  • the present invention relates to a fabric made from interwoven threads which is suitable for use in automobile applications, in particular as a fabric cover in automobile seats.
  • the invention relates to fabrics for use in automobile seats (in particular for the surfaces which come into contact with the vehicle occupants) and to automobile seats which contain the fabrics according to the invention.
  • fabrics are subject to strong mechanical stress over many years of use, but may show as little wear as possible. Wear is caused in particular by chafing and pilling.
  • the seating comfort can be noticeably increased through the use of fibers with good moisture absorption capacity.
  • Cellulosic fibers and wool would be particularly suitable for this, but these usually have a significantly reduced rub resistance and increased pilling compared to synthetic fibers.
  • Car seat fabrics currently consist mainly of synthetic fibers and mainly 100% polyester fibers (yarn dyed / spun-dyed) or a mixture with wool.
  • polyester fibers polyester fibers
  • inexpensive filament yarn is predominantly used, with a high-priced worsted yarn being used in a mixture with wool.
  • High demands placed on car seat fabrics by German OEMs in particular include high abrasion resistance, no occurrence of pilling and fastness to rubbing, especially fastness to wet rubbing. Since the emissions scandal and the increasing production of electric cars, the argument of sustainability has become more and more important for the automotive industry.
  • recycled polyester with or without wool is used for the production of car seat fabrics.
  • the object of the present invention is to provide a fabric which can be used in particular as a car seat fabric, in which at least part of the currently used polyester fiber materials is replaced by cellulosic fibers.
  • the invention relates to the use of the fabric according to the invention in automotive applications, a method for determining whether a fabric or the yarns contained therein is suitable for automotive applications, and a method for producing a fabric which includes the step of checking whether the fabric or The yarns contained therein are suitable for automotive applications.
  • the fabric according to the invention consists of twisted threads (warp and weft threads) interwoven in a manner known per se, the twisted threads in turn each consisting of two threads twisted together, which contain fibers.
  • the fabrics according to the invention contain at least a certain proportion of yarns which contain cellulosic staple fibers of the types Lyocell (hereinafter: “Lyocell fibers”) and / or of the types viscose (hereinafter: “Viscose fibers”) and / or modal (hereinafter “modal fibers”).
  • Lyocell fibers cellulosic staple fibers of the types Lyocell
  • Viscose fibers types viscose
  • modal fibers hereinafter “modal fibers”
  • Lyocell fibers are cellulose fibers that are obtained by spinning solutions of cellulose without derivatization.
  • Viscose and modal fibers are fibers that are obtained by spinning a cellulose derivative (cellulose xanthogenate) and, in the case of modal fibers, are also characterized by certain textile parameters.
  • At least one of the yarns twisted together to form a twisted thread contains a mixture of polyester fibers and the cellulosic staple fibers mentioned.
  • the cellulosic staple fibers in the yarn are preferably either only lyocell fibers or only modal fibers or only viscose fibers. However, mixtures are also possible.
  • Lyocell fibers or modal fibers or mixtures of lyocell fibers and modal fibers are preferably used as cellulosic staple fibers.
  • different yarns can be used in a fabric according to the invention, which yarns have different compositions, both with regard to the type of cellulosic staple fibers contained and their mixing ratio with the polyester staple fibers.
  • the proportion of cellulosic staple fibers in the fabric according to the invention is 10% by weight or more, preferably 20% by weight or more, particularly preferably 30% by weight or more.
  • the upper limit of the proportion of cellulosic staple fibers in the fabric can be up to 90% by weight, in particular up to 70% by weight, preferably up to 60% by weight, particularly preferably up to 50% by weight.

  • the value for type of fiber Cell 1.2 (1 * 0.8 + 2 * 0.2) Titer Cell Single fiber titer of the cellulose staple fibers contained in [dtex], for mixtures of lyocell and viscose and / or modal depending on the weight percentage.
  • the automotive industry usually requires a chafing score of at least 3 with a number of chafing cycles of 35,000 to 60,000, in particular 50,000 to 60,000, and a print run pressure of 12 kPa.
