Definitions
- the invention relates to the use of fibers made from modified cellulose hydrate in the production of bound nonwoven fabrics capable of absorbing water vapor, and to products produced in this way.
- Bound non-woven fabrics i.e. H.
- Nonwoven fabrics bound by chemical binders are of interest for various technical fields of application, including their substitute applications, above all for leather or certain textiles in their fields of application, eg. B. for shoes, (shoe upper, lining, soles), bags, upholstery, outer clothing (“leather” and all-weather clothing) or for textiles or household aids (tablecloths, window “leather”, wipes), but also their combined or complementary Applications with materials such as leather or textiles that can be used in these areas in addition to the nonwovens.
- the use of bonded nonwovens in these areas has been known for a long time.
- the invention is based on the object of proposing the use of such modified cellulose hydrate fibers in which they have their characteristic properties To be valid.
- This object is achieved according to the invention by the use of fibers made of cellulose hydrate modified by an organic, polymeric compound in the production of bonded nonwovens capable of absorbing water vapor, alone or in a mixture with synthetic, natural or regenerated fibers.
- nonwovens For the production of water vapor absorbent bonded nonwovens, reference is made to DE-OS 27 10 874.
- methods for the production of nonwovens are carded nonwovens, nonwovens obtained by pneumatic means, spunbonded nonwovens or nonwovens which are used in the wet way, for. B. manufactured in a paper machine called.
- the basic constituent of the nonwovens according to the invention can be synthetic, natural or regenerated fibers, in particular of polyester, polyamide, polyacrylonitrile, polyvinyl chloride, acetate, alcohol, cotton, rayon, collagen, regenerated cellulose, polyurethane or mixtures thereof.
- the fibers of modified cellulose hydrate are added to these fibers before or during the production of the nonwoven and are evenly incorporated therein.
- Suitable fibers for the use according to the invention are, in particular, those in which the viscose modifying agent or a comparable stage is added to the fiber during the manufacture prior to shaping (regeneration). Provided that it is water-soluble and alkali-soluble, this modifier is only added shortly before the spinneret or, if it is water-insoluble and alkali-insoluble, even before the cellulose is xanthated.
- organic polymers such as water- and / or alkali-soluble or water- and / or alkali-insoluble natural or synthetic polysaccharides or polysaccharide derivatives based on starch, cellulose, guar, alginic acid and alginates, galactomannans, arabinogalactanes or pectins (see for example AALawrence "Edible Gums and Related Substances", Noyes Data Corp., Park Ridge / New Jersey, 1973), in particular these are cellulose ethers such as CMC, HEC, MC, EC or their mixed ethers, corresponding starch or guar ethers and alginates; Acrylic polymers, methacrylic polymers or their mixed polymers, in particular polyacrylic acid, polymethacrylic acid, partially hydrolyzed polyacrylamides, partially hydrolyzed polyacrylonitriles or the corresponding salt forms.
- organic polymers such as water- and / or alkali-soluble or water- and / or al
- the coating can be carried out in one operation with the binding of the nonwoven - in particular according to the method described above
- these coating processes are generally known and are described, for example, in Plastics Handbook, Volume VII, "Polyurethane", by R. Vieweg and A. Höchtlen, Carl Hanser Verlag, Kunststoff (1966) or Volume II (Parts 1 and 2), "Polyvinylchloride” K. Krekeler and G. Wick, Carl Hanser Verlag, Kunststoff (1963).
- the nonwovens according to the invention have good water vapor absorption and permeability, which goes beyond a pure transport effect of the incorporated fibers from modified cellulose hydrate.
- the nonwovens are also able to release the absorbed water vapor under certain conditions, such as staying in a different climate.
- the mentioned properties of the bonded nonwovens are not based solely on the significantly detectable effect due to the addition of the fibers from modified cellulose hydrate, but rather a. are also dependent on the thickness of the nonwovens, these are expediently produced in a thickness of about 0.1 to 5 mm or split to this thickness.
- the bonded nonwovens according to the invention with the properties mentioned are suitable, for example, as self-supporting nonwovens (e.g. as shoe linings, insoles) or as supports for coatings with synthetic materials for use as shoe uppers, upholstery covers, baggage goods and outerwear ("leather" and all-weather clothing) , in particular as a carrier for coatings to a synthetic leather.
- Example 1 The procedure of Example 1 is followed, but with 90 g of a partially hydrolyzed polyacrylonitrile as modifier and with a weight ratio of cellulose hydrate to modifier such as 7.33 to 1.
- Example 1 The procedure of Example 1 is followed, but with 100 g of the sodium salt of carboxymethyl cellulose as a modifier and with a weight ratio of cellulose hydrate to modifier such as 3.17 to 1.
- Example 1 The procedure of Example 1 is followed, but with 25% of the modified cellulose hydrate fibers and 75% of the polyester fibers.
- Example 2 The procedure of Example 2 is followed, but with 25% of the modified cellulose hydrate fibers and 75% of the polyester fibers.
- the modified cellulose hydrate fibers produced as described in Example 1 are bound with an unmodified fiber without prior mixing.
- bonded nonwovens of Examples 1 to 6 are compared in their water vapor absorption capacity with a bonded nonwoven (100% polyester fibers, 1.7 dtex, 40 mm long) which contains no modified cellulose hydrate fibers (Comparative Example V1).
- WDA 95 means that the sample is exposed to a relative humidity of 95% at a temperature of 23 ° C starting from a relative humidity of 50% for a certain period (4 or 8 hours).
- WDA 91 then means a relative humidity accordingly of 91%.
