INTERNATIONAL PCT APPLICATION
Title of Invention
PROTECTIVE GLOVE WITH ENHANCED EXTERIOR SECTIONS
Cross Reference to Related Applications
[0001] This application claims priority to U.S. Patent Application No. 14/657,081 , filed March 13, 2015, and U.S. Patent Application No. 14/296,612, filed June 5, 2014. All of said applications are incorporated herein by reference.
Technical Field and Background of the Invention
[0002] The present invention relates to fabric articles, such as gloves with sections having enhanced properties formed on the exterior surface of the glove. The enhanced sections can be areas on the exterior surface of the glove having superior physical properties, such as cut or abrasion resistance, in relation to the other parts of the glove.
[0003] Often it is desirable for a single glove to be constructed of various sections having distinct properties. For example, safety gloves often have an interior surface layer comprised of a relatively soft yarn for the comfort of the wearer, and an exterior surface comprised of a relatively rough yarn providing cut resistance. Plaiting (also known as "plating") is a process that has been used to make such gloves. Plaiting is a process in which the fabric is produced from two yarns having different properties or characteristics. A primary yarn is placed on the outside (or face) of the fabric, and the plaiting yarn is placed on the inside (or back) of the fabric. [0004] Prior art gloves constructed of plaited fabrics have required the yarn with enhanced properties to be plaited to the inside (back) of the fabric. When it is desirable because of cosmetic or functional requirements for the plaiting yarn to be on the outside of the glove, the glove must be inverted (turned inside out). Inverting is a separate, time-consuming operation done manually or on a special machine.

Description of Preferred Embodiments of the Invention and Best Mode
[0048] A protective glove according to a preferred embodiment of the invention is illustrated in Figures 1 -6, and shown generally at reference numeral 10. The glove 10 is comprised of an inner primary yarn 1 1 , and a plaiting yarn 21 having cut resistance properties plaited to the primary yarn 1 1 . The inner primary yarn 1 1 can be comprised of a first core strand 12 of 450 (one hundred denier) fiberglass and a second core strand 14 comprised of four hundred denier ultra-high molecular weight polyethylene (UHMWPE), a first covering strand 1 6 of one-hundred fifty denier textured polyester wrapped around the core stands 12, 14, and a second covering strand 18 of one- hundred fifty denier textured polyester wrapped over the first cover strand 1 6, as shown in Figure 1 . As shown in Figure 1 , the first cover strand 1 6 is wrapped in an S orientation, while the second cover strand 18 is wrapped in a Z orientation. Alternatively, the first cover strand 1 6 can be wrapped in a Z orientation, and the second cover strand 18 can be wrapped in an S orientation.
[0049] As shown in Figures 5 and 6, the glove 10 is generally comprised of a first palm section 50, a second palm section 51 on the opposite side of the first palm section 50, a thumb section 61 , an index finger section 62, a middle finger section 63, a ring finger section 64 and a baby finger section 65, which are formed from the inner primary layer 1 1 .
[0050] A plaiting yarn 21 comprising a strand of four hundred denier UHMWPE is plaited to the primary yarn 1 1 , as shown in Figure 2. The plaiting yarn 21 can be plaited at specific areas on the exterior surface of the inner primary layer 1 1 to form enhanced cut protection sections 20 on areas of the exterior of the glove 10 that are typically exposed to the greatest cutting hazard. As shown in Figures 5 and 6, the enhanced cut protection sections 20 can be formed on the index finger section 62, middle finger section 63, ring finger section 64 and baby finger section 65, except for at the finger tips.

[0071] Alternatively, the glove 10 having touch screen compatible sections 20 can be knit in three layers, utilizing two plaiting yarns 21 , 31 . As shown in Figure 5, an intermediate plaiting yarn 31 comprised of spandex can be plaited to the inner primary yarn 1 1 . The outer plaiting yarn 21 , comprised of an electrically conductive material, is plaited to the intermediate plaiting yarn 31 . The intermediate plaiting yarn 31 can be comprised of a core strand 32 of forty denier spandex, a first covering strand 34 comprised of 20/1 polyester and a second covering strand 36 comprised of forty denier nylon, as shown in Figure 6.
