Project Report for Yarn Gassing Machine
Fabric manufacturers and garment exporters prefer the smoother, more lustrous yarn that results from singeing, which involves passing yarn through a gas flame at 400–1,000 meters per minute to burn off protruding fiber ends that cause hairiness and pilling.

What Is Yarn Gassing / Singeing?
Yarn gassing, also known as yarn singeing, is a specialist textile finishing procedure that improves the surface quality of yarn. Unlike ring spinning, open-end spinning, and air-jet spinning, yarn gassing is a post-spinning procedure. This method involves passing yarn at high speeds across an open gas flame (LPG or natural gas) or over electrically heated plates, with speeds typically ranging from 400 to 1,000 meters per minute.
The controlled heat burns away the short projecting fiber ends (hairiness) from the yarn surface while preserving the main yarn structure, resulting in a cleaner and more uniform appearance.
The key advantages of yarn gassing are reduced yarn hairiness, greater pilling resistance, increased luster, better dye absorption, and brighter fabric colors. Gassed yarn creates smoother materials with a superior finish, making it ideal for high-end textile applications.
It is commonly utilized in the manufacture of fine cotton and cotton-polyester mix fabrics, such as premium shirting materials, luxury bed linen, hosiery items, and export-oriented apparel. The technique assists manufacturers in meeting international quality requirements by supplying fabrics with a cleaner surface, improved look, and increased customer appeal.
Yarn Gassing vs Yarn Spinning — Critical Distinction
This distinction must be clear in the project report:
Yarn Spinning | Yarn Gassing/Singeing | |
What it does | Converts raw fibre into yarn | Burns off hairiness from spun yarn |
Input | Cotton/polyester fibre | Spun yarn (cone or package) |
Output | Yarn cone/bobbin | Gassed (singed) yarn cone |
Process | Mechanical (drawing, twisting) | Thermal (gas flame) |
Equipment | Ring frame, open-end machine | Gas singeing machine + winder |
Stage in textile chain | Earlier (fibre → yarn) | Later (yarn → fabric preparation) |
A yarn gassing unit is a textile job work service — it does not spin yarn. It receives yarn from spinning mills or traders, processes it through gassing, and returns/sells gassed yarn.
Business Model — Job Work and Own Processing
Job work model (most common): Spinning mills, yarn traders, and fabric manufacturers deliver yarn to the gassing unit for processing. The gassing unit charges a job work rate per kg, which is the amount of yarn handled. Job work rate ranges from Rs.4 to Rs.12 per kg of yarn gassed, depending on yarn count, speed, and market. Revenue per machine, per day: Machine running at 600 m/min for 20 hours per day, processing 20s count cotton: 500-800 kg per head.
Own yarn gassing and trading: The unit buys gray (unsinged) yarn at market price, gasses it, and then sells it at a premium. Margin equals the price difference between unsinged and singed yarn minus processing costs. Premium for gassed yarn: Rs. 8-20/kg over unsinged yarn (depending on count and market).
Combined: Job labor for established spinning mills and own trading with spot margin opportunities

Yarn Gassing Machine — Equipment and Technology
Gas singeing machine (primary equipment): A gas singeing machine consists of:
- Creel (yarn supply from input cones or packages)
- Tensioning and guide rollers (Yarn path control)
- Gas burner unit (LPG/NG flame with fine temperature and position control).
- Water trough or air blast (quench unit — extinguishes any remaining glow immediately after singeing)
- Winding head (winds singed yarn onto output cones or packages)
Machine configurations include two, four, six, and eight heads, each of which processes one yarn end at the same time.
Capacity example (6-head machine @ 700 m/min, 20 hours/day, 20 second count): 6 ends × 700 m/min × 60 × 20 hours = 5,04,000 meters/day. At approximately 800 meters/kg (20s count): 630 kg/day per 6-head machine
Reputable machine manufacturers include Osthoff-Senge (Germany), Xetma Vollenweider (Switzerland), and local manufacturers (Coimbatore, Surat, and Ahmedabad).
Imported (used/refurbished) machines cost between Rs.8-25 lakh each. Indian-made: Rs. 5-15 lakh per machine, depending on head and automation.
Supporting Equipment: LPG/PNG connection and gas panel UPS/stabilizer (constant voltage for electronic controls) Compressor (for pneumatic tensioning) Humidity control (yarn breaks increase at extremely low humidity)
Where Is Yarn Gassing Concentrated in India?
- India’s yarn-gassing business is located in big textile clusters.
- Coimbatore, Tamil Nadu, is India’s largest yarn spinning and processing hub, with a strong need for yarn gasification services from spinning mills.
- Tiruppur, Tamil Nadu: A knitwear export hub with high demand for gassed yarn for hosiery and T-shirt fabric.
- Surat, Gujarat: Yarn gassing for polyester-cotton and viscose hybrid yarns.
- Ludhiana, Punjab: Knitwear and hosiery, including gassed yarn for winter knitwear.
- Cotton weaving clusters in Erode and Salem, Tamil Nadu, use gassed yarn to produce superior shirting and home textiles.

Frequently Asked Questions
Yarn gassing (singeing) is a textile finishing procedure that uses a gas flame to burn off projecting fiber ends (hairiness) from already-spun yarn at speeds ranging from 400 to 1,000 metres per minute. Yarn spinning is an entirely distinct, earlier process that converts raw fibre into yarn. A yarn gassing unit is a textile job service that processes yarn obtained from spinning mills but does not spin it.
Gassed yarn has less hairiness (fewer projecting fiber ends), a higher luster and shine, better dye penetration (brighter, more even color), and improved pill resistance in the completed fabric. Premium shirting textiles, delicate bedlinen, export-quality hosiery, and high-count woven fabrics all call for gassed yarn to achieve a cleaner, smoother surface look.
Depending on the yarn count and machine settings, speeds range from 400 to 1,000 metres per minute. Finer yarns (higher count) are often run at slower speeds for thorough singeing, but coarser yarns can run faster. At 700 m/min on a 6-head machine running 20 hours per day, roughly 630 kilograms of yarn are gassed per day.
The price per kg of yarn processed ranges between Rs.4 and Rs.12, based on region (textile cluster demand), yarn count (finer yarns command higher rates), machine quality, and market rivalry. In high-demand clusters such as Coimbatore and Tiruppur, prices range from Rs.6 to Rs.12 per kilogram. In smaller marketplaces, prices range from Rs.4 to Rs.8 per kilogram. Own trading margin (gassed minus unsinged yarn price minus processing cost): Rs.8-20 per kilogram, depending on count and market timing.
Liquefied petroleum gas (LPG) or piped natural gas (PNG). PNG is much less expensive than LPG where accessible, with gas costs falling from Rs.2-2.50/kg (LPG) to Rs.0.80-1.50/kg (PNG). Locating near PNG availability significantly enhances unit economics. Gas is the main variable operational expense in yarn gassing.
Yes. For small units (Rs.8-18 lakh), consider PMEGP manufacturing (15-35% subsidy) or Mudra Tarun. Medium unit (Rs.18-45 lakh): PMEGP (up to Rs.50 lakh) or an MSME term loan. Larger units: MSME term loan. Working capital for own trading model (yarn buying) requires a separate CC credit. CA-certified project report with machine capacity calculation, job work versus trading model, and accurately modelled gas costs is required.
