The shelf life of cotton wool. Surgical hygroscopic wool: material production

Gigroscopic Vata.

The substance is peeled cotton wool, devoid of fat, etc. The beams that can be easily saved with water and absorb it, and therefore used in surgical practice as a korpio. Vata is extracted from raw cotton by cleansing it, primarily on special machines, freeing cotton from seeds and husks, sand and dust. Next, the fibers of cotton are released from cotton oil contained in them and other fats - degreased - long and re-boiling (for 10-12 hours.) In 1 / 2-1% (up to 4%) by the Natron orcler. If boiling is performed under a pressure of 2.5-3 atmospheres, then 2 hours. It happens enough for complete degreased cotton paper. Skipped thus wool often be brought color and therefore exposed to white. It is first rolled with water, centrifuged and is left alone for several days, and then immerses the clock on 6 to the chlorine lime solution (6 kg chlorine Continuation of 1 hour. If the whitening is not complete, the procedure is repeated using the initial solution of chlorine lime. The elevated wool treated in this way is thoroughly washed with water and centrifuged. To remove chlorine and eliminate non-constant colorless connections (often it happens that white color Over time, it takes a yellowish tint again) the waters are lowered into soap water, and then washed with water, acidified with sulfuric acid; The acid further aimed and the cotton is vigorously washed with water, pressed, dried and combed in conclusion. Under the influence of sulfuric acid, after washing the wool in soapy water, the soap decomposition occurs; In the wool fibers, finely crushed stearic acid is deposited, due to which the beautiful white wool is obtained, which crispically crispically produce cristed noise. But this is the last quality, strictly speaking, damages the dignity of surgical wool, which, after degreasing, is again soaked with fatty acid. Therefore, for medical purposes, the wool that was not subjected to washing with a consistent treatment with sulfuric acid. And since in its appointment, the G. Wata should be deprived of all kinds of microorganisms that can be kept in water, then the production of wool should use exclusively boiled water. Production of Wool first were engaged in pharmacists; But now, as a result of great demand for such a product, it is produced on special plants or in lecherous workshops who preparing ordinary cotton, but they are no longer taking off (as for frequency wats), but the best long-fastened cotton varieties (see), with mechanical cleansing All short hairs are removed by the air strengthened air, so that in a benign Mr. Vat should not contain the slightest trace of dust and short fibers. After processing on cards (see cards), the bands of the wool are coagulated and pressed, as for ordinary wool. In the study of the city of Wool should pay major attention to the absence of short fibers and the ability to easily be made water. Link advises, in the study of wool on the content of fatty acids, 20 g watts to extract ether. When evaporation of the latter and drying the residue at 80 ° should be obtained not more than 0.03 g.

Purified cotton wool or cotton paper appears under a microscope, like a crude, consisting of white single-cellular, tubular, for the most part Flat hairs, twisted spiral, inside with a wide flat canal filled with air. Width of fibers \u003d 0.015-0.028 mm. Purified Wat Bela, has no smell, does not contain fat and does not have any action on jets. Compressed between the fingers and thrown into the water, it immediately sinks in the latter, as it is easy and fully wetted with water and watery solutions, which is not typical of the ordinary cotton. When burning, no more than 0.3% ash is obtained, and the aqueous extract is 10 g of watts 20 g of water, evaporated to dryness, should not give any residue. Purified cotton wool and the fabric released from it find medical application In surgery, mainly in the treatment of wounds, ulcers, burns, frostbines, fractures, dislocation, etc.; Next, with rheumatism and various skin sufferings. To the tissues made of purified wool include skimmed: threads, cheese (MULL), English Lint, Cambrick, Square and other fabrics used in the form of bandages, compresses, lumps, etc., both wool and tissues, and tissues Used in surgery part in its pure form, i.e. themselves, part of them are impregnated with various drugs, knitting, coating, fragrant, narcotic, predominantly antickered and disinfectants. Finally, the purified wool is used in pharmacy to obtain colloxylin or collodia used in surgery.
