Definitions
- the invention relates to a yarn which consists of at least one textile thread which contains metal fibers and other fibers, for example man-made fibers, and to the production and use of this yarn.
- a yarn For the production of a fabric for shielding electromagnetic radiation, a yarn has been proposed that consists of steel fibers, polyester fibers and polyamide fibers that are spun into a textile thread that either forms the thread itself or from which several such textile thread forms a thread are twisted.
- the steel fibers, the polyester fibers and the polyamide fibers are on average evenly distributed over the cross section of the textile thread.
- the exposed steel fibers also have disadvantages towards the outside, that is to say on the side facing away from the wearer's skin, in particular to the extent that touching a piece of clothing made from this fabric is unpleasant from the outside and the steel fibers are pulled over it Garments are disadvantageous since they cause such garments, etc. to be subjected to high stress.
- the object of the invention is in particular to provide a yarn which has the advantages of the above-mentioned yarn made of steel fibers, polyester fibers and polyamide fibers, namely enables shielding of electromagnetic fields, but which does not have the disadvantages of the above yarn, has the advantage that a fabric, knitted fabric or knitted fabric made therefrom is easily tolerable both on the side thereof which faces the skin of a wearer and on the side facing away from the skin of the wearer, can be predetermined and neatly dyed and, overall, offers the user a high level of wearing comfort and is gentle on overlying fabrics, knitted fabrics or knitted fabrics which are produced in the customary manner and are easy to maintain or wash.
- the inner cross-sectional area has the property that it shields electromagnetic radiation because of its content of metal fibers
- the outer cross-sectional area has the property that it is a woven fabric, knitted fabric made of the yarn or makes knitted fabric skin-friendly and gives this fabric, knitted fabric or knitted fabric to the outside the advantageous properties of conventional textiles, in particular it can be dyed in a predictable and clean manner and can be easily cleaned, for example in a washing machine, in which the sheathing outer Cross-sectional area forms a skin-compatible covering of the metal fibers to the outside and prevents the metal fibers from acting adversely to the outside.
- the invention is intended to provide a use of the yarn according to the invention which has the advantages of this yarn, as mentioned above.
- a textile thread is used as the yarn or twisted in the yarn, which has an inner cross-sectional area and an outer cross-sectional area encasing it, which have the properties specified under (a) and (b) above.
- the inner cross-sectional area consists of a continuous filament or thread which is spirally encased by fiber strands of the outer cross-sectional area.
- the filament or thread is intended to impart a high longitudinal tensile strength to the yarn, and the outer cross-sectional area, when using this Corespun yarn as a sewing thread, serves to shield the heat-sensitive thread against the heat generated in the thread during the machine sewing process.
- the invention differs fundamentally both in terms of the underlying task and in terms of the solution from a Corespun yarn, because in the yarn according to the invention a high longitudinal tensile strength is neither produced by the inner cross-sectional area, nor is the outer cross-sectional area used to shield the inner cross-sectional area from disadvantageous or destructive effects from the outside.
- the textile thread obtained with the invention can either be used directly as a yarn for the production of fabrics, knitted fabrics or knitted fabrics or it can be used with
- the yarn obtained in any case is processed into a woven, knitted or knitted fabric can, which is physiologically compatible and easy to process, easy to carry and maintain and which shields electromagnetic radiation in a wide frequency and intensity range.
- the outer cross-sectional area of the textile thread encasing the inner cross-sectional area can consist "predominantly" of skin-compatible fibers, in particular natural and / or chemical fibers, this means in particular the case that some of the Metal fibers that are "anchored” in the inner cross-sectional area "protrude” into the outer cross-sectional area.
- no metal fibers are used in producing the outer cross-sectional area encasing the inner cross-sectional area, although the invention is not intended to rule out the use of a small amount of metal fibers in the production of the outer cross-sectional area.
- the yarn according to the invention can be designed such that the inner cross-sectional area of the textile thread consists exclusively of metal fibers.
- Another embodiment of the yarn according to the invention is characterized in that the inner - -
- Cross-sectional area of the textile thread both from metal fibers and from other fibers, i.e. non-metallic fibers, especially chemical and / or natural fibers
- the yarn according to the invention can be designed such that the inner cross-sectional area of the textile thread consists of metal fibers and sweat absorbing or absorbing fibers, in particular sweat absorbing or absorbing chemical fibers.
