TTL-Ongoing Research Projects

Textile Testing Lab



1. Title:

Development of sericin based nano finish for textile materials 

Scientists involved: 

Brojeswari Das, M.A. Joseph, Subhas V. Naik (CSTRI, Bengaluru); Rangam Rajkhowa, Xungai Wang (Deakin University, Australia) 

Projected Outcome:

  • Development of nano finish based on sericin for cotton, polyester and silk fabrics.
  • Antimicrobial, flame retardant, UV resistant and high absorbing textile products with the developed sericin based nano-finish.


2. Title:

Grading of tasar raw silk yarn:  Development of methods and procedure 

Scientists involved: 

Prakash N Bhat, Kiran B Malali, Naveen V Padaki, Gautam Mitra, Jayanta Ghose, Raghu K, N. S. Gahlot (CSTRI, Bengaluru); Z.M.S. Khan (CTR&TI, Ranchi) 

Projected Outcome:

  • Method of testing and grading for tasar raw silk.
  • Standard photographs for evaluation of Evenness variation, Neatness and Cleanness.
  • It would bring fair trade practices among tasar raw silk traders/weavers and reelers.
  • It would help reelers for improvement in tasar raw silk quality and helps weavers to produce quality fabric.


3. Title:

Systematic purification of unhydrolyzed  / high molecular weight  sericin  for topical skin care applications

Scientists involved: 

M.A. Joseph, S.A. Hipparagi, Subhas V Naik & K. Jaganathan (CSTRI, Bengaluru); Ravikumar G (SBRL, Bengaluru)

Projected Outcome:

Sericin is a value added byproduct, which can be recovered from the waste water generated during degumming of silk. In India sericin (22.00 % w/w) is being wasted along with the effluent generated during the chemical processing of silk.  Extraction of sericin is successful but there is no report about purification of sericin at commercial scale for the removable of heavy metals. Commercially available sericin  samples contain heavy metals such as  Copper, Cadmium, Lead, Arsenic, Chromium, etc beyond the permissible limit. Under the project titled “Characterisation of Sericin for Cosmetic Applications”. Some of the heavy metals have been removed from hydrolysed sericin. However, focussed work is required for the removal of all the heavy metals from unhydrolysed sericin.


4. Title:

Studies on correlation between sericin solubility, reelability and stripping force of tasar cocoon 

Scientists involved: 

G. Thimma Reddy, Prakash N. Bhat & Subhas V. Naik (CSTRI, Bengaluru); Z.M.S. Khan & Ajit Kumar Sinha (CTR&TI, Ranchi) 

Projected Outcome:

  • Efficiency of all the cooking methods developed so for will be measured scientifically and new optimum cocoon cooking method (Technology) for maximum recovery of raw silk  will be developed
  • Quality of Tasar  raw silk due to better cooking method   shall be improved
  • Productivity per person will improve so that industry can become economically viable.
  • Using UV spectrometer reelability can be estimated based on Sericin solubility % instead of actual reeling method.
  • New cooking formulation will be available with improved reelability.


  1. Studies on natural dyeing of eri silk/wool blends
