Abstract

A cloth suitable for textile printing, mainly composed of silk fibers, is formed of silk threads which have an average thickness of 14 to 147d and which are composed of silk fibers having an average thickness of 2.5 to 3.5d, the cloth having a moisture percentage of 17 to 112%. In an ink-jet textile-printing method, a textile printing ink is imparted to the cloth, and then a dyeing process is conducted, followed by a washing process.

Claims

1. An ink-jet textile printing method comprising the steps of:

providing a cloth comprising silk threads made up mainly of silk fibers, said silk threads and silk fibers respectively having a thickness of 14 to 147 denier and 2.5 to 3.5 denier, and said cloth having a moisture regain of 17 to 112% by weight;

imparting ink to said cloth using an ink-jet printing process; and

conducting a fixing process, and then a washing process on said cloth.

2. An ink-jet textile printing method according to claim 1, wherein said ink-jet printing process utilizes heat energy for imparting an ink to said cloth.

3. An ink-jet textile printing method according to claim 1, wherein said ink contains a dye in an amount of 2 to 25 wt % with respect to the total ink amount, and an aqueous liquid medium.

4. An ink-jet textile printing method according to claim 3, wherein said aqueous liquid medium contains water and a water-soluble organic solvent.

5. An ink jet textile printing method according to claim 1, wherein said cloth contains a water-soluble metallic salt or a water-soluble high molecular weight polymer in an amount of 0.01 to 20 wt % with respect to the weight of said cloth when dry.

6. An ink-jet textile printing method according to claim 5, wherein said water-soluble metallic salt is alkali-metal salt or alkali-earth-metal salt.

7. An ink-jet textile printing method according to claim 6, wherein said alkali-metal salt is a material selected from the group consisting of sodium chloride, sodium sulfate, potassium chloride, and sodium acetate.

8. An ink-jet textile printing method according to claim 6, wherein said alkali-earth-metal salt is a calcium chloride or magnesium chloride.

9. An ink-jet textile printing method according to claim 5, wherein said water-soluble polymer is a material selected from the group consisting of carboxymethyl cellulose, methyl cellulose, hydroxyethyl cellulose, sodium alginate, gum arabic, locust beam gum, tragacanth gum, guar gum, and tamarind seeds.

10. An ink-jet textile printing method according to claim 1, wherein said cloth comprises silk fibers and cellulosic fibers in a blending ratio of at least 70% silk fibers.

11. An ink-jet textile printing method according to claim 1, wherein said cloth has a moisture regain of 18 to 92% by weight.

12. An ink-jet textile printing method according to claim 1, wherein said cloth has a moisture regain of 19 to 72% by weight.

13. An ink-jet textile printing method according to claim 1, wherein said silk fibers have a thickness of 2.7 to 3.3 denier, and said silk threads have a thickness of 14 to 126 denier.

14. An ink-jet textile printing method according to claim 1, wherein said silk fibers have a thickness of 2.7 to 3.3 denier, and said silk threads have a thickness of 14 to 105 denier.

15. An ink-jet textile printing method according to claim 1, wherein said ink is imparted in an amount of 4 to 40 nl/mm².

16. An ink-jet textile printing method according to claim 1, wherein said ink is imparted as ink droplet and the volume of the droplet is in a range of 20 to 200 pl.
