In addition, in an embodiment of the present invention, the plastic optical molding material is a plastic material suitable for manufacturing an optical lens, but the present invention is not limited thereto.
It is worth mentioning that the plastic optical molding material may be, for example, a recycled plastic optical molding material. In more detail, the recycled plastic optical molding material can be, for example, an unqualified product, rim charge, offcut, or any discarded molded product of plastic optical molding material, which is generated in the production process of the raw material of the plastic optical molding material.

For example, the selection of the solvent is within the scope of the present invention as long as the solvent can dissolve the plastic optical molding material and at the same time can increase the compatibility and dispersion uniformity between the plastic optical molding material and the polyurethane resin.
In step S120, a polyurethane resin (polyurethane) is mixed with the polymer solution by stirring to form a paste (also called paste or paste).
In more detail, in order to allow the paste material to be more easily processed in the subsequent process step (as in step S130), the viscosity of the paste material is preferably formulated to be between 1,000 centipoise (cP) and 4,000 cP, and more preferably between 1500 cP and 3,000 cP. The viscosity of the paste material may be adjusted by, for example, adjusting a mixing ratio between the polyurethane resin and the polymer solution, or by adding an appropriate amount of a thickener, which is not limited in the present invention.

The material of the silicon-containing additive may be selected from one of the above materials; or a combination of two or more selected from the above-mentioned material types, and the present invention is not limited thereto. For example, the silicon-containing additive may be selected from the group consisting of polydimethylsiloxane, which enhances the surface planarity of the film, and silicon dioxide, which enhances the anti-stick properties of the film. Furthermore, regardless of the material type of the silicon-containing additive, the weight percentage of the silicon-containing additive in the finally-formed functional fabric is preferably in the range of 0.01 wt% to 5 wt%. In an embodiment of the present invention, in order to increase the ultraviolet resistance of the finally formed functional fabric, the method for manufacturing a functional fabric may further include (step S130): and mixing an ultraviolet absorbent into the paste material, so that the functional fabric contains the ultraviolet absorbent after being formed.

The material type of the ultraviolet absorber is particularly suitable for being added to a polymer mixture of a polyurethane resin mixed plastic optical molding material. That is, the ultraviolet absorbent has good compatibility and dispersibility with the polymer mixture, so that the functional fabric has good ultraviolet resistance. If other types of ultraviolet absorbers are used, the functional fabric may not be able to provide good ultraviolet resistance.
In an embodiment of the present invention, in order to increase the antibacterial ability of the finally formed functional fabric, the method for manufacturing a functional fabric may further include (step S130): and mixing an antibacterial additive into the pasty material, so that the functional fabric contains the antibacterial additive after being formed.
The weight percentage of the antimicrobial additive in the finally formed functional fabric is preferably in the range of 0.2 wt% to 8.0 wt%. The antimicrobial additive is an inorganic substance such as metal ions having antimicrobial properties and a composite of the inorganic substance and an inorganic carrier, and examples of the antimicrobial additive include: silver ion antibacterial agent, zinc ion antibacterial agent …, and the like. Whereby the functional fabric can have an antibacterial activity value of not less than 2.0 (according to FTTS-FA-027, AATCC-100, JIS-L1902, ASTM-E2149, or ISO-20743 antibacterial textile validation specifications).
In step S140, the paste material is coated on a carrier, so that the paste material is formed into a film material. In more detail, the paste-like material may be applied to the support, for example, by doctor blade, spray coating, or roller coating. Further, the paste material is preferably applied to the support in an amount of 15 to 60 grams (preferably 15 to 50 grams) of the paste material per square meter of the support, and the support is preferably at least one selected from paper and cloth.
It should be noted that, since the film-like material is formed by applying a paste-like material onto a support, the composition of the film-like material is the same as that of the paste-like material. More specifically, the film-like material comprises plastic optical molding material, polyurethane resin, and solvent (and optionally silicon-containing additive, anti-UV additive, or antibacterial additive).
In addition, in the finally formed functional fabric, the sum of the weight percentages of the above components (including the urethane resin matrix, the plastic optical molding material, and other additives such as silicon-containing additives, ultraviolet absorbers, and antibacterial additives) is 100 wt%.
Preferably, the embodiment further includes a defoaming step before the step of coating the paste material on the carrier, but the invention is not limited thereto. And the defoaming treatment step is to perform defoaming treatment on the pasty material by using a vacuum defoaming machine or a defoaming agent so as to remove bubbles in the pasty material. Therefore, the waterproof and moisture permeable performance or other physicochemical properties of the functional cloth can be prevented from being affected by the bubbles, and the product yield of the functional cloth can be improved.

