Problems solved by technology

The laminate of the fabric and the ordinary porous resin film has obvious through-holes when laminating, so the film is prone to breakage after lamination, the hand feels hard, and there is no windproof but only breathable phenomenon, which affects the lamination cost and The process stability, especially the control precision of the tension and the late application have brought great pressure, hindering the development of the market

Embodiment 1

[0053] The 8μm convex surface hole diameter of 0.2mm polyester derivative needle-rolled microporous thermal film and 170g / m2 polyester four-way stretch knitted fabric are bonded to the point-shaped micro-concave plate with reactive hot-melt polyurethane glue, and the weight of the glue is 10g. / m2, production line speed 10m / min, cooling and winding. Carry out glue ripening again. Obtain a fabric with a smooth surface and no sticky touch. The softness ISO 17235 test result is 3.4, the peeling force GB8808 test result is 6.0N / 15cm, and the moisture permeability GB / T12704.1 test result is 3500g / m 2* 24h, the air permeability GB / T 5453 test result is 5-15mm / s, this example proves that the needle-rolled film plays the role of windproof and breathable, and also because of the existence of the hole, there is a difference in the internal and external humidity, glue penetration and pore blockage get relief.

Embodiment 2

[0055] The glue grammage of embodiment one is 15g / m , production line speed 10m / min, cooling winding. Carry out glue ripening again. Obtain a fabric with a smooth surface and no sticky touch. The softness ISO17235 test result is 3.6, the peeling force GB8808 test result is 8.0N / 15cm, and the moisture permeability GB / T 12704.1 test result is 3200g / m 2* After 24 hours, the air permeability GB / T 5453 test result is 5-15mm / s; this embodiment shows that the glue increases, and there is no glue seepage, and there is no large-scale clogging of the holes.

Embodiment 3

[0057] The production line speed of embodiment one is increased to 30m / min, cooling and winding. Carry out glue ripening again. A fabric with a smooth surface and no sticky touch was obtained. The softness ISO 17235 test result was 3.7, the peeling force GB88088 test result was 6.0N / 15cm, and the moisture permeability GB / T 12704.1 membrane surface test result was 3300g / m 2* 24 hours, the air permeability GB / T 5453 film surface test result is 5-15mm / s; the increase in production speed, the glue does not appear to leak when the glue is not completely cooled, and does not have too much impact on product performance.

[0058] Embodiment four, five, six

[0059] The convex surface of the 5, 10 μm, 12um polyester derivative needle-rolled microporous film and the polyester four-way stretch knitted fabric with a weight of 170g / m2 are laminated with a reactive hot-melt polyurethane adhesive for point-shaped micro-concave plates. Gram weight is 10g / m2, production line speed is 10m / min...

Abstract

The invention discloses a laminate of a resin thin film prepared by a needle punching method. The laminate comprises at least one layer of microporous resin thin film with straight-through holes in convex shapes, wherein the aperture of each straight-through hole is 10-1000 mu m and the thickness of the microporous resin thin film is 1-500 mu m; at least one layer of fabric; and a bonding layer which is positioned between the microporous resin thin film and the fabric and formed by glue. In the laminate disclosed by the invention, the gram weight of the fabric is 1-500 g / m<2>, and the gram weight of the bonding layer is more than 0.1 g / m<2>. The laminate disclosed by the invention has excellent windproof, breathable, and moisture permeable differential performance, smooth appearance without wrinkles, and soft handfeel.

Description

technical field [0001] The present invention relates to a kind of microporous resin air-permeable film laminate and its preparation method; More specifically, the present invention relates to a kind of microporous resin film, fabric and bonded laminate, Composite and its laminating preparation method. Background technique [0002] At present, 2-layer or multi-layer composite fabrics are composited with non-porous resin films and fabrics, or directly composited with fabrics. If the composite fabric obtained by laminating the non-porous film and the fabric is used, although the actual windproof effect is achieved, the moisture permeability function of the product is reduced, and the air cannot pass through, is not breathable, and the wearing comfort is relatively poor. If the fabric is laminated against the fabric, the product does not have an intermediate film layer to block the wind, it is completely breathable and not windproof, and the product is easy to seep into the sur...
