在酒店的運營中，桌椅套作為提升用餐與住宿體驗的細節元素，其品質至關重要。而色牢度，宛如隱藏在其中的 “試金石”，默默檢驗著桌椅套的質量。優質的色牢度能確保桌椅套持久如新，反之則可能帶來諸多困擾。那么，酒店桌椅套的色牢度測試有著怎樣的標準呢？這背后藏著保障酒店形象與顧客滿意度的關鍵密碼。

　　In the operation of hotels, the quality of table and chair sets is crucial as a detail element to enhance the dining and accommodation experience. And color fastness, like a hidden "touchstone", silently tests the quality of table and chair covers. High quality color fastness can ensure that desk and chair covers last as good as new, otherwise it may bring many troubles. So, what are the standards for color fastness testing of hotel desk and chair covers? Behind this lies the key password to ensure the hotel's image and customer satisfaction.

　　耐摩擦色牢度：日常 “摩擦” 的考驗

　　Color fastness to friction: a test of daily "friction"

　　酒店桌椅套在日常使用中，頻繁與顧客衣物、餐具等發生摩擦。耐摩擦色牢度測試便是模擬這一情景。將標準的白色摩擦布固定在摩擦測試儀的摩擦頭上，在規定壓力下，對桌椅套試樣進行干摩擦與濕摩擦測試。干摩擦時，白色摩擦布以一定次數、速度在桌椅套表面往復摩擦；濕摩擦則需提前將白色摩擦布浸濕至規定含水率。測試完成后，通過專業的沾色灰色樣卡，對比摩擦布上沾染桌椅套顏色的程度進行評級，等級從 1 到 5 級，5 級最佳，表示幾乎無掉色，1 級最差，掉色嚴重。一般酒店桌椅套的干摩擦色牢度要求達到 4 級及以上，濕摩擦色牢度達到 3 級及以上，以確保在長期使用中，桌椅套不因摩擦而明顯掉色，維持美觀。

　　Hotel table and chairs frequently come into contact with customers' clothing, tableware, and other items during daily use. The test for color fastness to friction simulates this scenario. Fix the standard white friction cloth on the friction head of the friction tester, and conduct dry and wet friction tests on the table and chair cover samples under the specified pressure. During dry friction, the white friction cloth rubs back and forth on the surface of the table and chair cover at a certain frequency and speed; Wet friction requires wetting the white friction cloth to the specified moisture content in advance. After the test is completed, a professional colored gray sample card is used to compare the degree of color staining on the friction cloth for the table and chair covers. The rating ranges from 1 to 5, with 5 being the best, indicating almost no color fading, and 1 being the worst, indicating severe color fading. The dry friction color fastness of general hotel table and chair covers is required to reach level 4 or above, and the wet friction color fastness is required to reach level 3 or above, to ensure that the table and chair covers do not significantly fade due to friction and maintain their appearance during long-term use.

　　耐水洗色牢度：頻繁清潔的挑戰

　　Color fastness to washing: a challenge of frequent cleaning

　　酒店為保持環境整潔，桌椅套需定期清洗。耐水洗色牢度測試就是模擬這一清潔過程。把桌椅套試樣與規定的貼襯織物縫合在一起，放入皂洗色牢度試驗機中，加入特定濃度的洗滌劑溶液，在一定溫度（如 40℃左右）下洗滌規定時間（如 30 分鐘）。洗滌結束后，取出試樣和貼襯織物，清洗、干燥。同樣依據灰色樣卡，評定桌椅套試樣的變色程度以及貼襯織物的沾色情況。對于酒店桌椅套，耐水洗色牢度通常要求變色達到 4 級及以上，沾色達到 3 - 4 級及以上，保證多次水洗后，桌椅套顏色依然穩定，不出現褪色、串色現象，避免影響酒店整體格調。

