Polyurethane is an incredibly resilient, flexible, and durable manufactured material that can take the place of paint, cotton, rubber, metal, and wood in thousands of applications across all fields.
Polyurethane might be hard, like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber wheels, or sticky like glue.
Since its invention in the 40s, polyurethane has been used in everything from baby toys to airplane wings, and continues to be adapted for contemporary technology.
Nowadays we expect textiles to meet far higher standards. They have to be functional practical, easy care & attractive.The only way to meet these demands is by using modern finishing methods. These involve some degree of mechanical finishing, but processing chemicals also play a major role.

Water Oil Repellent Finish:Aquarepel XAN: Blocked polyisocynate. One of the main problems of water and oil-repellent finishing with FC derivatives is wash fastness. Wash fastness can be improved substantially by crosslinking the FC resins with Aquarepel XAN a fluoro carbon extender. Felt Free Wool Finishes:Dermaset BAP: An additive for felt free finishing of wool. The advantage of Dermaset-BAP is that it can be used on woven & knitted woollen fabrics without oxidative pretreatment(chlorination), so it is more environmentally friendly than alternative processes. This process has recently become important because applying this treatment after prescouring ensures problem free dyeing of woollen fabrics on jet units plus felt free finishing. This process makes it possible to use pure wool fabrics for machine washable trousers, shirts & skirts.

Crease Resist Finishes:Crease-resist finish that enhance dimensional stability are the most important finishes for cellulosic fibres. Cellulosic crosslinking agents, especially formaldehyde-based products, are used for this. There is the problem of free formaldehyde . Labeling and consumer protection organizations are enforcing with manufacturers to minimize the free formaldehyde content of textiles. The maximum limit for clothing worn next to skin are generally 75-300 ppm. The limits for children’s clothing are far lower. Low formaldehyde & formaldehyde free crosslinking agents require stronger catalyst because of their reduced reactivity. This catalyst tend to reduce the mechanical properties of cellulosic fibres. This is particularly critical in case of viscose.
Combining formaldehyde containing cross linker along with Permafin-UR gives following advantages:Finishes with low free formaldehyde content.High dry & wet crease recovery.Excellent self smoothening.Reduced loss in tenacity.Improved abrasion resistance & enhanced dimensional stability.
Hydrophilic Finish:
Permafin-UR as an absorbency & handle improver; suitable for polyester, cellulosic, woolen goods.
Improvement in pilling behavior & crock-fastness:
Permafin-UR can be used to produce a soft handle without increasing the fabric tendency to pill. The dry and wet crock-fastness of vat & sulphur dyeings can be improved by applying a finish of Permafin-UR.
