The invention relates to a production process for linen bamboo fibers, spinnable linen bamboo fibers and bamboo
fiber yarns. The production process comprises the following steps: sawing a fresh bamboo into pieces according to a certain length and then respectively soaking the pieces in different biologic
softening solutions or cooking the pieces in specially prepared
softening solutions at high temperature; after cleaning the pieces, heating and airing the pieces, and then feeding the pieces into a bamboo mechanical splitting
system, thereby preparing the linen bamboo fibers;
processing the linen bamboo fibers into strip-shaped bamboo
fiber spindles; putting the strip-shaped bamboo
fiber spindles into an intelligent steam
cooker in turn, thereby degumming, bleaching and cleaning the strip-shaped bamboo fiber spindles; after
drying the strip-shaped bamboo fiber spindles, opening and removing impurities, thereby acquiring the spinnable linen bamboo fibers; and sending the spinnable linen bamboo fibers into a
yarn-forming integrated
system, and performing the processes of opening, cotton-blending,
carding, drawing and
yarn-forming, thereby finally acquiring the bamboo fiber yarns. The bamboo fibers prepared by using the production process are linen, longer, thinner, more uniform and softer. The average
fineness of the bamboo fibers can reach 400-600 metric counts. The bamboo fibers can be purely spun or fully blended with fibers such as cotton, linen, and the like.
