A SPINNING METHOD

摘要

A spinning method comprising: in a drafting area of a ring spinning-frame, introducing two parallel staple roving (a, a') unwinded from roving bobbin into draft area formed by back roll (2), rear leather roller (2'), middle roll (3), middle leather roller (3'), apron (4),front roll (5) and front leather roller (5) through guiding tunnel (1) to draw the roving; feeding parallelly two filaments from the end of the front roll through positioning guide or guide wheel. The two filaments (b, b') and the two roving (a, a') are parallel. The filament (b) and the roving (a), the filament (b') and the roving (a') join together after passing front nip. After the two drawn roving (a, a') and the two filaments (b, b') are outputted from front nip, they are inputted to twisting triangle area and winded into spun yarn bobbin (7) through guide (6).
