LIQUID ABSORBING SHEET MATERIAL, METHOD OF MANUFACTURING THE LIQUID ABSORBING SHEET MATERIAL, METHOD OF MANUFACTURING A SHEET MATERIAL AND SANITARY ARTICLES MADE THEREOF.

摘要

A METHOD OF PREPARING TWO-LAYER SHEET COMPRISES SPRAYING HEAT FUSIBLE POLYMER ON FABRIC BASE MATERIAL SURFACE IN A SHAPE OF A SHEET DURING CONSECUTIVE TRANSPORTATION OF THE SHEET FABRIC BASE MATERIAL SO AS TO FORM A SECOND FABRIC BASE LAYER.AND ALSO A METHOD OF PREPARING LIQUID ABSORBING SHEET MATERIAL COMPRISES SPRYING FIBROUS BODY MADE OF LIQUID CONVEYABLE MATERIAL ON THE SECOND FABRIC BASE LAYER AND HAVING THE LIQUID CONVEYABLE MATERIAL INVADE INTO BOTH TISSUE ORGANIZATION OF THE TWO-LAYER. IT IS POSSIBLE TO INTRODUCE LIQUID SO AS TO PERMEATE FROM A SURFACE TO REVERSE SIDE WITHOUT DETERIORATION OF LIQUID-PERMEABILITY IN THUS OBTAINED LIQUID ABSORBING SHEET MATERIAL BECAUSE FIBROUS BODY AS LIQUID CONVEYABLE MATERIAL TO THE SURFACE IS SCATTERED EXTENDING FROM THE REVERSE SIDE IN BOTH TISSUE ORGANIZATION. MOREOVER, THE SURFACE OF THE LIQUID ABSORBING SHEET MATERIAL MAINTAINS DRY STATE.
