Thermobonding interlining comprising a layer of fibers intermingled with

Abstract

A method producing a thermobonding interlining comprises the steps of depositing a non-woven layer of intermingled fibers or filaments presented in a general direction on a conveyor of wire netting, directing toward said conveyor weft yarns made of textured continuous filaments that are kept in a stretched condition and parallel with one another; depositing the weft yarns in a zone where the non-woven layer is being deposited such that the weft yarns are oriented crosswise to the general direction of and covered by the non-woven layer. 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.
