Acidic dyeable polyester and method for preparing acidic dyeable polyester and fiber thereof

ActiveCN101450990AUniform dyeingAffinityMonocomponent copolyesters artificial filamentDyeing processFiberFormate

The invention relates to acidic dyeable polyester and a method for preparing acidic dyeable polyester chip and fiber. The method comprises the steps of performing transesterification or esterification to p-phenyl dimethyl formate or p-phenyl dicarboxylic acid and glycol, adding polyamide such as nylon 6 and / or nylon 66 during polyester polymerization so as to prepare polyester chip, drying the polyester chip and using a conventional spinning machine to spin so as to prepare the polyester fiber used for the dyeing of acid dye. The polyester fiber thoroughly solves the problem that polyester and polyamide are not compatible, ensures uniform dyeing of acid dye, and enables spinning workstage to proceed smoothly. In addition, as the preparation of the polymer adopts a process similar to polyester polymerization for polymerization on a common polyester polymerization device, the method is simple to operate, easy to perform industrial production and low in cost.

In order to meet the needs of customers in the product market and solve the problem of poor spinnability of the bamboo charcoal viscose fiber, the invention provides a trilobal bamboo charcoal viscose fiber and a production process thereof. It is characterized in that: the bamboo charcoal pulp is mixed with viscose by pre-spinning injection, and obtained by wet spinning and post-treatment; the cross section of the fiber is trilobal, and the aspect ratio of the cross section is 10~200:1; the bamboo charcoal The content is 0.1~10% of the total weight of the fiber, the ammonia absorption rate is ≥60%, the air permeability is ≥500mm / s, and the color fastness to washing is 4~5. The trilobal bamboo charcoal viscose fiber of the present invention has a large surface area of the fiber cortex, and under the premise of maintaining the sterilization, deodorization, far infrared, and odor absorption effects of the bamboo charcoal viscose fiber, the hygroscopicity is better, and the additional value of the product can be greatly improved. , more comfortable to wear, and maximize the excellent characteristics of bamboo charcoal fiber.
