Optimizing Shed Height Settings for Air Jet Linen Fabric Construction
Optimizing air jet linen shedding requires asymmetric harness levelling at 26 millimetres to balance relay nozzle clearance with tension limits.
Pilling
Surface Degradation
Fabric wear results in the formation of small, tangled bundles of fibres on the surface of woven or knitted textiles. This phenomenon, known as pilling, occurs when loose fibre ends migrate to the fabric surface and entangle during friction or laundering. For linen fabrics, which are composed of long, strong flax fibres, this defect is less common than in synthetic blends but still requires testing.
Evaluation Method
Laboratory testing uses abrasion machines, such as the Martindale tester, to subject fabric specimens to controlled multi-directional rubbing. After a set number of cycles, technicians grade the specimen against visual standards on a scale from one to five, where five represents no change. High pilling susceptibility in a linen fabric usually points to the use of short, low-quality flax fibres or insufficient yarn twist.
Understanding the cause of the surface fiber migration allows weaving mills to adjust their finishing processes, such as applying enzymes to stabilize the yarn structure and resist fuzz formation.
Consumer Performance
Aesthetic appeal and tactile comfort of apparel fabrics depend heavily on resisting surface changes over long periods of wear. Woven linen that exhibits low pilling maintains its smooth texture and premium appearance through repeated washing cycles. This durability is a primary factor in the selection of flax-based fabrics for high-end home textiles and apparel.
