Textile coating and lamination are production methods of the textile products and stand out with technical performance and functional properties rather than the apperance and aesthetic advantages they provide. Being used in many areas including agricultural textiles, medical textiles, home textiles and protective clothes, coating or laminated fabrics have performance and functional properties which vary depending on the coating agent used, technique applied as well as the structure and features of the textile surface.
Polyurethane which is one of the most common coating products used in this field stands out with its high elongation value, resistance against weather conditions, rupture and abrasion and its tendency to repel oil and turn place under sunlight. Used in clothes, shoes and hand bags, low-grammage nylon jackets, waterproof and breathable clothes, life jackets, sports bags, tent and leather vanishing, polyurethane was discovered by Otto Bayer and his colleagues in 1937. Composed of polymers consisting of chains of organic units containing carbamate bonds, polyurethane was discovered by one of the biggest chemistry companies of the world and put into service of the textile sector.
INSQIN
In this system named INSQIN, a complicated co-polymer where the amount of polyurethane elastomer is not less than 5 % in the fiber structure is created and a molecular bow-like helical form is acquired. In this way, elastane natural rubber acquires an elongation capacity up to 700 % since its resistance is higher than rubber, which provides functional ease. Besides, thanks to INSQIN system, if elastomer fibers are used within the woven fabric structure, the possibility of hairiness is eliminated. It can also be used in narrow fabrics with the methods of yarn-warp or weft-knitting.
In this respect, Nicholas Smith, the Head of Textile Coating Department of Bayer MaterialScience, said that they made a revolution in the textile coating and lamination technologies with INSQIN technology they developed. Smith added that this technology which came out as a result of their long lasting R&D and P&D works will enter into use in many areas of application of textile in a relatively short period of time.
