Abstract
Abstract A glove comprising two elastic sheet materials, at least one of which consists essentially of a selected elastic polyurethane nonwoven fabric, in particular, relatively thin, is elastic, air and moisture permeable, dimensionally and texturally stable, nonslip and dustproof. It comfortably fits on the hand, substantially allowing fingers to move freely and retaining an exquisite sense of touch, and is particularly useful as a work or sport glove for slip-prevention and/or dustproofing purposes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
50 words
A glove comprised of two elastic polyurethane sheets, at least one of which consists essentially of an elastic polyurethane fiber, nonwoven, air-permeable fabric, said two sheets being heat sealed together along the periphery thereof to form a configuration corresponding to the contour of a hand, leaving the wrist portion unsealed.
Claim 2
Dependent Claim
50 words
A glove comprised of two elastic polyurethane sheets, at least one of which consists essentially of an elastic polyurethane fiber, nonwoven, air-permeable fabric, said two sheets being heat sealed together along the periphery thereof to form a configuration corresponding to the contour of a hand, leaving the wrist portion unsealed.
Claim 3
Dependent Claim
18 words
A glove as claimed in claim 1 wherein both of said sheets comprise an elastic polyurethane nonwoven fabric.
Claim 4
Dependent Claim
29 words
A glove as claimed in claim 1 wherein at least one of said two sheets comprises a laminate of an elastic polyurethane nonwoven fabric and an elastic polyurethane film.
Claim 5
Dependent Claim
25 words
A glove as claimed in claim 1 wherein one of said sheets comprises an elastic polyurethane nonwoven fabric and the other an elastic polyurethane film.
Claim 6
Dependent Claim
75 words
A glove as claimed in claim 1, claim 2, claim 3 or claim 4 wherein said elastic polyurethane nonwoven fabric has a weight of 50-150 g/m 2 and an air permeability of at least 10 cc/cm 2 /sec. and comprises filaments each having an average diameter of approximately 50 microns or less, said filaments being disposed in random, overlapping relationship and being substantially heat bonded together at the cross-contact points thereof in said nonwoven fabric.
Claim 7
Dependent Claim
53 words
A glove as claimed in claim 5 wherein said nonwoven fabric exhibits an elongation at break of 300-800%, a breaking strength of 0.4-1.2 kg/cm, an elastic recovery percentage of 100% elongation of at least 85%, an elastic recovery percentage of 50% elongation of at least 90% and a bending resistance of 20-50 mm.
Claim 8
Dependent Claim
24 words
A glove as claimed in claim 5 wherein said average diameter of a single filament of said nonwoven fabric is 30 microns or less.
Claim 9
Dependent Claim
24 words
A glove as claimed in claim 3 or 4 wherein said film has a moisture permeability of at least 1,500 g/m 2 ·24 hr.
Claim 10
Dependent Claim
19 words
A glove as claimed in claim 8 wherein said moisture permeability is at least 2,000 g/m 2 ·24 hr.
Claim 11
Dependent Claim
35 words
The glove claimed in claim 8 wherein the said film exhibits a breaking strength of 1.0-20.0 kg/cm, an elongation at break of 300-900% and an elastic recovery percentage of 50% elongation of at least 90%.
Claim 12
Dependent Claim
33 words
A glove as claimed in claim 1 wherein at least one of said sheets has an embossed pattern on the surface thereof to promote the abrasion resistance, dustproofness and grip of said glove.
Claim 13
Dependent Claim
18 words
A glove as claimed in claim 11 wherein at least one of said sheets has an antistatic property.
Claim 14
Dependent Claim
22 words
A glove as claimed in claim 1 wherein said fabric contains from about 0.05 to about 5 wt.% of electrically conductive fibers.
Claim 15
Dependent Claim
175 words
A glove comprised of two elastic polyurethane sheets, at least one of said sheets consisting essentially of an air-permeable, nonwoven fabric made of elastic polyurethane filaments and having a weight (x) of 50 to 150 g/m 2 , said nonwoven fabric consisting essentially of a multiplicity of substantially continuous, individual, polyurethane filaments disposed in randomly overlapping relationship to each other and bonded to each other at the points where they cross each other, said filaments having an average diameter of 30 microns or less, said nonwoven fabric having an elongation at break of 300 to 800%, a breaking strength of from 1.4 to 1.2 kg/cm, an elastic recovery percentage of at least 85% from 100% elongation and at least 90% from 50% elongation, an air permeability of at least 10 cc/cm 2 /sec. and a bending resistance (y) in the range of 20 to 50 mm, wherein y<0.2x+30, said two sheets being heat sealed together along the periphery thereof to form a configuration corresponding to the contour of a hand, leaving the wrist portion unsealed.
Claim 16
Dependent Claim
175 words
