Definitions
- the present invention relates to an improved process for treating polyamide fibers, such as, nylon or Perlon fibers with peroxide containing bleaching or washing agents wherein attack on such fibers is minimized.
- polyamide fibers are strongly attacked during treatment in bleaching or washing baths containing peroxide with the result of a considerable loss of strength of s h fibers.
- the loss in tensile strength polyamide fibers sold under the trade name Perlon can amount to 40% to 80% of their original tensile strength, when such fibers are subjected to the action of peroxide containing bleaching or washing baths at high temperatures for any substantial length of time as may occur in order to obtain satisfactory bleaching effects in polyamide fiber containing mixed fabrics or when polyamide fiber containing products are washed from time to time after having become soiled.
- the washing or bleaching baths have been stabilized with magnesium silicate, phosphates or other materials which retard the spontaneous evolution of oxygen, the same damage to polyamide fibers occurs during their use.
- the protective agents employed according to the invention are organic nitrogen compounds or their salts which contain at least two nitrogen atoms of which at least one is in the form of a primary or secondary amino group and the second of which can be of the same nature, or also be a tertiary amino group or a sulfonamide group.
- the nitrogen containing groups should be connected through a preponderantly saturated hydrocarbon chain which contains no more than 6 carbon atoms, such hydro carbon chain can also be interrupted by hetero-atoms or they can be connected through a chain forming part of a ring structure, which is of saturated or aromatic nature.
- Suitable protective substances according to the invention are for example as follows:
- the protective agents according to the invention have been found considerably more active than protective agents previously suggested and, consequently, are effective at considerably lower concentrations both in bleaching baths as well as washing.
- the protective agents according to the invention give good protection action at concentrations between 0.01 mol and 0.05 mol per liter even strongly aggressive alkaline bleaching baths.
- the quantity of protective agent employed, according to the invention, to provide good protective action can be reduced to about 0.001 to 0.005 mol per liter.
- the protective agents according to the invention are added to peroxide bleaching baths containing the normal ingredients, such as soluble silicates, magnesium sili cate or other peroxide stabilizers, alkalies, normal or anhydrous phosphates, soaps or washing agents, surface active agents, wetting agents and the like, a very good protective action upon the polyamide fibers treated in such baths, as when such protective agents are added, the normally expected 40 to loss in strength by the polyamide fibers is reduced to only about 2 to 8%
- a further advantage of the protective agents employed in accordance with the invention is that in most instances they support the bleaching power of peroxide bleaching or washing baths and undesired discolorations of the fibers are avoided.
- Example 1 A yarn of 60 denier Perlon L filaments was treated with movement for two hours at 60 C. in a bath of the following composition:
- the tearing strength of the Perlon L polyamide yarn was originally 40.2 kilometers (that is, it would sup- .port a weight equivalent to a length of such yarn 40.2 kilometers long before rupture). After the five hours treatment in the bleaching bath, its strength had only decreased to 37 kilometers or in other words, had only suffered a loss in strength of 8% of the original strength.
- Example 2 A polyamide artificial silk fabric produced from 60 denier filaments was bleached in a reel vat at 60 C. for three hours in an aqueous bleaching bath of the following composition:
- the three hours bleaching treatment only lowered the tearing strength of the polyamide artificial silk from 43.1 kilometers to 42 kilometers and consequently caused only a 2.5% loss in strength.
- Example 3 Piece goods whose warp and weft were woven from polyamide artificial silk were treated on star reel at 60 C. for 2 hours in a bleaching bath of the following composition:
- the two hours bleaching treatment only lowered the tearing strength of the warp from 43.5 kilometers to 40 kilometers and consequently only caused a 7.8% loss in strength.
- Example 4 A mixed fabric woven with a warp of 60 denier polyamide artificial silk and a weft of 100 denier viscose artificial silk was treated in loose form with movement at 60 C. for two hours in a bleaching bath of the following composition:
- the two hours treatment produced a good bleaching effect and only lowered the tearing strength of the warp from 44.2 kilometers to 42.2 kilometers and consequently only caused a 4.5% less in strength.
- Example 5 A woven fabric produced from 60 denier polyamide artificial silk yarn was treated at 60 C. for two and one half hours in a bath of the following composition:
- Example 7 Wash goods woven of polyamide artificial silk were washed at 60 C. (with light movement of the wash goods) in a washing liquid of the following composition:
- the ratio of goods to washing liquid was 1:50.
- Example 8 Wash goods woven of pclyamide artificial silk (Perlon- L-artificial silk) were washed at a temperature of 80 C. for one hour in an aqueous washing liquid containing g. per liter of a washing powder of the following composition:
- Example 9 A polyamide artificial silk fabric woven of 60 denier Perlon-L-silk was washed for two hours at 90 C. in an aqueous washing liquid of the following composition:
- peroxide as used herein, not only denotes peroxides, such as sodium peroxide and hydrogen peroxide, but also such compounds as sodium perborate, sodium percarbonate, sodium perpyrophosphate which form hydrogen peroxide in aqueous solution.
- the step which comprises incorporating in such aqueous solution 0.001 to 0.05 mole per liter an organic compound containing at least two nitrogen atoms of which at least one is in the form of an amino group selected from the group consisting of primary and secondary amino groups and any other is in the form of a group selected from the group consisting of pn'mary amino, secondary amino and tertiary amino groups, said nitrogen atoms being linked together by a chain containing up to 6 carbon atoms, the quantity of organic compound incorporated being sufficient to afford substantial protection of the fibers against deterioration during the treatment with the aqueous peroxide containing solution.
- aqueous bleaching solution containing a peroxide in a quantity to provide an active oxygen content of up to about 5 g. per liter
- the step which comprises incorporating in such aqueous bleaching solution 0.001 to 0.05 mole per liter an organic compound containing at least two nitrogen atoms of which at least one is in the form of an amino group selected from the group consisting of primary and secondary amino groups and any other is in the form of a group selected from the group consisting of primary amino, secondary amino and tertiary amino groups, said nitrogen atoms being linked together by a chain containing up to 6 carbon atoms, the quantity of organic compound incorporated being sufficient to afford substantial protection of the fibers against deterioration during the treatment with the aqueous peroxide containing solution.
- the step which comprises incorporating in such aqueous washing solution 0.001 to 0.005 mole per liter an organic compound containing at least two nitrogen atoms of which at least one is in the form of an amino group selected from the group consisting of primary and sec: ondary amino groups and any other is in the form of a group selected from the group consisting of primary amino, secondary amino and tertiary amino groups, said nitrogen atoms being linked together by a chain containing up to 6 carbon atoms, the quantity of organic compound incorporated being sufiicient to afford substantial protection of the fibers against deterioration during the treatment with the aqueous peroxide containing solution.
