The test of dye adsorption rate
The test of dye adsorption rate is carried out to the fiber sample of preparation, the dyestuff being adopted is Reactive Brilliant Blue KN-R (cas:
2580-78-1), comprise the following steps that：
1) weigh 0.600g fiber sample (being accurate to 0.005g) with analytical balance, then its continuous doubling cut off 4 times,
Until be cut into the length of side be 1cm about square fragment.
2) take 50mL volumetric flask, weigh 0.500g reactive brilliant blue K-GR, deionized water dissolves constant volume, obtain 1.0% and live
Property gorgeous blue standard dye solution；
3) according to GB/T 13174, prepare the hard water solution (250ppm) of 1.0L standard containing 2.0g/L liquid detergent.
4) take 500mL beaker, add 3.00g above-mentioned standard dye solution and 497g hard water solution, obtain 60mg/L dyestuff
Solution；Separately take two same specification 250mL beakers, weigh 200mL dye solution (60mg/L), add magneton, be placed into agitator
Central authorities.
5) (rotating speed is 250rpm at ambient temperature, to open magneton stirring；If no magnetic stirring apparatuss, machinery can be changed to and stir
Mix)；After 1min, it is separately added into fiber sample in two beakers, and starts timing；Stop stirring, standing is about after Preset Time
About 30mL upper solution is gently taken with plastic bottle after 5s, must not fibre-bearing sample.
Note：If there is magneton irregular movement during stirring, incrementally increase again to 250rpm after rotating speed is returned to zero.
6) use ultraviolet light absorption angle value A at uv analyzer sample solution 592nm, calculate fiber by following formula
The dye adsorption rate of sample, and obtain with the dyestuff average adsorption rate organizing two beaker fiber samples.
Adsorption rate
The design factor of 0.0084,0.01273 Reactive Brilliant Blue KN-R concentration absorbance standard curve；
The initial concentration value of 60 dye solutions.
Fig. 1 show dye solution respectively through embodiment 1-4 and comparative example 1 preparation fiber sample absorption 3min after
It can be seen that the color of embodiment 2-4 is the most shallow, most of dyestuff is adsorbed photo by fiber sample, and embodiment 1 color is slightly deep, inhales
Attached effect is slightly poorer than embodiment 2-4, and comparative example 1 color depth is significantly higher, and most of dyestuff is not all adsorbed.As shown in table 3,
The anti-colour contamination fiber of embodiment 1-4 preparation has outstanding dye adsorption ability compared with comparative example 1, with inorganic base and 3- halogen
The concentration of generation -2- hydroxypropyl trimethylammonium based quaternary ammonium salt increase and the response time growth, the purpose product of generation also increases, to containing
The chemical modification of the fiber of hydroxyl is also more thorough, and dye adsorption performance gets a promotion, and embodiment 3 and embodiment 4 are only in 3min
Just adsorbable 70% about dyestuff.And embodiment 1-4 and comparative example 2 phase using polycyclic oxygen trimonium chloride
Ratio all shows considerably higher adsorption rate (even if comparative example 2 is up to the adsorption rate of 10min also only 20.1%), using 3- halogen
Generation -2- hydroxypropyl trimethylammonium based quaternary ammonium salt can significantly improve the suction color effect of fiber sample.Polycyclic oxygen trimonium chloride
Molecular weight larger, be mainly distributed on fiber surface it is impossible to fibrous inside infiltration, so internal fiber absorption cannot be made free
Dyestuff, and the color fastness between fiber and dyestuff is relatively low.
The dye adsorption rate of the fiber sample of table 3 embodiment 1-4 and the preparation of comparative example 1-2
The dye adsorption rate test result that table 4 show embodiment 5-8 controls 3- halo -2- hydroxypropyl it can be seen that working as
The mol ratio of trimethyl quaternary ammonium salt and inorganic base is in 1.67-2.5:When in the range of 1, the adsorption rate of anti-colour contamination fiber sample has bright
Aobvious raising, can be effectively reduced the generation of side reaction, be greatly enhanced the suction color performance of anti-colour contamination fiber.
The dye adsorption rate of the fiber sample of table 4 embodiment 5-8 preparation
Embodiment 5
Anti- colour contamination fiber is added with the oil preparation of its weight 1.0%, then with spun lacing method by anti-colour contamination fiber and ES fiber system
Become anti-colour contamination cloth, the mass ratio of wherein anti-colour contamination fiber and ES fiber is 4:1, then anti-colour contamination cloth coiled material is cut into piece, and
Carry out Amscomatic.
