CSTRI IMPROVED HANDLOOM MODEL-II

 

Frame loom                                                           Pit loom

  • improves productivity
  • improves quality

PARALLEL BEAT UP MECHANISM FOR HANDLOOMS (PIT AND FRAME LOOMS)

 

                                          Parallel Beat-up Mechanism

  • A sley with parallel beat up mechanism is introduced in handloom instead of the traditional swing type sley
  • It improves the fabric cover and retains the lustre of zari

PNEUMATIC LIFTING MECHANISM FOR HANDLOOMS

 

                                                      Pneumatic Lifting Mechanism

  • eliminates drudgery
  • longer professional lifespan of weavers
  • increase in production by 20 – 60 %
  • encourages women / new generation to take up design weaving

MOTORISED LIFTING MECHANISM FOR HANDLOOMS

Motorised Lifting Mechanism

  • helps the weaver to over come serious ailments like osteoporosis, physical pain, etc., at an early age due to reduction of physical stress
  • encourages the women to take up design weaving without any difficulty as it is easy to operate
  • encourages the new generation also to take up design weaving on jacquards
  • can be effectively incorporated in any handloom (including pit looms) not only on silk weaving but also on other fibres

BUTA MAKING MECHANISM

 

                                                            Buta Making Mechanism

  • improves productivity

PREPARATORY MACHINE FOR WARP TIE & DYE (FOR IKKAT)

 

                                                                  Preparatory Machine

  • reduces drudgery
  • improves productivity

SILK EMBROIDERY THREAD

Silk Embroidery Thread

  • Development of silk embroidery thread for use in the production of embroidered silk products contributes to the production of all silk products which in turn can fetch a better price
  • A variety of silk embroidery yarns were developed, catering to the requirements of both hand and machine embroidery sector
  • These silk embroidery yarns are strong and display great tensile strength compared to the existing yarns used for embroidery

PRODUCTION PROCESSES OF SILK NON-WOVENS FROM DIFFERENT SILKS AND SILK WASTES

 

  • Possibilities of production of silk non-wovens from different silks and silk wastes have been explored
  • The processes have been standardised
  • Varieties of silk non-wovens were developed from the silk wastes generated during weaving in rapier looms (selvedge waste), raw silk testing (seriplane waste), cooking and reeling waste (cooker & reeler waste), Eri noil waste (Eri Mill spinning waste)
  • These silk non-woven were used to prepare products like bed covers, vanity bags, mobile covers, table mats and wall hanging etc.

 

 

APPLICATION OF FIRE RETARDANT FINISH FOR SILK FABRICS


                  Fire Retardant Finish

  • The standard recipe and optimum process parameters for the application of fire retardant finish for silk fabrics has been developed


APPLICATION OF STAIN GUARD FINISH TO SILK YARN AND LOOM FINISHED FABRICS

 
                                                                     Stain Guard Finish

  • The standard recipe and optimum process parameters for the application of stain guard finish has been successfully developed for both mulberry and tasar silk yarn and fabric
  • This finish can withstand 15 to 20 washes in case of all the varieties of the fabrics studied

APPLICATION OF LAC DYES ON MULBERRY SILK

  • A recipe for dyeing of mulberry silk with lac dye with out using any mordent has been developed

STANDARDISED DYEING OF ERI SPUN SILK YARN

  • Suitable methodology and recipe for degumming/scouring, bleaching and dyeing for both hand and mill eri spun silk yarn have been developed

APPLICATION OF NATURAL DYES ON SILK

  • With the increasing demand for natural and eco friendly materials, studies on application of natural dyes on silk were initiated at the Institute.
  • The appropriate extraction and dyeing techniques for natural dyes obtained from plants, insects, mud, etc. has been developed.

APPLICATION OF NEEM LEAF EXTRACT ON SILK AS DYE, PRINT COLOUR AND FINISHING AGENT

  • Colour has been extracted from neem leaves through aqueous extract method and used as source of colour to dye on mulberry and tasar fabrics
  • Neem powder has been used in printing, both block and screen on mulberry and tasar fabrics
  • Neem has been used as finishing agent on silk cotton blend fabrics

APPLICATION OF CREASE RESISTANCE FINISH TO SILK FABRICS

  • Recipe and methodology for imparting crease resistant finish to silk fabrics has been developed

STANDING BATH DEGUMMING OF SILK

  • A standing bath method for degumming without affecting the quality of silk and at the same time improving the economics of degumming has been developed
  • This process can contribute not only towards the conservation of water, energy and chemicals but also towards reduction in pollution

SAND WASH FINISH TO SILK FABRICS

  • An appropriate process to impart sand wash finish to different types of silk fabrics has been developed
  • The use of this finish gives soft feathery feel to the fabrics
