Cotton And Linen Based Wound DressingsLint:Lint was a common medical product which was used to dress wounds.Flax, but more generally, linen scraped into a soft substance, and used for dressing wounds and sores. Websters Dictionary, 1861.A soft material for dressing wounds, prepared by ravelling or scraping linen cloth. Oxford English Dictionary.

Cotton And Linen Based Wound DressingsLint.Lint is also known as charpie.Charpie is defined as Old linen unravelled into short ends of thread for surgical dressings; very narrow, thread-like strips of linen torn off so as to leave fringed ends.Cotton And Linen Based Wound DressingsManufacturing of Lint:Lint is a soft, delicate tissue or mass, prepared in two ways, in one of which the transverse threads of soft, old linen are drawn out by a machine, leaving the longitudinal ones covered by a sort of tomentum or cotton-like mass; whilst the other, the cotton-like surface is produced by scraping with a sharp knife a similar piece of cloth previously fastened to some firm substance.Cotton And Linen Based Wound DressingsManufacturing of Charpie:It is made by collecting the threads torn from pieces of linen, four to five inches square, such as is used in patent lint. The process, however, goes a step farther than that for making lint, and tears the threads entirely apart instead of preserving the cloth.

Cotton And Linen Based Wound DressingsCharpie is usually divided into two kinds, according to the length and fineness of the thread composing it; that which is long and coarse being employed to keep open the sinus, fistulae, and to act as an outer dressing; while the softer, finer kind is placed in immediate contact with the wound.Cotton And Linen Based Wound DressingsUse of Lint or Charpie:Charpie was mainly used for absorption of drainage and was used to pack in wounds and then covered with a mixture of wax, rosin, white lead and other substances that would block out air to the wound. Even though it adhered to the wound, when the dressing was changed and the mass was pulled away, only the dead matter adhered to the dressing and the healthy area was not affected.Cotton And Linen Based Wound DressingsCotton Wool Balls:Soft and highly absorbent Quality cotton wool.Made from 100% pure cotton.Gentle to the skin.Ideal for general skin cleansing, topical swabbing and pre-operative skin preparation.

Flax BandagesHistory of FlaxSince ancient times, flax has been known to be a source of oil and fibres, and it has been cultivated as a dual-purpose plant for a long time. Nowadays, it is a multi-purpose plant and its exploitation is not restricted to the production of linen fibre and oil. Actually, whole plant exploitation is possible,Flax is composed ofFlax is a good source of unsaturated fatty acids, dietary fibre and another nutrients. It is composed mainly of fat (41%), protein (20%) and dietary fibre (28%). The contents may vary depending on genetics, environment, seed processing and the analysis method.Polyunsaturated fatty acids compose about 73% of the total fatty acid contentSignificanceFlan fibers areflexible,lustrous and soft.Comments by Great ScientistsFlax has great possibilities. But traditional flax doesnt have that effect. It has to be innovative, created by biotechnological methods, with a specific aim, modified to result in a proper product, said Genetic Biochemist Dr. Jan Szopa-Skorski.Comments by Great Scientistsan anti-infection oil that could be used in arteriosclerosis treatment and a product for cancer treatmentSzopa-Skorski.An ExperimentUse of Flax by boosted antioxidant compounds in the plants to improve regrowth of skin cells, which can proliferate in the cavity of a wound.
