HYDRAULICALLY ENTANGLED NONWOVEN FABRIC WITH HIGH WEB STRENGTH

HYDRAULICALLY ENTANGLED NONWOVEN FABRIC WITH HIGH WEB STRENGTH A web of gray cotton fibers is entangled by passing it under a series of low pressure liquid nozzles or jets which are oscillated in a direction transverse to the direction of travel of the web. The entangled web is then subjected to a cotton scouring step, and then dried, to produce a strong coherent nonwoven fabric that requirres no resin binder and has a high capacity for water. Particular parameters of liquid pressure, frequency and amplitude of oscillation of the nozzles or jets and energy transferred from the jets to the fibers have to be maintained. The nonwoven fabric thus produced comprises at least a major proportion of cotton fibers, is free of natural oils, waxes, and synthetic resin binders, and has a tensile strength which is at least as great for the wet fabric as for the dry fabric in both the lengthwise and cross directions.

A method is described for forming reconstituted leather sheet material from a mixture of base fibres, such as leather fibres, and bi-component synthetic fibres which have outer layers which melt at a lower temperature than their inner cores. The fibres are mixed, formed into a web and then heated so that the synthetic fibres fuse together to form a network within the web. The base fibres are then tangled, whilst constrained by the network, preferably using hydroentanglement. A high quality reconstituted leather sheet material is thus produced. 1. A reconstituted leather sheet material having a leather-like feel , the reconstituted leather sheet material being formed by a method comprising the steps of:evenly distributing and compressing a mixture of predominantly waste leather base fibres and additional synthetic fibres to form a web, wherein the additional synthetic fibres have meltable surface layers and the base waste leather fibres comprise leather fibres having fibrillated branches,heating the web to melt the surface layers of the additional synthetic fibres so as to cause such fibres to fuse together at intersections to form fused network intersections within the web mixture, andsubjecting the web mixture to successive hydroentanglement stages to entangle the waste leather fibres with each other while initially constrained by the network, such that the increase in tensile strength arising from the hydroentanglement of the fibers within the web is greater than the tensile strength of the web prior to hydroentanglement.2.

Nonwoven webs having improved necking uniformity

A neckable nonwoven web is provided with a central region and two edge regions, the central region being selectively easier to neck than the two edge regions. The nonwoven fibers in the central region have a polymer composition and/or physical properties which differ from the nonwoven fibers in the two edge regions.

Hydroentangle polyolefin web

본 발명은 연속 폴리올레핀 필라멘트 섬유를 수압교락시켜 직물 웹을 형성시키는 방법에 관한 것이다. 섬유를 60 내지 150 메쉬 스크린 상에 지지시키고 2000psi 이상으로 작동하며 0.7MJ-N/Kg 이상의 총 충격 에너지를 제공하는 고압워터 제트하에 통과시켜 섬유를 교락시킨다. 바람직하게는, 수압교락된 웹을 이후에 300 내지 1200psi의 압력으로 작동하는 미세한 가공 워터 제트하에 통과시켜 섬유를 재분포시킨다. 경우에 따라, 가공제를 교락된 웹에 가할 수 있다. 수득한 수압교락된 웹은 가시 균일도, 불투명도, 유연도, 안락감, 강도 및 차단특성이 선행기술의 웹보다 상당히 증가되기 때문에 1회용 산업용 의류를 제고하는데 특히 유용하다. The present invention relates to a method of hydraulically entanglement of continuous polyolefin filament fibers to form a woven web. The fibers are entangled by supporting the fibers on a 60-150 mesh screen and running under a high pressure water jet that operates above 2000 psi and provides a total impact energy of at least 0.7 MJ-N / Kg. Preferably, the hydroentangled web is then passed under a finely processed water jet operating at a pressure of 300 to 1200 psi to redistribute the fibers. If desired, a processing agent may be added to the entangled web. The hydraulically entangled webs obtained are particularly useful for improving disposable industrial garments because the visible uniformity, opacity, softness, comfort, strength and barrier properties are significantly increased over prior art webs.

Способ изготовления композитного нетканого тонколистового материала, включающий: - экструзию непрерывных волокон из фильеры; - вытягивание волокон через щелевой вытягивающий блок в тонкие непрерывные волокна; - формование полотна из нескрепленных непрерывных волокон без термических соединений в процессе укладки волокон; - гидросплетение полотна, включающего непрерывные спряденные волокна вместе с формованными влажным или пенным способом короткими волокнами, содержащими натуральные и/или синтетические волокна или штапельные волокна, для интеграции и механического соединения и формования термически нескрепленного композитного нетканого тонколистового материала; отличающийся тем, что создается влажная среда при формовании и укладке непрерывных волокон на стадиях укладки волокон на уже смоченную поверхность, причем сохраняется ширина выпуска щелевого вытягивающего блока, открытого более чем на 65 мм, и добавляется жидкость на выпуске щелевого вытягивающего блока. 2. Способ по пункту 1, отличающийся тем, что сохраняется ширина выпуска щелевого вытягивающего блока, открытого более чем на 70 мм и предпочтительно более чем на 75 мм. 3. Способ по пункту 1 или 2, отличающийся тем, что непрерывные волокна имеют Стр.: 1 A 2 0 1 5 1 3 0 5 9 9 A Адрес для переписки: 129090, Москва, ул. Б. Спасская, 25, стр. 3, ООО "Юридическая фирма ...
