Continuous multicolor screen printing was performed by repeating the following processes using Nos. 1-16 stations of the multicolor rotating screen printing machine (16 stages: The M&R Companies). Prior to the start of printing, only far-infrared dyers were activated to heat each pallet to a temperature of 50-60° C.
After the textile printing process using the multicolor rotating screen printing machine, the printed T shirt was dried by a tunnel dryer at 120° C. for 2 minutes, then heat-treated at 130° C. for 3 minutes.
When 2000 T shirts were printed continuously, the temperature of each pallet was 40-70° C. No clogging of screens with each binder or no thickening of binders occurred during the continuous printing, and no tack developed on the surface of the aqueous tack-prevention textile printing composition after drying by the far-infrared dryer of No. 5 station, no blocking of the printed surface on the back of the next screen occurred; in addition, there was no adhesion of the binder in the 4 colors of aqueous color textile printing compositions on the printed surface to the screens, and no unevenness were present on the printed surfaces.
Thus-obtained T shirts had the white pattern A, red pattern B, yellow pattern C, blue pattern D and black pattern E on the dark blue fabric, with light weight, showing good hiding power and stretch properties.
Furthermore, the T shirts were subjected to 30 times of repeated tests according to the wash fastness test JIS L-0217 103, and showed good wash fastness. Moreover, there was no difference in the quality between the first T shirt and the 2000th T shirt.

Continuous printing of 1000 fabrics was achieved using the rotating screen printing machine without any problems, as in the case of Example 1.
The cut-fabrics obtained had a clearly-printed dog's photo pattern on the red fabric, and their hiding power, stretch properties and wash fastness were superior to those in Example 1 because of the increased number of white ground layers by 1. In addition, there was no difference in the printing quality between the first cut-fabric and 1000th cut-fabric.

The following components were mixed to obtain 100 parts of a homogenous aqueous tack-prevention textile printing composition of white color: 30 parts of an emulsion containing 25% of saturated polyester resin having a Tg point of −26° C. (KZT-0507: UNITIKA LTD.), 10 parts of an emulsion containing 55% of ethylene vinyl acetate resin having a Tg point of 15° C.

The following components were mixed to obtain 100 parts of a homogenous aqueous tack-prevention textile printing composition of white color: 35 parts of an emulsion containing 25% of saturated polyester resin having a Tg point of −26° C. (KZT-0507: UNITIKA LTD.), 7 parts of a dispersion containing 40% of polyethylene resin (CHEMIPEARL W-200: Mitsui Petrochemical Industries, LTD), 17 parts of ethylene glycol, 3 parts of urea, 1 part of 20% sodium hexametaphosphate solution, 20 parts of titanium oxide (Titan R-650: ISHIHARA SANGYO Co., Ltd.), 1 part of a silicone antifoaming agent (Silicone KM-71: Shin-Etsu Chemical Co., Ltd.), 0.3 parts of ammonia water, 2 parts of a thickener (PRIMAL TT615: Rohm & and Chemicals, Incorporated).
As a result, after drying by the far-infrared dryer of No. 5 station, blocking of the textile printing composition printed in No. 4 station on the back of the screen of No. 6 station occurred, leading to lifting up of the T shirt from the stage, thus the textile printing process thereafter became impossible.
Here, strong tack developed on the printed surface after drying by the far-infrared dryer of No. 5 station.
A textile printing process identical to that in Example 1 was performed, except that the amounts of the terpen as an oil and the silicone oil (Silicone SH200: Dow Corning Toray Silicone, Co., Ltd.) in the aqueous color textile printing composition used in Example 1 were reduced to 3 parts and 0.5 parts, respectively, while the total amount of reduction was replaced by water.
As a result, the textile printing composition adhered to the back of the screens in Nos. 7-9 stations, thus stable wet-on-wet continuous printing was impossible, and the textile printing compositions accumulated on the back of the screens as the number of printing increased, resulting in irregular printed surfaces.
A textile printing process identical to that in Example 1 was performed, except that the nonionic surfactant having a cloud point of 40° C. (EMULGEN 108: Kao Corporation) used for emulsifying the oil in the aqueous color textile printing composition of Example 1 was replaced by a nonionic surfactant having a cloud point of 100° C. or higher (EMULGEN 930: Kao Corporation).

As a result, although printing could be performed without any problems immediately after the beginning, as the number of printed fabrics increased, clogging occurred in the screens and each printing composition thickened, and thin printed parts were observed at around 25 fabrics, then fairly significant clogging occurred at around 60 fabrics so that the screen must have been washed to obtain clear printed products.
A textile printing process identical to that in Example 1 was performed, except that the emulsion containing 50% of saturated polyester having a Tg point of −26° C. (KZT-0507: UNITIKA LTD.) in the aqueous tack-prevention textile printing composition used in Example 1 was replaced by an emulsion containing 50% of acrylic resin having a Tg point of −20° C. (VONCOAT AB-781: Dainippon Ink
