LX600 · Chenille yarn

Published specifications

Values below come from the maintained catalogue record. The guide review date does not renew an earlier specification: read the dated source notes and confirm a current, matched configuration before comparing products.

• Send a physical reference yarn along with any photographs.
• Judge the yarn in your next process as well as on the package.

Lanxiang's current product page presents the LX600 for chenille and large-belly yarn. The illustrated brochure adds pearl yarn and says separate sections can carry separate patterns. A new fibre mix or visual effect may need development work on the machine, so agree in the quote who carries that work and how many sample rounds it includes.

Your enquiry should carry an approved reference yarn plus the details behind it: the component yarns and their count system, the finished count, the twist direction and the fabric the yarn will go into. List the visual and handling features that must match. A picture shows the look of a yarn, while the physical sample tells the maker its material and mass per length.

Lanxiang names home textiles, apparel and decorative fabrics as end uses. The LX600 produces the yarn; curtains, knitwear and upholstery are made later in the chain. Run the trial yarn through your own weaving or knitting step before you approve it for one of those uses. [1] [2]

The current page splits the machine into three drive groups: servo-driven rollers, a lifting motor with reducer that builds the package, and ring and hollow spindles under frequency-converter control. The brochure adds section-by-section control and an optional checking light. The table turns each element into a question for the configuration you plan to buy, so you know which sensors, software functions and motors the offer includes. [1] [2]

Lanxiang's earlier Chinese catalogue, with a page date of 18 November 2022, lists a count range of 1–25 Nm, delivery of 4–18.5 m/min, ring speed of 3,000–12,500 rpm and rotating-head speed of 500–24,000 rpm. The current product page has replaced that catalogue page, so ask Lanxiang to reissue these figures for the machine it quotes.

Each figure measures something different. Delivery speed is the length of yarn produced per minute. Ring speed and rotating-head speed belong to two separate rotating parts. The top ends of the three ranges seldom meet in one recipe, and spindle rpm tells you little about kilograms per shift.

Ask for one setting sheet matched to your yarn: active spindles, finished count, delivery speed and both rotational speeds. Then measure accepted yarn over an agreed run and log stops and rejects. Those numbers let you set the LX600 offer against another configuration on equal terms. [3]

The 2022 catalogue gives ten spindles per section, up to fifteen sections, a 200 mm spindle pitch and a 2.02 m section length. These figures describe the repeating frame. End units, service openings, yarn-loading routes and workshop clearances come on top of them.

The current illustrated drawing marks 2020 per section and 21400 for the whole machine, and it shows how far the cabinet doors swing open. The machine drawn may have a different section count from the one you order. The older text gives a 1.5 m width without saying whether the creel and open doors are counted, so plan floor space from a drawing of your own configuration.

Send your workshop plan and ask for an approved general-arrangement drawing for the quoted section count. It should mark the machine body, creel, electrical cabinet, open doors, loading access and maintenance access as separate zones. Set aisles and foundations only from a drawing that carries units, a revision number and installation notes. [3] [4]

Lanxiang's older Chinese catalogue describes large-belly yarn with seven segments. The current English brochure speaks of sixteen segments and, further on, sixteen cycles. The change could reflect a newer controller, a different number of programmable zones or simply new terms for the same function.

Send the repeat pattern you need and ask which machine and controller revision can reproduce it. Ask for a demonstration sample and a short written note on what a segment or a cycle means in that recipe. The offer should then list the pattern functions it includes. [2] [3]

Buyer's trial plan to agree with Lanxiang before the run

Lanxiang publishes capability and control descriptions for the LX600 but no test report on a buyer's sample. Agree the trial scope below before the run, and set the numerical pass limits with the people who own the finished yarn and the downstream product. [1] [2]

1. Fix the inputs

   Plan a trial with your own yarn lots. Name the finished count, twist direction, repeat pattern and package requirement, keep an approved comparison sample, and note the machine and controller revision.

2. Write down the recipe

   Record the active sections and spindles, roller settings, ring and head speeds, delivery speed and package-building settings. Log every adjustment made during the run as a separate condition.

3. Count accepted yarn

   Agree the run length and where samples are taken across the sections. Record accepted yarn, rejects, breaks, package changes and stopped time on separate lines, and add a fabric trial when your end use calls for one.

4. Close out the trial

   Settle any deviations against the agreed sample criteria. Collect the delivered settings, changeover instructions, parts list and inspection record before you sign the trial off as accepted.

Ask for the supply voltage, phase, frequency and connected load of the delivered configuration, plus any compressed-air or extraction needs. If the quote leaves a utility blank, ask Lanxiang whether the machine needs it.

List what comes with the machine: creel, rings, tubes, recipe functions, checking lights, commissioning, training and the first set of spare parts. Request the operating manual and the instructions for safe isolation, cleaning, clearing jams and restarting. The maintenance articles on the company website are general, so ask for a service schedule written for the LX600.

The brochure quotes an energy-saving percentage without naming the comparison machine, yarn or test method. If energy cost matters to you, meter power use during the sample run and set it against the accepted output from that same run. [1] [2] [5]
