A Guide to Textile Testing Methods

Introduction

Even though they are rarely considered, textiles are a fundamental a regular aspect of our life. They are used in everything from clothing to automobile upholstery to rugs. While suitable textiles may go unnoticed, inferior textiles are immediately noticeable. A cloth that only lasts through one or two washing before breaking apart or a hand napkin that leaks colour whilst in operation can both negatively impact our experience with fabric goods. By creating a set of requirements that textiles must meet, textile testing aims to counteract these drawbacks. This post will define textile testing, discuss the organizations overseeing the textile industry, and go through some standard textile testing methods.

What Does Textile Testing Mean?

Before a textile product is made available on the market, it may undergo various quality tests, collectively referred to as textile testing. As consumers, we desire to have faith in the fabric used to make our clothing and other goods. We desire them to be soft when we use it, to maintain their vibrant colour, to not shred or degrade, and to be free of any toxins that may not be suitable for human interaction. Whenever textiles are utilised, for instance when creating industrial products or flame-resistant safety equipment, we also need to ensure that the fabric will perform as anticipated and serve the original goal. We can ensure that our items won’t affect us by evaluating the fabrics.  We will maintain the desired chemical and physical properties.

Which Organizations Regulate Textile Testing?

The methods used to produce textiles frequently include a variety of locations and countries. Standardization and excellent quality practices are intended to be introduced to the textile sector by ISO, the ASTM, and various regional professional regulatory organizations. No matter where a product is created, these organizations aim to guarantee an acceptable end result. Governmental organizations may, in some situations, enforce regulatory standards for textiles. The Federal Trade Commission (FTC) in America controls characteristics of fabric manufacturing, including statements about the environment and clothing labels.

Standards of ASTM and ISO Textile Testing

Both ASTM and ISO International are organizations that assemble committee-based, optional norms. These professional committees are often made up of people who operate in the relevant industry. The global committees for textiles of ASTM and ISO collaborate to develop textile standards and provide recommendations for streamlining production techniques. The standards have been put together and might be published on the internet or in an actual book that can be bought. Although adhering to the recommendations of these organizations is not required, it might assist textile manufacturers in ensuring uniform quality and developing a group of procedures for standard operating.

Textile Testing Methods

According to the application, there are numerous ways to conduct textile tests since there is a multiple fabric testing to fulfil different regulatory requirements. However, we may categorize textile testing methods into some general groups:

Physical Testing

Quality experts will look at a fabric’s physical properties when performing physical testing on textiles. This physical testing aims to get a textile sample should provide as much technical data as feasible so that buyers may be sure in its constitution and that it will be suitable for its layout. Throughout physical testing, textiles are recognised and assessed for a number of characteristics, such as rigidity, heaviness, coatings, cloth number for woven materials, measurement of both bundled and disconnected fibre length, and many more. 

Mechanical Testing

The phrase “mechanical testing of fabrics” describes a variety of tests used to determine the tensile power and endurance of a cloth. It’s important since, as consumers, we desire to be sure that the fabrics we purchase will withstand everyday use and deterioration for the length of their specified lifespan. The below are a few of the most popular tensile testing for fabrics, although there are many others: 

• Tensile Testing: Defines the greatest force that a fabric can withstand when it is kept under constant, controlled tension.  In this test, a fabric is continuously pulled from various angles until it ruptures using specialized tensile testing equipment. Tensile testing aids in establishing the breaking point of the textile, how much it can be stretched before losing its shape, how strong it is against ruptures, and much more.

• Abrasion Testing: Tests for a fabric’s susceptibility to superficial damage and wear using continuous rubbing are known as abrasion tests. The two primary abrasion testing procedures are Martindale and Wyzenbeek. During Wyzenbeek inspection, material is dragged tightly onto a device and continuously scraped back and forth using an approved abrasive material. ‘Double rubs’ are counted up until two fabric splits or apparent wear happen. In Martindale examination, a bit of cotton wool is used as the abrasive substance, and a bit of cloth is placed and scratched in the pattern of an eight. Despite the fact that the two assessments are related, a high or low result on one exam does not necessarily correspond to a corresponding score on the other one.

• Pilling Testing: Determines how well a fabric can withstand pilling. Pilling is a tendency for a material to form little, fluffy pellets of loose materials on its top that is commonly brought on by friction and wear over period. The ICI Box Pilling Test is used by quality testers to evaluate a fabric’s tendency to pill.

Textile materials are attached to specialised polyurethane tubing for this examination. Following certain rotations in a pilling box with these materials, any pill production is then identified. The Martindale technique could also be employed in some cases to test for pilling. 

Chemical Testing

Lab testing of fabrics has as one of its key goals ensuring that a fabric piece is free of harmful substances that may not be appropriate for human contact. To ensure a fabric is healthy, laboratory testing for lead as well as other contaminants, phthalates, dangerous colours, and other compounds may be utilised. To determine a fabric’s pH and colour fastness in response to conditions like light, heat, sweat, or fluoridation, biochemical analysis of textile materials can be done, in addition to keeping us safe. This is particularly important for fabrics used in sporting clothing to provide the best possible fit and body performance during physical exercise. 

Conclusion

The discipline of textile testing covers a wide range of textile production features. Following best practices and being aware of the textile properties can aid in producing goods of high quality that are both aesthetically beautiful and useful.
