纱支、密度、克重、门幅：家纺行话到底在说什么
家纺采购里最容易出问题的，不是价格谈不拢，而是双方说的不是同一件事。行话在自己人之间是效率，对外行就是雾。
下面把最常被误读的几个参数逐个拆开。
一、纱支：40 支到底是什么
「40 支」在家纺里通常就等于 40×40——经纬纱支相同，所以只报一个数，是个简称，不是另一个规格。
只有经纱和纬纱不一样时才分开写，比如 21×21、21×32、40×60、60×80。看到「×」，说明经纬不同支。
最容易踩的坑：支数只表示纱的粗细，不直接等于品质高低。同样标 100 支，用什么棉花、怎么织、后整理怎么做，成品能差出一大截。把「支数高＝好」当成选购标准，是消费者最常被营销带偏的地方。
二、密度：12868 怎么读
行业里常写成 12868 这种连写形式，读法是 128×68，单位是「根/英寸」——即经向 128 根、纬向 68 根。
密度和支数要一起看才有意义：同样支数下密度高的更紧密、更厚实，但也不是越高越好，还要看织法和手感定位。
行业现实：密度虚报是这个行业的通病。而且要注意——检测报告只能证明送检的那一块样布，证明不了大货和样品一致。所以数据的可信度必须分级标注，而不是一句「有报告」就算数。
三、克重：面料有多重，决定它有多厚
克重的单位是 g/m²（每平方米多少克）。同样是全棉，克重从 100 出头到 200 多都有，手感、垂感、保暖性完全不同。买面料如果只谈「全棉」，不谈克重，等于没谈。
四、门幅：240 门幅是几米
门幅就是布有多宽。行业里习惯按米数简称：
| 行业俗称 | 实际门幅 |
|---|---|
| 1.5 门幅 | 150 cm |
| 1.6 门幅 | 160 cm |
| 2.35 门幅 | 235 cm |
| 240 门幅 | 240 cm |
床品面料的门幅直接决定裁剪利用率。同样一床四件套，门幅差 20cm，用料和损耗都不一样——所以门幅是报价单上必须写清的项。
五、计价单位：按米还是按公斤，这是钱的问题
面料有的按米卖、有的按公斤卖，这一点必须写清楚。同样叫「全棉汗布」，一家报 15 元/米、另一家报 25 元/公斤，不看单位根本没法比。
一般来说，克重稳定的常规面料按米谈更直观；克重波动大或者本身厚重（如绒类）的，按公斤更常见。
六、梭织和针织：先分大类，再谈组织
面料先分梭织和针织两大类，然后才是具体组织。因为组织选项随织造方式变——针织里出不了「斜纹」，梭织里也谈不到「汗布」。
- 针织常见：汗布、罗纹、卫衣布等
- 梭织常见：平纹、斜纹、缎纹（贡缎）、提花等
七、印染方式：活性印染和涂料印染不是一回事
两者成本、手感、环保性、色牢度都不同：
- 活性印染：染料和纤维发生化学反应结合，手感较软、色牢度较好、更环保，成本更高
- 涂料印染：颜料靠粘合剂附着在表面，工艺简单、成本低，但手感偏硬、耐洗性相对弱
报价差一截的时候，先问是哪种印染，比直接砍价有用。
八、几个容易搞混的叫法
- 被壳 / 被芯：同一个东西的不同叫法，不要当成两样产品去比对
- 花型不是定价变量，底布才是：同一个花型印在不同底布上，成本可以差很多。先问底布（材质+克重+门幅），再谈花型
- A 类 / 无甲醛这类安全声明，需要有质检报告支撑，不是印染的默认属性
九、一张表说清「问什么才有用」
| 你要买 | 必须问清的参数 |
|---|---|
| 面料 | 材质成分与比例、纱支（或经纬）、密度、克重、门幅、织法、印染方式、计价单位（米/公斤）、起订量、交期 |
| 成品套件 | 材质、纱支、密度、件数、规格尺寸、工艺（素色/印花/磨毛）、填充物、包装 |
| 被芯类 | 面料材质、填充材质与克重、被重、尺寸、工艺 |
| 库存货（额外） | 品质等级、已知瑕疵（实拍）、存放时长、批次是否一致 |

The hardest part of buying home-textile fabric isn't the price negotiation — it's that the two sides aren't talking about the same thing. Trade jargon is efficient among insiders and opaque to everyone else.
