The present application is a kind of low-temperature forming polyurethane resin and its leather product, the polyurethane resin, comprising the reaction product of polyisocyanate, polyol mixture and chain extender;Wherein, the polyol mixture contains polyester polyol, the polyester polyol includes mass ratio of 4:1~1:2 linear aliphatic polyester polyol and branched aliphatic polyester polyol. The low-temperature forming polyurethane resin prepared leather product can significantly improve the degree of phase separation of polyurethane internal soft and hard segment micro area, the resin as synthetic leather surface layer material, with polyurethane shoe sole can have good bonding strength at lower injection temperature, not easy to delaminate, and good heat aging resistance, low temperature resistance.

The utility model relates to the field of garment processing, in particular to a sportswear production waste treatment device. The sportswear production waste treatment device comprises a base, a conveying assembly, a recycling machine shell, a fixing plate, a driving motor and the like, the conveying assembly is installed on the upper portion of the base, the right side face of the base is communicated with the recycling machine shell, and the fixing plate is connected to the upper portion of the front side face of the recycling machine shell. And a driving motor is mounted on the fixed plate. The driving motor and the air blower are started, the driving motor drives the beating plate to beat clothes, fabric, waste velvet and buttons on the surface of the clothes are separated, the air blower operates to drive the waste velvet to the second collecting frame, the fabric falls into the upper portion in the first collecting frame, the buttons are screened by the screen and fall into the lower portion in the first collecting frame, and the fabric, the waste velvet and the buttons are separated. The operation is simple.
