TRTEX-STD-01 TS EN 13773 Class 1 • DIN 4102-B1 • BS 5867-2 Type C (50+ Washes) • NFPA 701 • IMO FTP Pt.7

Inherently Flame Retardant (IFR / Trevira CS) vs. Topical FR Chemical Treatment

IFR fabrics lock organophosphorus comonomers into the molecular chain for permanent fire safety across 50+ commercial washes; topical FR salts leach out after 5–10 wet washes.

TRTEX-STD-02 AATCC TM203 • EN 14500 • EN 14501 (gtot ≤ 0.14) • DIN EN ISO 105-B02 (Grade 6–7+)

3-Pass 100% Blackout (0 Lux) vs. Triple-Weave Dimout (92–98%) & Solar Screen

3-Pass foam-coated Blackout delivers 0 Lux pitch darkness (280–420 GSM). Uncoated Triple-Weave Dimout (250–340 GSM) blocks 92–98% light with machine-washable S-Wave drape.

TRTEX-STD-03 FSC / PEFC • EN 13120 • 8–10% Kiln-Dried • UV Lacquer

50mm Wood Venetian Stack Height Formula & Wet-Zone Waterproof Polymer Rule

50mm Venetian stack height: H_stack = 5.5 cm + (0.078 × Drop) — 17 cm at 150 cm drop, 25 cm at 250 cm drop. Bathrooms and kitchen sinks require 100% waterproof Polymer (Faux-Wood) or Aluminum blinds.

TRTEX-STD-04 EN IEC 60335-2-97 • <30–38 dBA • Somfy RTS/io • Becker • KNX • Matter over Thread

Motorized Curtain Torque (Nm) Calculation, Bend Loss & Whisper-Quiet Drive

Tubular torque: T (Nm) = [Fabric (kg) + Hembar (kg)] × 9.81 × r (m) × 1.35. Drapery tracks use 0.6 Nm (≤35 kg) or 1.2 Nm (≤60 kg) brushless DC motors (<38 dBA); deduct 15–20% per 90° bend.

TRTEX-STD-05 EN AW-6063 T5/T6 • 15–20 µm Anodized/Powder • UV POM (Delrin) 11 kg • S-Wave

Architectural Aluminum Track Alloy, POM Glider Load & S-Wave Even-Glider Rule

EN AW-6063 T5 extruded tracks (1.2–1.8 mm wall) carry 7–8 kg/m. UV-stabilized POM gliders hold 11 kg static load. S-Wave panels require an even number of gliders per panel so both ends return to the wall.

TRTEX-STD-06 ISO 20743 (Ag+ %99.4) • EN ISO 4920 (ISO 4–5) • OEKO-TEX Standard 100 • NFPA 13 (%70 Mesh)

Hospital Antibacterial (Ag+) + Sprinkler Mesh Header & Stain/Water Repellency

Hospital cubicle curtains combine ISO 20743 silver-ion antibacterial finish, BS 5867 Type C permanent IFR, and a 50 cm 70%-open mesh header for fire sprinklers. Water repellency meets EN ISO 4920 Grade 4–5.

