From warp preparation to loom tuning. Explains sheds, beat-up, take-up, and common faults. Includes reed and dent calculations, pick density planning, and productivity improvement with data. 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.
Industrial Weaving & Tire Cord Engineering
Calculates the 45-degree bias modulus of a woven sailcloth from its warp, fill and shear properties, the diagonal strain and elongation under load, and how much of the bias compliance the shear modulus is responsible for.
Calculator
Industrial Weaving & Tire Cord Engineering
Profiles a rapier insertion stroke: available insertion time, peak tape speed, the acceleration the head reaches on a trapezoidal profile, the g-force it represents and the inertial tension spike it puts into the weft.
Calculator
Industrial Weaving & Tire Cord Engineering
Converts torsion bar geometry and twist angle into picking torque, stored elastic energy, the projectile velocity it produces after transfer losses, and the peak shear stress the bar carries on every pick.
Calculator
Advanced Sizing, Slashing & Preparation
Models how warping creel tension builds from package to beam: capstan friction through the guides, drag along the creel length, the tension the furthest end arrives at and the spread against the nearest position.
Calculator
Industrial Weaving & Tire Cord Engineering
Checks whether a loom can beat heavy duck: peak sley acceleration and inertial force at the running speed, the total beat-up load per metre of reed width including fabric resistance, and how much of the machine rating that consumes.
Calculator
Advanced Sizing, Slashing & Preparation
Converts a shop-floor refractometer reading into size liquor solids: temperature-corrected Brix, solids percentage through a size-specific conversion factor, grams of solids per litre, and the error an uncorrected reading would carry.
Calculator
Industrial Weaving & Tire Cord Engineering
Fits an exponential permeability decay to a calendering trial and extrapolates it: permeability achieved at a working line load, the load a target permeability demands, and the total nip force that represents across the fabric width.
Calculator
Warping & Sizing
Estimates direct warping output in metres per hour, the run time to fill a beam of a given length, the yarn weight that beam will carry and the number of beams a shift can deliver.
Calculator
Warping & Sizing
Calculates the exact kilograms of warp yarn to indent for a given set, from ends, warp length and yarn count, with separate allowances for weaving crimp and preparation waste so the order covers loom-state reality.
Calculator
Narrow Fabrics, Tapes & 3D Weaving
Builds terry towel areal weight from its three yarn streams — pile warp at the working pile ratio, ground warp and weft, each with its own crimp — and reports how much of the finished GSM the pile is actually paying for.
