酒店布草的质量鉴别涉及多个方面，包括材质、工艺、使用性能等。以下是综合多个来源的实用鉴别方法：

　　The quality identification of hotel linens involves multiple aspects, including material, craftsmanship, and performance. The following are practical identification methods that integrate multiple sources:

　　1. 观察外观与洁净度

　　1. Observe the appearance and cleanliness

　　白度与洁净度：优质布草应干净、亮白，无污渍或发黄现象。若床单、被罩或枕套发黄，可能因洗涤不彻底或水质不合格。

　　Whiteness and Cleanliness: High quality linen should be clean, shiny white, without stains or yellowing. If the bed sheets, duvet covers, or pillowcases turn yellow, it may be due to incomplete washing or poor water quality.

　　平整度：检查床单、被罩是否平整，褶皱过多可能因压平机调整不当或员工操作失误，影响美观和舒适度。

　　Flatness: Check whether the bed sheets and duvet covers are flat. Excessive wrinkles may affect the appearance and comfort due to improper adjustment of the flattening machine or employee operation errors.

　　2. 手感与材质判断

　　2. Texture and material judgment

　　柔软度：纯棉布草应手感柔软、透气性好。若发硬或发涩，可能因洗涤时碱性残留（PH值超标）或漂洗不彻底。

　　Softness: Pure cotton linen should have a soft touch and good breathability. If it becomes hard or astringent, it may be due to alkaline residue (excessive pH value) during washing or incomplete rinsing.

　　材质鉴别：

　　Material identification:

　　棉与涤纶区分：纯棉布草表面绒毛较多，揉搓后易留褶痕且恢复慢；涤纶或混纺面料则不易起皱，手感更光滑。

　　Difference between cotton and polyester: Pure cotton cloth has more fluff on the surface, which is prone to leaving creases and slow recovery after rubbing; Polyester or blended fabrics are less prone to wrinkling and have a smoother hand feel.

　　燃烧法：棉纤维燃烧迅速，有烧纸味，灰烬呈灰色粉末；涤纶燃烧时熔融滴落，有黑烟和刺鼻气味。

　　Burning method: Cotton fibers burn rapidly, with a burning paper smell, and the ash is a gray powder; Polyester melts and drips during combustion, producing black smoke and a pungent odor.

　　3. 吸水性测试（适用于毛巾类）

　　3. Water absorption test (applicable to towels)

　　滴水法：水滴在毛巾上，渗透时间小于3秒为合格，小于1秒则吸水性优异。

　　Drip method: Water droplets on towels with a penetration time of less than 3 seconds are considered qualified, and less than 1 second indicates excellent water absorption.

　　沉降法：将样品放入水中，完全浸湿时间越短，吸水性越好。

　　Settlement method: Place the sample in water, and the shorter the complete soaking time, the better the water absorption.

　　4. 工艺与耐用性检查

　　4. Process and durability inspection

　　经纬密度与克重：高密度面料（如T250、T300）更耐用。可通过称重法检测平方米克重，防止商家以细纱支冒充粗纱支。

　　Longitude and latitude density and weight: High density fabrics (such as T250, T300) are more durable. The square meter weight can be detected by weighing method to prevent merchants from impersonating fine yarn as coarse yarn.

　　强力测试：撕拉强力和单拉强力反映面料抗破损能力，优质布草应无明显棉结或异纤。

　　Strength test: Tear strength and single pull strength reflect the fabric's ability to resist damage, and high-quality linen should have no obvious cotton knots or foreign fibers.

　　做工细节：走线整齐、无脱线，边角处理精细，尺寸符合标准。

　　Craftsmanship details: neat wiring, no loose lines, fine edge treatment, and dimensions that meet standards.

　　5. 特殊污渍与洗涤效果

　　5. Special stains and washing effect

　　污渍残留：检查是否有未洗净的血渍、果汁渍等，优质布草应经严格洗涤和消毒。

　　Stain residue: Check for unwashed blood stains, juice stains, etc. High quality linen should be strictly washed and disinfected.

　　色牢度与缩水率：多次洗涤后不应褪色或严重缩水。全棉布草缩水率一般不超过5%，预缩处理后可降至3.5%。

　　Color fastness and shrinkage rate: It should not fade or shrink severely after multiple washes. The shrinkage rate of cotton linen generally does not exceed 5%, and can be reduced to 3.5% after pre shrinking treatment.

　　6. 品牌与认证

　　6. Brand and Certification

　　选择知名品牌（如康乃馨、斯得福）或通过正规渠道采购，确保符合行业标准（如消防、卫生要求）。

　　Choose well-known brands (such as Carnation and Sidefu) or purchase through formal channels to ensure compliance with industry standards (such as fire safety and hygiene requirements).

　　总结

　　summary

　　综合运用感官观察、物理测试和工艺检查，可全面评估布草质量。建议采购时索取检测报告，并定期抽样送检，确保长期使用性能。

　　By integrating sensory observation, physical testing, and process inspection, the quality of linen can be comprehensively evaluated. It is recommended to request testing reports during procurement and regularly sample for testing to ensure long-term performance.
