Problems solved by technology

[0002] Outdoor clothing is the necessary protective equipment for explorers, outdoor sports enthusiasts and long-distance travelers. At present, it is mainly an assault jacket made of fabrics produced by Gore in the United States, but its material is made of relatively expensive polytetrafluoroethylene microporous Membrane material is used as a breathable interlayer, so the relevant outdoor clothing is more expensive; in addition, some other manufacturers at home and abroad try to use other materials to replace PTFE materials. Although the breathability has been improved, but because The strength is too low to be used in harsh environments, such as polyurethane, etc.
Or use other preparation processes to reduce costs, but the effect is not obvious

Embodiment 1

[0035] (1) Preparation of functional layer:

[0036] (a) Mixing: Add polyethylene and white oil with a molecular weight of 900,000 and a molecular weight distribution coefficient of 0.9 into a twin-screw extruder, melt, shear, and blend to obtain a mixture, and cast to form a sheet A;

[0037] (b) Longitudinal stretching: After sheet A is cooled, carry out longitudinal stretching to form a longitudinal hole structure to obtain sheet B;

[0038] (c) One-time transverse stretching: Take sheet B and carry out transverse stretching. When stretching, the stretching angle increases stepwise and is divided into 3 stretching orientations. The angle ranges are: first angle 15°, The second angle is 45°, the third angle is 75°, and the stretching temperature is 129°C to obtain sheet C;

Abstract

The invention discloses a high-tensile-strength waterproof moisture-permeable composite fabric material and a preparation process thereof, the composite fabric material is prepared by compounding a base material and a functional layer by an adhesive, and the functional layer is prepared from ultra-high molecular weight polyethylene. According to the invention, through setting the materials and the preparation process in the composite fabric material, the textile fabric is used as a base material, the polyethylene with stronger hydrophobicity is used as a functional layer material, and a nano-scale microporous structure is formed, so that the composite fabric material has better water vapor molecule permeability and moisture permeability, and can well replace the composite material used in the current field; and the base material is subjected to adhesive dispensing in an arrangement manner and is subjected to thermal compounding with the functional layer to prepare the composite fabric material, the tensile strength of the composite fabric material is improved, meanwhile, the composite fabric material has excellent heat retention property and can be well applied to various fields, and the prepared clothes have the characteristics of high heat retention property, high sharp object puncture resistance strength and good moisture permeability.
