给猫梳毛梳齿一刮就红，主人不敢再用。梳齿太硬伤皮，软硬没调对。
一刮就红，不是梳得狠是齿太硬
宠物梳子手柄包胶是“手感件”：软硬、包胶、安全。材料要护住皮肤——结论先给：宠物梳齿，软硬不伤皮肤——软硬，是梳子的分寸。
宠物梳子最大的坑：齿太硬刮红皮肤、太软梳不开结——软硬，是梳子的天平。
宠物件是体验件：伤肤、脱层都是问题。材料选对，体验才稳——宠物件，别省配方。
手感包胶都要，TPE为什么合适
宠物梳子用 TPE 的理由：手感可做、包胶可做、安全可做——三条合起来，适合梳子。
手感是核心：握持舒适。手感测试写进验收——偏硬，就是问题。
包胶不能省：梳齿缓冲。包胶测试写进验收——脱层，就是问题。
梳齿、握持、安全，三关各看什么
梳齿工况：梳毛不伤皮。软硬数据要验——伤肤，就是问题。
握持工况：手柄舒适。手感数据要验——偏硬，就是问题。
安全工况：接触皮肤。安全数据要验——超标，就是问题。

梳齿太硬刮红皮肤，太软梳不透毛——软硬按部位分。 一个硬度做整件，不是伤皮就是梳不干净。
包胶手柄手汗一握就发滑，梳齿在宠物身上打滑。 湿态防滑要按沾湿毛发测，不是干手转一下，滑了就抓不住。
梳齿中软、手柄软、梳背硬，三种硬度一个件。 软硬按部位配，别一个料做整件，部位不同手感不同。
包胶是手柄的“第二层皮”，剥离力不够用两周就脱。 剥离力过0.5kN/m安全线、弯折不脱胶，手柄才经得住天天握。
梳齿硬度卡到中软不伤皮、包胶剥离达标，梳子用半年不脱胶不变硬。 盲测梳齿舒适度再放量，别让宠物和主人都受罪。
梳子手柄剥离力过0.5kN/m安全线，弯折不脱胶才经得住天天握。ABS基材配SEBS包胶，剥离力典型1.0-2.0kN/m，手汗长期浸不脱层才算过。
梳子齿部软硬按宠物毛长配，别一个硬度做整件。梳齿用Shore A 30-40不伤皮肤，手柄用Shore A 60-70湿手不滑，湿态沾毛测试不打滑才放行。

宠物梳子的选型，软硬先定，包胶再测，宠物梳齿软硬不伤皮肤，软硬是分寸。
Brushing the cat's fur makes its skin red after just one stroke, so the owner doesn't dare to use it anymore. The brush teeth are too hard and hurt the skin; the softness and hardness are not properly adjusted.
It turns red with just a scratch; it's not that I'm brushing hard, it's that the teeth are too hard.
The handle of a pet brush is covered with rubber and is a 'tactile component': hardness, rubber coating, safety. The material should protect the skin — conclusion first: the teeth of the pet brush are neither too hard nor too soft, and do not hurt the skin — the hardness is the measure of the brush.
The biggest pitfall of pet brushes: teeth that are too hard can scratch the skin red, and teeth that are too soft can't detangle — softness and hardness are the balance of the brush.
Pet products are experience products: skin irritation and delamination are both problems. Choosing the right material ensures a stable experience — for pet products, don’t skimp on the formula.
Both the feel and the rubber coating are needed, why is TPE suitable?
Reasons for using TPE for pet combs: good tactile feel, can be coated, safe — combining all three, suitable for combs.
Feel is key: comfortable to hold. Handfeel testing is included in the acceptance criteria—if it's too hard, that's a problem.
Coating cannot be skipped: comb tooth cushioning. Include coating testing in the acceptance—delamination is the problem.
Comb teeth, grip, safety—what does each of the three checks look at?
Comb teeth condition: Combing wool without hurting the skin. The softness and hardness data must be checked—if it hurts the skin, it's a problem.
Grip condition: The handle is comfortable. The tactile data needs to be checked — if it's slightly hard, that's a problem.
Safety condition: Contact with skin. Safety data must be checked—if it exceeds the standard, that's a problem.
Pet brush materials, a table clearly comparing them
| Body part | Material | Hardness |
|---|
| Comb teeth | TPE | ChinaSoft |
| Handle | TPE | soft |
| comb your back | ABS | hard |
| Encapsulation | TPE | soft |
How to read the table: divide materials by part, follow hardness accordingly, and classify comb tooth softness based on pet hair.
Choose according to the part, the softness or hardness is correct.
