the reduction rate and strength loss rate of the tea saponin are gradually increased along with the increase of the dosage of the sodium hydroxide, the sodium lignosulfonate and the tea saponin. Under the general condition of alkali deweighting treatment of polyester fabrics, the using amount of sodium hydroxide is between 5 and 25 g/L; with the increase of the concentration of the sodium hydroxide, the strength damage of the fabric is larger after the concentration of the sodium hydroxide is more than 20 g/L. Comprehensive selection: when the concentration of NaOH reaches 15g/L, the concentration of sodium lignosulphonate reaches 10g/L, and the concentration of tea saponin reaches 25g/L, the fabric feels soft and smooth, and the silk-like effect is optimal.
Example 3:
the preparation method is the same as that of example 1, except that: the influence of the properties such as the K/S value, the fastness to washing, the fastness to rubbing and the like of the fabric is tested by adjusting the using amount of the modified copper/polyacrylate emulsion in the modified paste, and the test is shown in Table 3.
TABLE 3 Effect of the amount of modified copper/polyacrylate emulsion used in the modified pastes on the Properties of the facing Material
Figure BDA0002931125590000072
Figure BDA0002931125590000081
As shown in table 3:
the modified copper/polyacrylate emulsion is added into the modified paste, so that the fabric can obtain good color and luster, and meanwhile, the fabric has excellent color fastness to washing and friction.
Example 4:
the preparation method is the same as that of example 1, except that: the pressing temperature and time were adjusted and the effect of pressing temperature and time on the properties of the facing material was tested as shown in table 4.
TABLE 4 Effect of pressing temperature and time on the Properties of the facing Material
Figure BDA0002931125590000082
As shown in table 4:
the hot pressing temperature is low, the time is short, the K/S value and the outline definition of the fabric are relatively poor, the K/S value and the outline definition of the fabric are obviously improved along with the increase of the hot pressing temperature and the time, however, the hot pressing temperature is too high, the time is long, the hand feeling of the fabric is negatively affected, and energy is wasted. The fabric can obtain good color and luster when the pressing temperature is comprehensively selected to be 210 ℃ and the time is 50s, and the hand feeling and the washing fastness are good.
