回收片狀體之改製方法Recycling method for recycling sheet

種回收片狀體之改製方法，特別是一種將回收片狀體改製形成編織紗或織物的方法。A method for reforming a recovered sheet, in particular, a method for reforming a recovered sheet to form a woven yarn or fabric.

高分子片狀材料經常是許多產品的半成品或零件，例如包裝材料、顯示器、民生用品等，都會用到各種不同顏色、厚度、材質、結構等等特徵的片狀材料。為了達到特定的要求，片狀材料在製造或加工過程依據不同用途而使該片狀材料通常無法回收再利用。舉例而言，淋膜複材、複層貼合片狀材料、表面含金屬或其他材質鍍膜之高分子片狀材料等等，這些配合加工與使用需求的片狀材料因為表面或者局部包含不同材料，使其難以透過物理或者化學方法分離可再利用的高分子材料，整體的片狀材料通常僅能燃燒銷燬，造成非常嚴重的污染與浪費問題。Polymer sheet materials are often semi-finished products or parts of many products, such as packaging materials, displays, and people's livelihoods. They use sheet materials of various colors, thicknesses, materials, structures, and the like. In order to meet specific requirements, the sheet material is typically not recyclable in the manufacturing or processing process depending on the application. For example, a laminated composite material, a laminated laminated sheet material, a polymer sheet material coated with a metal or other material on the surface, and the like, which are combined with processing and use requirements, have different materials because of surface or partial. It makes it difficult to separate reusable polymer materials by physical or chemical methods. The overall sheet material is usually only burned and destroyed, causing very serious pollution and waste problems.

為了解決現有的片狀材料廢料燃燒、丟棄與掩埋所造成的環境污染，部分板片材料無法回收再製成為塑膠原料等諸多技術問題，本發明提出一種可以轉製該些板片材料形成紗線製品、編織物等，解決現有技術僅能將片狀材料燃燒銷燬、丟棄與掩埋所造成的環境污染問題，不僅解決環境污染問題，更進一步達到材料再生利用、再設計、再製造、再修復、再生、減量、生態復原等的技術效果。In order to solve the environmental pollution caused by the burning, discarding and burying of the waste material of the sheet material, some of the sheet materials cannot be recycled and then made into a plastic material, and the like, and the present invention proposes that the sheet material can be converted into a yarn product. Knitting materials, etc., solve the problem of environmental pollution caused by burning, destroying, discarding and burying sheet materials in the prior art, not only solving environmental pollution problems, but also further realizing material recycling, redesign, remanufacturing, re-repairing, regeneration, Technical effects such as reduction and ecological restoration.

請參考圖1，其為一種回收片狀體之改製方法，其步驟包含：Please refer to FIG. 1 , which is a method for reforming a recovered sheet body, and the steps thereof include:

步驟1.切割一種以上材料特徵的片狀材料，形成複數個條狀物：Step 1. Cutting a sheet of material characterized by more than one material to form a plurality of strips:

前述步驟1所述之該片狀材料至少局部包含高分子材料，例如高分子片材、高分子薄膜、多層複合膜、淋膜紙等，該高分子材料之材質例如聚酯(PET)、三醋酸(TAC)、聚丙烯(PP)、聚四氟乙烯(PTFE)、聚氯乙烯(PVC)、聚乙烯(PE)、聚甲基丙烯酸甲酯(PMMA)、PA聚醯胺(PA)、聚氨基甲酸酯(PU)等。該片狀材料之厚度不限定，例如為0.1~100cm左右。步驟1所述的切割寬度依據該片狀材料之材質特性、厚度以及用途而有所不同，較佳為裁切該片狀材料之寬度大於該片狀材料的厚度。The sheet material described in the above step 1 at least partially comprises a polymer material, such as a polymer sheet, a polymer film, a multilayer composite film, a coated paper, etc., and the material of the polymer material is, for example, polyester (PET), three Acetic acid (TAC), polypropylene (PP), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyethylene (PE), polymethyl methacrylate (PMMA), PA polyamine (PA), Polyurethane (PU) and the like. The thickness of the sheet material is not limited and is, for example, about 0.1 to 100 cm. The cutting width described in the step 1 varies depending on the material properties, thickness and use of the sheet material, and it is preferred that the width of the sheet material is larger than the thickness of the sheet material.

