梳子一梳就扯头发，客户说扎头皮。梳齿软硬度没调对，舒服和断发一线间。
扯头发不是梳得狠，是齿尖硬度不对
梳子是“梳齿减震的件”：柔软、减震、防静电。材料要柔软、减震、防静电——结论先给：梳齿软胶用 SEBS 基 TPE 是主流；气垫梳，TPV 复合留。
梳子最大的坑：厚度加0.3mm，减震差一档。厚度差一点，减震差一档——厚度，是梳子的减震线。
梳子是日用品：发硬、开裂都是问题。材料选对，梳子才稳——日用品，别省料钱。
天天梳头受热，为什么用TPE
梳子用 TPE 的理由：柔软可做、减震可做、防静电可做、效率高——四条合起来，适合梳子。
柔软是核心：梳齿触感。柔软测试写进验收——发硬，就是问题。
减震不能省：梳头缓冲。减震测试写进验收——震感，就是问题。
梳头、加热、静电，三关各看什么
梳头工况：梳头缓冲。减震数据要验——震感，就是问题。
加热工况：吹风加热。耐温数据要验——变形，就是问题。
静电工况：防静电。防静电数据要验——炸毛，就是问题。
软胶TPE对阵硬PP，梳子选谁
| 维度 | SEBS基TPE | PP |
|---|
| 柔软 | 好 | 硬 |
| 减震 | 可做 | 差 |
| 防静电 | 可做 | 一般 |
| 耐温 | 可做 | 好 |
| 成本 | 中高 | 低 |
| 用途 | 软齿 | 硬齿 |
表格读法：PP 便宜但硬、减震差；TPE 柔软减震好——软齿 TPE，硬齿 PP。
按齿型选：硬齿 PP，软齿 TPE。
不扯不痒不起静电，验收测这四项
| 厚度 | 减震 | 判断 |
|---|
| 1.0mm | 弱 | 偏薄 |
| 1.3mm | 适中 | 达标 |
| 1.6mm | 好 | 达标 |
| 1.9mm | 过软 | 偏厚 |
表格读法：梳齿软胶层卡尺量，厚一点缓冲就多一截——厚度差零点几毫米，梳头的软弹感跟着变。
厚度，是梳子的减震线。
只看外观不调硬度，梳头就夹发
坑一：只看外观。看着差不多，梳头皮那一下软硬两回事——软胶层厚度，直接决定按摩感。
坑二：耐温漏测。变形——耐温测试，必测。
坑三：柔软虚标。发硬——柔软按实测验收。
齿尖硬度、厚度、回弹——做梳前问清
三问：齿厚多少、耐温多少、减震按什么测试。一验：实际使用实测——三问一验，供应商底细清楚。
厚度验证要先行：按梳齿接触面积定软胶层，卡尺抽测。先定厚度，再谈价格——厚度，是梳子的减震线。
留样要成习惯：每批留样，柔软减震按批次复测。批次换料先对比再放量——批次稳，客诉少。
夹发、断齿、静电：故障对照一张表
| 现象 | 原因 | 对策 |
|---|
| 发硬 | 硬度偏高 | 降硬度 |
| 震感 | 减震不足 | 加厚度 |
| 变形 | 耐温不足 | 换耐温料 |
| 炸毛 | 防静电差 | 加防静电剂 |
| 批次漂移 | 配方波动 | 锁窗口 |
好梳子的齿尖要像猫舌——顺滑带弹，梳过头皮不扎。 TPE包胶齿或全软TPE梳，Shore A 60-70糯感适中，太硬扎头皮、太软梳不动结。
齿厚差0.3mm，减震差一档——软齿减震靠厚度也靠回弹。 弯折不挂头皮，耐折按反复梳理次数核；防静电配方减少梳发炸毛。
梳头扯头发，不是齿太密，是齿端回弹和顺滑度没配好。 静电炸毛多是材料吸纤起电，选抗静电母粒；贴肤面要哑光不粘灰。
打样前先答三问：梳什么发质、每天梳多久、干用还是湿发用。 答案定硬度档与耐水配方；盲测评分后再定量产齿厚。
新梳子滑溜溜，放一个月齿缝冒白霜——充油过量析出，客户直接退货。
析出发白不是料脏，是油析出来；选相容好的低充油配方，7天观察面不发白。
梳子天天梳又洗，TPE 包胶要耐洗、不发黏，齿部要硬弹不刮头皮。
沾水沾洗发水，普通料久了表面发黏；选耐洗护配方，洗几百次不黏手、不变软塌，梳齿圆润不刮头皮。
梳子又是包胶件，软皮包硬骨剥离力要够。 手柄软胶从 PP 齿柄上脱开就是客诉；SEBS 基包 PP 剥离力典型 1.0-2.0kN/m，弯折不开胶再放行。
梳子收尾验收：剥离力、耐洗护、齿部圆润三项随批走。
每批留样测剥离力和洗几百次后表面，不黏不刮头；批次换料先小批试梳，不脱胶再放量。
梳子选型说到底，是把剥离力、耐洗护、梳齿圆润三件事一次问清。 PP 齿柄包 SEBS 软胶，剥离力 1.0-2.0kN/m，洗发水洗几百次不黏手；先小批试梳，不刮头再放量。
科隆客户案例：收缩率不稳尺寸波动，小批试产续三单
金华一家家居日用厂，梳子收缩率不稳，尺寸波动大。科隆配合小批试产验证后再放量，尺寸稳定，客户连续三个批次续单。小批试产，把尺寸锁死在放量前——收缩率问题，试产阶段就该暴露。
小结
梳子材料的选型，厚度先定，减震再测，厚度加0.3mm减震差一档，厚度是减震线。
The comb pulls hair as soon as you comb it, and the client says it pinches the scalp. If the comb teeth are not adjusted for hardness correctly, comfort and hair breakage are on a fine line.
Pulling hair is not about brushing hard, it's about the tip of the teeth not being the right hardness
A comb is a 'tooth shock-absorbing component': soft, shock-absorbing, and anti-static. The material should be soft, shock-absorbing, and anti-static—the conclusion first: for comb teeth, soft rubber using SEBS-based TPE is mainstream; for air cushion combs, TPV composite is retained.
