Patent number: 5924179Abstract: A method of the invention relates to treating a textile base material for thermobonding interlining, the material being constituted by a woven fabric or a weft knit that includes texturized synthetic threads, in particular air jet texturized threads, which form loops on a top face that is to receive spots of glue, and on an opposite, bottom face. The method consists in subjecting said textile base material, prior to applying spots of glue thereto, to emerizing or equivalent pre-treatment on its bottom face and to pre-treatment on its top face for reducing the height of the loops, e.g. singeing or heat treatment by radiation or by contact. Preferably, the textile base material is initially subjected to emerizing or equivalent pre-treatment on its bottom face, and subsequently to singeing pre-treatment on its top face.Type: GrantFiled: May 21, 1997Date of Patent: July 20, 1999Assignee: Lainiere de Picardie S.A.Inventor: Pierrot Groshens

Patent number: 5688558Abstract: The textile support for thermo-bonding interlining according to the invention is constituted by a weft knit, composed exclusively of yarns of biodegradable cellulosic matter, particularly viscose, the warp being exclusively of continuous multi-filament yarns.The support was preferably subjected, prior to the application of the thermo-fusible polymer spots, to a treatment of mechanical compacting by passage between a heated cylinder and a compression belt, the temperature of the cylinder being at the most 130.degree. C.The thermo-bonding interlining, comprising the textile support mentioned above, after application of the spots of thermo-fusible polymer, was advantageously subjected to a second treatment of mechanical compacting, similar to the first, the cylinder being heated only to a temperature less than 80.degree. C.Type: GrantFiled: March 28, 1996Date of Patent: November 18, 1997Assignee: Lainiere de Picardie S.A.Inventor: Pierre Groshens

Patent number: 5593533Abstract: 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.Type: GrantFiled: June 1, 1995Date of Patent: January 14, 1997Assignee: Lainiere de Picardie S.A.Inventor: Pierre Groshens

Patent number: 5534330Abstract: The thermobonding interlining comprises at least one non-woven layer of intermingled fibers of filaments presented generally is a longitudinal direction. One face of the non-woven layer is coated with dots of thermofusible polymer. It further comprises weft yarns which are textured continuous filaments. The weft yarns are disposed crosswise to the longitudinal direction and bonded to the non-woven layer due to the intermingling of the fibers or filaments of the non-woven layer. The dots of thermofusible polymer are disposed on the face of the non-woven layer on which the weft yarns are partly exposed. The interlining can also comprise two non-woven layers of intermingled fibers or filament between which the weft yarns are sandwiched. The dots of polymer are coated on one of the non-woven layers. The number of dots is equal to or higher than 60 per cm.sup.2.Type: GrantFiled: October 4, 1994Date of Patent: July 9, 1996Assignee: Lainiere de Picardie S.A.Inventor: Pierre Groshens

Patent number: 5286548Abstract: The thermobonding interlining is a nonwoven covered on one face with dots of thermobonding resin. According to the invention, the nonwoven is a web, containing no binding agent, of which the g/m2 weight is less than 50, which is produced from fibers in a thermoplastic material, such as polyamide; the mean diameter of the fibers is comprised between 1 and 5 .mu.m, the consolidation of the nonwoven is obtained by intermingling of the fibers by high pressure streams of fluid, notably by injection of water at pressures of 40 to 80 bars, or by thermal bonding. For example, the fibers being obtained from a mixture of constitutents having different melting points, the bonding points result from the melting and bonding of the zones of fibers having the lowest melting point.Type: GrantFiled: July 3, 1991Date of Patent: February 15, 1994Assignee: Lainiere de Picardie (S.A.)Inventors: Robert Bolliand, Pierre Groshens

Patent number: 5153049Abstract: The base material for thermobinding interlining is constituted of a woven fabric or of a weft knitted fabric or weft knit. According to the invention, at least the weft of the woven fabric or of the weft knit is in synthetic yarns, for example of 35 to 500 dtex, composed of thin filaments having a unit count less than 1.3 dtex. Preferably, these yarns are textured yarns.The thermobinding interlining is constituted of the woven fabric or of the weft knit, on one face of which dots of thermofusible polymer have been deposited.Type: GrantFiled: October 1, 1991Date of Patent: October 6, 1992Assignee: Lainiere de Picardie (S.A.)Inventor: Pierre Groshens

Patent number: 5065599Abstract: An interlining fabric for providing stiffening to cloth has floats at the surface thereof opposite the surface to be bonded to the cloth, the floats being formed by portions of thread of a fabric body forming a part of the interlining fabric. The fabric has a thermal bonding coating on the surface opposite the floats. A basting needle may be passed between one or more of the floats, and a textile layer, to thereby secure the textile layer to the interlining fabric, and to cloth to which it is bonded in a secure manner and without the basting thread extending through the cloth. A process for producing an interlining fabric comprising knitting a fabric, and inserting threads thereinto having floats.Type: GrantFiled: September 29, 1989Date of Patent: November 19, 1991Assignee: Lainiere de Picardie, S.A.Inventor: Pierre Groshens
