PC-STR-220 is a 65/33/2 poly-cotton-spandex twill engineered for uniform trouser programs where mobility and tailored appearance must coexist — hotel front desk, corporate management, airline cabin crew, and stretch work pants for active professional roles.
2% spandex content delivers 20–25% weft stretch and 12–18% warp stretch — enough to eliminate the restriction of traditional rigid twill without compromising the tailored silhouette that professional dress trousers require. The recovery rate of ≥90% after 50 washes ensures the fabric returns to its original shape after repeated wear and laundering — no bagging at the knees, no sagging at the seat.

2% is the industry standard for dress uniform trousers. It provides stretch where needed (bending, sitting, reaching) without distorting the fabric’s structure or compromising the sharp crease that management and front-of-house uniforms require. Higher spandex content is better for activewear but looks and drapes less like a tailored trouser.
Fabric Hand & Appearance
Hand feel: Clean, crisp PC twill hand with a subtle give when stretched. The spandex is not noticeable in the hand — the fabric feels like standard PC twill until you pull it.
Appearance: Standard twill 2/1 appearance. No visible rubber or synthetic shine. The spandex is fully concealed within the core-spun yarn construction.
Drape: Structured with stretch recovery. Holds a trouser crease through a full shift. Does not bag at knees or seat — a critical advantage over non-stretch twill for seated office roles.
Applications
Application
Why PC-STR-220
Hotel front desk & management trousers
Professional crease with mobility for standing, sitting, and moving through the lobby
Corporate office dress pants
All-day comfort for desk-bound roles — stretch eliminates fabric tension when seated
Airline cabin crew trousers
Mobility for cabin service — bending, reaching, walking aisles — with recovery between flights
Stretch work pants (light industrial)
Active roles requiring bending and kneeling — stretch prevents seam stress
Hospitality management uniforms
Tailored appearance for guest-facing roles with unrestricted movement
Convention & event staff trousers
Long standing shifts — stretch reduces fatigue from restricted fabric
Casino floor staff
Professional look with mobility for walking extended floor shifts
Machine wash 60°C, normal cycle — industrial wash compatible
Bleaching
Do not bleach — chlorine degrades spandex elastic recovery
Drying
Tumble dry medium, or hang dry — do not high-heat tumble (heat degrades spandex)
Ironing
Medium iron (150°C) — spandex is heat-sensitive above 180°C
Dry cleaning
Permitted (PCE) — recommended for structured garments
⚠️ Spandex care: High-temperature washing (60°C+) and high-heat drying will accelerate spandex degradation. For maximum stretch recovery lifespan, wash at 40°C and hang dry. At standard industrial laundry (60°C, tumble dry medium), expect ≥90% recovery for 50 cycles — approximately 12–18 months of weekly wear. After 50 washes, recovery gradually declines but the fabric remains functional as a standard twill.
FAQ
Q: Will the spandex lose its stretch over time? A: All spandex degrades with heat, chlorine, and mechanical agitation. PC-STR-220 maintains ≥90% recovery through 50 industrial washes (60°C). After 50 cycles, recovery gradually declines — the fabric will still stretch but may not return to its original shape as completely. Most uniform programs replace trousers at 12–18 month intervals, which falls within the 50-cycle window.
Q: Does this fabric hold a trouser crease despite the stretch? A: Yes. 2% spandex is low enough that the fabric still holds a knife-edge crease when pressed. The polyester content provides heat-set crease retention through multiple washes. This is the standard specification for airline cabin crew trousers worldwide — the crease must hold, and the fabric must stretch.
Q: How does this compare to the linen stretch fabric (LS-5243)? A: PC-STR-220 has higher stretch (20–25% vs. 15–20%), better recovery, and a lower cost. LS-5243 has a premium natural linen appearance and texture but slightly less stretch performance. For corporate and aviation programs where appearance consistency is critical, PC-STR-220 is the standard choice. For resort and premium hospitality where natural fiber aesthetics matter, LS-5243 is preferred.
Q: Is this fabric suitable for women’s fitted trousers? A: Yes — the 20–25% weft stretch is particularly well-suited for women’s slim-fit and skinny-cut trousers where fabric must conform to the body without restricting movement. The recovery ensures the fabric does not bag at the seat or knees after sitting.
Q: What is the most popular specification for aviation cabin crew programs? A: Dark Navy + stretch (no additional finishes) is the most common specification for cabin crew trousers. Navy + stretch + stain-release is the second most common — particularly for carriers that serve meals onboard.
