Wool fibers possess a unique surface morphology characterized by overlapping cuticle scales.<\/p>\n<p>These microscopic scales create directional friction: fibers resist movement in one direction but interlock easily in the opposite direction. When exposed to heat, moisture, and mechanical agitation, these scales hook together, causing felting shrinkage.<\/p>\n<p>Internally, wool consists of:<\/p>\n<ul>\n<li>Cuticle (outer protective scale layer)<\/li>\n<li>Cortex (protein-rich structural core)<\/li>\n<li>Medulla (in some coarse fibers)<\/li>\n<\/ul>\n<p>Keratin protein, rich in cystine disulfide bonds, provides elasticity and resilience. However, this same structure contributes to felting behavior.<\/p>\n<p>Untreated <span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/www.giantcarbonisedwool.com\/fr\/categorie-de-produits\/tissu-de-laine\/\">wool fabrics<\/a><\/span> shrink because scale interlocking creates irreversible fiber entanglement. Superwash technology modifies this scale behavior.<\/p>\n<h2>What Does Superwash Wool Mean?<\/h2>\n<p>Superwash wool undergoes a finishing process that reduces or neutralizes scale friction. There are two primary industrial methods:<\/p>\n<ul>\n<li>Chlorination + Polymer Coating (Traditional Superwash)<\/li>\n<li>Plasma or Enzyme-Based Treatments (Modern Eco Alternatives)<\/li>\n<\/ul>\n<p>In the traditional process, chlorine treatment partially removes or smooths the scale edges. A polymer resin coating is then applied to encapsulate the fiber, preventing scale interlocking.<\/p>\n<p>In modern eco-friendly approaches, low-impact plasma treatments alter the fiber surface energy without heavy chemical discharge.<\/p>\n<p>Superwash wool, therefore, means wool that is:<\/p>\n<ul>\n<li>Lavable en machine<\/li>\n<li>Resistant to felting shrinkage<\/li>\n<li>Dimensionally stable<\/li>\n<li>Softer in hand feel<\/li>\n<\/ul>\n<div class=\"mceTemp\"><\/div>\n<h2>What Is Carbonised Wool Superwash?<\/h2>\n<p>Before wool is treated for superwash properties, it often undergoes carbonising, particularly when derived from raw fleece containing vegetable matter (burrs, seeds, straw).<\/p>\n<p>Carbonising is a purification process in which wool is treated with dilute sulfuric acid, dried, and heated. The acid carbonizes plant-based impurities, making them brittle and removable without damaging protein fibers.<\/p>\n<p>When <span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/www.giantcarbonisedwool.com\/fr\/produits\/laine-carbonisee\/\">laine carbonis\u00e9e<\/a><\/span> then undergoes superwash treatment, it becomes Carbonised Wool Superwash\u2014a premium-grade fiber that has:<\/p>\n<ul>\n<li>Removed vegetable contamination<\/li>\n<li>Enhanced surface uniformity<\/li>\n<li>Reduced felting tendency<\/li>\n<li>Improved dye absorption consistency<\/li>\n<\/ul>\n<p>This dual-process treatment is common in high-quality knitting yarns and performance wool textiles.<\/p>\n<figure id=\"attachment_709\" aria-describedby=\"caption-attachment-709\" style=\"width: 350px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-709\" title=\"Laine carbonis\u00e9e\" src=\"https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-300x200.jpg\" alt=\"Laine carbonis\u00e9e\" width=\"350\" height=\"233\" srcset=\"https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-300x200.jpg 300w, https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-1024x684.jpg 1024w, https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-768x513.jpg 768w, https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-1536x1025.jpg 1536w, https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1-18x12.jpg 18w, https:\/\/www.giantcarbonisedwool.com\/wp-content\/uploads\/2025\/11\/Carbonised-Wool-1.jpg 2000w\" sizes=\"(max-width: 350px) 100vw, 350px\" \/><figcaption id=\"caption-attachment-709\" class=\"wp-caption-text\">Laine carbonis\u00e9e<\/figcaption><\/figure>\n<h2>Comparison Between Untreated Wool, Superwash Wool, and Carbonised Wool Superwash<\/h2>\n<table style=\"width: 90.5458%;\">\n<tbody>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\"><strong><b>Caract\u00e9ristique<\/b><\/strong><\/td>\n<td style=\"width: 19.7657%; text-align: center;\"><strong><b>Untreated Wool<\/b><\/strong><\/td>\n<td style=\"width: 20.937%; text-align: center;\"><strong><b>Laine superwash<\/b><\/strong><\/td>\n<td style=\"width: 51.8302%; text-align: center;\"><strong><b>Laine carbonis\u00e9e Superwash<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Felting Resistance<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Faible<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Haut<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Very High<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Machine Washable<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Non<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Oui<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Oui<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Surface Smoothness<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Natural Scales<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Polymer-Coated<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Refined + Coated<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Dye Uniformity<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Mod\u00e9r\u00e9<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Haut<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Very High<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Vegetable Impurities<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Possible<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Possible<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Removed<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 22.1083%; text-align: center;\">Softness<\/td>\n<td style=\"width: 19.7657%; text-align: center;\">Variable<\/td>\n<td style=\"width: 20.937%; text-align: center;\">Softer<\/td>\n<td style=\"width: 51.8302%; text-align: center;\">Soft + Uniform<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Carbonised Wool Superwash provides superior consistency for industrial-scale textile production.<\/p>\n<h2>Is Superwash Wool Itchy?<\/h2>\n<p>The itchiness of wool depends primarily on fiber diameter (measured in microns), not merely treatment type.<\/p>\n<p>Fine merino wool (&lt;20 microns) is generally soft and non-itchy.<\/p>\n<p>Coarser wool (&gt;30 microns) can feel prickly.<\/p>\n<p>Superwash treatment can slightly smooth the fiber surface, reducing friction against skin.

In many cases, it is less itchy than untreated wool.<\/p>\n<h2>The Role of Fiber Diameter in Comfort<\/h2>\n<p>Fiber fineness is the primary determinant of prickle sensation. When fiber ends exceed approximately 30 microns, they are stiff enough to resist bending upon skin contact, triggering nerve receptors.<\/p>\n<p>Superwash treatment does not change fiber diameter.
