Definitions

• sizing compositions having a gelatine basis often give rise for various reasons, which are not completely understood, to irregularities which manifest themselves for example, by variations in the rigidity of the sized threads, by defective agglomeration of the filaments, by bad wetting of the threads by the sizing composition, and by insufiicient adherence of the latter, or by other phenomena giving rise to ditficulties in the subsequent weaving.
• compositions according to the invention enable an excellent sizing of great uniformity to be obtained on all fibres and particularly on the water-repellent fibres mentioned above. They are characterized by the fact that in addition to gelatine they contain a salt of an oxygenated acid with an organic base containing at least one hydroxyl group, which for convenience will hereinafter be referred to as an hydroxylated organic base.
• the bases which can take part in the salts to be used can be monoor poly-hydroxylated, as, for example, the mono-, diand triethanolamines or dimethylaminoethanol.
• the oxygenated acids can be mineral acids such as nitric or sulphuric acid, or organic acids such as acetic acid.
• the salts of the hydroxylated organic bases can be introduced into the aqueous solution of the gelatine in any desired manner, either before or after dissolving the gelatine or in the course of this operation.
• the sizing compositions can contain one or several salts of the hydroxylated organic bases.
• the new sizing compositions can be used at any desirable pH.
• the sizing compositions according to the invention although they are particularly valuable for water-repellent Example 1 5 kg. of gelatine are caused to swell in 10 kg. of water for 12 hours. The swollen mixture is heated to 55 C. to dissolve the gelatine completely, and 4.3 kg. of triethanolamine nitrate are added to it and then kg. of water and the whole well mixed by stirring.
• This composition is brought to a temperature of 55 C. and is used on a machine of the known type for sizing;
• the wetting of the warp is excellent and the filaments are very regularly agglomerated even when the amount of the size is only 3.2%.
• this warp in weaving is particularly good; an identical warp sized with the same quantity of a composition of gelatine and a metallic nitrate instead of the organic nitrate of the present invention behaves badly on weaving.
• Example 2 5 kg. of gelatine are caused to swell for 12 hours in 10 kg. of water at a temperature of 22 C. The mixture is heated to 5 5 C. until the gelatine has completely dissolved and 2.5 kg. of triethanolamine sulphate are added to it with stirring at pH 7.5.
• This mixture is diluted to 100 litres by the addition of water and the product is heated to 60 C.
• a warp formed of threads of cellulose acetate of 100 deniers is sized with this composition at 60 C. This warp is very well sized and its behavior on weaving is excellent.
• Example 3 4.5 kg. of gelatine are swollen in 7 kg. of water as described in Example 1 and dissolved at 55 C. 3.2 kg. of diethanolamine nitrate is added to this solution and then kg. of water with stirring. The composition obtained is heated to 45 C. before being used to size a warp formed of superpolyamide threads of 45 deniers and 28 filaments. 4.6% of the size remain on the threads the filaments of which are very well agglomerated. The thread is very readily woven.
• Example 4 A thread of 190 deniers consisting of 60 filaments of polyvinyl chloride is sized with a composition containing:
• the sizing is carried out at 45 C. continuously on a twisting machine.
• a warp is obtained of excellent properties having threads of which the filaments are perfectly agglomerated.
• Example 5 A continuous thread of cellulose acetate of deniers containing 18 filaments is sized at 45 C; on a twisting machine with a composition containing:
• Example 6 A thread of cellulose acetate of 100 deniers consisting of 18 filaments is caused to pass through a solution containing:
• a sizing agent for all kinds of textiles which consists of an aqueous solution of gelatine containing 2 to 6% by If 0 weight of diethanolamine nitrate.
