Definitions
- the present invention relates to modified polyamides and a process for making them.
- the affinity of polyamides for acid dyestuffs depends on the salt formation with the terminal amino groups.
- the number of the terminal amino groups has therefore been reduced, for example, by a reaction with carboxylic acids or carboxylic acid esters which have been added to the melt.
- strongly acid groups of, for example, sulfuric acid nature must be introduced.
- Modified polyamides the afiinity of which for acid dyestuffs is more or less reduced, but which can be dyed with basic dyes, can be obtained by incorporating aromatic and araliphatic sulfocarboxylic acids or the sulfonates thereof, for example those of the alkali metals.
- the sulfo group is attached to the aromatic nucleus or to an alkoxy side chain.
- the carboxyl groups of the sulfonate esters are esterified with a low aliphatic alcohol with 1 to 6 carbon atoms, for example, methanol, ethanol, nand i-propanol, n-butanol, n-pentanol and n-hexanol.
- a low aliphatic alcohol with 1 to 6 carbon atoms for example, methanol, ethanol, nand i-propanol, n-butanol, n-pentanol and n-hexanol.
- the sulfonate groups particularly the ions of lithium, sodium and potassium form the cations. Mixtures of the sulfonates with sulfonate esters may likewise be used.
- the above number of 2 to 18 carbon atoms of the aliphatic sulfocarboxylic acids is not intended as a limitation, but is the preferable number, i.e. derivatives of aliphatic sulfocarboxylic acids with more than 18 carbon atoms may also be used. It could not be foreseen that sulfonates and sulfonate esters of aliphatic sulfocarboxylic acids also make suitable modifiers for the manufacture of polyamides as the thermostability of these compounds is inferior to that of the derivatives of aromatic and araliphatic sulfonic acids known as polyamide modifiers and since these compounds are exposed to considerable thermal stress during polycondensation.
- suitable polyamide modifiers are the following substances (for clarity, only the basic compounds and not their sulfonates or sulfonate esters have been enumerated): sulfoacetic acid, 2-sulfopropionic acid, 3-sulfopropionic acid, 4 sulfobutyric acid, 2-sulfoisobutyric acid, 2-sulfo-4-hydroxybutyric acid, 2-sulfopalmitic acid, 2-sulfostearic acid, u-sulfophenylacetic acid, Z-sulfoadipic acid, 2,5-disulfoadipic acid and 2-sulfovinyl-acetic acid.
- Compounds of this type may also contain inert substituents, for example, alkyland alkoxy groups or halogen atoms. Particularly good dyeing effects are obtained with the use of derivatives of aliphatic sulfocarboxylic acids containing hydroxyl groups.
- the derivatives of the said compounds may be used as such as in admixture with one another.
- the sulfonates and sulfonate esters of aliphatic sulfocarboxylic acids are easy to obtain.
- Halogenated carboxylic acid esters may, for example, be reacted with metal sulfites, or carboxylic acids may be sulfonated and the sulfocarboxylic acids primarily formed may be converted into the sulfonates or the esters thereof.
- the sulfonate esters are in many cases more easy to obtain synthetically than the free carboxylic acids and are therefore advantageously used for the process of the invention.
- any known polyamide-forming substance may be used, preferably the lactams, aminocarboxylic acids and neutral salts of dicarboxylic acids and diamines commonly used for this purpose, for example, -e-CE1PI'O- lactam, e-aminocaproic acid and the neutral salt of hexamethylene-diamine and adipic acid (hexamethylenediammonium adipate, designated hereinafter AH-salt).
- the modifiers are generally added in the form of the solid, finely powdered substances or in the form of an aqueous solution thereof.
- the addition is advantageously made at the beginning of the polycondensation which is carried out in the same manner as without modifiers. It is also possible to add them at another moment during or after the polycondensation. Small amounts of other substances, for example, dulling agents or substances protecting against the action of light, may also be added.
- the products obtained by the process of the invention are colorless. Their melting points differ only little from those of unmodified polyamides. They can easily be formed by the usual methods, for example spun on extruders to drawable filaments. The extraction with hot water usually carried out to remove proportions of low molecular weight may be carried out before or after forming.
