Abstract

This invention also relates to stain-masking cut resistant gloves and methods for making the same, the gloves comprising at least one aramid fiber and at least one lubricating fiber selected from the group consisting of aliphatic polyamide fiber, polyolefin fiber, polyethylene fiber, acrylic fiber, and mixtures thereof; wherein up to and including 15 parts by weight of the total amount of fibers in the glove are provided with a dye or pigment such that they have a color different from the remaining fibers; the dye or pigment selected such that the colored fibers have a measured “L” value that is lower than the measured “L” value for the remaining fibers.

Claims (13)

1. A process for making a stain-masking cut resistant glove, comprising:

a) blending

i) at least one pigmented or dyed aramid fiber,

ii) at least one aramid fiber having natural or undyed color, and

iii) at least one fiber selected from the group consisting of aliphatic polyamide fiber, polyolefin fiber, polyethylene fiber, acrylic fiber, and mixtures thereof;

wherein 2 to 15 parts by weight of the total amount of fibers in the blend are provided with a dye or pigment such that they have a color different from the remaining fibers; the dye or pigment selected such that the colored fibers have a measured “L” value that is lower than the measured “L” value for the remaining fibers;

b) forming a spun staple yarn from the blend of fibers; and

c) knitting a glove from the spun staple yarn.

2. The process of claim 1 , wherein the blending is accomplished at least in part by mixing the fibers together and carding the fibers to form a sliver containing an intimate staple fiber blend.

3. The process of claim 1 , wherein the blending is accomplished immediately preceding or during the forming of a spun staple yarn by providing one or more slivers, each of which contains substantially only one of the fiber of i), ii) or iii) to a staple yarn spinning device.

4. The process of claim 1 , wherein the spun staple yarn is formed using ring spinning.

5. The process of claim 1 , wherein the aramid fiber of i) or ii) comprises poly(paraphenylene terephthalamide).

6. The process of claim 1 , wherein 3 to 12 parts by weight of the total amount of fibers in the glove is an aramid fiber provided with a dye or pigment.
