Understanding the Value of Testing for Pilling Resistance in Textiles

Published: March 4, 2023

Analysing different aspects of textiles and fabrics to make sure they are high-quality, long-lasting, and secure is known as textile testing. Physical testing and chemical testing are the two subcategories of this testing procedure. To ensure that textiles are secure, long-lasting, and up to the standards needed for their intended use, textile testing is crucial. The different kinds of textile testing, testing methods, the value of textile testing, difficulties in textile testing, and the future of textile testing will all be covered in this blog.

Types of Textile Testing:

Analysing a textile’s physical characteristics, such as its strength, abrasion resistance, pilling resistance, rip resistance, and colorfastness, is known as physical testing. The amount of energy necessary to rip or break the fabric is determined by the strength testing. How well the cloth resists wear and tear is determined by abrasion testing. Testing for pilling resistance determines a fabric’s propensity to create pills. The amount of power needed to tear the fabric is determined by tear resistance testing. Testing for colorfastness determines how well a fabric keeps its colour after being exposed to different factors.

Analyzing a textile’s chemical characteristics, such as fibre identification, chemical composition, flammability, environmental effect, and care labelling, is the subject of chemical testing. The sort of fibre used in the fabric is identified by the fibre. Testing for chemical makeup determines whether dangerous elements like heavy metals, formaldehyde, and pesticides are present. Testing for flammability determines how well a cloth can withstand burning. The effect of the fabric on the atmosphere is investigated through environmental testing. The finest method of fabric maintenance is determined by care labelling testing.

Testing for pilling resistance is a sort of physical examination used to assess a fabric’s resistance to pilling. Piling is the process whereby friction causes tiny fibre balls to develop on the fabric’s surface. The appearance, comfort, and durability of the cloth can all be impacted by pilling. To ensure that their fabrics satisfy the requirements for their intended use, manufacturers must test their fabrics for pilling resistance. We will go over the definition of pilling resistance testing, its significance, the testing procedure, and elements that influence pilling resistance in this blog post.

What is Pilling Resistance Testing?

Testing for pilling resistance is a form of physical examination that determines a fabric’s resistance to pilling. The test entails rubbing the cloth for a predetermined amount of time against an abrasive surface, like a cork or emery wheel. The quantity of pilling is then taken into account when evaluating the fabric. On a scale of 1 to 5, with 1 being the worst and 5 being the best, the fabric is usually rated.

Why is Pilling Resistance Testing Important?

To make sure that their fabrics satisfy the necessary quality standards, manufacturers must test their fabrics for pilling resistance. The appearance, comfort, and durability of the cloth can all be impacted by pilling. Easy-to-pill fabrics might not be ideal for certain uses, such as clothing or furniture, where pilling can be uncomfortable or unsightly. Testing for pilling resistance can assist manufacturers in identifying quality problems early on and improving their manufacturing methods.

Pilling Resistance Testing Process:

In order to evaluate a fabric’s ability to resist pilling, it is rubbed against an abrasive surface for a predetermined amount of time. A Martindale tester is usually used to conduct the test, simulating the rubbing motion that takes place during everyday use. The testing device is used to rub the fabric sample against an abrasive surface for a predetermined number of cycles, usually 100 or 200. The amount of pilling is then used to rate the fabric, with a higher rating showing better pilling resistance.

Factors Affecting Pilling Resistance:

The fibre content, yarn twist, fabric structure, and finishing techniques are just a few of the elements that can impact a fabric’s pilling resistance. Natural fabrics like cotton and wool tend to pill more easily than synthetic fibres like nylon and polyester. Compared to fabrics made from loosely spun yarns or with a low yarn density, fabrics made from tightly twisted yarns or with a high yarn density typically have superior pilling resistance. The resistance to pilling of a cloth can also be impacted by finishing procedures like singeing or shearing.

Textile Testing Procedures:

The collection and preparation of test samples, the choice of tools and equipment, the testing methods, and the analysis and interpretation of data are all steps in the textile testing process. To guarantee accurate results, the sample must be representative of the complete fabric and the preparation procedure must be consistent. Depending on the type of testing needed, different testing equipment is used for textiles. To ascertain the fabric’s quality and safety, testing methods and standards are used that are particular to each test, and the data gathered must be analysed and understood.

Importance of Textile Testing:

Quality control, legal compliance, customer safety, cost efficiency, and environmental sustainability all depend on textile testing. To ensure that the fabric meets the required quality standards, the textile business relies on textile testing. In order to ensure that fabrics are safe for consumers to use, regulatory organisations require textile testing. By detecting quality problems early on, textile testing can also assist producers in cost reduction. Last but not least, textile testing can guarantee that fabrics are produced sustainably, reducing their environmental impact.

Challenges in Textile Testing:

Lack of standardisation, a lack of testing facilities, expensive testing costs, and quickly advancing technology are some of the problems with textile testing. It is challenging to compare test results across different labs due to a lack of standardisation. It may be difficult for manufacturers to obtain testing services due to a lack of testing facilities. For small manufacturers, the expensive expense of testing can be a barrier. It is challenging for testing practises and standards to keep up with technological developments due to how quickly technology is changing.

Future of Textile Testing:

With new trends and technologies, improvements in testing techniques and tools, a greater emphasis on sustainability, and global standardisation initiatives, the future of textile testing is promising. New testing methods will be needed as a result of emerging technologies like 3D printing and nanotechnology, which will affect the textile industry. The accuracy and efficiency of textile testing will continue to be enhanced by improvements in testing methods and tools. Additionally, there will be a stronger stress on lowering the environmental impact of textile production as well as sustainability in textile testing. Last but not least, attempts at international standardisation will aid in ensuring that test results are comparable between laboratories and nations.
