Description
Technical Field
The invention relates to polyurethane superfine fiber base cloth and a preparation method thereof.
Background
In recent years, with the increasing importance of the country on environmental protection, more strict environmental protection policies are issued, enterprises are forced to increase environmental protection facilities, and new processes and new equipment are adopted to save energy and reduce emission.
In the past, solvent systems such as DMF/TOL, DMF/MEK and the like are used for dry-process veneering, although the DMF recovery technology is mature, the recovery technology of mixed solvents is difficult, the cost is high, and low-boiling-point solvents such as TOL, MEK and the like cannot be recovered, so that pure DMF is used as a solvent carrier to replace the conventional mixed solvent systems such as DMF/TOL, DMF/MEK and the like, the VOC emission is reduced, the temperature of a veneering oven needs to be increased due to the high boiling point of DMF, and the veneering release paper is curled due to the large heat shrinkage of base cloth, so that low-heat-shrinkage base cloth is needed in the market. The organic silicon resin is used for veneering, no solvent is used in the production process, and the method is environment-friendly, but the veneering processing also needs high temperature, and low-shrinkage base cloth is also needed.
The conventional superfine fiber base cloth is placed in a constant-temperature oven at 140 ℃ for 10 minutes according to the industry and customer test heat shrinkage method, and the shrinkage rate is tested. The heat shrinkage requirement of the shoe leather base cloth is less than 3 percent, and the requirement of part of customers is less than 2.5 percent; the thermal shrinkage requirement of the sofa leather base cloth is less than 4 percent.
In order to meet the requirement of thermal shrinkage, the spreading and setting temperature is adjusted to 170-: firstly, special high-temperature resistant resin needs to be selected; second, if the oven fails, the base fabric stays in the oven, causing serious damage to the base fabric. Some people adopt the base cloth to knead the skin and then pre-bake once, the thermal shrinkage value can be reduced, but the cloth drying cost of 0.5 yuan/m can be increased, and the thermal shrinkage value is between 1.0 and 2.5 percent, so that the high-temperature processing requirements of customers can not be completely met.
