixing agent, as a good fixative trends: (1) direct good, high reactivity, good stability, application conditions are mild and strong fixation, general performance.
(2) low cost, low toxicity products, and even non-toxic, environmentally friendly applications.
(3) significantly improved dye fixation on the fiber, will not cause changes in shade.
(4) significantly improve the fabric wet fastness, rubbing fastness, improved dyeing properties, while both the finishing effect.
(5) does not affect the texture of the fabric, the fabric does not cause a decline in strength, does not affect the use of other additives. Source :google!
