Description

ation] John O'Mahoney 109420-AU-PA TEXTILE STRUCTURE BACKGROUND Technical Field

[0001] The disclosure relates to a textile structure, and in ular, to a degradable textile structure.

Description of Related Art In general, the textile structures (e.g. a canvas) used in the past for advertising or sun blocking or as canopies for shops and buildings are usually woven by polyethylene (PE). They are single-color woven layers or woven layers with stripes of colors woven by PE warp s and weft threads. These woven layers themselves are not waterproof, so a tion film layer has to be coated on their surfaces for a waterproof function. The lamination film layer has an advantage of low specific gravity, however, it is not easy for the lamination film layer to attach on the surfaces of the woven layers, the lamination film layer is thin and the material itself lacks sufficient softness, therefore, when the textile structures woven by PE are bent or bumped, the lamination film layer tends to be damaged or peeled off at a crease and thus lose its waterproof function.

Hence, a textile structure 10 woven by PVC as shown in and has d as a solution to the problem above. The textile structure 10 is ed of a PVC layer 12 and a PVC layer 13 glued to or hot pressed on the upper and the lower surfaces of a fiber-based layer 11 in the middle. The textile structure 10 exhibits a good tensile strength and a good waterproof on, so it is usually adopted as a waterproof, sun blocking, or advertising canvas. However, PVC, short for nylchloride, is regarded as "toxic plastic" by the Greenpeace. Despite its toxicity, the production of PVC had made it the second only to PE among the most widely used plastics since it is cheap and easy to manufacture. PVC is [Annotation] John O'Mahoney 109420-AU-PA everywhere in our daily lives and causes serious damage to the environment and our health.

Moreover, among the five most widely used cs (PE, PVC, PP, PS, ABS), PVC is the only one containing chlorine. Since PVC contains chlorine, the softness can be d by adding a plasticizer. Besides, PVC exhibits terrible thermal stability. Apart from a plasticizer, a stabilizer has to be added into PVC to prevent PVC products from pyrolysis when exposed to the sun or high temperature. A stabilizer is usually heavy metal such as lead, m, or zinc. Therefore, PVC is not as simple as itself. It contains a cizer and a stabilizer which are harmful to the environment and our health. Although PVC itself without any additives is non-toxic, it is useless.

[0005] Accordingly, the term "toxic plastic" used by the Greenpeace does not refer to PVC itself without any additives nor merely the PVC products containing the ves. It refers to the whole life cycle of the PVC products, of which each phase starting from raw material tion, manufacturing, use to disposal is harmful to the environment and our health.

Furthermore, PVC is resistant to corrosions and has bright colors, high hardness, and great durability, while it exhibits worse thermal stability and photostability. Exposed to sunlight for a long time or being at 100˚C, PVC would be decomposed and, consequently, hydrogen chloride would be emitted. Therefore, when manufacturing plastics, it is necessary to add some toxic auxiliary materials such as a stabilizer, a plasticizer, and an antiager to strengthen the heat resistance, ess, extensibility, and so on. A density of pure PVC is 1.4 g/cm3, and a density of PVC with additives such as a plasticizer is 1.15 to 2.00 g/cm3. The harmful additives and cizer in PVC may effuse or gasify and thus disturb the endocrine system and the reproductive system of an organism and pose a risk of developing a cancer. As a result, some types of cizers have been listed as substances of high concern by the EU countries and the use of these substances are completely banned. In addition, in the US, for example, 75% of plastic waste ends up in landfills, which is l to the environment.

[0031] First, a e structure 60 of the embodiment is, for example, an inkjet painting advertising canvas; however, the disclosure is not limited thereto. The textile structure may be any other suitable textile structures. Referring to , , and in the embodiment, the textile structure 60 includes a based layer 20 and a glue layer (alternatively a glue layer 30 or a glue layer 40). The based layer 20 has meshes 23 and includes fiber of which basic composition is cellulose (C6H10O5)n. The glue layer (alternatively the glue layer 30 or the glue layer 40) penetrates into the meshes 23. Accordingly, the fiber-based layer 20 of the embodiment has meshes and includes fiber of which basic composition is cellulose. Since ose is natural fiber, cellulose exhibits a greater ation rate and biological compatibility during a disposal process, and as a result, may serve as an eco-friendly solution to a textile structure disposal issue.

