Textile-Yarn Paraffin Wax For Spinning Waxing Discs Price Per Kg

Textile-yarn paraffin wax for spinning waxing discs price per kg depends on grade, oil content and order volume, not on a single published rate — mills price it against monthly wax benchmarks and their own consumption per kilogram of yarn. This guide explains what determines that price, which paraffin properties matter to a spinning mill, and what to check before you order. It draws on published textile-lubrication research and the ASTM/ISO test methods mills use to specify wax, cited throughout.

Who this guide is for

This is written for three readers. The spinning mill or knitting-plant buyer sourcing waxing-disc paraffin and comparing price per kilogram across suppliers. The textile engineer or quality manager who needs to specify congealing point and oil content correctly before approving a supplier. And the procurement lead at a trading or converting business who needs a defensible basis for a purchase order, not a guessed number. Each gets a dedicated answer below.

What waxing discs actually do to yarn

Waxing discs apply a thin, controlled film of solid paraffin wax to yarn as it passes through winding or knitting machinery. According to European Journal of Engineering and Applied Sciences (2024), paraffin-waxing "must be applied in knitting process to reduce the friction among knitting machine elements, especially between the yarn and needle." Their study ran five different commercial paraffin waxes through identical winding-machine settings on ring-siro combed and melange 100% cotton yarns, confirming that wax choice measurably changes downstream yarn behavior.

The same friction problem shows up earlier in the process. According to the Australian Wool Education Trust (2009), ring spinning is inherently slow and expensive because each spindle is a low-production unit, so mills invest in post-spinning steps — including waxing — to prepare long, fault-free lengths of yarn for weaving or knitting. Waxing discs are one of the levers a mill has to protect that downstream yield.

Free-running versus power-driven waxing units

Not every waxing disc setup works the same way. According to the International Institute for Cotton (1975), yarn lubrication for weft knitting is applied by solid wax using either free-running (gravity) waxing units or power-driven waxing units, as well as by emulsions and coning oils. A wax that performs well on a gravity disc does not automatically suit a power-driven unit running at higher throughput — this is a specification question to raise with your supplier before committing to volume.

What determines price per kilogram

Paraffin wax price per kilogram tracks feedstock and refining costs, plus the properties a mill specifies. Three properties drive both performance and cost conversations: congealing point, oil content and melting point.

Congealing point

According to ASTM International (2025), ASTM D938 measures the temperature at which a cooling wax sample develops a "set" or resistance to flow, and congealing point is a property of interest to many petroleum wax consumers. The ISO (1980) equivalent, ISO 2207, specifies the same determination and remains current after review in 2023.

Oil content

According to ASTM International (2017), oil content "may have significant effects on several of its properties, such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and oil straining." ASTM D721 covers waxes with a congealing point of 30°C or higher containing not more than 15% oil — a range directly relevant to a waxing-disc specification.

Melting point

According to ASTM International, melting point by cooling curve (ASTM D87) "is a test that is widely used by wax suppliers and consumers," particularly for petroleum waxes that are highly paraffinic or crystalline in nature.

How mills benchmark the market price

Mills and traders do not price textile-yarn paraffin wax in isolation. According to Argus Media, Argus Global Waxes publishes monthly independent price assessments for paraffin wax, liquid and slab wax, and feedstock slack wax across Asia, Europe and the Americas. A price-per-kilogram quote that cannot be reconciled against a benchmark like this is a quote worth questioning.

Verifying wax at the border or in the lab

According to the U.S. Customs and Border Protection, chapter 34 laboratory methods include method 34-05, the dropping-point test (ASTM D3954), and method 34-07, quantitation of paraffin content by high-temperature capillary gas chromatography. These are the kinds of checks a buyer or its customs broker can request when a shipment's composition needs independent confirmation.

What to check before you order

• Ask for the congealing point (ASTM D938 or ISO 2207) against your waxing-disc process requirement.
• Confirm oil content is within the range your winding or knitting equipment tolerates.
• Request the melting point by cooling curve (ASTM D87) alongside the congealing point.
• Check whether your waxing units are free-running (gravity) or power-driven, and confirm the wax has been tested for that setup.
• Benchmark the quoted price per kilogram against a published market reference such as Argus Global Waxes.
• Ask what volume break points apply — price per kilogram typically shifts with order size.
• Confirm packaging format (slab, block, or disc-ready) matches your production line.
• Clarify lead time and origin before locking a price, especially for repeat, scheduled orders.

Textile-yarn paraffin wax price per kg: a guide for repeat buyers

For a mill buying on a recurring schedule, the textile-yarn paraffin wax for spinning waxing discs price per kg overview above is only half the picture — consistency between orders matters as much as the initial quote. A tips-driven approach works best: fix your congealing point and oil content specification once, request the same test data on every shipment, and re-benchmark price per kilogram each quarter against the published market reference rather than negotiating from memory.

Working with BHD Group

BHD Group operates two divisions, BHD Chemical and BHD Sourcing, under one accountable house. Paraffin Wax sits in the Waxes family alongside Slack Wax and Petroleum Jelly — the range this business leads with. We supply Turkish-origin paraffin wax processed to origin, and we quote price per kilogram against the specification a mill actually needs: congealing point, oil content and melting point, not a generic grade name. If you are evaluating Textile-Yarn Paraffin Wax For Spinning Waxing Discs Price Per Kg for a waxing-disc line, send us your process parameters and order volume and we will work the quote from there.
