Claims (11)
1. Экструзионный слоистый материал (8) из нетканого волокнистого полотна и термопластичной пленки, содержащий нетканое волокнистое полотно (12) и термопластичную пленку (3), нанесенную посредством экструзии на одну поверхность полотна (12) с концами волокон, выступающими наружу из поверхностей полотна и входящими внутрь пленки (3) для соединения полотна (12) с пленкой (3) без образования сквозных отверстий в пленке (3), отличающийся тем, что полотно (9) снабжено множеством выступающих наружу от обеих поверхностей полотна концов волокон, образованных посредством вытяжки волокнистого полотна (12), по существу равномерно по ширине и толщине полотна (12), причем другая поверхность (9) полотна содержит множество концов волокон, проходящих наружу, для обеспечения мягкой волокнистой структуры всего слоистого материала (8).
2. Способ экструзионного ламинирования нетканого волокнистого полотна термопластичной пленкой, включающий подачу нетканого волокнистого полотна (12) в щель между парой валиков (4, 5) для экструзионного ламинирования термопластичной пленкой (3), выдавливание термопластичного экструдата в щель между валиками при температуре выше точки размягчения экструдата для образования пленки (3), и управление усилием сжатия между волокнистым полотном (12) и экструдатом в щели между валиками для соединения одной поверхности полотна (12) с концами волокон, выступающими наружу от поверхностей полотна и входящими внутрь пленки (3) для соединения полотна с пленкой без образования сквозных отверстий, отличающийся тем, что перед вводом полотна (12) в щель полотно (12) подвергают вытяжке по существу равномерно по ширине полотна (12) и по его толщине, для обеспечения множества концов волокон, проходящих наружу от обеих поверхностей полотна, при этом усилия сжатия контролируют для сохранения множества проходящих концов волокна на наружной поверхности волокнистого полотна (9) для обеспечения мягкой волокнистой структуры всего слоистого материала (8).
3. Способ по п. 2, отличающийся тем, что последовательные вытяжку и экструзионное ламинирование выполняют со скоростью 2,5 - 5,0 м/с.
4. Слоистый материал по п.1, или способ по п.2 или 3, отличающийся тем, что полотно (9) содержит полиолефиновые волокна.
5. Слоистый материал по п.1 или 4, или способ по пп.2 - 4, отличающийся тем, что термопластичная пленка выполнена из полиолефина.
6. Слоистый материал по п.1, или способ по п.2 или 3, отличающийся тем, что волокна выполнены из полипропилена, полиэтилена, полиэфиров, целлюлозы, вискозы или нейлона, или смесей двух или большего количества таких волокон.
7. Слоистый материал по п.1 или 6, или способ по п.2, 3 или 6, отличающийся тем, что термопластичная пленка выполнена из полиэтилена или полипропилена или сополимеров на основе указанных соединений.
8. Слоистый материал по п.1, или способ по п.2 или 3, отличающийся тем, что полотно (9) и пленка (3) выполнены из биоразрушаемых полимеров.
9. Слоистый материал или способ по п.8, отличающийся тем, что в качестве биоразрушаемого полимера использован поливиниловый спирт, поликапролактон или полимер на основе крахмала, или смеси указанных соединений.
10. Слоистый материал по пп.1, или 4 - 9, или способ по пп.2 - 9, отличающийся тем, что волокнистое полотно (9) имеет удельный вес 6 - 85 г/м2, а термопластичная пленка (3) имеет толщину пленки от 6,4 до 200 мкм.
11. Слоистый материал по пп.1, или 4 - 10, или способ по пп.2 - 10, отличающийся тем, что полотно (9) выполнено из штапельных или крученых волокон.
