[0066] Table 1 shows the effect of three different conditions on the hysteresis properties of the mesh material with the retraction force mechanism: (i) oval mesh itself - "control"; (ii) two layers of oval mesh one on top of the other overlapping each other on top; and (iii) having an oval mesh reinforcing layer at an angle of 30° to the fabric 10.

[0067] The following materials were used to form the samples shown in the table:

[0068] Comparative sample: 1 mil thick, 10:1 L / D holes, 5.5 holes per inch across. so get figure 1 Nested brick pattern with 36% open area shown. Formulation: 86.3% Chevron 4571 high-density polyethylene (HDPE), 5.7% A110313 (TiO 2 concentrate), 3% of P3155 (surfactant concentrate), 5% of Exxon P3155 (PP);

[0069] Sample 1: A comparative sample of two layers adhesively joined with the major axis of the pores in the top layer parallel to the major axis of the pores in the bottom layer.

Abstract

The present invention relates to stretchable webs (10) having a plurality of elongated cells (12), and a retractive force mechanism to provide increased retractive force of the web when stretched in a given direction. The stretchable webs are useful in disposable garments such as diapers, bandages and other hygiene material so that the material fists closely without slipping off.

Description

technical field [0001] The present invention relates generally to stretchable webs, and more particularly to webs made of less elastic materials for use in clothing. The present invention also relates to a laminate comprising the stretchable fabric, wherein the laminate has relatively low elasticity. Background technique [0002] Stretchable fabrics are used in disposable and non-disposable garments to increase garment comfort and fit. The stretchable fabric is used as armbands, belts and other inlays for garments. Stretchable fabrics are used throughout the garment to provide a more comfortable drape throughout the garment. [0003] Stretchable fabrics commonly used in disposable and non-disposable garments include elastic materials. The main disadvantage of elastic materials is the manufacturing cost of such materials. Accordingly, it would be desirable to have a stretchable fabric that is manufactured from low cost materials and yet fulfills the desired variety of use...
