The supply of recycled PET is reduced, and the new material is appropriately replaced by the recycled material

Introduction: under the dual influence of domestic environmental protection and import ban, the supply of subsequent recycled PET will be reduced. At present, the price difference between recycled polyester products and new materials is narrow, and there may be a change in purchasing tendency in the cross demand field of terminal. However, the production capacity of regenerated chemical fiber is obviously excessive, and the supply side forces the industry to enter the adjustment cycle. The recycling space of waste polyester packaging products and waste polyester textiles is still huge. With the gradual establishment of domestic recycling system and the gradual normalization of enterprise development, combined with the way of going out, the medium and long-term renewable polyester industry will gradually upgrade and integrate, and achieve healthy development. In the short term, there is a moderate reverse substitution of new materials for recycled materials, but the quantity is limited, which is not enough to have a significant impact on the original polyester.

What are the main aspects of substitution of new materials for returned materials?

Different from other products produced by mixing recycled plastics and new materials, recycled PET is degraded to produce recycled chemical fiber. In other words, the replacement of recycled PET in the field of polyester bottle sheet plastic application is very little. In the field of chemical fiber, the new material of recycled PET bottle sheet is polyester chip. Although the viscosity and melting point of the two are obviously different, they are used to produce polyester fiber. Some recycled chemical fiber enterprises can purchase appropriate amount of polyester chips for mixed use or separate production. In addition, as the substitute of raw material polyester fiber, the terminal demand of recycled polyester products has a certain intersection, mainly in the low-end market.

Recycled chemical fiber is still the main demand of recycled PET, and cotton spinning accounts for a large proportion, as long as it is used for spinning. There is a substitution relationship between regenerated common fiber and primary polyester staple fiber. At present, a few manufacturers of regenerated fiber yarn have switched to polyester staple fiber production. With the increase of the price of recycled products, the anti substitution of polyester staple fiber for imitation has a tendency to expand.

The filling field is mainly hollow products, and the proportion of regenerated hollow products accounts for more than 80%. Due to certain IPA content in recycled PET bottle chips, the viscosity is relatively high, and the product stiffness is good, which has a good occupation of filling in some fields such as mattresses, plush toys and other industries, and the original products are not suitable for use. Therefore, as a leading product in the field of filling, the market of renewable hollow is relatively independent, and the space for the replacement of primary hollow is relatively limited.

In terms of non-woven fabric industry, the downstream is mainly used in geotextile, linoleum base cloth and other fields, but these fields have not very strict product requirements. In recent years, most of them are dominated by recycled products, and the share of original products is not much. As long as the price of renewable products is lower than that of original products, the downstream purchasing tendency will remain unchanged.

Recycled filament is the smallest category of recycled chemical fiber. It can produce cashmere fabrics with low quality requirements, or can be used as base silk in the field of circular knitting machine. Production elastic belt, curtain, sand release, as well as blanket, carpet and other products. Since 2014, there have been continuous withdrawal of regenerated filament enterprises, and the production capacity has been shrinking. At present, the output of regenerated filament is less than one twentieth of that of polyester filament, and some manufacturers produce and use it by themselves, so the original products have little significance to replace the regenerated filament.

There is a moderate reverse substitution of new materials for recycled materials, but the quantity is limited, which is not enough to have a great impact on the original polyester.

According to Zhuo Chuang research, at present, recycled chemical fiber manufacturers absorb polyester chips at a low price to prepare for unexpected needs. However, the proportion of recycled common fiber manufacturers is more inclined to foam products with low price, and the purchase of new materials is weak. In the future, with the continuous shortage of recycled PET supply, the new polyester chips will form a certain reverse substitution for the recycled bottle chips, and the polyester staple fiber will also extrude the application of regenerated common fiber in cotton spinning field, but the quantity is relatively limited. It is necessary for recycled polyester manufacturers to focus on the improvement of domestic recovery rate, industrial chain development and going out.

In order to safeguard the national ecological civilization construction and system reform of ecological civilization, promote the reform of solid waste import management system, promote the harmless and resource utilization of domestic solid waste, and protect the ecological environment safety and the people's health, in July, the Chinese government implemented the implementation plan of forbidding foreign garbage to enter the country and promoting the reform of solid waste import management system to prohibit foreign garbage Entry.

China's domestic recycling of recycled PET can not meet the demand of recycled chemical fiber enterprises. With the vigorous promotion of waste prohibition and environmental protection, China's Recycled PET supply is in short supply, and the price is soaring. Driven by this, the price of recycled chemical fiber is also rising.
