Printing paste is printed as a coloring agent Paint The important part of the apparent decision of the printing performance, part of the fastness properties and Environmental protection Performance. With the development of science and technology, more and paste the pursuit of high concentration, high fastness and high environment-friendly and cost-effective. Recommend high-quality paste shops: Banfu Town, Zhongshan City, China Printing Materials Factory Wing So in accordance with the printing paste used in textile printing pigment types can be divided into the following three: 1. Organic pigment paste: red, yellow, blue, green and purple mainly paste, and can match each other in order to bring up a richer colors, such colorant fastness and there is, there are good environmental protection bad, in general, fastness and environmentally expensive, poor fastness of the environment, cheaper, so the price varies greatly. 2. Inorganic pigment paste: mainly black and other colorants, such colorants shade more gloomy, but the color fastness is very high and environmentally friendly and inexpensive. 3. Fluorescent pigment paste: This type of paste and bright shade, but color strength is low, and poor fastness, in particular resistance to transfer (sublimation), currently on the market that is environmentally friendly and virtually no resistance to migration of species, So to some extent limit the use of such colorants; the recent market move also appeared resistant fluorescent colorant, but it can not fully meet the child standard formaldehyde; the middle price of these products. II fastness properties of printing paste 1. Light fastness: light fastness of printing paste is mainly determined by the general 5% paste printing through a carbon arc lamp, after 20 hours determined according to (8 preferably a worst ) in general paste, the blue-green light fastness is better red, yellow, orange and the poor. 2. Heat fastness: heat fastness of printing color paste is mainly determined by the general adoption of 1% of the paste after printing temperature 180-200 Pressing Measured 30 seconds, 5 the best one the worst. In general color paste, the blue-green heat-fastness is better, red, yellow, orange and the poor. 3. Resistance Solvent Fastness: The solvent fastness of printing color paste is mainly determined by the general adoption of 1% of the paste after printing to tetrachloroethene (PCE) Determination of soaking for 30 minutes, 5 best, 1 worst. In general color paste, the blue-green good solvent fastness, less red, yellow, orange. 4. Fastness and resistance to uplift India: India pulling resistance of printing fastness determined mainly by the colorant generally increase by 1% 8% Germany paste pulled high forest after the Indian powder printing press 150-180 hot 15 -30 seconds measured, 5 the best, one worst. In general color paste, the blue-violet and yellow print fastness better resistance to pull, less red (even higher fastness of the red can only reach 4 or so), in which the pure green color paste is not used for Stubbs India, usually selected paired green to yellow and blue print drawing printing. 5. Rubbing fastness: printing abrasion fastness mainly by adhesive (solid slurry Glue Etc.) decision, the general increase by 5% paste composition containing 15% solid slurry Printing Paste Wet and dry printing apparatus after the friction friction 100 back OK, five is best, one worst. The amount fixed in the adhesive under the conditions of the greater amount of fastness paste the worse the better the contrary; rubbing fastness of the good and bad little to do with color paste, so you can change the amount of adhesive to adjust the printing of friction in prison degrees, and even cross-linking agent can be added We are high quality suppliers, our products such as Metal USB Memory , China Mini USB Flash Drive for oversee buyer.
