Manufacturing and Consumption of Spunbond Fabrics
This fabric belongs to the category of non-woven textiles and is made of polypropylene. The fabric is also known as disposable fabric, non-woven, needle-punched non-woven, and spunbond non-woven. As mentioned, spunbond fabrics are among non woven fabrics, so no weaving process takes place on them. Therefore, special bonding processes are needed to partially connect the layers and make them relatively stable. Finally, depending on the final use and customer requirements, the necessary completion is done on the fiber web and the product is packaged.
Non-woven textiles are uniquely designed fabrics with different qualities that provide effective solutions for increasingly diverse applications in today’s life. Products that we see every day and are often unaware of their usage or even their existence, utilize these fabrics. To put it differently, non-woven textiles are a product of the present era. produced with modern and innovative techniques.
The usage of spunbond fabric is so diverse that almost everyone has to use them. Its wide range of application commences from teabags and even includes military purposes. Many people use this fabric daily, but they have no information about it and are fully unaware of its name or usage.
Non-woven fabrics are introduced according to ISO 9002 standards in 1988 and EN 29092 standards as follows: Non-woven textiles are layers or fibrous networks that are arranged regularly or randomly and have been linked together by friction, connection, or adhesion, except for paper and products that are woven, tufted, or felted using filament threads, whether or not needle punching is added.
Spunbond Fabrics vs Warp and Weft Fabrics
What makes spunbond fabrics so distinctive is that they are not made of fiber types like regular warp and weft fabrics, but are made of pressed fibers. Spunbond fabric is produced in various thicknesses and weights. To better illustrate the usage of spunbond fabrics, we can refer to the type of carpet weave.
Non-woven textiles are porous layers or fibrous networks made entirely or mostly of fibers, and they are created using processes other than spinning, weaving, or knitting. The layer, however, may resemble woven or knitted fabrics, carpets, or even paper, with a unique structure and designThe thickness of the layers can range from 25 micrometers to several centimeters, and the weight can range from 212 g/m to 2200 g/m. Non-woven textiles can be stiff and brittle like compacted paper or soft and flexible like regular fabrics.
The tensile properties of non-woven textiles may be relatively stable or so durable that they cannot be broken, or damaged by hand. The combination of fibers in non-woven textiles can be natural or synthetic, with lengths starting from 3 millimeters and more. The tensile properties of the fiber layer depend on frictional forces and the performance of the polymer layer added as a bonding adhesive. Some or all of the fibers may be bonded together by heat or solvent. Although the structure of the fabrics made from animal hair such as wool is similar to that described, they are not considered non-woven textiles. Paper, in which fibers are connected to each other by hydrogen, is also not a non-woven textile. In fiber-layer structures, the basic unit is fibers/filaments arranged in a layered configuration and connected to each other so that the distance between bonds is more than 100-50 times the diameter of the fibers. The main structure of all non-woven textiles compared to regular fabrics is the same fiber layer. Therefore, the main element is a single fiber. The arrangement of fibers in the layer can be low or high.
Features of Spunbond Fabrics
The factors that distinguish different types of spunbond Fabrics from each other include weight, width, color, and length of each roll. Additionally, these fabrics may or may not have the following features: water-resistance, printed or plain, antibacterial, anti-UV, and soft.
Color and Printing on Spunbond Fabrics
Spunbond fabric is produced in various colors, and It can be used either plain or printed with a desired design. Printing on spunbond fabrics is done in two ways: silk screen printing and flexo printing. Flexo printing is faster, cheaper, and more economical than silk screen printing, but the color quality in silk screen printing is better. However, in low quantities, silk screen printing is more affordable in terms of consumables.
