Significantly Improve

M2 is a cationic waterborne polyurethane with active  group. The cation of the molecule can be combined  with the dye anion. Because there are a lot of O, H and  reactive groups on the molecular chain, O, H can form  hydrogen bonds with cotton fibers or dyes, and the  reactive groups can react with the hydroxyl groups on  cellulose at high temperatures, thus playing the role of  firmly "fixing" the dyes on the fibers.

Lasting and stable effect

This product uses a special end capping  technology. During the drying process, isocyanate  is released to form a covalent bond with the  hydroxyl group in cellulose molecules, and it also  has electrostatic bonding with cellulose molecules.  In the humid environment, the electrostatic effect  is weakened. Compared with the traditional fixing  agent that only rely on electrostatic binding, this  product can be firmly adhered on the fiber  surface by covalent action, serving as the "bridge"  between dyes and fibers, so that the  improvement effect is more stable and lasting.

Soft and smooth hand feel

The continuous network film formed between  polyurethane and fiber and dye is soft and  smooth, which does not affect the softness and  hand feel of the fabric, and improves the surface  abrasion resistance.The molecular weight of waterborne polyurethane  color fixing agent is large. It will bond and seal the  dye via resin film, completely cover the water-soluble groups of the dye, increase the smoothness  of the fabric surface, and reduce the friction  coefficient.

Breathable

The network film between polyurethane and dye and fiber has better air permeability and comfort than  traditional linear film.

No color variation, no pecul

Fixation will not cause color change to finished fabrics; No peculiar smell on the fabric surface after  fixing and drying.

Safe and sustainable

It does not contain APEO and formaldehyde and  complies with REACH regulations, ZDHC and  OEKO-TEX 100 standards.
