Hot melt adhesives for fabrics were prepared by doping with galactomannan in a certain proportion of 10%to 50%with polyamide hot-melt adhesive as the main body,whose properties were observed.The results show that galactomannan and polyamide hot-melt adhesive are successfully combined to form the hot melt adhesive for fabrics.The properties of the hot-melt adhesive are improved including tensile shear strength,peel strength,melt flow rate,low temperature flexibility,water air permeability and heat-resistant oxygen aging,while the softening point,Shore hardness and oxygen permeability are decreased.The tensile shear strength of the hot melt adhesive reaches the maximum of 5.7 MPa,the peel strength is 1.47 N/mm,the melt flow rate is 15.9 g/10 min,the softening point is 76.5℃when the mass fraction of galactomannan is 40%.
