Against the backdrop of global resource recycling and environmental awareness awakening, RPET (recycled polyethylene terephthalate), as an environmentally friendly material that recycles PET waste plastics, is becoming a revolutionary force in the materials field. The combination of it with spunbond non-woven fabric and Lixin fabric not only endows traditional materials with new performance advantages, but also promotes the industry to move towards green and sustainable direction.

1、Application and advantages of RPET in spunbond nonwoven fabric
（1） Integration and innovation of production processes

Spunbond non-woven fabric is mainly made of polyester and polypropylene as raw materials, and is made by polymer extrusion, stretching into silk, and mesh reinforcement. When RPET is integrated into the production of spunbond non-woven fabric, the recycled PET plastic bottles need to be sorted, cleaned, crushed, melted and granulated before being processed into recycled polyester chips. After mixing these slices with native polyester raw materials in proportion, they enter the spinning process and undergo high-temperature melting, extrusion, and stretching to form continuous filaments. Finally, they are laid and reinforced into non-woven fabric. This process adjustment does not require large-scale equipment modification, which not only retains the original production efficiency of spunbond non-woven fabric, but also achieves the green upgrade of raw materials.

（2） Dual improvement of performance and environmental protection
The addition of RPET adds an environmental label to spunbond nonwoven fabrics while maintaining high strength, aging resistance, and other characteristics. In the packaging field, clothing dust-proof bags and express packaging bags made of RPET spunbond non-woven fabric, with their good toughness and breathability, can not only protect items, but also meet consumers' pursuit of green consumption due to their recyclability. For example, after a certain e-commerce platform adopted RPET spunbond non-woven fabric packaging, consumer environmental satisfaction increased by 20%, and the return rate decreased by 15% due to packaging damage issues. In addition, the recycling of RPET reduces reliance on petroleum based polyester raw materials. It is estimated that for every ton of RPET used, approximately 3.2 tons of carbon dioxide emissions can be reduced, significantly reducing the carbon footprint of the production process.

（3） Application scenario expansion
RPET spunbond nonwoven fabric has also shown potential in the agricultural and industrial fields. In agriculture, its breathable and permeable properties are suitable for crop seedling substrates and plant cold resistant fabrics; In industry, anti-static packaging for electronic components and soundproofing and insulation materials for automotive interiors can be produced. Taking automotive interiors as an example, the sound absorption performance of RPET spunbond non-woven fabric is comparable to that of native materials, but the production cost is reduced by 12%, and it is easier to pass the environmental supply chain audit of automotive companies.

2、 Application and advantages of RPET in Lixin fabric
（1） Core raw materials lay the foundation for environmental protection genes
80% -95% of Lixinbu's raw materials are recycled polyester, and RPET is its core source. During the production process, RPET is spun into polyester short fibers and long fibers, which are reinforced into Lixin fabric through a warp knitted coil structure. High quality RPET raw materials ensure uniform fibers and minimal impurities, giving Lixin fabric high strength and low pilling characteristics. For example, Lixin cloth produced using food grade recycled PET bottles can directly contact the skin and is commonly used as an inner lining for infant clothing. Its safety is no different from that of native materials.

（2） Performance optimization meets diverse needs
RPET endows Lixinbu with outstanding physical properties. Its longitudinal tensile strength is 30% higher than that of ordinary non-woven fabric, and it is not easily deformed even when loaded with heavy objects in luggage production; The waterproof treated Lixin fabric can be used as outdoor tent fabric and remains dry even after 24 hours of rain testing. In terms of chemical corrosion resistance, the chemical stability of RPET makes Lixinbu perform well in cleaning product packaging, laboratory protective materials, and other scenarios. In addition, the regenerative properties of RPET have enabled Lixinbu to obtain GRS certification, making it a preferred choice for procurement in the European and American markets.
（3） Deepening and expanding application fields
In the home textile industry, RPET Lixin fabric is used to make curtains and sofa covers, and its breathable and skin friendly properties enhance home comfort; In the medical field, Lixin cloth that meets non-toxic and environmentally friendly standards can be used to make surgical sheets and medical bed sheets. After use, the carbon emissions from incineration treatment are reduced by 18% compared to traditional materials. Fashion brands have also adopted RPET Lixin fabric to design environmentally friendly clothing, such as the RPET Lixin fabric denim jacket launched by a fast fashion brand, which sold out within two weeks after its launch due to its combination of retro texture and sustainable concept.

3、 The Industry Value and Future Prospects of RPET Applications
The combination of RPET with spunbond non-woven fabric and Lixin fabric not only enhances product performance and market competitiveness, but also builds a closed-loop industrial chain of "recycling regeneration application". With the advancement of technology, the purity and quality of RPET will be further improved, and the fusion process with materials will also be more efficient. In the future, with the advancement of the global "dual carbon" target and the increasing environmental awareness of consumers, the application of RPET in the non-woven fabric field will continue to deepen, becoming a key force in promoting the green transformation of the materials industry.
