酸性染料染木质基材探索

Study on Dyeing of Acid Dyes for Wood Substrate

随着各种类型装饰市场的不断发展和人们对大自然的向往,木材制品市场需求越来越大。木皮产品染色目前市场主要以酸性染料单缸染色为主,单缸染色后大量没被吸附的染料直接以污水形式废弃,造成浪费和污染。纺织印染行业经过数十年发展,纺织品印染加工与木皮染色加工有相类似的处。本项目选择酸性染料,对木材基材选用不同颜色酸性染料、不同上染时间、不同浓度、不同助剂下进行上染率的测试,再在原有残液的基础上续缸,探究染料的利用率对木材单板进行染色研究。

With the continuous development of various types of decoration market and people's yearning for nature,the market demand for wood products is growing.At present,the market of wood dyeing is mainly acid dye single dyeing.This dyeing method leads to waste and pollution.After decades of development,textile printing and dying process is similar to wood dyeing process.In this project,acid dyes are selected to test the dye uptake of wood substrate with different colors,different dye uptake times,different concentrations and different auxiliaries,and makes use of the first dyed residual liquid for the second dye.
