Printing carpet stitching essentials

Production practice of printed carpet: the same dye formula is modulated twice, and the color paste cannot be completely consistent; The same can of color paste produced twice, can not produce completely consistent color; Additional orders cannot be guaranteed to be the same color as multiple batches.

During the construction of printed carpet paving, individual sales departments have encountered: When the carpet produced in the same batch is partially spliced in the same color normal direction, it is found that the color of the seam is slightly different, and individual serious cases even affect the site acceptance. What's the reason? How to avoid it? Here is a simple explanation for you:

First, although the printing carpet production equipment has a variety of automatic control systems, but when the huge equipment is running, the index parameters have a certain range of slow periodic fluctuations, such as temperature, humidity, pneumatic injection pressure, color paste viscosity, pH value and other parameters, these parameter fluctuations will directly affect the color consistency.

Second, after the printing carpet pattern is thousands of square meters, the production preparation section needs to moddle two barrels of pigments, cans or even more times, and the production and printing time takes more than 8 hours or even longer, but the temperature difference in the morning and evening, the chemical reaction of the barrel and the tank times and the reaction with the passage of the production time (the color paste is having a subtle chemical reaction at all times) will make the pigments slowly change. Reflected in the finished product, the color of the first 100 square meters and the last 100 square meters will be slightly inconsistent, the first hour and the last hour will be slightly inconsistent, and the larger the order and the longer the production time, the more difficult it is to avoid.

Printed carpet with the current equipment, process in the production of adjacent volume number (on the packaging label), the color should be the closest, even if there is a change is slow, continuous slight gradient; The farther apart the volumes are, the more likely there is to be a cumulative difference in color.

Summary, when printing carpet paving, try to use adjacent volume number splicing, the principle of common sense during construction, the larger the batch, the more to be in accordance with this principle of paving, otherwise it may cause splicing color differences; Secondly, once the pavement is casually cut, in case of differences, it will cause obstacles to subsequent adjustment and remediation, because the carpet suitable for splicing has been cut for it.
