Abstract

The active ingredient of preparations for softening and antistatic treatment of textiles is a compound based on structural units I, II and III, in which Rt denotes alkyl with a number of carbons of 11 to 18, k is an integer of 1 to 3, X is an anionic residue of a strong acid, r is an integer of 2 to 6 and s is an integer of 1 to 4.

Description

The present invention relates to the use of textile compositions derived from N-aminoalkylamides of fatty acids and 1,3-bis (3-chloro-2-hydroxypropyl) imidazole or 1,3-bis (2,3-epoxypropyl) imidazole salts.

Textile auxiliaries having an imidazolinium heterocyclic backbone molecule have recently found use as cationic formulations, as well as in the preparation of reactive dyes and in other formulations. The most recent are the compounds according to AO no. 260 709, intended to stabilize dyeing with anionic dyes.

These are preparations containing the active ingredient based on structural units of formulas:

f where

R _t represents alkyl having a carbon number ll to 18, k is an integer from 1 to 3,

X is an anionic radical of a strong acid r is an integer from 2 to 6, s is an integer from 1 to 4, obtainable by reaction of compounds of the general formula (I)

R _b ras has the meaning given above,

R ₂ , R ₃ and R ₄ denote hydrogen atoms, alkyls or hydroxyalkyls having a carbon number of 1 to 22 or denote a group

R ₄ is as defined above, wherein at least one of the substituents. R ₂ , R ₃ , R 2 ₍ is hydrogen.

A detailed study of the properties of these substances revealed their further surprising effect, excellent softening capacity for both synthetic and cellulosic and natural proteinaceous materials.

Compounds derived from hexadecanoic acid, heptadecanoic acid, octadecanoic acid and nonadecanoic acid have a particularly significant softening effect.

Towards the lower acids, the softening effect decreases and dodecanoic acid derivatives are the last still softening formulations. As the softening effect decreases in a number of derivatives, the hydrophilicity of the fabrics treated therewith increases.

This criterion is particularly important for textiles containing synthetic fibers. However, there is also another newly discovered effect of AO compounds No. 260,709, the ability to eliminate static charge formation.

Antistatic activity, like hydrophilicity, is dependent on the size of the fatty acid alkyl, but is also influenced by the substituents on the nitrogen atoms of the aminoalkyl-amide chain, hydroxyalkyl substituents being particularly preferred in this regard.

On the basis of the softening and antistatic effect can be defined from a series of compounds originally protected compounds wherein strukturární group denoted by R has a substituent such as alkyl-C n _19th

The practical use of the compounds of the invention is described in detail in the following examples:

Example 1

The fabric of polyester filament yarn after dyeing is dried in conventional manner and then padded, which is introduced to a drying frame is impregnated with a liquor containing 20 g. I ^-1 Compound no. 2 of Table 1.

70% spinner, bath temperature 40 ° C. Subsequently, the fabric is dried at 120 ° C. The fabric thus treated shows a very soft feel. At the same time, an antistatic effect is achieved, the surface resistance value is 2.3. ΙΟ ⁸ Ω.

Example 2

The braided fabric of 50% cotton and 50% polypropylene silk dyed in the mass is pretreated with an alkaline whisk on the dye pad and the cellulose portion is then dyed with a reactive dye.

After dyeing and finishing operations, the fabric is treated with a bath containing 3 g. I ^"1 Compound no. 3 of Table 1.

The bath ratio is 1:10, the treatment time at 30 ° C is 15 minutes. This is followed by dewatering and drying. The knit has a very soft, pleasant touch, the surface resistance is 5.5. ΙΟ ⁸ Ω.

Example 3

The impressive hand knitting yarn of a mixture of 75% cotton and 35% polyester yarn is treated for 15 minutes at 40 ° C with a 4 g / ^l bath of compound 4 of Table 1 after dyeing in bath tubs.

Bath ratio 1: 20. This is followed by dewatering by centrifugation and drying in a curtain dryer.

The yarn has a soft, pleasant touch, the products are comfortable to wear.