The biggest flaw of the comb: if the thickness increases by 0.3mm, the shock absorption decreases by one level. If the thickness is slightly off, the shock absorption decreases by one level — the thickness is the comb's shock absorption line.
A comb is an everyday item: issues arise when it is hard or cracked. Choosing the right material ensures the comb's durability—everyday items are not the place to skimp on materials.
Combing hair every day with heat, why use TPE?
Reasons for using TPE for combs: can be made soft, can provide shock absorption, can be made anti-static, high efficiency—together, these four make it suitable for combs.
Softness is key: the feel of the comb teeth. Softness testing is included in acceptance inspections—if it hardens, it's a problem.
Shock absorption cannot be skimped on: cushioning when combing hair. Include shock absorption testing in the acceptance inspection — if you can feel the vibration, it's a problem.
Combing, heating, static electricity—what to look at for each of the three stages
Combing operation condition: combing cushioning. Shock absorption data needs to be checked — the vibration sensation is the problem.
Heating condition: Air-blow heating. Temperature resistance data must be verified—deformation means there is a problem.
Static electricity condition: anti-static. Anti-static data must be verified—frizzing, that's the problem.
Soft TPE vs. hard PP, which one to choose for a comb
| Dimension | SEBS-based TPE | PP |
|---|
| Soft | Good | hard |
| Shock absorption | Can be done | poor |
| Anti-static | Can be done | general |
| Temperature resistant | Can be done | Good |
| Cost | Medium-high | Low |
| Purpose | soft teeth | Hardened tooth |
Table reading: PP is cheap but hard, with poor shock absorption; TPE is soft with good shock absorption — soft-tooth TPE, hard-tooth PP.
Choose according to tooth shape: hard teeth PP, soft teeth TPE.
No tugging, no itching, no static electricity; test these four items for acceptance
| Thickness | Shock absorption | Judgment |
|---|
| 1.0 mm | Weak | relatively thin |
| 1.3 mm | Moderate | Meet the standard |
| 1.6mm | Good | Meet the standard |
| 1.9mm | Too soft | Somewhat thick |
Table reading: Measured with a comb-tooth soft rubber layer caliper, a slightly thicker cushion adds a bit more—thickness difference is just a few tenths of a millimeter, and the soft springy feel of the comb changes accordingly.
Thickness is the shock-absorbing line of the comb.
Only looking at the appearance without adjusting the hardness, combing hair gets stuck
Pitfall one: Only look at the appearance. It looks similar, but the feeling when combing the scalp is a completely different matter—the thickness of the soft rubber layer directly determines the massaging sensation.