[Annotation] John O'Mahoney 109420-AU-PA In some embodiments, the fiber-based layer 20 may be a mesh-shaped woven fabric woven by warp threads 21 and weft threads 22 of wood pulp viscose fiber of which basic composition is cellulose. Hence, the fiber-based layer 20 has the meshes 23, as shown in and . Here, the wood pulp viscose fiber is manufactured by following process.

The l fiber (wood fiber or cotton linter) is adopted as a raw material, then, soluble ose xanthate is ctured through procedures such as alkalization, aging, and sulfonation and is dissolved in a diluted lye solution to manufacture viscose. Then, viscose goes through wet spinning to manufacture the wood pulp e fiber. Furthermore, a baked strength of wood pulp viscose fiber is over 30.0cN/tex, and wood pulp viscose fiber exhibits good hygroscopicity. A re regain of wood pulp viscose fiber at a standard atmospheric condition is approximately 13%. Wood pulp viscose fiber expands apparently after moisture absorption, and its diameter may increase by approximately 50%; however, the disclosure is not d thereto. In other embodiments, the fiber-based layer 20 may be manufactured with cotton yarn of which basic ition is cellulose. In addition, natural fiber exhibits a good degradation effect in a disposal process and in a natural aquatic environment. ore, natural fiber exhibits favorable biological compatibility and benefits of environmental protection.

In some ments, a basic weight of the fiber-based layer 20 is approximately between 170 gsm and 200 gsm, and its thickness is approximately between 0.2 mm and 0.8 mm, such that the fiber-based layer 20 has the meshes 23 with a high density and has a high tensile property. For example, the thickness of the fiber-based layer 20 may be 0.3 mm; however, the disclosure is not limited thereto.

In some embodiments, an angle of the intersection of the warp threads 21 and the weft threads 22 is 90 s, and a width of the warp threads 21 and the weft s 22 is approximately between 0.2 mm and 1 mm. The disclosure is not limited thereto.

[Annotation] John O'Mahoney 109420-AU-PA In some embodiments, a shape of the meshes 23 may be square or other suitable shapes, and a density of the meshes 23 is 34 to 50 strands per square inch warpwise and 35 to 50 strands per square inch weftwise. In addition, each of the meshes 23 may have a substantially identical size. The disclosure is not limited thereto.

[0036] In some embodiments, the fiber-based layer 20 has a first surface 24, and a second surface 25 opposite to the first surface 24. The glue layer 30 is d on the first surface 24 of the fiber-based layer 20. The glue layer 40 is located on the second surface 25 of the fiber-based layer 20. Furthermore, the glue layer 30 and the glue layer 40 are attached on the fiber-based layer 20 and are partially absorbed by the fiber-based layer 20 to penetrate into the meshes 23. Therefore, the glue layer 30 and the glue layer 40 may partially cover the meshes 23; however, the disclosure is not limited o.

In some embodiments, the glue layer 30 and the glue layer 40 may be respectively coated on the first surface 24 and the second surface 25 of the fiber-based layer 20 to allow the glue layer 30 and the glue layer 40 to penetrate into the meshes 23. For example, a liquid of an adhesive material may be coated on the fiber-based layer 20 with a scraping knife. The disclosure is not limited thereto. In other ments, the glue layer 30 and the glue layer 40 may also form on the fiber-based layer 20 through a lamination film or in other suitable manners.

