METHOD OF WET WASHING TO PRODUCE BIOCIDE TEXTILES

摘要

The method of furnishing fabric during washing, which comprise of preliminary washing, essential washing, water rinsing with further water removal, and then neutralization and/or starching, and/or softening, final centrifugation and drying, wet or dry pressing, characteristic of that during softening step and/or after centrifuging step the fabric is treated with specimen containing nanoparicles of copper and copper(II) oxide and/or other compounds of copper(II) of 20- 50 nm diameter average size, or with specimen containing nanoparicles of copper and copper(II) oxide and/or other compounds of copper(II) of 20- 50 nm diameter average size as well as nanoparticles of silver and silver(I) oxide and/or other compounds of silver(I) of 20- 50 nm diameter average size, the weight ratio of metals being between 10: 1 and 1 : 10, the copper nanoparticles or silver and copper nanoparticles are introduced in such a way which ensures the final amount of 10 - 1000 mg of copper or copper and silver per 1 kg of dry fabric; furthermore at the softening step the known softener is introduced into washing bathwater and after the centrifuging step the refiner is introduced, followed by water removal and afterwards the nanoparticles of copper or copper and silver and their oxides are stabilized on fabric surface by exposing the fabric to high temperature during dry or wet pressing (ironing or mangling).