  • the abrasion rating is given as a measure of the discoloration / graying of the sample according to ISO 105-A02 on a scale from 1 (worst value) to 5 (best value). From a value of 3, the fabric can be considered suitable for use in automobile seats. The requirement can vary depending on the positioning of the fabric in the automobile seat (e.g. side panels compared to the center panel), which is reflected either in a lower requirement for the abrasion mark or a lower number of abrasion cycles.
  • the automotive industry demands a certain (low) degree of damage to the fabric after the end of the abrasion test (i.e. after a number of abrasions of 35,000 to 60,000, in particular 50,000 to 60,000). If two (or more) thread breaks appear at the scuffed point upon visual inspection, the fabric is considered unsuitable for use in car seats.
  • the fabric according to the invention fulfills the two formulas a) and b) above, it also achieves a chafe rating of at least 3 and the desired (low) degree of damage for a given number of chafing cycles.
  • the titer Cell is preferably 0.9 dtex, particularly preferably 1.25 dtex.
  • the cut length of the contained cellulosic staple fiber cut length Cell is preferably 34 mm, particularly preferably 38 mm.

  • twist coefficient G ⁇ of those yarns which contain cellulosic staple fibers is preferably 90-135, in particular 110-135
  • the weight per unit area of the fabric according to the invention can preferably be 180-500 [g / m 2 ].
  • the cellulosic staple fibers contained in a fabric according to the invention can be dyed, in particular spun-dyed.
  • spin dyeing to be the admixture of a dye into the spinning solution from which the fiber is spun, or into a precursor thereof. This creates fibers that are not only colored on the surface, but also through their fiber matrix.
  • Another preferred embodiment of the fabric according to the invention is characterized in that some of the threads contain a polyester filament yarn or consist of polyester filament yarns.
  • polyester filament yarns does not play a role in the suitability of the fabrics according to the invention in automobile seats.
  • Another preferred embodiment of the fabric according to the invention is characterized in that the fabric, in addition to polyester staple fibers, lyocell staple fibers, Viscose staple fibers and / or modal staple fibers and possibly polyester filament yarns contain no further textile fiber materials.
  • Another aspect of the present invention relates to the use of a fabric according to the invention in automobile applications, in particular as a fabric cover in automobile seats.
  • the fabric is suitable for use in automobiles, in particular in automobile seats.
  • the lower limits can be selected by a person skilled in the art depending on the specifications given by the customer (automobile manufacturer). If, for example, the customer considers a slightly lower abrasion score (e.g. 3) or the achievement of a certain abrasion score with a lower number of abrasion cycles (e.g. 35,000) to be sufficient for a certain application, the lower limit of the value for the expression a 'can be in the lower range (ab 100,000).
  • the person skilled in the art can thus determine in the course of the production of a fabric on the basis of the parameters of the yarns, twisted threads and the fabric that are planned, whether a suitable fabric can be produced with them. If this is not the case because the desired values (right-hand side of the formula) are not met, the person skilled in the art can change one or more parameters accordingly.
  • Yarns were made from polyester staple fibers and lyocell staple fibers as well as spun-dyed modal staple fibers. Every two of these yarns were twisted into one thread, and the resulting threads were woven together into one fabric.
  • the (weight) ratio of cellulosic staple fibers to polyester staple fibers in the yarns was in each case 30 to 70.
  • the resulting fabrics were subjected to a Martindale scouring test.
  • the number of abrasion cycles was 50,000 revolutions in each case, with the exception of those fabrics, the cellulose fibers, which had a cut length of 75 mm. With these fabrics the number of abrasion revolutions was 60,000 revolutions.
  • Table 1 lists the parameters relevant to formula a), the value resulting when inserted into the left-hand part of formula a), and the chafing score actually obtained.
  • Table 2 lists the parameters relevant for formula b), the value resulting when inserted into the left-hand part of formula b) and the result of the actual assessment of the degree of damage ("0" for "no damage", ie less than 2 Thread breaks at the rubbed point, "1" for "damage”, i.e. 2 or more thread breaks at the rubbed point): Table 1: Example no.
