如何对还原染料染色织物进行剥色?

从理论上来说,还原染料染色织物实现完全剥色是有可的,但在实际生产中,对还原染料的染色织物进行剥色的确是很困难的,由于还原染料结构上的差异,同一种剥色剂在不同还原染料的染色织物剥色过程中其剥色效果差异很大。

热固型活性染料,含有不同于其他类型活性染料的活性基团,它以季铵型吡啶甲酸为离去基,与纤维素纤维的固着反应如下:

热固型活性染料,虽属于活性染料范畴,但由于它带有别样的活性基团,所以对染色条件的要求,与其他类型活性染料既有相同之处,又有重大差异。

(1)染色温度的设定。热固型活性染料所带的活性基团,化学活性相对较强,在≥100℃的条件下(严格来讲是在70℃以上),其B-吡啶甲酸便会产生消去反应,染料就能与纤维素纤维发生共价键结合而固着。这类染料可以采用高温(≥100℃)固色,而完全摒弃固色碱剂。

What are the advantages and disadvantages of woven fabrics? Woven fabrics are made by weaving yarns together on a loom using a shuttle, with the yarns interlacing in the warp and weft directions. Structurally, these fabrics have a clear distinction between warp and weft. Common weave types include plain weave, twill weave, and satin weave, as well as variations thereof. Woven fabrics come in a wide variety, and based on their composition, they can be categorized into cotton fabrics, silk fabrics, wool fabrics, linen fabrics, synthetic fiber fabrics, and blended and interwoven fabrics. They are widely used in garment manufacturing, holding a leading position in both variety and production volume.

Classification and Causes of Neps in Yarn Neps are a crucial indicator of yarn quality. Technical requirements for cotton yarn grades specify not only the total number of neps and impurities per gram of yarn, but also the specific number of neps. The amount of neps affects not only the appearance quality of the yarn and fabric, but also the yarn structure, evenness, and yarn breakage rate.
