Embodiment 1

[0049] The ion-exchange dyeable fine-denier polypropylene fiber with sulfonic acid groups was prepared, and the fiber sample was dyed light red by the following method.

[0050]When dyeing, the fine denier dyeable polypropylene fiber prepared by blending sulfonated polyolefin and polypropylene is added with water at a weight ratio of 1:40, and the dissolved cationic dye red X-GRL 0.1%, leveling agent 1227 Addition amount is 2.0%, Yuanming powder 8%, and acetic acid addition amount is 0.5%. Start temperature control at 25°C, and after running for 20 minutes, raise the temperature to 70°C at 1°C / min and run for 30 minutes. Then the temperature was raised to 100°C at 1°C / min. After running for 30 minutes, drop the residual liquid at 3°C / min to 40°C, wash it twice with 20°C water, and finally dry the dyed fiber or dry it after functional finishing.

Embodiment 2

[0056] Prepare the ion-exchange dyeable fine-denier polypropylene fiber, and then use the following method to dye the fiber sample yellow.

[0057] When dyeing, the fine-denier dyeable polypropylene fiber prepared by blending sulfonated polyolefin and polypropylene is added with water at a bath ratio of 1:40, and the dissolved cationic yellow SD-5GL 1.0% dispersed cationic red SD-GRL0. 3%, Yuanmingfen 8%, and the addition of acetic acid is 1.0%. Start to control the temperature at room temperature. After running for 20 minutes, raise the temperature to 70°C at 1°C / min and run for 30 minutes. Then the temperature was raised to 100°C at 1°C / min. After running for 50 minutes, drop the residual liquid at 3°C / min to 40°C, wash it twice with 20°C water, and finally dry the dyed fiber or dry it after functional finishing.

Embodiment 3

[0063] Prepare the ion-exchange dyeable fine-denier polypropylene fiber, and then use the following method to dye the fiber sample red.

[0064] When dyeing, the fine-denier dyeable polypropylene fiber prepared by blending sulfonated polyolefin and polypropylene is added with water at a bath ratio of 1:40, and then add the dissolved cationic yellow SD-5GL 1.0% dispersed cationic red SD-GRL1. 0%, Yuanmingfen 5%, and the addition of acetic acid is 1.5%. Start to control the temperature at room temperature. After running for 20 minutes, raise the temperature to 70°C at 1°C / min and run for 30 minutes. Then the temperature was raised to 100°C at 1°C / min. After running for 60 minutes, drop the residual liquid at 3°C / min to 40°C, wash with water at 40°C for 3 times, and finally dry the dyed fiber or dry it after functional finishing.

Abstract

The present invention discloses the dyeing method of ion exchange type dyeable fine denier polypropylene fiber. The dyeable fine denier polypropylene fiber contains great amount of sulfo radicals and benzene rings and thus effectively raised dyeability. The method of dyeing the dyeable fine denier polypropylene fiber is to dye with cationic dye, dispersive cationic dye, or the combined dye of dispersive cationic dye and dispersive dye with added acetic acid and at raised temperature. The dyeable fine denier polypropylene fiber may be dyed into medium dark color with excellent color brightness, high homogeneity and high color fastness.

Description

technical field [0001] The invention relates to a dyeing method of ion-exchange fine denier dyeable polypropylene fiber. Background technique [0002] Fine-denier polypropylene fiber is a new type of high-tech functional fiber. Since the single filament fineness is less than 2dtex, it has changed the disadvantages of ordinary polypropylene fiber, such as non-sweat absorption, airtightness, stiff hand feeling, and extremely uncomfortable wearing, and qualitative changes have taken place in physical properties. Leap, has a very good performance. Moreover, the price of fine denier polypropylene fiber is lower than that of natural fiber, so it is very popular among consumers. However, due to the high crystallinity and tight macromolecular structure of fine-denier polypropylene fiber, there is no polar group on the macromolecule that can combine with dye molecules, that is, it has neither dyeing seat nor dye accessible area, so the dyeing performance is extremely poor. , which ...
