Embodiment Construction

[0030] figure 1 A preferred embodiment of the method of the invention for producing a fibrous textile weave from spinning staple fiber material suitable for producing a flat textile weave in a manner known per se in the textile field, such as making spun yarns, is represented.

[0031] In the conveying direction F, the approximately continuous nonwoven 1 is fed to the processing zone and passed through the processing zone 2 . During the transport through the processing zone 2, a processing template is positioned on one side of the nonwoven 1 and fine jets such as water, saturated steam or air impinge on the nonwoven 1 from the other side (the jet and the processing template are in contact with each other) figure 1 not shown). Owing to the action of the jet stream and the processing template, in the conveying direction F, strip-shaped sparse areas 4 and a plurality of parallel strips 3 alternating therewith are obtained in the nonwoven. After the processing station 2, the str...

Abstract

Filamentous textile structures are produced from a quasi continuous planar nonwoven (1) by subjecting the nonwoven (1) to fluid-dynamic forces, namely in such a way that the nonwoven (1) is split up longitudinally into a plurality of parallel slivers (3) and the fiber structure of the nonwoven (1) is bonded in the slivers. For the treatment with fluid-dynamic forces, the nonwoven (1) is placed for example against a treatment template (10) which is structured in a strip-like manner by perforations (11) and elevations (12) and fine water, saturated steam or air jets (13) are directed against the nonwoven (1) and the template (10). The slivers produced during the treatment with the fluid-dynamic forces can be processed without any further treatment into a planar textile structures or they can be subjected to a further treatment prior to said processing in order to increase their strength. Said further treatment can preferably be performed without any application of additives (false twist, rubbing) or it is a further treatment which can be reversed after the production of the planar structure (treatment with glue). The slivers (3) have a relatively large volume and can therefore be weaved into covering fabrics with relatively low thread densities. They are suitable for example as weft yarns in fabrics for low-quality needs such as fabrics for disposable linens.

Description

technical field [0001] The invention belongs to the field of textile technology and relates to a device and a method as described in the preambles of the independent claims. The method and apparatus relate to fibrous weaves composed of spun staple fiber material. Background technique [0002] Spinning staple fiber materials such as cotton or wool consist of fibers of finite length. In order to produce fibrous structures from these materials, the fibers are usually formed into a flat card web by means of a card, which are subsequently joined to form a sliver. In the sliver, the fibers are no longer randomly placed, but are preferably aligned in the machine direction. The sliver is then converted by drafting and further directional adjustment into an elongated structure in which the fibers are closer to each other and highly parallel than in the card web. The elongated structure is processed by spinning (spinning) into a thread in which the fibers are connected to each othe...
