A method of manufacturing a plurality of colors of bulked continuous carpet filament from a single multi-screw extruder which, in various embodiments, comprises: (A) passing PET through an extruder that melts the PET and purifies the resulting PET polymer melt; (B) adding a liquid colorant to the polymer melt using a liquid metering system; (C) using one or more static mixers (e.g., up to forty static mixers) to substantially uniformly mix (e.g., homogeneously mix) the polymer melt and the liquid colorant; and (D) feed the uniformly mixed and colored polymer melt into a spinning machines that turns the polymer into filament for use in manufacturing carpet, rugs, and other products.

The present invention concerns a method for processing and detoxification of a material, especially a thermoplastic material, and for removal of contaminants or impurities from this material, wherein the material is heated under vacuum in at least one receiving tank, mixed and possibly comminuted, and wherein a rinsing medium is introduced into the receiving tank beneath the material level, conducted through at least a partial region of the material, and the rinsing medium enriched or saturated with contaminants is brought out from the receiving tank once more. According to the invention, the quantity of rinsing medium introduced into the receiving tank is less than 0.1 liter per hour per kilogram of material or material throughput per hour, while at the same time the vacuum in the receiving tank is kept constantly below 100 mbar.

Systems (200) and methods for making different plastic products (202, 204) in a single melting process are provided. A method includes melting a plastic resin in a first extruder (104) to form a melt (106) and transferring at least a portion of the melt to a second extruder (114). Any portion of the melt (106) that is not transferred to the second extruder (114) is formed into a first plastic product (202). Additives (116) are blended with the melt in the second extruder to form a second melt (118), and a second plastic product (204) is formed from the second melt (118).

The present invention relates to a method for producing an antimicrobial polyester fiber yarn containing volcanic ash, the method comprising the steps of: crushing and heating volcanic ash, and allowing the heated volcanic ash to collide under an air stream in an air classifier mill system to obtain volcanic ash powder; subjecting the volcanic ash powder to nano-milling to obtain nano-sized volcanic ash particles; disintegrating the volcanic ash particles to prepare nano volcanic ash; mixing the prepared nano volcanic ash with polyester for fiber use at a weight ratio of 10:90-30:70, followed by melt extrusion, thereby preparing a highly dispersed volcanic ash master batch; and mixing the volcanic ash master batch with polyester for fiber use at a weight ratio of 4:96-8:92, followed by spinning to produce an antimicrobial polyester fiber yarn.

Disclosed are plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste made with a system comprising thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.

A method for manufacturing an elastic layer on site provides for downsizing an aged artificial turf into artificial turf fragments, processing the artificial turf fragments for generating a plastic melt, after the plastic melt solidifies, downsizing the solidified plastic melt into plastic particles, mixing the plastic particles with a binding agent for forming a fluid elastic composite, and applying the fluid elastic composite on a substrate at the site for forming the elastic layer.

The invention relates to an apparatus for the pretreatment and subsequent conveying or plastification of plastics, with a container with a mixing and/or comminution implement that is rotatable around an axis of rotation, wherein, in a side wall, an aperture is formed, through which the plastics material can be removed, a multiscrew conveyor being provided, with at least two screws rotating in a housing, wherein the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, where, on the outflow side, there is an offset distance between the longitudinal axis of the screw closest to the container, on the outflow side, and the radius that is parallel to the longitudinal axis, and in that the screws co-rotate.

System and method for producing plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste comprises the thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.

The invention relates to a method and a device for introducing and/or adding non-dry-powder additive materials and/or coating materials with a liquid, solid, semi-solid, or paste-like consistency or in suspended or emulsified form, for example, peroxides, fats, waxes, IV improvers, polymers, or similar materials, to an existing lumpy or particulate material which is moved and mixed, and optionally warmed and reduced to small pieces in a receptacle and/or compressor (1), said material being in particular polymer particles and/or flakes, wood fibers, paper cuttings, or similar materials. According to the invention, the additive material is introduced below the level of the material and/or material particles already in the receptacle (1).

This invention relates to a mobile water sports court comprising a Net Module (3), a Line Module (2), and a Support Module (1). The Net Module (3) is positioned above the water surface and includes a Net Body (31), Upper and Lower Holder Cables (32, 33), and Sliding Hooks (34). The Line Module (2) is placed on the water surface and features Border Lines (20) with Marker-Holding Ropes (21) supporting cylindrical Boundary Markers (22), secured with Carabiners (23) and Corner Clips (24). The Support Module (1) includes Anchor Screws (11), Ground Screws (12), Guy Ropes (13a), Anchor Ropes (13b), Lower and Upper Support Pillars (14, 18), a Centerline (15) and Anchor Buoys (16), which connect the modules and secure the court. Additionally, a Pool Fixation Kit (10) with Threaded Anchor Plates (10a), Eye Bolts (10b), and Cushion Feet (10c, 10d) is provided for easy anchoring in pool environments, replacing traditional anchor methods. This modular structure offers stability, adaptability, and portability for water sports courts in both open water and pool settings.
