ABSTRACT:
A knitting yarn for gland packing according to the present invention has a composite structure comprising: a string-like body formed by folding an expanded graphite tape in the widthwise direction thereof thus forming folded layers; a first reinforcing member made of a knitted or braided body for covering the entire outer peripheral surface of the string-like body; and/or a yarn-like second reinforcing member interposed between the folded layers of the string-like body in the longitudinal direction thereof. A plurality of such knitting yarns are braided or twisted to form a gland packing. According to the present invention, the formation of an expanded graphite tape is facilitated and no slip is presented between the folded layers, thus providing a knitting yarn for gland packing excellent in strength and shape retention. With the use of such knitting yarns, brading or twisting can be facilitated and the resulting gland packing can be considerably improved in sealing performance.
