摘要:
Conditioning systems for polyester fibers consisting of from 40 - 60% by weight of a lubricating agent and from 60 to 40% by weight of an emulsifying mixture, the total conditioning system showing a loss by evaporation of less than 5% by weight at 220.degree. C within 1 hour, a viscosity of less than 200 cP (20.degree. C), and in dilution with water in the ratio of 2:1, 1:1 and 1:2, a viscosity of less than 150 cP, less than 500 cP and less than 250 cP (60.degree. C), respectively. These compositions are applied onto the fibers by known methods. They impart especially good sliding properties to the polyester fibers during texturizing.
摘要:
The invention provides a process for the manufacture of viscoses from hemicellulose-containing cellulose pulps without requiring dialysis equipment. By addition of substances having a cross-linking or blocking action on the active groups of hemicellulose to the pulp before or during steeping it is possible to reduce the use of NaOH and CS.sub.2 in the manufacture of viscoses.The viscoses so obtained are distinguished by good filterability and low content of compounds causing formation of H.sub.2 S in the spinning process.

C.;(b) from 2 to 10% of one or several alkyl imidazolines of the formula I ##STR1## in which R is C.sub.12 -C.sub.22 -alkyl, alkenyl or hydroxyalkyl,R.sub.1 is hydrogen or C.sub.1 -C.sub.22 -saturated or unsaturated aliphatic or aromatic acyl,R.sub.2 is hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -hydroxyalkyl,n is a number of from 2 to 6, andX is a halogen anion, a C.sub.1 -C.sub.4 -alkyl sulfate anion, a C.sub.1 -C.sub.4 -dialkyl phosphate anion, or a C.sub.1 -C.sub.4 -alkyl carboxylate anion;(c) from 1 to 5% of one or several aminoxides of the formula II ##STR2## in which R is C.sub.8 -C.sub.12 -alkyl or alkenyl,R.sub.1 is C.sub.1 -C.sub.4 -alkyl,R.sub.2 is hydrogen or C.sub.1 -C.sub.4 -alkyl, andn is a number of from 0 to 6, and (d) from 5 to 20% of one or several polyglycol ethers of the formula IIIR--O--(C.sub.2 H.sub.4 O).sub.n --H III, in whichR is C.sub.8 -C.sub.18 -alkyl or alkenyl andn is a number of from 3 to 12, as well as water ad 100%.
摘要:
Fiber conditioning agent containing a reaction product of polyphosphoric acid and an oxalkylate of C.sub.8-18 alkyl- or alkenylcarboxylic acids with 1 to 22 ethylene oxide units and having a content of free polyethylene glycol of less than 2% by weight, the reaction product being present in acidic form or in the form of its alkali metal salts. These fiber conditioning agents are applied by conventional methods. They show good antistatic properties, are stable to heat and show good lubricating and sliding properties.
摘要:
The urethanes described are synthesized from aliphatic fluoro alcohols, triisocyanate and a carboxylic acid. They are prepared by reaction of the aliphatic fluoro alcohol with the triisocyanate to give the fluoro alcohol/triisocyanate adduct and by reaction of this adduct with the carboxylic acid. The new urethanes are preferably used for the finishing of textiles for the purpose of achieving water, oil and soil repellency.
