PTA And Polyester Operating Rate Scissors Gap Narrowed Accumulation Inventory Continues

At the end of June, the PTA plant. Operating rate At 68%, the scissors gap narrowed by 8%, compared with the level of polyester 76%, which prompted PTA to enter the accumulating inventory stage. In mid July, the market rumors that the 1 million 500 thousand ton plant of Xiang Lu Petrochemical Company will be restarted, is still unknown, but the current polyester production profit has shrunk, some production loss has reached 500 - 600 yuan / ton. polyester Link operating rate still has room for further decline, which will accelerate. PTA The process of accumulating inventory.

Therefore, unless there is a parking repair operation in the big PTA plant in July, otherwise, the PTA futures will continue to show a weak pattern after falling below the 5000 integer mark in the background of the weak oscillation of crude oil prices and the loose supply and demand of PX and PTA.

With the rapid development of the individuation and quality of textile products, the quality requirements of the downstream enterprises of cotton textile have improved. Due to cost and other factors, cotton textile enterprises will consider making some scientific and reasonable adjustment in raw material blending with cotton spinning. Therefore, Zhejiang Jinfeng Textile Machinery Co., Ltd. has developed the JZX - "5" comb, sawtooth combined high efficiency comber comb. According to the performance and sawtooth characteristics of the comb pin, the circular comb design of the high efficiency cotton comber is optimized and the carding ability is further improved.

However, combing fiber needs combing force, and the carding force is not enough, which will cause the fiber bundles not to open, resulting in fiber bundles. Too much combing force will lead to fiber damage, increase short staple, aggravate the abrasion of the needle teeth, even break the needle and break the teeth, and increase the energy consumption of the equipment. Therefore, the design of the circular needle and saw tooth has been greatly improved. The round comb needles ensure the sharpness and roughness of the front end, and ensure the taper of the rear end. The saw tooth piece adopts the technology of stamping and grinding on both sides of the tooth surface to ensure the smooth tooth tip, tooth root and tooth surface.

At the same time, in order to adapt to the high speed and large quantitative process requirements, avoid inserting, loosening and finishing of the front row sawtooth puncture cotton layer, and better integrate the advantages of the needle cylinder and the sawtooth cylinder to ensure the best puncture effect. The needle tooth height of the needle bar and the tooth piece is deep and shallow in the front row, which reduces the filling of the fiber to the cylinder and improves the carding effect of the fiber and cylinder. Such a cylinder design has consciously divided the tin forest into two regions, ensuring the carding quality of high-speed movement, and also suitable for various types of cotton comber mainframe.

With the increasing demand for semi finished products and yarn in cotton textile enterprises, how to meet the requirements of users and improve the quality and quality of products is a systematic project. Zhejiang Jinfeng should further improve the quality management network, strengthen the quality control points of the production process, and do well in the production.
