This invention relates to antimicrobial materials and articles, such as fibres, yarns, and their incorporation into textiles, packaging for food or beverages, or articles of clothing such as gloves. The antimicrobial fibres and yarns may be formed of a polymer and may comprise silver particles dispersed therein. The present invention contemplates a polymer batch precursor to the fibre of the invention and further products formed of the fibre or the polymer batch, for example textiles.

The invention discloses environment-controlling fibers, method manufacturing the same and fabrics using the same, which adopts polyolefin material, optoelectronic material, thermoelectric material, piezoelectric material and catalyst material, to make fibers and fabric by melting, mixing, drawing and weaving. The fabrics are used in all kinds of environmental control products or for organic agriculture. To use green energy such as solar light energy, solar thermal energy, wind energy, hydro energy, geothermal energy and other renewable energy to stimulate the function of the special material within the fibers, so that the fabrics can remove pollutants in the environment and produce self-purification function to achieve the purpose of improving the environmental conditions or promote plant growth.

A process for preparing fibers made from or containing propylene homopolymer having: a melting point ranging from 150° C. to 164° C.; a fraction soluble in xylene at 25° C. between 6.0 wt % and 2.0 wt %; a fraction soluble in acetone 25° C. between 0.5 wt % and 2.0 wt %; a ratio fraction soluble in xylene at 25° C./fraction soluble in acetone 25° C. between 0.30 and 0.60; a polydispersity index ranging from 2.8 to 4.5; and a melt flow rate (ISO 1133, 230° C./2.16 kg) between 2 to 40 g/10 min.

The present invention relates to a process for the production of a nonwoven fabric. In particular, the present invention relates to the production of a nonwoven fabric having desirable tactile and haptic properties, as well as to the nonwoven fabric itself. The process requires the selection of specific materials and process conditions. The fabric is produced from a masterbatch of isotactic polypropylene homopolymer and a surface-treated calcium carbonate filler.

A method of making nonwoven webs comprising providing a spinneret wherein the spinneret includes a pattern of conduits, the pattern of conduits forming an extrusion region; directing only a first stream of molten propylene polymer having a first temperature into a region adjacent of the first side of the spinneret, directing only a second stream of molten propylene polymer having a second temperature into a region distal to the first side of the spinneret, extruding only the first stream of molten propylene polymer through the exit openings in a first zone; extruding only the second stream of molten propylene polymer through the exit openings of a second zone; the second zone is distal to the first side with the first zone being between the second zone and the first side.

The present invention provides a modified cross-section hollow fiber, wherein the fiber comprises a hollow part, a shape maintaining part and a volume control part, the volume control part can have a shape protruding in the direction opposite to the center of the fiber, and an end part has a round shape.
