Abstract: A dust-proof fabric having an excellent dust-collecting efficiency and dust-preventing property including a plurality of filament yarns having a thickness of 20 to 400 denier and consisting of a plurality of individual filaments having a denier of 3.5 or less. The fabric has a number of pores formed therein and exhibits an air permeability of 0.3 to 10 ml/cm.sup.2 /sec. In the fabric, the proportion of the integrated volume of pores having a size of 43 .mu.m or more to the entire integrated volume of all the pores in the fabric is 40% or less.

Abstract: A high population density of closed C shaped cellulose acetate filament can now be reliably produced. The closed C filaments are made from a spinneret having a. substantially D shaped orifice under particular processing conditions depending on the dpf of the filament, the theta angle of the D shaped orifice, and dope temperature. The process can make a high population count of closed C shaped fibers in a. tow band, and article are not provided having the high population density of closed C shaped fibers.
