ABSTRACT:
The present invention relates generally to fabric decoration using ink jet spraying apparatus and processes and, more particularly, to accommodating the operating mode of the apparatus to the characteristics of the fabric to contribute to achieving more effective decoration of the fabric.
EXAMPLES OF THE PRIOR ART
Decorating fabric preparatory to manufacture into garments, and other end uses is achieved by dying, roller printing and, currently by the technique, now of choice which uses ink jet spraying apparatus described and illustrated in many prior patents, two such exemplary patents being U.S. Pat. No. 5,687,197 for “Ink-Jet Printing Cloth, Ink-Jet Printing Process And Production Process Of Print” issued to Aoki on Feb. 2, 1999 and U.S. Pat. No. 5,847,739 for “Cloth Feeding Drum For Ink-Jet Printing” issued to Kanaya et al. on Dec. 8, 1998. The noteworthy decorative results apparently warrant the use of jet spraying despite its intricacies, as perhaps best expressed in the '739 patent at col. 1, in lines 49-52 that “In order to accurately form line and delicate patterns with ink jet printing, the distance between the ink jet nozzle and the cloth surface must be kept constant while the nozzle head is moving along the width of the cloth, and the cloth printing surface must be substantially flat.”
If an unsatisfactory decorative pattern is produced, the effort, even by those well versed in the art, is to seek correction in the parameters above noted, namely in adjustments in the distance between the ink jet nozzle and the cloth surface, or in the tracking of the nozzle head and so on. Even with such adjustments however, inexplicable unsatisfactory decorative results still persist, and the solution remains elusive.
Broadly, it is an object of the present invention to minimize unsatisfactory decorative results by not limiting corrective techniques to operating parameters of the apparatus, as is now done and is a major shortcoming of the prior art.
More particularly, it is an object of the present invention to achieve a synergism of the jet spraying apparatus and of the fabric being decorated which minimizes the heretofore inexplicable unsatisfactory decorative results, all as will be better understood as the description proceeds.
The description of the invention which follows, together with the accompany ing drawings should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof within the ambit of the appended claims.
