Traditional curtain fabrics — woven textiles made from yarn — have long dominated the window treatment industry. However, the rising demand for cost-efficient, high-volume, print-friendly, and dimensionally stable curtain substrates has pushed nonwoven materials to the forefront of curtain manufacturing. Unlike woven or knitted fabrics, nonwoven fabrics are engineered directly from fiber webs, with fibers bonded through mechanical, thermal, or chemical means — bypassing the spinning and weaving process altogether.
For curtain applications specifically, the spunlace (hydroentanglement) process using 100% polyester fibers has proven to be the most commercially viable and technically superior approach. The resulting material offers an exceptional combination of drape, printability, dimensional stability, and durability — qualities that are essential for both home furnishing and commercial window treatment markets.
At Zhejiang Aojia Nonwoven Technology Co., Ltd., the curtain substrate product is part of the broader Home Improvement Series, which also includes nonwoven wall cloth — reflecting the growing integration of advanced nonwovens into residential and commercial interior applications.
The defining manufacturing technology behind Aojia's curtain fabric is the spunlace process, also known as hydroentanglement. This process is fundamentally different from thermal bonding (heat-fusion) or chemical bonding (adhesive-based) nonwoven production methods, and its distinct mechanism directly determines the superior performance of the resulting curtain substrate.
100% polyester staple fibers are opened, blended, and carded into a uniform fiber web. Consistent fiber distribution at this stage is critical for achieving even weight and density across the full fabric width (up to 3,200 mm).
High-pressure water jets (typically 30–200 bar) are directed through fine nozzles onto the moving fiber web. The water jets cause the fibers to mechanically interlock and entangle with one another — creating a cohesive, bonded structure without adhesives or binders.
The entangled wet web passes through suction and drying systems to remove water. This stage also consolidates the structure and establishes the fabric's baseline weight (gsm) and tensile characteristics.
Thesizing processis Aojia's key value-added step for the curtain substrate. A sizing agent is applied to the fabric surface, which: (a) enhances dimensional stability by restricting fiber movement, (b) creates a crisp, structured hand-feel ideal for curtain drape, and (c) forms a smooth, sealed surface that dramatically improves printability and ink adhesion.
The finished fabric is slit to specified widths (400–3,200 mm), wound into rolls, and subjected to quality inspection for weight uniformity, tensile strength, dimensional stability, and surface consistency before dispatch.

What makes spunlace nonwoven specifically outperform traditional woven curtain base fabrics across the critical criteria that matter to manufacturers?
The combination of polyester fiber's natural resilience and the sizing finishing process creates a fabric that falls elegantly when hung, yet returns to its original dimensions after handling, washing, or high-humidity exposure. This is critical for curtains used in tropical climates or high-moisture environments such as bathrooms and kitchens.
The sized surface creates an ideal ink-receiving layer for both digital inkjet printing and traditional rotary/flat screen printing. The sealed, uniform surface minimizes ink bleed, maximizes color gamut, and enables finer detail resolution — essential for producing photo-realistic curtain patterns at commercial volumes.
100% polyester spunlace is inherently resistant to deformation under load, UV exposure, and repeated wash cycles. The hydroentangled fiber structure resists pilling and fraying along cut edges, reducing post-production finishing requirements for curtain manufacturers.
Nonwoven production bypasses the spinning and weaving stages required for conventional textiles, reducing energy consumption and production time per meter. Combined with wide-width availability (up to 3,200 mm), this delivers a significant cost-per-panel advantage for high-volume curtain printing operations.

