Fire-resistant recycled fiber is a new type of fiber that has both environmentally friendly recycling and flame-retardant and fire-proof functions. It not only conforms to the green and low-carbon development trend, but also meets safety protection requirements. It is increasingly used in textiles, home furnishings, tooling, public facilities and other fields. According to the source of raw materials, flame retardant methods and structural characteristics, fire-resistant recycled fibers can be divided into multiple categories. The characteristics of different types are obviously different, and the applicable scenarios and selection ideas are also different.

Fire-resistant recycled fibers are mainly divided into three categories based on raw materials and regeneration paths. The first type is regenerated polyester-based fire-retardant fiber, which is made from recycled polyester such as recycled bottle flakes and waste textiles through flame-retardant modification of the original solution. It is the fire-retardant regenerated fiber with the largest output and the most widely used currently. The second category is regenerated cellulose-based fire-retardant fiber, which uses regenerated plant-based fibers such as regenerated bamboo fiber, regenerated cotton, viscose, and lyocell as the base material. It obtains fire-retardant properties through flame-retardant finishing or modification. It is skin-friendly, breathable, and more environmentally friendly. The third category is composite regenerated fire-retardant fiber, which is composed of regenerated polyester, regenerated cellulose and flame-retardant components. It takes into account strength, softness and fire-retardant stability. It is mostly used in high-end protective and home textile products.

In terms of common characteristics, the three types of fire-resistant recycled fibers are recyclable, low-emission, environmentally friendly and low-carbon, complying with the requirements of circular economy, and have good flame-retardant effects. They do not prolong flames when exposed to fire, do not drip melt, have low smoke and are non-toxic, and self-extinguishing when removed from fire. In terms of differentiated characteristics, regenerated polyester fire-retardant fiber has high strength, wear resistance, anti-wrinkle, easy processing, and moderate cost; regenerated cellulose fire-retardant fiber is soft to the touch, moisture-absorbent and breathable, close-fitting and comfortable, and is suitable for products that come into contact with the skin; composite regenerated fire-retardant fiber has stronger comprehensive performance, higher fire-resistance level, better water resistance and durability, and can maintain the flame-retardant effect after multiple washings.

Different types of fire-resistant recycled fibers have different application scenarios. Recycled polyester fire-resistant recycled fibers are mostly used in home textiles, curtains, carpets, sofa fabrics, car interiors, office furniture, etc., in scenarios with high requirements for strength, durability and fire safety. Regenerated cellulose fire-resistant regenerated fiber is more suitable for infant products, elderly bedding, home clothes, underwear, medical care products, hotel linens, etc., emphasizing skin-friendly, breathable, safe and environmentally friendly. Composite recycled fire-resistant recycled fibers are mainly used in high-end, high-standard protection fields such as flame-retardant workwear, fire-fighting suit linings, rail transit seat fabrics, aviation interiors, and flame-retardant fabrics in public entertainment venues.

For corporate procurement and product development, the three-step principle can be followed when choosing fire-resistant recycled fibers. First, clarify the fire protection level, select the corresponding flame retardant standard according to the product use, and distinguish the different requirements for household, workwear, and public scenes. Secondly, to match the usage environment, choose durable regenerated polyester fire-retardant fiber for home textile interiors, regenerated cellulose fire-retardant fiber for personal-wear products, and composite regenerated fire-retardant fiber for high-end protection. Finally, considering environmental protection and cost, we give priority to manufacturers with stable sources and can provide recycling certification and flame retardant testing reports to enhance product added value and market competitiveness while ensuring performance.

Overall, fire-resistant recycled fiber has achieved the dual value of “environmental protection + safety", with clear categories, clear characteristics, and segmented scenarios. Enterprises scientifically select products based on product positioning, user groups, fire protection standards and processing techniques, which can not only meet safety regulations, but also conform to green consumption trends and enhance product differentiation advantages.
