The invention relates to recycling and more particularly to a closed loop recycling identification system for adding a tracer to a recyclable in a yarn spinning step so that it is possible to confirm a textile product as one made of the recyclable by identifying the tracer, and traceability system for entire process.
At present, most of used PET (polyethylene terephthalate) bottles, used clothes, waste textiles and other related products in the world, except some being recycled, are incinerated or land filled as waste. Carbon dioxide produced by the incineration has caused the earth's greenhouse effect and produces harmful substances that are harmful to health. Further, landfilling may discharge harmful substances to underground water and produce odor, thereby causing serious pollution problems to living and the environment. In recent years, many governments and private sectors have implemented recycling of used PET bottles. For example, in a known “recycling method and system thereof” discloses a method for converting used products to intermediate raw materials which can be used to manufacture products again, and a system for recycling using the method. The recycling consumes a small amount of energy. However, the patent is directed to a group, and each of joining upstream and downstream members do not have a control mechanism to control the quantity of each link except that the joining upstream and downstream members know each other. While the patent uses identifications to manage the recycling of products, the identification is not embedded in the product. There is no way to confirm whether a product is made of recyclables or not. Further, transaction price and bonus are disclosed by the patent and it is prone to transaction disputes. Thus, the need for improvement still exists.

The first flow 10 is applied to sources of waste materials to be recycled which do not includes a tracer. The first flow 10 comprises a step 11 of collecting polyester materials in which a waste recycling plant 110 recycles waste materials from the sources of waste materials to collect the polyester materials. The source of waste materials includes PET bottles which are pulverized by shredding, the pulverized plastics are further converted to polyester fibrous pellets; recycled used clothes and decorations which are cleaned and pulverized by shredding, and the pulverized clothes and decorations are processed to collect polyester fibers; used industrial and household items which are cleaned and pulverized by shredding, and the pulverized items are processed to collect polyester fibers; and used textiles or textile wastes which are pulverized by shredding and the pulverized textiles or wastes are processed to collect polyester fibers. The collected polyester fibers are converted to polyester pellets.
The first flow 10 further comprises a step 12 of spinning the collected polyester fibers as yarn. Through a spinning mill 120, the polyester fiber pellets are spun into long-spun yarn, or the long-spun yarn is cut into short-spun yarn as required. The spinning mill 120 can also spin recycled polyester fibers into short-spun yarn. A tracer 121 is added to the collected polyester fibers of the step 12. In detail, the tracer 121 of 1 wt % or less of the collected polyester fibers is added to the step 12 of spinning the collected polyester fibers so that the formed yarn can be identified whether they are products of the invention. The tracer 121 is fibrous materials of the yarn, fibers of different shapes of the yarn, or fibers of different colors of the yarn. Alternatively, silver ions or minerals are added to the yarn as the tracer 121. Still alternatively, fibers of different sectional shapes such as circle, triangle, W, M, 4-T, U, X, Y, Z, cross, double-cross, cup, snowman, pentagon, hollow cylinder, hollow cross, hollow Y or any of the above combinations thereof are added to the yarn as the tracer 121. Still alternatively, fibers having a color of red having green dyes is added to the yarn as the tracer 121. The short-spun yarns of different sources are 100% recycled polyester fibers and are used to manufacture textiles.
The first flow 10 further comprises a step 13 of weaving the yarn into fabric. In detail, a weaving factory 130 weaves the yarn having a tracer 121 into fabric.
The first flow 10 further comprises a step 14 of manufacturing the fabric into textile products. In detail, a textile manufacturer 140 manufactures the fabric having the tracer 121 into textile products.
The first flow 10 further comprises a step 15 of selling the textile products to exporters, dealers, or retailers.
The first flow 10 further comprises a step 16 of selling the textile products from the exporters, the dealers, or the retailers to general consumers.
The textile products made from the first flow 10 can be identified as ones made by the invention since it has the tracer 121.
The second flow 20 is related to the processing of waste materials having the tracer 121 and comprises a step 21 of cleaning. In detail, the waste recycling plant 110 cleans the collected waste materials having the tracer 121 and removes materials not having 100% polyester such as buckles, zippers, or the like from the clean waste materials. Additionally, sub-steps of killing microorganisms and bag packaging are included in the step 21.
The second flow 20 further comprises a step 22 of classifying the clean waste materials having the tracer 121 as ones having no more than 100% of polyester fibers and other materials or ones having 100% of polyester fibers. The second flow 20 further comprises a step 23 of pulverizing the classified waste materials into polyester fibers if the clean waste materials are classified as materials having no more than 100% of polyester fibers and other materials. Alternatively, the second flow 20 further comprises a step 24 of pulverizing the classified waste materials into polyester pellets if the clean waste materials are classified as 100% of polyester fibers. Additionally, color is added as an item of the classification.
The second flow 20 further comprises a step 25, as a subsequent step of step 23 or 24, of adding a new tracer 121 to a product of step 23 and spinning the product into long-spun yarn, or adding a new tracer 121 to a product of step 24 and spinning the product into short-spun yarn. The step 25 returns to the step 12 (i.e., the step 25 being a joining step). This completes a closed cycle which can be repeated.
Fabric and textile products made by the invention have a tracer which can be identified visually by microscope. Thus, a third party can identify a source of the waste materials which are used to manufacture the fabric and textile products of the invention by recycling. The products of the invention are manufactured from recycled waste materials in a closed cycle. As a result, waste is reduced, carbon emission is decreased, energy consumption is decreased, pollution is decreased, and manufacturing cost is decreased.

The invention has the following advantages and benefits in comparison with the conventional art: the closed loop recycling identification system 100 sets conditions for adding the tracer 121 in the cloud database 101 so that the waste recycling plant 110 may identify waste materials sent from the consumer ends 160 are made by the closed loop recycling identification system 100 of the invention by means of the identification. Further, it may monitor each producer (or consumer) of the manufacturing process based on batches or records. The sales ends 150 may identify a source of waste materials by means of an identification issued by the closed loop recycling identification system 100. Thus, manufacturing date and number of products of each production step can be controlled. As a result, a product having verified compositions is provided. The consumer ends 160 may generate a QR code by means of the closed loop recycling identification system 100 so that a consumer may be aware that whether a product is produced by recycled materials by scanning the QR code.
Conditions of the tracer 121 can set as one of any materials, fibers of different shapes, or fibers of different colors of the yarn. Alternatively, silver ions or minerals are added to the yarn as the tracer 121. Still alternatively, fibers of different sectional shapes such as circle, triangle, W, M, 4T, U, X, Y, Z, cross, double-cross, cup, snowman, pentagon, hollow cylinder, hollow cross, hollow Y or any of the above combinations thereof are added to the yarn as the tracer 121. Still alternatively, fibers having a color of red having green dyes is added to the yarn as the tracer 121. The waste recycling plant 110 may identify a source of waste materials by means of the closed loop recycling identification system 100. The source of waste materials means a source of waste materials without any tracer. After a unit certified by the closed loop recycling identification system 100 has identified the source of waste materials, the tracer 121 can be added to the closed loop recycling identification system 100. As a result, the production capacity is greatly increased and more waste materials are recycled for further use.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
