Innovative processes for the weaving of stretch fabrics for technical textiles

الملخص EN

Along with all the developments in the different methods of textile production, technology and skills are also developing, which in turn pushes productivity forward.

Functional design and high performance of the fabrics, specially intended for mobiltech, represent the main demand of safety guarantee.

The vehicle seats are used up during the time life of the car, as they are difficult to change or repair their upholstery.

Because of this reason, many specified characteristics have to be available in them; dimensions stability and durability play important roles.

Both of these characteristics, in essence, depend on elastic properties of the fabric.

Hence, the study of elasticity of fabrics is important both from theoretical and practical aspects.

This present paper aims at the utilization of different textile materials on the weaving process to produce creative and functional effects, as well as establishing the influence of structural parameters on the tensile properties of the fabric.

The study spots the light on the dimensional stability of the fabric which measures its extent to keep its original dimensions subsequent to its manufacture.

It is possible for the dimensions of seat-fabric to increase or decrease according to the applied forces during their usage.

When the textile material is stretched by a force that is below the level of its breaking strength and then is allowed to recover, it doesn’t immediately return to its original length.

The recovery time depends on the physical properties of the fabric and on the other side the time at which the force is applied on the fabric.

The extent of recovery from the extension is a property, which is dependent on the type of material, which held at a given extension for a fixed length of time before removal of the force, the elastic recovery increases with time, rapidly at first and more slowly later.

The used materials for warp and weft yarns of the seats have to be more elasticity and the fabric structures also have to be built with this a practical point of view.

As it is known, that the percentage recovery decreased steadily with increasing extension of the material up to the yield point where the recovery decreased sharply.

For this reason, the tensile strength and extension of the fabric structures have to be studied in this paper.

Whole allows a better comparison of textile materials to be made as it contains more information about the behavior of the material under stress than do the simple figures for tensile strength and extension.
