• Stretchable denim fabric.
• Two different types of lightweight Stretchable woven denim of 200 GSM each develope using 42 Nm indigo dyed cotton yarn as warp and 2/56 Nm wool/lycra as weft for shirts, ladies wear.
• Two varieties of wool-based single jersey knitted stretchy denim fabric of 200 and 250 GSM have been developed using Pailung Knitting m/c the yarn of 26 Ne indigo-dyed cotton used as the warp and 22 Ne wool yarn as the weft for T-shirts and pants, respectively.
• Chitosan based anti-shrinkage trials completed.
• Nacl-Kmo4 based anti-shrinkage trials ongoing
• BAP (Bisulphite adduct of polyisocyanate polyurethane anionic) trials are ongoing.
• Antimicrobial & Moisture management trials are ongoing.
• Trial work for Chemical modification of wool yarn for machine washablity with multiple approaches
  • Treatment of wool yarn with potassium permanganate in saturated sodium chloride solution (Nacl-KMN04) treatment at various temp, conc and time combinations.
  • Application of chitosan by varying different finishing parameters eg. PH, Temp, time to get optimum shrink resistance.
  • Currently, trials are being conducted for shrink proofing of wool utilizing, eco-friendly L- cysteine and proteas 16L as well as using UV radiation and a biopolymer.
