Definitions

  • the invention relates to a method of the type corresponding to the preamble of claim I and a system of the type corresponding to the preamble of claim 21.
  • High-quality finishing Equipment for permanent improvement of the usability of cellulosic or cellulosic and also other, but similarly acting textile materials is referred to as high-quality finishing.
  • the properties of the textile webs are improved by embedding high finishing agents in the fibers or by modifying the fibers with the help of the high finishing agents.
  • the crease resistance, the shrinkage stability, the wash-and-wear behavior, the water-repellent behavior, the permanence of pleated and calendering equipment (embossing / chintz / corrugated effects) and the like are improved.
  • a disadvantage of high-quality finishing is that it is accompanied by a noticeable reduction in the mechanical properties of the textile webs, such as abrasion and tear resistance. It is therefore important to achieve the finishing effects with as little loss of mechanical properties as possible.
  • the finishing agents are mostly water-soluble, low-molecular polyfunctional products which, in the presence of acidic or alkaline-acting finishing agents, Catalysts water-soluble and solvent-insoluble and thus washable and dry-cleanable high molecular weight compounds are transferred and / or crosslinked with the cellulose fiber.
  • Important examples of high-quality finishing agents are acid-crosslinked N-methylol compounds, in particular dimethyloldihydrogenethyl urea (DMDHEU), but also many other compounds.
  • DMDHEU dimethyloldihydrogenethyl urea
  • the various crosslinking processes provide characteristic differences in the properties of the finished web (fabric), which are reproduced qualitatively in the table below in comparison with one another.
  • Dry crosslinking is the cheapest, is easy to control and gives sufficient results for most requirements. Moist crosslinking allows the loss of strength to be kept within limits while the wash-and-wear behavior is still usable, albeit at high costs and poor process reliability.
  • wet crosslinking is only used for articles that are not subject to dry crease, such as bed linen, tablecloths and decorative fabrics made of cotton and linen.
  • the wet cross-linking process is increasingly being used in the areas of application predestined for this property spectrum - high-quality shirt and blouse fabrics or the like.
  • the reason for the poor dry crease angles in wet crosslinking is as follows: if swollen cellulose is crosslinked, the less dense areas lying between the fibrils of the cellulose fiber are widened to such an extent that the distances between the adjacent fibrils from the molecules of the high-quality finishing agent are not can be bridged more. For this reason there is essentially only crosslinking within the denser areas of the fibrils, so that the wet crosslinked fiber can swell again even after intermediate drying. During wet crosslinking, the glasses remain separated by flexible chain molecules, whereas in dry crosslinking they are inextricably linked to one another with a considerable reduction in the swellability of the fiber.
  • the fiber When wet cross-linked, the fiber reacts in its quasi-natural state with a water content of approximately 7%, which corresponds approximately to the equilibrium moisture. Since the tensile strength depends on the extent to which the crosslinked cellulose chains can still move under tensile load, it decreases less in the case of wet crosslinking, in which the interfibrillary areas are expanded by the swelling, than in the case of dry crosslinking. With the moisture content of the fiber still suitable for wet crosslinking, only a narrow tolerance range can be permitted, namely approx. + 1%. If the fibers dry out too much, the finishing effects of the dry crosslinking approach, whereby the strongly acidic catalyst can destroy the goods through hydrolytic degradation of the cellulose.
  • the finishing effect will tend to wet crosslinking, however due to the weak catalysis here with an insufficient refining effect.
  • the invention has for its object to further develop the generic method so that the results are improved economically and technically.
  • the set value of the moisture with which the web travels through the elongation and enters the steam atmosphere depends on the product and refinement and is in the range of 30-120% (the weight of the dry goods). 30 - 70% for cotton
  • crosslinkable fibers such as triacetate, 2 1/2 acetate, etc.
  • the liquor of the finishing agent can be applied cold, optionally followed by heating of the web, because the broad stretching with constant small area stretching is the best Effects in the temperature range of 60 to 90 C results.
  • the liquor of the high finishing agent can also be applied heated, although this heating is subject to limits so that the crosslinking does not start too early, ie before the expansion.
  • a high-quality finishing agent is a finishing agent that is reactive for cellulose (claim 4).
  • a preferred field of application of the process according to the invention is crease-resistant finishing, in particular with DMDHEU (claim 5), in which case the liquor of the high-quality finishing agent is neutral to strongly acidic (claim 6).
  • the web can be dehumidified to the defined moisture content in a first alternative after the application of the finishing agent, for example by the squeezing mechanism of a foulard or by a suction device.
  • the liquor can be applied in advance in the amount corresponding to the desired moisture content with the high finishing agent, for which there are suitable processes in the prior art, for example the various MA (minimal order) processes, for example according to DE PS 21 14 517 from Triatex International AG, Zurich (Switzerland), the foam application method or the order with a device according to DE-PS 37 33 996.

  • the values that are suitable for the elongation are approximately in the range from 1 to 10%. Which values come into consideration depends on the type of goods and the pretreatment. According to claim 13, the elongation can be controlled to a constant web width.
  • the residence in the steam atmosphere takes place in a saturated steam atmosphere at temperatures up to about 130 ° C.
  • the time spent in the steam atmosphere should be between 0.1 and 5.0 minutes (claim 15).
  • the networking in the damper results in significant simplifications in terms of environmental protection compared to the networking in the stenter, which is frequently practiced.
  • Large quantities of contaminated exhaust air are generated in the stenter frame, and a smaller quantity of contaminated steam is generated in the damper, which can be easily condensed, for example by introducing it into a downstream washing bath. In this way, the escaping gaseous crosslinking products can be kept under control more easily.
  • the material web can be post-treated in the usual way (claim 16), cooling (claim 17) and a washing process (claim 18) being particularly suitable.
