Abstract

An intelligent waterproof fabric, including an inner fabric and an outer fabric, the inner fabric is a fabric with excellent skin-friendly properties, the outer fabric includes warp yarns and weft yarns, and includes an inner core layer and an outer cladding layer, and the inner core layer is water-swellable When the outer layer of the fabric meets water, the hydrophilic short fibers of the outer layer of the warp and weft that are in direct contact with the water absorb moisture quickly , and transmitted to the inner core layer, at this time, the water-swellable filament bundles or short fiber bundles of the inner core layer swell rapidly after contacting water, so that the gap between the warp and weft yarns of the outer fabric disappears, preventing moisture from entering the inner layer Fabric, when the moisture is evaporated by the outside to less than the expansion point of the water-swellable filament bundles or short fiber bundles of the inner core layer, the water-swellable filament bundles or short fiber bundles of the inner core layer shrink, and the warp and weft yarns The gaps between them allow the outer fabric to breathe.

Description

A smart waterproof fabric

technical field

The utility model relates to the technical field of textiles, in particular to an intelligent waterproof 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 waterproof fabric by means of compound interweaving.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an intelligent waterproof fabric, including an inner fabric and an outer fabric, the inner fabric is a fabric with excellent skin-friendly properties, and the inner fabric is cotton Or cellulose fiber pure or blended woven fabric, the inner fabric is in direct contact with the skin of the human body, the outer fabric is a woven fabric, the outer fabric includes warp yarns and weft yarns, and the warp yarns and weft yarns are wrapped The core yarn, the warp and weft yarns include an inner core layer and an outer cladding layer, the inner core layer is a water-swellable filament bundle or a short fiber bundle, and the outer cladding layer is a short fiber aggregate with certain stretchability, so The short fibers of the outer cladding are hydrophilic fibers, and the short fibers in the short fiber assembly of the outer cladding are entangled with each other under a certain twist so as to tightly wrap the inner core layer, and the water-swellable filament bundle or The expansion force of the short fiber bundle is greater than the stretching force of the short fiber assembly in the outer covering. When the outer fabric meets water, the hydrophilic short fibers of the outer covering of the warp and weft that are in direct contact with the water will quickly absorb the moisture and It is transmitted to the inner core layer. At this time, the water-swellable filament bundles or short fiber bundles of the inner core layer expand rapidly after contacting water, so that the gap between the warp and weft yarns of the outer fabric disappears, preventing moisture from entering the inner fabric. When the water is evaporated by the outside to less than the expansion point of the water-swellable filament bundles or short fiber bundles of the inner core layer, the water-swellable filament bundles or short fiber bundles of the inner core layer shrink, and the short fibers of the outer cladding are assembled The body compressive force causes the warp and weft yarns to become smaller in diameter, and gaps between the warp and weft yarns appear, allowing the outer fabric to breathe.

The utility model has the advantages of: adopting the composite interweaving method, a fabric with intelligent waterproof function is provided, which realizes the automatic water blocking of the fabric when it encounters water and the automatic ventilation of the fabric when the water disappears, and realizes the intelligent waterproofing of the fabric.

detailed description

As shown in Figure 1, an intelligent waterproof fabric includes an inner fabric 1 and an outer fabric 2, the inner fabric is a fabric with excellent skin-friendly properties, and the inner fabric is a purely or blended machine made of cotton or cellulose fibers. Fabric, the inner fabric is in direct contact with the skin of the human body, the outer fabric is a woven fabric, the outer fabric includes warp yarn 3 and weft yarn 4, the warp yarn and weft yarn are core-spun yarns, the warp yarn and weft yarn include an inner core layer and an outer cladding layer, and the inner core The layer is a filament bundle or a short fiber bundle that swells with water, and the outer covering layer is a short fiber aggregate with a certain degree of stretchability, and the short fiber in the outer covering layer is a hydrophilic fiber, and the short fiber in the short fiber aggregate of the outer covering layer The inner core layer is tightly wrapped by intertwining with each other under the action of the twist, and the expansion force of the water-swelling filament bundle or short fiber bundle is greater than the stretching force of the short fiber aggregate in the outer cladding layer. The hydrophilic staple fibers of the outer cladding of warp yarn 3 and weft yarn 4 in direct contact absorb moisture quickly and transfer it to the inner core layer. At this time, the water-swellable filament bundle or short fiber bundle of the inner core layer contacts the water After that, it expands rapidly, so that the gap between the warp yarn and the weft yarn of the outer layer fabric 2 disappears, and prevents moisture from entering the inner layer fabric 1. At the same time, the water-swellable filament bundles or short fiber bundles of the inner core layer shrink, and the short fiber aggregates of the outer cladding layer make the diameter of the warp and weft yarns smaller due to the compression force, and the gap between the warp and weft yarns appears, making the outer fabric 2 breathable.

Claims (1)

1. An intelligent waterproof fabric, comprising an inner layer fabric and an outer layer fabric, is characterized in that: the inner layer fabric is a fabric with excellent skin-friendly properties, and the inner layer fabric is pure spinning or blending of cotton or cellulose fiber woven fabric, the inner fabric is in direct contact with the skin of the human body, the outer fabric is a woven fabric, the outer fabric includes warp yarns and weft yarns, the warp yarns and weft yarns are core-spun yarns, and the warp yarns and weft yarns It includes an inner core layer and an outer cladding layer, the inner core layer is a water-swellable filament bundle or a short fiber bundle, the outer cladding layer is a collection of short fibers with certain stretchability, and the short fibers of the outer cladding layer are hydrophilic Water-based fiber, the short fibers in the short fiber assembly of the outer cladding are entangled with each other under a certain twist so as to tightly wrap the inner core layer, and the expansion force of the water-swellable filament bundle or short fiber bundle is greater than that of the outer cladding The stretching force of the short fiber aggregate in the layer, when the outer layer fabric encounters water, the hydrophilic short fibers of the warp yarn and the outer covering layer of the weft yarn that are in direct contact with the water will quickly absorb the water and transfer it to the inner core layer. The water-swellable filament bundles or short fiber bundles of the inner core layer expand rapidly after contacting water, so that the gap between the warp and weft yarns of the outer fabric disappears, preventing moisture from entering the inner fabric. When the water-swellable filament bundles or short fiber bundles of the core layer reach the expansion point, the water-swellable filament bundles or short fiber bundles of the inner core layer shrink, and the compression force of the short fiber aggregates in the outer cladding makes the diameter of the warp and weft yarns Get smaller, and the gaps between the warp and weft yarns appear, allowing the outer fabric to breathe.