Combing smoothly without hurting the skin, check these four items
| Project | Requirement | Judgment |
|---|
| soft and hard | By part | Meet the standard |
| Overmolding | Test | Meet the standard |
| Safety | Certification | Meet the standard |
| Batch | Lock | Meet the standard |
Form reading method: Check each item one by one, the experience is visible, and the rubber-coated grip area is inspected separately.
Softness and hardness are the measure of a comb.
Only look at the appearance without checking the coating; return it if it damages the leather.
Pitfall 1: Only looking at appearance. A comb may look good in teeth shape but scratch the skin, causing cats and dogs to hide as soon as you brush them—softness and hardness must be tested.
Pitfall 2: Incomplete testing of coating. Delamination — coating must be tested.
Pitfall three: safety testing omissions. Exceeding standards—safety must be tested.
Tips, coating, hardness—ask clearly before making a comb
Three questions: what pet, what grip feeling, what certification. One verification: actual usage testing - three questions and one verification, the supplier's details are clear.
Softness and hardness testing must come first: first fix the Shore A hardness of the comb teeth and the hardness of the grip area, then discuss the feel of the rubber coating—softness and hardness determine the proportions of the comb.
Making sample retention a habit: retain samples from each batch, and re-test the feel of the coated material by batch. When changing materials between batches, compare first before increasing the volume—stable batches result in fewer customer complaints.
Scratches, Chipped Teeth, Glue Detachment: A Fault Comparison Table
| Phenomenon | Reason | Countermeasure |
|---|
| skin-damaging | The comb teeth are hard | Adjust softness |
| Delamination | Unclean substrate | Clean the substrate |
| Somewhat hard | The handle is stiff | Formulate a prescription |
| Exceed the standard | Unsafe | Switch to food-grade |
| Batch bleaching | Formula fluctuation | Lock window |
If the bristles are too hard, they scratch and redden the skin; if too soft, they can't comb through the fur — the hardness should be divided according to the body part. One level of hardness for the whole body either injures the skin or doesn't comb cleanly.
The rubber-coated handle becomes slippery as soon as hands sweat, and the comb teeth slip on the pet. Wet-state anti-slip should be measured by applying it to wet hair, not just turning with dry hands; if it slips, it can't be held.
The comb teeth are soft, the handle is soft, and the back of the comb is hard—all three hardness levels in one piece. The softness and hardness are matched according to the part; it is not made from a single material for the whole piece, so different parts feel different.
Overmolding is the 'second layer of skin' on a handle. If the peel strength is insufficient, it will come off in two weeks. Only when the peel strength exceeds the safety threshold of 0.5 kN/m and does not peel off when bent can the handle withstand daily use.
The comb teeth are medium-soft in hardness, which does not hurt the skin, and the rubber coating meets the standard for peeling resistance. The comb can be used for half a year without the rubber coming off or hardening. Blind test the comfort of the comb teeth on a larger scale so that neither pets nor owners suffer.
The comb handle must withstand a peel force over 0.5 kN/m without detaching or bending to endure daily use. ABS substrate with SEBS overmolding has a typical peel force of 1.0-2.0 kN/m, and it only counts as passing if prolonged exposure to hand sweat does not cause delamination.
The comb's teeth hardness is adjusted according to the length of the pet's fur; do not make the entire piece with a single hardness. The comb teeth use Shore A 30-40 so as not to hurt the skin, and the handle uses Shore A 60-70 to prevent slipping when wet. It is only approved after passing the wet-state hair adhesion test without slipping.
Peeling force over 0.5 kN/m ensures that the adhesive does not come off when bent, so the handle can withstand daily use. Wet-state anti-slip is tested by touching wet hair, not by turning it with dry hands; softness and hardness are matched according to the part, and another material is used for the whole piece.
If the stiffness is made for the whole piece, it either hurts the skin or can't be combed cleanly.
Wet-state slip resistance should be measured by wet hair, not by turning with dry hands and claiming it slips and can't be grasped. The softness and hardness should be matched according to the part, using different materials for the whole piece so that different parts have different textures.
The comb teeth use Shore A 30-40 so as not to hurt the skin, and the handle uses 60-70 to prevent slipping when wet. The peeling strength must exceed 0.5 kN/m, and the safety line must bend without delaminating to withstand daily use. The product is only approved if it does not slip during wet hair adhesion tests.
Cologne customer case: high rework rate of delaminated coating, reproduce the feel according to production benchmark
A pet supplies factory in Jiaxing had issues with mass delamination of rubber-coated parts of pet combs, and the rework rate remained high. Kolon cooperated on-site with production debugging until the yield stabilized, delamination was eliminated, and the tactile rebound matched the sample. During production debugging, the delamination was locked down before mass production — for rubber coating issues, first look at the substrate, then at the parameters.
Summary
When choosing a pet comb, first determine the hardness, then test with rubber coating. The teeth of a pet comb should be soft enough not to hurt the skin, and the hardness must be measured carefully.
