Introduction
In our previous article, we examined the global cooling towel market—its size, key drivers, and growth trajectory. Today, we invite you to step inside Wuxi East‑Sunshine Textile to see how high‑performance cooling towels are actually made.
In a rapidly growing market, quality and consistency matter more than ever. Buyers are increasingly looking beyond price—they want reliable sourcing, proven quality control, and full visibility into how their products are produced.
In this factory tour, we walk you through six critical stages of our cooling towel production: from raw material mixing, extrusion, and weaving, through sublimation printing and cutting, to final sewing, hemming, QC inspection, and packaging.
Each step is an opportunity to build quality in, not just inspect it out.
1. Raw Material Preparation: Where Performance Begins
All cooling towels start with raw materials—and at Donghui Factory, we start with the right ones.
Our cooling towels are made from microfiber, a blend of polyester and polyamide (nylon) . Polyester provides strength and durability, while polyamide contributes softness and high absorbency [2†L12-L14]. This combination creates the ideal fabric for evaporative cooling performance.

We offer both virgin and GRS‑certified recycled microfiber (rPET) —the recycled version is made from post‑consumer PET bottles, helping buyers meet their ESG and sustainability goals without compromising on performance. For rPET cooling towels, we provide transaction certificates with every shipment, allowing full traceability for your end customers.
2. Microfiber Extrusion & Weaving: Creating the Fabric
From raw pellets, the fabric‑making process begins.
The polyester and polyamide are melted and extruded through fine spinnerets to create ultra‑thin filaments—as fine as 1/100th the thickness of a human hair. These filaments are then woven or knitted into lightweight, breathable microfiber fabric that forms the base material for our cooling towels.

Our in‑house weaving allows us to control GSM (grams per square meter) precisely—typically 155–300 GSM for cooling towels, balancing lightweight portability with durability. Tighter weave structures improve abrasion resistance and edge stability during subsequent cutting and sewing.
3. Sublimation Printing: Adding Color That Lasts
Most of our cooling towels feature sublimation digital printing—a process that embeds dye directly into the fiber rather than coating the surface.
The process works as follows: designs are printed onto transfer paper using sublimation inks. The paper is placed onto the towel fabric, and under high heat (typically 180°C–220°C) and pressure, the solid ink converts directly into gas and bonds permanently with the polyester fibers [3†L31-L33] [3†L45-L46].

Unlike surface printing, sublimation produces permanent, wash‑fast colors that will not crack, peel, or fade—even after hundreds of uses. The printed surface remains smooth, with no change in hand feel or cooling performance. This makes sublimation ideal for vibrant brand logos, detailed patterns, or photo‑quality designs.

For B2B buyers, this means your branding stays sharp and durable through the full product lifecycle—an important consideration for promotional products, sports team merchandise, and corporate gift programs.
4. Precision Cutting: Consistency in Every Piece
Once the printed fabric is ready, it moves to our cutting station.
We use industrial‑grade automated cutting systems to cut fabric into individual towel blanks with size tolerance within 0.5 cm. Consistent dimensions ensure that each towel fits packaging perfectly and meets customer expectations for uniformity.

The automated process also minimizes edge fraying, which is essential for the next stage: sewing and hemming. Clean, consistent cuts reduce waste and improve production efficiency—benefits that translate into stable lead times for our customers.
5. Sewing & Hemming: Finishing That Lasts
After cutting, each cooling towel undergoes edge finishing to ensure long‑term durability.
At Donghui Factory, we use double‑needle hemming—two parallel rows of stitching that create a flat, reinforced edge. This method prevents fraying, secures loose threads, and maintains the towel’s structural integrity through repeated washing.

A strong hem is not just about aesthetics—it directly affects how long a cooling towel remains usable in real‑world conditions, whether in a gym bag, on a construction site, or packed for travel. For B2B buyers, this means fewer returns and better end‑user satisfaction.
6. Quality Control: Testing What Matters
Quality is not a single inspection step—it is a system embedded throughout production.
At each stage of our process, from raw material intake through weaving, printing, cutting, and sewing, we conduct in‑process checks. Then, before any batch is packed, we perform final random sampling to verify:
- Absorbency rate – ensures the towel can retain sufficient moisture for sustained evaporative cooling
- Color fastness (rubbing and washing) – Grade 4+ required
- Shrinkage – ≤ 3% after washing
- Edge stitch quality – no loose threads or uneven hemming

We retain samples from every production lot for 12 months, ensuring full traceability. When requested, we also arrange third‑party lab testing (SGS/Intertek) to validate cooling performance—including ASTM F3628 (Standard Test Method for Measuring Cooling Energy) where applicable [1†L6-L9].
7. Packaging & Logistics: Ready for Global Delivery
Once inspected and approved, cooling towels are folded or rolled and packed according to customer specifications—from polybags for retail display to bulk cartons for wholesale distribution.
We offer flexible packaging options:
- Polybag with hang tag – retail‑ready, ideal for consumer brands
- Plain polybag – economical, suitable for promotional giveaways
- Custom packaging – full branding on boxes or sleeves