　　To maintain a clean environment, the hotel requires regular cleaning of tables and chairs. The color fastness test to washing simulates this cleaning process. Sew the table and chair cover samples together with the specified lining fabric, place them in a soap washing color fastness testing machine, add a specific concentration of detergent solution, and wash at a certain temperature (such as around 40 ℃) for a specified time (such as 30 minutes). After washing, take out the sample and lining fabric, clean and dry them. Based on the gray sample card, evaluate the degree of discoloration of the table and chair cover samples and the staining of the lining fabric. For hotel table and chair covers, the color fastness to water washing usually requires a color change of level 4 or above, and a staining of level 3-4 or above, to ensure that the color of the table and chair covers remains stable after multiple washes, without fading or color mixing, and to avoid affecting the overall style of the hotel.

　　耐汗漬色牢度：人體接觸的考量

　　Color fastness to sweat stains: considerations for human contact

　　酒店中，顧客用餐或休息時，桌椅套難免會接觸到汗液。耐汗漬色牢度測試需要模擬人體汗液環境，分別配制酸性汗液（pH 值約 5.5）與堿性汗液（pH 值約 8.0）。將桌椅套試樣完全浸入兩種汗液中，在 37℃的烘箱中放置 4 小時，模擬人體出汗時的溫度與時間。取出試樣自然干燥后，使用灰色樣卡評估其在酸性和堿性汗液作用下的變色情況。酒店桌椅套的耐汗漬色牢度要求在酸 / 堿汗漬條件下均達到 3 - 4 級及以上，防止因汗液侵蝕導致顏色變化，為顧客提供良好體驗。

　　In hotels, when customers dine or rest, desk and chair covers are inevitably exposed to sweat. The color fastness test to sweat stains requires simulating the human sweat environment, preparing acidic sweat (pH value about 5.5) and alkaline sweat (pH value about 8.0) separately. Immerse the table and chair cover samples completely into two types of sweat and place them in a 37 ℃ oven for 4 hours to simulate the temperature and time of human sweating. After natural drying of the sample, evaluate its discoloration under acidic and alkaline sweat using a gray sample card. The color fastness to sweat stains of hotel table and chair covers is required to reach level 3-4 or above under acidic/alkaline sweat conditions, to prevent color changes caused by sweat erosion and provide customers with a good experience.

　　耐光色牢度：光照環境的應對

　　Color fastness to light: response to light environment

　　酒店內的自然采光或人造燈光，也會對桌椅套顏色產生影響。耐光色牢度測試使用氙燈老化儀模擬自然光照條件，將桌椅套試樣與藍色羊毛標樣一同放入儀器，在規定的輻照度（如 1.1W/m?）、黑板溫度（如 50℃左右）下連續光照一定時間（如 24 小時甚至更長，視情況而定）。測試結束后，對比試樣與藍色羊毛標樣的褪色程度進行評級，評級從 1 到 8 級，8 級最好。室內使用的酒店桌椅套耐光色牢度一般要求達到 4 級及以上，若用于戶外區域，如酒店庭院桌椅套，則需達到 5 級及以上，確保在長期光照下，桌椅套顏色不發生明顯褪色，始終保持鮮艷。

　　The natural or artificial lighting in the hotel can also affect the color of the table and chairs. The light fastness test uses a xenon lamp aging apparatus to simulate natural lighting conditions. The table and chair cover samples are placed together with the blue wool standard sample in the instrument at a specified irradiance (such as 1.1W/m)? ）Continuous exposure to light for a certain period of time (such as 24 hours or even longer, depending on the situation) at a blackboard temperature (such as around 50 ℃). After the test is completed, the fading degree of the comparison sample and the blue wool standard sample is rated from 1 to 8, with 8 being the best. The color fastness of hotel table and chair covers used indoors generally requires a level of 4 or above. If used in outdoor areas such as hotel courtyard table and chair covers, it needs to reach a level of 5 or above to ensure that the color of the table and chair covers does not fade significantly under long-term light exposure and remains bright at all times.
