2.
An activated-carbon fabric according to claim 1, wherein said protective yarn-covered activated-carbon yarn is braided with a cotton yarn.
3.
An activated-carbon fabric according to claim 1, wherein said protective yarn-covered activated-carbon yarn is wrapped with a cotton yarn.
4.
An activated-carbon fabric according to claim 1, wherein said protective yarn-covered activated-carbon yarn is braided with a wool yarn.
5.
An activated-carbon fabric according to claim 1, wherein said activated-carbon fabric has a sorptivity for carbon tetrachloride vapor of at least 1 mg/cm.
sup.
2 of fabric.
6.
An activated-carbon fabric according to claim 1, wherein at least 30 percent by weight of the protective yarn-covered activated-carbon yarn is an activated-carbon yarn.
7.
An activated-carbon fabric according to claim 2, wherein at least 30 percent by weight of said activated-carbon yarn braided with cotton yarn is an activated-carbon yarn and said activated-carbon fabric has a sorptivity for carbon tetrachloride vapor of at least 1 mg/cm.
sup.
2 of fabric.
8.
A protective clothing garment for protection of a wearer thereof against a toxic chemical vapor or gas agent, said protective clothing garment being made of a warp knitted activated-carbon fabric , said fabric having a wept comprising a protective yarn-covered activated-carbon yarn every course thereof being inserted across the full width of said fabric and having non-activated-carbon warp yarns in the wales and courses of said fabric, said fabric being a raschel knit fabric having a design represented by the bar movement pattern: front guide bar: 4-6, 2-0 back guide bar: 2-0, 2-4
