Номер: RU2331724C2

Изобретение относится к способу изготовления композиционного нетканого материала, а также к установке для его изготовления. Способ изготовления композиционного нетканого материала, состоящего из двух слоев соответственно: нижнего слоя, содержащего длинные искусственные и/или синтетические волокна, длина которых составляет 15-80 мм и верхнего слоя, содержащего короткие натуральные волокна, длина которых составляет 0,5-8,0 мм. В оперативном режиме способ включает следующие этапы: диспергирование, прежде всего, натуральных волокон в воде; нанесение водной дисперсии, полученной таким образом, на прочес нижнего слоя, который здесь же формируют или который уже был сформирован ранее; удаление избытка воды сквозь нижний слой; перепутывание волокон верхнего слоя с волокнами нижнего слоя посредством воздействия струями воды; и, наконец, сушку и накатку в рулон полученного композиционного нетканого материала. Технический результат заявленного изобретения заключается в снижении стоимости изготовления ...

A method of making a non-woven fabric comprises forming a laminated structure consisting of an assembly of relatively loosely associated fibres and a discrete thermoplastic sheet in surface contact therewith, needle-punching the laminated structure and then agglutinating the thermoplastic sheet thereby clamping in position the needle-punched fibres through adhesive bonding between the fibres and the sheet. In a modification of the process a plastic sheet is laminated to two surface fibrous layers. Agglutination of the plastic sheet may be effected by heating or by the application thereto of solvents or swelling agents. Specified fibres are cotton, silk, wool, cellulose esters, polyamides, polyesters, polyhydrocarbon and acrylic fibres and blends thereof. Specified thermoplastic sheets are regenerated cellulose, cellulose esters, polyethylene, polypropylene, polyesters, polyamides ...

A fabric comprising a plurality of textile fibres, wherein said plurality of fibres comprises fibres that have been selected from two groups of fibres. The first group of fibres comprises multiple fibres having a first average length, and the second group of fibres comprises multiple fibres having a second average length, the first average length being shorter than the second average length. Further, the fibres of the first group have a first length variance being greater than a second length variance of the fibres of the second group. Thereby, the elongation properties of the fabric is changed in respect of the cross direction of the fabric, whilst maintaining almost unchanged strength in the longitudinal direction at a low basis weight. The elongation properties include a controlled reduction in the cross-directional tensile strength and a corresponding increase in cross-directional elongation, whilst still providing enough cover and longitudinal direction strength for the material to be made and formed in industrial processes. Thus, the extension profile may be said to be engineered when using fibres of different average lengths in a fabric as disclosed. Further, the possibility of controlling the average lengths of fibres through the right selection of groups of fibres provides a possibility of engineering the strength in detail. More specifically, according to the present invention, a weakness is engineered in the cross direction, whereby the maximum elongation length in said cross direction is increased compared to a conventional and comparable fabric not comprising groups of fibres selected according to the invention.
