Definitions

  • the invention relates to a method according to the preamble of claim 1, and textile goods produced by this method.
  • the goods are either made from an elastomeric material and / or from highly textured yarns, in particular polyamide yarns, which have a corresponding additional elasticity due to the texturing.
  • textile goods made from synthetic yarns cannot be worn by a large group of people and they have disadvantageous properties, in particular a relatively low level of thermal insulation and absorbency. It is therefore known to produce textile goods from blended yarns which e.g. Textured bolyamide yarn with wool or cotton included. The goods themselves can also be made from synthetic threads and natural fiber threads.
  • synthetic fibers have the poor wearing properties described above.
  • the wearing of tights or other items of laundry made of such synthetic fibers therefore leads to glue to the skin in summer due to low absorbency, while in winter only a low level of heat protection is achieved.
  • many people are allergic to the wearing of synthetic fibers.
  • a method for producing elastic bandages for medical purposes in which all warp threads made of natural fibers are woven with a strong twist in one direction with weft threads made of soft, resilient, non-woven natural fiber material. As a result, the warp threads partially turn back in the finished fabric and take a zigzag or. corrugated position so that the bandage is elastic in the warp direction.
  • the effect used here is opposite to the effect according to the invention, in which the twisting of the yarns is to be prevented.
  • the strong Fixing the high-freehole position and turning the yarn back to close to the starting twist position or yarns formed in addition with strong reverse twisting force can either be incorporated adjacent in the textile goods, for example ' with opposite reverse twisting force as adjacent warp and / or weft threads in a fabric or in successive courses of a knitted fabric, or it is possible to produce combined threads in which two yarns are twisted together in such a way that the strong reversing forces which result from the fixing of the high rotation position and the subsequent turning back or the resulting return forces in the longitudinal direction of the yarns act against one another, or also through contact of such a yarn are supported on correspondingly strong support threads, for example of appropriate elastomers.
  • the textile goods produced according to the invention can be damped after production in a manner known per se for relaxing the yarn, as a result of which the yarns shrink and the resilience is increased after elastic stretching.
  • the yarn or the thread can be turned up to close to the critical pivot point.
  • the critical pivot point is the degree of twisting at which the increase in the strength of the yarn twist due to the increase in the frictional pressure has a certain saturation limit depending on the spinning structure (adherence and pliability) and deformability of the fibers. If the critical pivot point is exceeded, the thread is twisted off.
  • the yarn can achieve the required return torque and thus the required return force in the longitudinal direction beyond the initial turning state to the zero point or beyond be rotated.
  • the initial twist state denotes the twist of the yarn in which the fibers are in the same relative position to one another as in the case of the starting yarn before twisting.
  • the zero point denotes the rotational position of the yarn at which the fibers are approximately parallel to one another, ie at which the yarn has no twist at all.
  • the turning up and / or turning back can take place on ring twisting machines, with the yarn generally being wound up or wound up after each operation, or the turning up and turning back can be done on a false twisted wire machine, friction texturing machine or the like. respectively.
  • this false twist or friction texturing machine the thread is turned up in one pass in one pass and, after being fixed, turned back in the opposite direction.
  • the yarn or the thread can be impregnated with a fixing agent before or during the turning up or in the turned up state, and the latent fixing effect of this impregnating agent can be triggered in the turned up state.
  • This impregnation of the thread can be done during the run when turning up in the machine by means of a Impregnation tub take place, or it can be done before turning up or after turning up if the yarn is in strands or on bobbins. All known agents can be used as impregnating agents for the corresponding fibers, which are used in such natural fibers for a corresponding fixation of a specific layer.
  • the impregnating agent for fixing the yarn can contain a means for splitting the bifunctional and / or polyfunctional bodies of the fibers and for permanently fixing them in the new position.
  • a reactant resin dimethyl-diethylene urea or a mixture of these can be used to impregnate yarns or twists and cellulose fibers.
  • Chemical products of the type known for the iron-free finishing of cotton fabrics can also be used for the fixation of cotton yarns according to the invention.
  • agents can be used which are known for the crease-free finishing and stabilization of wool fabrics, while chemical products can also be used for protein-containing fibers, such as wool and silk, as are known for the permanent shaping of human hair during the perm.
  • a temporarily higher temperature than the known one can be used to trigger the latent fixing action.
  • silk or wool yarns can be fixed by heat treatment at a temperature of over 220 ° C.
  • a preparation can be applied to the thread before it is fixed, which prevents static charging and / or improves the sliding properties.
  • An aqueous emulsion of polysiloxanes and additives to reduce the static charge on the thread can be used as a preparation.
  • textile goods used here includes all fabrics, knitted fabrics, knitted or other webs, ribbons, garments or the like produced by connecting threads. a.
  • essentially inextensible warp threads e.g. made of silk, woven using weft threads 2a and 2b.
  • the weft threads 2a have a turning force in the direction of the arrows A and the warp threads 2b have an opposite reverse twisting force in the direction of the arrows B.
