TEXTILE BAND FOR SOLAR PROTECTION ELEMENT

Abstract

A textile strip used within the technical textiles sector is for a protection or covering element made of a woven fabric, which is produced by perpendicularly crossing threads which extend in a longitudinal or warp direction and threads which extend in a transverse or weft direction. The textile strip includes core-spun threads having a core of elastomeric fibres having viscoelastic properties.

10. The textile strip according to claim 1, wherein the weft is formed of said core-spun threads having a core comprising said elastomeric fibres.

11. The textile strip according to claim 1, wherein it is comprised in a protection or covering element and comprises a region of overlapping fabric which is attached by a permanent attachment.

12. The textile strip according to claim 11, wherein said overlap region joins said textile strip to another textile strip.

13. The textile strip according to claim 11, wherein said threads having the core of elastomeric fibres are arranged perpendicularly to the region of overlapping fabric.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described below with reference to the following figures, which do not limit the scope of the present invention and in which:

[0019] FIG. 1 shows an embodiment of the textile protection element used as a roller awning.

[0020] FIG. 2 is a schematic plan view of a fragment of the textile protection element produced by joining two textile strips, specifically the region where two textile strips overlap is shown.

[0021] FIG. 3 is a schematic view of an embodiment of a core-spun thread.

[0022] FIG. 4 is a graph showing stretch under a constant load and elastic recovery of a textile strip composed of core-spun threads having a core of elastomeric fibres.

[0023] Detailed Description of the Preferred Embodiment As shown in FIG. 1, the textile element of the present invention can be used as an awning. Said awning is formed by joining the textile strips -1-, -2-, etc. When the awning is to be stowed, it is rolled up around the cylinder -3- by the rotary action of said cylinder.

[0024] As shown in FIG. 2, the textile strips -1- and -2- are joined by partially overlapping the respective longitudinal ends -4- and -5- thereof, creating an overlap region -6- which extends in parallel with the central longitudinal axis -7-. In the region -6-, permanent attachment means, such as stitching or welding, among others, are used. Because the protection element is thicker in the region -6-, when said element is rolled up, stresses are produced which lead to the appearance of creases -8-, -9-, which are visible in the unrolled position of the protection element.

[0025] As shown in FIG. 3, the core-spun threads which make up the textile element comprise a core -10- and a sheath -11-. The core -10- comprises a plurality of elastomeric fibres, while the sheath -11-, which covers the core, comprises a plurality of acrylic fibres.

[0026] As shown in FIG. 4, the graph shows the stretch under a constant load and the elastic recovery of a textile strip composed of core-spun threads having a core of elastomeric fibres. The timescale is shown on the x-axis, while the percentage of stretch of the strip is shown on the y-axis, which percentage of stretch is calculated using the formula:

% stretch=[(final lengthinitial length)/initial length]100

[0027] At the starting time -12-, an extension force is exerted on the textile strip such that instantaneous initial stretching of said strip is produced. After the starting time -12-, the strip is stretched under a constant load, said stretching under a constant load increasing until it reaches a constant value at the time point -13-. At said time point -13-, the extension force ceases to be exerted on the textile strip, such that from the time point -13-, the elastic recovery of the strip begins. During elastic recovery, the stretch decreases with time until maximum elastic recovery -14-, of more than 99%, is reached.

[0028] Although the invention has been described with respect to preferred embodiments thereof, these should not be considered to limit the invention, which will be defined by the broadest interpretation of the following claims.
