超细锦纶PU合成革中性染料染色性能的研究
2.
Kinetics of ultrasonic dyeing of wool with neutral dyes;
基于超声波的中性染料羊毛染色动力学研究
3.
Dyeing behaviors of neutral dyestuffs on supermicro PA/PU synthetic leather are discussed.
采用中性染料(尤丽特染料)对超细锦纶PU合成革染色,通过正交试验优化染色工艺条件:染浴pH值4,染色温度90℃,染料浓度4%~6%,浸染时间80 min,匀染剂用量1。
6) neutral dye
中性染料
1.
On the basis of analysing the cause of dye spots and dyeing property of neutral dyes, it is found that the fabric weak-acid initial dyeing can be carried out at a high temperature,resulting in better quality products with even dyeing effects due to higher stable shades.
中性染料以中性或弱酸性低温起染工艺染色真丝绸时,由于染料沉淀或凝聚,容易引起色点病疵,文中在分析色点成因及中性染料染色性能的基础上,采用微碱性高温起染工艺,解决了色点病疵,成品匀染效果良好,并对稳定色光、控制色差有利,提高了产品质量。
2.
Some of deep color metal complex acid dyes including neutral dyes had the merits of dark shades,high dyeing fastness,light fastness,weather fastness and wet fastness,but they were limited or inhabited by environmental rules because the heavy metals they are containing could do serious damage to the human health and environment.
酸性染料是一类重要的染料,广泛用于羊毛、丝绸、锦纶和皮革的染色,其中一些深色酸性金属络合染料包括中性染料,具有深浓色调、着色强度高、耐光、耐气候和湿牢度好的优点,但因含有有害重金属,对人体健康和环境造成严重危害,受到环保法规的限用或禁用。
补充资料:丹宁媒染剂
分子式:
CAS号:
性质:某些阳离子染料(俗称碱性染料)在对棉织物染色时所用的药剂。常用的是丹宁,又称鞣酸,为双樯酸葡萄糖甙化合物,分子大而复杂,主要用作鞣革剂。因加入这类媒染剂后的染料在棉织物上的染色牢度差,已被淘汰,它也失去了媒染剂的意义,但可作某些酸性染料染锦纶(聚酰胺)的后固色剂。
