Zhejiang Jingpeng Zirconium Industry Technology Co., LTD., revealed the status of woven bag drawing blade in woven bag production

Woven bags believe that everyone has seen, also known as snakeskin bags, is a good helper to pack large things.

A type of plastic bag used for packing. In fact, look carefully, you will find that it is composed of a lot of filaments, here the filaments, you need to use the process of drawing, in the process of drawing need to use the woven bag drawing blade, this is specifically for the woven bag blade, in the woven bag drawing process plays a key role.

In daily life, woven bags are widely used, such as quilts and clothes, and the types, sizes and materials are differentiated.

Zhejiang Jingpeng zirconium Industry Technology Co., LTD., said that the most common plastic woven bags, it is through plastic flat wire, plastic knitting industry referred to as: Flat silk, also known as cutting fiber, is the basic material for the production of plastic woven fabrics. Flat silk is made of specific varieties of polypropylene, polyethylene resin by melting and extrusion into a film, and then longitudinally-cut into strips, which are heated and drawn at the same time after shaping, and finally wound into flat silk spindle for weaving woven fabrics.

The flat wire process is used, flat wire process, also known as yarn making process, it is the first process of plastic braid production, is also the most important process. These include: Raw material modification, blending, coloring, filling, preparation, anti-aging, anti-degradation problems, temperature, pressure and flow control in the extrusion process and rheological behavior in the extrusion process, power consumption, yield problems, traction ratio, blowout ratio, drafting ratio, crystallization cooling, orientation, heat treatment finalization problems, forming in the winding process and quality detection of spindle and other technical problems.

According to the film forming method, the production process of flat silk can be divided into two types: tube film and flat film; according to the cooling method after film forming, it can be divided into air cooling, water cooling and intercooling; according to the draft heating method, it can be divided into hot plate, hot roll and hot air; according to the spindle winding, it can be divided into concentrated cycloid winding, single spindle moment motor winding and magnetic moment winding. It can be seen that the production process is more complex.
