Processing & Finishing

Wet and dry processes that deliver the final hand and look. This section explains practical decision criteria, typical test methods, and failure modes that matter in real production. Readers get checklists, calculation steps, and case examples connecting specifications to cost, reliability, and compliance. Links map core concepts to upstream inputs and downstream processes so choices remain consistent across sourcing, manufacturing, and end-use performance. Each article includes definitions, diagrams where helpful, and plain-language notes to help newcomers ramp quickly while giving experienced professionals the depth needed to troubleshoot and optimize. Standards references are cited with context, and whenever trade-offs exist, we make them explicit so you can defend decisions. The coverage also includes metrics, data tables, and example calculations so results are reproducible. Where regulations apply, we highlight jurisdiction, scope, and verification pathways. Tools and templates are provided to speed up daily work without sacrificing rigor.

Product Engineering, Specifications & Feasibility

Fabric Hand & Performance Specification Matrix

Maps subjective hand onto measurable properties: deviation from target for bending rigidity, compression, drape, stretch and friction, the weighted total deviation, a composite hand index and the single property furthest from target.

Grab vs Strip Tensile Conversion Calculator

Converts a strip tensile result into the grab equivalent by modelling fabric assistance from the unclamped width, and reports how much of the grab reading that assistance is actually contributing.
