Definitions

• ammonia is present as an anhydrous liquid swelling agent which, while very concentrated, is a much weaker alkali than aqueous alkali solutions. Accordingly, there is a changed swelling of the cellulose structure and it forms a limited stable form of cellulose, which is summarized under the term cellulose III.
• the ammonia process therefore also has certain advantages in practice, the disadvantage of this process is the high design complexity of the treatment devices, which is necessary due to the ammonia to be liquefied, with respect to their tightness in connection with strictly controlled pressure and / or temperature conditions, and associated therewith , high cost of such a facility.
• DE 24 05 006 A1 discloses a variant of the hot-mercerization of cellulose textiles in which only small amounts of an alcohol are added as a wetting aid.
• a method for stabilizing cellulose fibers with the features of the independent method claim and the use of a water-binding component as an additive in a treatment solution for the stabilization of cellulose fibers.
• the process according to the invention for stabilizing cellulose fibers, in particular materials comprising essentially exclusively cellulose fibers is characterized in that the cellulose fibers are brought into contact with a treatment solution, the treatment solution comprising:
• the cellulosic fiber-containing material is substantially, preferably completely, free of regenerated cellulose based yarns and fibers
• the proportion of water binding component (a) in the processing solution is at least 10% by weight, preferably between 10% and 90% by weight, and the components (a), (b) and (c) and their proportions of treatment solution are selected so as to cause swelling of the cellulose fibers predominantly in amorphous regions.
• the cellulose fibers to be treated are particularly preferably present as a textile material web; but also the treatment of non-cellulosic cellulosic fibers, such as, for example, threads, yarns, etc., is possible within the scope of the invention.
• a water-binding component (a) the water content of the treatment solution can be varied and in particular set low, so that results are obtained which are comparable or superior to those of the anhydrous ammonia treatment.
• the water content (c) must be at least so high that results in a homogeneous solution in particular of the swelling agent (b). Despite this residual water content, however, properties of the treated fibers which surprisingly result in the properties of fibers which have undergone an ammonia treatment known from the prior art are surprisingly obtained.
• the water-binding component preferably binds part of the water of the treatment solution in a so-called hydrate layer or via hydrogen bridges, so that this water content is not attributable to the free water content.
• the free water content that is to say the proportion of the water (c) which is not bound by the water-binding component (a), can thus be set and, in particular, minimized via the selection and / or the amount of the water-binding component (a).
• the cellulosic fibers or materials comprising cellulose fibers are substantially, preferably completely, free from regenerated cellulose based yarns and fibers.
• Regenerated cellulose-based yarns and fibers are understood here to mean in particular: viscose (CV), lyocell fibers (CLY), modal (CMD), cellulose fibers (CU) produced by the copper ammonia spinning process, viscose chemisides, rayon, viscose spun silk, viscose rayon, copper chemisides, copper chemical spun fiber, modifier - or Modalfasern, (HWM) Polynosic (see M. Peter, Handbook for Textile Engineers and Textile Practitioners, Foundations of Textile Finishing, 10th Edition 1970, Dr. Spohr-Verlag, Stuttgart).
• the components (a), (b) and (c) and their proportions of the treatment solution are selected such that swelling of the cellulose fibers is effected predominantly in amorphous regions, ie in particular no significant swelling also occurs in crystalline regions which among others expressed in a stiffening of the tissue. It can be seen that the proposed method swells the cellulose fibers predominantly in amorphous areas (formation of cellulose III / IV), whereas in the mercerization in the liquid phase the swelling occurs predominantly in crystalline areas (formation of cellulose II); As a result, particularly advantageous fiber properties can be achieved according to the invention, which are comparable or even superior to those of the ammonia process.
• a water-binding component (a) used is an alcohol, in particular a polyhydric, preferably aliphatic, alcohol, more preferably selected from the group consisting of methanol, ethanol, 1-propanol, 2-propanol, 1,3 Propanediol, 1,2-propanediol, 1, 2, 3-propanetriol, 1-butanol, 2-butanol, tert-butyl alcohol, 1, 2-butanediol, 1, 3-butanediol, 1, 4-butanediol, 2, 3-butanediol and mixtures thereof.
