Elastic fiber and stretch fabric engineering laboratory

Elastic fiber systems measured through fabric and garment use

Lycra Fiber and Stretch Fabrics with Method-Defined Recovery

Define fiber form, linear density, blend level, placement, fabric construction, GSM, usable width, stretch direction, extension, cycles, recovery interval and conditioning before a trial advances.

Six engineering controls

Stretch performance is a system, not a fiber name

01

Linear Density

Denier or count, filament form and package are stated with units.

02

Blend & Placement

Elastic content and yarn position are tied to the fabric construction.

03

Stretch Direction

Course, wale, warp, weft or multi-direction behavior is named.

04

Recovery Method

Extension level, hold, cycles, conditioning and recovery interval are recorded.

05

Heat & Care

Heat setting, dyeing, laundering and finishing can change behavior.

06

Lot Release

Construction, shade, finish, test scope and lot remain connected.

Fabric test report

Method, specimen, extension, recovery, cycles, conditioning and result.

Content or custody record

Claimed content, entity, product scope, chain and validity.

Regulatory statement

Jurisdiction, requirement, material or article and declaration date.

Put extension, cycles and recovery time in the brief

Submit the garment use, fiber or yarn form, placement, fabric construction, direction, target extension, recovery interval, heat-setting route, method, quantity and destination.