[0072] In an alternative embodiment, the primary yarn 1 1 can be comprised of a first core strand 12 of D225 fiberglass, a second core strand 14 of four hundred denier UHMWPE, a first covering strand 1 6 of one hundred fifty denier textured polyester, and a second covering strand 18 of one hundred fifty denier textured polyester. The plaiting yarn 21 can be comprised of a seventy denier electrically conductive copper-suffused nylon, such as THUNDERON fiber sold by Nihon Sanmo Dyeing Co.
[0073] A protective glove according to another preferred embodiment of the invention is illustrated in Figures 12 and 13, and shown generally at reference numeral 100. The glove 100 is comprised of an inner primary yarn 1 1 1 , and a plurality of spaced apart enhanced sections 120 formed on the exterior surface of the primary yarn 1 1 1 . The enhanced sections 120 are positioned at closely spaced apart intervals 102. In between each enhanced section 120 is an interval 102 that has only the primary yarn 1 1 1 . As such, the enhanced sections 120 have a staggered "hinge" like construction.
[0074] As shown in Figures 12 and 13, the glove 100 is generally comprised of a first palm section 150, a second palm section 151 on the opposite side of the first palm section 150, a thumb section 1 61 , an index finger section 1 62, a middle finger section 1 63, a ring finger section 1 64 and a baby finger section 1 65, which are formed from the inner primary yarn 1 1 1 .
[0075] The inner primary yarn 1 1 1 can have any one of the constructions of the primary yarns 1 1 of the embodiments previously described above. The enhanced sections 120 can be formed by plaiting a plaiting yarn at closely spaced apart areas on the exterior surface of the inner primary layer 1 1 1 using a computer driven jacquard machine. No plaiting yarn is plaited at the intervals 102 in between the enhanced sections 120. The plaiting yarn of the enhanced sections 120 can have any one of the construction of the plaiting yarns 21 of the embodiment previously described above. Alternatively, the enhanced sections 120 can be knit in three layers, utilizing two plaiting yarns, such as is described in reference to the previously described embodiments.
[0076] The enhanced sections 120 can be rectangular, and run substantially perpendicular to the length of the thumb section 1 61 and the index finger section 162, as shown in Figures 12 and 13. The enhanced sections 120 can extend laterally around the circumference of the thumb section 1 61 and the index finger section 1 62, as shown in Figures 12 and 13. In between each enhanced section 120 there is a spaced interval 102 in which there is only the primary yarn 1 1 1 . Alternatively, there can be enhanced sections 120 on any one or more of the other finger sections 1 63, 1 64, 1 65. In yet another alternative embodiment, one or more enhanced sections 120 can extend around the palm sections 150, 151 .
[0077] The enhanced sections 120 can provide enhanced cut resistance, enhanced abrasion resistance and/or enhanced gripping properties, depending on the plaiting yarn used to form the enhanced sections 120. In an embodiment in which the enhanced sections 120 are comprised of a plaiting yarn providing enhanced cut resistance and/or enhanced abrasion resistance, there can be five enhanced sections 120 extending around the circumference of the index finger section 1 62, and four enhanced sections 120 extending around the thumb section 1 61 , as shown in Figures 12 and 13. This protects the wearer at the areas that are typically exposed to the greatest risk of a cutting hazard. Alternatively, the glove 100 can have a different number of enhanced sections 120, and the enhanced sections 120 can be positioned on additional finger sections 1 63, 164, 1 65. [0078] The positioning of the enhanced sections 120 in closely spaced apart alignment with intervals 102 of no plaiting in between the enhanced sections 120 provide a hinge like construction, whereby the glove 100 can provide excellent flexibility, while providing enhanced cut resistance and/or abrasion resistance. This can be particularly important for the thumb section 161 and the index finger 1 62 section.
[0079] In a preferred embodiment, each enhanced section 120 can have a width of about six millimeters, and the spaced intervals 102 between each section 120 can be about three millimeters. The inner primary layer 1 1 1 can have a fabric thickness of about 1 .0414 millimeters, and each enhanced section 120 can have a fabric thickness of about 1 .270 millimeters.
