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.
Calculates the extra path length a leno crossing end travels from crossing amplitude and pick spacing, converts any shortfall in let-off compensation into strain, and reports the resulting crossing end tension against the yarn breaking load.
Calculator
Converts label loom speed and ultra-high pick density into cloth speed, labels per hour and picks per label, then projects defective labels and defect rate from a per-million-picks insertion defect rate.
Calculator
Works out how large a jacquard design repeat can be on a given machine: total ends in the cloth, ends and width per repeat, hook utilisation and spare hooks, plus the maximum repeat height allowed by pattern memory at the working pick density.
Calculator
Calculates the lifting load on a dobby shaft or jacquard harness from ends per shaft, warp tension, shed angle and heald frame mass, and compares it against the rated shaft capacity to prevent machine overload.
Calculator
Calculates the grams per square metre of a woven fabric and the warp and weft yarn required per 100 metres, from ends per inch, picks per inch, yarn counts, crimp and process wastage.
Calculator
Separates the width lost between the reed and the loom-state cloth from the width lost in wet processing, so a finished width target can be traced back to the correct reed width.
Calculator
Checks whether the drying cylinders on a sizing machine can carry the moisture load, by converting ends, speed and yarn count into dry warp throughput and the kilograms of water that must be evaporated each hour.
Calculator
Turns a three-length stretch test on elastic tape into elongation, permanent set and elastic recovery, and converts the load at extension into engineering modulus and force per centimetre of width for waistband and bandage specifications.
Calculator
Calculates warp and weft crimp and take-up percentages from straightened yarn lengths measured against the fabric sample, the figures that drive yarn consumption, fabric weight and loom take-up settings.
Calculator
Splits a total warp end count across the available creel pegs, returning the number of warper beams required, an even ends-per-beam distribution, creel utilisation and the spare pegs left over.
