Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
Batik printing, also known as wax printing, is distinguished from imitation batik or imitation wax printing, sometimes called true batik or real wax printing. The main style characteristic of batik cloth is the natural and lively exquisite wax pattern and the consistent printing effect of the front and back. This is also an important difference between the real wax printing and the imitation wax printing. The molten wax liquid as a printing medium is the key to obtaining the above-mentioned style characteristics. The wax liquid is printed on the fabric and cooled by a water bath to form a wax film, which has an excellent anti-staining effect on the indigo main color, and can be made into a wax-like effect similar to ice. In addition, the batik printing in the full sense also includes the butt-printing of other sub-patterns and indigo-based patterns (wax-printing), so-called secondary printing. In addition, it is necessary to ensure the complete offset of many secondary flower patterns, that is, to obtain the printing effect of the front and back sides in a single-sided printing manner. The secondary printing reflects the complexity of the batik printing process technology, which is another key technology for batik printing. 1 secondary printing 1.1 secondary printing concept batik printing process
Pure cotton mercerized semi-products → whole weft tenter → printing wax → anti-dyeing indigo → waxing → wax pattern coloring → wax removal → secondary weft
As can be seen from the batik printing production process, unlike ordinary printing or imitation batik printing, batik printing has to undergo two different printing processes.
The first is batik, which consists of two processes: printing wax and dyeing. Before indigo dyeing, the fabric is first printed with wax, even if the liquid wax is transferred to the cotton fabric to form a pattern wax film, which is done by a wax printer. As mentioned above, the floral wax film on the fabric has excellent anti-staining and cracking properties, which is the key to ensuring the batik printing style. Followed by the printing, that is, the printing of the secondary color on the wax printing fabric dyed with the indigo main color pattern, so that the color is more abundant. This is the second print in batik printing, so it is called a secondary print.
