Blackout Curtain Manufacturer in China

Industry standard: a single blackout curtain panel blocks 95–100% of light. True 100% requires both the right fabric (coated, composite, or physical blackout) and proper installation — ceiling mount or wall-to-wall coverage with overlap or return panels at the edges. Light-blocking percentage on its own is a fabric spec, not a system guarantee.

Industry standard: room darkening fabrics block 70–90% of light, while blackout fabrics block 95–100%. Room darkening is typically achieved through heavyweight fabric alone, while blackout requires either a coating, a composite construction, or yarn-level woven blackout. Dairui produces both categories — confirm your light-blocking requirement with our team during inquiry.

Side leakage is a system issue, not a fabric issue. To eliminate it: (1) use ceiling mount or wall-to-wall installation rather than window-frame mount, (2) specify return panels or overlap at the edges, and (3) consider a track system for ripplefold or S-fold headings, which give continuous coverage with no gap. We can recommend the right system for your project during inquiry.

Both are valid. Coating applies a blackout layer directly to the back of the face fabric — cost-efficient, simpler construction, slightly stiffer handfeel. Lining (composite blackout) bonds two fabrics together with a TPU film or coating between them — softer drape, higher cost, more design flexibility because face and back fabrics can be specified independently. Dairui produces both routes; the right choice depends on your end-use and budget.

Dairui blackout curtains range from 180 gsm (lightweight, drape-focused) to 400 gsm (heavyweight, hospitality and project use). DTC retail typically falls in the 200–260 gsm range. For 100% blackout with soft handfeel, 240 gsm coated polyester or composite linen-look is a common choice. Heavier weights improve thermal insulation and sound dampening but increase shipping volume — confirm your priorities with our team during sample selection.

Standard MOQ for in-stock fabrics is 200 pieces per style and per color. For first-time customers, trial orders from 50 to 100 pieces are available subject to discussion. For custom-woven fabrics, the minimum is 800 to 1,000 meters. Dropshipping orders (1 piece minimum) are available through our dropshipping service line for online retailers and Shopify brands.

Typical bulk production takes around 30 days from deposit confirmation, depending on order volume, customization scope, material readiness and the current production schedule. Sample lead time is usually 3–5 working days for standard samples; special sample types or processes are quoted separately.

Every production batch is inspected by third-party agencies SGS and Intertek before shipment, with an inspection report issued per order covering stitching, dimensions, blackout performance and packaging. Blackout fabrics are also available with OEKO-TEX® Standard 100 certified yarns sourced through our supplier network, for non-toxic and low-VOC requirements. For hospitality and project orders, constructions can meet NFPA 701 (US) and BS 5867 (UK/EU) flame-retardant standards, with test certificates issued per order. Please specify your certification requirements at the inquiry stage so we can source the matching certified base cloth and arrange testing.

Compare construction, required light-blocking result, approved sample and finished-size tolerance — not just a blackout label. Confirm how color, coating or woven black yarn, stitching and bulk controls affect the final panel. For project or private-label orders, also confirm required reports, MOQ, labels, packing and carton marks. Use our curtain manufacturer comparison checklist for the full review.
