Covers fabric constructions from woven and knitted to nonwovens and composites. Details GSM, cover factor, drape, air permeability, pilling resistance, and handle. Includes test methods and how structure drives performance. 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.
Relates basis weight, fibre diameter and face velocity to penetration, filtration efficiency and pressure drop, returns the quality factor that compares media independently of weight, and shows what reaching a target efficiency costs in grams and in pascals.
Calculator
Converts die geometry and throughput per hole into polymer output, sets it against the process air mass flow to give the air-to-polymer ratio that governs attenuation, and returns the fibre diameter, web basis weight and blower duty that follow.
Calculator
Converts leg length CV into the probability that two socks taken at random will pair within tolerance, then contrasts it with the yield a sorted bin system delivers, and reports the singles and their cost per shift.
Calculator
Solves the areal weight mass balance for the warp and weft counts implied by a measured GSM, sett and crimp, then reports the weight each direction contributes, the tex equivalents and the resulting cover factors.
Calculator
Balances card web against batt output to give the batt basis weight and layer count, then derives carriage traverse time, strokes per minute, the advance between strokes and the lay angle that sets cross-direction orientation.
Calculator
Works a dry binder add-on backwards through application efficiency and emulsion solids to the wet spray required per side, and reports the water the oven has to remove, the finished basis weight and the binder lost to overspray every hour.
Calculator
Works out the loop length a transfer actually demands from needle pitch and the cylinder-dial gap, distributes the shortfall across the loops that rob to supply it, and reports the resulting yarn strain, the tightest setting that will still transfer, and the speed the transfer courses cost.
Calculator
Solves for the loop length that delivers a target finished fabric weight at the finished stitch density, then works back through length and width shrinkage to give the greige weight and density the knitting floor should expect to measure.
Calculator
Converts an order in kilograms into machine hours, finds the smallest machine count that meets the due date once each machine’s own changeover is deducted, and reports completion, slack and how much of the committed time is changeover rather than knitting.
Calculator
Derives production in kilograms per hour from the machine’s own knitting geometry, adds drive, auxiliary and compressed air load, and reports specific energy in kWh per kilogram with the cost, the annual consumption and the carbon behind it.
