Afterwards, such superposed weft yarns and non-woven layer assembly is subject to the high pressure jets of water from injectors disposed above the conveyor so that the weft yarns and the fibers or filaments of the non-woven layer are intermingled to obtain a base material of interlining. Then, the base material of interlining is dried in a thermal treatment. The dots of thermofusible polymer are deposited one face of the base material of interlining.Field of SearchBy applying after assembly an adhesive, solvent or chemical activating agentWith weaving, knitting, braiding, twisting or needling With axis of filamentary material nonparallel to axis of web Between plural webs By nonuniform adhesive application Running or continuous webs of indefinite length COATING REMAINS ADHESIVE OR IS INTENDED TO BE MADE ADHESIVE Heat sensitive adhesive By fluid jet needling or perforating Through backing and support members Including continuous filaments | |
