FIELD: textile, paper. ^ SUBSTANCE: method of making cotton pads, consisting in the fact that compacted bleached cotton is opened, and cotton linens are made from it, sent to belt conveyor laid one onto another. Afterwards they are fixed to each other with the help of water jets supplied under pressure at linens at both sides, and then fixed linen is dried, and afterwards punches are used to cut cotton pads out of it. At the same time inner layers of cotton linen are made of secondary raw materials that remains after cutting of cotton pads, for which purpose it is separated into fibres, and cotton linens are fixed to each other in two stages - first by water jets under pressure of 0.1-6 MPa, and then by water jets under pressure of 1-15 MPa. ^ EFFECT: increased coefficient of raw materials use in production of cotton pads. ^ 2 cl |
