Desizing and its Uses

What is Desizing?

Desizing is one of the key processes for the wet treatment pre-treatment of cotton fabrics. Before dyeing and printing, it is essential to remove the formats coated on the fabric.
The enzymatic desizing process is friendly with people, machines, and the environment. Four different types of machines have been used to study the aspects and consequences of enzymatic decidation. Unlike acidic and oxidative, biodegradation of size does not harm the fabric and does not emit greenhouse gases (CO2), respectively.
The highest desizing quality was observed, the degree of desizing on the TEGEWA scale was 8. The amount of desizing agent used was 0.5 to 4.0 kg / 1000 liters. In the winch (batch) desizing, the degree of whiteness was 76%, which is 1.5 times higher than the gray fabric, but the buffer steam desizing process (continuous) showed a degree of 69% whiteness, which is 1.35 times higher than gray fabric.
The competitive results were obtained in a continuous process with an efficient time. This article reveals the advantages, processes, and results of green technology in the wet textile industry.


Application of Desizing in Garments Industry.

Starch is carried out in order to eliminate the sizing of the warp threads of woven fabrics. Warp yarns are coated with desizing  agents lead to weaving to reduce their frictional properties, reduce yarn breaks on the loom and improve weaving productivity by increasing internal infiltration speeds. The sizing material present on the warp yarns can act as a resist against dyes and chemicals in the wet treatment of textiles. It must therefore be removed before any subsequent wet treatment of the fabric.

Objects of Desizing:

  1. To extract the starch material from the fabric.
  2. To increase the soaking power of the fabric.
  3. To increase the fabric affinity to the dry chemicals.
  4. To make the fabric ready for the next process.
  5. To increase the glow of the fabric increase dyeing and printing.

    If you are looking for desizing agent for your washing unit. We are a leading jeans washing chemical supplier in Delhi. Eureka Chem India, supplying non-hazardous materials replaced by amylase, an environmental friendly material, that can be applied for the desizing of cotton fabrics.
