Fibre Categorization
Long line filasse denotes the highest quality of retted flax fibre extracted during the initial mechanical separation from the stalk. This material consists of continuous parallel filaments that maintain their original biological length rather than being broken into short segments. Mills sort the product by measuring the average strand length and assessing the absence of shive or residual woody particles.
Export documentation records these grades based on tensile strength and clean appearance.
Spinning Specification
The mill processes long line filasse by feeding the untangled bundles into a series of hackling machines to align the fibres for fine yarn production. Uniformity in strand thickness dictates the setting of the drawing frames throughout the preparation stage. Consistent length prevents excessive waste during the combing phase while ensuring that the resulting yarn possesses high durability.
Technicians verify the weight per unit of length to confirm the material meets the input requirements for high count spinning.
Quality Standard
Buyers purchase this grade under specific contractual terms that define the maximum allowable moisture content and foreign matter contamination. These agreements set the threshold for the fineness of the fibre bundles delivered to the processing site. Independent testing verifies these parameters against the agreed sample before the manufacturer accepts the shipment into the warehouse.
The inherent length of the individual fibres determines the final price paid for each batch of raw material.
