NONWOVEN TEXTILES WITH MEDICAL DESTINATION ROMANIAN PRODUCTION

Abstract

The widest range of medical disposable from nonwoven textiles are: absorbent and hygiene products : (diapers, feminine care, incontinence) from the layered structures absorbent or impervious; use products such as hospital operating theaters sterile clothing (caps, gowns, masks, shoe coverings), materials for field operators, lab coats, packaging materials for hot or cold treatments, sterile materials (wipes, bandages, sterile bandages, etc.). Currently these materials, in their majority, are imported. This paper presents research done for getting, with the country equipment, disposable medical products from 40 g/m2 nonwoven textile materials. The technology adopted for the purpose, in SC "Minet" S.A. Ramnicu Valcea, Romania consisted of the following steps:Carding - folding, the aggregate Spinnbau-Hergeth type, Germany, with major changes carding technology adjustment and folding, to obtain a fibrous layer with a mass per unit surface of about 40-50 g / m2 and a width of 2,1 m;Pre-heat consolidation by pre-heating required only to ensure product stability required minimal interphase transport to final consolidation. Final thermal consolidation of the fibrous layer by thermal calendering at a temperature of 110°C and calenders cylinder speed of 2 m / min. The processing of the fiber by carding - folding and preliminary thermally consolidation and final by calendering.
