Abstract: A process for dyeing ramie sliver, comprising: 1.) pretreatment: cooking the ramie sliver for 8-12 minutes in a cooking reagent in a bath ratio of 1:4-10, the cooking reagent is a 1-3 g/L aqueous solution of a penetrating agent; and 2.) dyeing: dyeing the cooked ramie sliver in an active dye in a bath ratio of 1:4-10. Also disclosed is a method for preparing ramie yarn. The ramie sliver dyed according to the present invention improves the properties of ramie fibers, such that the ramie fibers are less likely to break; and the ramie fibers are less likely to harden, avoiding poor drawing, needle breakage and missing stitches during carding and coalescing in post-procedures, thus achieving the purpose of smooth yarn spinning. Also disclosed is a method for preparing ramie colored-spun yarn.

Abstract: The present invention relates to a process for manufacturing a ramie fabric and the fabric. The process comprising the following steps: blend spinning a high-count ramie fiber such as a ramie fiber of 2500Nm or higher with a water-soluble fiber as carrier to form a yarn; sizing the yarn at a low temperature; weaving the yarn to form a gray fabric; then removing the water-soluble fiber from the gray fabric by deweighting the gray fabric during a printing and dyeing finishing process to obtain a super-high-count ramie fabric with a ramie yarn fineness of 160Nm or higher.