  • the restoring force is transmitted through the contact of the weft threads in the tissue with one another and through their connection through the essentially inextensible warp threads to the adjacent weft threads with opposite reversing force, so that the restoring forces cannot cause the threads to twist, but rather from opposite directions Reverse forces of the adjacent weft threads are absorbed.
  • Fig. 2 shows a modification of the invention, in which the reaction forces are absorbed in a thread itself.
  • 2 consists of a core thread 5, for example made of silk or wool, which, as described above, is fixed and turned back and thus has a considerable reversing force in the direction of arrow C.
  • a core thread for example made of silk or wool, which, as described above, is fixed and turned back and thus has a considerable reversing force in the direction of arrow C.
  • a highly elastic cover thread 6 made in the same way from the same or a different natural fiber material as the core thread against the direction of the return force of the core yarn 5, ie twisted in the direction of arrows C 1 , so that the elastic acting in the longitudinal direction of the cover thread 6 Return force counteracts the return force of the core thread 5.
  • the twine according to FIG.
  • the reverse twisting or resetting forces caused by the upward rotation, fixation and strong reverse twisting cancel each other out, so that the twisted thread itself has no reversing force but only a return force in its longitudinal direction.
  • 2 can be woven as warp and / or weft thread, for example in looms used for weaving elastic synthetic threads or knitted in conventional knitting machines.
  • a smooth synthetic thread can be used, the torsional resistance of which is so great that it absorbs the resilience of the cover thread acting in the longitudinal direction without substantial deformation.
  • a thread can be produced, the resilience of which is extraordinarily strong in the longitudinal direction, and in particular is particularly suitable, for example, for heavy corsetry or orthopedic support stockings, without the disadvantages of the synthetic elastomer core thread being effective, since this synthetic elastomer core thread is completely covered over its entire length by the cover thread consisting of natural fibers.
  • the longitudinal elasticity of the elastomeric thread is not impaired, since the elasticity of the cover thread is so great that it also undergoes very strong stretching of the elastomeric core thread.
  • the cover thread If known, or only very weakly elastic threads made of natural fibers are used as the cover thread, the elasticity of the elastomer core thread would be greatly restricted or the cover thread would be overstretched, so that after the elastic longitudinal stretching of the core thread was reset, it would not again lie in smooth spirals around this core thread but would form defects in the tissue.
  • a section of a knitted fabric e.g. for a pair of tights, shown in simple stitches, in which yarns consisting of natural fibers are knitted in successive rows a, b, c, d, which are alternately strongly turned up in opposite directions, fixed in the upward rotation position and turned back to near the starting rotation position or beyond are.
  • the yarns are fed to a knitting machine during knitting with successive systems rotating in opposite directions.
  • the yarn in courses a and a has a direction of rotation in the direction of arrow D
  • the yarns in courses b and d have an opposite direction of rotation, in the direction of arrows E.
  • the opposite direction of rotation of the yarn causes an opposite inclination of the stitches in the individual rows, which causes an additional elasticity of the knitted fabric.
  • this inclination of the stitches serves to achieve an increased stretch effect by counter-rotating the yarns.
  • this inclination would not be necessary per se, since the yarns made from natural fibers with a very strong reversing force themselves have an extraordinarily high elastic extensibility of up to 500%, so that even with very tightly knitted goods in which the inclination is not effective or only very slightly a very large elasticity is ensured in all directions.
  • Silk weft is about 1: 1.
  • a clothing fabric is created which has a permanent elasticity of 15-20% in the weft direction.
  • a thread made of Lycra (Dupont) or Dorlastan (Bayer) based on polyurethane is twisted with this highly elastic silk thread in such a way that the thread wraps around the polyurethane thread in various turns, so that a material ratio of 3: 1 silk / polyurethane is achieved.
  • threads are woven in a taffeta weave on a protective weaving machine manufactured by Sulzer (Switzerland).
  • a twist is used as the core thread, in which 2 natural silk threads, 50 den, treated as example 1, twisted, fixed and turned back, are twisted on a ring twisting machine with a protective twist of 70 T / m in the S direction.
  • This core thread (twisted) is twisted with a cover thread, as in Example 2, in a Z-twist.
  • the cover thread / core thread material ratio is 2: 1.
  • the elasticity is permanent even after repeated washing.
  • the starting material is Brasil-Grege in titer 78 den.
  • the titer is 50 den.
  • Impregnation, coils, texturing as example 1 with corresponding titer conversion Impregnation, coils, texturing as example 1 with corresponding titer conversion.
  • the result is a highly elastic knitted tube with high elasticity and elasticity in all directions.
  • This knitted tube is made into women's briefs that have the best fit due to their elasticity.
  • This thread strives to return to the fixed, turned-up state and contracts like a spiral spring. This results in permanent elasticity that is at least 200% in the thread.
  • these socks are washable at 30 - 35 ° C.
  • the elasticity is permanent even after frequent washing
  • the method according to the invention can also be used with the addition of synthetic fibers or yarns if this addition e.g. to achieve an increased wear resistance of the goods compared to the pure natural fiber or is desired for other reasons.
