    Abstract: A method of making gardening fabric includes melting a polymer and processing the melted polymer, drawing the processed polymer into filaments, forming a web from the filaments, and autogenously bonding the web to form the gardening fabric as a nonwoven fabric sheet. The autogenous bonding includes forming a pattern into the nonwoven fabric sheet, the pattern being formed by areas of the nonwoven fabric sheet that exhibit a higher degree of fusion than other areas. The pattern may include a lattice forming a plurality of identically sized geometric areas of the bonded fibers, and the lattice is formed by areas of the bonded fibers that exhibit a higher degree of fusion than the identically sized geometric areas. The pattern may include a lattice forming a plurality of identically sized s-shaped areas of the bonded fibers, or a lattice forming a plurality of randomly shaped and sized non-geometric shapes.

    Abstract: A system and process for making a polymeric fibrous material having increased beta content is provided herein. The system is configured for meltblowing polymer into a fibrous material having high beta crystalline content and has an extruder for melting and moving a polymer to a meltblowing die. The meltblowing die has a longitudinally extending die tip with a plurality of spinnerets substantially equidistantly spaced from each other and a longitudinal fluid material flow through passage disposed along each longitudinal side of the die tip configured to axially attenuate the melted polymer from the die tip in fibrous form. A plurality of liquid spray nozzles are configured and disposed to spray a liquid into the fibrous melted polymer attenuated from the die tip.

    Abstract: A hybrid non-woven web is disclosed which is a matrix of a stream of fibers of a first material joined to streams of first and second spun-blown fibers. Each of the first and second spun-blown fibers are formed from a thermoplastic composition that contains at least one polymer having a melt flow rate of from between about 5 grams/10 minutes to about 6,000 grams/10 minutes at 230° C. Each of the first and second spun-blown fibers also have an average diameter of between about 1 microns to 10 microns and a standard deviation of from between about 0.9 microns to about 5 microns. In addition, the hybrid non-woven web has a tensile strength of at least about 5 gf/gsm/cm width, measured in a machine direction. An apparatus and a method of forming the hybrid non-woven web are also disclosed.
