Description

Synthetic yarn structure made of recycled PVB modified materials

The new type of synthetic yarn structure particularly refers to a synthetic yarn structure made of recycled PVB (polyvinyl butyral, hereinafter referred to as PVB) modified materials.

Artificial fabrics such as chair surfaces, placemats, parasols, indoor office chairs or computer chairs, pet beds and other artificial fabrics of outdoor furniture need to have the requirements of tensile, abrasion, waterproof and weather resistance; the past method is to use PET (Polyester plastic) PVC polyvinyl chloride material is attached to the fiber yarn, and the combination of the two can form a synthetic fiber yarn with PVC-coated PET fiber yarn (hereinafter referred to as PVC-coated PET synthetic yarn). Welcome in the market; but in the past 20 years, research has found that due to poor stability of PVC, PVC products cracking under the sun or high temperature must also add stabilizers, usually heavy metals such as lead, cadmium, and zinc, and also contain some health and environmental effects. Harmful plasticizers and stabilizers; therefore, PVC coated PET synthetic yarns are gradually eliminated by the market.

With the improvement of environmental protection awareness, humans have also developed alternatives to PVC-coated PET synthetic yarns. For example, TPU (thermoplastic polyurethane) is used to coat PET synthetic yarns. TPU can decompose in about 5-10 years in the natural environment; however, TPU-coated PET The problem with synthetic yarn is that TPU material is easily hydrolyzed. It can be understood that after a period of use, the artificial fiber fabric made of TPU coated PET synthetic yarn will decompose and cannot be stored for a long time.

How to overcome the above-mentioned problems is a topic that the relevant industry players are actively solving.

The main purpose of this new model is to provide a synthetic yarn structure made of recycled PVB modified material. The recycled PVB modified material is used to coat PET (polyester plastic, hereinafter referred to as PET) filaments. The advantage is that it does not contain plastic The chemical agent complies with EU REACH regulations.

The secondary purpose of this new model is to provide a synthetic yarn structure made of recycled PVB modified materials. The manufactured synthetic yarn structure is environmentally friendly, non-toxic, decomposable, and has good mechanical strength, tensile strength, abrasion resistance, water resistance and long weather resistance. .

The secondary purpose of this new model is to provide a synthetic yarn structure made of recycled PVB modified materials, to extract PVB modified materials from discarded automobile glass or discarded laminated glass, and then attach the PVB modified materials to PET On the fiber, and the used synthetic yarn structure can be recycled again, to achieve the advantages of green economy and sustainable operation and protect the earth.

For this reason, the structure of the present invention includes: at least one PET yarn body made of PET, the outer surface of the PET yarn body is covered with a PVB layer attached with recycled PVB modified material to form a synthetic yarn structure .

In the embodiment of the present invention, the PVB layer to which the aforementioned recycled PVB modified material is attached is extracted from discarded automobile glass or discarded laminated glass.

In an embodiment of the present invention, the aforementioned PET yarn body is wound on a first spool, and a free end of the PET yarn body is disposed on a second spool, between the first spool and the second spool. A PVB covering device is arranged between the bobbins, and the PVB covering device attaches the PVB layer attached to the recovered PVB modified material to the PET yarn body.

In the embodiment of the present invention, the synthetic yarn structural fiber Denny number is 1800 Danny and 2900 Danny.

Based on the above description, the features and effects of the present invention are briefly described as follows:

1. This new model can replace the previous mainstream PVC-coated PET synthetic yarn, and improve the finished product made of synthetic yarn structure. It is not only tensile, abrasion-resistant, waterproof, weather-resistant and not easy to be hydrolyzed, and can extend the life of the product.

2. The new model does not contain plasticizers, and the materials are non-toxic and comply with EU REACH regulations.

3. The PVB modified material is extracted from the discarded automobile glass or the discarded laminated glass, and then the PVB modified material is attached to the PET fiber yarn, and the used synthetic yarn structure can be recycled again to achieve a green economy The advantages of sustainable management and care of the earth.

4. Through the new synthetic yarn structure, related products such as chair surface of outdoor furniture, placemat, parasol, indoor office chair or computer chair cloth, pet bed and other related products can be manufactured

Figure 1 is a perspective view of the structure of the present invention.

Fig. 2 is a cross-sectional view of the partial structure of Fig. 1A-A.

Figure 3 is a schematic view of the manufacturing of the present invention.

As shown in Figure 1, Figure 2, and Figure 3, the synthetic yarn structure 100 made of recycled PVB modified material of the present invention is connected to a first spool 10 with multiple PET yarn main bodies A, a first The second bobbin 20 is used to collect the PET yarn main body A. A PVB covering device 30 is provided between the first bobbin 10 and the second bobbin 20. The aforementioned PET yarn main body A passes through the PVB covering device 30, Let the outer surface of the PET yarn body be covered with a PVB layer 40 to form a synthetic yarn structure 100, and the second The spool 20 is wound on the second spool 20. When the PET yarn main body A on the first spool 10 is used up, the synthetic yarn structure 100 on the second spool 20 can be taken out and penetrate the synthetic yarn The thread structure 100 weaves a rayon cloth structure.

Among them, the synthetic yarn structure 100 fiber deniers are 1800 deniers and 2900 deniers.

Compared with PVC-coated PET synthetic yarn, the new structure is thinner and lighter, so that the finished product can achieve a lightweight effect.

In addition, the material used in the PVB coating device 30 is to extract the PVB layer 40 from discarded automobile glass or discarded laminated glass, so even if it is discarded automotive glass or discarded laminated glass, useful materials can still be extracted , To achieve the goal of sustainable operation in a green economy.

In summary, the new structure has never been seen in books or publicly used, and it is in compliance with the requirements of a new patent application. I sincerely ask Jun Bureau to approve the patent as soon as possible. I really pray.

If you need to clarify, the above are the technical principles immediately used in the implementation of the new model. If the changes made in accordance with the concept of the new model do not exceed the spirit covered by the specification and drawings, All should be within the scope of this new model, and should be combined with Chen Ming.
