  • Patent number: 5993918
    Abstract: The present invention relates to a process for manufacturing a thermobonding interlining in which dots of thermofusible polymer of mean thickness E are deposited on the front face of an interlining support, chosen from textile and non-woven supports, and one of the faces of the support is subjected to electron bombardment, wherein, as the dots of thermofusible polymer contain a radical activator and are bereft of photoinhibitor, the depth of penetration of the electrons in the dots of thermofusible polymer is adjusted in order to obtain a modification of the physico-chemical properties of the thermofusible polymer, chosen from the melting temperature and viscosity, over a limited thickness e with respect to the mean thickness E.

  • Patent number: 5924179
    Abstract: 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.

  • Patent number: 5898941
    Abstract: The present invention concerns a reinforcing base fabric (1) for fabrics, cloths, clothing, consisting of a weft knit fabric (2) comprising an insertion of reinforcing and stabilizing yarns (3) extending in the direction of the weft between the rows, the reinforcing and stabilizing yarns being flat and free from crimp stress.

  • Patent number: 5827579
    Abstract: The invention concerns a process for manufacturing a fusible interlining (1) comprising a base fabric (2), a thermofusible first layer (5) applied on one of its faces (3) referred to as the front face, and a thermofusible second layer (7) applied on the rear face (4) of the base fabric (2), characterised in that the first layer (5) is deposited on the front face (3) of the base fabric (2) by means of a first screen printer (9); the second layer (7) is deposited on a transfer roller (11) by means of a second screen printer (10); the points (8) thus obtained are transferred onto the rear face (4) of the base fabric (2), the depositing of the first layer (5) and the transfer of the second layer (7) being performed simultaneously so that the points (6, 8) of the layers (5, 7) lie opposite to one another on the cross-sectional plane.

  • Patent number: 5820928
    Abstract: The invention concerns a process for manufacturing a fusible interlining (1) wherein a base fabric (2) receives a coating of thermofusible polymers distributed in points (3), characterised in that the following steps are successively carried out: depositing a sublayer (5) of polymers on a transfer medium (6, 7) comprising a regular and smooth surface; transferring the points thus obtained onto the base fabric (2); applying the thermofusible particles (10) on the sublayer (5); running the fusible interlining (1) thus obtained through a heating and/or radiation chamber (12).

  • Patent number: 5695598
    Abstract: The invention concerns a bonding press for bonding, onto a cloth, a fusible interlining comprising a base fabric associated to one or more thermoadhesive and/or thermocross-linkable adhesive polymer layer(s). According to the invention, the interlining/cloth complex trapped between the two conveyor belts (1, 2) passes through a second area (B) heated to a temperature greater than or equal to the melting temperature of the polymer(s) so as to allow for the chemical coupling reaction of the thermocross-linkable polymers in the interlining's adhesive layer.

  • Patent number: 5510142
    Abstract: The invention concerns a process for manufacturing a composite base fabric intended for the reinforcement of a waistband which is elastic in the direction of the warp, characterized in that it comprises the steps of using a warp knitting machine with weft inserts to produce a composite base fabric comprising a warp knit fabric, a fabric substrate inserted in the warp knit fabric, elastic yarns which undergo a tensional elastic deformation during the knitting, weft yarns; thermofixing the composite base fabric thus obtained; depositing a film forming coating comprising a cross-linkable resin on the face of the fabric substrate in contact with the elastic yarns and the weft yarns; drying and cross-linking the film forming coating; submitting the composite base fabric to a relaxation treatment