In some embodiments, a material of the glue layer 30 and the glue layer 40 may be an aqueous polyacrylate (PA) textile g adhesive which is waterproof and fireproof; however, the sure is not limited thereto. In an ative embodiment, the material of the glue layer 30 and the glue layer 40 may be materials such as PU, PP, or PE. Here, the s polyacrylate textile g adhesive may be composed of the following. Based on 100 wt% of a total content of all the composition, the ition includes 45 wt% to 65 wt% of aqueous polyacrylate in a range of 200 g/m2 to 230g /m2 as a main material, 20 wt% to 35 wt% of fire [Annotation] John O'Mahoney 109420-AU-PA ant slurry, 4 wt% to 12 wt% of brightener, 2 wt% to 8wt% of water, and 0.4 wt% to 3 wt% of auxiliary agent. In this way, a basic weight of the e structure 60 is approximately between 370 g/m2 and 430 g/m2; however, the disclosure is not limited thereto.

Furthermore, the aqueous polyacrylate textile coating adhesive has multiple functions such as a waterproof function and a fire ing function. The aqueous rylate textile coating layer adhesive is copolymerized generally by a hard component (e.g. polymethyl acrylate) and a soft component (e.g. polybutyl acrylate). Main monomers of a polyacrylate coating layer are acrylic acid, methyl te, ethyl acrylate, butyl acrylate, and the like. In order to facilitate its waterproof function, acrylamide and acrylonitrile may be added if ary. A peroxide (e.g. ium persulfate) is usually adopted as a polymerization initiator. Therefore, the aqueous polyacrylate textile coating adhesive has the following functions such as good light and climate fastness, being less subject to yellowing, good transparency and compatibility, being favorable for color coating t manufacturing, good launderability, good adhesion, and being cost-effective. The disclosure is not limited thereto.

However, the disclosure is not limited thereto.

In some embodiments, the brightener includes an optical ening agent and may be composed of an optical brightening agent, a dispersant, and water. The optical brightening agent may be compounds of triazine-stilbenes, and the dispersant may be compounds of sodium methylene thalene sulfonate. Hence, whiteness of the textile structure 60 which is manufactured is increased by using an optical effect of the optical brightening agent. However, [Annotation] John O'Mahoney 109420-AU-PA the disclosure is not limited thereto.

In some embodiments, the auxiliary agent may include and be composed of one of an iolet stabilizer, an antioxidant, or an antistatic agent or any ations thereof.

However, the disclosure is not limited thereto.

[0043] In some embodiments, a thickness of the glue layer 30 and a ess of the glue layer 40 are imately between 0.2 mm and 0.8 mm. For example, the thickness of the glue layer 30 and the thickness of the glue layer 40 may be 0.3 mm; however, the disclosure is not limited thereto.

In some embodiments, the textile structure 60 further es a g 50 disposed on a surface of the glue layer (e.g. the glue layer 40) which is located above the meshes 23. The coating 50 includes an acrylic resin material (exhibiting a property of water absorption). The disclosure is not limited thereto. In an ative embodiment, the material of the glue layer 30 and the glue layer 40 may be materials such as PU, PP, or PE. In addition, the coating 50 may exhibit a blotting property. r, the disclosure is not limited thereto.

[0045] In some embodiments, the coating 50 may be coated on the surface of the glue layer 40. For example, a liquid of a coating material may be coated on the glue layer 40 with a scraping knife. The disclosure is not limited thereto. In other embodiments, the coating 50 may also form on the glue layer 40 through a lamination film or in other suitable s.

In some embodiments, a thickness of the coating 50 is approximately between 0.01 mm and 0.15 mm. For example, the thickness of the coating 50 may be 0.02 mm, and poster paint of digital inkjet painting may be ed on an upper e 51 of the coating 50. However, the disclosure is not limited thereto.