Pitfall 2: Missed temperature resistance test. Deformation — temperature resistance test, must be checked.
Pitfall 3: Softness falsely advertised. Hard — softness should be accepted based on actual testing.
Tip hardness, thickness, resilience—ask before combing
Three questions: How thick are the teeth, what is the temperature resistance, and according to what test is the shock absorption measured? One verification: actual measurement in practical use — three questions and one verification, the supplier’s background is clear.
Thickness verification must come first: determine the soft rubber layer according to the comb tooth contact area, and measure with calipers. Set the thickness first, then discuss the price—the thickness is the comb's shock-absorbing line.
Making sample retention a habit: retain samples from each batch, and retest softness and shock absorption by batch. When changing materials for a batch, compare first before scaling up—the more stable the batch, the fewer the customer complaints.
Hair Clipping, Broken Teeth, Static Electricity: A Fault Comparison Table
| Phenomenon | Reason | Countermeasure |
|---|
| become hard | Hardness is relatively high | Reduce hardness |
| Vibration | Insufficient shock absorption | Increase thickness |
| Transformation | Insufficient temperature resistance | Change to heat-resistant material |
| frizzy hair | Poor anti-static | Add anti-static agent |
| Batch Drift | Formula fluctuation | Lock window |
A good comb's teeth tips should be like a cat's tongue—smooth and springy, gliding over the scalp without pricking. Combs with TPE-coated teeth or fully soft TPE combs, with a Shore A hardness of 60-70, have moderate tackiness; too hard will prick the scalp, too soft won't detangle knots.
Tooth thickness difference of 0.3mm, one level lower in shock absorption — soft teeth rely on both thickness and rebound for cushioning. Bends won't catch the scalp, durability is measured by repeated combing; anti-static formula reduces frizz.
Combing hair and pulling it out is not because the teeth are too close together, but because the rebound and smoothness of the teeth ends are not matched. Most static frizz is caused by the material attracting fibers and generating electricity, so choose anti-static masterbatch; the side that touches the skin should be matte and not attract dust.
Answer three questions before prototyping: what hair type are you combing, how long do you comb each day, and are you using it on dry or wet hair. The answers determine the hardness level and water-resistant formula; after blind testing and scoring, the production tooth thickness is determined.
The new comb is very smooth. After being left for a month, white residue appears between the teeth — this is caused by excess oil separation, and the customer returns it immediately.
The whitening caused by oil exudation is not due to dirty material, but because the oil comes out; choose compatible formulations with low oil content, and the surface will not whiten after 7 days of observation.
Combs are used every day and washed frequently. TPE coating needs to be wash-resistant and non-sticky, and the teeth should be firm and springy without scratching the scalp.
When it gets wet or comes into contact with shampoo, ordinary materials become sticky on the surface over time; choosing a formula resistant to washing allows hundreds of washes without becoming sticky or soft and flat, and the comb teeth are smooth and do not scratch the scalp.
The comb is also over-molded, and the soft coating must have enough peel strength against the hard base. If the soft rubber handle detaches from the PP tooth handle, it will result in customer complaints; for SEBS-based coating on PP, the typical peel strength is 1.0-2.0 kN/m. If it doesn't peel when bent, it can be approved.
Comb final inspection: Peel strength, wash resistance, and smoothness of teeth are checked randomly for each batch.
Each batch is sampled to test peel strength and after washing hundreds of times, the surface is not sticky and does not scratch; when changing materials for a batch, first do a small test combing, and only if there is no delamination, proceed with full production.
When it comes to choosing a comb, it ultimately comes down to asking about three things at once: detachment force, wash resistance, and the smoothness of the teeth. PP teeth and handle wrapped with SEBS soft rubber, detachment force 1.0-2.0 kN/m, won't become sticky after washing with shampoo hundreds of times; start with a small batch for trial combing, and only increase quantity if it doesn't scratch the scalp.
Cologne Customer Case: Unstable Shrinkage Rate and Size Fluctuations, Small Batch Trial Production Continues with Three Orders
Jinhua household daily-use factory, comb shrinkage rate is unstable, size fluctuates greatly. Cologne coordinates with small-batch trial production for validation before scaling up, stable size, customer renews orders for three consecutive batches. Small-batch trial production locks in size before ramping up—shrinkage issue should be exposed during trial production.
Summary
Comb material selection: thickness determined first, shock absorption then measured; thickness plus 0.3mm shock absorption differs by one stop, thickness is the shock absorption line
