Description
Technical field
The present invention relates to the strength of fluid field of measurement, specifically the dye liquor concentration on-line measurement system.
Background technology
Textile product is seen everywhere in our life, and the color of these textiles and pattern generally are to process through the mode of printing and dyeing.In the textile printing and dyeing process, the concentration of dyestuff is all changing at any time in the dye liquor.Consistent in order to guarantee the product colour of textile in dyeing course with standard specimen, need monitor at any time dyestuff in the dye liquor component and change in concentration, on dye temperature, dye-uptake etc.The colouring method of yarn fabric can be divided into to be contaminated and two kinds of pad dyeing.All the time, in dyeing process, the technician who is responsible for dyeing mainly relies on the experience of its long-term accumulation, and dye component in the dye liquor and concentration are adjusted, and obtains to satisfy the aberration rank of order requirements.Staining method as with pad dyeing dyes to textile; In the mangle groove concentration of dye liquor with the carrying out of tinction in continuous variation; For guaranteeing the self-consistentency property of dyed fabric colouring; The real-time concentration of each component dyestuff in the mangle groove be must understand, and then additional dye liquor, dye component and the magnitude of recruitment of dye liquor in the mangle groove fully by virtue of experience judged this moment.And for contaminating mode to textile dyeing, dyestuff in different time and temperature range on dye behavior (being dyeing speed) to formulate the dyeing heating curve, select dyestuff with auxiliary agent, control dyeing quality, enhance productivity etc. most important.But, owing to lack the on-line monitoring equipment of effective dye strength in the prior art, and can only be based on the result of laboratory simulation production and the experience of accumulation, limit production limit adjustment when production equipment moves.In this case, because the too much artificial experience of dependence of dyeing process just is difficult to homogeneity, consistance and printing and dyeing efficient that assurance is dyeed.
Because the variation of real-time and dynamic monitoring dye concentration can real-time information be provided for the dyer author, thereby create conditions for adjusting dye liquor concentration accurately and timely, so real-time and dynamic monitoring dye concentration is most important.In addition; In the production field of textile; To in the performance evaluation of the dyeability analysis of fiber, dyestuff, the dyeing course between the dyestuff and the transactional analysis between dyestuff and the auxiliary agent etc.; All be that change in concentration with the test dye liquor is a foundation, carry out the profound level analysis of different directions again, so the change in concentration of dyeing process be that the analysis of above-mentioned numerous projects provides condition.
