Definitions

  • This invention relates to a method of imparting wrinkle and/or crease and/or shrink resistance and/or smooth drying properties to fabrics made from cellulosic fibres or yarns or blends containing cellulosic fibres or yarns. More particularly it relates to such a method of treatment which does not involve the use of formaldehyde or formaldehyde derivatives or phosphorus containing compounds.
  • Such properties can be imparted to cellulosic fabrics by a finishing treatment with resinous compositions.
  • the most commonly used resins for such finishing are based on formaldehyde derivatives such as formaldehyde-urea or substituted urea addition products such as DMEU and DMDHEU.
  • formaldehyde derivatives such as formaldehyde-urea or substituted urea addition products such as DMEU and DMDHEU.
  • Such resins are believed to function by promoting crosslinking of the cellulose in the fabric thereby imparting the desired properties.
  • crosslinking agents which do not include formaldehyde or its derivatives to remove the possible evolution of formaldehyde during manufacture, storage and/or use of cellulose, particularly cotton fabrics, treated with formaldehyde addition products.
  • Non-formaldehyde crosslinking agents which have been suggested previously include polycarboxylic acids as disclosed by Gaghiardi and Shipee, American Dyestuff Reporter 52, 300 (1963). Rowland et al., Textile Research Journal 37, 393 (1967), disclosed the use of partially neutralized polycarboxylic acids with base prior to the application to the fabric in a pad, dry and heat cure treatment, elaborated US Patent 3526048. Canadian Patent No 2097483 describes rapid esterification and crosslinking of fibrous cellulose in textile form using boric acid or derivatives as crosslinking catalyst.
  • the present invention is based on the discovery that certain hydroxycarboxylic acids and/or their salts, particularly alkaii metal salts at lower concentration show accelerating effect on esterification and crosslinking of cellulose by polycarboxylic acids.
  • the use of such catalysts can enable the provision of a treatment method that uses neither formaldehyde derivatives or phosphorus compounds, but can give adequately rapid esterification and crosslinking of cellulosic in fibres to provide effective wrinkle, crease or shrink resistance or smooth drying properties to materials made from such cellulosic fibres.
  • fibrous cellulosic material is treated with a polycarboxylic acid in the presence of a hydroxycarboxylic acid curing catalyst at elevated temperature.
  • the process can be carried out by impregnating the material with a solution containing the polycarboxylic acid and the curing catalyst followed by heat treatment to produce esterification and crosslinking of the cellulose with the polycarboxylic acid.
  • the present invention accordingly provides, a method of treating fibrous cellulosic textile material which comprises: a applying to the cellulosic textile material an aqueous solution including at least one polycarboxylic acid as a crosslinking agent for the cellulose and a hydroxycarboxylic acids or a salt as an esterification catalyst, b drying the textile material and heating it to promote crosslinking esterification of the polycarboxylic acid and the cellulose of the cellulosic textile material.
  • the material as being “cellulosic” we mean that the major part of the fibre forming components of the material is cellulose.
  • the term includes purely cellulosic materials such as cotton and cellulose-rich blends particularly cellulose-rich polyester blends, such as polycotton materials.
  • the material contains from 30 to 100% of cellulosic fibres.
  • Typical cellulosic fibre materials which can be included in fabrics treated according to this inventions include cotton, flax, rayon, jute, hemp and ramie. It can also be a synthetic cellulosic fibre material such as rayon, particularly viscose rayon or solvent derived rayon commonly called lyocell fibre.
  • the cellulosic material can be a blend of fibres of cellulosic materials with non-celiulosic materials and in particular includes blends of cellulosic fibres, particularly cotton, with polyester, particularly polyethylene terephthalate polymer or related copolymers.
  • the textile can be a woven (including knitted) or non-woven textile, but as crease resistance is particularly important in clothing, the textile will usually be a clothing textile material.

Abstract

On traite une matière cellulosique fibreuse par application d'une solution aqueuse d'un agent de réticulation d'acide polycarboxylique et d'un acide hydroxycarboxylique, notamment un acide carboxylique aromatique o-hydroxy, spécialement de l'acide salicylique ou un sel, particulièrement, des sels d'ammonium de métal alcalin ou de métal alcalino-terreux, en tant que catalyseur d'estérification. On fait ensuite sécher le tissu et on le chauffe pour favoriser l'estérification avec réticulation de l'acide polycarboxylique et de la celluloses de la matière cellulosique fibreuse et ce, afin d'obtenir un tissu dont la résistance au pli de froissement et/ou à la cassure et/ou au retrait est améliorée à l'instar de ses caractéristiques de séchage facile. Cette technique présente l'avantage de ne pas exiger le recours à des dérivés de formaldéhyde et, de ce fait, il n'y a pas de libération de formaldéhyde durant le traitement susmentionné. De même, les matières traitées ne libèrent pas de formaldéhyde au moment de la fabrication du tissu ni à l'utilisation. Un autre avantage réside dans le fait que les catalyseurs ne contiennent pas ni n'utilisent des composés renfermant du phosphore.
