摘要： A fiber blending system includes an apparatus and method of forming a mat of cellulosic fibers and synthetic fibers, as well as a mat thereby formed. The method includes the steps of fiberizing cellulosic material into cellulosic fibers in a fiberizer, volumetrically metering a metered amount of synthetic fibers, and injecting the metered amount of synthetic fibers into the cellulosic fibers. The cellulosic fibers are blended with the metered amount of synthetic fibers in a blending chamber to form a fiber blend. The fiber blend is dispersed through a fiber disperser having apertures of a preselected size and shape to provide a dispersed fiber blend. A third type of fiber may also be mixed with the dispersed fiber blend. The dispersed fiber blend is collected as a mat on a fiber collector to provide a mat of blended cellulosic and synthetic fibers. The mat may be thermobonded by a thermobonder and sandwiched between a facing sheet and a backing sheet. By varying the aperture preselection, as well as the size and type of fibers, a bonded mat having desired mat characteristics is formed.

摘要： An absorbent article is described which may be formed at least in part of thermoplastic and other fibers. The article is densified along a first region and has a tear line defined in the first region. A second region of lower density than the first region is provided at the termination point of the tear line to assist in stopping tearing along the tear line. In addition, densified reinforcing regions can be provided outside areas where the tear line curves or switches directions. Perforations or cuts in the tear line may extend continuously around the corner of the tear line to assist tearing around the corner.

摘要： Articles are formed of materials which have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. The material is cut within the densified region or slightly outside the densified region to provide a soft peripheral edge. Absorbent materials may be thermobonded within the layer and surrounded by a densified edge to fix them within the article. The composite materials are used in manufacturing infant car seat liners and other articles. In addition, sections of the material may be densified and provided with weakened areas, such as perforations, to enable users to selectively separate the articles along the perforations.

摘要： Materials have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material-containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. Fire retardant materials may be thermobonded within the layer to fix them within the article. The densified edge also helps to fix these materials in place. The composite materials are used in manufacturing infant car seat liners and other articles. Fire retardant films may be included as cover sheets for these materials. These films are typically bonded at every point of contact to an underlying core.

摘要： A durable launderable towel has a thermobonded core of thermoplastic and other fibers. The towel has at least one cover sheet which is preferably formed with apertures and has a limited stretchability. Limited stretchability may be achieved by prestretching and heat setting the cover sheet prior to assembly into a towel. The towel is also densified in a field pattern and is typically densified at the peripheral edge. Embossing is preferably used to form these densified areas. The combination of thermobonding the core, embossing and the use of apertured cover sheets results in a towel having the softness, drape and feel approaching that of cloth. By controlling the embossing on the wiping surface of the towel, a towel with surfaces having different wipe dry characteristics and textures can be produced.

摘要： A disposable infant seat liner in accordance with the present invention includes an upper section, a middle section and a lower section. Plural shoulder strap receiving slotways are provided in the upper section. These slotways may be accessible from side edges of the infant seat liner. In one embodiment, three shoulder strap receiving positions are provided at each side of the upper section to accommodate shoulder straps of various infant seat designs. First and second leg or crotch strap receiving slotways are also provided in a lower section of the infant seat liner. In one specific embodiment, a Y-shaped leg strap receiving slotway is positioned below an upwardly facing U-shaped slotway. In another embodiment, the lower slotway is T-shaped. Arched side cuts may also be provided in the central section of the infant seat liner to accommodate waist straps and to facilitate fitting of the infant seat liner to an infant car seat. The slotways, cuts and slits may be selectively openable with perforations being provided for this purpose. In this latter case, a user need only open those perforations required to fit the infant seat liner to the user's particular infant seat.
