APPLICATION TECHNIQUES
- The quantities to use depend mainly on the type of dyes used and on the biggest or smaller. Read about Woven Fabric Jigger Machine
- contact with the air of the dye bath that loses reduction potential.
- with similar redox potential , provides a lower pH than ordinary sodium
- sulphur.
- This inferior alkalinity offers the following advantages:
- Smaller degradation of sensitive fibers in goods containing weaker fibres (half wool, rayon
- acetate, etc.).
- Less cellulosic fibres swelling and consequently, easy dye penetration in machines with bath
- circulation through the material.
- Another advantage of the in front of the sodium sulphur it is the easy
- removal of the remaining sulphur by means of a single cold rinsing after the dye.
- is odourless and it doesn’t produce any scent, avoiding the troubles
- working with conventional sulphur reducers.
- Reduction state can be checked on the way, dropping the dye bath on a filter paper, the stain
- should not present insoluble particles and the extended aureole , it should be coloured the same all
- over from the central part where it has thrown the drop.

Bias Line-Definition and Causes
This condition which can easily be seen on the greige goods also predominantly occurs in the single Jersey structures and, if finished incorrectly, can cause angular hem line distortion.
The main cause for this condition is knitting machine’s feeder numbers. As a general rule increasing the number of feeders increases the Bias angle.
With the increase in demand for finer and lighter weight fabrics and also increase in the number of feeders in knitting machines this problem is becoming more evident.
Due to the nature of weft circular knitting process certain Bias is inevitable and most fabric producers and garment manufacturers have come to learn to effectively manage this problem.
With new and advanced knitting machines, in order to increase the rate of production, the number of feeders has been increased, thus accentuating this angular distortion.
Preventive Suggestions
To reduce the angular distortion and have a manageable measure of Bias, the simple remedy is to reduce the number of feeders (lower than 92, preferably down to 60). This is done by disengaging some of the knitting zone’s needles. Correct finishing of the fabric as well as an adjustment in the markers to compensate for the excessive Bias are other important steps that need to be taken.
Corrective Measures
During the dyeing process, due to exposure to water and temperature and the subsequent shrinkage that takes place, the fabric will obtain a dimensionally relaxed state including its natural Bias.This is the exact state in which the fabric needs to be dried at.Any attempt to correct the natural Bias (even severe Bias), will create an unnatural condition.
The garment manufacturers can now use this fabric provided that they make the necessary adjustments in their markers to compensate for the Bias.