步驟2. 取兩個以上待編條，其中至少一個該待編條10為該條狀物，將兩個以上的該待編條沿著長度方向以包覆、包繞（如圖3）、絞繞、撚合或合撚(如圖2)而形成一紗條20：Step 2. Take more than two to-be-striped strips, at least one of which is to be stripped 10 as the strip, and wrap two or more of the strips to be wrapped along the length direction (Fig. 3), Winding, twisting or merging (as in Figure 2) to form a sliver 20:

前述步驟2所選的兩個以上的該待編條10中，至少其中之一係選用該片狀材料所裁切產生的該條狀物，所選的該條狀物可包含不同的材料特徵，該材料特徵包含材質、顏色、透光度、硬度、層狀結構及厚度等。At least one of the two or more of the to-be-strips 10 selected in the foregoing step 2 is selected from the strip material, and the selected strip may include different material characteristics.

步驟2參與絞繞、撚合或合撚等之其他該待編條10可為其他材質之紗、線、金屬絲、塑膠條、織物等等，如此，可將回收的回收片狀體參與其他不同效能的材料而混合撚製成不同效能的紗線。例如，可將材質為塑膠之片狀材料裁切成條狀之後，與具有高含水效能的纖維（如天然、植物纖維）共同撚合，利用該片狀材料之結構強度及天然、植物纖維的高含水率、高涵養份能力，撚合生成同時具備高結構強度、高含水率的紗製品，不僅可使無法回收的塑膠材料可以再生利用，更同時創造出具備產業效益的新產品，如編織成為種植花草樹木之花器或植生袋等。Step 2: The other to-be-striped strips 10 which are involved in twisting, twisting or merging may be yarns, wires, wires, plastic strips, fabrics, etc. of other materials, so that the recovered recovered flakes can be involved in other Different performance materials are mixed and made into yarns with different performances. For example, after cutting a sheet of material made of plastic into strips, it can be combined with fibers having high water-yield properties (such as natural and vegetable fibers), and the structural strength of the sheet material and the natural and plant fibers are utilized. High water content, high nutrient capacity, and yarn products with high structural strength and high water content can not only recycle plastic materials that cannot be recycled, but also create new products with industrial benefits, such as weaving. Become a flower plant or planting bag for planting flowers and trees.

前述步驟2所述的該淋膜紙為包含一基底紙材料表面披覆一高分子薄膜。該多層複合膜為多層高分子薄膜構造，或者為包含金屬鍍層或無機材料鍍層之高分子片狀材料。The coated paper according to the above step 2 is characterized in that a surface of a base paper material is coated with a polymer film. The multilayer composite film is a multilayer polymer film structure or a polymer sheet material including a metal plating layer or an inorganic material plating layer.

步驟3. 取複數個待編條10，編織形成一織物30，如圖4a~4b。Step 3. Take a plurality of strips 10 to be woven and form a fabric 30, as shown in Figures 4a-4b.

進一步地，於步驟2完成後，可施以一熱延伸/定型步驟，係將該紗條20置於一延伸溫度或一定型溫度下，將該紗條20予以延伸或定型，使該紗條20不易因為使用過程而分散與斷裂，延長使用壽命。該延伸溫度/定型溫度可依據該紗條20的材料特性而選定，例如該紗條20中高分子材料的相變化或軟化溫度，使該紗條20於熱延伸/定型步驟過程，使已經完成包覆；包繞、絞繞、撚合的紗條20予以部分熔合、延伸或定型。Further, after the completion of the step 2, a heat stretching/setting step may be applied, and the sliver 20 is placed at an extension temperature or a certain type temperature, and the sliver 20 is extended or shaped to make the sliver. 20 It is not easy to disperse and break due to the use process, and prolong the service life. The extension temperature/setting temperature can be selected according to the material properties of the sliver 20, for example, the phase change or softening temperature of the polymer material in the sliver 20, so that the sliver 20 is subjected to a heat stretching/setting step to complete the package. The wrapped, twisted, twisted sliver 20 is partially fused, extended or shaped.

在應用方面，本發明的紗條20可用於一般民生用品，例如提帶、繩、包、袋、墊、鞋、簾等；或者，使用包含金屬鍍層或光學鍍層的該條狀物，於編織之後形成織物可具備例如紫外線、紅外線遮蔽等光學暨隔熱效果。In terms of applications, the sliver 20 of the present invention can be used for general consumer goods such as straps, ropes, bags, bags, pads, shoes, curtains, etc.; or, using a strip comprising a metal coating or an optical coating, for weaving The formed fabric can then be provided with optical and thermal insulation effects such as ultraviolet rays and infrared shielding.
