    Abstract: Spun-dyed aramid fibers, wherein spun-dyeing was performed with a completely organic pigment exhibiting the chemical structure of formula (I): wherein, independently from one another, R1 represents a substituent of formula Xa or a substituent of formula Xb: wherein Xa is linked via the group NH having two bonds in the structure represented by Xa, whilst Xb is linked via the carbon atom, which is in a para relationship with the NH2-group of Xb; and R2 represents H or NH2. The spun-dyed aramid fibers exhibit constant colouristic properties and wash proof properties.

    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 yam. 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 yam spinning. Also disclosed is a method for preparing ramie colored-spun yam.

    Abstract translation: 1)预处理:蒸煮8-12分钟,苎麻纱条在以1:1的浴比的烹调试剂:4-10,该烹饪试剂是1-3克/升wässrige一种用于染色苎麻纱条的工艺,包括 渗透剂的溶液; 和2)染色:染色到活性染料熟苎麻纱条以1:1的浴比:4-10。 游离缺失所以盘是制备苎麻纱的方法。 苎麻棉条染色gemäß到本发明改善苎麻纤维的性能,检查做的苎麻纤维也不易破裂; 和苎麻纤维也不易变硬,避免延伸不良,断针和梳理,并在后程序合并期间失踪针,从而实现顺利纺纱的目的。 所以光盘游离缺失是制备苎麻有色纺纱的方法。

    Abstract: A method for dyeing filaments produced by melt spinning a polyamide composition is disclosed. In particular, the method comprises a step of dyeing the filaments during the filament stretching step. Apart from the stretching step, the method comprises the steps of (i) gathering the filaments produced by spinning a polyamide composition and advantageously collected in the form of a yarn, web, cable or roving, (ii) applying at least one dissolved dye to the collection of filaments, (iii) heating said filaments to at least the glass transition temperature of the polyamide composition, (iv) washing the filaments before or after stretching, and (v) storing the resulting filaments in a suitable form. The resulting filaments are particularly suitable for making short or long fibres or for making bulk continuous filaments or flock cables.
