Fiber Oil Extractor

Rapid Grease Extraction Apparatus, Testing Standards of Rapid Grease Extraction Apparatus:Edana method ERT 155

Applications:

Rapid Grease Extraction Apparatus is designed to determine the grease or finish content of wool or synthetic samples by solvent percolation and evaporation. Suitable for fiber, yarn or fabric. Available with 1, 2 or 3 extraction units.

Product Information:

The Rapid Grease Extraction Apparatus was developed specifically for obtaining the oil content of tops and similar materials sufficiently quickly for the results to be available at the time of processing.

The principle of extraction is percolation of a solvent through the wool sample in a simple metal tube. The extract, as it drips from the tube, is collected by a light aluminium tray held between two metal rings mounted on a temperature-controlled hot-plate.

Features:

1.The instrument consists of pedestal, extraction tub, weight, plunger, cotton wool plug, tray, and the hot-plate.

2.The tube should be positioned in the hole in the lower support member of the apparatus, and the plunger boss placed in the hole in the upper support member.

3.In use the plunger is placed through the boss and down into the tube. The weight is then located on top of the plunger.

Testing Method:

Before starting a series of tests, the hot-plate is allowed to warm up to a suitable temperature (set by the power regulator knob). The correct temperature has been obtained when the solvent evaporates from the dish almost as quickly as fresh solution filters through to replace it. This prevents flooding of the tray and losing oil to the brass ring.

The temperature must not be too high, however, or the solvent will evaporate violently as the drops of solution hit the hot tray.

Before each test a pre-weighed aluminium tray is placed on the hot-plate brass ring. The tray location ring is then placed on the tray to secure it and to maintain a good thermal contact with the lower ring. The bottom of the tray must not touch the hot-plate.

This test method is most suitable for extracting loose wool or combed slivers, but it may also be used for yarn. It is not suitable for fabric unless it is first disintegrated into yarn to facilitate uniform packing in the extraction tube.

FAQ

(1) What is the Fiber Oil Extractor?

It is a laboratory instrument used to determine the grease or finish content in wool, synthetic fibers, yarns, and fabrics.

(2) What is this equipment used for?

It is used for fiber quality control, monitoring finishing oil content, and evaluating fiber treatment processes in production and research labs.

(3) What types are available?

Single, double, or triple extraction unit configurations for different throughput requirements.

(4) What industry problems can it solve?

Ensures accurate measurement of grease or finish content, supports QC in wool and synthetic fiber production, and assists in R&D of fiber finishing processes.

(5) How is it operated?

Load fiber or yarn into the extraction tube, apply weighted plunger, run solvent percolation on the temperature-controlled hot-plate, then evaporate solvent and read grease content.

(6)Why is fiber oil content testing important for textile manufacturers?

Fiber oil content directly affects fiber processing performance, including spinning behavior, friction characteristics, and downstream textile production. An incorrect amount of finishing oil may cause problems such as unstable processing, inconsistent fiber performance, or changes in fabric quality. Testing fiber oil content helps manufacturers control finishing processes, verify raw material quality, and ensure different production batches meet internal requirements.

(7)Which standards are related to fiber oil content testing?

Fiber oil content testing methods vary depending on fiber type and industry requirements. Commonly referenced methods include ASTM D2257 – Standard Test Method for Extractable Matter in Textiles and GB/T 6504 – Test method for oil content of chemical fibers. Users should select the appropriate standard based on the material being tested and the requirements of their quality control system.

(8)What is the difference between fiber oil content testing and extractable matter testing?

Fiber oil content testing focuses on measuring the amount of oil or finishing agent present on fibers, which is especially important for chemical fiber production. Extractable matter testing is a broader concept that measures substances removed from textile materials by a solvent, which may include oils, finishes, and other soluble components. The exact interpretation depends on the material and test method being used.

(9)How do manufacturers choose a suitable Fiber Oil Extractor?

When selecting a Fiber Oil Extractor, manufacturers should consider the fiber types they test, required testing standards, sample processing capacity, extraction method, and laboratory workflow. The equipment should match the actual testing requirements rather than simply focusing on basic specifications. Textile manufacturers and laboratories usually prioritize stable operation, repeatable results, and compatibility with their existing testing procedures.
