The invention provides a method and
system for
regenerating fibers from waste textiles, and relates to the technical field of
textile equipment. The method comprises the following steps: firstly, slitting a waste
textile raw material through a vertical crossing slitting unit to obtain a cloth piece with a preset size; then, auxiliary agent spraying and steam
ageing treatment are carried out on the cloth pieces, so that cohesive force between fibers is reduced; then carrying out flexible pretreatment, gradually loosening a warp and
weft yarn structure through a needling device, and carrying out preliminary opening; then, through the multi-stage opening and
impurity removal step, the materials are converted into a
single fiber state in combination with a
material distribution mechanism; the fibers are atomized and humidified in the conveying or storage process so as to maintain the
water content and the strength; then fully
carding through a
carding and
fiber separating
machine, and separating the single fibers into at least three types of long fibers, medium and short fibers and ultra-short
fiber components according to the difference between the
fiber length and aerodynamic characteristics; and finally, respectively collecting and packaging the fibers with different length components. According to the invention, high-valued cyclic utilization of the waste textiles is realized.
