Abstract

o fecho mecânico inclui uma camada de suporte termoplástica, uma plura-lidade de aberturas na camada de suporte alinhadas em uma primeira direção e que se alterna com uma pluralidade de regiões de fechamento intactas da camada de suporte, e uma pluralidade de elementos de fixação machos. a camada de suporte é plasticamente deformada na primeira direção. as aberturas são mais longas na pri-meira direção do que em uma segunda direção transversal à primeira direção e têm duas extremidades opostas alinhadas na primeira direção. para ao menos algumas das regiões de fechamento intactas entre duas aberturas, a região de fechamento tem uma área intermediária entre as duas aberturas e uma área proximal que toca uma das duas extremidades opostas de uma das duas aberturas, e a área interme-diária tem uma orientação molecular induzida por estiramento maior que a área pro-ximal. o método inclui fender uma camada de suporte termoplástica para formar uma pluralidade de fendas alinhadas na primeira direção que se alterna com a plu-ralidade de regiões de fechamento intactas e, subsequentemente, estirar a camada de suporte.the mechanical closure includes a thermoplastic backing layer, a plurality of openings in the backing layer aligned in a first direction and alternating with a plurality of intact backing regions of the backing layer, and a plurality of male fasteners . The backing layer is plastic deformed in the first direction. the openings are longer in the first direction than in a second direction transverse to the first direction and have two opposite ends aligned in the first direction. for at least some of the intact closure regions between two openings, the closure region has an intermediate area between the two openings and a proximal area that touches one of the two opposite ends of one of the two openings, and the intermediate area has a stretch-induced molecular orientation greater than the proximal area. The method includes splitting a thermoplastic backing layer to form a plurality of slots aligned in the first direction that alternate with the plurality of intact closure regions and subsequently stretching the backing layer.
