*2: through storing the distance that liquid reduces in the postcapillary, * representative is separated out fully.
Learn from the result of table 1, use the weight loss of additive (II-1) compound little among the embodiment, obviously be better than adding sample and the blank comparative sample of urea.The degree of volatilizing in experiment capillaceous in addition uses the degree of the less representative volatilization of the decline of additive (II-1) compound lower among the embodiment, then represent ink and be not easy to form a scab at nozzle surface without separating out.
The result of experiment shows, uses (II-1) compound that the character (being not easy to make ink to separate out) of good reduction weight loss effect and inhibition crystallization can be arranged.
Use hexanolactam (caprolactam) that good reduction weight loss effect can be arranged, but in the kapillary test, separate out easily.
Use the reduction weight loss effect of urea (urea) relatively poor, but be difficult for separating out.

*2: paint dynamics as 100%, wherein with the ink after printing property testing---it is not good for take off data to represent ink printed.
Can be known by table 2 result, any digital textile ink composition in the embodiment of the invention, its " printing " reach " through the time print property " all present good test result, and the digital textile ink composition in the embodiment of the invention also has good high temperatrue stability.
Utilize digital textile ink composition that dye component of the present invention makes " through the time print property " reach " and through the time dye uptake " on the result of excellence is arranged, wherein through the time dynamics fading rate of painting can be controlled in 5%.In addition, the printable cloth material of chemically-reactive dyes ink of the present invention has cellulosic fibre and regenerated fibre thereof, comprises cotton, artificial silk and as the natural fibers such as silk or wool.
In sum, no matter the present invention is with regard to purpose, gimmick and effect, or with regard in its technological layer and the research and development design, shows that all it is totally different in the feature of known technology.It should be noted that so above-mentioned many embodiment set forth for example for convenience of explanation, and the interest field that the present invention advocates is from should be with described being as the criterion of claim scope of application, but not only limits to above-described embodiment.
