Abstract

An intelligent sunscreen fabric, including warp and weft yarns, wherein the warp and weft yarns include an inner core layer, a middle layer and an outer cladding layer, the inner core layer is a filament fiber with a hollow structure and certain elasticity, and the middle layer is a thermally expanded short fiber bundle, The expansion temperature of the heat-expandable staple fiber bundle is between 20-40 degrees centigrade, and the outer covering layer is a fabric formed by interweaving short-fiber yarns with certain stretchability. When the fabric is irradiated in the sun, the heat-expanding short fiber bundles will expand under the action of light, so that the gap between the warp and weft yarns of the fabric will disappear, blocking sunlight. When there is no sunlight or the irradiation temperature is lower than the expansion temperature, heat will expand. The staple fiber bundle shrinks, and the compression force of the staple fiber yarn in the outer covering fabric makes the diameter of the warp and weft yarns smaller, and the gap between the warp and weft yarns appears, making the fabric breathable.

Description

A smart sunscreen fabric

technical field

The utility model relates to the technical field of textiles, in particular to an intelligent sunscreen fabric.

Background technique

With the development of social economy and the improvement of people's living standards, people's consumption concept is constantly updated, and they pay more and more attention to the quality of life and living environment. The requirements for sun protection, antibacterial, antistatic, hand feeling, quality, and aesthetics are constantly increasing. Aiming at this, the utility model provides an intelligent sun-proof fabric by means of composite interweaving.

Contents of the invention

The purpose of the utility model is to provide an intelligent sunscreen fabric by adopting a composite interweaving method.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an intelligent sunscreen fabric, including warp yarns and weft yarns, the warp yarns and weft yarns include an inner core layer, a middle layer and an outer cladding layer, and the inner core layer has a hollow structure The filament fiber has a certain elasticity, the middle layer is a heat-expandable short fiber bundle, the expansion temperature of the heat-expandable short fiber bundle is between 20-40 degrees Celsius, and the outer cladding layer has a certain A fabric interwoven with stretchable staple fiber yarns, the expansion force of the heat-expandable staple fiber bundle is greater than the stretching force of the staple fiber yarns in the outer covering fabric, and the stretching force of the staple fiber yarns in the outer covering fabric is greater than The elasticity of the filament fibers in the inner core layer.

The utility model has the advantages that: a fabric with intelligent sun protection effect is provided by adopting the composite interweaving method; when the fabric is worn and irradiated in the sun, the heat-expanding short fiber bundles will expand under the action of light, so that the warp and weft yarns of the fabric The gap between them disappears, blocking the sunlight. When there is no sunlight or the irradiation temperature is lower than the expansion temperature, the heat-expanding short fiber bundle shrinks, and the compression force of the short fiber yarn in the outer covering fabric makes the diameter of the warp and weft yarns smaller, and the warp and weft yarns The gaps in between appear, making the fabric breathable.

Detailed ways

As shown in Figure 1, an antistatic single-layer fabric of the present invention comprises a warp yarn 1 and a weft yarn 2, wherein the warp yarn 1 and the weft yarn 2 comprise an inner core layer, an intermediate layer and an outer cladding layer, and the inner core layer is a long hollow structure. Silk fibers, filament fibers have a certain degree of elasticity, the middle layer is heat-expandable short fiber bundles, the expansion temperature of the heat-expandable short fiber bundles is between 20-40 degrees Celsius, and the outer cladding is interwoven with short-fiber yarns with certain elasticity In the fabric, the expansion force of the heat-expanding short fiber bundle is greater than the stretching force of the short fiber yarn in the outer covering fabric, and the stretching force of the short fiber yarn in the outer covering fabric is greater than the elasticity of the inner core layer filament fiber.

In the spinning process, the corresponding warp yarns and weft yarns are first spun respectively, and then the obtained warp yarns and weft yarns are interwoven to obtain corresponding fabrics.
