Non-woven fabric, is made of random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, and price. Low cost, recyclable, and so on. For example, polypropylene (pp material) pellets are used as raw materials, which are produced by high-temperature melting, spinning, paving, and hot-rolling and continuous one-step process. It is called cloth because it has the appearance and some properties of the cloth.
Thermal bonding is the process of using heat to bond or stabilize a web structure that consists of a thermoplastic fiber. All part of the fibers act as thermal binders, thus eliminating the use of latex or resin binders. Thermal bonding is the leading method used by the cover stock industry for baby diapers. Polypropylene has been the most suitable fiber with a low melting point of approximately 165C. It is also soft to touch. The fiber web is passed between heated calendar rollers, where the web is bonded. In most cases point bonding by the use of embossed rolls is the most desired method, adding softness and flexibility to the fabric. Use of smooth rolls bonds the entire surface of the fabric increasing the strength, but reduces drape and softness.
Therefore, in the non-woven fabric, S, SS,SSS, SMS mean the following:
S: spunbonded non-woven fabric = hot-rolled single-layer web;
SS: spunbonded nonwoven fabric + spunbonded nonwoven fabric = hot rolled from two layers of web;
SSS: spunbonded nonwoven fabric + spunbonded nonwoven fabric + spunbonded nonwoven fabric= hot rolled from three layers of web;
SMS: spunbond non-woven fabric + meltblown nonwoven fabric + spunbond non-woven fabric = three-layer fiber mesh hot rolled;
XianTao QS Nonwoven Co., Ltd maks S, SS, and SMS nonwoven fabric. S and SS nonwoven fabrics are mainly used for furniture, agriculture, hygenic products, and packaging products. And SMS nonwoven fabric is mainly for medical products, like surgical gowns. We are now exporting these non-woven fabrics to different countries in the world.
