Abstract

Material comprises (a) textile fibres and glass fibres and (b) monofilaments or tapes made of a high mol.wt. crystalline polyester which exhibits plastic and adhesive properties at a temp. of ca. 55 deg.C. The crystalline polyester pref. has a mol. wt. of at least 5000 and is pref. extruded from a mass contg. a silica-based viscosity modifier. The material is pref. coated on at least one side with a film of crystalline polyester with a mol. wt. of at least 5000 contg. a silica-based viscosity modifier, esp. in a film 50-500 microns thick. Used in the prodn. of decorative, covering and protective materials, vessels and containers, tubes, boats, surfboards, cable protectors, etc., and esp. as splint materials to replace plaster and plaster casts for medical applications such as orthopedics, or as selvage materials. The crystalline polymer can easily be formed into the desired monofilaments, tapes, etc., by extrusion and the final material can be shaped (e.g. by immersion in hot water) at relatively low temps. of 55 deg.C., so that the bare hands can be used.

Description


  This invention relates to a thermoplastic textile material which exhibits curing properties at room temperature.

  
The object of the invention is to prescribe a thermoplastic material which can find many applications, but the properties of which will mainly be explained in the following description as a substitute for so-called plasters or plaster mesh.

  
Among the many applications can be mentioned: decorative, covering or protective material. As a protective material, it is mainly thought of vessels, containers, pipes and the like. elements. Also as a moisture protector for cables, wood, textiles and the like. the thermoplastic textile material according to the invention is eligible. Finally, the textile material according to the invention can also be used excellently for repairing elements made of plastic, such as polyester boats or polyester surfboards.

  
Notwithstanding these many uses, the thermoplastic textile material of the invention will be mainly described herein in its new and original applications for splint manufacturing replacing plaster and plaster mesh in orthopedics and occupational therapy as well as for applying so-called medical tapes.

  
In order to make this possible according to the invention, the thermoplastic textile material according to the invention is composed on the one hand of textile fibers and glass fibers and on the other hand of monofilaments or tapes which exhibit plastic and adhesive properties.

  
 <EMI ID = 1.1>

  
filaments and ribbons of crystalline high molecular weight polyester.

  
According to the invention, the crystalline polyester referred to above always has a molecular weight

  
 <EMI ID = 2.1>

  
fact that crystalline polyester referred to above is extruded from a mass containing a silica-based viscosity modifier.

processed.

  
The invention also relates to a selvedge to be used in combination with a thermoplastic material having the above-mentioned properties, which selvedge is formed by a band of crystalline polyester with a molecular weight of at least 5000, to which a viscosity modifier based on silica has been added. which band has a longitudinal fold line.

  
Finally, the invention also has

refers to one in itself. monofilament to be used formed by a crystalline polyester with a molecular weight of at least 5000.

  
The thermoplastic textile material according to the invention can have any texture, this means that it can be in the form of fabric, knitwear or it can also be produced by a technique that does not rely on weaving or knitting.

  
In order to bring the thermoplastic textile material according to the invention to the temperature suitable for processing, the material can be processed with warm water or warm air. Due to the presence in the crystalline high molecular weight polyester from which the monofilaments, the straps, the film and the self-use tapes of a viscosity modifier based on silica, the thermoplastic material does not stick to the hands or objects with which the thermoplastic textile material can be processed.

  
When the thermoplastic textile material according to the invention is used in orthopedics, for example for applying splints or analogous bandages, the bandage can be deformed again after a certain time by using warm air or warm water if necessary. structural dimensions are changed. This represents a very great advantage over the products currently used and known as plaster casts.

  
A great advantage of the material according to the invention is to be seen in the fact that monofilaments, selvedge and the thin film by extrusion ./.

  
can be achieved so that these products can be produced with the necessary cross sections.

  
Another advantage of the material according to the invention is that the plastic thus becomes thermoplastic deformable from 55 [deg.] C so that it can be processed with bare hands.

  
A very striking advantage of the textile material (monofilament, selvedge and film) is that it becomes translucent at 55 [deg.] C, so that the underlying layers can be seen during processing. Thanks to this property, the material itself indicates its condition, i.e. when the product is white and opaque, the product is stiff (at a temperature

  
 <EMI ID = 5.1>

  
apparently this is an indication that the product is deformable.

  
 <EMI ID = 6.1>

  
product is very soft and stretchable so that it can take any shape while clinging to any surface during hardening.

  
It should also be noted that
55 [deg.] C the product is stretchable in all directions to a great length. As mentioned above, the product has a so-called "elasticity memory", which means when heated. for example in water or by warm air it can always take on its original form.

  
Finally, it should be noted that the material is self-adhesive both to itself, even in the wet state, and to other materials when heated to more than 100 [deg.] C. However, this clamping does not occur when the materials to which the thermoplastic textile material according to the invention is applied are cool unless the cool materials are of the fibrous type as is the case for textile cloth.

  
Other advantages of the material are that it can harden very quickly if desired; that it can be heated and deformed an infinite number of times; that it has a smooth finish, can be easily cleaned with water and / or soap; that it is in case of medical application

  
 <EMI ID = 7.1>

  
which is also important when the material is kneaded and processed with bare hands; that it is odorless and is not affected by UV rays or liquids, such as oil and the like.

  
The thermoplastic material according to the invention is very strong, rigid and rigid, but always locally deformable with the use of warm water or warm air. It is advantageous that the product according to the invention shrinks by 2%, which is important in the case of a close connection, for example when covering curves.

  
 <EMI ID = 8.1>

  
In certain embodiments, the thermoplastic material may be combined with a foam layer.

  
The composition of the invention based on a high molecular weight crystalline polyester incorporating a silica viscosity modifier is excellent as a medical suture wire and as a welding wire. The adhesive properties of the thermoplastic textile material according to the invention depend on the amount of monofilament or film in the product itself. Preferably the addition of monofilament in the product will be included between 25 and 75% by weight, the adhesive strength of the thermoplastic textile material according to the invention at a temperature above 55 [deg.] C by itself and at

  
 <EMI ID = 9.1>

  
than at a lower addition.

  
The product of the invention covered with a film of the same crystalline high molecular weight polyester has a thickness corresponding to

  
 <EMI ID = 10.1>

  
the same thermoplastic material that is used as a selvedge for finishing a dressing, for example, is 10 to 30 mm wide. The band has one in the middle

  
 <EMI ID = 11.1>

  
centerline can be folded. After the tape has been heated in the usual manner and at the required temperature, the tape can be kneaded at this temperature and processed with the actual textile material.

  
It is clear that the invention is not limited to the above-described embodiment and that many changes can be made to it both as regards the structural appearance of the thermoplastic textile material according to the invention and the intended applications thereof.
