Epingle (Ep'In-Gle). [French epingle, a slender pin wire] A descriptive term for a variety of thin silk, woven with prominent lustrous raised cords, as if a fine wire had been inserted in place of the weft to make the cords more noticable; though in point of fact hard-twisted worsted threads are used for this purpose in -the better grades, and cotton for the cheaper. The patterns in Epingle silks vary, sometimes there being but a single cord at close and regular intervals, and again two or three together at uneven distances apart. The cords possess a high polish, forming a striking contrast with the lusterless ground. This silk is frequently used for ribbons and cravats.
