One of the major problems encountered by the end-customer in the textile industry is the lack of wet-fastness of dyes and printing on textiles. It is even more undesirable to see dyes and printings being removed during washing procedure in addition to the fact that the textile does not retain its original dyed color. In this regard, its common that textile manufacturers apply dyes fixing agents at the end of the process. They can also be used during the process of dyeing for environmental concerns (to reduce amounts of unfixed dyes in industrial waste water) and to improve the economic efficiency of the process linked to the amount of dye used. JAS manufactures high-performing cationic polymers under the UltraFix brand name to improve fastness of the dyes. In addition, we also offer anti-migration agents allowing a better uniformity of dying, a better color yield and brightness in the pigment dyeing processes.
During textile manufacturing, sizing of the warp yarn (appliance of a protective glaze) is essential to avoid breakage in the weaving machine. Acrylic polymers manufactured by JAS under the UltraSize brand are effective sizing polymers to be applied on fibers for a good protection of the wrap yarns. They improve flexibility and lubrication to all kind of yarns and are easily removed during de-sizing as they are completely water-soluble.
