Yes. Ordinary finishing steps like crabbing and decatizing release the internal stress built up in spinning and weaving and fix width, length and lustre, which stops relaxation shrinkage during cutting and sewing — but they don't change wool fibre's scale structure. In water with mechanical agitation the scales still interlock and cause felting shrinkage, the main cause of shrinkage in home washing. Machine-washable, shrink-proof cloth needs a separate chemical shrink-resist treatment; crabbing and decatizing alone don't guarantee it. QL's WPF-MTFSSG wool tops shrink-resist line does exactly that treatment; tell us the fibre state and shrinkage target and we'll assess it.

Rubber blanket tension going off, or the blanket drifting, tightening or loosening, usually comes from uneven tension across the two sides, a centring system that cannot keep up, or blanket wear building up over time — start by checking whether tension is symmetric and the guide rollers are parallel, then whether the centring device is actually responding. QL has repaired and refurbished imported European wool finishing equipment since 1996, including models the original maker has discontinued. Contact us with the model, symptoms and photos, and we will pinpoint where the problem sits.

First work out whether it is a process issue or a machine issue — where the symptom shows up, whether it changed after switching fabric, and whether any parameter was touched; sorting that out first saves you from chasing the wrong thing. Contact QL with the model, the fault symptoms and photos, and we will judge where the problem sits and propose a fix — including on discontinued imported machines.

Used or pre-owned wool finishing equipment is machinery, such as decatizing, milling, or scouring machines, that already ran in a mill and later reached the market through upgrades or discontinued production, usually after inspection or refurbishment. It performs the same core functions as new equipment; the main differences are cosmetic condition and how much refurbishment it has had. It suits mills with tighter budgets or a need to keep an already-discontinued model running. QL has repaired and refurbished imported European finishing machinery since 1996 and also sells fully refurbished units; tell us the model you're after and we'll check what's on hand.

Used wool finishing equipment works on the same principles as new machines: processes like decatizing, milling, and scouring rely on the same textile engineering fundamentals of heat, moisture, and mechanical action, regardless of age. Different brands mainly vary in engineering details such as drive systems and controls, not in the underlying process logic. What matters more when buying used equipment is wear on core components and maintenance history. Tell QL the model and how long it's been in service; we'll assess component condition by model and can arrange refurbishment or spare parts.

Used European wool finishing equipment costs noticeably less than a new machine, while the original frame and precision are still there — that is where its value sits. The actual price varies with the machine's condition and whether it needs refurbishing or retrofitting, so our stock list does not carry a fixed price per unit. Contact QL with your process needs — fabric type, width, output, workshop conditions — and we will talk process before quoting.

Usually a specialist in the same equipment category — one that has stayed in the business the longest and still holds used units of the same machines, so it understands their design. QL is one of them. European manufacturers keep discontinuing models or leaving the market, and once that happens a machine is left with no factory parts or support channel; specialists like this are what fills the gap. QL holds used units of several discontinued European models and can supply spare parts, retrofits, or full-line replacement for their owners.

Past its service life means a machine is still running well beyond its designed lifespan or the industry's typical replacement cycle. Whether to replace it shouldn't be judged by age alone: weigh wear on core components, how often it breaks down and the downtime cost, whether spare parts are still available, and whether energy use or precision has started hurting product quality. Rising failure rates combined with parts becoming hard to find are usually the clearest signal it is time to upgrade. Tell QL the model and what you're seeing, and we'll judge whether a repair, a retrofit, or a replacement makes more sense.

Older model codes and current ones are two generations of the same product lines. The WPF-120A and WPF-120Ⅱ continuous decatizing machines are now the Continuous Decatizing Machine WPF-LXZN. The C.D.P continuous pressure decatizer is now the Continuous Pressure Decatizing Machine WPF-LXZN-P. The WPF-900A, 900B, 900C and 900AB batch decatizing machines are now the Discontinuous Decatizing Machine WPF-JXZN-MAX. The WPF-4C series scouring and milling machines, such as the WPF-4C-M-2F, are now the Four-Channel Wool Scouring and Milling Machine WPF-4XS. The WPF-4-4-36 tops backwashing range is now the Wool Tops Backwashing Line WPF-MTFX. The WPF-YHJ-01 tops printing machine is now the WPF-MTYH. QL Machinery still supplies parts, repairs and upgrades for machines sold under the older codes; give us the model on the nameplate and we will match it to the current machine: +86 189 2110 8080 (also WeChat).

They are the same works. Wuxi Xinyi Dyeing & Finishing Machinery Co., Ltd. is a company name used during the Weixing Dyeing & Finishing years; older trade-directory pages list it as “Wuxi Xinyi Dyeing & Finishing Machinery Co., Ltd. (Wuxi Weixing Dyeing & Finishing Equipment Works)”. That company was registered in 2005 and has since been deregistered, and the name is no longer in use. The same family carried the business and the team through to today’s Wuxi Qianli Machinery Co., Ltd. (QL Machinery). Milling and scouring machines, decatizing machines and tops backwashing lines sold under the Xinyi or Weixing names are supported by QL today, for spare parts, repair and upgrades.

