棉/PLA针织物溢流染色工艺实践

Practice of overflow dyeing process for cotton/PLA knitted fabrics

摘要

本文确定了棉及PLA纤维混纺针织物的练漂工艺和亨斯迈高日晒SE系列染料染棉溢流染色条件，染色温度为75-80℃，保温时间为40min，染浅色时Na₂SO₄的用量为5—10g/L，染中色时为11—30g/L，染浅色时固色剂的用量为5—9g/L，染中色时为10—15g/L，确定了SE-黄、SE-红、SE-蓝做三元色；确定了安诺克隆ERD分散染料染PLA溢流染色条件，染色温度为110℃，保温时间为50min，染浅色时分散匀染剂T-150的用量为5—10g/L，染中色时为11—12g/L，确定了分散ERD-黄、ERD-红、ERD-蓝做三元色。

Abstract

This paper established the scouring and bleaching process for cotton/PLA fiber blended knitted fabrics and the overflow dyeing conditions for cotton using Huntsman High Lightfastness SE series dyes. The dyeing temperature was set at 75-80℃ with a holding time of 40 minutes. For light colours, the dosage of Na₂SO₄ ranged from 5-10 g/L, while for medium colours, it ranged from 11-30 g/L. The fixing agent dosage was 5-9 g/L for light colours and 10-15 g/L for medium colours. SE-Yellow, SE-Red, and SE-Blue were identified as the three primary colors for the cotton dyeing system. The overflow dyeing conditions for PLA using Annocron ERD disperse dyes were determined: a dyeing temperature of 110°C with a holding time of 50 minutes. The dosage of disperse leveling agent T-150 was 5-10 g/L for light colours and 11-12 g/L for medium colours. ERD-Yellow, ERD-Red, and ERD-Blue were identified as the three primary colors for the PLA disperse dyeing system.
