Development of membrane type knitwear materials

Work it is carried out research of eight variants of knitted materials membrane the type, produced of polypropylene and polyester complex strings and cottonpolyester yarn. The estimation of quality of cloths is lead on parameters: superficial density, thickness, durability, an extensibility, air- and water permeability, water-absorbability and wettability. By results of rank a complex estimation of quality the optimum variant is certain. The chosen variant of a cloth is offered for manufacturing filters. The made filters are transferred for carrying out of tests.
