Abstract
Articles are prepared from paper containing different types of fibers. In a granulation step, bagasse is pulverized to produce a sugar cane pulp powder of granules. In a pulping process, pulp is produced from Manila hemp. In a mixing step, sugar cane pulp powder, and the pulp produced in preceding steps, are mixed. In the papermaking process, Japanese washi paper is produced by using a mixture of pulp powder and pulp. In a slitting process, the produced Japanese washi paper is slit. In a twisting process, the slit Japanese washi paper yarn is twisted to produce a paper yarn.
