Description

fabric structure

The present invention relates to a fabric structure, and in particular to a degradable fabric structure.

Generally speaking, the fabric structure (such as canvas) that was first applied to the sunshade or sunshade of advertisements or storefront buildings is usually woven from PE. The braided layer is not waterproof, so a coating layer must be coated on the surface to achieve waterproof function. Although it has the advantage of low specific gravity, the coating layer is not easy to adhere to the surface of the braided layer, and there is only a thin layer , and the softness of its own material is insufficient, when the fabric structure made of PE is bent or collided, the coating layer is easily damaged or peeled off at the fold, and the waterproof function will be lost at this time.

Then, as shown in Figures 1 and 2, a fabric structure 10 woven with PVC is produced accordingly, which is formed by gluing or hot-pressing a layer of PVC12 and 13 on the upper and lower surfaces of the fiber base cloth layer 11 in the middle. It has the characteristics of good tensile strength and excellent water resistance, so it is often used as waterproof sunshade and advertising canvas. However, PVC is the abbreviation of polyvinyl chloride, which is Polyvinylchloride in English. It is called "toxic plastic" by Greenpeace International, but because of its cheapness and convenient manufacture, it has become the second largest general-purpose plastic after PE. Widely exist around our lives, seriously threatening our environment and health.

Furthermore, PVC is the only chlorine-containing plastic among the five general-purpose plastics (PE, PVC, PP, PS, and ABS). Due to the chlorine content, the softness can be changed by adding plasticizers. In addition to plasticizers, the thermal stability of PVC is very poor. In order to avoid cracking of PVC products under the sun or high temperature, stabilizers must be added, usually heavy metals such as lead, cadmium, and zinc. Therefore, PVC is not just PVC, but also contains some plasticizers and stabilizers that are harmful to health and the environment; PVC itself that does not add anything at all is not poisonous, but it is also useless.

Therefore, the reason why Greenpeace International calls PVC "toxic plastic" does not refer to PVC itself without any additives, but it does not only refer to PVC products containing additives, but because of its entire life cycle, All stages from raw material mining, manufacturing, use, to disposal will cause harm to the environment and human health.

Furthermore, PVC is bright in color, corrosion-resistant, and durable, but its thermal stability and light resistance are poor. It begins to decompose hydrogen chloride when it is above 100°C or exposed to sunlight for a long time. Therefore, it is necessary to add stabilizers, plasticizers, anti- Some toxic auxiliary materials such as aging agents are used to enhance its heat resistance, toughness, ductility, etc. The density of pure PVC is 1.4g/cm3, and the density of PVC added with plasticizers is generally 1.15~2.00g/ ^cm3 ; however, these harmful additives and plasticizers in PVC may seep or gasify, interfere with biological endocrine, and affect Reproductive function can increase the risk of cancer, so some types of plasticizers have been listed as substances of high concern by EU countries and their use is completely banned. Furthermore, taking the United States as an example, 75% of plastic waste is finally disposed of in landfills, which is not conducive to the environment. Therefore, the fabric structure made of PVC has the above-mentioned problems, so there is still room for improvement.

The invention provides a fabric structure, which can achieve the purpose of environmental protection while solving the problem of difficult disposal.

Fig. 8 is a graph comparing the biodegradation rate of wood pulp viscose fiber and other materials according to some embodiments of the present invention. Please refer to Figure 8. The vertical axis is the biodegradation rate %, and the horizontal axis is the number of days. The biodegradation rate of polyester fiber after 180 days is only about 10%, and the biodegradation rate of polyester-cotton blended fabric is about 45%. Environmental standards. The biodegradation rate of wood pulp viscose fiber can exceed 75% in 45 days, and can exceed 90% in 180 days, and can finally achieve the goal of complete degradation, so it is much better than polyester fiber and polyester-cotton blended fabrics. . As for PVC, because it cannot be degraded, it is not included in the comparison of the coordinate chart. Accordingly, the present invention uses wood pulp viscose fiber as the fiber base cloth layer 20. Since the wood pulp viscose fiber has a dry strength (baked strength) exceeding 30.0 cN/tex and has good hygroscopicity, it is combined with water-based polyester. The use of acrylic fabric coating glue can make the fabric structure have characteristics such as good compatibility and strong mutual bonding force, so it can become a better product (such as becoming a very high-quality environmental protection printing advertising cloth), but the present invention does not limited to this.

In the present invention, since the wood pulp viscose fiber used in the fabric structure 60 fiber base cloth layer 20 has a high-density mesh 23 and tensile properties, the adhesive layer 30 and the adhesive layer 40 are made of water-based polyacrylate When the fabric coating adhesive is coated on the first surface 24 and the second surface 25 of the fiber base cloth layer 20 respectively, these film layers are non-toxic, odorless, tasteless milky white high crystalline polymers, which are currently the lightest varieties of plastics. One, the density is only 0.90-0.91g/cm ³ , which is about 60% of the density of PVC.
