  • Patent number: 11946169
    Abstract: A process for making a spunmelt nonwoven web including the steps of providing a mixture of recycled polypropylene, extruding the recycled polypropylene mixture to form a molten recycled polypropylene mixture, filtering the molten recycled polypropylene mixture through a filter to form recycled polypropylene filtrate, dosing the recycled polypropylene filtrate into the spunmelt production line by an amount of 80% to 100% by weight, passing the recycled polypropylene filtrate through at least one spinneret of the spunmelt production line to form filaments at a spinning speed of greater than 1200 meters per minute, cooling and drawing the filaments, and depositing the filaments on a moving belt to form at least one layer of the spunmelt nonwoven web made up of 80% by 100% by weight of recycled polypropylene fibers.

  • Publication number: 20220364281
    Abstract: A method of forming a hydro-patterned nonwoven web including the steps of forming a nonwoven batt comprising continuous spunmelt fibers, calender bonding the nonwoven batt to form a thermobonded precursor nonwoven web with a bond pattern that defines bond impressions and unbonded areas between the individual bond impressions, and hydraulically treating the thermobonded precursor nonwoven by a plurality of steps of water injection as the thermobonded nonwoven web passes over a screen. The bond pattern has specific features that provide advantages in terms of mechanical properties and visual appearance of the final nonwoven product.

  • Publication number: 20210316238
    Abstract: A nonwoven fabric including a first layer made of spunbond fibers and a second layer made of meltblown fibers, wherein the first layer is bonded with the second layer, and wherein the spunbond fibers of the first layer are interspersed with the meltblown fibers of the second layer so that the nonwoven fabric exhibits enhanced breathability and filtration properties. In exemplary embodiments, the nonwoven fabric may be used in personal protective equipment, such as, for example, face masks and respirators.

  • Patent number: 10639212
    Abstract: An absorbent article having improved softness signals is disclosed. The article may include a topsheet or a backsheet including a nonwoven web. The web may have a basis weight of 30 gsm or less, may be formed of spunlaid fibers including polyolefin and up to 5 percent by weight TiO2, and may be impressed with a pattern of bond impressions to a bond area percentage of at least 10 percent forming a pattern of bonded regions and raised regions. The web may have opacity of 42 or greater; have an average height difference between bonded regions and raised regions of at least 280 ?m; be hydroengorged; and/or have a cross-machine direction tensile strength of 350 gf/cm. A nonwoven web manufactured to have a suitable combination of such features exhibits an enhanced appearance of softness, soft tactile feel and satisfactory mechanical attributes, while being relatively cost effective.
