PRESSED PRODUCT IN WET CONDITION IN FORM OF TOILET PAPER AND TOWELS WITH INCREASED COEFFICIENT OF ELONGATION IN CROSS-SECTION DIRECTION AND LOW STRENGTH RATIO VALUE, MADE WITH APPLICATION OF CREPING PROCESS ON TISSUE AT HIGH SOLID SUBSTANCE CONTENT

摘要

FIELD: medicine.;SUBSTANCE: absorbing cloth from a cellulose fiber contains an admixture of hard wood and soft wood fibers located in the form of mesh structure, including: the set of columnar areas fibers conglomeration with relatively high local density, aggregated by means of set of the connecting areas with lower local density, where orientation of fibers is inclined along a longitudinal direction between the columnar areas interconnected in a such way, where the cloth possesses coefficient of elongation in a cross-section direction, which is at least in 2.75 times higher than relative strength at cloth stretching in a dry condition. The above-stated material is obtained as follows. A water cellulose composition from hard wood fibers is prepared. The composition is moved on a forming tissue in the form of a stream which is let out from a pressure head box with a flow rate. The composition is dehydrated and compacted for manufacturing of a paper for formation of the fibrous layer possessing chaotic distribution of a fiber for paper manufacturing. Packing of the dehydrated fibrous layer possessing chaotic distribution of a fiber on the transporting transferring surface moving with the first rate. Creping of a fibrous layer from the transferring surface on a tape at dryness from 30% to 60% with use of the pattern creping tape. The creping stage is carried out under pressure in a contact zone of the creping tape confined between the transferring surface and the creping tape. Thus the tape is moved with the second speed, lower than speed of the transferring surface. Tape drawing, parametres of a contact zone, speed difference and dryness of the fibrous layer are chosen in such way to crepe the fibrous layer at its removal from the transferring surface and to redistribute on the creping tape with formation of a fibrous layer with mesh structure. Drying of the fibrous layer is performed after. The process is regulated so that coefficient of elongation in a cross-section direction is, at least, approximately in 2.75 times higher than relative strength at stretching of the fibrous layer in a dry condition. Such method allows obtaining a cellulose fibrous layer for products made from thin paper, and also products in the form of towels.;EFFECT: improvement of ready product quality and power consumption decrease.;33 cl, 10 dwg, 22 tbl
