An extrusion device that produces plastic film includes at least two feed units that feed feedstock for an extruder, wherein, in each feed unit an automatic cleaning device is arranged for a removal of feedstock from the feed unit when changing material in the extrusion device.

The invention relates to a solution for reducing and removing moisture from plastic pellets by means of absorption and condensation, in which energy consumption is reduced and the process is simplified, making use of infrared wavelength efficiency, and comprising the following steps: 1. a supply phase using a dosing tank; 2. a distribution phase using a pellet levelling and dispensing device, a conveyor belt and a vibrating motor on the conveyor belt; 3. a moisture-removal phase using one or more infrared wave emitters disposed in parallel, a ventilated or cooled motor for a set of emitters, an air-recirculation passage for a set of emitters, an input temperature probe, an output temperature probe, and a moisture control probe; and 4. a discharge phase in which the material from which the moisture has been removed is discharged using a thermally-insulated collector tank.

Disclosed is a method for preparing a fully-degradable non-woven fabric by spun-bonding, including: (S1) preparation of a poly(caprolactone-co-lactide acid) (P(CL-co-LA)); (S2) preparation of a copolymerized-modified poly(lactide acid) (PLA); and (S3) preparation of a full-degradable non-woven fabric using a spun-bond method. In this disclosure, the PLA is modified in gradient several times to prepare the full-degradable non-woven fabric in combination with an optimized spun-bonding method.

A fine fiber production method and a fine fiber production apparatus are provided. The fine fiber production method includes: discharging a flowable polymer compound from a discharge port provided at an extruder; forming fibers having a fiber diameter of from 50 nm to 15 μm by spraying, in a direction intersecting with a discharge direction of the flowable polymer compound, a pressurized gas from an air nozzle to the discharged flowable polymer compound, the air nozzle including a temperature control member and a spindle-shaped nozzle or a De Laval nozzle; and collecting the fibers using a collection member provided downstream in a gas spraying direction.

The present invention is to a composition made from a polyester produced by the acid or ester polyester process, a cobalt salt and a base, preferably an alkaline metal base. The composition can be made by blending a cobalt salt with a polyester which has been polymerized in the presence a alkaline metal ion derived from a basic alkaline metal compound, e.g. alkaline metal base or basic alkaline metal salt. The composition may optionally comprise an ionic compatibilizer, which may further be blended with a partially aromatic polyamide. This blend can be processed into a container having both active and passive oxygen barrier with an improved color and clarity than that achieved by cobalt alone. The use of the cobalt salt in combination with the base can also be used to improve the color of recycled polyester during processing.

This cellulose composition contains: (A) a water-soluble cellulose ether, (B) water-insoluble cellulose particles and (C) water. The cellulose composition serves as a novel biomass material which uses biodegradable cellulose that places little burden on the environment, and exhibits excellent shape retention properties.

A process for continuously preparing a polyolefin composition made from or containing a polyolefin and carbon black in an extruder device. The process includes the steps of supplying polyolefin in form of a polyolefin powder and carbon black to a mixing device; alternatively, (a) measuring the flow rate of the polyolefin powder supplied to the mixing device or (b) measuring the flow rate of the polyolefin pellets prepared in the extruder device; adjusting the flow rate of the carbon black to the mixing device in response to the measured flow rate of the polyolefin powder or adjusting the flow rate of the polyolefin powder to the mixing device in response to the measured flow rate of the polyolefin pellets; melting and homogenizing the mixture within the extruder device; and pelletizing the polyolefin composition into the polyolefin pellets.

Embodiments relate to a heat shrinkable film and a process for regenerating a polyester container using the same. The heat shrinkable film comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80° C. for 10 seconds and a melting point of 190° C. or higher as measured by differential scanning calorimetry. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.
