Definitions

  • Methods of compression embossing fibrous webs are known in the art.
  • Methods of heat embossing fibrous webs including fibrous webs comprising thermoplastic fibers are also known.
  • the heat embossing is done by means of heated rollers, with the fibrous web travelling through the nip between the counterrotating heated rollers.
  • the rollers are usually heated a few degrees higher than the melting point of the thermoplastic fibers in the web or the temperature desired in the embossing process. This is necessary so that the web travelling quickly through the nip achieves the desired temperature.
  • Fabrics which have been heat embossed and in particular fabrics which have been heat embossed in a pattern by patterned rollers often display damage from excessive heat.
  • the fibers immediately adjacent the patterned regions are heated to a temperature sufficient to cause shrinkage and damage.
  • the heat radiated to the fibers next adjacent the patterned area also shrinks the web, blurring the line of demarkation of the pattern.
  • a combination of heat and pressure is used to compact the fibers in the patterned regions in the web. This combination of factors does not effectively radiate to the fibers next adjacent the patterned region of the fabric, creating a fabric with very sharp pattern delineation and high loft adjacent the patterned region.
  • GB-A-1 245 088 discloses a process in which a patterned fabric is produced by passing a web containing a thermoplastic through the nip of a set of rollers. One of the rollers is patterned and is heated to a temperature below the softening temperature of the thermoplastic. The pressure exerted at the nip together with the temperature of the patterned roller is sufficient to cause the thermoplastic to fuse and bond the densified regions together.
  • the present invention comprises a method as defined in claim 6 of pattern embossing a non-woven web of fibers comprising conjugate fibers and the fabric formed thereby.
  • the method comprises heat embossing the web at a temperature slightly below the softening point of the low melting point component of the conjugate fiber, and with the combination of pressure and temperature sufficient to cause cold flow of at least the low melting point component of the conjugate fibers to deform and compact the conjugate fibers, compacting the fibers of the web in only the patterned regions.
  • the fabric formed according to the method has a very sharp pattern delineation and high loft immediately adjacent the pattern.
  • the web contains at least 15 percent conjugate fibers.
  • the conjugate fibers are a sheath/core of high density polyethylene/polyester fibers.
  • the present invention also provided a non-woven fabric as defined in claim 1.
  • the present invention comprises a method of embossing a web comprising at least 15 percent conjugate fibers and the fabric formed thereby.
  • the conjugate fibers comprise a low melting point component and a high melting point component, and preferably comprise a sheath/core polyethylene/polyester fiber.
  • the conjugate fibers employ high density polyethylene, that is, linear polyethylene that has a density of at least 0.94, and a Melt Index ("M.L”) by ASTM D-1238(E) (190°C, 2160 g) of greater than 1, preferably greater than 10, and more preferably from 20 to 50.
  • M.L Melt Index
  • the fibers will be composed of 40 to 60 weight percent, and preferably 45 to 55 weight percent, polyester, the remainder being polyethylene.
  • the fabrics of the invention are produced by first forming a fibrous web comprising a loose array of the conjugate fibers, as by carding or air laying.
  • the exact weight of the fibrous web has not been found to be narrowly critical, although useful weights have been found within the range from 6.78 to 142.40 g/m 2 (0.2 to 4.2 ounces per square yard). This web is then conveyed to the nip of the embossing rollers.
  • a combination of heat and pressure is applied at the embossing nip combined to cause the low melting point component of the conjugate fibers of the web to cold flow.
  • the method of the present invention encompasses using patterned embossed rolls generally known in the art.
  • the pattern embossed rollers have raised patterned surface areas which contact and compress the web as it passes through the nip of a pair of counterrotating pattern emboss rollers.
  • the rollers are heated to a temperature many degrees above the effective temperature needed at the nip. This is necessary to maintain a good through-put speed of the web.
  • the elevated temperature assures that during the short amount of time that the web spends in the nip, the effective temperature within the web is reached.
  • the rollers are heated to a temperature below the softening point of the low melting point component of the conjugate fiber of the web which is to be processed through the nip of the rollers.
  • the combination of heat and pressure applied by the patterned embossed rollers causes at least the low melting point component of the conjugate fibers of the web to cold flow and deform and compact the conjugate fibers, compacting the fibers in the web, in only the patterned regions.
  • the fibrous webs used in practicing the method according to the present invention comprise at least 15 percent conjugate fibers and preferably sheath/core high density polyethylene/polyester conjugate fibers.
  • conjugate fibers which may be used in the method of the present invention are copolyester/polyester and nylon 6/nylon 66 fibers.
  • the web may be heated with heated air as a temperature sufficient to fuse the conjugate fibers to each other and to other fibers in the web to strengthen the fabric in the remaining, unpatterned regions.
  • Figure 1 illustrates a microscopic cross-section of a fabric formed according to the present invention.
  • the fabric shown generally at 10 has embossed densified regions 12 created by the deforming and compacting of the conjugate fiber, compacting all the fibers in the web in only the pattern embossed region.
  • the deformation and compaction of the conjugate fibers are accomplished by a combination of heat and pressure.
  • the heated embossed rollers are heated to a temperature slightly below the softening point of the low melting point component of the conjugate fibers. Sufficient pressure is applied in the patterned area to permanently deform the low melting point component of the conjugate fiber and hence the conjugate fiber.
  • any other fibers in the patterned regions of the web are compacted and the web is maintained in a densified state by the deformation of the conjugate fibers.
  • the patterned regions display an opacity that is believed due to the air fiber interfaces.
  • the deformation of the conjugate fibers is caused by cold flow of at least the sheath and perhaps the core of the fibers.
  • the fabric shows a very high loft and individual fibers 16 are seen. The high loft delineates the pattern of the fabric and indicates a lack of fiber damage in the regions immediatley adjacent the patterned regions.
