SU840218A1 - Dry cleaning intensifier - Google Patents

Description

The invention relates to chemical processing of fibers and articles thereof, in particular to the processing of clothes during the process of dry cleaning. A power amplifier for treating textiles in a white spirit environment is known, which contains ammonium salts of butyl oxystearic acid sulfoester, washing paste Novost, lecithin (natural phosphatide), cyclohexanol, and white spirit flj. However, this amplifier is ineffective and has a dark color, which negatively affects the processing of 15 light-colored textiles. In addition, it is a single function amplifier. The closest to the offer is a dry-cleaning booster based on mono- and dialkyl phosphates of higher fatty alcohols. However, the known booster does not provide high anti-resorption and bactericidal properties, does not prevent the leaching of fats from the leather base of fur, hair and skin. The purpose of the invention is to improve the quality of dry cleaning and impart bactericidal properties. t and with d t ve and sl sl and no chi. The goal is achieved that an amplifier based on monodialkylphosphates of higher fatty ryts (ji additionally contributes mono- or diethanolamides of synthetic fatty acids, sterile or vaseline oil ortho-hydroxybenzoic acid with a ratio of components, pp.%: Fatty alcohol monoalkyl phosphates C -, - C2) Di alkyl phosphates of fatty alcohols C-C, 1o Mono- or diethanolamides of synthetic fatty acids, Spun or vaseline oil 10-15 Ortho-hydroxybeneic acid 5-10 Offer enhancer get food conductive manner. The calculated amounts of the mixture of monodialkyl phosphates obtained on the basis of primary fatty alcohols

the amount of mono- or diethanolamides of synthetic fatty acids, the latter being preheated to 50-60 ° C until complete melting. Into the resulting mixture is introduced by faithHHoe or liquid paraffin and ortho-hydroxybenzoic acid. The mixture is thoroughly mixed and set for 10-30 minutes.

Example. To check the properties of the proposed amplifier, three mixtures of ingredients are prepared, the ratio of which is given in Table 1.

Mixtures are treated with samples contaminated with a suspension of the following composition, g / l:

Lamp soot 0.3 Sunflower oil 0.75

Prepared tissue samples are loaded into a vessel containing 1 g of the prepared composition of the chemical purge enhancer in 1 liter of perchlorethylene (PCE), where they are treated for 15 min at room temperature and with continuous stirring. After annealing, the samples are dried.

To obtain comparative data on the effectiveness of stripping, parallel processing of similar samples is carried out with a known composition. When testing tissue samples in PCE and white spirit, powerful anti-sorption abilities and physical and mechanical properties are determined by standard methods.

Together with textile samples of wool, the processing of fabrics from synthetic fibers is carried out, in which, after processing, the specific surface area of electrical resistance is examined at the IEV facility.

The test results are shown in table 2.

As can be seen from Table 2, the samples treated with the proposed composition of washing ability and antistatic properties are superior to samples treated with a known composition. In addition, the use of the proposed composition, due to the presence of spun or petroleum jelly, reduces the extraction of fatty substances from the leather base of fur and leather products, which is of great importance in the dry cleaning of outerwear. The booster also provides a bactericidal effect to the workpiece. Application of the predlozhenie 2
