Contractual Weight Tolerance Bands and Yield Risk Allocation in Bulk Fabric Procurement
Contractual weight tolerance bands govern linear yardage yield, moisture regain adjustments, and cutting room markers to protect garment cost margins.
Interlock Knit Weight
Mass Measurement
Fabric mass per unit area in double-knit textiles constructed from two interlocking ribbed structures determines drape, opacity, and thermal insulation. Interlock knit weight quantifies the mass, measured in grams per square meter, of a smooth double-faced knit fabric produced on opposing needle beds. The metric governs fabric selection for activewear and structured jersey apparel, applying specifically to double-knit constructions and stopping when single-jersey or complex jacquard mesh knits are evaluated.
Machine gauge, stitch length, and yarn count directly establish nominal fabric mass during knitting operations.
Structural Density
Interlocking loops lock structure on both sides, creating a thicker cross-section than single jersey. High needle density and short stitch lengths yield dense, heavy fabrics with low extension. Relaxed finishing allows yarn loops to round out, increasing fabric thickness.
Finishing Adjustments
Compacting ranges reduce longitudinal tension, allowing interlock knits to reach target mass targets without excessive width shrinkage. Uncontrolled stenter tension pulls loops flat, causing weight drops below specification. Finishing mills balance width overfeed to maintain stable weight profiles.
Quality Standard
Garment manufacturers verify fabric mass using circular cutter samples tested across fabric roll widths. Discrepancies in interlock weight alter garment drape and seam bulk. Commercial lot specifications define strict mass limits to guarantee uniform garment sizing.
