ABSTRACT OF THE DISCLOSURE A novel, self-lined fabric is produced on a stitch- through type machine using the apparatus and method of the in- vention in which a plurality of optional warp yarn textile ele- ments are laid on a flexible interstratum (e.g., a layer of textile filling elements) which in turn is laid on a flexible lining or backing material (e.g., a non-woven fabric or acrylic foam- coated non-woven fabric) such that the interstratum is disposed between the lining material and the warp yarn elements. The warp yarn elements, interstratum and lining material are joined together by means of knitting thread which is stitched through the fabric components and forms a multiplicity of warpwise loop chains (e.g., a chain stitch or, when warp yarn elements are present, a half-tricot stitch) with the chains of loops formed on the rear surface of the fabric to secure the warp yarn elements interstratum and lining material against relative displacement and to form thereby an integrated, unitary, self-lined fabric structure. The apparatus for producing the self-lined fabric on a stitch-through type machine comprises, in combination means for supplying lining material, means for withdrawing the material from the supply means, and means for guiding the withdrawn lining material to the work zone of the machine independently of the interstratum and warp yarn elements. In the present method of producing the self-lined fabric, the lining material is delivered to the work zone of the machine conjointly with and independently of the interstratum and warp yarn elements such that the inter- stratum is disposed between the lining material and warp yarn elements and secured thereto by the knitting thread. -1-
