Production line and factory setup overview
A medium-industrial wet-processing plant converting released greige knitted or woven fabric into dyed and dimensionally controlled fabric through batch preparation, scouring or bleaching, jet or selected open-width dyeing, washing, dewatering, opening, padding, stenter drying and heat setting, optional compacting, final inspection, laboratory release and roll packing. It requires substantial steam, water, heat recovery and wastewater treatment.
Recommended lowest-entry line configuration Proceed only after fixing one fabric family, fibre composition, width, GSM, monthly tonnage, shade programme and buyer finishing standard. A modest integrated basis includes one 100-250 kg low-liquor jet dye machine, preparation and dosing tanks, hydro-extractor or slitter opener, compact six-chamber stenter, inspection/rolling, laboratory, boiler, water treatment and complete effluent plant. Used wet equipment needs pressure, corrosion and control-system inspection.
Production process and implementation sequence
- Greige receiving and batch formation
- Scouring or bleaching
- Jet or selected open-width dyeing
- Washing and neutralisation
- Dewatering and fabric opening
- Padding and stenter drying or heat setting
- Optional compacting or calendaring
- Inspection, laboratory release and roll packing
Products, capacity and market fit
- Domestic fabric finishing can support garment, uniform and home-textile manufacturers.
- A controlled dyehouse reduces dependence on imported finished shades and widths.
- One fabric family lowers recipe, handling and finishing complexity.
- Environmental compliance and repeat shade are prerequisites, not optional extras.
- Dyed cotton or cotton-blend fabric - One fabric family with buyer-defined width, GSM, shade, fastness, skew and shrinkage - Garment, uniform and home-textile factories
- Synthetic knit expansion - Separate high-temperature recipe and heat-setting programme - Sportswear and technical buyers after trials
Core production machinery and line specifications

Raw materials, utilities and factory requirements
- Released greige fabric by fibre, construction, width, GSM and lot
- Buyer-approved dyes, salt/alkali or acid, auxiliaries and finishes with safety data
- Process water, steam/fuel and laboratory standards
- Paper tubes, roll wrap, labels, pallets and machine consumables
- Stable three-phase electricity with transformer, power-quality and motor-starting study
- Central dust or lint extraction with fire-safe collection and housekeeping
- Controlled temperature and humidity suited to the confirmed fibre, yarn or fabric
- Dry covered raw-material and finished-product storage with lot traceability
- Compressed air, process water, steam and wastewater treatment where the selected process requires them
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
