Generally, polymers with high molecular weight and broad molecular weight distribution such as polypropylene and polyamide are spunbonded to produce smooth webs. In the production of fibers by melt spinning, medium melt viscosity polymers are commonly used. The properties of polyethylene fibers that are melted and spun by traditional methods are lower than polypropylene fibers. With the advances in polyethylene technology, spunbond fabrics with properties not yet achieved with polypropylene will be produced more widely.
Spunbond products, geotextiles and disposable medical and hygiene products are used from production. Since fabric production is carried out together with fiber production, it is more economical to obtain nonwoven fabrics in this way. The Spunbon technique places the binding device in line with the spinning and combines fiber spinning with the web formation process. In some embodiments, the network is connected at a separate stage. However, multiple types of joining are applied to the same network and this arrangement is more flexible.
The spinning process is similar to the production of continuous filament yarns. It uses similar conditions for a particular polymer. As the melt comes out of the polymer nozzles, fibers are formed and are quenched by cold air. In this way, a wide network is produced.
Spunbonded webs (spunbond fabrics) fall between paper and woven fabric in terms of their properties and have a wide range of product properties from very light and flexible to heavy and rigid structures.
The pH value of textile products refers to the residual acid and alkali content in fabrics, which are indicators of harmful substances affecting human health. According to national and international standards, it should be controlled that the pH value of textiles directly exposed to the skin, and especially baby clothing, is between 4 and 8,5. For textile products that are not directly exposed to the skin, the pH value should be between 4 and 9. Basically, the pH of human skin is between 5,5 and 7 and is weakly acidic. The high pH value of textiles destroys the weak acid environment on the surface of human skin and causes symptoms that will cause itching and leave the skin vulnerable to other pathogenic bacteria. In addition, high or low pH value of the fabric causes damage to the fabric during storage. In short, the pH value of textile products is not only related to the health of the consumer, but also closely related to the quality of textile products. In this respect, it is important to keep the pH value under control in spunbond fabrics. It is.
Our organization provides pH testing services within the scope of spunbond fabric testing services to demanding healthcare organizations and manufacturers, within the framework of national and international standards, with a trained and expert staff and advanced technological equipment, among numerous testing, measurement, analysis and evaluation studies.
