 ===Fire and flame===
 The use of flame treatment is regulated by the provisions of building codes or other provisions for fire safety, such as for clothes for work where they can be exposed to fire and heat. Even for upholstery and curtains there is a need to provide flame treatment. In principle, all fibers of organic origin can be ignited at high temperatures, but the most important is to prevent local fires from spreading. Frequently used textile fibers, such as cotton, can have fire retardant properties by various treatments. The most common way to provide fire protection on standard textile fibers is by impregnation with chemicals which contain nitrogen and phosphorus or a combination of halogenated hydrocarbons and antimony. Phosphorus-nitrogen compounds can be wash-resistant to cellulose fibers and is also available in flame-washable polyester fibers. Halogenated hydrocarbons and antimony usually provides poor wash ability and are therefore used mainly in materials that are not going to be washed. Another relatively frequent treatment for fire protection of wool fiber and its protein is to use salts from metals such as titanium and zirconium. There are also synthetic high temperature fibers to choose as an alternative to chemical treatment.<br/>

 DWR (durable water repellent) is a coating added to fabrics at the factory. Durable water repellents (DWRs) are applied to garments and products to allow for breathability and water repellency. Common factory-applied treatments are fluorochemicals. Certain DWRs are known to have persistent, bioaccumulative and toxicological effects on the environment. The durable water repellent coatings used in the fashion and textile industry are currently not bio-based or biodegradable. Water repellent coatings also inhibit recyclability.
 =====Innovation opportunities=====
-• Investigate non-fluorochemical coatings, such as silicones, polyurethane (PU) and waxes. Although these coatings are recyclable on their own, they inhibit recyclability when applied to a dissimilar base layer. These coatings have the potential for recyclability if applied to a similar base layer.'''1'''<br/>

 ====Stain repellents====
-Stain repellent finishes are used to provide stain, soil and grease release and repellency to fabrics. Fluorochemicals are the most employed repellents used for textiles. The largest concern for chemicals used for soil and stain repellent finishes is perfluorooctanoic acid (PFOA), which is used in the manufacture of stain repellent finishes for textiles. PFOA is also produced indirectly through the gradual breakdown of fluorochemicals.'''3''' PFOA is very persistent in the environment and has been found at very low levels both in the environment and in the blood of the general U.S. population.'''4''' Recycling of textiles with stain repellent finishes is also very difficult. Flurochemicals are currently being phased out by major industrial users.'''5'''

The organotins compound tributyltin (TBT) persists in the environment and builds up in the body. TBT is listed as a “priority hazardous substance” under European Union regulations and requires measures to be taken to eliminate its use.'''6''' Organotins are highly toxic to aquatic species, are persistent, moderately bioaccumulative. A recent report conducted by Greenpeace revealed organotins detected in several activewear products.'''6'''

 Another important issue is the appearance of purity - especially on white fabrics where every little smudge is visible and remaining traces of dirt are visible even after washing. To make the fabric resistant to dirt, the same type of treatment is used as for water and oil-repellent treatment. These treatments means that dirt often get stuck in the form of aqueous or oily film on the fibers and cannot wet the fibers so it will instead “purl off”. This is where the expression stain repellent has its origin. There are also treatments that will facilitate the cleaning of laundry. This makes the fiber materials more easily can release dirt. Treatment is done with substances that make the fiber surfaces hydrophilic and easier to wet (soil loosening). Examples of such substances are carboxymethylcellulose (CMC), polyacrylic acid or ethoxylates.

 ===Mold protection===
 Need for mold protection is greatest on natural fibers since they are easier to be attacked by mildew and rot than synthetic fibers. It is not allowed to perform mold protection on textile products in Sweden. Even though, goods with this type of impregnation still reaches the country through imports.

 ==Vacuum suction==
 Another technique that has been tested is ''vacuum suction''. The excess liquid is sucked through a column from the fabric after dipping. Uneven woven edges can cause problems and with the edge not properly sealed the vacuum varied and dewatering was uneven. Increasing in usage of the technique has been substantial since the problems with edge seal has been solved by using a flexible tube. The equipment works best on normal fabrics that are not too sparse and that can improve dewatering significantly.
