1240030 玖、發明說明： 【發明所屬之技術領域】 本發明是關於一種布料的加工方法，特別是指一種可 以提高撥水塗劑與布料間結合性之加工方法。 5 【先前技術】 一般市面所見到的布料大都係由天然纖維、人造纖維 或者兩種纖維混紡而成之紗線編織而成，其中，由天然纖 維或者天然纖維比例高於50%之紗線所織成之布料—般具 有較佳的吸濕性。為了讓此種親水性佳之布料具有撥水的 10 肖性’在已知的技藝中，有—種如圖1所示的加工方法， 該加工方法首先將布料含浸於一撥水塗劑（以下所稱的撥 水塗劑均具有撥水、撥油及去污的功效）浴21中，經過 一滾輪組22擠壓排出多餘水分，最後再把布料送到:烘 i5 乾器23烘乾，即可讓布料具有撥水、撥油及去污的特性。 15 此種已知的布料加工方法雖然可以讓布料兩側皆具 有撥水、撥油及去污的效果，然而在—般布㈣❹過程 中，採用純天然纖維或者天然纖維含量高之紗線來製成布 料的原因，通常是希望藉由天然纖維的親水性，讓布料具 〇 冑吸汗的功能，以提高穿著上的舒適性，但是此種吸水性 布料並不具有防水性，容易因為接觸水分（如慢跑者跑過 草地沾附露水）而吸收水分後，使衣料黏附人體上，造成 穿著上的不舒適性，故就布料使用的狀態，最好是讓朝向 人體皮膚的-侧具有吸濕的功能，而在遠離人體皮膚的另 一側面具有撥水的功能。再探討習知布料的撥水加工方 10 15 20 1240030 法，其主要係將撥水塗劑直接塗佈在布料上，但由於一般 親水性佳的布料滲透性很好，因此，在塗布撥水塗劑的過又 程中，撥水塗劑很快的會由塗佈的一側面滲透到未塗佈的 另一側面，而破壞另一側面的吸濕效果，導致穿著上的不 舒適。為了改善此-缺失，有的業者利用雙層組織針織的 方式，以吸濕加工的紗織一面；撥水紗織另一面，織造具 有面吸水、-面撥水效果的布料，惟此種作法只適合應 用在厚度較大之冬季布料上，無法運用在春夏季的布料 上，在使用的領域上受到很大的限制。 &此外，直接在布料上塗佈撥水塗劑雖然具有撥水的功 月匕’但疋一般由氟碳化合物為主體的撥水劑，因為糊劑包 覆作用的影響，無法和布料產生緊密的結合，因此，布料 在使用&時間後，撥水效果會因洗務而快速地消失，亦 即’以上述加工方法所處理之布料的撥水性不財久洗，在 設計上亦有待改進。 【發明内容】 个^之目的係在提供—種布料的單面具有撥 ，且撥水塗劑與布料間具有較佳結合性之加工方法 撥水:Γ之另一目的係在提供一種布料的雙面皆 =果，且撥水塗劑與布料間具有較佳結合性之加 本發明加1 ^ 效果之布料，所來製造—單面具有撥水 而节力工士述布料具有—加工面’以及-非加工面， 而5亥加工方法包含以下步驟：1240030 发明 Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for processing cloth, and more particularly to a method for improving the bonding between the water-repellent coating agent and the cloth. 5 [Previous technology] Most of the cloths seen in the market are woven from natural fibers, rayon or a blend of two types of fibers. Among them, natural fibers or yarns with a proportion of natural fibers higher than 50% are woven. Woven fabric-generally has better moisture absorption. In order to make this kind of hydrophilic fabric have water repellency, in the known technology, there is a processing method as shown in Figure 1. This processing method first impregnates the fabric with a water-repellent coating agent (hereinafter The so-called water-repellent coating agents have the functions of water-repellent, oil-repellent and decontamination) In the bath 21, a roller set 22 squeezes out excess water, and finally sends the fabric to: a drying i5 dryer 23 to dry, It can make the fabric have the characteristics of water repellency, oil repellency and decontamination. 15 Although this known fabric processing method can make the fabric have water-repellent, oil-repellent, and stain-removing effects on both sides of the fabric, in the general fabric process, pure natural fibers or yarns with high natural fiber content are used. The reason for fabric is usually to make the fabric have the function of absorbing sweat through the hydrophilicity of natural fibers to improve wearing comfort. However, this kind of water-absorbent fabric is not waterproof and is easy to contact with moisture. (Such as a jogger running across the grass with dew) and absorbing the moisture, causing the clothing to stick to the human body, causing discomfort in wearing. Therefore, it is best to let the side facing the human skin absorb moisture when the fabric is used. Function, while on the other side away from the human skin has a water repellent function. The 10 15 20 12 400 30 method of water repellent processing of the conventional cloth is mainly discussed. The main method is to directly apply the water repellent coating agent to the cloth. However, because the cloth with good hydrophilicity generally has good permeability, it is necessary to apply water repellent. During the course of the coating agent, the water-repellent coating agent will quickly penetrate from the coated side to the uncoated other side, thereby destroying the moisture absorption effect of the other side, causing discomfort in wearing. In order to improve this -deletion, some companies use double-layer knitting to weave one side with moisture-absorbing yarns; weave the other side with weaving yarns to weave fabrics with water-absorbing and water-repellent effects, but this method is only suitable It is applied to winter fabrics with a large thickness, and cannot be applied to spring and summer fabrics, and its application field is greatly restricted. & In addition, although the water-repellent coating agent is directly applied to the cloth, although it has the function of water-repellent, it is generally a water-repellent agent mainly composed of fluorocarbons. Because of the coating effect of the paste, it cannot be produced with the cloth. Tightly combined, therefore, after using & time, the water repellent effect will quickly disappear due to washing, that is, the water repellency of the fabric treated by the above processing method will not be washed for a long time, and it remains to be designed. Improve. [Summary of the invention] The purpose of each ^ is to provide a kind of fabric with a single side of the fabric, and the water-repellent coating agent and fabric have a better combination of processing methods of water repellent: Γ Another purpose is to provide a fabric Both sides are fruit, and the water-repellent coating agent and the cloth have a better combination. The cloth with the effect of the present invention plus 1 ^ is produced—one side has water repellency and the energy-saving engineer says that the cloth has—processed surface. 'And-non-machined surface, and the 5 Hai processing method includes the following steps:

