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.
Warping & Sizing
Measures warp elongation through a sizing machine zone by zone from roller surface speeds, giving creel-to-beam total stretch and the breaking elongation left in the yarn when it reaches the loom.
Calculator
Warping & Sizing
Converts the moisture load on a sizing machine into an hourly steam demand and running cost, using the latent heat of vaporisation, the usable enthalpy of the supply steam and the thermal efficiency of the cylinder train.
Calculator
Warping & Sizing
Prices a size box recipe by converting starch, PVA and lubricant concentrations into kilograms per batch, then reporting total batch cost, cost per litre of liquor and cost per kilogram of size solids.
Calculator
Warping & Sizing
Determines the dry size add-on carried by a sized warp from before and after oven-dry weights, compares it against the target pick-up, and scales the result into kilograms of size solids for the full warp.
Calculator
Warping & Sizing
Works out how many sections a sectional or pattern warp needs, the ends carried by each band, the exact band width on the drum and the resulting ends per centimetre, so striped and yarn-dyed patterns repeat cleanly.
Calculator
Weaving & Fabric Construction
Converts a target cloth width, end count and weft crimp into the reed width and reed count required in the loom, along with total dents and the ends per inch in reed against the finished cloth.
Calculator
Narrow Fabrics, Tapes & 3D Weaving
Calculates the fibre volume fraction of a 3D woven preform from areal weight, thickness and fibre density, splits the areal weight into Z-axis and in-plane reinforcement, and returns the resin volume fraction and cured composite density.
Calculator
Narrow Fabrics, Tapes & 3D Weaving
Converts needle loom pick rate and pick density into tape speed, metres per tape and total loom output per shift, with woven mass and total picks inserted, for high-speed narrow fabric weaving.
Calculator
Weaving & Fabric Construction
Applies Ashenhurst’s rule to predict the theoretical maximum ends or picks per inch a weave can carry at a given yarn count, and shows how much of that jammed limit an actual sett is using.
Calculator
Weaving & Fabric Construction
Converts loom speed, picks per inch and efficiency into woven fabric output in metres and square metres per hour and per shift, and reports the effective pick insertion rate a loom actually achieves.
