Definitions

• yarns made from synthetic and natural fibers are generally treated with a sizing agent before weaving.
• sizing agents are polymers such as polyvinyl alcohol, carboxymethyl celluloses, polyacrylates or copolymers based on vinyl acetate, for example with crotonic acid.
• these polymers are often difficult to biodegrade, so that in recent times efforts have been made to recover the size after weaving and to use it again.
• the so-called regenerated size obtained when the size is washed out of the fabric is concentrated in these cases, for example by adding the size again, and is then available for a further size process. It is obvious that with such regeneration processes, contaminants accumulate in the regenerate over time, which can ultimately lead to difficulties on the weaving machine if such regenerated sizing fleets are used for sizing yarns.
• the invention thus relates to a process for sizing vegetable fibers, preferably cotton, and mixtures thereof with synthetic fibers using regenerated sizes, characterized in that such regenerated sizes are applied to the fibers which contain 1 to 5 g / l of a complexing agent.
• complexing agents such as alkali pyrophosphates, alkali metaphosphates, methylenephosphonic acid or aminopolycarboxylic acids and their salts (nitrilo-tri-acetic acid-Na, ethylenediaminetetraacetic acid-Na, diethylene-triamino-pentaacetic acid-Na).
• These complexing agents are added to the regenerated coatings in an amount of 1 to 5 g / l. This addition is expediently carried out simultaneously with the addition of a further amount of size, in order to bring the regenerated size back to the required concentration.
• This concentration of size in the liquor is usually about 5 to 15% by weight, the sizes are generally aqueous solutions which also contain other auxiliaries, e.g. May contain surfactants.
• Suitable sizing agents are all products which are customarily known for this purpose, such as polyvinyl alcohol, carboxymethyl celluloses, polyacrylates or copolymers of vinyl acetate and organic acids, such as crotonic acid, acyl acid, adipic acid or maleic acid.
• a yarn made of pure cotton (Nm 70/1) to produce a fine-thread, tightly knit fabric is sized with aqueous size liquors of the following composition:
• Example 2 The same yarn as described in Example 1 is sized with the following aqueous size liquors:
• the size liquor is made up with water that contains 22 meq / 1 of hardening agents.
• the measurement results show that the friction of the sized yarn is significantly reduced by the addition of the complexing agents.
• the lime soap deposits that occur when working without complexing agents clog the abrasive paper and thus reduce the abrasion effect or apparently increase the abrasion resistance.
• the lower value for the abrasion resistance in the working method according to the invention can therefore be explained by the fact that such harmful limescale deposits are avoided by the complexing agents.
