  Abstract

In order to increase the product diversity and wide application of cellulose acetate fiber in the field of nonwoven filtration, combined with the rapid development of green fiber, the response surface methodology (RSM) was used to optimize the parameters of cellulose acetate/polylactic acid (CA/PLA) nonwoven in the preparation process. The hybrid ratio, linear density, and fiber length of CA fiber were selected to optimize the preparation process of nonwovens with filtration efficiency and tensile strength as response values. The results showed that the hybrid ratio was 80%, the linear density was 3.33dtex, and the fiber length was 46 mm. Under this process, the filtration efficiency of CA/PLA nonwoven is 35.74%, longitudinal tensile strength is 0.734 MPa, and transverse tensile strength is 1.782 MPa, which is close to the theoretical value, indicating that RSM has application value. It can provide a theoretical basis for the preparation parameters of nonwovens with excellent tensile strength and filtration efficiency at the same time. In addition, the air permeability, filtration resistance, and surface morphology of CA/PLA nonwovens were tested. It was found that the effect of hybrid ratio on air permeability and filtration resistance is not obvious, but linear density and fiber length are significant, and CA/PLA nonwovens are three-dimensional structures with disorderly surfaces, which are conducive to filtering dust, particles, and other impurities in the air.
