衣架上的衬衫往下滑，还留一圈胶印。包胶摩擦和耐温没配对，好衣服都废了。
衣服下滑不是没挂好，是摩擦不够
衣架包胶是“防滑挂衣的件”：防滑、阻燃、耐候。材料要防滑、阻燃、耐候——结论先给：衣架包胶用 SEBS 基 TPE 是主流；出口衣架，阻燃 TPE 优先。
衣架包胶最大的坑：阻燃等级差一级，应用差一个圈。阻燃差一级，应用差一圈——阻燃，是衣架的圈层线。
衣架包胶是日用品：打滑、开裂都是问题。材料选对，衣架才稳——日用品，别省料钱。
日晒热风天天烘，为什么用TPE
衣架包胶用 TPE 的理由：防滑可做、阻燃可做、耐候可做、效率高——四条合起来，适合包胶。
防滑是核心：挂衣防滑。防滑测试写进验收——滑落，就是问题。
阻燃不能省：出口要求。阻燃测试写进验收——等级差，就是问题。
挂衣、日晒、阻燃，三关各看什么
挂衣工况：挂衣防滑。防滑数据要验——滑落，就是问题。
日晒工况：阳台日晒。耐候数据要验——老化，就是问题。
阻燃工况：出口要求。阻燃数据要验——等级差，就是问题。

挂得稳不留印，验收测这四项
| 等级 | 应用 | 判断 |
|---|
| HB | 家用 | 达标 |
| V2 | 出口 | 达标 |
| V1 | 出口 | 达标 |
| V0 | 严苛 | 达标 |
表格读法：从普通料到阻燃料逐档过灼热丝，衣柜件别在等级上省——阻燃差一级，能进的场景就少一圈。
阻燃，是衣架的圈层线。
只看颜色不测阻燃，高温天最险
坑一：只看颜色。包胶衣架要进公共场所，阻燃报告缺了就被退——阻燃等级跟着走场景。
坑二：防滑漏测。滑落——防滑测试，必测。
坑三：耐候漏测。老化——耐候测试，必测。
摩擦、耐温、阻燃——做架前问清
三问：出口到哪里、阻燃等级多少、挂衣按什么标准。一验：实际使用实测——三问一验，供应商底细清楚。
阻燃验证要先行：按使用场所定灼热丝和氧指数，报告要齐。先测阻燃，再谈价格——阻燃，是衣架的圈层线。
留样要成习惯：每批留样，防滑阻燃按批次复测。批次换料先对比再放量——批次稳，客诉少。
下滑、留印、变色：故障对照一张表
| 现象 | 原因 | 对策 |
|---|
| 滑落 | 防滑不足 | 换防滑料 |
| 老化 | 耐候不足 | 换耐候料 |
| 等级差 | 阻燃不足 | 换阻燃料 |
| 开裂 | 柔韧不足 | 换高柔韧料 |
| 批次漂移 | 配方波动 | 锁窗口 |
衣架包胶挂着挂着，软胶从塑料骨上整块翻起——剥离力不够，衣服全滑地上。 PP基材包SEBS，剥离力低于0.5kN/m别量产；挂衣杆长期受拉，软胶不能脱。
衣架软胶Shore A 70上下，握挂扎实又不伤衣。 防滑纹路单独设计，光面挂衣必滑；剥离力验收1.0-2.0kN/m，弯折5000次不脱层。
PVC包胶便宜但有邻苯，TPE无邻苯还可回收。 衣柜封闭环境衣物贴身，TPE析出低；出口阻燃按客户等级，灼热丝750℃是及格线。
包胶验收三步：先测剥离力，再挂衣24h看不滑，最后过温湿循环。 基材PP表面除油，模温按SEBS体系调；软胶厚度0.8-1.2mm写进图纸。
衣服滑落不是衣架歪，是软胶防滑系数不够或硬度偏高。 防滑不是手感，是挂得住；调配方增摩擦纹路，比加粗衣架骨更治本。
衣架包胶要防滑又不勾丝，TPE 软而不粘、涩而不糙，太粘勾丝、太滑掉衣服。
选干爽防滑配方，挂湿衣服不滑肩；每批测表面手感和剥离力，软胶从骨上不脱再出货。
衣架还要耐洗、耐潮。 挂浴室潮气重，普通料久了发黏；每批复测表面，不粘丝不滑肩再放量。
衣架收尾验收：剥离力、防滑不勾丝、耐潮三项随批走。
每批留样测剥离力和挂湿衣摩擦，不滑肩不勾丝；批次换料先小批试挂，不脱边再出货。
科隆客户案例：耐油不足溶胀变形，跟产过1000h老化
扬州一家家居日用厂，衣架包胶耐油性不足，泡油后溶胀变形。科隆配合现场跟产调试到良率稳定，溶胀消除，一次性通过 1000h 老化测试。跟产调试，把溶胀锁死在量产前——耐油问题，先看配方再看参数。
小结
衣架包胶的选型，阻燃先测，防滑再验，阻燃等级差一级应用差一个圈，阻燃是圈层线。
The shirt on the hanger slid down, leaving a ring of adhesive marks. The coating and temperature resistance didn't match, and a good piece of clothing was ruined.