In some embodiments, a concave-convex microstructure of the surface of the coating 50 is based on a material property of the textile structure 60; however, the disclosure is not limited thereto. ation] John O'Mahoney 109420-AU-PA Note that the reference numerals of the elements and a part of the description in the embodiments above are used in the embodiments below in which the same or similar elements are denoted with the same reference numerals. The description of the same technological features will be omitted. With regard to the omitted ption, the embodiments above may be referred to, and it will not be repeated in the embodiments below. is a schematic cross-sectional diagram of a textile structure according to some embodiments of the disclosure. is a schematic diagram illustrating an application of a textile structure according to some embodiments of the disclosure. ing to and the textile structure 60 of the ment further includes a light blocking layer 80 disposed on the surface of the glue layer 30. The disclosure is not limited thereto. In other embodiments, the light blocking layer 80 may be disposed on the surface of the glue layer 40 (not shown). Furthermore, the light ng layer 80 may be disposed only on the surface of the glue layer 30, disposed only on the surface of the glue layer 40, or simultaneously disposed on both of the surfaces of the glue layer 30 and the glue layer 40.

[0050] In some embodiments, the light ng layer 80 may be coated on the surface of the glue layer (the glue layer 30 and/or the glue layer 40). For example, a liquid of a coating material may be coated on the glue layer (the glue layer 30 and/or the glue layer 40) with a scraping knife. The disclosure is not limited thereto. In other embodiments, the light blocking layer 80 may also form on the glue layer (the glue layer 30 and/or the glue layer 40) through a tion film or in other suitable manners.

In addition, the embodiment may further include an ink 70 ed on the textile structure 60, as shown in and Due to the blotting on of the coating 50 of the textile ure 60, it is not necessary to apply an extra clear coat or protection layer to the coating 50 after the ink 70 is inkjet painted on the coating 50. The visual effect and quality after inkjet painting are enhanced so as to increase an economic value of a product. However, ation] John O'Mahoney -AU-PA the disclosure is not limited o.

In some embodiments, a size of the textile structure 60 is greater than a size of the ink 70 so that the textile structure 60 may serve as a r of the ink 70; however, the disclosure is not limited o.

[0053] is a coordinate chart illustrating a comparison between the biodegradation rates of wood pulp viscose fiber and other degradable materials according to some embodiments of the sure. Referring to the al axis represents the biodegradation rate (%), and the horizontal axis represents the number of days. The biodegradation rate of polyester fiber over 180 days is only approximately 10%, and the radation rate of blend fabric of polyester staple fiber is approximately 45%, which do not conform to the standard of environmental protection. The biodegradation rate of wood pulp viscose fiber may be over 75% over 45 days, over 90% over 180 days, and, ultimately may be completely degraded.

Accordingly, wood pulp viscose fiber is much more favorable than polyester fiber and blend fabric of polyester staple fiber. PVC is not included in the coordinate chart for comparison since PVC is unable to be degraded. ingly, wood pulp viscose fiber is adopted as the fiber-based layer 20 in the disclosure. Since the baked strength of wood pulp viscose fiber is over 30.0cN/tex, and wood pulp viscose fiber exhibits great hygroscopicity, wood pulp viscose fiber accompanied by the aqueous polyacrylate textile coating adhesive may be used so that a textile structure may exhibit properties such as good compatibility and strong mutual binding force. Therefore, the textile structure may serve as a favorable product (e.g. serve as a good inkjet painting advertising canvas which is eco-friendly). The disclosure is not limited thereto.

In the disclosure, the wood pulp viscose fiber adopted by the fiber-based layer 20 of the textile structure 60 has the meshes 23 with a high density and has a high tensile property, and the glue layer 30 and the glue layer 40 made from the aqueous polyacrylate textile coating adhesive are coated respectively on the first surface 24 and the second surface 25 of the fiber-based layer [Annotation] John O'Mahoney 109420-AU-PA . The layers are milky white highly-crystallized polymers which are non-toxic, odorless, and tasteless. They are made from one of the lightest types of plastics with a density of only 0.90 to 0.91 g/cm3, which is around 60% of a density of PVC. Among plastics, polyacrylate exhibits the best heat ance and has a heat distortion temperature of 80˚C to 100˚C, and also exhibits good stress cracking resistance and long bending e life. rmore, the coating 50 is mainly composed of acrylic resin and may have a blotting function when used at a proper proportion with polyacrylate. Accordingly, the textile structure 60 of the disclosure may be a composite structure of a fireproof, roof, and ng g; however, the disclosure is not limited thereto.

