Standard Moisture Regain Equations for Raw Flax Weight Settlement
Standard moisture regain formulas adjust raw flax invoice mass by converting weighed tonnage into bone-dry weight plus contractual water allowances.
Long Flax
Material Category
Premium linen textiles require high-aspect-ratio natural fibers that have been extracted from the flax plant through carefully controlled scutching and hackling processes. This long flax, also known as line flax, consists of parallel fiber bundles that typically measure from sixty to ninety centimeters in length. The material is graded based on its color, strength, and fineness before being sent to the spinning mill.
This grade of fiber represents the highest quality tier in linen production, commanding a higher price than shorter by-products like tow. Its long staple length allows spinners to produce fine counts of yarn with high tensile strength.
Processing Advantage
Long fibers are essential for producing fine, high-tenacity yarns using the wet-spinning method. When spun, long flax generates a smooth yarn with minimal hairiness, which is highly desirable for luxury apparel and fine household linens. The parallel alignment of these fibers allows for even drafting during the spinning process, resulting in a consistent yarn count.
This consistency reduces yarn breakage rates on the high-speed looms during weaving.
Quality Classification
Classification systems categorize this material according to regional grading standards. French and Belgian line flax are compared against Chinese domestic grades in purchasing reports. Spinning yield is recorded for each batch.
This rigorous grading ensures the final cloth meets global apparel standards.
