CS264928B1 - Preparation for softening, antistatic treatment and simultaneous stabilization of textiles during home washing - Google Patents

Abstract

The softening antistatic agent for application to fabrics after household laundering with the present anionic dyeing effect is based on the use of compounds of the formula I wherein Rp is a carbon residue of 11 to 22 carbon atoms, R2, r3 are hydrogen, alkyls of hydroxyalkyl with carbon numbers 1 to 4, n is an integer of 2 or 3, s is an integer of 1, 2 or 3, X is an anionic moiety, k is an integer of 1, 2 or 3, emulsifying, perfuming and coloring agents. The product is particularly suitable for use in automatic washing machines.

Description

The present invention relates to a composition for softening, antistatic treatment and at the same time stabilizing dyeing and printing with anionic dyes in domestic washing.

The use of fabric softeners in domestic washing, especially in automatic washing machines, has become an essential part of the washing process. This operation is important not only for textiles containing synthetic fibers, with a view to suppressing the build-up of static charge when worn, but is also important for natural fibers, eliminating the strong degreasing effect of modern laundry detergents.

When washing in automatic washing machines, it is often the case that after the end of the entire washing program, the fabrics are either spun or in the last, i.e., stacked, bath, often for a long time. Cellulose textiles dyed with substantive or reactive dyes may release dye and embed into other materials at this stage. The same applies to polyamide materials. Printed textiles are particularly dangerous in this respect. Unfortunately, the current household fabric softeners used in the last spas have no stabilizing effects.

These drawbacks are solved by the softening composition according to the invention, which is characterized not only by a very good softening and antistatic effect, but also by a marked stabilizing effect for anionic dyes.

According to the invention, the compounds protected by MS. AO No 260 709,

263 826, 262 225, optionally emulsifying components, perfume and color additives. Own active substance that provides both softening, antistatic and stabilizing effect can be characterized by a general formula

R _ * ~ κ ¹ I \ R _{N 2} - _{[(CH2) n} -NR _{3 J,} - CH ₂ -CH ₂ -N-CH-N-CH ₂ -CH-CH ₂ -Cl, ^OH OH where a C 11 -C 22 carbon residue

R 1, R 1 are hydrogen atoms, alkyls or hydroxyalkyls having a carbon number of 1 to 4 n is an integer of 2 or 3 s is an integer of 1, 2 or 3

X is an anionic moiety k is an integer of 1, 2 or 3

Preferably, mixtures of two materials may be used, wherein the first R @ 6 is a saturated carbonaceous moiety having from 11 to 22 carbons, and the second one is a saturated radical having from 15 to 22 carbon atoms.

The first component with a saturated residue R1 provides a very soft effect, the second component enhances the antistatic effect and improves the water solubility of the system, with both components having the same stabilizing effect.

Table 1 lists the formulas of the basic compounds useful for making the softening compositions of the present invention.

The preparation procedures and properties of the formulations are included in the following examples:

Example 1

In a boiler equipped with a heating coil and a stirrer, 50 kg is dissolved in 300 l of 60 ° C warm water

CS 264 928 B1 paste containing 25% of Compound No. 1 of Table 1 and 50 kg of Compound No. 5 of Table 1 Next, add 8 kg of coconut N, N-di (2-hydroxyethyl) amide, 800 g of apple perfume and 80 g of dissolved dye Base green No. C1 1.

After thorough mixing, the mixture is ready for filling into polypropylene bottles.

Example 2

In the automatic washing machine Tatramat 353, 4 kg of cotton underwear is washed at 40 ° C according to the program for color-fast laundry. To the last rinse bath is added 60 g of the preparation according to Example 1. Centrifugation follows. The laundry shows a soft effect after drying. The washing of the laundry before drying is prevented.

Example 3

In the washing machine according to Example 2, 6 men's shirts of a blend of 65 and polyester and 35% cotton fibers are washed according to the synthetic material program. 50 g of the composition of Example 1 are dispensed into the last rinse bath. After drying, the shirts exhibit a soft touch, their soiling is suppressed by suppressing the formation of static charges.
