Introduction
There are various methods for continuous fabric dyeing as well as dye fixing. When dye is directly applied, steaming (heat treatment) is required. At present the pad-steam method is widely used for continuous dyeing. To ensure stable product quality, the humidity in the steamer is kept at a constant level.
The ZR802G Zirconia High Temperature Humidity Analyzer provides excellent maintainability as it does not require the use of a sampling system, and ensures stable measurement in high temperature environments. It has been well received in the marketplace and is widely used in humidity control applications.
Expected Benefits
- Maintains the quality of the discharge process
- Ensures stable, continuous humidity measurement
- Reduces operating costs
Process Overview
The pad-steam dyeing process uses vat, reactive, acid, disperse, and other types of dyes, and includes padding, drying, fixing, washing, and re-drying steps. After padding, the fabrics are forwarded to a steamer where the dye is fixed under conditions of constant temperature and humidity.

Zirconia Oxygen/Humidity Analyzer ZR22G, ZR802G
This Oxygen concentration and humidity at high temperatures consists of a ZR22G detector equipped with a long-life and highly reliable zirconia sensor, and a converter ZR802G equipped with digital communication and data log functions.
ZR22G and ZR802G can be measured directly and continuously without a sampling device. It is easy to maintain and reduce operating costs by self-diagnosis of sensor deterioration (without using calibration gas )and replacing the heater assembly on site.
