Cut and abrasion resistant yarn and protective garment made therefrom

Abstract

Provided is a cut and abrasion resistant yarn and safety garment made from such yarn. The yarn includes a cut-resistant core material, covered by a first wrap having at least one strand of a polymeric material wrapped about the core. A second wrap is included and is wrapped about the first wrap in an opposite direction. The second or outer wrap includes at least one strand having a low coefficient of friction. Also provided is a method of making a protective garment from the inventive yarn wherein the protective garment has increased cut and abrasion resistance.

Description

FIELD OF THE INVENTION [0001] The present invention relates to yarn for machine knitting and to safety garments made with the yarn. BACKGROUND [0002] Gloves and other protective apparel are typically worn by individuals handling and processing food, such as individuals working in the meat packing industry. Preferably, the gloves should be cut-resistant to maximize the useful life of the glove and to provide a degree of protection to the wearer against injury. In addition, the glove should not overly limit the wearer's needed dexterity and tactile sensitivity. [0003] The disclosure of U.S. Pat. No. 4,651,514 issued to Collett provides an example of a cut-resistant yarn. The disclosed cut-resistant yarn has a core of nylon with a first wrap of an aramid fiber and a second wrap of a textured nylon. [0004] An example of a cut-resistant glove is provided by the disclosure of U.S. Pat. No. 5,568,657 issued to Cordova et al. “Comparative Example 10” of the Cordova patent discloses a yarn h...

AI Technical Summary

Benefits of technology

"The present invention provides a knittable composite yarn that is resistant to cuts and abrasions. The yarn has a core that includes a material that causes the outer surface of the yarn to have lower coefficient of friction than other fibers of similar denier and weight. The yarn is flexible and can be used for making protective gloves. The yarn is made by wrapping a strand or fiber of cut-resistant material around a core that includes polyethylene, fiberglass, and stainless steel wire. The yarn has a low coefficient of friction material that can be combined with other materials like polyester or spun Kevlar. The method of making a cut and abrasion resistant garment involves using the knittable composite yarn and knitting it on a knitting machine."

Problems solved by technology

This “scratching” causes instruments to abrade the glove, thus, decreasing the useful life of the glove or garment.