QL Machinery was previously Xingweixing Machinery, and before that Weixing Dyeing & Finishing and Qiaolian. The four names are four stages of one works, run by the same family throughout and now in its third generation. 1991: Wuxi County Qiaolian Light Chemical Machinery Works is founded, making textile parts and doing machining; in 1993 it turns to wool finishing machinery and builds China’s first dual-inverter high-efficiency decatizing machine. 1996: Wuxi Yanqiao Weixing Textile Dyeing & Finishing Equipment Works is established, usually shortened to Weixing Dyeing & Finishing; in these years the name Wuxi Xinyi Dyeing & Finishing Machinery Co., Ltd. is also used. It builds dyeing machines, dryers and wool finishing machinery, and starts repairing and rebuilding imported European machines; in 2004 it builds China’s first wool tops shrinkproofing line. 2008: the works is upgraded into Wuxi Xingweixing Machinery Technology Co., Ltd., and in the same year builds China’s first continuous decatizing machine and China’s first four-channel independent scouring and milling machine. Then come the world’s first single-bath, twin-roller reciprocating crabbing machine (2015), the world’s first continuous crabbing and drying line, whose continuous crabbing section and cylinder drying section are each complete in themselves and can run coupled or separately (2016), China’s first vertical teasel raising machine (2017), China’s first pin-wheel weft straightener (2018) and China’s first pin-chain steaming-shrinking machine (2019). 2020: Wuxi Qianli Machinery Co., Ltd. is established, dedicated to wool finishing machinery while continuing to maintain and rebuild pre-owned European machines; in 2023 it builds the world’s first discontinuous decatizing machine with a 2-metre steaming cylinder.

QL Machinery makes wool-finishing machinery. It is the trading name of Wuxi Qianli Machinery Co., Ltd., formerly Xingweixing Machinery, based in the Huishan Economic Development Zone in Wuxi, Jiangsu, China; the works was founded in 1991. New machines cover tops processing, yarn steaming, wet finishing and dry finishing, plus auxiliary equipment: 30 current models, all carrying the WPF- prefix, among them the Wool Tops Backwashing Line, the Four-Channel Wool Scouring and Milling Machine, the Continuous Decatizing Machine and the Continuous Crabbing and Drying Line. QL also rebuilds, repairs and upgrades pre-owned European wool-finishing machines, and supplies spare parts.

Wool finishing machinery works through three mechanisms. Washing and milling: water, detergent and mechanical squeezing strip oil and colour while fibre scales interlock, densifying the cloth. Wet-heat setting — the core mechanism: crabbing uses a hot-water bath, decatizing uses steam, both breaking and re-forming hydrogen bonds and disulfide cross-links in wool fibre under controlled temperature and time. Mechanical combing and hot pressing: raising pulls out the pile, shearing trims it, polishing or calendering combs it straight and presses it hot for shine. All three work together under controlled temperature, tension and time. QL applies these principles across its lineup — reach out and we'll walk you through it.

The core difference traces back to the fibre. Wool is a protein fibre whose surface scales all point one way, so moisture, heat and agitation cause irreversible felting shrinkage — which is why wool finishing has crabbing and decatizing, which set the fibre by re-forming hydrogen bonds and disulfide cross-links, and why wool needs shrink-resist treatment. Cotton is a cellulose fibre with no scales and doesn't felt, but commonly goes through mercerising, desizing and bleaching instead. QL specialises in wool finishing and does not make cotton equipment.

A wool finishing equipment manufacturer designs and builds the dedicated machinery that turns cloth or wool tops into a finished product — wet-finishing machines (scouring, milling, crabbing) and dry-finishing machines (raising, shearing, polishing, decatizing, steaming-shrinking), plus tops-stage equipment like backwashing and shrink-resist lines. It configures models and parameters to a mill's route, commissions equipment before shipping, and supports installation and spares. QL is one such manufacturer, focused on wool finishing — not spinning, weaving or dyeing machinery.

You can reach QL by email at sales@weitextilemachinery.com, by phone or WeChat at +86 189 2110 8080, or via WhatsApp at +1 380 900 2442. Tell us your machine model and what you need — a new machine, a used one, parts or a repair — and we will get back to you with the right answer.

Give QL the fabric types or samples, required output, current machinery and the stations to add or upgrade. QL can review a combination of its new scouring, fulling, crabbing, pre-shrinking and decatizing equipment, rebuilt pre-owned European machines and retrofit services, then define supply, commissioning and acceptance scope for a quotation. Suitable existing machines can remain in the layout. Confirm dyeing and other adjacent stages for the actual project rather than assuming a complete turnkey mill.

Wool processing runs through several stages before a finished fabric — fibre preparation (scouring, carding, combing into tops), spinning, weaving or knitting, and finishing — each using its own dedicated machinery, usually from different makers. QL specialises in the stage after spinning and weaving: at tops stage, backwashing and shrink-resist lines; in weaving, a yarn steaming autoclave; in wet finishing, milling, scouring and crabbing machines; in dry finishing, raising/shearing/brushing equipment, a fabric polishing machine, weft straightener, steaming-shrinking and decatizing machines. Carding, combing, spinning and weaving equipment are outside QL's range.
