Hcrauateeile, of which one has a low softening point al ο dio others _f by exerting heat and bridging on the fiber mixture ι so that the fibers with the lower melting point become adhesive and thereby cause the material to be bound. When producing bound textile fabrics in which potentially adhesive fibers are activated if a fiber mixture containing them is exposed to heat and pressure, these fibers need to be deformed by the pressure and if the heat is sufficient They can lose their fiber form and their identity as fibers in whole or in part. Their contribution as fibers to the strength of the material can thereby be reduced. Moreover, if the potentially adhesive fibers are homogeneous in character, it is difficult to control the temperature and pressure conditions by which the fibers are made tacky but not destroyed. Because of the possibility of such potentially tacky fibers losing their fibrous shape by melting, there is a risk that the resulting molten hate will spread through the fabric, which is often in one The dimensions are stiffened so that in certain cases it cannot be used They often have a more or less hard and uncomfortable grip and are often noticeably rough, due to the intermittent bonds that are formed throughout the material by the potentially adhesive fibers.

According to the invention, the hearing aid should be a usable and dyeable bonded Textiles with colored character are made available «° in which the binding is oraiolt through the toilet features, at least that has some of the fibers present in the material.

According to the invention, improved bonded textile fabrics are also intended β of the type mentioned are made available in which the fibers exhibiting the adhesive properties have their shape and identity retained as fibers during and after activation, which cause the adhesive properties to be generated.

Appropriate procedures and instructions for use in the manufacture of heterof & those by melt spinning where the components lie side by side, and for example in the same-sided Anbünglgon applications 27350/61 and 29295/62 described by the applicant. Before or during the spinning process, pigments, softeners, dyes, Hottensohutzstoffe, Fire retardants, fillers, abrasives and / or light stabilizers to be added. Especially if the potentially adhesive Component can be activated by heat, it may be desirable to stick to the spinning solution or in some other way Component of the heterofode to add suitable substances, duroh which lowers the softening point of the component, 8.B. Plasticizers, white resin and the like. Suitable plasticizers for this purpose are dibutyl tartrate, xthyl phthallate and xthyl glycollate.

It is not a necessary feature of the invention that the heterofilaments have such potential crimp when also in the manufacture of certain bonded textiles of the invention it is sometimes found pleasant, the curling ability to use such threads while relaxing to obtain a material that has a fuller and warmer feel. Under In such circumstances it is necessary that the crimp is produced before the fiber structure is activated.

So can be used in the production of a woven or knitted Fabric the hetero threads either alone or in Uisohung with Nioht activatable fibers carded and then a pull and To be subjected to spinning, cut out a yarn. The yarn can be activated after weaving or knitting under pressure. This treatment is not only used to change the structure of the yarn to stabilize in the woven or knitted fabric! but also the structure of the fabric as a whole thanks to the adhesion of the threads to stabilize at the crossing points of weft and warp or of loops in the knitted fabric. A separate activation can be carried out in a simple manner that the woven or knitted structure is passed between the gap of a heated pair of rollers or that they are avisched heated plates is pressed. In fons of continuous The prayer threads can be threaded with a potentially clunkable Component duroh subjects to be processed into cords, after which the individual compartments are bound by heating under pressure

Raise the mixing thread relatively short length, such as staple fibers in the above-considered manner, the yarns can be formed from continuous filaments "of which some or all" Straight threads, and such yarns can au woven or knitted or substances from twisted yarns in the same catfish can be processed like a staple fiber yarn.

Knitted fabrics, for example, are free of any warping and run noses when one of the knitted loops travels. Before a bulky type of knitted or woven fabric is required, the yarns from which the fiber structure is built can consist of heteroffts or contain hetero threads "τοη at least a part of which has a potential crimp" The crimp in the hetero threads is then caused by this »That the fiber structure is treated under relaxed conditions, and the resulting bulky structure is then activated by heating under pressure.

Yarns which consist of or contain hetero threads »and continuous hetero threads can be used in the production of laid or woven coarse fabrics, for example werdon used in the manufacture of plastic panels .. The use of hetero threads in the manufacture of Coarse fabrics simplify their production considerably. E.g. The binding of the laid or woven structure can be carried out simply by using VHxme and Druok, and thus 1st Need to use a heat sensitive warp size or for dipping the structure in an adhesive prior to binding it to da.i weave tree.

As examples of some of these applications. can be purchased here Industrieetoffe sur IBrme-, Soball- and sheet metal insulation, as a floor covering, in the case of filtration of Gases and liquids, as heat substances, in the manufacture of hats, caps, jackets and other clothing and all Zwieohenlagen for Anatige und.MBntel and ale Hauehaltestoffe, and for a variety of upholstered awake tokens · .You can also al · base are used »to which many OberBugatoffe are applied can, un panels or geforate fabrics have improved properties to build·

Examples are explained, which the scope of the invention should not restrict.

Example 1

A quantity of a 4om staple fiber with a denier value of 12 _f, which was obtained from the oriented polyhexamethylene adipamld / poly (omega-iminoiuideoanon8äure) -HeterDfftden (Hylon 66/11), in which the two components were present in the same weight ratio and side by side, was used in a loose fiber tape was carded, which was then brought to avischen bebelxte plates, which were kept at 210 ° - 220 ° C and subjected to a pressure of 700 gn / oa for 15 seconds Handle, was free of drips and possessed considerable strength. A mixture of equal parts by weight of 4 ca staple fibers ddt a denier of 6 from folyhexamethylene adiparid and PelyConega-aminoundeoanonic acid) was carded on a loose strand, identical to that formed with the hetero threads and was subjected to the same binding treatment. The non-woven fabric formed from this sliver had a hard and coarse handle and was noticeably rough because of the tauthandensoins of many drops due to the deformation of the poly (omega-aminoundeoanoneaure) fibers.The strength of both fabrics was determined in a new Instron tensile tester , in which a 5 * 08 cm (2 solos) wide sample is placed between the Baoken de 3 instruments, which were 5 em apart, and the

The sample was passed at a rate of 10 om / min., Ie 200 μl per minute, at a temperature of 21 ° C. and a relative humidity of 60 ° . The strength and other physical properties of the two substances are summarized in the following table
