Weft Compaction
Reed movement toward the fell of the cloth at the point of shed closure determines the final density of the woven fabric. During this phase, beat-up compression forces the newly inserted weft thread into the existing structure of the linen. This action establishes the picks per centimetre as specified in the production contract.
Yarn Interaction
Frictional resistance between the warp and weft yarns opposes the movement of the reed as it travels toward the fell. In high density linen weaving, beat-up compression must overcome the thickness of the flax fibres to seat the yarn firmly. The loom settings for reed timing and stroke length dictate the intensity of this pressure.
If the compression is too low, the fabric exhibits an uneven texture known as reed marks or variations in weft spacing. Conversely, excessive force can damage the warp yarns or cause the weft to buckle within the weave structure. Maintaining a consistent pressure ensures that the fabric weight remains within the tolerances required for export quality.
Machine Setting
Final fabric stability relies on the uniform application of this mechanical force across the entire width of the loom. Variations in the reed motion lead to narrow strips of higher or lower density that become visible after the finishing process. The physical displacement of the yarn during this phase creates the specific hand and drape of the finished linen cloth.
