The dyeing rate was 1.0% (for fabric quality) Fixing time 90min Temperature 105C, bath ratio 1:50; Disperse dyeable dyeable polypropylene filament coloring rate higher than PP / PET fabric coloring Rate: Polypropylene fiber dyeing process Disperse dye color rate Figure 6 from the figure can also be seen in the sample color rate with the liquid concentration of oil "See engaged in scientific research Common polypropylene (pp) filament molecular structure close, no dye molecules to accommodate the space, So the dyeing difficulties, poor performance of the fabric using the modifier on the disperse dyes excellent dyeing, pp and a certain proportion of modifier mixed evenly after melt spinning, can be directly used to disperse dye dyeing polypropylene filament YBP test was used to screen the dyeing conditions of YBP. The optimum dyeing conditions were obtained by comparing the coloration rate of silk samples with different process conditions.

(SBML) disperse blue (ZBLN), Fulong Yanhuang (SE ~ 6GFL), diffusing agent (NNO), phosphoric acid (N), phosphoric acid Ammonium dihydride (or sodium acetate) acetic acid and so on.

R-1180 high temperature and high pressure dyeing machine, photoelectric balance.

1.2 Experimental method Weigh 3g of the sample into the dyeing machine (40C into the dye) temperature, heating rate of Bu 2C / min, pH value of 4.5 to 5.0, rose to a certain temperature, heat for a certain time, and then naturally cooled to room temperature , The sample removed and washed, respectively, the volume of the lotion and the residual liquid, and then through the standard work curve of the dye to obtain the concentration, respectively, the calculation of the color rate 2 results and discussion 2.1 dye concentration on the color rate of different Dye concentration, the coloring rate of YBP samples was increased, but the concentration was increased, the color became darker, the samples were homogeneously colored, and no stains, streaks and so on appeared. At the same time, the coloring rate and the color of the samples Depth, the choice of dye concentration of 0.5% ~ 2 off the appropriate concentration of coloring rate and the relationship between the concentration of dye (time 120min, bath ratio 1:50, temperature 100t: dye for Fu Long Yan.) 22 bath ratio The impact of the color rate of different bath ratio, YBP sample color rate shown in Table 1 can be seen from Table 1, bath than when the sample color rate slightly increased, considering the cost and operation, the general choice of 1:50 Should be fabric and silk uniformity is good, no color.

23 fixing time on the color rate of different fixing time of the sample coloring rate see fixing time is longer, the color rate plus, but more than 90min later, the color rate is not obvious, so the fixing time selection at 90min (Color ratio 1%, bath ratio 1:50, time 120min, the dye is Fulong Yanhuang.) Note: The color ratio of the color ratio is the same as that of the temperature : The dye is Fulong Yanhuang, fixing time is 120min, the concentration is 1% (for the fabric quality), the temperature is 100 �� [, the relationship between the coloring rate and the fixing time (dye concentration 1%, bath ratio 1:50 , The temperature of 100 �� [:], the dye is Fulong Yan yellow.) 2.4 temperature on the color rate of the impact of different temperatures, the sample color rate see from the figure can be seen, the temperature rise, the color rate also increased, but the temperature More than 120C later, silk and fabric feel significantly hard, while taking into account the energy and equipment factors, generally slightly pressurized, select the temperature of about 105C, silk dyeing uniformity are good, no spots, color fastness Good, high color rate.

25 different color ratio of the sample to improve its dyeing, but the PET content of 6% when the color rate is only about 50%, PP / PET fabric YBP-R tow and fabric on the different dye color rate in Table 2 Table 2 several kinds of fabric pressure on the dyeing rate of dye uptake rate, the sample red and blue yellow yellow brown YBP bubble yarn fabric reported dye concentration of 1%. Were higher than PP / PET fabric coloring rate 3 Conclusion YBP filament Dyeing and dyeing, the coloring performance is better than the same conditions, the use of PP / PET blends modified dyeable polypropylene.

The optimum dyeing conditions were as follows: dyeing concentration 1% to fabric quality), fixing time 90min temperature 105C bath ratio 150, under this condition, the fiber coloring rate was 87. 65%, the fabric was soft,
