Web formation, bonding methods, basis weight control, filtration, hygiene, and geotextile applications. 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. The coverage also includes metrics, data tables, and example calculations so results are reproducible. Where regulations apply, we highlight jurisdiction, scope, and verification pathways. Tools and templates are provided to speed up daily work without sacrificing rigor.
Nonwovens & Technical Textiles
Checks a filtration geotextile against both governing criteria: the retention ratio of apparent opening size to soil D85, and the permeability ratio against the soil, with permittivity and the flow rate the fabric will pass at the design head.
Calculator
Filtration, Separation & Gas Dynamics
Predicts electret filter ageing: humidity-adjusted charge decay time constant, charge remaining after storage, filtration efficiency now against as-manufactured, penetration and the storage time at which efficiency falls below a required threshold.
Calculator
Filtration, Separation & Gas Dynamics
Models water removal from fuel through a nonwoven coalescer: separation efficiency and penetration through the bed depth, outlet water concentration, water removed, the bed depth a target outlet requires and droplet residence time.
Calculator
Nonwovens & Technical Textiles
Calculates calender nip dwell time, nip pressure from line load, total nip force and the thermal diffusion depth reached in the dwell, against the melting threshold of a bicomponent sheath polymer.
Calculator
Medical, Hygiene & Barrier Textiles
Converts applied bandage tension and layer count into sub-bandage pressure by Laplace’s law, with the shortfall against a target compression class and the number of layers that target actually requires.
Calculator
Nonwovens & Technical Textiles
Estimates the V50 limit velocity of a multi-ply aramid pack from ply count, fabric areal weight and specific energy absorption, and works backwards to the plies needed for a target V50, with pack areal density and panel mass.
Calculator
Filtration, Separation & Gas Dynamics
Models dust collector resistance between cleaning pulses: media and cake pressure drop separately, areal dust loading, total drop at the current point in the cycle, time until the pulse-jet trigger point and the fan power the resistance costs.
