Description

Technical Field

[0002] With the development of cigarette machinery and equipment and the increasing demand for tobacco, the number of waste filters caused by the failure of cigarette machinery and equipment is also increasing. The main part of the filter core of the scrapped cigarette core is composed of cellulose acetate. After the filter core is heated, the slag liquid is discharged, and the remaining fiber is an important raw material for paper. Acetate fiber is not easy to catch fire and can be used to make textiles, cigarette filters, sheet bases, plastic products, etc. Acetate filaments are similar to silk among chemical fibers, with elegant luster, bright dyeing, strong dyeing fastness, soft and smooth feel, light texture, low regain, good elasticity, not easy to wrinkle, and good drape, thermoplasticity, and dimensional stability. However, the traditional solution is to manually separate and incinerate waste filters.