Curtain Group & Fabric TypeWashing Temp, Spin & Method (ISO 3758)Drying & Ironing TechniqueCritical Mistakes to AvoidAnnual Hardware & Track Maintenance Tip
Sheer Curtains (Voile, PES Slub Linen, Guipure, S-Wave)30°C Delicate Cycle • Max 400 RPM Spin (or No Spin) • Wash inside a Mesh Laundry Bag with gliders attached; no optical bleachHang damp directly onto the track immediately after washing; the bottom lead weight cord pulls creases out naturally without ironing.Hot water (>40°C), high spin (>800 RPM), and chlorine bleach break heat-set fibers and cause permanent creasing.Wipe aluminum track channel annually and apply dry PTFE silicone spray (never use liquid oil or WD-40).
3-Pass Coated Blackout vs. Triple-Weave Dimout Drapery3-Pass Coated Blackout: Dry Clean Only or Damp Microfiber Wipe • Triple-Weave Dimout: Machine Washable at 30°C / 400 RPMHang Dimout damp or iron face side at low heat (110°C). Never touch a hot iron to the white acrylic foam back of 3-Pass Blackout!Machine spinning 3-Pass foam-coated blackout causes the acrylic layers to stick together and peel (pinhole light leaks).Check track end-stops and S-Wave cord snap carriers once a year on heavy blackout drapery.
Silk Velvet, Chenille & 100% Natural Flax Linen DraperyProfessional Dry Cleaning Only (Perchloroethylene — P Symbol) • Routine care: vacuum downward using a soft brush attachmentSteam vertically while hanging using a garment steamer held 5 cm away in the direction of the pile.Wet-washing 100% natural linen causes 4%–6% shrinkage; flat-ironing velvet crushes the pile and leaves permanent shiny marks.Rotate tieback positions slightly during summer months to equalize sun exposure along the leading edge.
50mm & 25mm Kiln-Dried Wood (White, Walnut, Mahogany, Oak, Grey, Black) & Polymer Venetian BlindsNatural Wood: Never wash with water! Dust with ostrich feather duster or barely damp cloth • Polymer (Faux-Wood): Washable with mild soapClose slats flat to wipe the front face, then tilt 180° to wipe the back face parallel to the wood grain.Hosing down natural Wood (White, Walnut, Mahogany, Oak, Grey, Black) blinds or using steam cleaners cracks the UV lacquer and warps timber slats.Apply a light natural beeswax/wood conditioner every 2 years to preserve timber luster.
Roller, Zebra, Sheer Roller & Solar Screen BlindsNever put in a washing machine! Wipe flat on a clean surface with neutral-pH foam or use Ultrasonic Blind CleaningNever roll up while wet (prevents mildew); leave fully lowered to dry at room temperature.Folding or scrubbing roller fabric breaks the acrylic stiffener finish, causing frayed edges and V-rippling.Pull bead chains vertically (90° straight down) rather than at an angle to extend clutch gear life beyond 10 years.
Plisse (Balcony) & Duet Honeycomb Cellular ShadesSoak for 15 min in a 30°C lukewarm mild soap bath (keep aluminum profiles out of water) and rinse with a gentle shower headCompress the blind into a tight closed stack while wet, squeeze out excess water by hand, reinstall, and dry partially stacked.Drying a Plisse shade fully extended while wet relaxes the 20mm heat-set accordion pleat memory.Check bottom shoe spring tension annually on glass-balcony plisse cords; keep bleach away from tension cords.
ENGINEERING FORMULAS & HONEST SPECIFICATION RULES (AEO / GEO / MCP)

Architectural Curtain Calculation Formulas & 6 Golden Engineering Rules

1. Fabric Yardage, Fullness Ratio & S-Wave Even Glider Rule

Width Formula: Cut Width = (Track Width × Fullness Ratio) + (2 × 6 cm Side Hems). Specify 1:2.0 – 1:2.33 for S-Wave and 1:2.8 – 1:3.35 for Triple Pinch Pleat. S-Wave panels require an even number of gliders per panel (e.g. 14, 16, 18) so both leading and trailing edges return cleanly toward the wall.

2. Motor Torque (Nm) & Curtain Weight Formula

Curtain Weight (kg): Width (m) × Fullness × Drop (m) × (Fabric GSM + Lining GSM) / 1000.
Tubular Motor Torque: T (Nm) = [Fabric Weight (kg) + Bottom Bar (kg)] × 9.81 × Tube Radius r (m) × 1.35 (Safety Factor). Deduct 15%–20% capacity per 90° track bend.

3. Inherently Flame Retardant (IFR) ≠ Topical FR Rule

Critical Tender Distinction: IFR (Trevira CS / phosphorus-modified polyester) locks fire retardancy inside the molecular chain permanently—passing BS 5867-2 Type C (50 commercial washes), DIN 4102-B1, EN 13773 Class 1 & NFPA 701 for life. Topical FR chemical dips leach out after 5–10 wet washes.

