Abstract

In the invention, we modify the conventional polyurethane to form a polyurethane which are capable of covalent dyeing with the dye molecule, therefore, it has a heavy color, anti-migration and better light-fastness. In this invention, we introduce the HEDA(N-(20hydroxyethy) ethylene diamine) into the conventional polyurethane to form a secondary alcohol and then sye with the epichlorohydrin (EpCl) modified disperse dye or the reactive dye, to form a covalent dyeing of dye molecule. The process is to add the HEDA (N-(2-hydroxyethyl) ethylene diamine) during the synthesis of polyurethane resin, therefore the secondary alcohol in the polyurethane can react with the epichlorohydrin modified chlorine-terminated disperse dye or the reactive dye to form a covalent bond between the polyurthane and the dye molecule.

Description of the invention (1) PU artificial leather is generally made by coating a PU resin solution on a non-woven fabric to form the surface layer. In terms of aesthetics, the coloring method is to mix the pigment with the PU resin solution and apply the coating. The color is relatively dark, lacks vividness, and the pigment is liable to generate migration due to heat. As for the dyeing of PY elastic yarns, disperse dyes or acid dyes are generally used. Dyeing for a long time (50 ~ 60 min ·) under high temperature (9G ~ 1G0 ° C) high pressure is a waste of time and energy, and the hardness of PU The crystals in the hard segment area will be damaged, resulting in poor physical properties. On the other hand, although this dyeing method is easy to dye, it is also easy to fade, and it has the problem of color difference. To avoid the lack of PU dyeing, the "synthesis of polyurethane polymer that can bind dyes" in this case can be covalently bonded in a dyeing manner. The dye is grafted onto the PU molecular chain, which will bring the PU to the belt after polymerization. It is colored, or the PU colorless polymer synthesized by this method can be coated on woven or non-woven fabrics, or spun into solution to form elastic fibers, and then covalently combined with dyes for dyeing. In the present invention, N- (2-hydroxyethyl) ethylene-diamine (HEDA) (N- (2-Hydroxyethyl) Ethylene diamine) is added to the synthetic polyurethane to make it have a secondary alcohol in the molecular chain. It is characterized by reacting with chlorine-containing disperse dyes or reactive dyes modified with epichlorohydrin (Epi-chi orohydri II) to form a covalent bond between polyurethane and dye.
