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.

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.
