Fiber molding

A process for producing a thermoformable polymer/fiber composite.

Thermodeformable polymer/fiber composite

The invention relates to a process for producing fiber composite moldings comprising (i) a thermally crosslinkable fiber composite layer as backing layer, and (ii) a thermoplastic fiber composite layer as overlayer, by mutually superposing the fiber composite layer (i) comprising a thermally crosslinkable binder in the unhardened state and the thermoplastic overlayer (ii), and, in a molding press, converting them to the desired form and thermally crosslinking the same, which comprises a higher temperature of the first contact area of the molding press, where this has contact with the backing layer, than of the second contact area of the molding press, where this is in contact with the overlayer.

Binder for granular and/or fibrous substrates.

Binder for granular and/or fibrous substrates

The invention provides an aqueous binder for granular and/or fibrous substrates, said binder comprising, as active constituents, a polyamine and a saccharide compound.

Aqueous binder for granular and/or fibrous substrates

Aqueous binders for granular and/or fibrous substrates are based on polyacids and polyols.

Aqueous binder composition for granular and/or fibrous substrates, where the binder contains i) a copolymer constructed from ethylenically unsaturated monomers; and ii) lignin.

Aqueous binder composition

The invention relates to a fixable nonwoven interlining material for use in the textile industry, comprising at least one melt-spun fiber layer and at least one additional fibrous material layer, the fixable interlining material being provided with an adhesive substance at least in partial regions. A particularly high elasticity of the fixable interlining material is achieved by the fact that the melt-spun fibers are composed of an elastic fibrous material, and the at least one layer of fibrous material is composed of staple fibers, and the at least one elastic melt-spun fiber layer and the at least one staple fiber layer are laid one on top of the other in the form of a flat unbonded fiber fabric, and are subsequently bonded by use of a bonding step known as such.

Fixable nonwoven interlining material used in the textile industry

The invention relates to a textile fabric having a coating composed of two layers of thermoplastic hot-seal adhesives of differing compositions applied one on top of the other, the second hot-seal adhesive, which is applied to the first, having a melting point of &#x3e;135&#xb0; C. and a melt flow index (MFI) value of 50 to 250 g/10 minutes (190&#xb0; C./2.16 kg). The invention further relates to a method for producing a textile fabric, comprising the following steps: a) producing a textile fabric using a textile fabric manufacturing technique; b) applying a layer of a first hot-seal adhesive to the textile fabric; and c) applying a layer of a second hot-seal adhesive to the textile fabric so as to d) form a layer of the second hot-seal adhesive over the layer of first hot-seal adhesive, the second hot-seal adhesive used having a melting point of &#x3e;135&#xb0; C. and a melt flow index (MFI) value of 50 to 250 g/10 minutes (190&#xb0; C./2.16 kg). The textile fabrics may be used as interlining or lining material which can withstand stress during care treatment.

Textile fabric with improved finish, production and use thereof

A fusible interlining includes a textile interlining web coated with a plurality of double-layered adhesive dots on a first side of the textile interlining web. Each of the plurality of double-layered adhesive dots includes a bottom dot facing the interlining web and an upper dot disposed above the bottom dot. Each bottom dot includes a binder paste containing 50 to 95 percent by weight of an acrylate binder dispersion having a glass transition temperature T&#x3c;room temperature and 5 to 50 percent by weight of a substance that is one of an epoxy resin having an epoxy equivalent weight of 500 to 4000 mVal/kg and a copolymer of acrylates and monomers with at least one glycidyl side group. Each bottom dot may further include 0 to 20 percent by weight of a hardener. Each upper dot includes at least one of a copolyamide, a copolyester, a thermoplastic polyurethane and a polyolefin. A ratio of a mass of the bottom dot to a mass of the upper dot is from 1:0.5 to 1:5.
