The proportioning for being a difference in that each raw material of comparative example 4-6 is different, and ibid, the pH for measuring is different, is shown in Table lattice for method.
The techniques such as the spray printing identical with the slurry experiment use of comparative example 1-6 of embodiment 1, washing, the difference is that only slurry
Material formula and proportioning.
Embodiment 1 is as follows with the slurry contrast test test result of comparative example 1-6：
Tested by slurry and found：Cashmere is poor to the resistivity of weak base, when slurry pH value is more than 9, the damage of fiber
Wound is serious.When the pH value of slurry is in 5 (near isoelectric point), cashmere fiber is not interfered with strongly.But the alginic acid in slurry
Sodium is very insoluble transparent and uniform in micro- sour condition, the color development of road ink after influence, so slurry pH range should be neutral,
Optimize technique pH value is controlled between 5.5-6.5.
On the basis of sodium alginate thickener and the mixing of DGT-7 thickeners, analysis urea accounting is to fleece fabrics spray printing effect
The influence of (tinctorial yield, fineness).Result is shown in that (Fig. 1) data can be seen that with the increase of urea accounting, tinctorial yield (K/S
Value) be significantly improved, to urea accounting be more than 8% when, the increasing degree of tinctorial yield is gradually reduced.
With the increase of urea accounting, tinctorial yield is improved simultaneously by a small margin, and spray printing fineness can gradually be deteriorated, when urea reaches
During to 10%, textile printing flower pattern lines do clear on fabric, but obvious imbibition, vision epigraph occur again after exceeding
Definition occurs significantly to deteriorate, and black is most obvious.As can be seen here：The factor of comprehensive tinctorial yield and fineness these two aspects, urea
Proportioning determine between 8%-10% be optimum process.The very few osmotic effect of urea is bad, so final choice is of the invention
Scheme is optimal formula of size.Using this project technique, fiber strength is damaged and quality index reaches more satisfactory level, especially
Its strength damage is smaller.
