Fibre Processing
Yarn production processes utilize specialized machinery to draw and twist long natural fibres into strong high quality threads. Textile manufacturers employ long staple spinning to process flax fibres that are too long for standard cotton machinery. This process is the standard method for producing fine linen yarn used in high end fabrics.
The mill records the process parameters on the spinning routing sheet for each batch.
Draft System
The equipment used in this layout features a wider ratch or distance between the drafting rollers to accommodate the long flax fibres. Raw flax must undergo combing and hackling to parallelize the fibres before they enter the spinning frame. In Chinese wet spinning mills, these long fibres pass through a hot water bath before reaching the rollers to soften the natural pectins.
This treatment allows the individual fibres to slide past each other during drafting to create a finer thread. It also ensures that the final spun yarn has a high level of fiber alignment to increase structural strength.
Quality Output
Weft and warp yarns produced by this process exhibit higher tensile strength and lower hairiness than short fibre yarns. When long staple spinning is executed correctly, the yarn will have fewer slubs and thin places to cause breaks on the loom. Buyers specify this production method for linens that require a smooth surface and high durability.