- the yarn according to the invention can have one of the following two structures, of which the first-mentioned structure is particularly advantageous for manufacturing reasons, which will be discussed in more detail below:
- the structure of the yarn according to the invention can be such that the inner cross-sectional area of the textile thread consists of a fiber bundle or bandage of metal fibers that is not processed into yarn or twine. sern alone or of metal fibers, to which other fibers, in particular chemical and / or natural fibers, are added, and that the skin-compatible fibers, in particular skin-compatible natural and / or chemical fibers, which envelop the fiber bundle or the fiber structure, together with the Fiber bundles or bandages are processed into a yarn.
- the structure of the yarn according to the invention can, however, also be such that the inner cross-sectional area of the textile thread made of a yarn or twist made of metal fibers alone or made of metal fibers, which other fibers, in particular chemical and / or natural fibers, assist there is which inner cross-sectional area is covered by skin-compatible fibers, in particular skin-compatible natural and / or chemical fibers, which are spun with the yarn forming the inner cross-sectional area to form the textile thread.
- the yarn according to the invention receives the first of these two structures, it can be produced in an extremely advantageous manner in a single operation, in which the fiber bundle not processed into yarn or twine or the fiber assembly not processed into yarn or twist, the or which is made from metal fibers alone or from metal fibers to which other fibers, in particular chemical and / or natural fibers, are added, with the skin-compatible fibers, in particular skin-compatible natural and / or chemical fibers, coated and processed into the desired yarn.
- This particular method according to the invention enables the yarn to be produced very cheaply in terms of the manufacturing effort and thus the manufacturing costs of the invention, at the same time achieving a particularly firm connection between the inner cross-sectional area and the outer cross-sectional area enveloping it.
- the yarn according to the invention can also be produced in two basic operations, in that in the first operation a yarn or twine is formed from metal fibers alone or from metal fibers to which other fibers, in particular chemical and / or natural fibers, are added and, in a second operation, the yarn or thread thus produced is coated and spun with skin-compatible fibers, in particular skin-compatible natural and / or chemical fibers.
- This method is particularly advantageous if the fibers forming the outer cross-sectional area, with which the yarn forming the inner cross-sectional area or the twine forming the inner cross-sectional area is spun, laterally during spinning, in particular essentially parallel to the yarn. or twisted yarn is sprinkled on and the whole is given a torsion, that is to say, in contrast to the production of a corespun yarn, no bundle of fibers or yarn or twine is wound around, as is done in the corespun process when the filament or threading is wrapped. _,
- steel fibers made of stainless steel are preferably used in the yarn according to the invention and in its production by the method according to the invention and its use as metal fibers
- those made of other metals for example aluminum, aluminum alloys, copper, copper alloys or the like, can also be used as metal fibers. be used. - d -
- All skin-compatible textile fibers can be used as skin-compatible fibers, cotton fibers being particularly preferred as skin-compatible fibers because of their particularly good skin compatibility and cleanability, for example in washing machines, and / or wool fibers.
- the skin-compatible fibers can also be a mixture of natural fibers and chemical fibers, for example a mixture of cotton fibers and polyester fibers.
- flame-retardant and / or thermostable fibers such as aramid fibers, as skin-compatible fibers.
- FIG. 1 schematically shows a textile thread 1 according to the invention, the inner cross-sectional area 2 of which consists of metal fibers or contains metal fibers, while the outer cross-sectional area 3 has been produced by the inner cross-sectional area 2 being made using skin-compatible fibers, preferably only by means of skin-compatible fibers.
- Fabrics, knitted fabrics or knitted fabrics made from the yarn according to the invention can be used for protective clothing wherever electromagnetic. Radiation of such intensity and in such a very wide frequency range is present that health problems arise which make the wearing of such protective clothing necessary or advantageous.
- pacemakers can be inhibited by electromagnetic fields and microwave rays, ie their frequency can be influenced or even brought to a standstill - -
- Material woven, knitted or knitted from the yarn according to the invention can be used for protective clothing of all kinds against electromagnetic radiation or interference, in particular for protective suits, overalls, two-piece suits, jackets, shirts, pullovers, hoods, gloves, shoes or the like for military, industrial, medical and / or personal or private purposes.
- Such protective clothing items can in particular be shirts, pullovers, T-shirts or other upper body clothing items for pacemaker wearers.
- These protective clothing items can be used within a very wide frequency spectrum and within a very wide power density range. In particular, but by no means exclusively, protection in the HF, UHF, VHF and microwave frequency range is achieved.