Here are the parameters most often misread.
1. Yarn count: what "40s" means
In home textiles, "40s" usually equals 40×40 — warp and weft the same count, so only one number is quoted. It's shorthand, not a different spec.
Warp and weft are written separately only when they differ: 21×21, 21×32, 40×60, 60×80. If you see a "×", the two directions differ.
The trap: count describes yarn fineness — it does not directly equal quality. Two fabrics both labelled 100s can differ enormously depending on cotton, weave and finishing. "Higher count = better" is the single most common marketing distortion.
2. Density: how to read 12868
Trade shorthand like 12868 reads as 128×68, in threads per inch — 128 warp, 68 weft.
Density only means something alongside count: at the same count, higher density is tighter and heavier, but higher isn't automatically better — it depends on weave and the intended hand feel.
Industry reality: inflated density figures are common. And note — a test report only proves the sample that was submitted, not that bulk production matches it. Data credibility has to be graded, not reduced to "we have a report."
3. GSM: how heavy the fabric is
Measured in g/m². All-cotton fabric can range from just over 100 to 250+, and the hand, drape and warmth differ completely. Quoting "all cotton" without GSM is quoting nothing.
4. Width: what "240 width" means
Width is how wide the roll is. The trade abbreviates by metre figures:
| Trade shorthand | Actual width |
|---|---|
| 1.5 width | 150 cm |
| 1.6 width | 160 cm |
| 2.35 width | 235 cm |
| 240 width | 240 cm |
Width directly determines cutting efficiency. On the same bedding set, a 20 cm difference in width changes fabric consumption and waste — which is why width belongs on every quotation.
5. Pricing unit: per metre or per kilogram changes the money
Some fabrics are sold by the metre, others by weight — and this must be stated. A quote of ¥15/m against ¥25/kg is uncomparable until you look at the unit.
Broadly: stable, regular fabrics are easier to discuss per metre; heavy or weight-variable fabrics (fleece, for instance) are often per kilogram.
6. Woven vs knit: the category comes first
Fabrics split first into woven and knit, then into construction — because the available options depend on the construction method. You won't find "twill" in a knit, or "jersey" in a woven.
- Knit: jersey, rib, fleece-backed, etc.
- Woven: plain, twill, sateen, jacquard, etc.
7. Dyeing: reactive and pigment printing are not the same
- Reactive printing: dye bonds chemically with the fibre — softer hand, better colour fastness, more environmentally sound, higher cost
- Pigment printing: pigment sits on the surface bound by adhesive — simpler, cheaper, but stiffer and less wash-durable
When quotes differ a lot, ask which method it is before you start negotiating the price down.
8. Names that get confused
- Quilt shell / quilt filling — different names, sometimes the same item; don't compare them as two products
- Pattern is not the cost driver; the base fabric is. The same print on different base cloths can differ wildly in cost. Ask base first (material + GSM + width), pattern second
- "Class A" / formaldehyde-free claims need test reports behind them — they aren't defaults of the printing process
9. What to actually ask
| Buying | Parameters you must pin down |
|---|---|
| Fabric | Fibre content and ratios, yarn count (or warp×weft), density, GSM, width, weave, dye method, pricing unit (m/kg), MOQ, lead time |
| Finished bedding sets | Material, count, density, piece count, dimensions, finish (solid/printed/brushed), filling, packaging |
| Quilts / duvets | Shell material, filling material and weight, total weight, dimensions, finish |
| Stock lots (extra) | Quality grade, known defects (photographed), storage age, batch consistency |
