    摘要： A nonwoven wipe has multiplicity of fibers, bonded portions, and unbonded portions. The bonded portions are spaced apart from one another, each bonded portion comprises portions of the fibers that are bonded together, and each bonded portion has a thickness extending perpendicularly between opposite faces of the nonwoven wipe. Each unbonded portion comprises portions of the fibers that are not bonded together, and each unbonded portion has a thickness extending perpendicularly between the opposite faces of the nonwoven wipe. The thicknesses of the unbonded portions is greater than the thicknesses of the bonded portions. The bonded portions are sized and arranged for providing a desirable balance of properties.

    摘要： This invention discloses a new method to prepare the PLA/PP bi-component fiber filter media and the products fabricated by using of PLA/PP bi-component fibers according to this method. The method includes the following processes: 1. The preparation of PLA carding fiber flow. The PLA fibers are fed into an air carding machine, and then an orderly carded PLA fiber flow is formed after the carding. 2. The preparation of melt-blown PP fiber flow. The PP raw material is first melted under the temperature of 180-290 °C in a screw extruder, and then the extruded PP melt is filtrated and transported to the metering pump. After measuring, the PP melt is conveyed to the spinneret die to spin the fibers. PP fibers are drawn under the hot air with the temperature up to 250~300 °C, which is added from the both sides of the spinneret hole. Therefore the melt-blown PP fiber flow would be formed. 3. The preparation of PLA/PP bi-component fiber filter media. The PLA air-carded fiber flow is combined with melt-blown PP fiber flow at the mass ratio of PLA: PP = 40~60%:85~15%. After cooling, a fiber web is formed on the collector. The formed fiber web on the collector could be directly shaped into PLA/PP bi-component fiber filter media by thermo-bonding which is due to the presence of surplus heat in PP fibers. The mixing ratio of PLA and PP fiber mentioned above could be controlled by adjusting the amount of the PLA fiber fed into air carding machine and the metering pump in PP melt-blown fiber process. The filter media could be prepared by this method.

    摘要： In some embodiments, the inventive subject matter is directed to an arrangement of discrete elements of fill material on a substrate consisting of a sheet material wherein the discrete elements are fixed relative to the sheet material by pilings, fusion, and/or entanglement to fix the insulating elements in a layered arrangement over the sheet material. A second sheet of material may be used to create a sandwiched assembly of the discrete elements. In some embodiments, the inventive subject matter is generally directed to discrete elements of fill material that are engaged together to form a cohesive sheet-like or layered arrangement of the elements.
