Not every waterproof fabric project starts with an existing product.
Sometimes a customer knows exactly what they need:
“We need a waterproof fabric for a mattress protector, but it needs to be softer, lighter, and more breathable.”
Other times, the requirements are much more specific:
A particular fabric surface
A specific GSM
A certain TPU thickness
Custom color
Special width
Higher washing durability
A specific price target
For OEM customers, finding the right waterproof fabric is therefore not simply a matter of choosing a product from a catalog.
It is a development process.
At Meihu, we work with customers to turn their product requirements into a practical waterproof fabric solution—from the first inquiry to sampling and mass production.
Here’s what that process typically looks like.
Step 1: Understanding the Customer’s Application
The first step isn’t choosing the fabric.
It’s understanding what the fabric will be used for.
A waterproof fabric for a mattress protector may have very different requirements from one used for:
Medical bedding
Nursing care products
Hotel bedding
Pet products
Waterproof pillow protectors
Incontinence products
For example, a customer producing mattress protectors may prioritize:
Softness + Breathability + Waterproof Performance
A healthcare customer may place greater emphasis on:
Durability + Washing Performance + Chemical Resistance
Understanding the final application helps us recommend the appropriate construction rather than simply offering the lowest-priced material.
Step 2: Confirming the Technical Requirements
Once the application is clear, we confirm the technical specifications.
Typical requirements include:
Face fabric
Fabric composition
GSM
Fabric width
TPU thickness
Color
Waterproof performance
Breathability requirements
Washing requirements
Roll length
Packaging
For example, a customer may request:
Knitted fabric + TPU
160 GSM
230 cm width
Custom color
Suitable for waterproof mattress protectors
These specifications provide a starting point for product development.
Step 3: Selecting the Right Face Fabric
The surface fabric has a major influence on how the finished product feels and performs.
Depending on the application, we may recommend:
Cotton Terry
Soft, absorbent, and suitable for bedding products where comfort is important.
Knitted Fabric
Stretchable, soft, and comfortable against the skin.
Microfiber
Lightweight, smooth, and suitable for a variety of bedding applications.
Coral Fleece
Soft and warm, making it suitable for products where warmth and comfort are priorities.
Bamboo or Tencel Fabrics
Suitable for customers looking for specific fiber characteristics and a more premium positioning.
The right choice depends on the customer’s target product rather than simply choosing the most expensive material.
Step 4: Selecting the TPU Layer
The TPU membrane is responsible for the waterproof barrier.
Its specification needs to be considered together with the face fabric and final application.
Important factors include:
TPU thickness
Waterproof performance
Flexibility
Breathability
Intended washing conditions
Final product requirements
A thicker TPU layer is not automatically better for every application.
For some bedding products, customers may prefer a thinner and more flexible construction while still achieving the required waterproof performance.
That’s why we evaluate the complete fabric construction rather than focusing on one specification alone.
Step 5: Developing the First Sample
After the requirements are confirmed, we prepare a sample for evaluation.
The sample allows the customer to check:
Hand feel
Appearance
Thickness
Color
Waterproof performance
Overall suitability
This stage is important because specifications on paper cannot completely describe how a fabric feels and performs in a finished product.
If the first sample isn’t exactly right, we discuss the customer’s feedback and adjust the construction.
Step 6: Adjusting the Fabric Based on Feedback
OEM development is rarely a one-step process.
For example, a customer may say:
“The fabric is waterproof enough, but we need a softer hand feel.”
Or:
“The fabric looks good, but we need to reduce the weight.”
Or:
“We need better breathability for our target market.”
Based on this feedback, we may adjust factors such as:
Face fabric
GSM
TPU specification
Fabric construction
Color
Overall thickness
The objective is to find the right balance between performance, comfort, appearance, and cost.
Step 7: Sample Approval
Once the customer is satisfied with the sample, the specifications are confirmed.
This becomes an important reference for mass production.
The approved sample and technical requirements help both sides maintain a clear understanding of what the final product should be.
For long-term OEM projects, maintaining consistency between the approved sample and future production is especially important.
Step 8: Mass Production
After approval, production can begin.
The confirmed specifications are transferred into the production process.
During production, key factors such as:
Material specifications
Lamination conditions
Fabric appearance
Width
Roll length
Finished quality
are monitored according to the customer’s requirements.
Quality control is performed throughout the production process rather than only at the end.
Step 9: Final Inspection and Shipment
Before shipment, finished rolls are inspected and prepared according to the agreed requirements.
The final stage includes checks such as:
Appearance
Specifications
Quantity
Packaging
Labels
Shipping marks
After the inspection is completed, the finished waterproof fabric is ready for shipment.
The development process that began with a simple customer inquiry has now become a finished product ready for the customer’s production line.
Why OEM Development Matters
For many B2B customers, an off-the-shelf waterproof fabric isn’t enough.
Their products may require a specific combination of:
Comfort + Waterproof Performance + Appearance + Durability + Cost
A manufacturer with OEM development experience can help customers find a practical balance between these requirements.
The goal isn’t simply to create a custom fabric.
It’s to create a fabric that works for the customer’s actual product and market.
A Simple OEM Development Process
Our typical development process can be summarized as:
Customer Inquiry
↓
Application & Requirement Analysis
↓
Material & TPU Selection
↓
Sample Development
↓
Customer Evaluation
↓
Specification Adjustment
↓
Sample Approval
↓
Mass Production
↓
Quality Inspection
↓
Shipment
This process gives both the customer and manufacturer clear checkpoints before moving to the next stage.
What Information Should You Send When Requesting a Custom Fabric?
If you’re contacting a waterproof fabric manufacturer for an OEM project, providing as much information as possible can make the development process faster.
Useful information includes:
Final product application
Desired fabric composition
Target GSM
Width
Color
Waterproof requirements
Breathability requirements
Washing conditions
Estimated order quantity
Target price, if available
If you don’t have all of these specifications yet, that’s okay.
A good manufacturer should be able to discuss the application with you and help determine the most suitable construction.
From an Idea to a Production-Ready Fabric
A successful OEM project is not simply about receiving a quotation.
It’s about communication, testing, adjustment, and consistency.
At Meihu, we work with customers to develop TPU laminated waterproof fabrics for mattress protectors, pillow protectors, healthcare products, hospitality applications, and other waterproof textile products.
If you have a specific fabric requirement but aren’t sure which construction is right for your product, send us your application and requirements.
We’ll work with you to evaluate the possibilities and develop a practical solution.
