Problems solved by technology

It is common to apply coating agents on chemical fiber fabrics in the market. Although the process is simple and the price is low, due to the coating process, it cannot solve the contradiction between waterproof and moisture permeability.
Therefore, the function of the fabric is limited, making its application field small and narrow

Embodiment 1

[0014] Embodiment 1: A kind of composite textile and its manufacturing process, with ordinary woolen textile fabric as base material, with PU film as auxiliary base material, PU film is hydrophilic type, its thickness is 10-50 μ m, first, choose HL9595 moisture curing as Hot-melt adhesive, heat the cured HL9595 hot-melt adhesive to 150°C, and the viscosity reaches 20,000mpas; flatten the wool textile fabric; flatten the hydrophilic PU film, and preheat, the preheating temperature is 95-100°C; apply the hot-melt adhesive Fabric on hydrophilic PU film, coating weight 25g / m 2 , The coating gap is 25mm; the woolen textile fabric and the hydrophilic PU film are laminated and fused, the lamination gap is 25mm, and then wound, flattened and naturally curled with a pressure of 3bar, and cured in an environment with a temperature of 25°C and a humidity of 50% for 7 days.

Embodiment 2

[0015] Example 2: A composite textile and its manufacturing process, with cotton textile fabric as the base material and PU film as the auxiliary base material. The PU film is hydrophilic and has a thickness of 10-50 μm. First, select the cured HL9640 as the hot melt adhesive, heat the cured HL9640 hot melt adhesive to 100°C, and the viscosity reaches 10,000mpas; flatten the cotton textile fabric; flatten the hydrophilic PU film, and preheat it, the preheating temperature is 95-100°C ; Coat the hot melt adhesive on the hydrophilic PU film, the coating weight is 15g / m 2 , the coating gap is 10mm; the cotton textile fabric and the hydrophilic PU film are laminated and fused, the lamination gap is 12mm, and then wound, flattened and naturally curled with a pressure of 1.5bar, and cured in an environment with a temperature of 25°C and a humidity of 50% for 7 days .

[0016] The fabric of the present invention can be widely used in the medical and health field. Hydrophilic PU fil...

Embodiment 3

[0023] Embodiment 3: A kind of composite textile and manufacturing process, take chemical fiber polyester textile fabric as base material, take PU film as auxiliary base material, select PU film as microporous type, its thickness is 10-50 μ m, firstly, select curing HL9639 as Hot-melt adhesive, heat the cured HL9639 hot-melt adhesive to 70°C, and the viscosity reaches 2000mpas; flatten the chemical fiber polyester fabric; flatten the microporous PU film, and preheat, the preheating temperature is 95-100°C; The glue is coated on the microporous PU film, the coating weight is 5g / m 2 , the coating gap is 0.5mm; the chemical fiber polyester and the microporous PU film are laminated and fused together, the lamination gap is 0.5mm, and then flat and naturally wound, the curling pressure is 0bar, and placed in an environment with a temperature of 25°C and a humidity of 50% to cure for 7 sky. Since the microporous diameter of the microporous PU film is 0.01-0.03nm, the average diamet...

Abstract

The present invention relates to a composite fabric and its production method. The production method includes the following steps: spreading fabric base material, spreading pu film and preheating; selecting and heating hydrosolidification thermosol, coating the thermosol on the pu film, combining the fabric base material and pu film and binding them together, natural spreading and winding, solidifying and obtaining a certain binding strength so as to obtain the invented product.

Description

technical field [0001] The invention relates to a textile and a manufacturing process, in particular to a composite textile and a manufacturing process. Background technique [0002] There are many kinds of textile fabrics. During use, they are usually required to have the functions of heat preservation, waterproof and vapor permeability, so as to meet the needs of different environments. As clothing fabrics, textiles should not only make consumers wear beautifully but also comfortably. Water resistance and moisture permeability are two fundamental and contradictory conditions for creating clothing comfort. In the natural environment, in the process of changing between vapor, water and energy, textiles must meet the requirements of waterproof and moisture permeability. At present, high-density fabrics and coated fabrics are mostly used to achieve this. High-density fabrics use the tiny gaps between microfibers to achieve waterproof and vapor-permeable performance, but their...
