Different kinds of cotton yarns at Thread CollectiveCotton, a versatile and widely used natural fibre, can undergo various treatments to enhance its properties for different applications. One such treatment is mercerisation, which imparts specific characteristics to cotton fibres. This article explores the differences between mercerised and non-mercerised cotton, shedding light on their respective features and applications.History of MercerisationJohn Mercer, a skilled English dye and fabric chemist, started his journey in dyeing at sixteen. He set up a small lab at home, experimenting with colours and mixtures. After a successful dyeing shop venture, Mercer became an apprentice at a print shop. Unfortunately, a spiteful foreman limited his experience, leading him to embrace weaving.Maurice Brassard 8/4 mercerised cotton yarnsRekindling his passion for dyeing and chemistry, Mercer joined the Fort brothers in 1818, excelling as a colour chemist. In 1848, the partnership dissolved, giving Mercer the time and resources to explore textile processing. His groundbreaking experiment in 1850, called mercerisation, involved treating cotton with chemicals, making it stronger, resistant to shrinking, and imbuing it with a lustrous appearance.Although Mercer discovered the process in 1844, it went unnoticed for around forty years. In 1890, Horace Lowe's patent highlighted the application of Mercer's caustic soda process, bringing overnight success and revolutionising the cotton industry with the famous mercerised cotton we know today.Why Do We Mercerise Cotton?Cotton is mercerised to enhance its qualities and make it more suitable for various applications. Here are the primary reasons why we mercerise cotton: Increased Durability: Mercerisation strengthens cotton fibres, enhancing the fabric's overall durability. This is particularly valuable for textiles that must withstand wear and tear, like clothing and home textiles. Shrink Resistance: Mercerised cotton is less prone to shrinking when exposed to washing and drying. This makes mercerised cotton garments more stable in size, providing better long-term fit and reducing the risk of distortion. Enhanced Dyeability: Mercerisation improves the ability of cotton fibres to absorb and retain dye. This results in brighter and more vibrant colours, making mercerised cotton a preferred choice for dyed textiles. The enhanced dyeability contributes to a more attractive and long-lasting appearance. Lustrous Sheen: One of the distinctive features of mercerised cotton is its lustrous or shiny appearance. The treatment process alters the surface of the cotton fibres, creating a smooth and reflective quality. This sheen adds a luxurious and aesthetic appeal to textiles, making them visually appealing. Dimensional Stability: Mercerisation imparts dimensional stability to cotton fabrics, ensuring that they maintain their shape and structure over time. This is particularly important for garments and textiles that require consistent sizing and appearance. Reduced Lint: Mercerisation can contribute to lint reduction on the surface of cotton fabrics. This quality is desirable for textiles like bed linens and towels, where lint can be a nuisance. Mercerising cotton enhances its strength, shrink resistance, dyeability, lustre, absorbency, and dimensional stability and reduces lint. These improvements make mercerised cotton a preferred choice for a wide range of high-quality textiles in the fashion, home, and industrial sectors.Mercerised Cotton and Non-Mercerised Cotton: Which Should I Choose?Mercerised cotton is a type of cotton that has been treated with a caustic soda solution to improve its properties. This treatment gives the cotton a greater affinity for dyes, allowing it to absorb colours more evenly and vividly than unmercerised cotton. Mercerised cotton also has improved strength and a lustrous appearance, making it ideal for projects that require durability and a polished finish.Maurice Brassard 8/8 unmercerised cotton yarnsOn the other hand, unmercerised cotton has yet to undergo this treatment and retains a softer, more muted texture. While it may not have the same lustre and strength as mercerised cotton, unmercerised cotton is preferred for its natural feel and breathability.Let's dig deeper into the different characteristics, as well as the pros and cons, of mercerised cotton and non-mercerised cotton.Pros and Cons of Mercerised CottonMercerisation involves treating cotton fibres with a caustic soda solution followed by neutralisation with an acid. This process causes the fibres to swell, resulting in several notable changes. Mercerised cotton offers several advantages, making it a popular choice in the textile industry. However, like any material, it also has its drawbacks.Advantages of Mercerised Cotton1. Lustre:Mercerised cotton boasts a higher sheen or lustre compared to its non-mercerised counterpart. The enhanced shine gives fabrics a luxurious appearance, making them ideal for high-end clothing and textiles.2. Strength:The mercerisation process significantly increases the strength of cotton fibres. This enhanced durability makes mercerised cotton well-suited for products requiring longevity and resilience.3. Colour Absorption:Mercerised cotton exhibits superior colour absorption capabilities. The fibres absorb and retain dyes more efficiently, producing vibrant and long-lasting colours. This makes it a preferred choice for fabrics where colour vibrancy is crucial.4. Smoothness:Mercerised cotton fibres become smoother due to the treatment, contributing to a softer feel in the fabric. The increased smoothness enhances the overall tactile experience.Disadvantages of Mercerised Cotton1. Cost:The mercerisation process adds to the production cost of cotton. As a result, mercerised cotton products may be more expensive than their non-mercerised counterparts.2. Environmental Impact:The mercerisation process involves the use of chemicals, including caustic soda. If it is not managed properly, the environmental impact of these chemicals can be a concern. Sustainable and eco-friendly practices are increasingly important in today's textile industry.3. Energy Consumption:Mercerisation requires energy-intensive treatments, contributing to higher energy consumption during production than non-mercerised cotton.4.
