Trend Observation
For AW26/27, denim washing is at a watershed. Traditional stone washing and bleaching, due to high water consumption and chemical residues, are being rapidly replaced by laser engraving, ozone washing, and enzyme washing. Humen and Xintang, as core denim industry belts in China, have taken the lead in introducing hundreds of laser machines and ozone equipment. Washing workshops are shifting from "wet processing" to a hybrid of dry and wet. This transition not only reduces environmental pressure but also makes distressing effects precise and controllable rather than random.
Laser engraving is becoming mainstream for distressing in AW26/27. High-precision lasers burn whiskers, holes, and faded textures onto denim surfaces without water or chemicals. Processing time per garment is reduced to 30-60 seconds. Factories in Humen report that laser engraving can replicate traditional hand-sanding effects, and patterns can be stored digitally for easy small-batch reorders. Xintang combines laser with ozone—laser first, then ozone—to achieve richer vintage looks while avoiding fabric strength damage.
Ozone washing is key to water saving and carbon reduction. Ozone gas oxidizes indigo in a closed drum to achieve fading and bleaching, using only 10%-20% of the water required by traditional processes, with no sodium hypochlorite. In AW26/27, ozone equipment penetration in Humen is expected to exceed 60%, and large washing plants in Xintang have made it standard. Ozone-treated denim feels softer and has more uniform color, especially suitable for vintage blue and gray-blue tones.
Enzyme washing focuses on hand feel and sustainability. Cellulase gently removes surface fuzz to create a worn-in look while reducing pumice use. In AW26/27, neutral cellulase and laccase blends are popular, working at low temperatures and saving over 30% energy. Some Humen factories combine enzyme washing with laser: laser creates coarse textures, enzyme wash provides soft polishing, resulting in a finished product with both dimension and comfort. Export-oriented enterprises in Xintang prefer enzyme washing to comply with EU carbon tariffs and chemical restrictions.
The synergy of these three processes is redefining the "green standard" for denim washing. Laser handles creativity and efficiency, ozone handles water saving and bleaching, and enzymes handle hand feel and biodegradability. AW26/27 denim collections will feature more refined vintage styles—"distressed but not destroyed"—with more natural wash marks and richer color layers.
Industry Impact
The denim industry belts of Humen and Xintang are undergoing a new round of reshuffling due to eco-friendly washing technologies. Small washing plants unable to invest in laser and ozone equipment will face order loss, while early adopters gain favor from international brands. In AW26/27, the "Green Washing Park" promoted by the Humen government has attracted multiple enterprises, centralizing wastewater and ozone tail gas treatment to reduce individual compliance costs.
On the export front, the EU's Ecodesign for Sustainable Products Regulation and Carbon Border Adjustment Mechanism impose strict requirements on chemical use and carbon footprint in denim washing. Ozone and enzyme washing, due to water and carbon savings, are becoming a "passport" for exports to the EU. Xintang exporters report that denim items using ozone washing can reduce carbon footprint by over 40%, allowing them to negotiate a 5%-10% green premium.
On the design side, laser engraving frees designers from the randomness of traditional washing. Digital pattern libraries enable rapid sampling, shortening the design-to-shelf cycle. In AW26/27, Humen design studios have launched combined "laser + ozone + enzyme" solutions, allowing clients to select textures, fade levels, and hand feel online for flexible customization.
In the supply chain, the washing revolution is driving supporting industries. Laser equipment makers, ozone generator manufacturers, and enzyme suppliers are setting up service centers in Humen and Xintang. In AW26/27, local enzyme suppliers can provide low-temperature high-efficiency blends at 20%-30% lower prices than imports, further lowering the threshold for factory transformation.
However, challenges remain. Laser engraving may damage fabric strength, improper ozone concentration can cause over-fading, and enzyme washing is sensitive to pH and temperature. Factories need standardized operating procedures and enhanced employee training. In AW26/27, industry associations in Humen and Xintang plan to launch washing process certifications to drive overall upgrading of the industry belt.
