Problems solved by technology

The molecular arrangement structure of PBS is similar to that of polyester fiber molecules, so other hydrophilic dyes cannot be used for dyeing, and the heat resistance and thermal stability of PBS are poor, so the dyeing and finishing method of polyester is not applicable. fiber in PBS

Embodiment 1

[0039] refer to figure 1 , a kind of dyeing process of polybutylene succinate fiber, PBS fiber is carried out following steps processing;

[0040] Step1: Dye liquor preparation; each substance in the dye liquor is calculated by mass percentage: solvent dyestuff is 5%, methanol 30%, N,N-dimethylformamide 55%, and water 10%; Wherein the purity of methanol is 100%, the purity of N,N-dimethylformamide is 100%, and the solvent dye used is C.I. Solvent Black 22. Simultaneously, the preparation of the dye solution comprises the following steps;

[0041] a. First add methanol with a mass fraction of 30% in the container, then slowly add C.I. Solvent Black 22 with a mass fraction of 5% to the container containing methanol, and keep stirring during the addition of C.I. Solvent Black 22 until completely dissolved.

[0042]b. After the C.I. solvent black is completely dissolved in methanol, slowly add 55% N,N-dimethylformamide to the container, and keep stirring during the addition unt...

Abstract

The invention relates to the technical field of dyeing and finishing of polymers and discloses a dyeing technology of poly(butylene succinate) fibers. PBS fibers are treated in the following steps: step one, preparation of a dye solution; the dye solution is prepared from the following substances in percentage by mass: 3 to 7 percent of solvent dye, 25 to 33 percent of methanol, 50 to 58 percent of N,N-dimethylformamide and 2 to 22 percent of water; step two, dyeing; step three, color fixation treatment; step four, dyeing post-treatment, wherein the PBS fibers subjected to the dyeing post-treatment in the fourth step are dyed PBS fibers. Because solubility parameters of the solvent dye are similar to those of PBS, and the methanol and the N,N-dimethylformamide are simultaneously used as solvents, the solvent dye can be dyed on the PBS, and further PBS can be dyed with different colors and the use value of the PBS is improved.

Description

technical field [0001] The invention relates to the technical field of polymer dyeing and finishing, more specifically, it relates to a dyeing process of polybutylene succinate fibers. Background technique [0002] Polybutylene succinate (PBS) is a semi-crystalline thermoplastic and biodegradable aliphatic polyester with good biodegradability, excellent molding performance and good physical and mechanical properties, so It has the most research value and industrial development prospect among biodegradable polymer materials. PBS has a high melting point (about 114°C) and a heat distortion temperature of about 100°C, which is better than general biodegradable materials in heat resistance; compared with other biodegradable materials, PBS has excellent mechanical properties, similar to engineering plastics ABS and general-purpose plastic polypropylene PP; the raw material price of PBS is lower than other biodegradable materials such as polyhydroxyalkanoate, polyhexylpropionamid...
