[0020] The preparation method of this sofa leather with high wear resistance and flame retardancy mainly comprises the following steps:
[0021] 1) Wet coagulation coating: After the base fabric is pretreated, sizing and scraping coating on the coating machine, the sizing amount is 100~300g / m 2 , wet weight, knife distance 1.4~1.8mm, and then pass through the coagulation tank for solidification and molding, the concentration of dimethylformamide (DMF) in the coagulation tank is 8-25%, the temperature of the coagulation bath is 20-35°C, and the coagulation time is 5-15min; then enter Washing in the washing tank, the temperature of the washing tank is 20~90°C, and the DMF concentration in the last tank is 0~1%; after washing, it is dried and shaped, the drying temperature is 100~170°C, the time is 2~8min, and finally it is cooled and coiled, that is It is a semi-finished wet-laid bass; specifically: base fabric--pretreatment (brushing, pre-impregnation, calendering)--sizing and ...