- the shaped articles made from the polyamides of the invention for example, films, fibers and filaments, have substantially no receptivity for acid dyestuffs, but are dyed deep tints by basic dyestuffs. By dyeing mixtures of these fibers with normal polyamide fibers in a single bath, using acid and basic dyes together, contrary multicolor effects of high brilliance can therefore be obtained.
- the following examples serve to illustrate the invention, but are not intended to limit it.
- EXAMPLE 1 In a vessel with stirring means, 40 kilograms of caprolactam were melted under a nitrogen atmosphere. At a temperature of 160 C., 2.4 kilograms of AH salt, 60 grams of titanium dioxide in the form of a aqueous dispersion, 300 grams of the sodium sulfonate of sulfoacetic acid and 3.2 grams of manganese acetate-4H O were added. The temperature was raised to 260 C. within 2 hours, water and a small amount caprolactam being distilled off. The melt was kept at 260 C. until the melt viscosity remained almost unchanged, which could be recognized by the performance of the stirring means. The melt was then discharged into cold water and the solidified white polyamide was made into chips.
- the granular product was extracted three times at 95 C. with three times the amount of distilled water and dried under strongly reduced pressure.
- the relative viscosity determined in a solution of 0.2 gram polyamide in milliliters sulfuric acid of 95.5 strength, was 2.89.
- the chips were spun in known manner from the melt and the resulting tow was drawn at a ratio of 123.6.
- the filament so obtained was dyed only little by acid dyes, but was dyed deep tints by basic dyes.
- excellent contrary multicolor effects were obtained in a single dyebath with combinations of acid and basic dyestuffs. Because of its high relative viscosity, the filament is very suitable for the manufacture of tufted carpets.
- EXAMPLE 2 The polycondensation was carried out in the manner described in Example 1, but while using, instead of the sodium sulfonate of sulfoacetic acid, 280 grams of the sodium sulfonate of sulfoacetic acid methyl ester. A polyamide of a relative viscosity of 2.92 determined in the manner described in Example 1 was obtained which could very well be spun and drawn. The filament had exactly the same good tinctorial properties as the filament of Example 1.
- EXAMPLE 3 A mixture of 550 grams of caprolactam, 33 grams of AH salt and 4.5 grams of the sodium sulfonate of 2- sulfopropionic acid was melted under nitrogen and heated to 270 C. within 2 hours, while stirring. The process was then carried out in a manner analogous to that of Example 1.
- the colorless polyamide so obtained had a relative viscosity of 3.03 determined in the manner described in Example 1 and had the tinctorial properties described in Example 1.
- EXAMPLE 4 In the manner described in Example 3, 550 grams of caprolactam, 33 grams of AH salt and 4.4 grams of the sodium sulfonate of 4-sulfobutyric acid were polycondensed. The resulting polyamide had a relative viscosity of 3.05 determined as described in Example 1, and could very well be dyed different colors in the manner described in Example 1.
- EXAMPLE 5 4.7 grams of the sodium sulfonate of 2-sulfoisobutyric acid were polycondensed in the manner described in Example 3 with the amounts of caprolactam and AH salt also indicated in that example. The resulting polyamide had a relative viscosity of 3.10 determined as described in Example 1 and the same good tinctorial properties as the polyamide of Example 1.
- EXAMPLE 6 The process was carried out in the manner described in Example 3, but while using, instead of the sodium sulfonate of 2-sulfopropionic acid, 8.8 grams of the sodium sulfonate of 2-sulfopalmitic acid.
- the polyamide so obtained had a relative viscosity of 3.00 determined in the manner described in Example 1, and could be excellently dyed in the manner described in Example 1.
- EXAMPLE 8 550 grams of caprolactam, 33 grams of AH salt and grams of the sodium sulfonate of 2-sulfo-4-hydroxybutyric acid were polycondensed in a manner analogous to that of Example 3.
- the polyamide so obtained had a relative viscosity of 2.77 determined as described in Example 1, and could particularly well be dyed in the manner also described in that example.
- EXAMPLE 9 550 grams of caprolactam and 33 grams of AH salt were polycondensed in the manner described in Example 3 while adding 6.1 grams of the sodium sulfonate of 2- sulfoadipic acid. The resulting polyamide had a relative viscosity of 2.80 determined as described in Example 1, and could be dyed different colors in the manner described in Example 1.
