Description

ebe made of synthetic fibers, especially for floor coverings, "upholstery fabrics and molton

The price increase relates to a Gev / ebe. made from synthetic fibers that are spun in a two-cylinder process vtrA mainly consist of waste from man-made fiber production and reprocessed material.

In the case of the previously known carrier fabrics of the above type, jute was mainly used. This has the disadvantage that it loses up to 40 ^ of its tensile strength when needling. This is because the stubborn jute fibers of the needle cannot escape, are pierced and thus partially destroyed. This disadvantageous phenomenon does not occur with the design that is hereby registered for protection. The individual parsers are that are spun in Zweizylindersyinnverfahren are so smooth that it can deflect under the Ivadel respectively, without zerstochen be zv. On the contrary, they wrap around the piercing needle or the needled fiber material pulled into the ground by this needle, as it were like a collar. The tensile strength of the carrier fabric is up to 100%.

When dyeing thread tiles, needled onto a jute carrier fabric, it often causes the brownish jute color pigment to bleed out and simultaneous drawing of this color pigment onto the needled fiber material. This can result in discoloration and it is often a slightly brownish gray, especially in the case of piece dyeing Veil and thus a slight clouding of the hue, especially in light colors. This has these disadvantages fabric registered for protection does not apply. ^ s is on the contrary possible, in each case, the carrier fabric is synthetic To choose fibers with which it is also needled in the finished product afterwards. The same color is always applied to the carrier fabric like on the needled fiber material. The hue remains obtained perfectly clear when the piece is dyed. It is also

show that jute fabrics, due to their ability to absorb moisture, produce boldness when they are damp, or when they are accidentally wetted with warm water without drying. Insofar as tiles are cut from the panels, they easily have a barrel instability in the case of jute backing fabrics due to this moisture content. The dimensional stability is therefore better with backing fabrics made of synthetic fibers.

The fabric registered for protection has significant advantages over carrier fabrics made of synthetic sinless threads or glass. Fe should not come in short to these either, but should open up additional opportunities. This is given because? the fabric made of synthetic fibers, produced in the IjSseizylinder — ijDijia method, is softer and more voluminous with the same &&& ± £ hi than fabric made from synthetic enctiosal threads and glass. This enables a better connection of the individual strands in the fabric and the needled to be produced, and the sliding fastening, which is unavoidable for fabrics made of synthetic continuous threads and glass, can be dispensed with due to the crimping of the individual fibers and the intimate intertwining of the fibers, it can be pushed sufficiently in. In the finished needled state, however, it has the same chemical-physical properties as these two other qualities mentioned.

The production of the Geivebes takes place according to the previously known, classical "weaving method, usually and most advantageous in "! uchwinder or twill weave.

Claims (4)

Protection claims 1.) Synthetic carrier fabric especially for floor coverings. Upholstery fabrics and purple tones, characterized in that the outer threads from which the fabric is made are made from fully synthetic fibers, preferably from polyacrylonitrile polyester or polyamide (based on Uylon 66) and are spun using the cylinder process. 2.) carrier web according to claim 1, characterized in ₃ that it is preferably obtained from the same material from ÜSM the needled fiber material consists aweh and to evenly stain with this in the same dyeing process. 3.) carrier fabric according to claim 1, characterized in that it dimensionally stable, rot-proof and resistant to bacteria. 4.) carrier fabric according to claim 1, characterized in that äaS it due to its larger volume a light and intimate "interweaving" forms with the fiber material to be needled and that on a fixed sliding equipment of the G-eweb can be dispensed with.
