Summary
An original technology of commercial production of antimicrobial polyethylene terephthalate (PET) fibres on standard equipment.
Description
Adding antimicrobial polyethylene terephthalate (PET) fibres in the yarn on the basis of cotton, wool, silk, provides textiles with a capacity of suppressing growth of bacteria and fungi, along with inherent durability of PET fibres and creasing resistance. The technology is based on the occurrence of a system of branching micropore (crazes) in the structure of fibres, which have undergone orientational elongation. Orientational elongation of fibres is carried out in a modifying solution containing organic and non-organic anti-microbial components. Modifier particles penetrating into crazes settle in them. Prolonged secretion of the modifier ensures stable antimicrobial activity of fibres. Fibres with such properties and corresponding yarn are resistant to pathogens after repeated washing, and compare well with traditional textile materials performance.
