  • Mercerization is a common step in the processing of cellulosic fiber materials and concerns the treatment of these materials in aqueous alkaline liquors.
  • CH-A-192 832 describes e.g. Sulfuric acid esters of ethylene oxide adducts of aliphatic alcohols, which increase the wetting ability of the mercerizing liquors. According to CH-A-271 087, the wetting capacity of these liquors is increased by a mixture of alkyl sulfuric acids with certain alcohols and ethers. It is also known from DE-A-1 048 865 to use the sulfuric acid esters according to CH-A-192 832 in a mixture with a branched fatty alcohol as a wetting agent in the mercerization of cotton yarn.
  • Wetting agents have now been found which, when used in mercerizing liquors, overcome the disadvantages mentioned and are notable for good wetting action and very little foaming.
  • the wetting agents according to the invention always contain a C S- C 18 alcohol, for example 2-ethyl-n- hexanol, and optionally a hydrotopizing agent, for example 2,4-dihydroxy-2-methylpentane.
  • the wetting agents known from BE-A-698 817 have an inadequate wetting action, which manifests itself in the relatively low shrinking speeds of the cotton.

  • Component (c), like components (a) and (b), can be used in the form of (technical) mixtures of the alcohols in question.
  • Another component that can be used in combination with the components (a) to (d) mentioned (component (e)) is an adduct of one.

  • the wetting agents according to the invention are suitable as auxiliaries in finishing processes of cellulose-containing fiber materials. In particular, they prove to be valuable wetting agents in the mercerization of these fiber materials.
  • 1-20 preferably 2.5-10 g of the above-mentioned aqueous solutions per liter of mercerizing liquor are used.
  • Cellulose fibers for example, have a higher gloss during mercerization. At the same time, their dye absorption capacity and tear resistance are improved.
  • the fibers are mixed with concentrated alkalis (approx. 22-28%), e.g. treated aqueous solutions of lithium, sodium or potassium hydroxide or mixtures of these hydroxides.
  • concentrated alkalis approximately 22-28%

  • the main cellulose-containing fiber materials are cotton and blended fabrics with regenerated celluloses such as Cell wool and rayon (rayon) in question.
  • regenerated celluloses such as Cell wool and rayon (rayon) in question.
  • the mercerization of blended fabrics made from native (e.g. cotton, as well as hemp and flax) and regenerated celluloses places high demands on the concentration and composition of the mercerizing liquors due to the divergent properties of these components. For this reason, mixed fabrics are almost exclusively dry mercerized, which prevents additional (critical) contact of the mixed fabrics with cooking or mesh baths.
  • the mercerization is carried out as yarn or piece mercerization.
