A method comprises: coating a high-elasticity coating on a rubber foam or high-elasticity fabric of a wetsuit to form a substrate to be printed; providing a digital printing machine for uploading an image file of a pattern or logo to the digital printing machine; and providing a vacuum system having a sucking platform formed with a plurality of sucking holes through the sucking platform; and laying the substrate to be printed on the sucking platform, whereby upon operation of the vacuum system and actuation of the digital printing machine, the image of the pattern or logo will be digitally printed on the substrate as laid on the sucking platform for successfully digitally printing the patterns on the wetsuits.

A primary backing having a component having a front surface and a rear surface, a second component having a front surface and a rear surface placed adjacent and plane-parallel to the first component, and an optional third component having a front surface and a rear surface placed adjacent and plane-parallel to the second component, wherein the first component comprises a two-dimensional material layer, an extruded sheet, and a non-woven fabric and/or a woven fabric. The second component comprises a three-dimensional structure, wherein the three-dimensional structure is build-up from macroscopic thermoplastic fibers, the fibers cross one another at crossing points and are thermally bonded to one another at their crossing points, and the third component comprises a further two-dimensional material layer, wherein the material layer comprises an extruded sheet, a non-woven fabric, a woven fabric and/or a two-dimensional layer of macroscopic fibers.

A seat molded article and a method of preparing a seat molded article are disclosed. The seat molded article includes: an upper pad formed of polyurethane foam having a thickness in a range of 25 to 50 mm; and an elastic fabric disposed under the upper pad, wherein, in the elastic fabric, a difference in tensile elongation between warp and weft directions is 5.0% or less, and a tensile elongation measured under a load of 20 kgf is in a range of 20 to 40% in the warp and weft directions.

A composite material for garments, such as shapewear and sportswear garments, is formed of an outer layer that is highly elastic with high compression and an inner layer provided on the outer layer and made of a material that is elastic, waterproof and oil proof. The outer layer is a fabric base fabricated from a blend of polyester and spandex. The inner layer comprises a coating of polyurethane (PU) containing nano-titanium dioxide (nano-TiO.sub.2). When used to fabricate a garment, the inner layer of the composite material is adjacent to the body of the wearer when the garment is worn such that perspiration from the wearer's skin and/or skin contact products, such as oil/water based body creams and gels, applied to the wearer's skin are not absorbed by the inner layer and are thereby prevented by the inner layer from being transmitted to the fabric base.

The present invention concerns a method for coating a textile material with a silicone elastomer composition crosslinkable by condensation reactions, to produce a solid silicone elastomer, optionally in a thin layer, on a flexible support that can be made from a textile material, paper, polyvinyl chloride, polyester, polypropylene, polyamide, polyethylene, polyurethane, non-woven glass fiber fabric or polyethylene terephthalate.
