Definitions

  • the present invention relates to an elastically stretchable nonwoven fabric having a smooth touch to skin and also to a process for making the same.
  • Japanese Patent Application Publication No. 1994-184897 discloses an elastically stretchable web formed by laminating a fibrous layer of elastically stretchable polymer with a fibrous layer of inelastic stretchable polymer.
  • Japanese Patent Application Publication No. 1997-512313 also discloses an elastically stretchable web formed by laminating the fibrous layer of elastically stretchable polymer with the fibrous layer of inelastic stretchable polymer.
  • Japanese Patent Application Publication No. 1992-11021 discloses an elastically stretchable conjugated thread comprising a core-sheath-type conjugated fiber of which the core fiber is made of elastically stretchable urethane and the sheath fiber is made of inelastic stretchable polyamide.
  • Japanese Patent Application Publication No. 1997-316748 discloses an elastically stretchable fabric including a core-sheath-type conjugated filament as a weft.
  • the elastomeric core and the non-elastomeric sheath of the filament are separated from each other and the sheath slackens to form bellows-like wrinkles as the filament is drawn.
  • Japanese Patent Publication No. 3262803 discloses an invention relating to multi-component thermoplastic continuous filaments obtained by melt spinning, a product formed of such filaments and a process for forming such a product.
  • multi-component thermoplastic filaments extruded from the extruder is introduced through a quenching chamber into a Lurgi-duct within which the filaments are drawn and split under the effect of compressed air supplied thereinto.
  • the filaments split in this manner are accumulated on a collecting surface formed by perforated screen or the like.
  • Japanese Patent Application Publication No. 1997-291454 discloses an invention relating to an elastically stretchable nonwoven fabric.
  • the elastically stretchable nonwoven fabric is formed using elastically stretchable conjugated fibers consisting of a hard elastic member comprising crystalline polypropylene as a first component and a thermoplastic elastomer as a second component.
  • the conjugated fibers may be selected from a group including those of various types such as side-by-side and sheath-and-core.
  • Such conjugated fibers can be finished into nonwoven fabric by various processes such as spun bonding and thermal bonding processes.
  • JP 05131580 discloses a stretchable fiber sheet and the manufacture thereof.
  • a composite filament is made up of elastic fibers represent non-elastic fibers, and has a surface area such that the elastic fibers represent preferably 50-75% of the surface area of the composite fiber as a whole.
  • EP-A-1184163 discloses an elastically stretchable composite sheet including an elastically stretchable first web and an inelastically stretchable second web of thermoplastic synthetic resin fiber which is intermittently bonded to the first web, and a process for making the same.
  • the fibrous layer made of elastically stretchable polymer is exposed on the surface of the fabric.
  • the fibers made of such polymer exhibit a relatively high friction coefficient and correspondingly rough touch.
  • the elastically stretchable web or non-woven fabric formed by laminating the fibrous layers tend to be a thick one.
  • the conjugated thread and the fabric disclosed in the above-cited Publication Nos. 1992-11021 and 1997-316748 use the core-sheath type conjugated fiber of which the core is formed by elastomeric fiber and the sheath is formed by non-elastomeric fiber.
  • the sheath functions to cover the elastically stretchable polymer, i.e., the elastomeric fiber and thereby to prevent the elastomeric fiber from coming in direct contact with the user's body.
  • the conjugated thread as well as the fabric disclosed in the above-cited Publications are able to offer a smooth touch to the skin and a comfortable touch for the user's body.
  • the sheath fiber presenting bellows-like wrinkles obstructs the core fiber from elastically contracting and, in consequence, limits an extension coefficient as well as a contraction coefficient of the conjugated thread and the fabric.
  • the conjugated fiber has its sheath formed with the bellows-like wrinkles and therefore it is difficult for these conjugated thread and fabric to offer the soft and flexible touch peculiar to the fiber having a small fineness.
  • the multi-component thermoplastic filaments are split to a plurality of more fine filaments within the Lurgi duct and then formed into a nonwoven fabric.
  • Repective components constituting the multi-component thermoplastic filament appear on the surface of this nonwoven fabric in a form of more fine filaments in accordance with the mixing proportion of these components. If one of the components is a thermoplastic elastomer, the filament of such a thermoplastic elastomer will be exposed on the surface of the nonwoven fabric and a wearer of a wearable article made of the nonwoven fabric may experience a rough touch with poor slip properties of the nonwoven fabric depending on a proportion of the thermoplastic elastomer filament.
  • the elastically stretchable conjugated fiber consisting of the hard elastic member comprising polypropylene as the first component and the thermoplastic elastomer as the second component are intermittently welded into an elastically stretchable nonwoven fabric.
