Abstract
A viscous printing paste is imprinted on a reverse surface of a foundation fabric of a surface-type fastener, and then the paste while being viscous is drawn by a suction force to penetrate the foundation fabric from the reverse surface to an obverse surface from which a multiplicity of interlocking elements project. Upon setting of the printing paste, a distinctive mark is produced on the obverse surface of the foundation fabric. With the foregoing processing steps, a large mark can be provided on the surface-type fastener without effecting negative influence on the shape and function of the interlocking elements.
Claims13
A method of providing a mark on an obverse side of a surface-type fastener including a multiplicity of interlocking elements on one of opposite surfaces of a foundation fabric, said method comprising the steps of:
- (a) imprinting a viscous printing paste on the other surface of the foundation fabric which is free of the interlocking elements, to produce a first printed mark thereon, the first printed mark thus produced having a reversed image of a mark to be ultimately provided;
- (b) forcing the imprinted printing paste while being still viscous to penetrate the foundation fabric from the element-free other surface to the one surface on which the interlocking elements are disposed, thereby producing a second printed mark on the element-carrying one surface of the foundation fabric;
- and
- (c) heating the printing paste to cure the same, thereby setting the configuration of the second mark.