The clothes sliding down is not because they weren't hung properly, it's because there's not enough friction.
Hanger coating is a 'component for anti-slip clothing hanging': anti-slip, flame retardant, and weather resistant. The material should be anti-slip, flame retardant, and weather resistant — conclusion first: SEBS-based TPE is the mainstream for hanger coating; for export hangers, flame retardant TPE is preferred.
The biggest pitfall of coated hangers: the flame retardant rating is one level lower, and the application is one tier behind. One level lower in flame retardancy means one tier behind in application—the flame retardancy is the crucial layer line of the hanger.
Hanger coating is a daily necessity: slipping and cracking are problems. Only with the right material will the hanger be stable — for daily necessities, don’t skimp on material costs.
Baked by the sun and hot wind every day, why use TPE?
Reasons for using TPE to coat hangers: can be made non-slip, can be made flame-retardant, can be made weather-resistant, high efficiency — put together, suitable for coating.
Non-slip is key: hangers should be non-slip. Include non-slip testing in the inspection—if it slips, it's a problem.
Flame retardancy cannot be compromised: export requirements. Flame retardancy testing is included in the acceptance—if the rating is different, it's a problem.
Hanging clothes, sun drying, flame retardancy—what does each stage check?
Clothing hanging condition: anti-slip for hanging clothes. Anti-slip data must be tested—slipping is a problem.
Sun exposure condition: The balcony gets sunlight. Weather resistance data needs to be verified—aging is the issue.
Flame-retardant conditions: export requirements. Flame-retardant data need to be verified—the difference in grade is the problem.
TPE soft rubber versus PVC, which one to choose for hangers
| Dimension | SEBS-based TPE | PVC |
|---|
| Non-slip | Good | Can do |
| Flame retardant | Can do | Can do |
| weather-resistant | Good | general |
| smell | Controllable | Yi has flavor |
| Cost | Medium-high | Low |
| Purpose | mainstream | Low price |
Table reading: PVC is cheap but weather resistance and odor are average; TPE has good slip resistance and weather resistance — for hanger coating, TPE is mainstream.
Choose by positioning: mainstream TPE, low-cost PVC.
Hangs firmly without leaving marks, test these four items for acceptance
| Level | Application | Judgment |
|---|
| HB | Household | Meet the standard |
| V2 | Export | Meet the standard |
| V1 | Export | Meet the standard |
| V0 | harsh | Meet the standard |
Table reading method: Go through the glowing wire step by step from ordinary material to flame-retardant material. Do not save on grade for wardrobe items — if flame-retardant is one grade lower, the applicable scenarios are reduced by one circle.
Flame retardant is the looped line of the hanger.
Only looking at the color without testing for flame retardancy is most dangerous on hot days
Pitfall 1: Only look at the color. If rubber-coated hangers are to enter public places and the flame-retardant report is missing, they will be rejected — the flame-retardant rating follows the usage scenario.
Pitfall 2: Missed anti-slip testing. Slippage—anti-slip testing is a must.
Pitfall three: weather resistance omission. Aging—weather resistance testing must be conducted.
