How we develop new textures with brands
Most of our development work starts from a brand’s brief, not from a lab. A typical project runs in four steps:
Action Step
Brief — the feel, thickness and use you want (for example a pad that holds more toner, or a towel that feels thicker without more weight).
Action Step
Fabric and pattern trials — we test fiber blends, GSM and embossing depth on short runs.
Action Step
Testing — weight, thickness, absorbency and lint checks on trial samples; third-party tests when your market needs them (see quality control).
Action Step
Approval and tooling — once you approve a sample, we make the production roller (see custom embossing patterns).
R&D team: 6 dedicated R&D and QC engineers (pattern tooling, substrate testing & packaging dielines). Development equipment: precision GSM analytical balances, digital tensile testers, caliper gauges, 365 nm UV inspection lamps and ultrasonic sample sealers.

What the patents mean for buyers
Our patterned pads are ZEFU’s own registered designs, so your product does not copy another company’s pattern.
A China design patent lets the holder act against copies made or sold in China.
Exclusive use of a pattern in your market can be agreed in writing; for a pattern nobody else has, choose a custom roller.

FAQ
Q1Are ZEFU’s patents valid outside China?+
No. They are China patents and protect the designs and method in China. Protection in other countries needs separate registrations there.
Q2Can we license a patented pattern for our brand?+
You can use our patterns on products made by ZEFU. Exclusive rights for a market are agreed case by case.
Q3What is the scented-fabric patent?+
It is an invention patent (ZL 2020 1 0785651.1) for a method of making a scented fabric, and the fabric itself.