[0055] In addition, since the textile ure 60 does not include PVC and is non-toxic, the textile structure 60 is particularly suitable for interior and exterior advertising and interior decoration. The textile structure 60 also conforms to the use of the medical standard.

Furthermore, compared with products which are currently commercially available, a weight of the textile structure 60 is reduced by 35% so the textile structure 60 is light and soft. The textile structure 60 is easy and convenient to install or disassemble and easy to remove.

Besides, since the e structure 60 exhibits good assembling structure strength and may be processed with a predetermined molding e, a width (W) of the e structure 60 may be customized based on a customer's need. The width (W) may reach a maximum of 5.0 m. In this way, the textile structure 60 may be inkjet painted flexibly based on a need of a practical design. Therefore, the textile structure 60 may be more applicable and selective.

The wood pulp viscose fiber of the disclosure is certified by the STANDARD 100 by OEKO-TEX® to use the OEKO-TEX® label with an OEKO-TEX STANDARD 100 test report SH004 .1 (of the textile ure 60). The report reads as follows: According to the product class I categorized by the STANDARD 100 BY OEKO-TEX® , a test result of the ts in the appendix 4 indicates that the goods above conform to the standard of the latest [Annotation] John O'Mahoney 109420-AU-PA textile products for babies and the Annex XVII of the current EU REACH (including the restrictions of use of azo dye, nickel, and so on). Meanwhile, the goods above also conform to the total lead content limits of products for children in the Consumer Product Safety ement Act (CPSIA) of the US. The certified company has made the declaration that conformity of an object to the specified requirements is attested according to ISO17050 1, ensuring that the OEKO- TEX® label is only applied to the goods conforming to the test sample.

The declaration undergoes a review and verification.

In ance with the procedures of ISO10993-10:2010, the test result of skin irritation test of the test sample extract conforms to the requirements.

[0067] Accordingly, the test reports above attest that the e structure 60 of the disclosure conforms to the use of medical rd.

The textile structure 60 of the disclosure exhibits cold hardiness at minus 40˚C without adding any additives. The textile structure 60 passes the standard test for use at low temperature (ASTM D2136-2002).

[0069] In summary of the above, the fiber-based layer of the disclosure has meshes and [Annotation] John O'Mahoney 109420-AU-PA includes fiber of which basic composition is cellulose. Since cellulose is natural fiber, cellulose exhibits a greater degradation rate and biological ibility during a disposal process, and as a result, may serve as an iendly solution to a textile structure disposal issue. Furthermore, the textile structure of the disclosure exhibits favorable inkjet painting effect as an advertising canvas. Compared with the advertising canvas currently commercially available, the weight of the textile structure of the disclosure may be reduced by nearly a half and softer and more convenient to use. It is also fast and simple to l and remove the textile structure of the disclosure. er, the material of the textile structure of the disclosure is light and has a compact size, which may effectively reduce the shipping cost. In addition, in the textile structure of the disclosure, compared with PVC adopted by a conventional advertising canvas, the tion of wood pulp viscose fiber is easier and more energy-efficient. In st, PVC products are typically -intensive products. PVC production consumes more energy and cost in both of the calcium carbide method and the ethylene method, which is against the current global trend of energy saving, low carbon emission, recycling, and g. Furthermore, the disposal process of the eco-friendly inkjet painting advertising canvas made from wood pulp viscose fiber also conforms to the requirement of environmental tion. In addition, the textile structure of the disclosure may be easily crushed and ed and transformed into other products, such as outer packaging, flower pots, inner lining in gs, and so on. The gas generated after burning the textile structure is unlikely to cause air pollution, and it does not generate other toxic substances which pollute soil and water when it ends up in landfills for decomposition. Therefore, the textile structure may be an eco-friendly solution.
