Example 1

[0077] Waste fibrous materials were pretreated to remove all the impurities. The impurity free waste fibrous matter was then subjected to trimming using mechanical treatment to obtain fibers of length 200 mm-100 mm, or as per need. Subjected the obtained fibers to a mechanical treatment to loosen and clean the fibers. The fibers are then thorough washed during and while being densely packed into a perforated carrier with fluidized pressure. The carrier packed densely with fibers is then placed into a vessel having enzyme and water solution. The process is carried out for 30 minutes depending upon the nature of impurities. The fibrous materials: water: enzyme ratio is on an average 1:3.3:0.015. The water is then drained and filled with new water at an average of fiber to water ratio of 1:2.8. The water is heated to 80 degree Celsius and subjected to steam explosions in regular intervals at 15 bar, 5 times for 120 seconds. The fiber water cake is then ready for chemical treatment, where either of the one process is performed depending upon the chemical constituents of the raw material, mechanical land physical properties. A step of dyeing and stabilizing the fiber can be done at this step if needed. The obtained white solidified cake is then placed into a hydroextractor to reduce the average moisture content to 30%. The densely packed cake is then opened mechanically to break it back into fibers. The fiber with moisture is then subjected to Radio frequency to reduce the average moisture level to around 10%. The fibers are assessed at this stage for its chemical properties, physical properties and softness. Based on results the fibers are then exposed to specially designed short bast softening machine that smoothens the surface and sprays it with enzyme or oil-based or wax-based emulsifier/lubricant. The fibers are the passed-through a mechanical machines having set of wires and directional openers for removal of lint, further softening and parallelization of fibers. If the application requires blending of any fibers, then the blends can be made at this stage. If there is a need to manipulate the length, then the parallel fiber sliver is cut in desired length as per application with highest consistency. If not, the slivers can be used directly to be spun into yarn.

[0078] The chemical treatment in the above method comprises of: [0079] a) Bath treatment A wherein if the waste material is high in cellulosic content, only one bath treatment is done. In this treatment an oxidizing agent with a catalyst is used or an alkali treatment is done for 2 hours. The same is neutralized and softened in the same batch with acid and treated with an enzyme solution. [0080] b) Bath B treatment wherein if the waste material is average rigid and has a high lignin concentration, double alkali treatment is done. Bath treatment A along with softening treatment is performed after draining the water after first alkali treatment. [0081] c) Bath treatment wherein if the waste is very rigid and has even higher lignin content, bath treatment B is conducted. if the waste material is average rigid and has a high lignin concentration, double alkali treatment is done. Bath treatment A along with softening treatment is performed after draining the water after first alkali treatment in separate baths. [0082] d) Bath treatment D wherein if the waste is highly rigid and has extremely high lignin content. the alkali treatment is done twice, one with and one without bleaching agent along with softening treatment.

[0083] In case of higher impurities any of the below is preceded by pickling.

[0084] All or either of the bath options A, B, C, and D can be chosen depending upon the type of waste matter. This the case for the sub-steps of these bath options as well i.e., one of the sub-steps or all of the sub-steps can be chosen as well. The choice of treatment purely depends upon the type of waste matter or the fibrous matter.

Example 2

[0085] Waste fibrous materials were pretreated to remove all the impurities. The impurity free waste fibrous matter was then subjected to trimming using mechanical treatment to obtain fibers of length 100 mm, or as per need. Subjected the obtained fibers to a mechanical treatment to loosen and clean the fibers. The fibers are then thorough washed during and while being densely packed into a perforated carrier with fluidized pressure. The carrier packed densely with fibers is then placed into a vessel having enzyme and water solution. The process is carried out for 30 minutes depending upon the nature of impurities. The fibrous materials: water: enzyme producing microbes ration is on an average 1:4:0.02. The water is then drained and filled with new water at an average of fiber to water ratio of 1:3.2. The water is heated to 110 degree Celsius and subjected to steam explosions in regular intervals at 8 bar, 3 times for 220 seconds. The fiber water cake is then ready for chemical treatment, where either of the one process is performed depending upon the chemical constituents of the raw material, mechanical land physical properties. A step of dyeing and stabilizing the fiber can be done at this step if needed. The obtained white solidified cake is then placed into a hydroextractor to reduce the average moisture content to 40%. The densely packed cake is then opened mechanically to break it back into fibers. The fiber with moisture is then subjected to Radio frequency to reduce the average moisture level to around 20%. The fibers are assessed at this stage for its chemical properties, physical properties and softness. Based on results the fibers are then exposed to specially designed short bast softening machine that smoothens the surface and sprays it with enzyme or oil-based or wax-based emulsifier/lubricant. The fibers are the passed-through a mechanical machine with set of wires, openers, felts for removal of lint, further softening and parallelization of fibers. If the application requires blending of any fibers, then the blends can be made at this stage. If there is a need to manipulate the length, then the parallel fiber sliver is cut in desired length as per application with highest consistency. If not, the slivers can be used directly to be spun into yarn.
