Definitions

  • the present invention relates to a fine knit for the production of clothing, which can be disposed of in an environmentally friendly manner.
  • fine knitwear for garments has been made in many cases from non-rotting polyamide which is insoluble in water up to high temperatures.
  • Polyamides of the current application forms are not harmful to the environment, but they are also not easily biodegradable and accordingly belong to the residual waste, which usually has to be incinerated or landfilled.
  • Such fine knitted fabrics can be washed repeatedly and can be worn many times, worn or damaged clothing items create an additional amount of residual waste, which should be avoided or at least reduced in the course of increased environmental awareness among the population.
  • the object of the present invention is to maintain a fine knit while maintaining the positive properties of polyamide in this regard.
  • this object is achieved by a fine knit according to claim 1.
  • Advantageous embodiments of this fine knit are specified in the dependent claims. If you use a material for the production of a fine knit that is dimensionally stable at temperatures below 95 ° C and insoluble in aqueous solution, even in slightly basic or acidic aqueous solution, then this material fulfills the primary requirements for the production of garments of human skin. Of course, this material must not be attacked by sweat and / or personal care products, so that it should be stable in the temperature range up to 45 ° C even at pH values of 6 to 8, especially even from 4 to 10 in aqueous solution.
  • the material In order to be suitable for the production of a fine knit for garments, however, the material must be able to be textured in order to achieve sufficient elasticity and to ensure the fit of garments. Threads are usually textured by treating them in a false twister at high temperature, which gives them a certain surface roughness and elasticity.
  • another property of the material namely its complete solubility in water, e.g. B. at temperatures above 95 ° C, preferably above 110 ° C, in particular between 110 ° C and 150 ° C. This property makes it possible to dissolve a worn or damaged fine knit in hot water and dispose of it with the waste water. This can be done, for example, in a pressure vessel in which large quantities of fine knitted fabrics can be disposed of relatively inexpensively.
  • thermodegradable and water-soluble threads have led in particular to biodegradable and water-soluble threads, although there is now a very wide range of variation with regard to the temperatures at which water solubility occurs.
  • hot-melt adhesive fibers e.g. B. polyamides or materials known as alginates, which are produced from naturally occurring precursors.
  • Other synthetically manufactured products with the desired properties are also available (see e.g. lecture at the 32nd international conference on chemical fibers ... in Dornbirn / A, September 22-24, 1993, "Manufacture, properties and applications of hot melt adhesive fibers "by Dr. V.

Abstract

L'invention concerne un tricot fin pouvant être éliminé de façon écologique, destiné à la fabrication d'articles d'habillement, en particulier de bas et de collants fins, composé de fils texturés d'un matériau hydrosoluble présentant les propriétés suivantes: stabilité dimensionnelle à des températures inférieures à 95 °C; insolubilité à des températures inférieures à 45 °C, de préférence inférieures à 95 °C, dans des solutions aqueuses légèrement basiques ou acides présentant un pH compris entre 6 et 8, en particulier entre 4 et 10; solubilité totale dans l'eau, par exemple à des températures supérieures à 95 °C, de préférence supérieures à 110 °C, en particulier entre 110 et 150 °C; aptitude à la texturation à des températures supérieures à 95 °C, de préférence supérieures à 110 °C, en particulier entre 110 et 150 °C. Le matériau dissous dans l'eau, par exemple un copolyamide ou un alginate, peut être complètement dissous par exemple dans un récipient sous pression, et il est biodégradable ainsi que non dangereux pour les eaux. En dépit de sa grande solubilité, il peut être soumis à une texturation durable, par exemple à 120 °C, jusqu'au niveau requis pour les tricots fins, et teint par exemple à 80 °C.
