Nonwoven material
What is nonwoven fabric?
Nonwoven material is an alternative to traditional fabric, made from natural and synthetic or only synthetic fibers. Non-woven material has a wide range of usage from industrial purposes and medicine (isolating, interlining material, disposable clothing, underwear), to ordinary everyday use (tablecloths, cleaning wipes).
According to the composition and producing method, several types of nonwoven materials are distinguished:
Spunlace is a non-woven material consisting of natural and artificial fibers (viscose and polyester), which is produced by a hydrojet method. Spunlace technology originated in the 60-s of the last century, but was first officially introduced in 1973 by the company DuPont (Sontara).
The interlacing of the material fibers occurs under the influence of high-speed water jets under high pressure. Tightly fastened with water jets on a perforated drum. Usually the canvas breaks through alternately from two sides. The canvas can pass through the water jets a certain number of times (depending on the required strength of the fabric). At the last stage, the bonded canvas is dried in a special chamber using high temperatures, which ensures additional hygiene and purity of the obtained material.
In our products we use white spunlace with a density of 40 - 55 g/m2. Our materials contain from 40 to 70% viscose. If the material is 100% viscose (a natural raw material), then it becomes biodegradable.
According to its properties, spunlace is soft and pleasant to the touch, absorbs and retains moisture well, and does not lose its strength when wet.
We also use laminated spunlace for individual products, which differs from the usual one with an additional layer of polyethylene film that prevents the penetration of liquid fluids and bacteria.
Spunbond is non-woven material, as well as the name of the technology for the production of non-woven material based on fibers containing 100% polypropylene (synthetic fiber). Due to the synthetic origin, the material acquires a water-repellent property.
The polymer melt is released in the form of thin continuous fibers, which are drawn in the air stream and form a textile canvas on a moving conveyor. Next, the fibers are fastened with spot thermofixation.
In our products we use spunbond with a density of 15 -40 g/m2 in the following colors: white, blue, green, pink, yellow.
We also use laminated spunbond for individual products, which differs from the usual one with an additional layer of polyethylene film that prevents the penetration of liquid and bacteria.
SMS is a three-layer non-woven material, consisting of 100% polypropylene fibers. A distinctive feature is the presence of meltblown material between the two layers of spunbond. The material has become widely known for its use in the production of protective surgical masks.
Meltblown is a kind of polypropylene wool, which has increased hydrophilic and barrier functions to the penetration of microorganisms, it absorbs and distributes liquid well over the entire material area . The inner, hydrophilic layer quickly absorbs and passes liquid (e.g. sweat) through itself, and the outer hydrophobic layer prevents the penetration of liquid from the outside. This creates good tactile properties of the material with a feeling of "dryness".
In the meltblown production process, long fibers are spun from molten polymers that are blown from nozzles onto a ribbon. The flow spreads the molten polymer material and solidifies into a fibrous canvas. The Meltblown method produces very thin and light fibers that darken the cotton. They improve the filtration, acoustic properties or absorbency of the final product.
Schematically, the manufacturing process of the material is as follows:
In our products we use SMS with a density of 20 - 40 g/m2 in blue and white colors. The material is waterproof.