[0080] A protective glove according to another preferred embodiment of the invention is illustrated in Figures 14 and 15, and shown generally at reference numeral 200. The glove 200 is comprised of an inner primary yarn 21 1 , and a plurality of relatively small, spaced apart enhanced sections 220 formed on the exterior surface of the primary yarn 21 1 . The enhanced sections 220 are positioned at closely spaced apart intervals 201 . The spaces 201 between the enhanced sections 220 are comprised of only the primary yarn 21 1 . As such, the enhanced sections 120 have a staggered "speed bump" like construction.
[0081] As shown in Figures 14 and 15, the glove 200 is generally comprised of a first palm section 250, a second palm section 251 on the opposite side of the first palm section 250, a thumb section 261 , an index finger section 262, a middle finger section 263, a ring finger section 264 and a baby finger section 265, which are formed from the inner primary yarn 21 1 .
[0082] The inner primary yarn 21 1 can have any one of the constructions of the primary yarns 1 1 of the embodiments previously described above. The enhanced sections 220 can be formed by plaiting a plaiting yarn at closely spaced apart areas on the exterior surface of the inner primary layer 21 1 . No plaiting yarn is plaited at the intervals 201 in between the enhanced sections 220. The plaiting yarn of the enhanced sections 220 can have any one of the construction of the plaiting yarns 21 of the embodiment 10 previously described above. Alternatively, the enhanced sections 220 can be knit in three layers, utilizing two plaiting yarns, such as is described in reference to the previously described embodiments.
[0083] The enhanced sections 220 can be rectangular, and extend longitudinally on the thumb section 261 and the index finger section 262. The enhanced sections 220 can be aligned to form a plurality of enhanced rings 222 extending laterally around the circumference of the thumb section 261 and the index finger section 262, as shown in Figures 14 and 15. In between each ring 222 there is a spaced interval 202 in which there is only the primary yarn 21 1 and no plaiting yarn. Alternatively, there can be enhanced rings 222 on any one or more of the other finger sections 263, 264, 265. In yet another alternative embodiment, one or more enhanced rings 222 can extend around the palm sections 250, 251 .
[0084] The enhanced sections 220 can provide enhanced cut resistance, enhanced abrasion resistance and/or enhanced gripping properties, depending on the plaiting yarn used to form the enhanced sections 220. In an embodiment in which the enhanced sections 220 are comprised of a plaiting yarn providing enhanced cut resistance and/or enhanced abrasion resistance, there can be five enhanced rings 222 extending around the circumference of the index finger section 262, and four enhanced rings 222 extending around the thumb section 261 , as shown in Figures 14 and 15. This is to protect the wearer at the areas that are typically exposed to the greatest risk of a cutting hazard. Alternatively, the glove 200 can have a different number of enhanced rings 222, and the enhanced rings 222 can be positioned on additional finger sections 263, 264, 265.
[0085] By positioning relatively small enhanced sections 220 in closely spaced apart alignment with spaced intervals 201 , 202 comprised only the primary yarn 21 1 with no enhancing plaiting, the thumb section 261 and the index finger section 262 can have excellent cut resistance and/or abrasion resistance, while also having excellent flexibility. This can be particularly important for the thumb section 261 and the index finger 262 section.
[0086] In a preferred embodiment, each enhanced section 220 can have a length of about six millimeters and a width of about two millimeters. The spaced intervals 101 measured between the lateral sides of each enhanced section 220 can be about one millimeter, and the space 202 between each ring 222 (the distance between longitudinal ends of enhanced sections 220 in adjacent rings 222) can be about three millimeters. The inner primary layer 21 1 can have a fabric thickness of about 1 .0414 millimeters, and each enhanced section 220 can have a fabric thickness of about 1 .270 millimeters. [0087] Protective gloves and methods of making same are described above. Various changes can be made to the invention without departing from its scope. The above description of embodiments and best mode of the invention are provided for the purpose of illustration only and not limitation— the invention being defined by the claims and equivalents thereof.
