Embodiment 1

[0052] Example 1: The fabric of the composite woven fabric on both sides of the functional film

[0053] The fabric of functional membrane double-sided composite woven fabric is mainly suitable for men's windbreaker or jacket. Three-layer composite fabrics for high-end windbreakers and rainproof and moisture-permeable jackets require a flat surface, with a little elasticity in the warp direction, and obvious elasticity in the weft direction for sports comfort. Reach 2000g / square meter x24h (the expression method of moisture permeability performance parameters refers to the amount of water vapor that can pass through per square meter of fabric in 24 hours under specific instruments and methods is greater than 2000 grams), water pressure greater than 10000mmH2O (water pressure resistance reaches 10000mm water High pressure without damage or permeable water pressure unit), the color fastness to dry and wet friction exceeds 3.5, the wear resistance exceeds 4, and the square gram w...

Embodiment 2

[0072] Embodiment 2: The fabric of functional membrane double-sided composite knitted fabric

[0073] This type of fabric is used to make outdoor sweatshirts and has the advantages of windproof, breathable, moisture-permeable and waterproof.

[0074] The specific production method of the fabric of the composite knitted fabric on both sides of the functional film is as follows:

[0075]In the above step A, the surface layer fabric 1 is a knitted fabric. When weaving the knitted fabric as the surface layer, use a 30-inch 44-needle double-sided circular machine weaving gray fabric from Xiamen PILOTELLI Company, use a plain jersey weave for the structure, and use polyester for the yarn DTY15D / 12F network yarn, the weaving wire length is 0.1826 cm / turn, and the unmachined weight is 20 kg / roll.

[0076] When overflow dyeing, first add degreasing agent, put hot water at 84-92 degrees into the cloth, then raise the temperature to 94 degrees and keep it warm for 15 minutes, then cool ...

Embodiment 3

[0088] Embodiment 3: The fabric of the two-sided composite warp-knitted and weft-inserted printed cloth of the functional film

[0089] This kind of fabric is used to make square down fashion down jacket, which has the advantages of windproof, breathable, moisture-permeable and waterproof.

[0090] In this embodiment, the specific production method of the fabric of the two-sided composite warp-knitted and weft-inserted printed cloth of the functional film is as follows:

[0091] In the above step A, the surface layer fabric 1 is a warp-knitted weft-inserted printed cloth, and when weaving the warp-knitted weft-inserted printed cloth as the surface layer, the warp-knitted weft-inserted machine of the HKS model 28 needles of Karl Mayer is selected. Weaving gray fabric, the warp and weft yarn specifications are PESDTY 30D / 24F X PES DTY 50D / 48F, the width of the upper machine is 86 inches, the weft density of the upper machine is 17.5 pieces / cm, 12 / 10 two-needle warp flat weave, a...

Abstract

The invention relates to a functional film double-sided composite fabric production method. The production method comprises the following steps of: processing a first double-point coating on a surfacelayer fabric through a double-point coating process; processing a second double-point coating on an inner layer fabric through a double-point coating process; using a three-layer unreeling compound machine for hot-pressing and compounding. The method comprises the following steps of: adjusting the parameters of hot-pressing and compounding of the three-layer unwinding compound machine; laying thecoating of the inner layer fabric face down on the cloth feeding conveying grid belt and putting it on the cloth feeding conveying mesh belt; putting the functional film on the roll-out position, andputting the functional film on the cloth-feeding mesh belt; laying the coating of the surface layer fabric face down on the cloth-feeding mesh belt; heating the surface temperature of the roller cylinder of the three-layer unwinding compound machine to a set temperature, and starting the multi-function machine, so that the first double-point coating and the second double-point coating are compounded on both sides of the functional film, and the winding is to be fully cooled. The production method disclosed is free of solvent and is extremely small in pollution. The invention also relates to afunctional film double-sided composite fabric.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fabric and a production method of a functional membrane double-sided composite fabric. Background technique [0002] Functional membranes (such as PU membranes, PUR membranes, PTFE membranes, etc.) combined with fabrics to form functional performance fabrics are widely used. It can have a variety of functions that a single fabric does not have, such as windproof, warm, moisture permeable, waterproof, breathable, anti-biochemical, etc., without losing the appearance, feel and mechanical properties of the fabric. [0003] There are two common ways for film and fabric to be combined, one is liquid solvent-containing glue compounding, and the other is hot melt adhesive (PUR, COPA, COPES) compounding. [0004] The adhesive (glue or hot melt adhesive) exists in two forms on the surface of the two substances to be bonded: point bonding and surface bonding. Point-like compounding me...
