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.

The invention relates to a method for the treatment and utilization of waste liquor containing at least polyester degradation products and originating from an alkaline pulping process for the extraction of cellulose raw material from blended textile waste which contains at least a cellulose component and a polyester component. In order to make the method environmentally friendlier and more resource-efficient, it is proposed that the method comprises the following steps: the evaporation of water from the waste liquor in order to precipitate the polyester degradation product from the waste liquor and to obtain a two-phase mixture having an aqueous phase and a solid phase including the polyester degradation product, b) the separation of the solid phase from the liquid phase, and c) the thermal/energetic utilization of the solid phase.

A process and plant for making wadding or fiber flocks starting from a padded textile product, either recycled or resulting from surplus production, wherein processing is carried out together and simultaneously of all the textile materials forming the same starting padded product. Compared with the known embodiments of the sector, the process and plant of the invention, in an economical, rapid and entirely mechanized way, allow wadding or fiber flocks to be produced that can be used as insulating padding in the clothing and furnishing sectors.

A fibrous pant stalk decorticator is disclosed. The decorticator includes a feeding device a breaker roll having a first plurality of blades, and a skutcher roll having a second plurality of blades. The skutcher is positioned such that the first and second pluralities of blades overlap. A plurality of air outlets pass through the blades and are configured to provided pressurized air to the fibrous plant stalk as it is passed through the decorticator.

A fabric for use in arc and flame protection, and a process for producing a fire resistant fabric are provided. The fabric includes at least 70 wt % aramid fiber; less than 40 wt % modacrylic; 8 wt % nylon; and 2 wt % anti-static. The process includes shredding recycled fire resistant garments into fibers; creating yarn from the shredded fibers; weaving the yarn into fabric; and knitting the yarn to produce new garments. The fabric may be used to produce fire-resistant garments worn by workers in many industries such as the oil and gas.

Disclosed are textile products such as towels and peshtemals used in baths, spas, saunas, hotels, swimming pools and beaches. The textile products include pile yarn and warp yarn created by blending the cotton fiber produced by recycling textile wastes made of 100% cotton, with the polyester (RES) fiber produced by recycling plastic materials.

What is shown is a method for the recovery of raw materials from blended textile wastes, which includes the following steps in the given order: a) providing blended textile waste that includes at least a cellulose component and at least a polyester component, b) treating the blended textile waste in an aqueous treatment solution in order to depolymerize the polyester component and dissolve it in the treatment solution, c) separating the cellulose component from the treatment solution and recovering a cellulose raw material, d) filtering the treatment solution in order to remove foreign substances, particularly dyes and metal ions, from the treatment solution, and e) precipitating terephthalic acid from the treatment solution, separating the precipitated terephthalic acid, and recovering a terephthalic-acid-including polyester raw material. In order to, within the scope of the mentioned method, enable the recovery of raw materials with an increased level of purity, it is proposed that filtering the treatment solution in step d) should at least comprise a filtration by an adsorbent filter medium.

A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.

A fabric for use in arc and flame protection, and a process for producing a fire resistant fabric are provided. The fabric is comprised of: more than 15% aramids; less than 50% modacrylic; less than 50% cellulose; and less than 15% nylon. The process comprises shredding recycled fire resistant garments into fibers; creating yarn from the shredded fibers; weaving the yarn into fabric; and knitting the yarn to produce new garments. The fabric may be used to produce fire-resistant garments worn by workers in many industries such as the oil and gas.

The present invention discloses a method and corresponding apparatus for separating lightweight materials from fabric pieces. The method comprises the steps of (a) introducing fabric pieces into a tumbling means having perforations for lightweight materials in the fabric pieces to be removed therethrough and coupled to a first source of negative pressure; (b) tumbling the fabric pieces in the tumbling means and simultaneously applying negative pressure from the first source of negative pressure to the tumbling means for removing lightweight particles detached from the tumbling fabric pieces from the tumbling means; (c) transporting the fabric pieces from the tumbling means to a top of a vertical separation chamber; and (d) applying forced air to the fabric pieces as the fabric pieces drop from the top to bottom of the vertical separation chamber by gravity for separating the lightweight materials from the fabric pieces, and simultaneously applying negative pressure from a second source of negative pressure to the vertical separation chamber to remove the lightweight materials separated from the fabric pieces from the vertical separation chamber; repeating this step until the fabric pieces are substantially cleared of any lightweight materials. The apparatus comprises a tumbling means and a vertical separation chamber.
