摘要:
A method of producing a laminate material includes the steps of providing a first flexible sheet material; providing a second flexible sheet material having a first surface and a second surface, and also having a first width of 1×; stretching the second flexible sheet material in a cross-machine direction to a second width of between about 1.2× and 3× when in a flattened state; necking the second flexible sheet material to produce an accordion shape, thereby reducing the second width of the sheet material to a third width, less than the width of the first width, such that the third width is between 0.65× to 0.975× when in an accordion shape; applying adhesive to the first surface of the second flexible sheet material with a slot coat adhesive process; and joining the first flexible sheet material to the first surface of the second flexible sheet material.

摘要:
Extensible bicomponent fibers and webs particularly adapted for disposable personal care product component applications. Sheath/core configurations providing desirable feel properties for elastic embodiments when compared with conventional elastic fibers and webs are obtained with specific olefin polymer combinations and sheath configurations.
摘要:
Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.

摘要:
A protective garment, such as a surgical gown, includes a garment body defining sleeves. A cuff may be secured at respective ends of the sleeves. An elastic fiber layer is disposed on the sleeves beginning at the sleeve or cuff. The elastic fiber layer has a high friction surface such that an end of a glove pulled over the elastic fiber layer is inhibited from rolling or sliding back over the elastic fiber and down the sleeve. The elastic fiber may be formed of a polyolefin or other polymers according to known processes and may include a dye or colorant that may be used to indicate the fluid protection level of, for example, a surgical gown.

A low density, flexible, resilient, absorbent open-cell thermoplastic foam includes a combination of thermoplastic elastomer, ethylene ionomer, stiff polymer, and surfactant selected to provide various advantageous properties. The foam is useful in personal care absorbent articles, medical absorbent articles, absorbent wiping articles, and a variety of other applications.
摘要:
A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.
