Worsted mill · Piece-dyed route: two workshops on one map
Woven greige is dyed in the piece: inspection and mending → wet finishing → Kroy pre-treatment (optional) → piece dyeing → dry finishing.

Where the route branches
The decision points on the map above, written out — each branch and where it leads.
① Crabbing position / Choose one of two
- Mainstream: scour before crabbing / (clean first · so stains are not set in) → ② Fabric type
- Option: crab before scouring / (set first to relieve weaving stress / sharp patterns, good elasticity · distortion-prone types) → Crabbing method / Choose one of two
② Fabric type
- Clear-finish types (mainstream · gabardine/serge) / scouring only · no milling → ④ Scouring form
- Face-finish types (flannel) / add light milling → ③ Scouring and milling set-up / Choose one of three
Crabbing method / Choose one of two
- Batch → Batch crabbing WPF-ZN / One bath, back and forth · head and tail set alike
- Continuous → Continuous crabbing and drying line WPF-LXZH / Continuous crabbing section
④ Scouring form
- Rope form → Rope scouring WPF-XN / Removes weaving lubricants · size · stains
- Open-width → Open-width washing WPF-JXPX / Runs open-width without creasing / (no untwisting or open-width spreading needed)
③ Scouring and milling set-up / Choose one of three
- Separate: mill, then scour → Milling WPF-1S / Moist heat + mechanical action · lightly felted, fuller face
- Combined: scour and mill in one machine → Combined scouring and milling WPF-4XS / Scouring and milling in one machine · multiple parallel channels
- Mill first → open-width spreading → open-width washing → Milling WPF-1S / Moist heat + mechanical action · lightly felted, fuller face
Crabbing method / Choose one of two
- Batch → Batch crabbing WPF-ZN / One bath, back and forth · head and tail set alike
- Continuous → Continuous crabbing and drying line WPF-LXZH / Continuous crabbing section
Dyeing stage (unique to this route) / Pre-treatment needed for machine-washable / deep shades / printing?
- Yes → Kroy fabric soft-lustre line / Fabric-level chlorination shrink-resist pre-treatment / Descale first → dye afterwards (descaling after dyeing strips the colour) / Pre-owned available · enquire for details
- Conventional → Piece dyeing / bleaching
Drying method / Choose one of two
- Conventional → Drying
- Roller cylinder → Continuous crabbing and drying line WPF-LXZH / Continuous drying section (roller dryer)
Fabric type / (as in ②)
- Face-finish types (after milling) → Raising (raises fibres to form the pile) / Pre-owned available · enquire for details
- Clear-finish types (mainstream) → Shearing (levels the surface) / Refurbished / pre-owned available · enquire for details
Steaming-shrinking method: choose one of two / (determines weft straightening position)
- Pin-chain: selvedge-held conveying / weft straightening before entry → Weft straightening WPF-ZW · pin-wheel type / Corrects weft skew · prevents leg twist after garment washing
- Belt-type: tension-free conveying / weft straightening after shrinking → Belt-type steaming-shrinking WPF-WDYS / Removes residual shrinkage
Decatizing method / Choose one of four
- Batch → Batch decatizing WPF-JXZN-MAX / Even steam · set on one drum
- Continuous → Continuous decatizing WPF-LXZN / Continuous decatizing · balanced in three directions
- Continuous pressure → Continuous pressure decatizing WPF-LXZN-P / Pressurised continuous steam · autoclave-grade set
- Autoclave → Autoclave decatizing machine / Pre-owned available · enquire for details
Handle preference
- Lofty, soft handle required → Handle improvement (optional) / Air-flow softening / Pre-owned available · enquire for details
- Conventional → Final inspection · rolling
