The Polyester Non-woven Fabric segmentation by application is dominated by five primary end‑uses. Medical (surgical gowns, drapes, masks) accounts for roughly 30 % of total revenue, driven by sustained demand for disposable protective equipment and stringent regulatory standards. Hygiene products such as diapers, sanitary napkins, and adult incontinence pads contribute about 25 %, reflecting demographic shifts and rising consumer awareness of skin‑friendly materials. Construction applications—including roofing membranes, insulation boards, and geotextiles—represent 20 % of the market, benefiting from growth in residential and commercial projects and the material’s resistance to moisture and chemicals. Automotive uses, primarily in cabin air filters, sound‑deadening layers, and interior trims, hold a 15 % share, propelled by lightweighting trends and stricter emissions regulations. Finally, Agriculture (greenhouse covers, mulch films, weed control fabrics) makes up the remaining 10 %, where durability and permeability are key value drivers. Collectively, these application segments define the overall market size by allocating demand across distinct industry verticals.
