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.
Treats a braid as the mechanism it is: from a starting and finishing braid angle it returns the extension, the diameter it necks down to, the change in enclosed volume, the geometric limit of extension available, and how far the construction sits from the 54.74 degree angle at which a braided tube is neutral under internal pressure.
Calculator
Turns a published bobbin volume into the run a braider actually gets: yarn mass and length per bobbin, how fast each carrier draws it at the braid angle, the minutes and metres before the creel is empty, and the effective output once the change time is charged against every cycle.
Calculator
Turns guide bar runner lengths and yarn counts into fabric weight on a tricot or raschel machine: computes needles in the bed, yarn fed per rack, the weight each bar contributes, the resulting GSM, and the machine output in metres and kilograms per hour at a stated speed.
Calculator
Derives the stock flow a basis weight and wire speed demand, the jet velocity the slice delivers and whether it drags or rushes the wire, then computes the Kerekes crowding number and the consistency that would bring it back to a target.
Calculator
Computes wound length and weight from roll geometry and caliper, counts the splices a given parent-roll interval forces into it, and reports the web those splices waste, the downtime they cost and the availability lost on the converting line.
Calculator
Derives repeat size, shafts for a straight draft, float lengths and intersections from a weave notation, then applies the Ashenhurst rule to give the yarn diameter, the maximum sett the structure supports and how much of it the actual sett uses.
Calculator
Derives filament velocity and diameter from throughput per hole and target denier, compares them with extrusion velocity to give the draw-down ratio, and computes the slip velocity and aerodynamic drag the aspirator air actually delivers.
Calculator
Works out warp throughput from count, ends and speed, derives the size box concentration that an add-on and wet pick-up together demand, and returns the cooked stock and dilution water the box consumes per hour along with its turnover time.
Calculator
Splits a fixed SMS basis weight between spunbond and meltblown, returns the hydrostatic head and tensile strength each split delivers along with the material cost, and solves for the meltblown grams a target barrier actually needs and what that leaves for strength.
Calculator
Applies Archard sliding wear to the needle butt against the cam track, converting machine geometry and speed into sliding distance per hour, wear depth, contact pressure and the running hours before the butt reaches its wear limit.