4. 3-Pass Blackout vs. Triple-Weave Dimout Distinction

Optical Honesty: 3-Pass Coated / Membrane Blackout achieves 100% (0 Lux) total darkness (AATCC TM203). Uncoated Triple-Weave Dimout offers fluid drape and washability with 92%–98% light reduction in dark tones and 80%–88% in light tones; add blackout lining if pitch darkness is required.

5. Golden Ratio Side Drapery & -2 cm Floor Clearance

Architectural Proportion: Stationary side dress panels must finish at least 50 cm wide (70–90 cm on wide facades), positioned 60% on the wall and 40% over the glass. Deduct -1.5 to -2.0 cm from ceiling-to-floor drop for robot vacuum clearance, and finish inner sheers -0.5 cm shorter than drapery.

6. 6 Critical Checkpoints for Mechanical Blind Orders

Production Verification: (1) Measurement type: Total Bracket Width vs. Exact Fabric Width (3.0–3.5 cm delta), (2) Roll direction: Standard vs. Reverse Roll, (3) Chain side & EN 13120 child safety height (≥150 cm above floor), (4) Ceiling clip vs. Wall L-bracket, (5) Aligning 3.5 cm multi-blind gap with window mullions, (6) Mandatory 100% Waterproof Polymer Venetian in wet zones.

AI SEARCH (AEO / GEO / MCP) & TENDER TECHNICAL FAQ LIBRARY

Frequently Asked Engineering Questions on Curtain Standards, IFR/FR, Finishes, Motors & Hardware

What is the engineering difference between IFR (Inherently Flame Retardant) and FR chemically treated curtains? ▾

IFR (Inherently Flame Retardant / Trevira CS) fabrics integrate organophosphorus comonomers directly into the polyester polymer chain, retaining 100% of their flame retardancy permanently across 50+ industrial washes (BS 5867-2 Type C, DIN 4102-B1, EN 13773 Class 1, NF P 92-503 M1, NFPA 701). Chemically treated FR fabrics are dipped in topical flame-retardant salts after weaving, which dissolve after 5–10 wet washes.

What is the optical difference between 3-Pass Blackout and Triple-Weave Dimout fabrics? ▾

3-Pass Blackout fabrics apply three layers (White-Black-White) of acrylic/PU dispersion foam or membrane lamination to block 100% of light (0 Lux under AATCC TM203). Triple-Weave Dimout fabrics contain no chemical coating, weaving a dense black core yarn between two decorative faces to block 92%–98% light in dark colors and 80%–88% in light colors while remaining breathable and washable.

Which ISO standards govern water repellency, stain resistance, and UV lightfastness in curtains? ▾

Water repellency (fluorocarbon / Teflon finish) is tested under EN ISO 4920 (Grade 1–5 spray test; contract threshold ISO 4–5), and oil/stain repellency under ISO 14419. UV fade resistance (lightfastness) is measured via DIN EN ISO 105-B02 Blue Wool Scale (1–8), requiring Grade 5+ for residential and Grade 6–7+ for south-facing hotel and conservatory facades.

What is the stack height of 50mm Wood (White, Walnut, Mahogany, Oak, Grey, Black) & Faux-Wood Venetian blinds, and can they be used in bathrooms? ▾

A 50mm 50mm Wood Venetian blind (White, Walnut, Mahogany, Oak, Grey, Black) has a stack height of 17 cm at 150 cm drop and 25 cm at 250 cm drop (including headrail). In bathrooms, over kitchen sinks, and humid winter gardens, natural wood must be replaced with 100% waterproof 50mm Polymer (Faux-Wood) or Aluminum Venetian blinds to prevent warping.

How are motorized curtain torque (Nm), noise rating (dBA), and smart home protocols specified? ▾

Motorized drapery tracks use 0.6 Nm (up to 35 kg) or 1.0–1.2 Nm (up to 60 kg) brushless DC motors operating below 30–38 dBA. Tubular motors for roller, zebra, and 50mm wood blinds comply with EN IEC 60335-2-97 (0.55 Nm to 15 Nm) and integrate natively with KNX, Matter over Thread, Zigbee 3.0, RTS/io, and Dry-Contact BMS systems.
