Abstract
This invention relates to a new assistant which can bath dye wool/ terylene mixture fabric using dispersion dyes, and a new process. With surface excellent activity and solubilization, synthesized aid DEJ can improve rate of dye-up-take, chromaticity value, vividness, color stability of medium clor or light color mixture fabric of wool/ terylene in different degrees, so it offers feasibility and potential applied value of using homogeneous dispersion dyes to substitute blended dyes in bath dyeing of wool/ terylene mixture fabric. Aids DEJ has good steady property, good water-solubility, no objectionable odour,non-environmental contamination, and its molecular formula is C62H128O12N26. No private dispersion dyes are needed in dyeing, except Dispersol SF series, all kinds of dispersion dyes can be used. No carrier is needed in dyeing, and it comprises the following process: 0.1-5%o.w.f DEJ aid, 0.1-8%o.w.f dispersion dyes, pH4-5, bath ratio of 1:50-1:20, starting dye at 40 degrees, dyeing at boiling point for 60min, rinsing, drying. The process is simple, and it favors spread and application.
Description
The present invention relates to a kind of DISPERSE DYES and wool/terylene blending or intertexture are carried out the new auxiliary and the new technology of one-bath dyeing.
Compare with two-bath process, it is simple that the single bath process piece dyeing of wool blended textile fabric has technology, energy-saving and cost-reducing, and the characteristics that environmental pollution is little more can adapt to the requirement of market " high-quality, safety, economy, the fast change ".And the mixed dye one-bath dyeing of present more employing but exists more defective, and therefore the one-bath dyeing that adopts dyestuff of the same race to carry out wool blended textile fabric at present receives much attention.
The present invention adopts single DISPERSE DYES to substitute acidity/dispersion, neutrality/dispersion, media/dispersion or activity/mixed dyes such as dispersion to carry out one-bath dyeing, therefore need to solve three technological difficulties: (1) makes DISPERSE DYES can go up the dyeing wool fiber, and reaches the homochromatism with terylene; (2) increase the enhancing of DISPERSE DYES to polyster fibre, to reduce dyeing temperature, (3) avoid using conventional carrier, reduce the harm that environment and human body are caused.
The technical solution adopted in the present invention is: by synthetic a kind of Multifucntional auxiliary agent with special construction, in dyeing course, can good dispersion and solubilization be arranged to DISPERSE DYES, can stronger swelling and plasticization be arranged to fiber again, and can promote DISPERSE DYES to dying on the dying fiber, to realize that hair/washing the BLENDED FABRIC normal temperature and pressure hangs down pollution dyeing purpose.
The present invention does not relate to every clause of not granting patent of the 25 defined of The Patent Law of the People's Republic of China.Relate to content and put on display in international and domestic exhibition or deliver in any academic conference or technical conference, part Study content is announced in the applicant delivers and send out the scientific paper of table in the recent period.By to uspto web site patent database (http://www.uspto.gov/), the esp@cenet of EUROPEAN PATENT OFFICE network data base (http://esp.espacenet.com/), World Intellectual Property Organization's website patent database (http://www.wipo.int/), Intellectual Property Right Bureau of the RPC (http://www.sipo.gov.cn/), the retrieval of nearly 2 years patent documentations of Chinese patent Information Network (http://www.patent.com.cn/), do not find the patent application of same relevant wool/terylene blend dyeing auxiliary agent the application's day in the past, therefore met primary condition and novelty and the inventive features that Grant Patent Right for Invention should possess.
Auxiliary agent DEJ is synthetic by Mickeal addition reaction and amidatioon condensation reaction.Ethylenediamine and solvent are joined in the there-necked flask that has magnetic stir bar, reflux condensing tube and thermometer, and under 25 ℃ of stirring conditions, the dropwise addition of acrylic acid methyl esters reacted 24 hours, carried out decompression distillation under 20 ℃; Cut and solvent are joined the same device, under 25 ℃ of stirring conditions, drip ethylenediamine, reacted 60 ℃ of following decompression distillation 24 hours; Repeat a said units reaction, obtain product and be called auxiliary agent DEJ.
Through infrared spectrum measurement, auxiliary agent DEJ characteristic absorption peak is 3500-3100cm

2-, auxiliary agent DEJ is repetitive X, Y and primary amine groups (NH
2) and the macromolecular compound that forms by covalent bond of tertiary amine nitrogen atom (N).
The CMC of auxiliary agent DEJ is between 1.6 * 10-3g/L～2.4 * 10-3g/L, and low nearly 2 orders of magnitude of CMC than traditional neopelex have bigger surface-activity thus.DISPERSE DYES had good solubilization.According to DISPERSE DYES under auxiliary agent DEJ effect to the dyeability research of wool and terylene, dye-uptake, color depth value, vividness, the COLOR FASTNESS of proof auxiliary agent DEJ centering look or light wool/terylene BLENDED FABRIC all have raising in various degree, have therefore affirmed that auxiliary agent DEJ carries out the feasibility of wool/terylene BLENDED FABRIC one-bath dyeing and potential practical value in DISPERSE DYES.
The present invention adopts conventional disperse dyeing process, need not special construction or special-purpose DISPERSE DYES, can not be except that Dispersol SF etc. by the DISPERSE DYES of solubilising, and all kinds of commodity DISPERSE DYES all can be selected for use.Auxiliary agent DEJ stable performance, easily water-soluble, free from extraneous odour, environmentally safe.Remove auxiliary agent DEJ, dyeing need not to add in addition carrier, and technology preparation is auxiliary agent DEJ 0.1～5%o.w.f, DISPERSE DYES 0.1-8%o.w.f, pH4-5, bath raio 1: 50～1: 20.40 ℃ are dyed, and boil and dye 60min, flushing, oven dry, so technology is simple, helps applying, and meets the practicality characteristics that Grant Patent Right for Invention should possess.Adopt one of actual effect of this technology dyeing, can be by the dye-uptake data reflection of DISPERSE DYES in the table.
