New development:

Green Cotton Process

STDP Process

Combined Dyeing Process

 

Green Cotton Process

It is bio-sustainability and economy process for scouring of cotton and cotton blends. It is Cellulolytic Pectate Lyse enzyme design to scouring and bio-finishing in a same bath. There is no need to use harsh chemicals like Hydroger Peroxide and caustic for scouring and no need to scouring at higher temperature. You can do it at 60 °C temperature for 60 minutes getting good absorbency required for dyeing.

 Green Cotton Process can gives benefits like

Process Simplicity

  • Combined Scouring and de-pilling. The ability of this enzyme to perform fabric cleanup under neutral pH allows combining scouring and De-pilling in a single bath. This reduces processing time and enables increased production throughput.

 

  • No pH adjustment. Cottonese BT CNC works optimally over the entire range of potential incoming process water pH Typically, no time is necessary for adding pH adjustment chemicals.

 

  • Reduce Process Time as scouring and de-pilling occurs in the same bath with neutral condition it reduces pre-treatment time significantly.

  • Reduced Water. In a single bath Cottonese BT CNC performs scouring and de-pilling together. So at least 3 baths can save.

 

  • Save Energy. Cottonese BT CNC can work as low as 60 °C. Incoming process water needs minimal heating to bring the bath into operating temperatures, reducing time (enabling increased production) and saving energy.

 

  • Ecological Benefits with savings of water and energy this process eliminates most harsh part of dyeing cycle and this is high temperature caustic scouring. So less impact on Effluent Treatment Plant.

 

High Quality Fabric

  • Preserved fabric strength and weight.

Enzymatic Scouring and De-pilling process provides surface cleanup without aggressive change to the underlying fabric fibers. This provides New development:

higher fabric strength and weight retention when compared to traditional caustic scouring and cellulase de-pilling process.

 

  • Reduce Process Loss. Scouring and de-pilling with Cottonese BT CNC results in exceptionally clean fabric surfaces including oil, wax and hairiness. Due to gentle action Cottonese BT CNC on the surface of the fabric, it retains more natural structure than classic scouring process. It reduce the use of dye to achieve desired color, or the same amount of dye to increase dye color intensity.

 

  • Consistent Fabric quality. Cottonese BT CNC gives reproducible fabric look and feel even under moderate variations in processing pH, temperature, and time. This product can provide the process robustness required to minimize time consuming and costly dyeing rework.

 

  • Fabric Appearance and feel. This process imparts gorgeous look and very lofty hand-feel to the fabric.

Time Saving Dyeing Process

It is a process of Bio-finishing in dye bath. By using unique Cellulase enzyme also known as neutral enzyme can use in dye bath by combined the process.

There is no effect on dyes and other dyeing auxiliaries so it can perform its operation easily. The TSDP can gives benefits like

 

Process Simplicity

  • No pH adjustment. Cottonese BT NC works optimally over the entire range of potential incoming process water pH’s. Typically, no time is necessary for adding pH adjustment chemicals.
  • Combined finishing and dyeing. The ability of this enzyme to perform fabric cleanup under neutral pH allows the possibility to combine bio-finishing and dyeing in a single bath. This reduces processing time and enables increased production throughput.
  • Saves time & Energy. The ultimate goal of this process can save time more than two hours which have a huge impact in cotton dyeing process. It also saves energy now a days which has a significant role in our dyeing process.

High Quality Fabric

  • Preserved fabric strength and weight.

Enzymatic finishing provides surface cleanup without aggressive change to the underlying fabric fibers. This provides higher fabric strength and weight retention when compared to traditional cellulase processing.

  • Increased dye uptake. Bio-polishing with Cottonese BT NC results in exceptionally clean fabric surfaces, either reducing the use of dye to achieve desired color, or the same amount of dye to increase dye color intensity.

COMBINED DYEING PROCESS

It is a solution of peroxide killing process as well as bio-finishing in a simple and easy way. This process no need to killing the peroxide in a separate bath as well as no need for bi0-polishing in separate bath. You can do it in single bath.

It is a Catalytic Cellulase Enzyme which can perform peroxide killing as well as bio-finishing. So it saves no of baths, time, energy as well as money of course.

Process Simplicity

  • No pH adjustment. Cottonese BT CC works optimally over the entire range of potential incoming process water pH’s. Typically, no time is necessary for adding pH adjustment chemicals.
  • Combined finishing and dyeing. The ability of this enzyme to perform fabric cleanup under neutral pH allows the possibility to combine bio-finishing and dyeing in a single bath. This reduces processing time and enables increased production throughput.
  • Saves time & Energy. The ultimate goal of this process can save time more than two hours which have a huge impact in cotton dyeing process. It also saves energy now a days which has a significant role in our dyeing process.

High Quality Fabric

  • Preserved fabric strength and weight.

Enzymatic finishing provides surface cleanup without aggressive change to the underlying fabric fibers. This provides higher fabric strength and weight retention when compared to traditional cellulase processing.

  • Increased dye uptake. Bio-polishing with Cottonese BT NC results in exceptionally clean fabric surfaces, either reducing the use of dye to achieve desired color, or the same amount of dye to increase dye color intensity.
