Product White Paper: White 100% Polyester Linen-Look Sheer Curtains
I. Fabric Composition & Technical Specifications
Parameter    Specification / Description
Fiber Content    100% Polyester (PET)
Fabric Structure    Linen-look weave; plain/twill base with differential shrinkage process to achieve natural linen-like texture and slub effect
Weight    ≥250 GSM (recommended for optimal drape and privacy)
Width    280cm / 300cm (fixed height, sold by width; suitable for standard residential and hotel ceiling heights)
Setting Process    High-temperature heat setting (≥180°C); pleat retention rate ≥95%; no re-ironing required after washing
II. Performance Specifications
1. Optical Properties
Light Transmittance: 30%-40% (achieving a "light-filtering yet opaque" effect through high-density weaving)

UV Blockage: ≥70% (effectively reduces fading of interior furnishings)

Privacy Level: Exterior visibility obstructed during daytime; meets basic privacy requirements for bedrooms

2. Physical Properties
Parameter    Performance
Wrinkle Resistance    Crease recovery angle ≥250°, superior to natural linen (typically ≤180°)
Shrinkage Rate    ≤1% (warp direction); complies with GB/T 19817-2005 Textiles – Fabrics for Decorative Purposes
Color Fastness    Light fastness ≥ Grade 4 (ISO 105-B02); washing fastness ≥ Grade 4
Snagging / Pilling    Anti-pilling rating ≥ Grade 3-4 (superior to standard sheer fabrics)
3. Environmental & Safety Compliance
Formaldehyde Content: Not detected (complies with GB 18401-2010 National General Safety Technical Code for Textile Products, Category A / direct skin contact standard)

Carcinogenic Aromatic Amine Dyes: Prohibited; complies with OEKO-TEX® Standard 100 Class I or II

Anti-Static Treatment: Optional anti-static finish available to reduce surface resistance and minimize dust attraction

III. Material Science Advantages
1. Molecular Structure Advantages
Polyester (PET) macromolecular chains feature high symmetry and crystallinity, providing:

Low moisture absorption (moisture regain ≤0.4%): exceptional dimensional stability; no deformation under humidity fluctuations

Thermoplasticity: permanent pleats and drape retention through heat setting; excellent recovery after washing

2. Linen-Like Mechanism
Achieved through profiled cross-section spinnerets (cross-shaped, Y-shaped) and alkali reduction treatment:

Dry hand feel and subtle surface fibrillation characteristic of natural linen

Overcomes inherent drawbacks of natural linen such as wrinkling, shrinkage, and low color fastness

IV. Application Suitability
Bedroom Environment Requirements & Product Match Analysis

Maintenance Cost    Low    High (dry cleaning or low-temperature ironing required)    Medium (prone to shrinkage)
VI. Procurement / Selection Recommendations
1. Weight Selection
Primary bedroom sheers: ≥250 GSM recommended to ensure daytime privacy

Living room decorative sheers: 200-220 GSM suitable; prioritize light transmission

2. Setting Process
Heat setting required: Non-heat-set polyester sheers may develop wrinkles or deform after initial washing. Heat-set products maintain drape and pleat integrity throughout their service life.

3. Installation Considerations
Recommended pleat ratio: 1.8-2.0×, combined with pinch pleat or S-hook hardware for optimal drape

Recommended floor clearance: 0.5-1 cm; avoids dust accumulation while maintaining visual continuity

VII. Conclusion
The white 100% polyester linen-look sheer curtain achieves a highly balanced performance across material cost, physical properties, maintenance convenience, and optical privacy protection. Through synthetic fiber engineering, it replicates the aesthetic qualities of natural linen while overcoming the inherent limitations of natural fibers in dimensional stability and durability.

For bedroom window treatment solutions requiring high cost-effectiveness, low maintenance requirements, and long-term visual stability, this product represents one of the most comprehensively optimized options currently available in the market.
