Problems solved by technology

[0003] Coatings of different materials on the surface of the fabric can change the characteristics of the fabric. Traditional fabric coatings can effectively prevent moisture and mildew. However, these coatings have much higher thermal conductivity than fabrics, so the thermal insulation properties of textile coatings relatively unsatisfactory

Abstract

The invention provides a negative pressure heat insulating coating device, which includes a first coating extrusion device, a second coating extrusion device as well as a first scraper and a second scraper both equipped with temperature adjusting devices, wherein the first coating extrusion device includes a first coating extrusion sprayer arranged on the surface of fabric; pulse air holes are formed in the inner side of the first coating extrusion sprayer and include a center air outlet and an annular air outlet surrounding the center air outlet; and the center air outlet and the annular air outlet are concentrically arranged; the temperature of the center air outlet is lower than the freezing point; outlet air temperature of the annular air outlet is identical to the coating temperature inside the first coating extrusion sprayer; the first scraper, the second coating extrusion device and the second scraper are sequentially arranged on the first coating extrusion sprayer in the transmission direction of the fabric. The negative pressure heat insulating coating device enables the coating of fabric to be endowed with excellent heat insulating effect as the coating of fabric is filled with negative air bubbles through the pulse air holes.

Description

technical field [0001] The invention relates to the field of textile coating equipment, in particular to a generating device for a textile coating thermal insulation structure. Background technique [0002] Textile coating forms one or more layers of film on the surface of the fabric through adhesion, which can not only improve the appearance and style of the fabric, but also increase the function of the fabric, making the fabric waterproof, water pressure resistant, flame retardant, antifouling and shading reflection, etc. special function. The two most widely used methods of fabric coating are direct coating and transfer coating. Direct coating is to flatten the fabric to form a uniform plane, and then pass it under a stationary scraper. Direct coating is mainly used for fabrics woven from filament yarns such as nylon or polyester. Transfer coating is where the polymer is applied to a release liner to form a film which is then pressed onto the fabric, in this method the...
