Textile slats for sun protection or Renner blinds

The object of the innovation are slats for sun protection or Room divider blinds made of textile strips.

Sun protection devices are known which consist of several larvae arranged vertically one behind the other can be pushed together to form a "package", but can also be pulled apart at a certain distance, that you can dampen the incident light as you wish through any angular position. These lamellar leaves exist, for example made of fabrics that are coated with plastics through and through. They often appear paper-like and flaoh, by no means give such a valuable look, also in terms of their color design, like textiles. In addition, it has been observed that this often occurs with bend in direct sunlight.

According to the innovation, slats for sun protection or room divider blinds are now proposed, which are made of textile strips made of woven, knitted or other textile fabrics, for example nonwovens made of melt-spun continuous filaments,

synthetic yarns, fibers or threads, being in the transverse direction A wire made of polyamide or a high molecular weight linear polyester is incorporated into the textile strip is.

This wire - for example in the form of a polyamide monofilament with a diameter of 0.3-0.5 mm - gives the lamellas the required high degree of rigidity in the transverse direction and is worked in according to the type of textile strip, for example in a fabric with the weft. The fabrics, knitted fabrics or other textile fabrics required to produce the lamellae are made from yarns, fibers or threads made from acrylonitrile polymers, polyesters or light-stabilized polyamides. Modaeryl fibers or fibers made from syndis-tactical polyvinyl chloride can also be used.

These lamellas in accordance with the innovation meet the following requirements:

Absolute dimensional stability under different climates, good lightfastness of the colors, good lightfastness of the substance (no significant reduction in strength due to exposure to light) and easy maintenance, e.g. B. by household laundry without significant shrinkage occurs.

Contrary to the coated lamellas currently in use the design options of the textile slats are great versatile. You can bring them in plain colors, for example, with both sides being kept in different colors. To increase the light reflection, for example, one side facing outwards can be in white, the other side facing the room be kept colored. However, any other pattern, mainly in stripes, but also in the jacquard technique, is possible.

The arrangement of a blind can be done in such a way that a bracket is attached in the upper part (which may be can be washed), which in the guide = and the rotating device of the blind rail engages. Weights can be set at the lower end, which are connected to each other by spacer chains. The blind leaves can also hang freely.

The enclosed sample shows a section of an innovation according to the invention Lamella made as follows:

Weight:

approx. 96 threads / cm in the finished tape 6 double picks (12 single picks) / 1 cm in the finished tape
Nm 50/2 3-cyl «yarn made of:

Each individual shot consists of a folded (doubled) material, namely:

1 thread Nm 50/2 3-cylinder thread (like warp thread) 1 polyamide special wire 0.5 mm (each double weft therefore contains 2 threads of 3-cylinder yarn and 2 polyamide monofilaments)

The fabric was based on upper and lower warp in positional relationship 1: 1 built up in one piece, the four-leg warp cross twill was used as a binding chosen with counter-binding sub-chain. By the warping sequence 1: 1 it is thus possible to keep both sides of the tape in different colors.

The binding (binding cartridge) is shown in Fig. 5)
