Fabric Width
Narrowing happens when tension during mechanical processing pulls the side borders of a textile inward. Edge draw-in describes the permanent reduction in width that occurs during the wet finishing stages of linen production. This reduction forces a loss of surface area that manufacturers must calculate before the initial cutting of the grey cloth.
A shrinkage allowance accounts for this phenomenon to ensure the final garment dimensions remain consistent with the specifications provided by the purchaser. Constant monitoring of tension settings on the tentering machine prevents excessive contraction beyond the acceptable range defined in the contract.
Tension Control
Processing machinery requires precise calibration to maintain the geometric stability of the fabric. Operators adjust the overfeed percentage to compensate for the natural tendency of linen fibres to contract when moisture levels fluctuate during drying. Inadequate regulation leads to a non-uniform width that compromises the integrity of the finished bolts.
Variations in fibre maturity or spinning consistency also influence the degree of contraction, requiring a dynamic response from the production team.
Contract Compliance
Quality control protocols mandate the recording of the final width for every production lot to verify adherence to supply agreements. Inspectors measure the distance between the two selvages at multiple intervals across the length of the material. A certificate of analysis documents these measurements, confirming that the product meets the tolerance levels agreed upon for that specific grade of linen.
Final acceptance of the shipment depends upon the deviation between the delivered width and the target width stated in the purchase order.
