Calibrating Flax Fibre Intake Standards for Dry Spinning
Dry spinning flax intake standards require strict bundle fineness under 2.2 tex, residual shive below 0.8 percent, and 11 percent target moisture regain.
Dressed Short Line
Fiber Classification
Cleansed and combed flax fibres of shorter staple length obtained during the final stages of the hackling process represent a distinct raw material category. In the yarn industry, dressed short line is known for its moderate length and relative cleanliness compared to raw tow. This grade is typically documented in the comb-house yield report before being routed to specific spinning lines.
Milling Process
Production starts when the scutched flax is processed through a series of increasingly fine pins on the hackling machine to separate the long line strands. While the longest strands continue to the drafting rollers, the shorter fibres are combed out and sorted to form the dressed short line. This mechanical processing removes shive and any unretted bark fragments to improve the purity of the stock.
Spinning Allocation
Spinning mills utilize this shorter material for medium to coarse yarns that do not require the high tenacity of long line fibres. Because the shorter fibres have a higher variation in length, they are frequently blended with other batches or subjected to rotor spinning. The yarn produced from dressed short line is commonly used in heavier utility fabrics such as home textiles and industrial coverings.
This selection ensures that the premium long line fibres are reserved for high-count apparel yarns where tensile uniformity is paramount.
