Batik printing flaw analysis and solutions
Cotton batik printed fabrics popular for its unique style favored by foreign customers, thus the dye have been started around the real wax line. Actual production, as batik printing products processing operations and more demanding process, to make batik products, product defect rate has been high and low grade of products, affecting the economic benefits of the manufacturer. In order to improve product quality, the quality of this article on the common problems are analyzed.
HC screen Special printing network Cotton Batik Printing Fabric with its unique style of popular favor foreign customers, so in recent years have been started around the real wax printing and dyeing production line. Actual production, because of batik Printing Multi-product processing operations, process high demand products to batik product defect rate has been high and low grade of products, greatly affected the economic benefits of the manufacturer. In order to improve product quality, the quality of our common problems are analyzed.
Batik printing Common Problems and Solutions 1 bad wax pattern 1.1 composition of wax In the batik process, the composition of liquid wax material there are many. Since the brittleness and flexibility of different materials is different, so flexibility is not made of wax, like, fell after wax wax patterns produced different results, and some stout, some thin, some are too fragile, even dewaxing defects caused by batik. According to the physical properties of polymer materials additivity?, We have the components of the appropriate combination of wax, rosin and auxiliary A final component used wax coated cotton cloth, the wax produced by the fall of wax patterns slender, natural effective .
1.2 boil wax liquid temperature
Rosin and wax additives as component A, the wax liquid temperature is 160 produced wax, wax best; when the system temperature is below 160 wax, the wax is better the flexibility, fall when the wax is not easy cracking, but difficult to form a wax pattern; if the temperature is too high, such as 180 wax, the wax is too brittle, breaking easily wax from the fabric surface when the wax off, wax pattern thick is short, easy to cause dye defect.
2 boil time of liquid wax
Boil at 160oC wax, if time is too short boil wax, wax in the cloth surface, good flexibility, difficult to produce when wrestling wax pattern wax; if boiled too long wax, the wax more brittle produced by the fall of wax generated from the wax pattern thick is short, easy to create from the drop-cloth stained gel spots. The test confirmed that the time at 160 for 6h suitable wax boil.
2.1 cooling wax on canvas
Water cooling and air-cooled two cooling methods. The advantages of saving water Energy , Equipment investment, but the wax pattern poor results, mainly for the lines clear, light in color and not bright; Air France is in the dry state because the fabric under the wax is cold to freezing, Oil on wax flexibility and brittleness appropriate, the resulting wax pattern slender, good dyeing effect, but there is energy consumption, equipment investment shortcomings. Improve product quality, the best cooling method used.
2.2 wax drop Drop cloth when the wax patterns directly affect the severity of the effect. In general, fall heavier wax, the wax pattern appears more, but some coarse, even falling down the wax from the fabric surface, resulting in staining defect; if wrestling wax too light, then the wax pattern may appear less , in particular, does not directly fall of the fabric side of wax patterns appear less, not even. So good to be thrown out of the wax pattern, the fabric sides of the wax patterns are better, some good wrestling to control the wax. 2.2 The color is not bright
2.3 pre-treatment capillary effect, degree of white As the wax pattern
smaller, but also demands deep and bright colors, so they requested that the full pre-treatment, the fabric of the capillary effect and whiteness is higher. If the pre-treatment capillary effect is not good, the batik fabric with liquid when the low, light staining. In order to increase the brightness and color fabric bleach should be strengthened, higher whiteness, then the more vivid coloring. Test confirmed that the capillary effect batik printed fabrics must be more than 12cm/30min, so as to achieve the objective of a rich ruby color.
2.3 Dyes Batik printed fabric requirements unique pattern, color and nuanced, it should be used in the dyeing dyes easily dyed dark. As the batik cloth when the surface of wax, if the dyeing temperature is too high, the wax will become soft, and even melted wax patterns affect results, this should be selected low temperature dyes. Common ice cold dye dye, x-type reactive dyes. Test confirmed that the ice the most suitable dye as batik dyes, can satisfy the low temperature dyeing, but also ensures a rich ruby color. K type reactive dyes in the selection of the secondary printing, the need to focus on the surface of the wax cloth before printing must go to the net, steaming temperature to control the well.
2.4 wax method of cooling
To make batik fabric color nuanced, except with capillary effect, whiteness, dye related, but also to the fabric before dyeing the wet and dry conditions. If the fabric wax, the wax liquid cooling using water cooling method, the fabric contact with water, wet, wet impregnation liquor and the fabric, dye into the fabric of less, that is, the color of clear light wax pattern; if the wax is cooled by air to liquid cooling , then the fabric is dry before the wax, dried impregnated fabric dye, wax fabric with the dye pattern Office quantity, color wax pattern is deep, Oil on wax pattern better effect. Therefore, cooling method should be used to cool the wax.
