AI Technical Summary

Problems solved by technology

[0003] Most of the current full shading fabrics are coated, but the drape performance and air permeability of the coated fabrics are poor, and the coating is easy to fall off, which affects the shading effect
There are also some curtains that use a multi-layer structure or thickened material in order to achieve a high shading effect, but they cannot meet the simple and light development trend of decorative textiles.

Abstract

The invention discloses a composite membrane, a preparation method thereof, a T-mouth membrane structure for preparing the composite membrane and application of the composite membrane in curtains and composite fabrics. The composite membrane comprises a light-reflecting resin region and a light-absorbing resin region, wherein the light-absorbing resin region is located in the middle of the light-reflecting resin region to form an integrated composite membrane structure; and the integrated composite membrane structure is produced by virtue of a once extrusion molding technique. The composite membrane has the advantages of high membrane strength and good light-shading effect, and a fabric and a light-shading curtain which are prepared from the composite membrane have the characteristics of strong light shading property, lightness, thinness, durability, easiness in preparation and the like.

Description

technical field [0001] The invention belongs to the field of shading materials and applications, in particular to applications such as composite films, fabrics, curtains or other curtains with full shading performance. The invention also relates to a light-shielding composite film, a preparation method thereof and a T-die for preparation. Background technique [0002] In people's daily life, the home environment or public spaces such as hotels, offices, and meeting rooms often need to control the brightness of the room to reduce the troubles caused by sunlight to life and work. In bedrooms, theaters, multimedia rooms, darkrooms and other places that require high light, full blackout curtains are needed. For blackout curtains, not only is it required to be beautiful, but its key indicator is that it should have good shading performance against sunlight. In addition, it is sometimes required to have good fastness properties. [0003] Most of the current full shading fabrics...