Test method of degree of water repellency (JIS L1092): the water repellency of the functional fabric (nonporous film) obtained by the dry treatment in this example was measured according to the high water pressure method (JIS L1092). The main use of the high water pressure method is to test the water resistance of the fabric against water penetration under hydrostatic pressure. The preparation step of the test piece comprises the following steps: cutting a functional cloth to obtain three rectangular test pieces (length is 15 cm multiplied by width is 15 cm) with specific sizes; and, snatch eachThree points in the sheet specimen were tested (e.g., left, center, and right). The test strip testing step comprises: filling a test water tank of a hydraulic press with normal-temperature distilled water; horizontally placing a test piece in the test water tank so that the test piece is contacted with distilled water and the processing surface of the test piece faces upwards (it is necessary to confirm that no air exists between the test piece and the test water tank); starting a chuck descending button of the hydraulic press to fix the test piece on the test water tank; the water pressure of the hydraulic press is controlled at 1 kg/cm/min 2 Or 10,000mm-H 2 The speed of O rises; when three water drops (or one water drop larger than 0.5 cm) appear on the processing surface of the test piece, immediately pressing a stop button of the hydraulic press and reading data; and, after the test is completed, zeroing the hydraulic press and performing the next round of testing.

The main purpose of the potassium acetate method is to test the degree of penetration of water vapor through the cloth. The preparation step of the test piece comprises the following steps: a functional cloth is cut to obtain three circular test pieces (about 5.6 cm in diameter) with specific sizes. The test strip testing step comprises: adding three hundred grams of an absorbent (potassium acetate) to one hundred grams of water to form an absorbent solution; standing the moisture absorbent solution for a predetermined time (about 8 to 12 hours); pouring the moisture absorbent solution into a moisture permeable cup so that two thirds of the accommodating space of the moisture permeable cup is filled with the moisture absorbent; preparing a moisture permeability measurement auxiliary film, wherein the moisture permeability measurement auxiliary film may be, for example, a Polytetrafluoroethylene (PTFE) film, and has a porosity of 80% and a thickness of 25 μm; fixing the auxiliary film for measuring moisture permeability on the moisture permeable cup; fixing the test piece on a support so that an outer surface (such as a non-coating surface) of the test piece faces inwards and an inner surface (such as a coating surface) of the test piece faces outwards; placing the support in a constant-temperature water tank (with water at 23 + -1 deg.C) in an inverted manner; fixing the test piece in waterA position 10 mm deep and left for 15 minutes; and measuring the mass change (mg/min) of the test piece within 15 minutes, thereby calculating the moisture permeability (g/m) of the test piece 2 Day).

a functional cloth (a non-porous film) is subjected to a yield phenomenon; continuing to apply a stress to the functional fabric. At this time, strain hardening (or work hardening) occurs. The tensile strength of the functional fabric is improved along with the improvement of the external stress. When the applied stress reaches the highest point, the stress at that point is the maximum tensile strength (UTS) of the functional fabric. As shown in the following equation, the maximum tensile strength (σ UTS) can be defined as:
wherein, P max The load on the functional fabric at maximum tensile strength, A 0 Is the original sectional area of the functional cloth. It is worth mentioning that for brittle materials, maximum tensile strength is an important mechanical property; for ductile materials, however, the maximum tensile strength value is not commonly used in industrial design because the material is plastically deformed significantly before this value is reached.
The phenol yellowing test (phenolic yellowing) was performed according to ISO 105-X18. Test samples: warp direction 10cm and weft direction 3 cm. The original sample: warp direction 10cm and weft direction 5 cm. The test device includes: test paper, yellowing cloth, glass sheet and PE film.
