How we develop new textures with brands
Most of our development work starts from a brand’s brief, not from a lab. A typical project runs in four steps:
R&D team: 6 dedicated R&D and QC engineers (pattern tooling, substrate testing & packaging dielines). Development equipment: precision GSM analytical balances, digital tensile testers, caliper gauges, 365 nm UV inspection lamps and ultrasonic sample sealers.
