Automatic Atmospheric Large-Roll Jigger Dyeing Machine: SWR1000 Buying Guide

When Do You Need an Atmospheric Large-Roll Jigger Dyeing Machine?

An atmospheric jigger dyeing machine moves open-width fabric back and forth between two rollers through a small dye bath at normal pressure, typically up to about 100 degC. You need this class of machine when your goods are cellulose and protein fibres - cotton, linen, silk, rayon - and other fabrics that dye well without pressure. The SWR1000 adds a large-roll layout and a high degree of automation on top of that principle.

It is suited to open-width fabrics, silk, cotton, nylon, rayon and synthetic filaments, and runs disperse, sulfur, vat, direct and reactive dyes as well as scouring, bleaching and washing. Because it works under reliable constant tension and constant linear speed, it is the kind of open-width jigger dyeing machine dyehouses rely on for small batches and frequent style changes.

If your mill runs woven goods that must stay open-width and flat through dyeing - rather than rope-form jet dyeing - an atmospheric large-roll jigger like the SWR1000 is the standard choice.

Core Parameters & Technical Data

Automatic pass counting, automatic reversing, automatic direction changing and automatic stop, so each cycle runs without constant operator intervention.

High level of automation: running performance is more stable, reliable and accurate - one of the leading atmospheric jiggers in China.

Mechanical and electrical control absorbs advanced foreign jigger technology, then is re-engineered to domestic market needs and years of customer feedback.

Built with advanced technology, precision machining and strict inspection; its reliability, economy and practicality won the Gold Medal at the Fifth Patent, New Technology and New Product Expo.

Constant tension and constant linear speed are maintained, which is essential for level shades on woven fabric.

Process range: disperse, sulfur, vat, direct and reactive dyes, plus scouring, bleaching and washing, all under atmospheric conditions.

How to Choose the Right Atmospheric Jigger

First confirm the process is atmospheric. If you dye cotton, silk, nylon, rayon or synthetic filaments up to about 100 degC, an atmospheric jigger is right; polyester needs a high-temperature high-pressure jigger instead.

Match automation to your staffing. Automatic pass counting, reversing, direction change and stop reduce operator error and keep shades repeatable from batch to batch.

Check constant tension and linear speed control. On delicate woven and silk fabrics, speed or tension drift shows up as shade variation and creasing that is hard to correct later.

Confirm the dye classes you run. The SWR1000 covers disperse, sulfur, vat, direct and reactive dyes plus scouring, bleaching and washing, so one machine carries a wide process mix.

Verify fabric width and roll size against your product range, and tell us the widest fabric you run so we confirm the right configuration.

Buy from a production factory, not a trader - commissioning, spare parts and operator training are part of the machine's working life.

Common Mistakes Buyers Make

Buying an atmospheric jigger for polyester. Polyester needs temperatures above 100 degC, which a normal-pressure machine cannot reach; specify an HTHP jigger for synthetics.

Underestimating the value of automation. Manual reversing and counting invite errors on long batches; automatic pass counting and reversing pay back quickly in consistent shades.

Ignoring constant tension on delicate goods. Silk, nylon and rayon distort or crease if tension drifts between passes.

Not listing all dye classes and pre-treatment processes up front. If you also need scouring, bleaching and washing in the same machine, say so at selection.

Going by price alone from an intermediary. A machine without after-sales support can stall production when it needs commissioning or parts.

Why Buy from Wuxi Runda

We are a production factory founded in 2004, located in Qianzhou, Wuxi - at the heart of Jiangsu's dyeing machinery industrial cluster, with component suppliers and skilled workers nearby.

We cooperate with textile research institutes and technical colleges year-round, and design and develop our own series after absorbing the advantages of jiggers from Japan, Denmark and Italy.

We build machines for small batches, multiple varieties and low energy consumption, with reliable and stable performance - the practical profile of most modern dyehouses.

Our equipment is exported to Vietnam, India, Bangladesh, Indonesia, Pakistan, Japan, Thailand and other Southeast Asian markets, backed by complete after-sales service including installation, commissioning, spare parts and training.

Frequently Asked Questions

Which fabrics can the SWR1000 atmospheric jigger dye?

It is suited to open-width fabrics, silk, cotton, nylon, rayon and synthetic filaments, running disperse, sulfur, vat, direct and reactive dyes as well as scouring, bleaching and washing under atmospheric conditions.

Can the SWR1000 dye polyester?

No. It runs under normal pressure, so it suits cotton, silk, nylon, rayon and similar goods. Polyester and other synthetics need a high-temperature high-pressure jigger such as our GR680 series.

What automation does the machine have?

Automatic pass counting, automatic reversing, automatic direction changing and automatic stop, with constant tension and constant linear speed for stable, repeatable results.

Is it suitable for small-batch, multi-variety dyeing?

Yes. Its high automation and wide dye/process range are exactly aimed at dyehouses that run small batches and frequent style changes.

How do I confirm the right width and configuration?

Tell us your fabric type, widest fabric width and the processes you need. Our engineers will confirm the matching SWR1000 configuration and send technical parameters.
