Bio-processing of green Bamboo Textile

  1. 1. BY:- HATHISINGWALA MOH.JAVED Y ME part: III/IV Under the Guidance of:- Dr. J.N SHAH Year-2014 Department of Textile Chemistry Faculty of Technology & Engineering The Maharaja Sayajirao University of Baroda 20th AUGEST-2014 STUDIES ON BIO-PROCESSING OF GREEN BAMBOO TEXTILES
  2. 2.  Introduction  Scope Of The Present Study  Literature Review  Plan Of Work  Experimental  Results & Discussion  Summary & Conclusions  References  Acknowledgement
  3. 3.  Bio processing - great potential for industries  The bulk part of textile production migrates to the developing world, partially because of stricter environmental regulations in the industrialized countries. The developing world has the possibility to create a unique competitive advantage by promoting environmentally sustainable production process based on Biotechnology  Bamboo plant does not need any pesticides & insecticides & fungicide to grow of plant so it’s called as green plant. Textiles made of bamboo fiber are eco-friendly.
  4. 4.  Bamboo is the general name used for a number of perennial, woody-stemmed grasses  They are a popular landscape plant because they grow rapidly, are evergreens, and create a tropical or exotic atmosphere.  They are often marketed as alternative, fast- growing privacy screens. Basically bamboo is a grass; it is the world’s fastest growing ‘Woody Plant’.
  5. 5. Manufacturing process of bamboo fibers Mechanical Chemical
  6. 6. Mechanical Bamboo plant is crushed into a pulp Natural enzymes are used to form a mushy substance Fibers are combed out Fibers are spun into yarn
  7. 7. Chemically Bamboo leaves & trunk are extracted and crushed. Crushed bamboo cellulose is soaked in a solution of 20% NaOH at a temp at 20°C for 3 hours to form alkali cellulose. Then pressed to remove any excess NaOH solution. The alkali cellulose is crushed by a grinder and left to dry for 24 hours. CS2 is added to the bamboo alkali cellulose to sulphurize the compound and become jelly.
  8. 8. ……..Chemically Remaining CS2 is removed by evaporation Formation of cellulose sodium xanthogenate A diluted solution of NaOH is added to the cellulose sodium xanthogenate dissolving it to create a viscose solution consisting of about 5% NaOH and 7% to 15% bamboo fiber cellulose. The viscose bamboo cellulose is forced through spinneret nozzles into a large container of a diluted H2SO4 solution. It hardens the viscose bamboo cellulose sodium xanthogenate and reconverts it to cellulose bamboo fibers which are spun into yarns to be woven.

  11. 11. Typical Layout of Wet Spinning Process WEAVING Bamboo fibers have some properties that are not feasible i.e. it is sensitive to moisture regain and become weak as it moisture regain increase. So during the whole process the suitable rate of moisture regains is 8%-9%.

  13. 13.  Crystalline structure  According to results of XRD, although the crystalline structure of the bamboo fiber belongs to cellulose I, it is not the same as those of flax, cotton and ramie completely. XRD Graphs of the Fibers: Bamboo Fiber, Flax, Ramie and Jute Fibers
  14. 14.  In the angle of diffraction peaks, quite similar to that of wood, which shows overlapping of the diffraction peaks at (101) and (101) lattice plane.  It may be because of a high percentage of amorphous hemi cellulose and lignin in the bamboo fiber. In addition, the degree of crystallinity of the bamboo fibers is lower than those of the flax and cotton, and similar to that of jute.  The low degree of crystallinity (52.54%) for the bamboo fiber may be due to lot of substances grown with cellulose resultantly disturbing the formation of the cellulose crystalline structure during the growth of bamboo and about 20% of lignin and hemi cellulose residuals in fiber will effect testing results to some extent REFRENCE:- Dr Shah J N and Dr Shah S R. ˝Bamboo: The Green Fibre of 21st Century; Characteristics and Structure”.

  15. 15.  Degree of polymerization (DP)  DP of the bamboo fiber is close to that of the jute fiber, but lower than those of flax and ramie, and far lower than that of cotton. The lower DP would usually lead to lower tenacity for the fibers.  The DP of cellulose in fiber also is dependent on its surroundings. Higher the lignin content is in the plant, the lower the DP of cellulose may be because of disturbance created by the non-cellulose substances during polymerization, this can be proved by the group of weak cellulose characteristic absorption peaks at the wave numbers of 1032–1158cm–1 in the infrared spectrum of the bamboo fiber (figure-10), also, by fibre size The Infrared Spectra of the Fibers

  21. 21.  Main object is to produced 100% eco-friendly bamboo fabric ---- NO hazards chemicals. Save energy & eliminate harmful effect of effluent to preserve the green status of earth.
  22. 22.  Safer reactions Used of renewable raw materials  Sustain biodegradability
  23. 23.  Literature surveyed based on green status of bamboo textile.  Manufacturing of bamboo fiber  Conventional process of bamboo textile & it’s involves hazard  Development of areas of bamboo fiber processing  Green wet processing of textiles.  Bamboo processing presently is not eco-friendly  We survey the eco-friendly process & also various enzymes to eliminate sodium hydroxide with enzymes.  We survey the three natural dye which produced some herbal properties on bamboo textile.  We survey natural finishing agent ALOE VERA which impart the special antimicrobial properties on bamboo textile.
  24. 24. Out come of Literature review  oxidative bleaching are carried out using hydrogen peroxide in conventional method.  Enzymes is a specialized protein produced within an organism which is capable of catalyzing specific chemical reaction i.e. hydrolysis, oxidation, reduction, etc.  Factors affecting enzyme activity are effect of temperature, Effect of pH, Effect of activators, Redox potential,  In the present study hemicellulase, cellulase & pectinase enzymes are used to process of eco-friendly pretreatment of bamboo fabric.  Pectinases capable of hydrolyzing pectinic substances are generally enzyme complexes containing esterases and depolymerases with random or terminal activities.
