Sarelli Interiors Textiles produces light curtains using specialized rapier looms, electronic Jacquard looms, and air-jet weaving machines. Industrial textile machines handle ultrafine yarns ranging from 15 to 40 denier to create sheer fabrics weighing between 30 and 80 grams per square meter.
Rapier looms for plain sheer fabrics
Rapier looms weave plain light curtains by carrying the weft yarn across the warp threads using mechanical gripper heads. Sarelli uses rapier machines operating at 400 to 600 picks per minute to manufacture delicate linen and silk voiles without breaking the fragile natural fibers.
Rapier looms maintain a warp tension of exactly 12 to 15 centinewtons per yarn end. Precise tension control allows Sarelli textile engineers to weave 50-gram-per-square-meter linen sheers with a maximum defect rate of 0.2 percent per 100 linear meters. Customers can view examples of these precision-woven textiles in the Production Methods documentation.
Electronic Jacquard looms for patterned light curtains
Electronic Jacquard looms produce patterned light curtains by individually lifting up to 12,000 separate warp threads per weaving cycle. Sarelli employs Jacquard technology to weave complex floral and geometric motifs into sheer fabrics while maintaining a low overall fabric weight.
A modern electronic Jacquard loom running at 800 picks per minute produces 45 linear meters of patterned organza per eight-hour shift. Sarelli programs Jacquard machines to integrate 20-denier silk warp threads with 30-denier cotton weft threads, creating intricate designs on fabrics that weigh exactly 65 grams per square meter. The Sheer Fabrics Production guidelines detail the specific software calibration required for these complex patterns.
Air-jet looms for high-speed voile production
Air-jet looms manufacture uniform light curtains by propelling the weft yarn across the loom using bursts of compressed air. Textile manufacturers use air-jet machines to weave synthetic and blended sheer fabrics at speeds exceeding 1,000 picks per minute.
Air-jet weaving machines consume between 40 and 60 cubic meters of compressed air per hour at a pressure of 6 bar. Sarelli relies on air-jet technology to produce 300-centimeter-wide polyester voiles weighing 45 grams per square meter, achieving a production output of 120 linear meters per machine daily. The specific fiber blends compatible with air-jet weaving are listed in the Fabrics Composition index.
Finishing equipment for light curtain textiles
Finishing equipment stabilizes light curtains through controlled heat setting and chemical treatments. Sarelli processes freshly woven sheer fabrics through stenter frames operating at 180 degrees Celsius to lock the yarn structure and prevent future shrinkage.
The stenter frame applies a consistent tension of 20 kilograms across the 320-centimeter fabric width for exactly 45 seconds. Thermal stabilization processes ensure that Sarelli light curtains experience less than 1.5 percent dimensional shrinkage after 10 standard washing cycles. The final stabilized textiles join the main Fabrics inventory for distribution.
