Millions of plastic bottles and plastic waste are disposed of every day. The waste not only lies in the dumping grounds but also intervenes with the soil quality, reaches the water resources, and emits harmful gases in the long run.

Thus, plastic waste pollutes all natural sources to the extent that even living beings are affected. Plastic waste recycling has emerged to be a saviour in such a situation.

How Recycling Technologies Enable Diverse Industries

Recycling technologies help transform waste into useful products, of which recycled polyester staple fibre is in demand. Industries like upholstery, clothing, insulation, and automotive consume recycled yarns.

Some major features of recycled polyester include high abrasion resistance, high tensile strength, dimensional stability and more.

Understanding the Tensile Strength of Recycled Polyester Staple Fiber (RPSF)

The tensile strength is the force required to elongate (stretch) and break a fibre. The higher the tensile strength, the higher the product quality for consumers. This can be applied to nonwoven fabrics, sheeting, and woven fabrics.

The high tensile strength of recycled polyester makes it a sustainable choice for the future. The measuring unit for this force is pounds, kilogram-force or, more commonly, Newtons.

How Tensile Strength Impacts Technology and Use of Waste Material

Tensile strength directly depends on the quality of yarn produced, the thread counts, and the material used in the process. In the case of recycled polyester, it is related to the technology and waste material used.

The best RPSF Manufacturer in India uses the latest machinery and keeps quality checks at each level to ensure that the polyester yarn is high quality and per global standards.

The high tensile strength attracts automobile, insulation, and clothing industries to better leverage Recycled Polyester Staple Fibre (RPSF) as raw material.

Key Facts about Fabric Tensile Strength of RPSF

Below are some facts related to fabrics and their strengths consumers should know:

o Synthetic or manmade fibres have higher tensile strengths compared to natural fibres. This is one reason polyester is grabbing the largest share of the clothing industry. But now recycled polyester staple fiber is set to take over virgin polyester since it offers similar features with less environmental impact.

o Fabrics with fine-quality and longer-staple fibers have better tensile strength when compared to short and coarse types.

o Tensile strength is calculated in the weft and warp direction. When comparing two fabrics with the same weft and warp count, one with more threads per square inch will have more tensile strength.

A reliable RPSF manufacturer in Gujarat, Maharashtra, Karnataka, or any other state would ensure that it maintains the tensile strength of the recycled polyester yarn so that the products are of high quality as well.

Methods for Testing Tensile Strength of Recycled Polyester Staple Fiber (RPSF)

The best RPSF manufacturer in India regularly tests the fiber produced in recycling plants. PET bottles are obtained from waste collectors and have a lot of debris, foreign material, and non-recyclable components.

Several samples from the same RPSF yarn are taken to have accurate results. Such components must be discarded to ensure they do not affect the process and yarn quality. There are two methods for testing the tensile strength, and here are the details:

Strip test: In this test, a bundle of fiber is put between two gripping movable jaws and stretched until the fiber breaks. A standard-length specimen is taken along with the gripping margin. The breaking load of all specimens is noted, and calculations are made based on the initial and last load readings. Usually, specimens from both weft and warp directions are taken using the magnifying glass to ensure accurate results.

Grab test: A 6”x4” specimen is taken in this method. However, only one inch of it is subjected to stretching by the gripping jaws. The testing process is the same as the strip test.

Key Takeaways

The government checks the procedures and testing followed by Recycled Polyester Staple Fiber (RPSF) manufacturers in Gujarat, Punjab, Tamil Nādu, and other states that have recycling plants.

JB Ecotex as a leading RPSF manufacturer, follows the guidelines and maintains the quality of recycled polyester staple fiber supplied to its clients. The standardization results in better product offerings to end-consumers and helps consume an increasing quantity of plastic waste.
