A recycled cellulose raw material and a method for recycling a cellulose raw material from blended textile waste with high reliability and yielding high raw material quality is shown, the method comprising the steps in the given order: providing the blended textile waste containing at least one cellulose component and at least one synthetic polymer component, treating the blended textile waste in a non-oxidizing aqueous treatment medium in order to degrade the at least one synthetic polymer component, whereby the treatment is carried out at a temperature between 100° C. and 200° C., and obtaining the recycled cellulose raw material from the treated blended textile waste.

A method for applying a thermoreactive seam tape to a seam is provided. The thermoreactive seam tape may be positioned adjacent to the seam, which may include a first fabric surface and an adjacent second fabric surface. The thermoreactive seam tape may include an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam. The thermoreactive seam tape may further include an exterior surface opposite the interior surface, where the exterior surface is substantially non-planar with respect to the interior planar surface along a length of the thermoreactive seam tape. Heat and pressure may be applied to the thermoreactive seam tape, wherein the heat and the pressure facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

The invention relates to a process for extracting polyester from packaging. In particular, the invention relates to packaging comprising one or more dyes such as black packaging. The claim process uses a two stage extraction process to convert waste polyester in clean, reusable polyester.

The invention relates to a process for extracting polyester from fabric. In particular, fabric comprising polyester and one or more dyes. The claimed process uses a multistage mechanism to separate dyes from polyester containing garments and reconstitute the polyester.

Synergistic visbreaking composition of peroxide and a hydroxylamine ester for increasing the visbreaking efficiency for polypropylene polymers at melt extrusion temperatures below 250° C. and its use in visbreaking polypropylene. The present invention is furthermore related to the use of such visbroken polypropylene polymers for producing melt blown non-wovens with improved barrier properties.

A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric.

A moveable seam welding machine, system, and method of use is provided. The seam welding machine includes at least one sensor that generates at least one data point having geolocation coordinates incorporated or integrally formed therewith. The data point typically relates to the integrity or quality of the welded seam created by the machine. The sensor generates data points which may be evaluated in alarm logic for abnormalities or anomalies. The geolocation coordinates inherent or integral to the data point may be plotted or registered overtop satellite imagery. The coordinates of the anomalies or the registered image, or both, can be provided to the workman or operator so he/she may manually inspect the geolocation at where the abnormal or anomaly data point was generated by the sensor to spot check the welded seam by hand.

A system for preparing a polylactic acid (PLA) spunbond nonwoven fabric is provided. In particular, the system includes a first PLA source configured to provide a stream of molten or semi-molten PLA resin; a spin beam in fluid communication with the first PLA source, the spin beam configured to extrude and draw a plurality of PLA continuous filaments; a collection surface disposed below an outlet of the spin beam onto which the PLA continuous filaments are deposited to form the PLA spunbond nonwoven fabric; a first ionization source positioned and arranged to expose the PLA continuous filaments to ions; and a calender positioned downstream of the first ionization source.

A method for producing a low viscosity polypropylene composition may include melting a polypropylene-based composition; reducing a viscosity of the polypropylene-based composition; and optionally, repeating the melting and the reducing steps to form a low melt viscosity polypropylene-based composition; wherein the melting and viscosity decreasing steps are performed in the presence of at least one free radical generator and at least one pro-degradant stearate.

A system for making a nonwoven nonwoven spun-bond or melt-blown fabric has a spinneret for spinning fibers or filaments, a cooler downstream of the spinneret for cooling the spun fibers or filaments, a stretcher downstream of the cooler for stretching the cooled fibers or filaments, and a conveyor downstream of the stretcher. The stretched and cooled fibers or filaments are deposited as a nonwoven web on the conveyor. Sensors measure input parameters at the spinneret, at the cooler, at the stretcher, and/or at at least one diffuser or at the conveyor. An evaluating unit for determining an output parameter from the measured input parameter with respect to a predetermined reference parameter.

A mat seal for an electrical connector includes a plurality of through-holes extending in a through-hole direction through the mat seal, a grid of a first material having a plurality of grid meshes, the grid is arranged with the through-holes extending through the grid meshes, a first material layer of a second material disposed on a first side of the grid, and a second material layer of a third material disposed on a second side of the grid opposite the first side. The first material of the grid has a greater compression modulus than the second material of the first material layer and the third material of the second material layer.
