Abstract

PURPOSE: To carry out a treatment by treating a combined fiber structure obtained by combining polyesters different in alkali dissolution rate coefficient under an alkali condition in the same bath in dissolution and dyeing, having an extremely shortened processing process, excellent in general purpose. CONSTITUTION: A polyethylene terephthalate as a slightly alkali-soluble polyester and a polyethylene glycol copolymer block polyether ester as a readily alkali- soluble polyester different in alkali dissolution rate coefficient by >=30 times or more are used, mixed by a static mixer and subjected to bicomponent spinning to give a conjugate fiber having a cross-sectional shape of the two kinds of the polyesters in plural laminated layers in a lamellar state. The conjugate fiber is twisted and used as warp and weft to weave a plain weave. The plain weave is not scoured, fed to a liquid flow dyeing machine, dissolved and dyed under alkalinity of <=pH12 in the same bath at one stage to give the objective dyed material from which the readily alkali soluble polyester is selectively eluted.

These treatments generally go through many steps such as scouring, alkali dissolution treatment, water washing, dyeing and reduction washing. Moreover, since dyeing is carried out with a disperse dye under acidic conditions, in order to prevent color blurring of dyeing, a neutralization treatment is often added after an alkali dissolution treatment, and the complexity is undeniable. Recently, a disperse dye that can be dyed under alkaline conditions has been developed, and a rational dyeing method has been proposed in which a dyeing machine is used to perform alkaline dissolution and then dye under alkaline conditions without neutralization. (For example, new synthetic fiber and alkali dyeing method, Satoshi Kitamura, Processing Technology Vol.27, N

However, even with such a proposal, in order to carry out the alkali dissolution treatment in the jet dyeing machine, the pH of 13 to 14 can be adjusted by using sodium hydroxide or potassium hydroxide.
Since it is set to, it is difficult to dye as it is.
Once the alkaline dissolution treatment liquid was discharged from the jet dyeing machine,
In the present situation, since the dyeing treatment is performed again, the jet dyeing machine also requires a long time to be used. Moreover, there is a problem that it takes a lot of time to treat the wastewater of the alkaline treatment liquid having such a high PH. Therefore, it was a dream of the art to make it possible to carry out the alkali dissolution treatment and the dyeing treatment simultaneously in the same bath.
