• the second region 66 now contributes as a result of molecular-level deformation in stage II a second resistive force, P2, to further elongation.
• the resistive forces to elongation provide a total resistive force, PT, which is greater than the resistive force depicted in stage I. Accordingly, the general slope of the force-elongation curve in stage II is significantly greater than the general slope of the force-elongation curve in stage I.

• the approximate point at which there is an inflection in the transition zone between stage I and stage II is the percent elongation point of "available stretch".
• the range of available stretch can be varied from about 10% to 100% or more; this range of elongation is often found to be of interest in disposable absorbent articles, and can be largely controlled by the extent to which surface-pathlength L2 in the second region 66 exceeds surface-pathlength Ll in the first region 64 and the properties (composition) of the base film.
• the term available stretch is not intended to apply a limit to the elongation which the web of the present invention may be subjected to as there are applications where elongation beyond the available stretch is desirable.

Furthermore, the resistive force exerted by the SELF web to the applied elongation as depicted in stage I (720a) of curve 720 is significantly less than the resistive force exerted by the base web as depicted in curve 710 within the limits of elongation of stage I. As the SELF web is subjected to further applied elongation and enters stage II (720c) the resistive force exerted by the SELF web increases and approaches the resistive force exerted by the base web.
• the resistive force to the applied elongation for the stage I region (720a) of the SELF web is provided by the molecular-level deformation of the first region of the SELF web and the geometric deformation ofthe second region of the SELF web. This is in contrast to the resistive force to an applied elongation that is provided by the base web depicted in curve 710 of Figure 6, which results from molecular-level deformation of the entire web.
• SELF web materials of the present invention can be designed to yield virtually any resistive force in stage I which is less than that of the base web material by adjusting the percentage of the web surface which is comprised of the first and second regions, respectively.

• the absorbent layer 20 may comprise an additive such as lotion, surfactant, alcohol, water, perfume, anti-perspirant, medicine, cleaning agents, bleach or any mixture of these.
• the back panel 22 of the mitt 15 is differentially extensible and preferably comprises a structural elastic-like film (SELF) web.
• the differential extensibility provided by the SELF back panel 22 allows a range of hand sizes to fit comfortably within the mitt 15.
• differential extensibility to fit varying sized hands can be accomplished by various elastic-like materials, composite materials that produce elastic-like characteristics and/or processes to make a material(s) more elastic-like.
• the back panel 22 of the mitt 15 is of the same construction as the back panel 170 of the glove 10.
• Other embodiments are contemplated using the aforementioned panels for the construction of a mitt with or without a thumb covering.
• a wearer of the mitt 15 inserts a hand into the hollow interior through the provided opening 55 wherein the back panel 22 contacts the back of the wearer's hand and the inner surface 35 of the front panel 21 contacts the wearer's palm, and thereafter properly positions the absorbent layer 20 for cleaning, wiping and/or absorbing.
• the mitt can be everted by making a fist with the mitt-hand, pulling the structure over the fist from the back edge 40 of the mitt 15.
• the layers are transposed, and the inner surface 35 of the front panel 21 and the inner surface 33 of the back panel 22 become the outer surfaces of the now waste article. More simply stated, the mitt is turned inside out after its use and then thrown away.
• the hand of the wearer Upon use, the hand of the wearer is protected against waste products of various contacted surfaces as the hand contacts only the interior surfaces of the inner layers which are water-repellent and water-proof.
• the hand When contact with a surface has been completed, or when the mitt 15 has become saturated, it is turned inside out, whereby the inner surfaces 33 and 35 become the outer surfaces, and the outer surfaces 32 and 34 become the inner surfaces. That is, the wearer makes a fist, and with his or her other hand, grasps a point on the back edge 40 and carefully pulls the fisted hand toward the open mouth of the mitt 15, until the entire end of the mitt 15 is pulled through the opening 55.
