毛巾克重与 GSM 指南
Towel Weight and GSM Guide
什么是 GSM？ / What is GSM?
GSM 是每平方米织物的质量，单位为克/平方米（g/m²）。单条克重是整条产品的质量，单位为克（g）；尺寸通常用厘米表示。三者相关，但不能混为一谈。
GSM means grams per square meter of fabric. Unit weight is the mass of one finished item in grams, while dimensions describe its size. These are related but distinct specifications.
计算方法 / Calculation
对于近似均匀、长方形的成品，估算公式：GSM ≈ 单条克重(g) ÷ [长度(m) × 宽度(m)]。反过来：单条克重(g) ≈ GSM × 长度(m) × 宽度(m)。
For an approximately uniform rectangular finished towel: GSM ≈ item weight (g) / [length (m) × width (m)]. Conversely, item weight (g) ≈ GSM × area (m²).
示例：70 × 140 cm、重量 420 g 的浴巾，面积为 0.70 × 1.40 = 0.98 m²，估算 GSM = 420 ÷ 0.98 ≈ 429 g/m²。该数据仅为演算示例，不代表维泰某款产品的实际规格。
Example: a 70 × 140 cm bath towel weighing 420 g has an area of 0.98 m², giving an approximate GSM of 429 g/m². This is an illustrative calculation, not a specification for any particular Weitai product.
为什么只是估算？ / Why is it approximate?
缎档、提花、包边、绣花、装饰部件、洗后缩水、含水率及称重条件，都可能影响单条重量与面密度的对应关系。对于工厂报价和工艺核算，不能简单使用成品克重倒推毛经、地经和纬纱的实际用纱量，应以完整工艺单、组织参数及损耗数据分别计算。
Borders, jacquard patterns, hems, embroidery, shrinkage, moisture and weighing conditions can affect the relationship between item weight and GSM. Manufacturing yarn consumption and costing require separate warp and weft calculations based on the production specification and loss allowances; they should not be inferred solely from finished-item weight.
询价需要提供什么？ / Information for a quotation
建议明确：货号或参考图片、用途、尺寸、目标克重或 GSM、纱线材质及纱支、织造组织、颜色、数量、包装和检测要求。认证状态、报价及交期以具体产品和双方确认为准。
Please provide a product reference, intended use, dimensions, target unit weight or GSM, yarn material and count, construction, colors, quantity, packaging and testing requirements. Certification, price and lead time must be confirmed for the specific order.
