Water based  polyurethane resin and dispersion can give the fabric excellent softness, plump, smooth feel, and has the advantages of washable, antistatic, high resilience, the traditional use of n-hydroxyl finishing agent, finishing the textile in the process of use will produce free formaldehyde.Formaldehyde-free finishing agent in the majority with diverse carboxylic acid type, high cost, after finishing on the fabric faults, such as fabric strength degradation in terms of fabric wrinkle resistant finishing, waterborne polyurethane resin, with its superior performance and environmental protection has been widely attention, used alone or with other resin compound with use, can improve the crease resistance of the treated fabric.

By adjusting the amount of water based polyurethane finishing agent, baking temperature and baking time, the whiteness, breaking strength and elastic recovery Angle of the fabric can be optimized.
Waterborne polyurethane retains some excellent properties of traditional solvent polyurethane, such as good wear resistance, flexibility, low temperature resistance and fatigue resistance, and has good adhesion to paper, wood, fiberboard, plastic film, metal, glass, leather and so on.
In addition, it also has some characteristics that the solvent type does not have.Water-based polyurethane is stable in water and can be miscible with water in any proportion.In the process of preparing waterborne polyurethane, the isocyanate group in the molecule has been used up, so there is no free isocyanate.The viscosity of waterborne polyurethane does not increase with the increase of molecular weight.
Waterborne polyurethane can also give the fabric soft and full hand and leather feeling, wear resistance, wrinkle resistance, elasticity, flexibility, moisture permeability and sewn.Adjust the structure of polyurethane polymer can also be used for fabric waterproof, oil-proof, anti-fouling, anti-pilling and other finishing.Therefore, it can be used as durable shaping finishing agent, anti-wrinkle and anti-shrinkage finishing agent, wear-resisting finishing agent, hand feeling modifying agent, imitation leather finishing agent, multi-purpose adhesive and so on.
