ТЕХНИЧЕСКАЯ ТКАНЬ И СПОСОБ ЕЕ ИЗГОТОВЛЕНИЯ

FIELD: textiles, paper. SUBSTANCE: present invention relates to supporting elements such as tapes or sleeves which are used in production of labelled or textured nonwoven products having a pattern. The supporting element such as tape or sleeve comprises a surface relief pattern on the side which is in contact with the sheet. On the upper surface of the supporting element the contact pads, respective recesses, through cavities and/or grooves are formed to create a surface relief pattern. The contact pads, the respective recesses, the through cavities and/or grooves can be formed by engraving, cutting, etching, stamping, mechanical punching, or their combination. The improved tape or sleeve give the non-woven product manufactured on them the desired physical properties such as bulk density, appearance, texture, absorption capacity, strength and tactile sensations. EFFECT: improved fibre cohesion, reduction of fluffing fibres, improved removal of fabric or its transfer from the specified supporting element to another, or to another position. 45 cl, 15 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (51) МПК D04H 1/44 (13) 2 519 879 C2 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2011108945/12, 04.09.2009 (21)(22) Заявка: (24) Дата начала отсчета срока действия патента: 04.09.2009 Приоритет(ы): (30) Конвенционный приоритет: US US US US 61/096,149; 61/121,998; 61/147,637; 61/147,894 (73) Патентообладатель(и): ОЛБАНИ ИНТЕРНЕШНЛ КОРП.

METHOD FOR MAKING A STABLE WEB HAVING ENHANCED EXTENSIBILITY IN MULTIPLE DIRECTIONS

The present invention provides a stable material having enhanced extensibility and a method for making the same. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.

In the illustrated example a strip 1 (Figs. 1 and 2) of transparent crystalline polypropylene film is stretched in the longitudinal direction at a stretch ratio of 10 : 1 at a temperature of 150‹ C. to a stretched size of 0À5 inch width and 0À002 inch thickness. The strip is then passed in the direction of the arrow A over the face 2 of a jet head 3 at a speed of 100 metres per minute, being pressed against the face 2 by the tensioning rollers 4 and 5. At the same time air at a pressure of 40 p.s.i. is passed into the chamber 6 of the jet head 3 through inlet pipe 7 and emerges from the chamber 6 through two lines of jet holes 8 and 9 in the face 2 as a series of air jets. The holes are 0À005 inch in diameter and are spaced apart in each line by 0À01 inch. As the strip 1 is passed over the lines of holes 8 and 9, the air jets burst through the readily fibrillatable strip to cause the ...

Compacted olefin fibers

A polyolefin plaque is made by hot compaction of an assembly of fibres of the oriented polymer. It has been found to be beneficial to subject the fibres to a prior cross-linking process. Hot compaction is then less temperature-sensitive and produces plaques with excellent hot strength properties. Preferably the fibres have been subjected to prior stages of irradiation and annealing, both in a non-oxidising environment, for example acetylene.

The stabilized extensible necked nonwoven web is easily extended in a direction parallel to the direction necking.

Method of modifying a nonwoven fibrous web for use as component of a disposable absorbent article

An economical method is disclosed for modifying the physical characteristics of a nonwoven fibrous web which involves passing the web between at least one pair of interengaged rolls to incrementally stretch the web, and then withdrawing the incrementally stretched web from between the rolls under tension. A web modified according to the disclosed method has advantageous elongation, extensibility and strength properties, as well as other desirable characteristics. In another aspect, a method is disclosed for forming a composite material by combining a modified nonwoven web with a polymeric film, or an elastic member, which may be liquid impervious yet breathable. In yet other aspect, a method is disclosed for forming a composite material by combining a modified web with a polymeric film which is rendered liquid-impervious yet breathable while the method is performed. The modified nonwoven webs and composite materials made according to the disclosed methods may be advantageously employed in absorbent articles such as disposable diapers.

Method for making a stable nonwoven web having enhanced extensibility in multiple direction

The present invention provides a stable material having enhanced extensibility and a method for making the same. A neckable material is fed in a first direction. The neckable material is subjected to incremental stretching in a direction perpendicular to the first direction. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.

Low density, high loft nonwoven substrates

The present invention relates to a nonwoven substrate suitable for use as a cleaning sheet having density of no more than 0.15 g/cm 3 and comprising at least one fibrous web, said substrate comprising at least one first region and at least one second region wherein said second region comprises protruding elements and is capable of greater geometric deformation than said first region. The present invention also relates to the use of said substrates as cleaning sheets, a process of cleaning soiled surfaces with said substrates and a method of making said substrates.

Method for deforming a web

Methods for forming discrete deformations in web materials are disclosed. In some embodiments, the method involves feeding a web into an apparatus having nips that are formed between intermeshing rolls. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
