Abstract
The present invention is a kind of cation modifying method of cellulose fibre, and the method adopts liquefied ammonia to be reaction medium, reduces modification time, solves the problem using and produce contaminated wastewater of cation modifying process base agent.
Description
Technical field
The present invention relates to a kind of cation modifying method of cellulose fibre.
Background technology
All the time, cellulosic cation modifying mainly solves one of effective ways that dyestuff dye-uptake is low, COLOR FASTNESS is poor.Its principle mainly by chemical bond or physical absorption by cationic compound process on fiber, improve the affinity between dyestuff and fiber, improve the dye-uptake of dyestuff on cotton fiber.But existing cation-modified method is carried out in aqueous, and in modifying process, add base agent carry out fixation reaction, therefore produce pollutant effluents.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of cation modifying method of cellulose fibre, and the method adopts liquefied ammonia to be reaction medium, reduces modification time, solves the problem using and produce contaminated wastewater of cation modifying process base agent.
A kind of cation modifying method of cellulose fibre: it is characterized in that the method comprises the following steps:
Step one: the configuration of reagent, is dissolved in cation modifier in liquefied ammonia, and described cation modifier consumption 1%-50% (o.m.f), described liquefied ammonia consumption is 100mL.
Step 2: 4g cellulose fibre is immersed in the liquefied ammonia containing cation modifier and carries out modification and dry set, obtain cationized cellulose fiber;
20 seconds-20 minutes immersion processing time in described step 2, bake out temperature 95-180 degree Celsius, drying time 1 minute-10 minutes.
It is characterized in that, described cation modifier is 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, and cellulose fibre is cotton.
It is characterized in that, the immersion processing time in described step 2 is 5 minutes, bake out temperature 180 degrees Celsius, and drying time is 3 minutes.
Principle of the present invention is: under cellulose fibre is swelling rapidly in liquefied ammonia, cation modifier enters in cellulose fibre rapidly, then the reactive group in cation modifier and the hydroxyl reaction in cellulose fibre under drying condition, complete cation modifying.
The present invention compared with prior art, has following main advantage:
One. solve the problem of length of existing cellulose fiber cation modifying process time.
They are two years old. solve the problem using base agent in existing cellulose fiber cation modifying process.
They are three years old. and solve the problem that existing cellulose fiber cation modifying process produces water pollutions, realize the anhydrous requirement of cation modifying.
