One of the types of non-woven fabrics is spunbond fabrics. Like Meltblown fabrics, spunbond (spun) fabrics are a type of fabric that is used in a wide variety of applications in the textile industry and is completely obtained from polypropylene raw material. The difference from other fabrics is that it is nonwoven, non-woven, non-woven or felt-like.
Spunbond (spun) fabrics are fully recyclable and resistant up to 90 degrees. There are hydrophobic (waterproof) and hydrophilic (water-retaining) types. In addition, by adding additives that provide ultraviolet resistance during production, the resistance of the fabric against sunlight is increased. On the other hand, spunbond fabrics have antibacterial properties and are produced in various colors.
Spunbond fabrics show a multi-layer structure and are generally close to 3 microns in diameter. Meanwhile, the diameter of human hair is between 50-70 microns. Spunbond fabrics, with its multi-layer structure, show allergen and dust-holding properties up to 99,8 percent. In addition, its texture is synthetic and is not affected by water and moisture.
Among the physical properties of textile products in general, tensile strength is a remarkable feature. The main factor affecting the fabric shrinkage is the moisture absorption power of the fiber. In addition, if the structure of the fabric is tight, the yarn begins to swell with the expansion of the fiber. Then the warp height of the yarn in the fabric increases and the length of the yarn is shortened by buckling. This situation naturally causes the fabric to shrink and shrink.
Under normal conditions, synthetic fibers have the lowest shrinkage ratio. As such, it is rare for nonwoven fabrics to shrink and shrink in general.
Materials used in the textile industry must be resistant to external factors exposed during use. The situation is no different for spunbond fabrics. These fabrics are also passed through quality control tests before being offered to consumers. One of these tests is the tensile strength test. Considered in these testsSeveral standards are:
Our organization provides tensile testing services within the scope of spunbond fabric testing services to demanding healthcare organizations and manufacturing companies 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.
