A constantly growing variety of different materials is used in the textile industry to manufacture laminated and coated textiles for a wide range of products. Whether clothing textiles of all kinds, textiles for car parts, products for the building industry or home products – the bonded substrates in laminated textiles are as diverse as the purpose of the products: foams, fleece, cotton or polyester, and glassfibre fabric with aluminium foil. The possibilities to add special functions to textiles are just as diverse.
Membranes and textiles are laminated using thermoplastic and reactive hot melt adhesives. Moisture-curing PUR hot melt adhesives meet highest requirements for a broad spectrum of adhesion to different materials, high compound strength even with small application amounts, low processing temperature, as well as the resistance necessary in processes such as washing or sterilisation. Thermoplastic hot melts are adapted to the individual and often very specific demands. In membrane laminating, they support special properties in the end product, such as breathability, flame retardancy or noise absorption. A wide range of adhesion is here also an essential requirement due to the different substrates from which membranes are manufactured, such as PP, PE or PU.
Selected Jowat adhesives for the textile industry are tested and certified according to the ECO PASSPORT of the Hohenstein Institute. This certification verifies the human ecological safety of the adhesive for the use in textiles according to OEKO-Tex® Standard 100. The OEKO-Tex® Standard guarantees to the consumer that a textile product does not contain any harmful substances above a binding limit. The OEKO-TEX® tests for harmful substances take into account the purpose of the textile and divide articles into four product categories. From articles for babies and children up to 3 years, to furnishing materials such as covers for upholstery furniture – the closer the skin contact and the more sensitive the target group is, the stricter are the human ecological requirements which have to be met. Jowat adhesives fulfil the criteria of product class 1.
Medical textiles are important helpers in healthcare and fulfil a variety of essential functions. For instance, pressure-relieving mattress toppers help prevent bedsores, and surgical gowns are a hygienic and breathable work clothing. Other daily used items are surgical drapes manufactured from nonwovens which are laminated with special foils. Adhesives used in membrane laminating have to promote the liquid absorbing function of the material compound. Another major factor in this regard is the application method. Thermoplastic and reactive hot melts for instance are applied in a diamond pattern which allows the material to absorb liquids into the spaces between the adhesive.
Reactive PUR hot melts are particularly suitable for laminating membranes in the manufacture of incontinence underpads. Underpads generally consist of a compound of cotton textile with membranes. In this application, PUR hot melts impress with high washing resistance at high temperatures as well as sterilisability.
