Said geometric structures of circularly shaped forms are intersecting with each other at the non-embossed intersection points (20) and unit shaped emboss structures have uniform dimensions.
  • Nonwoven fabrics are one of the oldest and simplest textile fabrics. Nonwoven fabrics can be produced by a variety of known processes other than weaving or knitting.
  • Nonwoven products produced by known techniques are used in various applications such as; disposable and medical applications, hygiene products, diapers, incontinence pads, feminine hygiene articles or nappies.
  • the nonwoven fabric properties depend on following particulars to a great extent,
  • the emboss patterns mainly effect the properties of the produced nonwoven fabric such as, softness, strength, elongation or pilling properties.
  • Various emboss patterns are applied on nonwoven webs to improve these kinds of properties.
  • Fabric properties of nonwovens range from crisp to that soft touch to harsh, impossible to tear to extremely weak.
  • EP2479331 discloses a method of using high crystalline polypropylene mixed with low crystalline polypropylene as raw material with reduced fiber denier to obtain enhanced softness of spun bond nonwoven fabrics. But using reduced denier can cause problems. For example; increased hydrophobicity of the web can be a result of reduced denier and this may cause problem with regard to used areas of nonwoven fabrics such as top sheet. This application does not express the effect of embossing structure on softness of nonwoven fabric which is a cost saving application to obtain soft surfaces.
  • US4333979 is related to light weight nonwoven webs, that have embossed patterns composed of fused bond areas covering a specific range of web surface with specified frequency of bond areas and web thickness.

  • Nonwoven fabrics typified by spun bond or melt blown nonwoven fabrics are usually partially thermo bonded via an embossing roll in order to prevent the falling-off of fibers which form the nonwoven fabric and by this way to improve the strength of the fabric.
  • spun bonded or melt blown webs are bonded by thermal bonding with application of hot calender.
  • Emboss roll is used as hot calender which has specific design pattern to obtain embossed patterns on nonwoven web. By the way, strong nonwoven fabric is obtained.
  • an improved embossing design is applied on nonwoven fabric (2).
  • Said embossing design pattern is concerning geometric structures of circularly shaped forms (4).
  • the nonwoven fabric (2) having emboss structures of being partially thermo bonded non-continuous lines gives excellent softness to a nonwoven fabric comparing to having an emboss pattern formed nonwoven by a continuous emboss line.
  • Emboss pattern that is formed by non-continuous emboss lines as dotted emboss lines (8) are round shaped and superior in softness to a nonwoven fabric having an emboss pattern formed as angled such as triangle, square, rhombic or rectangular.
  • polyethylene coating can be applied on polypropylene webs to obtain improved softness but it causes pilling and lack of strength. So high weight fibers are used to achieve targeted strength.
  • Nonwoven fabrics which use polypropylene as fiber former prevents pilling of fibers comparing to polyethylene coated fibers.
  • thermo bonded polypropylene fiber having specified bonding areas gives an excellent strength to nonwoven fabric that is equivalent or higher as conventional nonwoven fabrics. Besides the weight of the fiber used is reduced as an important economical factor.
  • the present invention relates to a nonwoven fabric (2) comprising an embossed portion (14) and a non-embossed portion (16).
  • the present invention provides improvements in continuous fibers bonded thermoplastic webs, concerning specific embossed patterns.
  • nonwoven fabric states that in the present invention, fibers are held together by a process of bonding to form a nonwoven fabric.

Depending on the embossed bonding area, and emboss structure, physical and mechanical properties of the nonwoven fabrics are changed.
  • spun bond process is widely used to produce nonwoven fabrics.
  • Typical spun bond process components are a polymer feed, an extruder, a quenching system, a drawing and deposition system, a web formation, a bonding and a winding system.
  • spun bonded production requires the steps;
  • a melt solution of a fiber forming polymer or a mixture of polymers is extruded through a system providing spinnerets under a high velocity current of air. Said formed fibers are deposited on to a conveyor belt to form a web. The belt than carries the web to a bonding stage where consolidation of web occurs to form nonwoven fabric.

  • the nonwoven fabrics of the present invention have strong webs, low elongation and filament diameter in the range of 1-3 deniers and more specifically 1,5-2 denier. Small denier is preferred because, homogen distribution of filaments are required to form web structures which is preferred to be used as top sheet or other water and air pervious layers of hygiene articles.
  • melt blown process is one of the widely used processes to produce nonwoven fabrics in which the production steps are quite similar to spun bonded webs.
  • extruded polymers pass through the holes in a spinneret into a high velocity current of air.
  • melt blown method from spunbond method is an increased force of air current used which breaks the filaments rather than just drawing them to produce fibers of varying lengths.
  • Melt blown fibers have smaller diameters.
  • the fiber size is influenced by, process air volume, throughput, temperature, number of holes of spinneret and type of polymer resin. By applying higher process air temperature then melting temperature of the used polymer endless filaments can be obtained by melt blown process.
  • Melt blown fabrics have, filament diameter in the range of 1-3 denier, more specifically 1-1,5 denier. Melt blown filament denier is smaller than others which allow producing hydrophobic such as liquid and air impervious web structure. Nonwoven fabrics produced by this technique are preferably used as back sheet or as cuffs of diapers or hygiene articles.
  • Thermal bonding in which the fibers bond together when heated under pressure, may require a bonding agent.
  • melt blown method comprises the steps;
  • Bicomponent multilayer fibers can be used to produce a bonded fabric with one of the components being thermoplastic to facilitate heat bonding and the other component having the property that will enhance the quality of final fabric area density in the process is controlled by the speed of conveyor belt.
  • the created product is relatively stiff and dense which is not desired to be used in hygiene articles. There is a need to have softer products which are strong enough.
