1. Environmental issues of traditional polyester fiber
Polyester fiber is a petroleum-derived synthetic fiber, and its production process involves high energy consumption and high carbon emissions. Studies have shown that the production stage of polyester fiber is the most environmentally impactful link in its life cycle, which consumes a lot of energy and water resources. Polyester fiber releases microplastics during the washing process, causing pollution to water bodies and ecosystems. Although polyester fiber has advantages such as durability and wrinkle resistance, the environmental burden of its production and disposal stages makes it an important issue that needs to be addressed in the field of sustainable fashion.
2. Innovative materials for sustainable development
In order to address the environmental problems of traditional polyester fiber, the textile industry is exploring a variety of sustainable alternatives:
Recycled polyester fiber (rPET)
Recycled polyester fiber is a yarn made by recycling discarded plastic bottles (such as PET bottles). This material not only reduces dependence on virgin petroleum resources, but also effectively reduces the accumulation of plastic waste. Each ton of recycled PET fiber is equivalent to reducing 4.2 tons of carbon dioxide emissions, 0.036 tons of oil and 6.2 tons of water resources. The use of recycled polyester fibers in clothing has gradually become popular, such as Comfortemp Tencel and Comfortemp Fiberball Pads. These materials are not only biodegradable, but also significantly reduce carbon footprint.
Bio-based and degradable materials
Bio-based materials such as Tencel and bamboo fiber are favored because of their natural origin and degradability. These materials have less impact on the environment during production and can be naturally decomposed after use, reducing the burden on the environment. Comfortemp Tencel is the first 100% biodegradable Interlining material on the market, and its production process does not produce any waste at all.
Low-impact dyeing technology
In the production of Interlining Polyester Fabric, the application of low-impact dyeing technology is also gradually increasing. This technology further reduces the environmental burden of the production process by reducing the use of dyes and energy.
3. The development trend of lightweight and multifunctionality
With the dual demand of consumers for environmental protection and comfort, Interlining materials are moving towards lightweight and multifunctionality:
Lightweight Interlining
Lightweight Interlining materials can reduce the overall weight of clothing and improve wearing comfort. Polyester Interlining coated with hot-melt adhesive can be fused at low temperatures, saving energy. This material also has good elasticity and wrinkle resistance, making it suitable for sportswear and daily wear.
Multifunctional Interlining
Modern Interlining materials not only focus on environmental protection, but also emphasize functionality. Some Interlining materials have antibacterial, antistatic or waterproof properties, which can be achieved by adding special coatings or fibers. Some new Interlining materials are also heat-sensitive and can adjust their performance according to temperature changes.
4. Future Prospects and Challenges
Although sustainable Interlining materials have made some progress, they still face some challenges:
Cost issues
Eco-friendly materials such as recycled polyester fibers and bio-based materials are usually more expensive than traditional materials. This makes it difficult for some companies to promote these new materials on a large scale.
Technical limitations
At present, some sustainable materials still cannot completely replace traditional materials in terms of performance. Recycled polyester fibers may have quality problems in some cases.
Consumer awareness
Although more and more consumers are paying attention to environmentally friendly products, some consumers still have limited awareness of sustainable materials. Raising public awareness of sustainable fashion remains an important task.
