Alternative methods for the wool wax extraction from wool scouring wastes

Abstract: Métodos alternativos para la extracción de la cera de lana contenida en efluentes residuales generados tras lavados industriales de lana.Las fibras de lana, tras obtenerlas de las ovejas y antes de ser procesadas industrialmente, han de ser lavadas. Este proceso genera residuos altamente contaminantes que pueden obtenerse en dos formas diferentes, una fase líquida y una fase sólida. Ambas fases contienen, entre otros, una gran cantidad de la grasa generada por las ovejas y que se puede recuperar y purificar pa… Show more

“…Neoseiulus californicus did not lay any eggs inside the organic wool. The lanolin grease present in the organic wool is secreted by the sebaceous glands of wool-bearing animals (López-Mesas, M., Carrillo, F., Guttiérrez, M. C., & Crespio, M., 2007) and it produces a specific odour (Lisovac & Shooter, 2003) which may repel arthropods.…”

“…It was found that suint is secreted from sweat glands of the sheep and dries on the skin and wool fibre. Suint is very water-soluble and can be withdrawn from the native wool by extraction in aqueous medium [2,3].…”

“…Fats and oils constitute the main components of wool wax [5], excreted from the sebaceous gland attached to the root of each wool fibre in the basal sheet of the sheep's skin and gathers inside the wool fibre while it grows [2,6,7]. This lubricant protects the wool from the effect of weathering such as sun, wind and rain.…”

“…К современным способам ускорения экстракции относят различные физические и физико-химические методы воздействия. Известно использование электромагнитного поля сверхвысокой частоты [11], ультразвуковых пульсаций [12], вихревой экстракции с высокой частотой вращения мешалки [13], микроволнового электромагнитного излучения [14][15][16], сверхкритического диоксида углерода [17,18], электрического поля постоянного тока [19,20].…”