Perhaps the most commercially impactful technical property of spunlace nonwoven curtain fabric is its superior printability. In the modern curtain manufacturing supply chain, the vast majority of decorative value is added through surface printing — whether by digital inkjet systems, flat-bed screen printers, or rotary screen printers. The substrate's interaction with printing systems directly determines final product quality.
The sizing finish applied during Aojia's production process seals the surface of the nonwoven fabric, reducing the surface's porosity to a controlled level. This creates several critical printing advantages:
Reduced ink bleed: Without sizing, ink droplets (especially in digital inkjet systems using water-based pigment inks) penetrate too deeply into the fiber matrix, causing feathering and reduced sharpness. The sized surface confines ink spread to the top layer, enabling sharper edge definition and finer pattern detail.
Improved color density: When ink is absorbed deeply into a fabric rather than sitting near the surface, light reflectance decreases and color appears duller. The sized surface keeps pigments in the optimal light-reflection zone, resulting in more vibrant, saturated colors — a key quality benchmark in decorative curtain production.
Consistent print registration: Dimensional stability from sizing means the fabric does not stretch or distort under the tension of printing machine transport systems, which is critical for multi-pass printing or patterns requiring precise registration across widths up to 3,200 mm.
Aojia's curtain substrate has been engineered to perform across the primary printing technologies used in curtain manufacturing globally: digital reactive inkjet printing, digital pigment inkjet printing, flat-bed screen printing with reactive or pigment dyes, and rotary screen printing for high-volume runs. This cross-technology compatibility gives downstream manufacturers flexibility in production line selection without material changes.
Environmental performance is an increasingly critical criterion in the home furnishings procurement cycle, particularly for buyers in European and North American markets. The sustainability profile of spunlace polyester nonwoven curtain fabric involves both advantages and ongoing industry challenges that informed buyers should understand.
No adhesives or chemical binders: Spunlace bonding is a purely mechanical process using water jets. This eliminates the formaldehyde-containing binders used in many thermally or chemically bonded nonwovens, reducing both occupational exposure risks during manufacturing and off-gassing in finished curtain products — particularly relevant for residential and hospitality applications.
Polyester recyclability: 100% polyester composition (no fiber blends) simplifies end-of-life recycling, as mono-material fabrics are more amenable to mechanical and chemical recycling streams than multi-fiber blends.
Long service life: The durability and shape-retention characteristics of spunlace polyester nonwoven extend curtain product lifespan compared to lower-quality woven alternatives, reducing replacement frequency and associated resource consumption.
Through Aojia's customization capabilities, curtain substrates can be produced with additional functional properties including flame retardancy (critical for commercial and hospitality installations under fire safety codes), anti-UV treatment (for sun-facing windows), anti-static finishes (relevant in low-humidity environments), and anti-bacterial properties (increasingly specified for healthcare facility window treatments). These finishes can be incorporated during the sizing stage or applied as post-process treatments.
The primary volume application for Aojia's curtain substrate is as the base fabric for printed residential window curtains. The combination of light weight (as low as 32 gsm), excellent drape, and print-ready surface makes it ideal for producing the patterned, colored curtains sold through furniture retailers, online home goods platforms, and home furnishing chains globally. The fabric's dimensional stability also makes it suitable for curtains used in smaller living spaces where exact sizing is critical.
Hotels and commercial office buildings represent a large-volume, specification-driven segment for nonwoven curtain fabric. In these applications, consistent appearance across hundreds or thousands of identical panels, fire safety compliance, and durability through professional laundering cycles are paramount. Aojia's curtain nonwoven, particularly in heavier weights (50–60 gsm) with flame-retardant treatment, is well-suited to these demanding commercial use cases.
In open-plan commercial environments and temporary exhibition spaces, wide-width nonwoven fabrics are increasingly used as printed space dividers — an application that leverages both the material's large available width (up to 3,200 mm) and its printability for branding, wayfinding, and aesthetic purposes. The structural integrity provided by the sizing finish ensures panels hang straight without bunching or sagging.
Professional photography studios and exhibition designers have adopted wide-format nonwoven curtain substrates as printed backdrop materials. The fabric's matte, non-reflective surface finish reduces unwanted light bounce, while its printability enables large-format, high-resolution image reproduction. The lightweight nature of the material also simplifies installation and transport compared to traditional canvas or vinyl backdrops.

Several converging macroeconomic and technological trends are accelerating the shift toward nonwoven substrates in the global curtain manufacturing industry:
The proliferation of digital inkjet printing technology has enabled curtain manufacturers and retailers to offer custom-printed curtains on demand — down to individual consumer orders. This model requires substrates with exceptional printability and dimensional stability, qualities that spunlace nonwoven delivers consistently and at scale. Traditional woven fabrics with irregular weave structures are increasingly ill-suited to the precision demands of digital print-on-demand.
Online retail channels for home furnishings — where product photography and digitally reproduced color accuracy are paramount sales tools — have created strong pull for high-quality printed curtains. The ability to produce vibrant, photographically sharp curtain patterns at scale on nonwoven substrates directly supports this channel's growth.
Hotels, offices, and commercial spaces are refreshing interior designs at increasingly frequent intervals to remain competitive. The cost efficiency and large-width availability of nonwoven curtain fabric makes it the preferred substrate for high-volume commercial refurbishment projects, where per-panel material cost is a primary procurement criterion.
Growing awareness of indoor air quality, fire safety regulations, and antimicrobial requirements across residential and commercial sectors is driving demand for functionally-finished curtain substrates. Manufacturers able to offer customized flame-retardant, anti-bacterial, or anti-UV treatments on nonwoven curtain fabric — as Aojia does — are positioned to capture premium-specification market segments that woven fabric suppliers struggle to serve efficiently.
