The invention relates to a production process of 
flame retardant trim cow leather. The production process comprises the steps of fleshing, deliming, 
softening, tanning, shaving, retanning, 
dyeing, stuffing, 
drying, milling and finishing, wherein the step of tanning comprises the successive procedures of 
salting, 
pickling and chrome 
powder tanning; and the retanning, the 
dyeing, the stuffing, the low-temperature airing 
drying and the finishing adopt characteristic processes. The 
flame retardant trim cow leather is compact and uniform in body, is excellent in 
toughness, is good in resilience and is excellent in 
flame retardance, and the quality can be controlled easily in the production process; after the leather is stretched in a seat or is used, the seat can be kept in an optimal form and comfort because of excellent resilience of the leather; and under the 
precondition of guaranteeing the softness and flame retardance, the 
water resistance, the sweat resistance, the color fastness to 
rubbing and the 
wear resistance of a 
coating layer are effectively improved.
