CS277463B6 - A water-based fabric hardening agent with stabilized perfume effect - Google Patents

Abstract

The aqueous preparation for stiffening textiles contains 5 to 20% by weight of stiffening component, 0.1 to 1% by weight of perfume and 0.3 to 3% by weight of the compound of general formula I.

Description

The invention relates to an aqueous preparation for stiffening textiles with a stabilized perfuming effect after washing and drying. It is particularly advantageous in consumer laundry care.

Stiffening laundry, especially bed linen after washing, is an essential part of the maintenance process. Stiffening not only serves an aesthetic purpose. The film created protects the fabric to a certain extent from contamination and contributes to better removal of dirt during the next wash.

Starch used for stiffening is gradually being replaced by synthetic film-forming substances, mainly based on polyvinyl alcohol and polyvinyl acetate.

Preparations containing starch and synthetic stiffening agents are known and commonly produced even for small consumers. Such preparations are usually perfumed. However, the effect of perfume is usually functionally imperfect. It affects the consumer when purchasing the preparation and applying it. Often the effect disappears when the laundry is dried and is no longer noticeable after heat treatment of the laundry, i.e. ironing or mangling.

The above disadvantages are eliminated by an aqueous preparation for stiffening textiles with a stabilizing perfuming effect after washing, which contains by weight 5 to 20% of a stiffening component selected from the group comprising polyvinyl alcohol, polyvinyl acetate, oxidized starch or the same amount of a mixture of these substances, according to the invention. Its essence is that it contains, based on the weight of the preparation as a whole, 0.1 to 1% of perfume and 0.3 to 3% of a compound of the general formula I

where X is an anionic residue and k is an integer 1, 2 or 3.

It is one of the substances that has proven itself as a preparation for finishing dyeing with anionic dyes according to Czechoslovak copyright certificate No. 262 225.

The substance of general formula 1 has recently been shown to have an excellent ability to emulsify perfume additives into stiffening preparations and protect them during heat exposure until drying. This significantly increases the stability of the perfume of stiffened textiles.

To achieve a sufficient effect, it is necessary to dose 1 to 2 parts of the compound of general formula 1 per one part of the perfume component, with the dosage of perfume in the stiffening preparation being 0.1 to 1% by weight. The stiffening component of the preparation may be oxidized starch or, more preferably, carboxymethyl cellulose ether, polyvinyl alcohol or polyvinyl acetate, in a dosage of 5 to 20% by weight, calculated on dry matter.

The preparation and use of the compositions according to the invention are shown in the following examples. The % given are % by weight.

Example 1

In a boiler equipped with a stirrer, 300 kg of a 15% aqueous solution of polyvinyl alcohol is diluted in 350 liters of water at a temperature of 20 °C. Next, 300 kg of a 10% non-plasticized polyvinyl acetate dispersion is gradually added. In a separate container, 10 kg of compound No. 1 from Table 1 and 5 kg of perfume are mixed, 10 liters of warm water at 30 °C are added and, after mixing, the mixture is slowly poured into the boiler. The total weight is adjusted to 1,000 kg by adding 15 kg of water.

A similar effect can be achieved if the same amount of compound 2 or 3 is used instead of compound 1 from Table 1.

Example 2

A 120 kg load of bed linen is washed using the usual technology in a semi-automatic PAC 120 washing machine. In the last phase, the stiffening agent according to example 1 is applied in an amount of 4,320 g, by placing it directly into the dosing container. The actual stiffening passage at a temperature of 20 °C is 7 minutes. The laundry is then spun, removed from the machine, dried and ironed in the usual way. The laundry exhibits optimum stiffness and a permanent perfumed effect.

Example 3

A load of 4 kg of tablecloths and tea towels is washed in the ROMO 400 automatic washing machine using the usual program. In the last phase of the washing cycle, a 60 g stiffener is applied by placing the dose directly into the dosing container. The actual stiffening passage at a temperature of 20 °C is determined by the automatic washing machine program. This is followed by spinning, removal from the washing machine, drying and ironing in the usual way. The tablecloths and tea towels have optimal stiffness and a permanent scent.
