Cutting method of fabric material
View Patent ↗A fabric material has a base fabric, a pile layer on a surface of the base fabric, and an adhesive layer of a hot-melt adhesive on another surface of the base fabric. The adhesive layer contains a wax whose melting point Tm1 is from 20° C. to 50° C. lower than the melting point Tm2 of the base polymer. The fabric material is heated by a heating device to at least (Tm1+5)° C. and (Tm2−5)° C., and then cut by a ultrasonic wave cutter 23 . Thus the fabric material can be cut without generating the chaffs of the adhesive agent and the fiber offscums. As a result, the pollution is not made in the cutting process, and the cutting of the fabric material is made continuously and stably. Without the adhesion of the chaffs, the teremp which has a good surface formed by the cutting.
1. A cutting method of a fabric material having a surface coated with a hot-melt adhesive, wherein said hot-melt adhesive comprises a polymer and from 5 to 40 weight-% wax, and wherein a melting point Tm1 of said wax is from 20° C. to 50° C. lower than a melting point Tm2 of said polymer, said cutting method including steps of:
pre-heating said coated surface such that a temperature thereof is in the range of (Tm1+5)° C. to (Tm2−5)° C.; and then
cutting said fabric material while the temperature is controlled in the range of(Tm1+5)° C. to (Tm2−5)° C.,
wherein Tm1 is 70° C., Tm2 is 100° C., and the value for the expression (Tm1+5)° C. to (Tm2−5)° C. is 85° C.
