Technical Qualities that Turn Recycled Polyester Staple Fiber (RPSF) Effective

May 01, 2023

Recycled fibres have become immensely popular in the apparel industry, of which recycled polyester staple fiber has the maximum share. Sustainable fiber helps achieve a circular economy in plastic waste management. Waste PET bottles pose a severe threat to the environment since they are non-biodegradable.

Thus, manufacturers and brands are now recycling the waste and transforming it to textile-grade RPSF. The technical properties of the fiber obtained from the best RPSF manufacturer in India make it an excellent choice for upholstery, clothing, decor, and more.

Sustainability of Recycled Polyester Staple Fiber (RPSF) in India

The advent of recycled polyester staple fiber is an alternative to virgin polyester. Virgin polyester is produced by initiating chemical reactions in petroleum. As demand increased, manufacturers realized that using a non-renewable resource would lead to issues in the future.

On the other hand, managing ever-increasing plastic waste in landfills also poses a challenge. Thus, recycled PET fiber has dual benefits consuming PET waste bottles and saving petroleum. Also, manufacturing recycled fiber consumed less energy, low water consumption, and emitted lower levels of CO2 compared to virgin polyester.

Today, recycled polyester staple fiber export is a huge industry in India and is believed to grow in the future.

Technical Properties of Recycled Polyester Staple Fiber (RPSF)

Recycled polyester staple fiber manufacturers in India follow the government guidelines and ensure that the output quality meets world standards. Some major technical properties of the fiber are:

1. Crystallinity and amorphous

A fiber has different structures like amorphous and crystallinity. While amorphous is the region without any order of chain molecules, crystallinity is defined as the regular arrangement of molecular chains. The crystallinity also impacts the tenacity and strength of the fiber.

Recycled polyester staple fiber suppliers ensure that the fiber has higher crystallinity. Usually, the percentage of crystallinity and amorphous is believed to be around 28% and 62%, respectively.

2. Glass transition temperature

Recycled polyester obtained from a technologically advanced PET fiber plant in India has a high glass transition temperature, around 87 °C, higher than virgin polyester. This scenario is defined as the temperature at which the polymer changes from a glassy, rigid state to a rubbery and flexible form. This property renders recycled polyester dimensional stable and has high-heat resistance.

3. Tensile strength

The recycled polyester obtained from a reliable RPSF manufacturer in Gujarat has high tensile strength, meaning that the fiber has high abrasion and impact resistance. High-quality recycled PET flakes in Surat are used across various industries as raw manufacturing materials.

4. Moisture content

Recycled Polyester Staple Fiber manufacturers in India offer fiber that absorbs less moisture. This is a great feature that clothing companies, especially athleisure brands, want. This also means that the clothes made with this fiber are lightweight and quick-dry.

5. Fiber color dyeing properties

Recycled polyester staple fiber in India can be easily dyed. Also, they usually don’t bleed color on use like cotton.

Growing Demand for Recycled PET Fiber

Recycled polyester has become popular worldwide and will soon replace virgin polyester completely. In India, recycled polyester staple fiber suppliers maintain quality and adopt the best equipment to improve productivity. This has led to expanding the recycled polyester staple fiber export. This is also seen as an economic opportunity to help India grow while managing its plastic waste.

The Indian government has been encouraging companies to set up PET fiber plants in India to implement EPR successfully. RPSF manufacturers in Gujarat, Maharashtra, Delhi, and several other states contribute and recycle a million tonnes of plastic annually.