• Such a component (a) under standard treatment conditions in the liquid phase, as described in the introductory part, in turn additionally and particularly advantageously on solvent properties, in addition to the existing water.
• water-binding component in another preferred embodiment of the invention it is used as a water-binding component.
• a solid which is selected from the group consisting of carbohydrates such as glucose, sucrose, fructose, galactose, mannose and other monosaccharides, disaccharides, oligosaccharides, their corresponding carboxylic acid derivatives such as gluconic acids, glucuronic acids; Urea, inorganic salts (especially with cations such as sodium, potassium, ammonium, magnesium, calcium, and anions such as chloride, nitrate, sulfate, phosphate, polyphosphate, silicate, and mixtures thereof); Particularly preferred inorganic salts are NaCl, KCl, MgCl 2 , Na 2 SO 4 , K 2 SO 4 , MgSO 4 , Na 3 PO 4 , K 3 PO 4 , NaNO 3 , KNO 3 , Mg
• the water-binding component (a) used is either 1,2,3-propanetriol or NaCl or mixtures thereof; these water-binding components (a) have proved to be particularly advantageous in practice because of their ease of handling, as well as their common and cost-effective availability and good to outstanding resulting fiber properties.
• the proportion and / or the nature of the water-binding component (a) in the treatment solution is particularly advantageously selected such that essentially values of fiber rigidity (detectable by the handle), fiber swelling (detectable by cross section, X-ray diffraction), dye absorption (detectable by dyeing tests) , Crosslinkability in the refining (detectable by dry and wet wrinkle recovery angle (especially with good dimensional stability), abrasion values and strength), as obtained in the conventional treatment in liquid ammonia.
• the adjustment of said pH values can be additionally supported by suitable selection and proportion of the water-binding component (a).
• the inventive method for stabilization at a temperature between -1O 0 C and 18O 0 C, preferably carried out at a temperature between 15 0 C and 105 0 C.
• the residence time is advantageously between 1 h and 4 h, with continuous implementation, the residence time in the treatment bath is advantageously between 1 and 30 min. In any case, it is important to adjust the composition of the treatment solution according to the invention of the possible treatment time.
• a high-level refinement of the cellulose fibers or of the material which in particular essentially exclusively comprises cellulose fibers is carried out.
• Processes of high-grade finishing are here and below understood to mean processes which improve the serviceability of the finished product in one or more directions in a permanent manner, in particular by changing the appearance of the goods by mechanical action (eg, ruling, moire, guarding, pleating, producing gloss effects , etc.), by chemical action (eg creation of breakthrough effects, devorant, air tips, stiffening equipment, swelling processes, stiff-finishings, lapping, softening, matting, metallization) or by combination mechanical / chemical treatment (eg Cloques, Seersucker, Köselkrepp, Craquele, Klebcloques), but also methods for increasing the utility value to effect better fullness, resistance, swelling resistance, freedom from shrinkage, crease, etc.
• the fabric's feel can be stiffer, while with reduced caustic concentration, the fabric's feel softens.
• the water retention capacity increases with higher alkali concentration, which the Differences to results of conventional liquid ammonia treatment increased.
• the high-grade finishing can be carried out after treatment with the treatment solution according to the invention either with or without intermediate drying.
• a particularly advantageous feature of the method according to the invention is that the treatment can be carried out without bonded goods guide. Due to the total reduced in the context of the invention, fiber swelling also occur much lower shrinkage forces, so that the jump of the product is lower than Mercerisierphal in the liquid phase according to the prior art.
• the invention further relates to the use of a water-binding component as additive in a treatment solution for stabilizing cellulose fibers, or of materials substantially exclusively comprising cellulose fibers, to increase the resulting proportion of cellulose fibers swollen in amorphous regions and / or to reduce the resulting proportion of cellulose fibers crystalline areas of swollen cellulose fibers.
• STK shock drying condensation.
• 40 g / l Arkofix® NDF DMDHEU-based product, Clariant AG, Basel, Switzerland
• 10 g / l MgCl 2 were used as catalyst at a liquor pick-up of about 50-70%. After drying for 1 min at 13O 0 C, condensation was carried out at 17O 0 C (duration 45 sec).
