Real wax printing technology is introduced into our country in 1996. With our traditional hand batik completely different. Xing Industry & Trade Co., Ltd. Qingdao and the requirements under the product, developed a new alternative to paint PDT rosin and double-sided multi-color rotary screen printing machine, create a new batik process.
HC screen Special printing network Real wax print technology is introduced into our country in 1996. With our traditional hand batik completely different, real wax printed cloth all mechanized production, wax printing cloth is to natural rosin melted, reaching around 170 (temperature according to the proportion of new and old wax be) printed cloth double surface, and then dye main color, thrown wax pattern, alkaline cleaning wax pattern, then dyed a variety of colored lines. Well after the wax pattern, wax rope back wash at room temperature, left in the middle of the cloth and yarn rosin, caustic soda must be added after warming up multi-channel rope washing machine washing. To rosin saponification with caustic soda at high temperature and dissolved in water to wash cloth. This production process caused serious water pollution. Wash the batik cloth, in the back once again with the rotary parts of wax Printing machine Penetration Printing Can achieve double flowering. Penetration Printing Gray hair before treatment required to achieve the penetration effect of high efficiency, to achieve consistent double-sided color. Industry and Trade Co., Ltd. Qingdao Hexing
According to product requirements, developed a new alternative to rosin PDT Paint And double-sided multi-color rotary screen printing machine, create a new batik process.
1, PDT new paint (a wax method)
1.1PDT coating composition and use of
PDT main component is sodium silicate paint (commonly known as sodium silicate) as the main raw materials and various additives prepared from the use of the product is a colorless thick liquid 400Be.
Instead of rosin with PDT, in the double-sided printing machine to print designs, the design of space contracted main color. Corrugated machine with a dedicated roll out the different styles of cracks. Horizontal and vertical thickness can be staggered, to dye a variety of colored lines. Use of PDT as paint can make hair wax pattern, Korea currently can not make hair with rosin is like wax pattern effect.
1.2 Process Printed PDT dye main color paint corrugated pattern dyeing joint width washing machine (return PDT) tenter double-sided multi-color printing paper fight. The production of new paint
1.3PDT Above it is clear that this process is short, the first printing PDT coating at room temperature, eliminating the need for rosin-based wax process, saving a lot of Energy . If the two conventional wax printing production line, to be equipped with 800 000 kcal oil boiler to meet the production needs, must also be used after printing rosin refrigerator, cold roll by more than just salt water cooling temperature drop cloth can be dry. PDT with double-sided color printing under the printing machine into the cloth, on a cloth by the infrared pre-reheat and air drying. Drop cloth can be dry.
1.4 dye main color process requirements
Dye main color dyeing machine using the best IBN. Because PDT coating easily dissolved in water, dry cloth dyeing, fixing the best dry cloth.
1.5 production hair-like color patterns
Printed color rosin can only make a rough pattern, hair wax pattern is not make to the. Printed PDT coating developed using our combined corrugated dyeing machine, you can crack one-time roll out thin. To make direct dyeing hair-like color pattern. After eliminating the Indian rope thrown rosin wax pattern, open rate, alkaline cleaning wax patterns and other processes.
1.6PDT paint washing and recycling
PDT coating easily dissolved in water. Therefore, multi-color cell staining pattern width washing machine, will be announced in 90 hot water to melt the surface of washed PDT coating without any additives, fabric is very clean, washing with hot water after the expansion evaporation Recycling PDT coating, process simple, low cost, pollution-free. Solve the printing rosin, rosin saponification with caustic soda and pollution.