The cloth u is woven from a variety of yarns, and these yarns are made of natural fibers such as cotton, wool, silk, 10 15 hemp, etc., or contain 50% The above-mentioned natural fiber is made of a blended fiber #. Since the yarn woven into the cloth Π contains a large amount of natural fibers with good hygroscopicity, the woven cloth has better hygroscopicity. The special adhesive coating 12 and the water-repellent coating 13 are sequentially bonded to the processing surface 111 of the cloth 11. With reference to FIG. 4 ′, the processing method of the present invention includes the following steps: Applying reactive acrylic paste · Applying a layer of reactive acrylic paste on the processing surface 111 of the cloth 11 to form the adhesion shown in FIG. 2 Coating 12, the above-mentioned reactive acrylic paste system comprises: an aqueous solution of 2% by weight of acrylic acid (Acrylate) and 98 to 99% by weight of water. A preferred acrylate is, for example, : Block isocyanate. According to the test results of the applicant, it is inferred that after the reactive acrylic paste coated by the present invention is applied, the acrylate will penetrate into the fiber to form a buried pile-like effect, and a substance forming a protective film is attached to the cloth. 11 的 加工 面 111。 11 processing surface 111. 2. The first pre-drying: Because the reactive paste of the present invention contains water, 1240030 In order to prevent the paste from penetrating into the raw surface 112 of the cloth Π, the present invention is coated with the reactive acrylic paste Perform a pre-drying step first. The above pre-drying step means that the hot air of 110 to 120 ° C is blown from the unprocessed surface 112 toward the processed surface ln, thereby preventing the paste from penetrating into the unprocessed surface 112 of the cloth 1. The pre-drying step can also use infrared drying. First drying for the first time · The drying operation is then carried out to dry / solidify the reactive acrylic paste, and the temperature for drying is generally controlled at 156 ° C. Fourth-person soaping • Wash away excess reactive acrylic paste with soaping agents. The soaping agents mentioned above are generally anionic surfactants, and non-ionic surfactants can also be used. 5. The first water wash: wash away the soaping agent used in the previous step. The first person to dry · Dry the moisture, the temperature is generally controlled at 120 ~ 130 ° C. 7. Application of reactive water repellent coating agent: A layer of reactive water repellent coating agent is applied on the processing surface lu of the cloth u to form the water repellent coating layer 13 shown in FIG. 2. The aforementioned water repellent coating agent contains the following ingredients : _ 4 ~ 8 parts by weight of water-repellent agent: selected from fluorocarbons, for example, a fluorocarbon compound manufactured by DuPont under the trade name “〇le〇ph〇b〇i77i3”; 1 part by weight of a thickener Specific examples: Compounds manufactured by DuPont under the trade name "A1 coprint PTF"; 1 part by weight of bridging agent: selected from blocked diisocyanates, specific examples: made by Fuying Jintex, brand name rabbit "^ ^ Jintexguard 1240030 FCN" isocyanates, 3 parts by weight of penetrant: is a kind of organic ethers, specifically for example ... made by Niwa Corporation, the product meaning is "π mouth name Texport BG" Organic ether; 5 parts by weight detergent, specifically, for example, made by DuPont Corporation, 5 compounds with a trade name of "〇-ZSR"; 1 part by weight of anti-yellowing agent, for example, citric acid; and the foregoing The total amount of the components is 100 parts by weight of water. 