The breakthrough and maturity of the melt-spun spandex production process is of great significance to eliminate outdated processes and equipment, improve resource utilization efficiency, protect and improve the environment, and promote sustainable economic and social development.
1. Water resource consumption:
The production process of melt-spun spandex does not use water resources, while the production of one ton of dry-spun spandex consumes a lot of water resources.
2. Solvent consumption:
Melt-spun spandex does not use solvents, the production process is clean, and no three wastes are generated. Harmful solvents such as DMAC and DMF need to be added in the production process of dry spinning spandex.
3. Solvent residue:
Melt-spun spandex does not add solvents, has no solvent residues, and is green and safe. Dry-spun spandex adds solvent volatilization and pollutes the atmosphere, and the fabric has solvent residues, which will damage the health of the human liver.
4. Cyclic degradable:
Today, the social reserves of waste chemical fiber textiles in my country continue to rise, and it is very urgent to solve the problem of waste textile recycling and reuse. Melt-spun spandex is environmentally friendly and degradable, which meets the development requirements of circular economy. Dry-spun spandex cannot be degraded, which increases environmental pressure. The use and promotion of melt-spun spandex provides a "green" solution for the development of circular economy in the recycled fiber industry.
5. Feel:
Melt-spun spandex is soft and delicate, with good resilience, bringing consumers a soft and comfortable wearing experience. Dry-spun spandex fabrics become stiff.
