摘要:
A method of forming a chopped strand mat formed of bonding materials and wet use chopped strand glass fibers (WUCS) which demonstrate a reduced occurrence of static electricity is provided. In one exemplary embodiment, the occurrence of static electricity on the glass fibers is reduced or eliminated by increasing the total solids content on the glass fibers, such as by applying an increased or excess amount of size composition to the glass fibers. Alternatively, an anti-static agent may be added directly to the sizing composition and applied to the glass filaments by any suitable application device. The antistatic agent may be applied to the wet chopped strand glass prior to chopping the strands or as the wet chopped strands are packaged. The static free wet use chopped strand glass fibers may be used in dry-laid processes to form chopped strand mats having a reduced tendency to accumulate static electricity.

The flexible, reusable packaging container of the present invention is comprised of a packaging material. The packaging material is comprised of one or more layers of coating disposed on one or more layers of textile substrate. The coating layer may be comprised of a stiffening agent for providing support to the packaging container. The stiffening agent may provide a gas and/or liquid impermeable barrier between the contents of the container and the textile substrate. The stiffening agent may also include chemicals which impart antifungal or antibacterial properties to container. The textile substrate typically provides an aesthetically pleasing feel and appearance to the outside of the packaging container, as well as providing functional attributes such as water repellence, stain resistance, and/or anti-static resistance. The resulting packaging container possesses increased strength, puncture resistance, and resistance to de-lamination over the current paper or plastic packaging containers.

A non-woven mat useful for a wide variety of purposes, including forming reinforced resin products, is produced in a manner having different specific uses of, and advantages over, conventional chopped strand mats and conventional glass tissue. The mat is preferably made by the foam process (but may be made by the liquid process), and at speeds well in excess of 60 m./min., and has a substantially uniform construction even when low density (e.g. 100 g/m or less). At least 20 % (preferably at least 85 %) of the fibers are in fiber bundles with between 5-450 fibers/bundle. The fibers (typically at least 85 %) have a length between 5-100 mm, preferably 7-50 mm, substantially the same as the length of the fiber bundle they are in. The fibers are preferably held in the bundles by substantially non-water soluble sizing, such as epoxy resin or PVOH. The fibers in the bundles typically have diameters of approximately 7-500 microns, preferably about 7-35 microns. The bundles may comprise at least 10 % reinforcing fibers, such as glass, aramid or acrylic.

The present invention provides a needled mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The needled mat includes a primary layer of a plurality of unidirectional continuous glass fiber strands coated with a composition which is compatible with the thermosetting matrix material and a secondary layer positioned thereon of a plurality of randomly oriented, generally continuous and/or chopped glass fiber strands coated with a composition which is compatible with the thermosetting matrix material. The mat has a total surface weight ranging from about 1300 to about 11,500 grams per square meter.

This invention provides a three-dimensional (3D) multifunctional knitted fabric structure comprising two independent layers (1 and 3) connected by cross-threads (2) being able to be applied as absorbency structure in medium incontinence men´s reusable underwear. The structure is produced in a single step using weft-knitting technology and designed to perform several functions in a single fabric. The inner layer (1), to be in contact with human body, is responsible to transport liquid, urine and perspiration from the human body to the outer layer (3), through the cross-threads (2), keeping dry the human skin. Cross-threads (2) are responsible to keep apart both independent layers and to transport liquid from the inner layer (1) to the outer layer (2). The outer layer (3) is responsible to absorb the liquid and, at same time, to control the odor and microorganisms proliferation generated by the urine. The outer layer (3) is coated or laminated (4) with a moisture control polyurethane in order to prevent liquid passage to the user paints and at same time to provide vapor transmission.
