Abstract

Abstract: Absorbent items such as disposable diapers, incontinence pads, nappy handles, training pants, sanitary pants, etc., have a unique waist section that improves the kinetic fit as well as the containment properties of the absorbent. This device includes a collection structure that preferably includes a top layer that is permeable to liquids, a back layer that is impermeable to a liquid, and an absorbent core placed between the top layer and the back layer; Stretch back waist section; Locking system to keep the sorbent on the wearer. The back stretch waistband provides a stretchy core that provides a more comfortable and sticky fit by initially tightening the nappy to the wearer and by continuing this tightness. The stretchy back waist section has a hip section, midsection, and a pair of side straps. The strength/stretch properties of each band are designed to provide this tightness and improved fit. While each section of the stretch waist can be constructed from a number of stretches, it is preferable for straps to include a membrane fabric with a semi-stretch construction. Semi-elastic construction membrane fabric (SELF) exhibits semi-elastic properties in the direction of elongation without the use of additional elastomeric tools. The SELF fabric composition in each part has specific properties to provide the desired strength/stretch properties for each part.

In a flat shape close to the forces involved during wear. As you can see in the drawing; The YY stretch back waist section extends in the same way as described for the LY shape however; Due to the stretchability of the 1871 leg flap sections and the greater stretchability of the ALY front waist section, the front waist area also tends to bulge. so; The Napper 1871 provides an hourglass-type seal without the added and wasted tool required for a Napper 0 hourglass.

Also in this application the “YA absorbent core extends in part from the YA hip portion in Particularly preferred © application; the YA absorbent Gill does not contact the YA hip segment allowing it to "float" in the FA hip segment thus the absorbent core provides stiffness in part of the hip segment to prevent swelling of the hip segment. The stretch YoY preferably has a pentagonal shape as described in US Patent 9,151,097 (Buell et al.).In the application shown in the form of oF oe the stretch front waist portion includes the SELF fabric in Patent Mall where the stretchability of the fabric SELF ve is in a pentagon shape as a result of the curved, non-stretch band shape of the Chad member Backing Part 4107; attaches across a portion of the fabric (SELF) The locking system for the diaper is preferably the double tension fastener system described hereinafter which Provides an angled drawstring around the wearer. EAN

The double tension fastening system includes a primary anchor system and the Ji waist system is preferred. As shown in oY, the 70400 tongue strips of the initial clamping system are regular at an angle to the transverse direction to provide this angled line of clamping. The YoYo Diaper is also equipped with a waist lock system that includes a pair of 1 Yo Yo oY 1st attachment components Wish aligns with the 0047 front stretch waistband to provide tension through the 0 front stretch front waistband and a second connecting component (not shown) Includes part of the upper layer ' 3

The locking system secures the nappy around the wearer during nappy use so that the nappy has a low tendency to loosen/distract and slip/unlock during use. The JE System is designed to create a line or area of tension that causes an encircling force to reach the lumbar curve of the back through the hips to just below the 0|abdominal fold to form a stabilizing function. This line or lines (area) of traction (hereafter the initial line of traction) are placed substantially around the outer border of the wearer's low range of motion to provide stabilizing forces that maintain the position of the nappy during wearing. The initial draw line is best placed at an angle to the horizon on the body of the wearer (at an angle to the transverse direction of the diaper) so that the initial draw line extends from around the lumbar curve (smaller back) over the iliac protrusion of the hips to the front of the wearer; Preferably below the ve belly line. Thus, the initial tension line is placed in the area of the slightest change in the dimensions of the body and a continuous wear situation (that is, the initial tension line is not organized over the swelling of the gluteus maximus muscle, which increases and decreases in its dimensions during movement); So that the initial tension line stabilizes and maintains the fixing forces that keep the diaper position on the wearer, so that the possibility of the diaper slipping or slipping down during the full time of use is reduced as a result of

The movement of the wearer or the force of the extra weight of the diaper when filling it. The angled initial pull line created by the '© Jill System also gives an upward clamping force on the nappy that tends to pull the nappy against the body; thus counteracting the weight force of the loaded nappy; Since the initial tension line has a vector component in the longitudinal direction. The natural clamping force is generated by the prepuce line (another vector component of the angled prepuce line) which stabilizes the absorbent core; In the low motion region since the forces

Natural fixation exerts pressure to push the absorbent core towards the body. Thus, these natural stabilizing forces help maintain the tightness of the diaper as well as reduce leakage due to the fact that the absorbent core remains in a dy relationship with the body. Load angled initial tension line is inclined to reduce the red Tok effects of CEA force uniformity

0 {Fixing in the area of low movement so that the dimensions of the body along the first tensile line do not increase or decrease, which may cause a red 10. Tk because the initial tension line is placed at an angle with the transverse direction to provide its anchoring function; The locking system is designed to provide an angled locking mechanism to ensure that this line gives the initial tension on the nappy. Thus, the locking system may include a number of different clamping systems to provide an angled pretension line. For example; The locking system may simply include a preliminary clamping system. Lock system may fasten and add a portion of the stretchy front waist section; And the; at will; Part of the leg cuff.

In the application shown in Fig. Yo the tongue bar 70460 is attached to profile 7 at an angle to the transverse direction to provide the desired angular initial tension line.

The samples are chosen so that each surface represents a geometric area. (losses) Transition zones 0 should be avoided since they by their nature contain portions of both zones one and two. The measured sample is cut and separated from the intended zone. The 'measured edge' is cut parallel to a particular axis for intended elongation. This axis is usually parallel to the initial axis formed For the first or second zone. A half-inch unstretched specimen is 'measured' perpendicular to the 'measured edge'; while it is attached to the tissue tool; it is then neatly cut and removed from the tissue tool. vo Measure specimens are then placed over the long edge of a glass slide Microspheres. The measured 'SUT' Adal' extends (approximately 1 mm) outward from the edge of the slide. A thin layer of pressure-responsive adhesive is applied to the edge-face of the glass to provide adequate sample support. For highly formed sample areas found It is desirable to gently stretch the sample in its axial direction (without applying appreciable force) at the same time to facilitate contact and bonding of the sample to the edge of the sliding slide.This allows for improved edge identification during image analysis and avoids potentially "wrinkled" edge portions that require additional illustrative analysis. Photographs of each sample as "edge measured" views taken with the reference slide "edge on" using appropriate microscopy measuring instruments of sufficient quality and magnification.
