Choosing fabric for the home is rarely just about colour or pattern. Curtains, upholstery and soft furnishings all shape how a room feels, but they also affect comfort, durability and the wider environmental footprint of the materials brought into the house. For many people, the question is no longer simply which fabric looks best, but whether natural or synthetic fabrics are the better choice for interiors.
Synthetic fibres such as polyester, acrylic and nylon remain common in furnishing fabrics because they can be inexpensive, stable and easy to care for. But they also come with environmental costs that are becoming harder to ignore.
What is the difference between natural and synthetic fabrics?
Natural fabrics are made from fibres that come from plant or animal sources, including hemp, linen, cotton, wool and silk. Synthetic fabrics are made from man-made polymers, usually derived from fossil fuels. In interiors, both can appear as pure fabrics or as blends.
Many furnishing textiles mix natural fibres with polyester, acrylic or nylon to alter softness, crease resistance, abrasion performance or price point. That is one reason the distinction matters: a fabric may look natural on the surface while still containing a significant plastic content.
Why synthetic blends are so common in interiors
Synthetic fibres are widely used in furnishing fabrics because they can add consistency, reduce cost and improve certain performance characteristics. A supplier may add polyester to help stabilise a weave, acrylic to imitate wool-like softness, or nylon to increase abrasion resistance. From a purely commercial point of view, this can make sense. But it also means many interior fabrics are partly plastic, even when marketed with the language of texture, comfort or practicality.
The convenience is real, but so is the trade-off. For customers trying to reduce plastic in the home and make more considered material choices, fibre content matters.
Why synthetic fabrics are a problem for the environment
The environmental case against synthetic-heavy interior fabrics is strong. Because these fibres are typically fossil-fuel based, their production is tied to resource extraction, energy use and greenhouse-gas emissions. The European Environment Agency notes that synthetic fibres, especially nylon and acrylic, generally have a higher climate impact than many natural fibres because of their fossil origin and the energy required to produce them. It also identifies synthetic textiles as an important source of microplastic pollution.
That matters in interiors too. Furnishing fabrics are not only part of a product story at the point of manufacture; they remain in the home for years, where use, abrasion, cleaning and eventual disposal all form part of their impact. Synthetic fibres can fragment through wear and persist in the environment because plastics do not readily biodegrade. In other words, the issue does not end when the fabric leaves the mill.
Are synthetic fabrics worse for the home environment?
This needs a balanced answer. It would be too simplistic to say that every synthetic fabric is automatically unsafe and every natural fabric is automatically healthy. But indoor air quality does matter, and official guidance recognises that indoor environments can contain pollutants including VOCs and formaldehyde from furnishings, consumer products and building materials. Choosing more natural, lower-plastic and less heavily treated materials can therefore be one sensible part of creating a calmer, lower-chemical home environment.
Why natural fabrics are often the better choice
Natural fabrics usually offer advantages that go beyond sustainability language. They tend to bring greater depth, breathability and tactile interest to a room. They often feel less flat and less overtly manufactured than synthetic-rich fabrics, which is one reason they are so valued in relaxed, understated interiors.
They also align more closely with a growing desire for homes built around longevity, material honesty and reduced plastic use. Natural fibres are not impact-free, but they are often the more responsible choice when selected carefully and matched to the right end use.
For Leaf & Loom, hemp remains the hero fibre. Hemp offers strength, texture, breathability and durability in a way that suits many interior applications beautifully. It can be woven into fabrics with body, drape and character, making it especially compelling for curtains, upholstery and soft furnishings.

Which is better for curtains and upholstery?
For curtains, natural fabrics often bring the most visual reward. Hemp and linen can filter light beautifully, create a softer atmosphere and give folds a more relaxed, elegant character. Synthetic-rich curtains may offer easy care, but they can also feel shinier, flatter or less breathable depending on the weave.
For upholstery, the answer depends on construction as much as fibre. Some synthetic blends are used to boost abrasion performance, but that does not always mean they are the best long-term choice aesthetically or environmentally. A well-made natural fabric with the right weight, weave and durability can be the better option, especially where texture, longevity and lower plastic content matter.

Are blends always the wrong choice?
Not necessarily. Some blends can be useful, especially where they improve softness, stability or performance. But in sustainability terms, it is still worth being honest about what a blend means. Once synthetic fibres are introduced, the fabric is no longer a purely natural option.
For customers actively trying to reduce plastic in the home, that matters. In many cases, the better route is to choose a fabric that relies on fibre quality, thoughtful weaving and appropriate end use rather than plastic content to achieve performance.
Choosing more sustainably
The more sustainable choice is usually the fabric that combines renewable fibre content, suitability for purpose, durability and lower dependence on plastic. That is better for the look and feel of the home, often better for reducing synthetic content in everyday surroundings, and better for the planet than treating petroleum-based textiles as the default.
If you are comparing options, ask not only how a fabric looks today, but what it is made from, how it will age, and what kind of material story you want your home to tell.
If you are trying to reduce synthetic content in the home, natural fabrics are often the most satisfying place to start.
