    摘要： Nonwoven web and method of making including interbonded thermoplastic fibers in an array of hollow projections extending outwardly from at least one surface of said web. The projections are separated by land areas of interbonded fibers, and the fiber orientation is greater in the projections than in the land areas. Either the projections or the land areas may be perforated as desired for controlled porosity and fluid flow properties. The nonwoven webs of the invention may be made by a number of processes but, preferably, are made by forming directly on a surface with corresponding projections with or without apertures and a vacuum assist or by forming on an apertured surface with a pressure differential sufficient to draw the fibers through the apertures forming the projections. The disclosure includes such webs with added fiber layers and as components of a wide variety of products including personal care items such as liners for sanitary napkins, household products such as cleaning materials and wipers, in the service product area such as towels, washcloths and bathmats, in the marine and automotive area as scrubbing and protective applicators, and in the hospital and veterinary areas as wipes and dispensing cloths. The method and apparatus disclosed may be varied as to steps and configuration to impart desired web constructions and properties, and preferred embodiments are disclosed.

    摘要： Nonwoven wiper having improved absorbency characteristics and streak free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers and, on either side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter. These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others. The continuous filament layers provide strength and low lint properties while the combination exhibits improved wiping characteristics. The laminate is preferably bonded by application of heat and pressure and the individual components are preferably treated with a surfactant. The preferred combination of a layer of meltblown polypropylene microfibers having on either side a spunbonded polypropylene filament layer is particularly effective as an all purpose wiper.

    摘要： Improved low linting, low sodium ion content, wettable nonwoven wiper is provided through the use of a treatment involving a mixture of wetting agents. The wiper of the invention maintains the excellent wiping and low linting characteristics of nonwoven wipers while greatly reducing the amount of sodium ions present in the wiper and avoiding contamination problems especially prevalent in wipe applications for the electronics industry. Specifically, the combined wetting agent treatment includes a mixture of sodium dioctyl sulfosuccinate such as Aerosol OT and a nonionic surfactant such as alkyl phenoxy ethanol (Triton X-100). The preferred mixtures are about 25 to 75% sodium dioctyl sulfosuccinate with a ratio of about 40 to 60 preferred and about 50/50 especially preferred. The result is a wiper having essentially the desired wettability of those made with 100% sodium dioctyl sulfosuccinate wetting agent and yet having only about half the sodium ion content. The wiper, therefore, can be employed advantageously in clean room applications such as the manufacture of micro-electronic devices where the prsence of greater amounts of sodium ions can be very detrimental due to changes of electrical properties of the semiconductor devices. Substrates for the wiper may include various synthetic filamentary material such as polyolefins, including polyethylene and polypropylene, and others which will be apparent to those skilled in the art.
