在酒店的運(yùn)營(yíng)中，桌椅套作為提升用餐與住宿體驗(yàn)的細(xì)節(jié)元素，其品質(zhì)至關(guān)重要。而色牢度，宛如隱藏在其中的 “試金石”，默默檢驗(yàn)著桌椅套的質(zhì)量。優(yōu)質(zhì)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(cè)試有著怎樣的標(biāo)準(zhǔn)呢？這背后藏著保障酒店形象與顧客滿意度的關(guān)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(yàn)

　　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(fā)生摩擦。耐摩擦色牢度測(cè)試便是模擬這一情景。將標(biāo)準(zhǔn)的白色摩擦布固定在摩擦測(cè)試儀的摩擦頭上，在規(guī)定壓力下，對(duì)桌椅套試樣進(jìn)行干摩擦與濕摩擦測(cè)試。干摩擦?xí)r，白色摩擦布以一定次數(shù)、速度在桌椅套表面往復(fù)摩擦；濕摩擦則需提前將白色摩擦布浸濕至規(guī)定含水率。測(cè)試完成后，通過專業(yè)的沾色灰色樣卡，對(duì)比摩擦布上沾染桌椅套顏色的程度進(jìn)行評(píng)級(jí)，等級(jí)從 1 到 5 級(jí)，5 級(jí)最佳，表示幾乎無掉色，1 級(jí)最差，掉色嚴(yán)重。一般酒店桌椅套的干摩擦色牢度要求達(dá)到 4 級(jí)及以上，濕摩擦色牢度達(dá)到 3 級(jí)及以上，以確保在長(zhǎng)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(zhàn)

　　Color fastness to washing: a challenge of frequent cleaning

　　酒店為保持環(huán)境整潔，桌椅套需定期清洗。耐水洗色牢度測(cè)試就是模擬這一清潔過程。把桌椅套試樣與規(guī)定的貼襯織物縫合在一起，放入皂洗色牢度試驗(yàn)機(jī)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(guī)定時(shí)間（如 30 分鐘）。洗滌結(jié)束后，取出試樣和貼襯織物，清洗、干燥。同樣依據(jù)灰色樣卡，評(píng)定桌椅套試樣的變色程度以及貼襯織物的沾色情況。對(duì)于酒店桌椅套，耐水洗色牢度通常要求變色達(dá)到 4 級(jí)及以上，沾色達(dá)到 3 - 4 級(jí)及以上，保證多次水洗后，桌椅套顏色依然穩(wěn)定，不出現(xiàn)褪色、串色現(xiàn)象，避免影響酒店整體格調(diào)。

　　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?jié)n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(shí)，桌椅套難免會(huì)接觸到汗液。耐汗?jié)n色牢度測(cè)試需要模擬人體汗液環(huán)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(shí)，模擬人體出汗時(shí)的溫度與時(shí)間。取出試樣自然干燥后，使用灰色樣卡評(píng)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?jié)n色牢度要求在酸 / 堿汗?jié)n條件下均達(dá)到 3 - 4 級(jí)及以上，防止因汗液侵蝕導(dǎo)致顏色變化，為顧客提供良好體驗(yàn)。

　　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(huán)境的應(yīng)對(duì)

　　Color fastness to light: response to light environment

　　酒店內(nèi)的自然采光或人造燈光，也會(huì)對(duì)桌椅套顏色產(chǎn)生影響。耐光色牢度測(cè)試使用氙燈老化儀模擬自然光照條件，將桌椅套試樣與藍(lán)色羊毛標(biāo)樣一同放入儀器，在規(guī)定的輻照度（如 1.1W/m?）、黑板溫度（如 50℃左右）下連續(xù)光照一定時(shí)間（如 24 小時(shí)甚至更長(zhǎng)，視情況而定）。測(cè)試結(jié)束后，對(duì)比試樣與藍(lán)色羊毛標(biāo)樣的褪色程度進(jìn)行評(píng)級(jí)，評(píng)級(jí)從 1 到 8 級(jí)，8 級(jí)最好。室內(nèi)使用的酒店桌椅套耐光色牢度一般要求達(dá)到 4 級(jí)及以上，若用于戶外區(qū)域，如酒店庭院桌椅套，則需達(dá)到 5 級(jí)及以上，確保在長(zhǎng)期光照下，桌椅套顏色不發(fā)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.