  • the circumferential surface of the conjugated fiber is defined by zones occupied by polypropylene and zones occupied by the elastomer.
  • the thermoplastic elastomer is inevitably exposed on the surface of the nonwoven fabric. Consequently, this nonwoven fabric may have a rough touch and poor slip properties.
  • 1997-291454 describes as one of embodiments a sheath-and-core type conjugated fiber of which the sheath is formed by polypropylene as the first component and the core is formed by the elastomer comprising ethylene- ⁇ -olefin copolymer as the second component.
  • the elastic stretchability of such a conjugated fiber is governed by the stretchability of the hard elastic member comprising polypropylene and the stretchability of the elastomer might be thereby suppressed.
  • the present invention has a first aspect relating to a nonwoven fabric and a second aspect relating to a process for making the nonwoven fabric.
  • an elastically stretchable nonwoven fabric as defined in claim 1.
  • the first aspect of the invention can be implemented in preferable manners as follows:
  • the slip angle is measured in an apparatus depicted by an accompanying drawing, i.e. Fig. 11 .
  • the measuring method of the slip angle is included in the explanation of Fig. 11 .
  • the nonwoven fabric according to the present invention allows the smooth touch of the nonwoven fabric to the article wearer' s skin to be adjusted by placing in the vicinity of each of the elastic fiber at least one inelastic fiber which is longer than the elastic fiber.
  • the smooth touch to the article wearer's skin can be effectively adjusted by placing a plurality of the inelastic fibers in the vicinity of the elastic fiber so as to surround this elastic fiber. Since the segment of the inelastic fiber defined between a pair of the neighboring attaching areas in which the inelastic fiber is inseparably attached to the elastic fiber is longer than the associated segment of the elastic fiber, the elastic stretchability of the elastic fibers as well as the nonwoven fabric is not disturbed by the inelastic fiber.
  • the process according to the present invention for making the nonwoven fabric is primarily characterized in that the conjugated fibers consisting of the elastic fibrous component and the inelastic fibrous component separably attached to the surface of the elastic fibrous component are split into the respective fibrous components so that the inelastic fibers having a smaller fineness may surround the elastic fiber having a larger fineness.
  • the process according to the present invention can provide thin nonwoven fabric which is elastically stretchable and contractible and allows also at least one of the upper and lower surfaces of the nonwoven fabric to present a smooth touch and high slip properties of the inelastic fiber having a smaller fineness instead of those of the elastic fiber having a larger fineness.
  • a substantially hexahedral fragment of nonwoven fabric 1 shown in Fig. 1 in a perspective view has upper and lower surfaces 2, 3 which extend parallel to each other and define the thickness of the nonwoven fabric 1 and side surfaces defined by cut surfaces 4a, 4b, 4c, 4d each intersecting the upper and lower surfaces 2, 3.
  • the nonwoven fabric 1 comprises elastically stretchable fibers 11 made of a first thermoplastic polymer, inelastically stretchable fibers 12 made of a second thermoplastic polymer and conjugated fiber regions 13 formed by the elastic fibers 11 and the inelastic fibers 12 which are joined together side by side.
  • these fibers 11, 12 and the conjugated fiber regions 13 are welded, adhesively bonded or mechanically intertwined together at a plurality of attaching area 16 so that these fibers 11, 12 and the conjugated fiber regions 13 may be substantially fixed in the area 16.
  • the elastic fibers 11 and the inelastic fibers 12 are obtained by splitting each conjugated fiber 13a corresponding to each of the conjugated fiber regions 13 into a fiber component 21 and a fiber component 22 (see Fig. 2 ) during a production process as will be described later.
  • the conjugated fiber regions 13 principally lie in the vicinity of the respective attaching area 16.
  • the elastic fibers 11 have a fineness in a range of 0.1 dtx to 10 dtx and the inelastic fibers 12 have a fineness in a range of 0.05 dtx to 2 dtx.
  • the fineness of the inelastic fiber 12 is preferably smaller than the fineness of the elastic fiber 11. Except for the area 16, in the surrounding area of each of the elastic fibers 11, one to sixteen of the inelastic fibers 12 extends or extend between the neighboring areas 16, for example, the area 16a and the area 16b depicted in Fig. 1 .
  • at least three inelastic fibers 12a, 12b, 12c lie in the surrounding area of the individual elastic fiber 11a (see Fig.
  • the inelastic fibers 12a, 12b, 12c are branched and spaced apart from the elastic fiber 11a.