8. The second pre-drying. The processing conditions are the same as the first pre-drying, that is, the raw surface 112 of the cloth 11 is blown to the processing surface lu. 10 Nine, the third drying · Processing conditions are the same as the first drying. Tenth-Human soaping · Wash out the thickener in the reactive water repellent coating agent with soaping agent. X. Second water washing: Wash off the soap. 11. Fourth drying: The water remaining in the cloth n after washing is removed by 15 to complete the processing of the finished cloth product 1. In the aforementioned processing method of the present invention, after the steps of applying the reactive acrylic paste and the water-repellent coating agent, a pre-drying operation is performed immediately. The pre-drying step is to blow hot air from the unprocessed surface 112 to the processed surface 111. This step can further prevent the water-repellent coating agent and paste from quickly infiltrating the unprocessed surface 112 by the hygroscopicity of the fiber itself, thereby allowing the finished fabric 1 to have moisture absorption and water repellent effects. At the same time, in the present invention, the step of pre-coating the reactive acrylic paste before applying the water-repellent coating agent can make the acrylic components in the paste combine with the fibers in the same way as the buried pile, When a bridging agent containing the same composition and a water-repellent blade containing 1240030 groups of isocyanate-reactive groups are coated on the acrylic paste, the reactive-based component in the water-repellent agent can be reacted with the reactive acrylic. The isocyanate composition of the strength and bridging agent and the fiber hydroxyl or amine group produce better bonding. According to Shen Yanren's actual tests, the manufacturing method of the present invention can be used on fabrics with a weight of 150 ~ 200 W. After being washed 20 times, the water repellency of the finished product 1 of Maoming still has 4 levels. The oil effect is still 3 grades, and the de-pi effect is still 3 and grades. The above water repellency and oil repellency tests are measured according to the AATCC 118 method; the decontamination effect is measured according to the aatcc 13o method. Referring to FIG. 5, a second preferred embodiment of the processing method of the present invention is used to manufacture a finished fabric with water-repellent effect on both sides. The above processing method includes the following processing steps: 1. The money-absorbing type pressure: the acrylic tree ㈣ The composition is roughly the same as in the first embodiment. As long as there is more water in the acrylic resin for the purpose of pressure absorption, this step is to place a reactive acrylic aqueous solution in a container, and then press dip the cloth. In this aqueous solution, the reactive acrylic component in the resin described above will interact with the fibers in the cloth to produce a buried pile, and form the cohesive coating 12 shown in FIG. 2. -, Section-Blow Drying · W 150 ~ 160. . The first drying is performed on the pressure-absorbing acrylic paste. 3. Soap washing: Wash the excess acrylic resin in the cloth with soaping agent. 4. Washing: Wash the soaping agent used in soaping with clean water. V. Pressure-absorbing water-repellent coating agent: Use the water-repellent coating agent as in the first embodiment, and immerse the cloth in the water-repellent coating agent in a pressure-absorbing manner. 10 1240030 VI. Second drying ... Dry the fabric in the same way as the first drying. After drying, the finished fabric with water repellent, oil repellent and decontamination effects on both sides can be completed. The disaster relief material has the functions of water-repellent, oil-repellent, and decoupling on both sides. At the same time, the present invention first performs pressure-reactive acrylic resin before pressure-absorbing water-repellent coating. 15 In the step, the acrylic resin in the reactive acrylic resin has an adhesive force with the fibers of the cloth, and the isocyanate terminal group or the warp group in the reactive acrylic resin can repel water with the reactive type. The terminal groups in the coating agent generate bridging or take reaction. Therefore, in addition to the effects of water repellent and oil repellent decontamination on both sides of the fabric finished product of the processing method of the present invention, it also has better utility. The above are only the preferred embodiments of the present invention. If not, the scope of implementation of the present invention is not limited, that is, simple equivalent changes made according to the scope of the present invention and the contents of the description of the invention, and Modifications should still fall within the scope of the invention patent.