Friction, heat resistance, flame retardancy — check before building the frame
Three questions: where is it exported to, what is the flame-retardant rating, and according to what standard are clothes hung. One verification: test with actual usage — three questions and one verification, supplier details are clear.
Flame retardant verification must come first: determine the glow wire and oxygen index according to the place of use, and ensure the report is complete. Test for flame retardancy first, then discuss the price—flame retardancy is the circle line of the hanger.
Making sample retention a habit: retain samples from each batch, and retest slip resistance and flame retardancy by batch. When changing materials between batches, compare first before increasing the volume—stable batches result in fewer customer complaints.
Smudging, Fingerprints, Discoloration: A Fault Comparison Table
| Phenomenon | Reason | Countermeasure |
|---|
| slip | Insufficient slip resistance | Replace the anti-slip material |
| Aging | Insufficient weather resistance | Replace with weather-resistant material |
| Level difference | Insufficient flame retardancy | Change the fuel to flame retardant |
| Cracking | Insufficient flexibility | Switch to higher flexibility material |
| Batch Drift | Formula fluctuation | Lock window |
The hanger’s coating comes off while hanging, with the soft rubber peeling off the plastic skeleton in whole pieces—the peel strength is insufficient, causing clothes to slide to the floor. PP substrate coated with SEBS has a peel strength below 0.5 kN/m, not suitable for mass production; the hanging rod is under long-term tension, and the soft rubber cannot peel off.
The hanger's soft rubber has a Shore A hardness of around 70, making it sturdy to hold clothes without damaging them. The anti-slip pattern is specially designed; smooth hangers tend to slip. Peel strength is tested at 1.0-2.0 kN/m, and it does not delaminate after 5000 bends.
PVC coated with plastic is cheap but contains phthalates, while TPE is phthalate-free and recyclable. In a closed wardrobe environment with clothes in contact with the skin, TPE has low migration; for export flame retardancy, it depends on the customer's grade, with a glowing wire test of 750℃ being the passing line.
Three steps for overmolding inspection: first measure the peel strength, then hang the clothes for 24 hours to see if they don't slip, and finally pass the temperature and humidity cycle. Degrease the PP substrate surface, adjust the mold temperature according to the SEBS system; specify the soft rubber thickness of 0.8-1.2mm in the drawing.
Clothes slipping off is not because the hanger is crooked, but because the soft rubber's anti-slip coefficient is insufficient or its hardness is too high. Anti-slip is not about how it feels, but about being able to hold the clothes; adjusting the formula to increase friction patterns is more fundamental than just thickening the hanger's frame.
Hanger coating needs to be non-slip yet not catch threads. TPE is soft but not sticky, rough but not coarse; if it's too sticky it catches threads, if it's too slippery clothes fall off.
Choose a dry and non-slip formula, so wet clothes do not slip off the hanger; test each batch for surface feel and peel strength, and only ship when the soft rubber does not come off the base.
The hanger also needs to be wash-resistant and moisture-resistant. Hanging it in a bathroom with heavy humidity, ordinary materials will become sticky over time; each batch is re-tested for the surface, ensuring it does not catch threads or slip off the shoulders before increasing the quantity.
Hanger final inspection: Peel strength, anti-slip without snagging, and moisture resistance are checked in each batch.
Test the peel strength and wet clothes rubbing for each batch sample; ensure no slipping off the shoulders and no snagging. When changing materials for a batch, first do a small batch trial hang, and only ship after confirming no edge detachment.
Cologne Customer Case: Insufficient oil resistance causing swelling and deformation, compared with products aged over 1000 hours
A home daily-use products factory in Yangzhou had hangers with insufficient oil-resistant coating, which swelled and deformed after soaking in oil. Cologne cooperated on-site for production debugging until the yield stabilized, swelling was eliminated, and it passed the 1000-hour aging test in one go. During production debugging, we locked the swelling before mass production—regarding the oil resistance issue, first look at the formulation, then at the parameters.
Summary
For the selection of hangers with rubber coating, test for flame retardancy first, then check for anti-slip. If the flame retardant rating is lower by one level, the application is one circle less; flame retardancy is represented by the circle layer line.
