the invention discloses a technology for recovery , regeneration and reuse of soluble textiles . the technology comprises the steps of : the dissolution - controlled soluble polyester fibres are processed into soluble apparel accessories through conventional weaving , dyeing , finishing and tailoring or injection molding ; the apparels or the soluble apparel accessories are dissolved under a certain condition , on one hand , the dissolving solution is filtered and solutes are recovered to obtain a high purity of terephthalic acid and ethylene glycol , which are reused to the polymerization of the soluble polyester , and the slices of the soluble polyester are obtained to be re - spun into the soluble fibres for reuse ; on the other hand , the incompact and undissolved textiles are treated into an incompact fibre aggregation with good qualities by processes including disinfection , decolourization or redyeing , which are processed into high - quality textile fibres for reuse after drying or softly carding .
