Description

The invention relates to textile products made by Steppes are produced and Vex-xaiiren for the production of such Textile products. More specifically, the invention relates to textile products in which the running in one direction Threads across the threads running in the other direction to be quilted. The invention relates even more precisely to textile products, in which a non-woven fibrous filler is stabilized and reinforced by means of stiffeners on the the filler is quilted with transverse threads. In particular, such textile products serve as filter media »

In its preferred form, the fabric is called Filter media processed. One main application is in filtering the sewage to keep our streams, brooks and lakes clean by removing the suspended matter. Have for this purpose nonwoven fibers formed into a nonwoven fabric are useful and proven cheap, with the fibers in the fleece wi-

often called Heck threads by the way, aui which they are bound _ö ewöhnlich in the products. The stiffeners are generally relatively long threads that are brought into a common area or surface for their installation in the finished product by means of a basin. Filler is then placed on the back threads and with the help of a sewing machine that uses threads other than quilting threads, it is quilted onto the back threads. In many cases, the threads are then connected to one another, for example by means of an applied adhesive.

A variety of sewing stitches can be used within the scope of the invention, but in general a stitch is preferred in which two sewing threads are used for one chair, wherein the one Steipfadan on one side of the product and the other stitching thread on the other side of the product runs along. The Textilerzeugnia can daduioh double-sided be made; that means that the product is on. the two sides can have different surface properties.

As filter material has fabric of the invention to even more advantages because of its non-woven J ¹ ULI substance. The filler preferably consists of fine fibers of much smaller diameter than required for weaving. These fibers form the filter in an arbitrary distribution and provide a relatively high permeability, but form relatively small forums. The total passage width of the filter: is therefore large and allows a large volume of filtrate to pass through, while the individual openings or pores are small and hold a large proportion of the solids Filler water repellent and

The cotton can be pretreated accordingly to make a & s textile product water-repellent and water-resistant close. The product can also contain mineral or metal fibers.

For many purposes, for example as decorative fabrics for upholstery or curtains, the textile products according to the invention have the advantage of being different from woven fabrics in terms of the outside and feel.

and the pelvic threads are chained together, making the filler is stitched to the pelvic threads. Preferably, the transvereal movement of the jaw head and aie Execution of the stitches controlled in such a way, aaü the stitches uic-t on the pelvic threads but only between the stern threads. This prevents the pelvic threads from piercing and their strength suffers in the process. You can do it Piercing of the pelvic threads also daaurch- veriaeiaen that jj.an a lla ^ el is used which is too blunt to penetrate the pelvic threads. This is particularly effective when the fieckfäaen are single-threaded, i.e. if they consist of a single wire, so to speak.

After each crossing of the machine head, the chopping threads are pushed forward along with the pull fabric by a certain distance in order to provide the desired distance between the backs. The finished product is then taken up on a take-up roll 38. Brakes are usually provided on the reels 22, which resist the advance of the take-up reel 38 and thereby hold the Beck threads 12 at an appropriate tension, so that these during ues. Quilting processes are essentially stretched and held in parallel in a basin 24.

careful attention should be paid to the drained bodies not to be blocked or covered in the product. For other purposes, enough plastic can be added to all To -close openings, 'including those in quilting resulting holes. The paddle holes can also be made smaller or eliminated by removing the filler all around the It has pinholes tipped. This can be done by feeding one measured amount of heat happen, for example during drying of the plastic.

There are several alternative ways of making the fabric. So know, for example, the pelvis threads looped around the peg at the ends of a pelvis

and the products can, instead of being lax, as in fig. 4, as individual mats are stapled together. Alternatively, it is often desirable to produce an endless belt, for example for a pourdrinier machine. In these In some cases, the product can be produced by means of the device shown in FIG.

At least One of the bolts is adjustable, for example with the aid of movable arms 42 », by the appropriate length for all closed Loop aer Beckfäden 12 to be able to adjust and the Beckfäden keep under proper tension. If aie pelvic threads 12 are self-contained, it may be desirable they are individually to be spleisoenj in this case the threads are preferred at various points along ae3 endless belt spliced so that the tape is not tied to a special watch for each individual stretching line.

The upper side of the Beck threads 12 is fed. Instead of the operating mode caused by this modified construction, the device of Pig.5 can also work according to the description given in connection with Pig.4 and the product can be finished in a similar manner. A forwardly inclined inclined surface 44 can be formed on the rear 24 so that, as soon as the already quilted part of the endless product approaches the sewing machine head 36, the sewn-in bands run up against the surface 44 and lift the pelvic threads out of the grooves 26 so that the product can be advanced until * a is completely quilted.

In addition to the advantages that also apply to the textile product produced with the device of FIG. 4, the endless belt produced in this way has a further advantage over woven belts.

With regard to the above criteria, the example. of a filter material can be considered. More precisely, it is a filter material for filtering the waste water from a paper mill. In such filters, the aim is to remove as many solids as possible, but as large as possible To process the amount of water. For example, in the Operating such a mill has 50,000 gallons of sewage filtered per minute, with about 100 tons of solid © are removed per day.

At the same time, the filter material according to the invention left only about 0.05 to 0.06 Pfucfl. Pass (22.7-27.6 g) pests on 1,000 gallons (3.8 a ^; ) of filtrate. That.

The improvement in air filter properties lies due to both the increased permeability and the smaller pore size. i) This is partly due to fine lan ^ e Filler hair causes. The finer pas allow namely a larger total permeability (and thus permeability), but on the other hand make the individual pores smaller. That is why the filter lets more water through and keeps smaller ones glow steadily.
