Abstract
The invention discloses a kind of method for dyeing terylene using nano lanthanum oxide, nano lanthanum oxide particle is surface modified first, alkali process is carried out to terylene again, using silane coupling agent by after surface modification nano lanthanum oxide and alkali process after terylene carry out coupling reaction, finally, to coupling, treated that terylene dyes using support methods；The affinity between carrier and disperse dyes, carrier and polyester fiber can be improved through stearic acid esterification in lanthana after surface modification, so as to reduce the glass transition temperature of terylene, therefore, after lanthana after stearic acid surface-modified is coupled to terylene surface, improve the diffusion rate of carrier and disperse dyes, so that carrier and disperse dyes is entered polyester fiber with either as singular molecular entities, improves the dye-uptake of dyeing rate and scattered dyestuff；And reaction temperature is relatively low, be conducive to carry out terylene it is blended after dyeing.
Description
Technical field
The invention belongs to fabric dyeing method technical fields, are related to a kind of method for dyeing terylene using nano lanthanum oxide.
Background technique
The basic structural unit of polyester fiber is polyethylene terephthalate, terylene molecular weight generally 20000 or so,
Impurity containing 1%-3%, chemical structural formula are as follows:
It is the basic chain link of terylene macromolecular in square brackets in formula, n is average degree of polymerization, about 130.Polyester fiber it is big
There are two kinds of conformational forms of folded chain and extended chain for strand, from the point of view of polyester fiber molecular composition, it be by short fat hydrocarbon chain,
Ester group, phenyl ring and terminal hydroxy group are constituted.Therefore, polyester fiber is except having no other polar groups there are in addition to two terminal hydroxy groups, thus washs
Synthetic fibre fiber category hydrophobic fibre.The skin-friction coefficient of polyester fiber is very big, about 0.26-0.58, and electrical insulating property is high, and rub pole
It is easy to produce static electricity, to influence going on smoothly for textile process, cause float, specking.
The continuous personalized, abundantization of requirement and effect due to people to garment fabric, it emerges largely not
With the fabric of fiber, such as silk, spandex, wool, vinegar fibre, but these fibers are easy denaturation at high temperature.Terylene possesses parent
The aqueous low, characteristics such as crystallinity is high, fiber alignment is close and is not easy to soak, generally use water-soluble lesser non-ionic dispersant
Dyestuff dyes it by dispersing agent NNO.Since the glass transition temperature of polyester fiber is higher, disperse dyes is made to exist
Entered inside terylene under Room-temperature low-pressure with high dispersive degree and achieve the effect that thoroughly upper dye is difficult to complete, thus how
Carrying out dyeing to polyester fiber under atmospheric low-temperature is the hot spot studied now.Wherein, since terylene hydrophily is poor, it is unfavorable for dyeing
Characteristic, the surface that more sight are invested terylene by current people is modified.The surface modification of terylene, which refers to, does not change terylene fibre
Premised on tieing up script material and its performance, PET fiber surface is made to obtain new characteristic, as hydrophily, dyeability, resistance to ag(e)ing,
Biocompatibility, antistatic property etc. make the characteristic of terylene maximize favourable factors and minimize unfavourable ones, are more widely used.
With the development of textile printing and dyeing science and technology, it should be noted that nano material is depended primarily on as dyeing assistant
Its skin effect.The skin effect of nano material depends primarily on the size of its partial size, and as partial size reduces, specific surface area is significantly
Increase, skin effect greatly improves, and therefore, how to obtain compared with the nanoparticle of small particle to its assisting-dyeing performance of raising with important
Meaning.
Summary of the invention
The object of the present invention is to provide a kind of method for dyeing terylene using nano lanthanum oxide, improve terylene dye-uptake.
The technical scheme adopted by the invention is that a kind of method for dyeing terylene using nano lanthanum oxide, specifically according to
Lower step is implemented:
Step 1: nano lanthanum oxide particle being surface modified using dehydrated alcohol and stearic acid；
Step 2: alkali process is carried out to terylene using sodium hydroxide solution；
Step 3: using silane coupling agent kh560 by after surface modification nano lanthanum oxide and alkali process after terylene carry out
Coupling reaction；
Step 4: configuration dyestuff, acetic acid, dispersing agent NNO and gaultherolin mixed solution, using support methods to coupling at
Terylene after reason is dyed, wherein dyestuff, acetic acid, dispersing agent NNO and gaultherolin dosage be respectively terylene quality
1.0%~3.0%, 1.0%~3.0%, 1.0%~3.0% and 1.0%~3.0%, reaction temperature is 85 DEG C~95 DEG C, instead
It is 30min~50min between seasonable.
The features of the present invention also characterized in that
Step 1 is specifically implemented according to the following steps:
Step 1.1: nano lanthanum oxide powder is weighed, by it in 80 DEG C~90 DEG C dry 3h~4h；Measure dehydrated alcohol with
Stearic acid mixing, the nano lanthanum oxide powder after drying is added thereto, at room temperature supersonic oscillations, is stirred, and mixing time is
25min~35min obtains mixture A；
Step 1.2: the mixture A that step 1.1 is obtained carries out oil bath reflux, and oil bath temperature is 75 DEG C~85 DEG C, oil bath
Time is 5.5h~6.5h；
Step 1.3: the mixture A after step 1.2 oil bath is filtered, is rinsed using dehydrated alcohol, it will
Products therefrom is put into vacuum oven and is dried, and drying temperature is 75 DEG C~85 DEG C, and drying time is 23h~25h, obtains
Surface finish nano lanthana.
Nano lanthanum oxide mass fraction is 0.9%~1.1% in step 1, and dehydrated alcohol dosage is 91.9%~94.1%,
