ADF Knitting

All-direction-feeder machines give each yarn carrier its own motor and a free path to the needle, so complex jacquards and multi-yarn structures knit cleanly at speed.

01Electric motorsEach yarn feeder has its own dedicated motor and moves independently.
02Open, split carriageBuilt with an open space inside, so feeders glide freely without interference.
03Horizontal and verticalFeeders move left and right and can drop down or lift up out of the way.
04Direct and constantA direct path from yarn cone to needle minimises tension and friction.

Hydro Washing

Industrial washing with recirculating showering systems sprays recycled, filtered water directly onto tumbling sweaters. The concentrated, low-volume discharge is faster and cheaper to treat in the effluent plant.

Water metric	Hydro technology	Manual hand washing
Average water usage	7 to 10 litres per kg of sweaters	25 to 30 litres per kg
Water saving	Up to 70% of total factory intake	0%, the baseline
Liquor ratio	1:6 to 1:10, highly concentrated, controlled moisture	1:25 or higher, standing water in tubs
Rinsing method	Recirculating showering of recycled, filtered water	Flood rinsing, tubs filled and drained by hand
Effluent treatment load	Low volume, faster and cheaper filtration	Large volumes of diluted, chemical-heavy wastewater

Technology Onboard

Two finishing upgrades are scheduled for the next year, each closing a loop that used to waste steam or water.

Sept 2026Upgraded iron section with G-Trap technology. 100% dry steam: condensate is separated and expelled automatically, so there is no water spitting or staining. The closed steam loop holds pressure up to 12 kg/cm² for high savings, operators spend all their time shaping sweaters instead of draining, and controlled dry steam relaxes knit boundaries for a soft, voluminous finish.
Jan 2027Recycle steam dryer. Captures and recycles exhaust vapour, cutting steam use by up to 40%. Optimised thermal transfer gives fast, predictable cycle times; smart automation stops heating once the garment reaches 6 to 7% moisture; relaxed steam loops act as a built-in softener, dropping wrinkles and keeping wool ultra-soft, all in a small footprint with minimal running cost.

The Next Unit

Rose Sweaters is adding another production unit on site, operational by June 2027, with a further unit planned to start construction by 2029.

01520 knitting machinesThe latest technology across a mix of machine brands, covering a broad range of gauges for greater product flexibility.
02Up to 500,000 pieces a monthProduction starts at 250,000 pieces a month and builds to 500,000 by the end of 2027.
03LEED PlatinumThe building is constructed to the LEED Platinum green-building standard.
04Solar energyA targeted 500 kW installation producing about 16% of the electricity for both the existing and the new unit.
05Water recyclingWater from the laundry is reused in the toilets, and rainwater is harvested for the toilet system.
06Resilient powerThree-channel backup through CNG, generators and the REB grid keeps production running through national supply disruptions.
