ELITEX details the core technologies behind its blockout fabrics

ELITEX (Dezhou) says its blockout fabrics combine dense weaving, PVC-free coating, UV protection and flame-retardant finishing to deliver high opacity and durability. The company also points to global certifications, a 5-year warranty and partnerships with major window-covering brands.

Why it matters: - Window-covering buyers need fabrics that block light, hold shape, and meet fire-safety requirements without losing performance over time. - ELITEX is positioning its blockout line for residential, commercial, and industrial projects that demand opacity, durability, and indoor safety compliance. - The company’s technical claims are aimed at procurement teams and R&D groups evaluating high-spec blackout materials.

What happened: - ELITEX (DEZHOU) Co., Ltd., founded in 2003 in Shandong, China, outlined four core technologies behind its high-performance blockout fabrics. - The company highlighted high-density double-layer weaving, nano-scale opaque coating, UV/weather-resistant treatment, and flame-retardant finishing. - ELITEX also listed product use cases including roller blinds, vertical blinds, horizontal blinds, roman blinds, and sunscreen fabrics.

The details: - ELITEX uses 100% polyester yarns in a high-density double-layer weave. - The inner layer uses 180–220 threads per inch to mechanically block light before coating is applied. - The base fabric is designed for 99.5% minimum opacity with zero pinholes, verified under ISO 105-B02-2014. - Shrinkage is listed at less than 0.5% after washing, based on ISO 6330. - Fabric weight ranges from 200–450 g/m². - Standard widths are 250 cm, 280 cm, and 300 cm. - The coating process uses a proprietary aqueous acrylic, PVC-free formulation. - ELITEX applies the coating with knife-coating and paste-coating lines. - The multi-layer coating typically uses 2–3 passes. - The coating is said to deliver more than 99.9% light blocking, measured by spectrophotometer. - The finish is matte and designed to reduce glare in roller blinds. - For special orders, ELITEX offers metallic-backed blockout fabrics that reflect up to 85% of infrared radiation. - The UV stabilization package includes nano-titanium dioxide and UV absorbers. - Color fastness is listed at Grade 6–7 under ISO 105-B02-2014 Xenon Arc Lamp testing. - After 1,500 hours of accelerated weathering under ISO 4892-2, the fabric retains 95% tensile strength. - Water repellency is rated ISO 5 on the spray test. - ELITEX says its blockout fabrics come in non-FR and flame-retardant versions. - Flame-retardant chemistry is integrated during coating, rather than applied only as a topical finish. - Certifications listed include German B1, California Title 19, NFPA 701-2015 Method 1, EN 13773:2003 Class 1, BS5867-2 Type B, China B1, AS1530-2, and AS1530-3. - For higher-spec projects, ELITEX also cites GREENGUARD Gold Certified, GREENGUARD Certified, OEKO-TEX Standard 100, and Cradle-to-Cradle environmental standards. - ELITEX gives the blockout fabrics a 5-year warranty against coating delamination, fiber degradation, and color change.

Between the lines: - The technical detail suggests ELITEX is competing on measurable performance rather than generic blackout claims. - The combination of opacity, flame ratings, and environmental certifications is tailored to commercial buyers that must balance aesthetics, compliance, and indoor air quality. - Naming major brands such as Hunter Douglas, Springs Window Fashions, Mermet, Coulisse, Bandalux, Uniline, Louver-Lite, and SunSetter signals an attempt to reinforce supply-chain credibility.

What's next: - ELITEX is likely to keep marketing the fabrics to buyers in commercial buildings, hospitality, healthcare, and other controlled-light environments. - The company’s published specs, certifications, and warranty terms give purchasing teams a checklist for comparing the material against competing blockout products. - More information is available on the company’s website: the company’s website.
