Non-woven special equipment accessories
Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.
Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.
The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.
Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.

According to reports, from January to August, the country’s output of coke increased by 20.1% year-on-year, which was 3.8 percentage points higher than the national increase in pig iron production. Among them, the increase in coke production in July has dropped to 16.9%, while the increase in pig iron production in July fell to 13.2%, but the increase in coke is still 3.7 percentage points higher.
Huang Jingan said that according to forecast, the total crude steel production this year is expected to reach 480 million tons, which is an increase of about 14% from the previous year. Therefore, the market risk of coke has become apparent, and the coking industry must adapt to the market demand in order to achieve production and sales, and control the excessive growth of coke production. “Since the second half of last year, coke prices have been adjusted several times, and the economic benefits of coking enterprises have increased. However, a number of construction projects for coke ovens that were temporarily suspended have begun to start construction, together with a batch of iron and steel co-operative enterprises supporting coke ovens and large-scale coal group industrial chain extensions. The construction of coke ovens has accelerated the increase of new production capacity, which has increased the market risk of the coking industry, said Huang Jingan.
The potential pressure in the coking industry has not been solved
Jin Qiang, chairman of the China Coking Industry Association, said on September 20 at the China Iron and Steel Raw Fuel Market Summit that although a number of outdated small coke ovens have been eliminated this year, the increase in new coke oven capacity still exceeds the elimination of outdated small aircraft coke. The amount of capacity reduction. Therefore, the coking industry still faces potential pressures of oversupply in the future.
