Fabric including low-melting fiber

Abstract

Fabrics including a low-melting fiber are provided. In an embodiment, the fabric includes a regular fiber and a low-melting fiber. The low-melting fiber is directly included in either warps or wefts or both. Alternatively, a blended or plied fiber of the regular fiber and the low-melting fiber is included in either warps or wefts or both. The low-melting fiber has a fusion rate of 30 to 100%. The fabric has a yarn slip length of 0.1 to 2.5 mm.

Description

TECHNICAL FIELD[0001]The present invention relates to fabrics including a low-melting fiber, and more particularly to fabrics including a low-melting fiber whose fusion rate is controlled to achieve both shape stability and environmental stability simultaneously.BACKGROUND ART[0002]In recent years, the application of fabrics has been extended to industrial and living goods as well as clothes. The living goods are exemplified by screens. General applications of screens are window blinds and projectors. Screens for window blinds are fabric products that are installed in houses, hotels, restaurants and other buildings to protect people's private lives and block sunlight from entering the windows. A typical screen for a window blind is produced by cutting a fabric to a predetermined width and rolling the cut fabric on a roll. The screen is designed in such a way that the roll is fixed to the window and the fabric rolls down to cover the window or rolls up to secure a field of view when ...

AI Technical Summary

Benefits of technology

[0021]The fabrics of the present invention do not undergo an additional coating finish that causes the release of volatile substances. Therefore, the fabrics of the present invention are effective as environmentally friendly industrial materials.

[0022]In addition, the fabrics of the present invention provide optimum physical properties that can simultaneously satisfy both flexibility of fabric and stiffness suitable for use as screen materials. As a result, the fabrics of the present invention possess physical properties suitable for use in desired applications.

[0023]Furthermore, the physical properties the fabrics according to the present invention can be appropriately controlled according to intended applications by varying the fusion rate of the low-melting fiber.

Problems solved by technology

However, the method essentially involves an additional coating process.

Another problem of the method is indoor environmental pollution because the screen fabric is installed indoors and the coating material is classified as a volatile organic compound (VOC) in view of its characteristics.

The organic solvent-based adhesive does not penetrate into fabrics, resulting in poor adhesion to the fabrics and leaving a rough feeling after use.

Further, the adhesive is very volatile, contains a number of substances harmful to humans and gives off toxic gases, which cause environmental problems.

This technique can solve the problems of prior art coating methods but fails to review the control of the physical properties of the fabric depending on the fusion rate of the low-melting fiber.

Thus, the fabric cannot be applied to various products and does not possess physical properties suitable for use in desired applications.
