Tonello G1 420 LD3 Garment Dyeing Machine

What the G1 420 dyes

The Tonello G1 420 LD3 is a garment dyeing machine: a rotary drum that dyes finished garments and parts rather than yarn or flat fabric. It runs Tonello's patented high-speed open system, and with the UP system fitted it dyes at a liquor ratio as low as 3:1, which is where the water, chemistry and energy savings come from. The LD3 is the low-speed spin cycle for gentle handling, and the same G1 series offers a medium-speed MD3 spin and models from 130 up to 510.

Buyers call this machine by different names depending on the trade. You might know it as a garment dyeing machine, an industrial dyeing machine, a garment dye machine, a low liquor ratio dyeing machine, a denim dyeing machine or a rotary dyeing machine. They all point to the G1.

Built for garment dyers and laundries

The G1 is for plants that dye the made-up garment: denim laundries and washing units, knitwear and t-shirt dyers, sportswear and athleisure producers, and footwear and home-textile dyers. Garment dyeing gives the soft hand and the on-trend, lot-to-lot shade variation that piece dyeing cannot, and doing it in-house puts colour, lead time and quality under your own roof. A color kitchen doses dyes and auxiliaries the same way every batch, and central computer control keeps the recipe consistent.

The choice between the LD3 low-speed and MD3 medium-speed spin comes down to how delicate the garment is, and the UP and Steam Pocket options let you tune the machine for water use and heating. Our team sizes the right G1 model and options with the factory for your fabric and batch.

Low-liquor dyeing vs conventional high-ratio dyeing

A conventional garment dyeing machine floods the drum, often at a liquor ratio of 8:1 or higher, which means heating and treating a lot of water for every kilo of garment, then sending it to effluent. The G1 with the UP system works at a ratio as low as 3:1. Less water in the bath means less water to heat, less salt and chemistry to dose, faster cycles and a smaller effluent load, which matters in India where dyeing units face real pressure on water use and discharge. The open system and color kitchen also hold the shade steady from lot to lot.

• Less water: a 3:1 liquor ratio uses a fraction of the bath of a high-ratio machine.
• Lower energy: less water to heat per batch, with Steam Pocket indirect heating.
• Less chemistry and effluent: a smaller bath needs less salt and dye and discharges less.
• Repeatable shades: the color kitchen and central control keep colour steady lot to lot.
• Right spin: LD3 low-speed for delicate pieces, MD3 medium-speed where it suits.

Industries that use the G1

Any plant that colours finished garments is a fit. Tonello builds the G1 for:
