Definitions

• the invention relates to a process for the production of shaped textiles, in particular corsetry textiles, such as e.g. Bra cups (brassiere cups) using a core yarn (i.e., a yarn composed of a yarn core wound with a yarn sheath) which does not require chemical finishing of the fabrics.
• a core yarn i.e., a yarn composed of a yarn core wound with a yarn sheath
• bra cups Made of natural fiber textiles bra cups are characterized by a very high level of comfort. However, they have the disadvantage that they are not permanently deformable, that is, they can be deformed in principle, but they lose the previously imprinted shape with each washing again.
• bra cups made of natural fiber textiles
• the bra cups are either specially sewn or treated with chemical equipment (see FIG. DE 80 11 510 U1 ; chemical equipment with synthetic resin).
• chemical equipment see FIG. DE 80 11 510 U1 ; chemical equipment with synthetic resin.
• the seams of specially sewn bra cups regularly cause mechanical irritation to the skin, and the chemicals used in the bra cups provide allergic irritation to the skin.
• the yarn cores of the hitherto known yarns consist of polymers that can be deformed only at temperatures of 200 ° C and higher.
• the yarn cores of the hitherto known yarns consist of polymers that can be deformed only at temperatures of 200 ° C and higher.
• the natural fibers of the yarn sheaths would be damaged.
• more environmentally harmful substances would be released, which would cause a relatively high burden on the environment and for the people involved in the manufacturing process.
• DE 603 04 829 T2 shows a wrapped yarn in which the core yarn (ie, the yarn core) is a polyester, polyvinyl alcohol or polyamide yarn.
• the core yarn ie, the yarn core
• the coated yarn should not be particularly skin-friendly and easily deformable, but it should have excellent mechanical (and refractory) properties and produce pleasant visual sensations, tactile and olfactory sensations.
• about the softening temperature of the yarn core no statement is made.
• the invention has for its object to find a method by which skin-comfortable textiles can be produced using a core yarn, which, without this chemical equipment is required at relatively low temperatures can be shaped so that it is dimensionally stable even with frequent washing stay.
• a core yarn which consists of a yarn core which is wound with a yarn sheath, preferably in the S and Z directions.
• the yarn core is made of a non-elastic (i.e., compared to elastomers such as rubber, only relatively small elastic deformations are possible) thermoplastic material (usually in the form of fibers) which is deformable in a temperature range of 85 ° C to 180 ° C.
• the yarn coat consists of skin-friendly fibers.
• a textile is made from the core yarn in a first step, without the textile is provided with a chemical equipment.
• the textile is deformed at 85 ° C to 180 ° C so that it retains its geometry even if it is washed very often.
• the textiles produced with the core yarn according to the invention can be deformed at relatively low temperatures of 85 ° C to 180 ° C (dimensionally stable), a temperature-induced damage to the natural fibers of the yarn sheath is avoided, causing the deformed textiles u. a. stay very lightfast. It is also advantageous that in the deformation of the textiles compared to the conventional methods, only a small amount of harmful substances is formed, that is, the burden on the environment and the persons involved in the manufacturing process of the textiles is relatively low. In addition, the use of the core yarn according to the invention enables an uncomplicated and cost-effective production of shaped textiles.
• thermoplastics such as polyamides, polyesters, polyurethanes, polypropylenes or polyethylenes are preferably used for the yarn core.
• PA11, PA12 or PA hot melt adhesive yarns are particularly suitable (as materials for the yarn core).
• polyesters From the group of polyesters are correspondingly PES melt adhesive yarns, but no PET, PBT, PEN or PC fibers are to be used.
• polyurethanes whose melting points are in the temperature range from 85 ° C to 180 ° C can be used for the yarn core.
• high-quality natural fibers such as e.g. Cotton, silk or fine wool fibers. But it can also be used viscose or modal.
