Quality Influencing Factors of Dye Sublimation Printing Technology

Ink
Sublimation Printing ink is the key material of dye sublimation printing technology which is mainly composed by the disperse dyes, connecting materials, solvents and a few additives.
The dye must have a good sublimation transferability and permeability to reach a certain fastness index. Molecular weight is 23O ~ 380 and sublimation temperature is 180 ℃ ~ 240 ℃. The common printing dye is anthraquinone dyes, azo dyes, and cationic dyes(cationic leveling agent).
Temperature and time
Dye sublimation printing technology requires temperature control in the range of 180 ℃ ~ 230 ℃, the time is about 10 ~ 30s, and at the same time pay attention to the reasonable deployment of temperature and time.

Pressure
Pressure is also one of the important parameters of dye-sublimation printing technology. If the pressure is appropriate, the gap between the flat fabric and transfer paper are suitable, the transfer coloring effect will be good with a clear pattern and smooth lines.

Other factors
In addition to ink, temperature, time and pressure, there are some matters during actual production process will affect the quality of sublimation printing.
Firstly, you should choose the printing paper from a big supplier with high quality and high credibility.
Secondly, it is recognized that the color difference of the dye ink before printing (the pattern on the transfer paper before heat application) and after printing (pattern transferred to the fabric) are big. Generally speaking, the dye ink looks dark and dull before printing. It relies on high-temperature of about 200 ℃ to restore true color. 
Finally, you should ensure that the hot surface, the transfer paper and the substrate surface close to each other without any gap while thermal transfer. Otherwise, a blurred image may appear.

BMA to invest $204 mil to spur ramp up at Queensland coking coal plant

BHP Billiton Mitsubishi Alliance will invest $204 million to speed up the process of ramping up production at its new Caval Ridge coking coal processing plant in Queensland, Australia, to 10 million mt/year, BHP Billiton said Friday.  The investment will go towards a 11 km overland conveyor system, the Caval Ridge Southern Circuit, which is termed as the "missing link" to transport coal from the Peak Downs Mine to the Coal Handling Preparation Plant at the nearby Caval Ridge mine, said BHP Billiton president operations, Minerals Australia, Mike Henry.  "This investment furthers our productivity agenda, reduces costs, releases latent equipment capacity, and strengthens our coal business' global competitiveness," the company said.  It will result in the Caval Ridge preparation plant increasing its throughput to reach its 10 million mt/year capacity, it added.  Construction of the project is scheduled to begin mid-2017 and take 18 months to complete.  In addition t...

The General Steps for Examining the Quality of The Appearance of Textile

The contents for examining To examine the quality of the appearance of textile starts from the accuracy of colors The inspection process is as follows: to test the accuracy of color; raw materials, weaving defects, defect inspection and defect treatment before dyeing defect and finishing defects, in accordance with the standard requirements to determine whether to cut off or drop size. When the color accuracy test is in dispute, the dispute can be settled down according to the measurement results of the electronic color matching system. 1) Material defects The raw materials have obvious defects like big belly yarn evenness is not uniform, there are too many joints, yarn, fiber, silk, specific bad Spandex Covered Yarn Quality, blended yarn uneven mixing and so on, which are likely to cause the fabric etc.. 2) Weaving defects Weaving defects come from many aspects, such as equipment itself, raw materials, environment, temperature and humidity, operator technical level, fabric structu...
