Method of making a bulky multifilament heather yarn, yarn so obtained and carpet containing such a yarn in its pile. |
摘要 |
<p>An improved method for making a continuous filament heather dyeable yarn involves cobulking in a hot fluid jet process a first unbulked yarn with a second differentially dyeable previously bulked yarn. The method enhances differential dyeability in the product when both yarns have a common type of chemical dye site and the second yarn has a greater concentration of those dye sites than the first yarn.</p> |
