Ⅰ. The four most common types of fabric for phone cases
Choose the plan that suits you best.




| Feel | Advantages | Disadvantages | Applications | |
| plush / Flannel |
Soft, warm, and skin-friendly. It gets warm when touched in winter |
(1) Good heat protection effect, unlikely to get cold burns (2)Good wrapping property, not likely to slip |
(1)Easy to lose hair and prone to balling up (2)Washed with water, it is prone to deformation |
(1)Europe, the United Kingdom, Russia, Eastern Europe (2) Ordinary household models, mass production models |
| Coral Fleece | More fluffy and softer than short plush | (1) Excellent warmth retention (2) Less shedding than velvet |
Thick and bulky, with slightly higher shipping cost | High-end household use and gift items |
| Knitted fabric | Thin, breathable, close-fitting | (1)Washable and does not deform (2) Can be printed with patterns and made into brand models |
Flame-retardant performance is average; be mindful of thickness | Medical therapy, simple styles, brand customization |
| Cotton fabric / Cotton and polyester blend | Strong, crisp, durable | (1)The most wear-resistant, not prone to breaking (2)Low cost, easy to produce |
A bit hard, average feel | Traditional old-style models, low-priced mass production, African/Middle Eastern markets |
Ⅱ. Ranked by "Safety + Heat Protection"
1. Short plush / Flannel → The safest and best at resisting heat.
2. Coral Fleece
3. Knitted Cotton
4. Cotton Fabric / Polyester Cotton
Reason: The thicker and softer the plush material is, the better its heat insulation performance is, and it can significantly reduce the risks of low-temperature burns and skin swelling. This is why supermarkets in the EU and the UK are now giving priority to promoting plush covers to reduce safety incidents.
III. Ranked by "Cost & Quantity"
1. Cotton fabric / TC cotton blend → The cheapest and most reliable
2. Knitted fabric
3. Short plush
4. Coral fleece → The most expensive
IV. Pitfalls to Avoid When Exporting
1. Dyes are carcinogenic and allergenic
- The European Union/United Kingdom is investigating AZO azo dyes
- Required documents: A report on no azo content test
2. Long fur poses a suffocation risk
- Long fur can be pulled and tangled by children
- Children's models usually require short fur and tight weaving
3. Incompatible size leads to sliding
- The cover is too loose → The hot water bag moves inside → Local overheating and burns
- Inspection points: It should not slide or expose rubber after being put on
V. Here is a straightforward and applicable summary for you.
- For safety, heat resistance and good sales in Europe and America: Choose short plush/velvet fabric covers.
- For low cost, durability and large quantity: Choose cotton/nylon fabric covers.
- For brand, gift and high-end: Choose coral fleece or fine-combed knitted covers.
