FIELD: process engineering. ^ SUBSTANCE: invention relates to the method of producing elastically elongating laminate 19 and to laminate produced by proposed method to be used in articles, say, disposable pants. Proposed laminate comprises at least three layers (1, 6, 18). Proposed method comprises the following jobs: a) fabrication of first laminate (8) including first linen (1) of inelastic fibrous nonwoven material and elastic film (6); b) activation of the first laminate (8) by stepwise stretching in at least one direction to impart said first laminate (8) ability of elastic elongation; c) stretching activated first laminate (8) for 10-200% in at least one direction; and d) jointing elongated first laminate (8) by lamination to second linen (18) of inelastic nonwoven materials. ^ EFFECT: elastic elongation, properties of textile, features high extension strength and high puncture resistance. ^ 20 cl, 4 dwg, 1 tbl |
