Woven Fabric Weight Tolerances and Linear Metre Yield Calculations
Reconcile woven fabric purchases by calculating linear yield from conditioned mass and usable cuttable width under ISO 3801 and ISO 139 parameters.
Resin Pick Up
Resin Retention
Industrial process calculations measure the percentage of synthetic resin absorbed by a fabric during the impregnation and squeezing stages. Finishing mills track resin pick up to control the hand feel, wrinkle resistance, and durability of the finished textile. This metric represents the ratio of dry resin weight to the original dry weight of the untreated fabric.
It applies to chemical finishing of cellulosic fibres, but is not used for physical coating processes.
Absorption Control
The fabric is passed through a liquid resin bath and then squeezed between heavy rollers to remove excess liquid. Adjusting the roller pressure changes the wet pick up, which in turn determines the final dry resin content. The fabric is then dried and cured in a tenter oven to polymerize the resin.
This locks the chemical into the fibre structure.
Performance Tradeoff
Higher resin levels improve the fabric’s crease recovery but can lead to a severe reduction in tensile and tear strength. Cellulose fibres become brittle when over-treated with cross-linking resins. Mills must carefully balance the chemical concentration to achieve wrinkle resistance without compromising fabric durability.
This requires constant testing.
Quality Auditing
Inspectors measure the resin content of finished rolls to ensure consistency across the entire production batch. If the resin level is too low, the garments will wrinkle easily after washing. If it is too high, the fabric will feel stiff and scratchy.
Regular audits prevent these quality failures.
