Latest Patents

One of Trimble's latest patents is focused on composite nonwoven fabrics. This invention provides composite nonwoven fabric laminates and processes for producing such materials. The fabric consists of a web of thermoplastic filaments laminated to at least one other web. The filaments are preferably spunbonded continuous polyolefin filaments, which have an oxidatively degraded outer sheath portion to enhance interfilamentary bonding and improve fabric laminate strength. In a preferred embodiment, two outer nonwoven webs made of oxidatively degraded spunbonded filaments are positioned around and laminated to a web of meltblown microfibers, forming a spunbond/meltblown/spunbond fabric. These fabrics can be utilized in various applications, including medical garments and disposable adsorbent products.

Another significant patent by Trimble is an apparatus and method for producing a web of thermoplastic filaments. This invention features a slot draw attenuator apparatus designed to produce webs of spunbonded thermoplastic filaments with improved cover, even at low basis weights. The filaments are introduced to a slot draw attenuator equipped with corona electrodes, which create an electrostatic charge that induces repelling forces in the filaments. This innovation allows for better spreading of the filaments before they are randomly deposited onto a forming belt.
