Cut, slash and/or abrasion resistant protective fabric and lightweight shaped knit garment made therefrom having improved appearance and cut resistance

a protective fabric and lightweight technology, applied in the direction of protective garments, knitwear, overgarments, etc., can solve the problems of garments that cannot provide a satisfactory level of protection to the wearer of the garment, other known such garments suffer from numerous disadvantages, and can easily be damaged, so as to achieve a satisfactory level of cut

Benefits of technology

The present invention is about a new way to make clothes that are resistant to cutting, scratching, and abrasions. This is done by using a special type of knit fabric that has a high level of resistance. The fabric is made up of a single yarn that is woven into a shaped pattern. The garment is then made by joining together these fabric panels using special yarns that make the seams just as strong as the fabric panels. The invention results in a garment that is light, comfortable, and allows air and water vapor to flow through.

Problems solved by technology

However, these and other known such garments suffer from numerous disadvantages.
The garments are often unable to provide a satisfactory level of protection to a wearer of the garment, are easily damaged, are unwieldy and uncomfortable to the wearer, do not permit airflow therethrough, do not permit the escape of excess water vapor from the skin of the wearer, and often require the use of specialized over- or undergarments.
Previous protective wear in the glass industry suffers from a variety of drawbacks, such as insufficient coverage of the wearer, the presence of metal grommets or other attachment devices which can scratch the surfaces of softer glass, inability to stretch in all directions, and often insufficient cut resistance or weak spots in the areas of seams.
An additional difficulty in preparing cut, slash and abrasion resistant fabrics and garments, is that in order to achieve sufficient cut and slash protection using high-performance fibers, the garments typically end up being too bulky, too heavy, and are difficult to put together, as the fabric cannot be readily cut to necessary size and shape without taking a high toll on the cutting apparatus.

examples

[0056]As an example of a garment prepared according to the present invention, FIG. 1 shows an example of a knit sweater or jacket construction. The sweater can have any desired measurements, depending on the size of the intended wearer. Such sizes and the needed measurements are well known in the art. For example, a knit sweater (1) as shown in FIG. 1 would typically have a rib (10) around the neck opening (11) approximately 1 inch wide, with a front neck drop of 4-4.75 inches and a back neck drop of about 1 inch. The sleeves (12) would typically have a rib (13) at the end approximately 2.5 inches wide. The bottom of the sweater torso would likewise have a rib (14) of approximately 2.5 inches width. The line indicates as (20) represents a zipper, which may optionally be present, depending on whether the garment is a sweater (no zipper) or a jacket (with zipper).

embodiment 1

[0059]A shaped knit garment, comprising:

[0060]one or more fabric panels prepared from at least one cut, slash and / or abrasion resistant composite yarn, wherein the composite yarn comprises a core yarn and one or more wrapped yarn layers, wherein when more than one wrap layer is present, each wrap layer is wrapped in a direction opposite any adjacent wrap layer, wherein the shaped knit garment has a cut resistance of at least 5 (as measured by ASTM-F1790-97).

embodiment 2

[0061]The shaped knit garment of embodiment 1, wherein the fabric weight is no more than 27.9 OPSY.

Abstract

A cut, slash and / or abrasion resistant shaped knit garment having both high cut resistance and preferably light fabric weight, a cut resistance of at least 4, preferably at least 5 (as measured by ASTM-F1790-97) and preferably a fabric weight of no more than 27.9 ounces / square yard (OPSY).

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a lightweight protective fabric that is cut, slash and / or abrasion resistant, and garments made therefrom.2. Discussion of the Background[0002]In many industries and professions there is a need for protective wear that is cut and / or abrasion resistant, yet lightweight and comfortable for the wearer. From maintenance workers crawling through HVAC ventilation shafts to weekend warriors participating in various sporting events, many individuals need protection from cuts and scrapes as they go about their daily activities.[0003]Typical examples of previous garments and modular systems are disclosed in U.S. Publication No. 2004 / 0199983 to Gillen; U.S. Pat. No. 6,892,392 to Crye; U.S. Pat. No. 6,698,024 to Graves; U.S. Pat. No. 6,263,509 to Bowen; U.S. Pat. No. 6,185,745 to Alger; U.S. Pat. No. 6,182,288 to Kibbee; U.S. Pat.
