Title:
セルロース繊維と無機粒子の複合繊維およびその製造方法
Document Type and Number:
Japanese Patent JP7123178
Kind Code:
B2
Abstract:
The present invention aims to provide complex fibers comprising a cellulose fiber strongly covered by a lot of inorganic particles on its surface. In the present invention, an excellent complex fiber of a cellulose fiber with inorganic particles can be prepared on the basis of the value of (D50 - D10) / D50 calculated from the particle size distribution of (a) or (b) below: (a) the filtrate obtained by filtering an aqueous suspension of the complex fiber at a solids content of 0.1 % through a 60-mesh sieve (having an opening of 250 µm); or (b) the fraction corresponding to an effluent volume (L) of 18.51 to 19.50 and an efflux time (sec) of 37.4 to 48.0 when an aqueous suspension of the complex fiber at a solids content of 0.3 % is classified using a fiber classification analyzer under the conditions of a flow rate of 5.7 L/min, a water temperature of 25 ± 1 °C, and a total effluent volume of 22 L.