  • the elastic fiber 11 and the inelastic fibers 12 are repeatedly joined together (at the areas 16) and spaced apart from each other in a longitudinal direction of the elastic fiber 11.
  • each segment of the inelastic fibers 12a, 12b, 12c is longer than the segment of the elastic fiber 11a, and the elastic fiber 11a is substantially rectilinear and the inelastic fibers 12a, 12b, 12c describe various curves, respectively.
  • the ratio of the number of the elastic fiber 11a to the number of the inelastic fibers 12a, 12b, 12c is approximately 1:3.
  • the elastic fiber 11a and the inelastic fibers 12a, 12b, 12c have ends thereof exposed on the cut surface 4a and the number of these ends approximately corresponds to the number of the elastic fibers 11a and the inelastic fibers 12a, 12b, 12c.
  • a ratio of the ends of the elastic fibers 11a to the ends of the inelastic fibers 12a, 12b, 12c exposed on the cut surface 4a is approximately 1:3.
  • the nonwoven fabric 1 can be used for a wearable article, for example, a disposable diaper, disposable pants or a disposable medical gown, and household goods, for example, disposable wipes.
  • a straight distance between the neighboring attaching areas 16a and 16b on the elastic fiber 11a is 0.5 - 10 mm, and that the lengths of the inelastic fibers 12a, 12b, 12c between the neighboring attaching areas 16a and 16b are 1.2 - 5 times of the length of the associated elastic fiber 11a.
  • the elastic fibers 11 are elastically stretched when the nonwoven fabric 1 of the arrangement as has been described above is held with the hands and pulled in a direction A or in a direction B intersecting orthogonally the direction A, whereupon the inelastic fibers 12 are oriented to extend in the direction A or in the direction B.
  • an elastic recovery force of the elastic fibers 11 causes the nonwoven fabric 1 to shrink to the state of Fig. 1 .
  • an elastic material as the elastic fiber 11 has a rubbery rough touch, but the presence of the plural inelastic fibers 12 wrapping around the respective elastic fibers 11 is effective to provide the upper and lower surfaces 2, 3 of the nonwoven fabric 1 with a smooth and slipping touch similar to that of the inelastic fiber 12.
  • the smooth and slipping touch of the nonwoven fabric 1 of the present invention can be controlled by a fineness, a shape of the cross section and a number of the inelastic fiber 12.
  • the fineness of the inelastic fibers 12 may be minimized, for example, in the order of 0.5 dtx to 1.5 dtx to make the touch of the upper and lower surfaces 2, 3 more smooth and flexible.
  • Fig. 2 is a photograph showing cross-sections of conjugated fibers 13a used to make the nonwoven fabric 1 and Fig. 3 is a diagram tracing the conjugated fibers 13a in the photograph of Fig. 2 .
  • a plurality of the conjugated fibers 13a appearing in Fig. 2 are substantially identical one to another.
  • Each of these fibers 13a has a diameter of 25 ⁇ m to 30 ⁇ m and comprises a single elastic fiber component 21 and three inelastic fiber components 22 separably attaching to the surface of the elastic fiber component 21 substantially at regular intervals in a circumferential direction.
  • the conjugated fiber 13a is substantially identical to the conjugated fiber component 13 depicted in Fig. 1 in construction as well as in composition.
  • the conjugated fiber 13a can be obtained by extruding simultaneously an elastic thermoplastic polymer to form the elastic fiber component 21 and an inelastic thermoplastic polymer to form the inelastic fiber component 22 through nozzles of an extruder for melt spinning well known in the art.
  • the elastic fibrous component 21 has on its circumferential surface first curved surface portions 51 each bulging radially outward from an axis of the elastic fibrous component 21 and second surface portions 52 each depressed radially toward the axis of the elastic first fibrous component 21 so that these first and second surface portions 51, 52 alternately appearing in the circumferential direction of the elastic fibrous component 21.
  • the inelastic fibrous component 22 comprises three inelastic fibrous components 22a, 22b, 22c extending in the longitudinal direction of the elastic fibrous component 21 in the grooves 53a, 53b, 53c, respectively.
  • the first polymer to be used to obtain the elastic fiber component 21 includes a thermoplastic polyurethane, a thermoplastic polyurethane containing lubricant and any other thermoplastic elastomers.
  • the second polymer to be used to obtain the inelastic fiber component 22 includes thermoplastic polymer which is incompatible with the first polymer and stretches inelastically.
  • the term "incompatible" used herein means that a conjugation strength of the inelastic fiber component 22 to the elastic fiber component 21 is relatively low and the inelastic fiber component 22 can be easily separated or split from the elastic fiber component 21, when the conjugated fiber 13a is stretched.
