Rippling
This is where the seeds are taken off the plant. Rippling involved combing the seeds off with a coarse comb.
Retting The flax fibres are held together in the stems by woody material and cellular tissue, and retting is where the deseeded crop of flax straw is subjected to a controlled chemical or biological treatment to make the fibre bundles more easy to separate from the woody part of the stem.
Flax can be water-retted, dew-retted or chemically-retted. Water-retting is where the flax plants after pulling are tied up in sheaves and put in special dams or ponds for one to two weeks. This method can cause pollution. Today this method is seldom used in Europe, and water retting is more normally carried out in controlled conditions in tanks.
With dew-retting the flax straw is spread on the ground after pulling and left in the fields for 2 to 8 weeks, depending on the weather. This is the most common method in Western Europe, and is less expensive than water-retting in tanks.
Scutching & Hackling
This is a mechanical operation which, by breaking and beating the flax straw, separates the textile fibres in the stem of the plant from the woody matter which is then used for the manufacture of chipboard. No part of the flax plant is wasted. Fibres are then hackled (combed) to separate long line and short tow fibres. Line fibres then go through a process where they are drafted and doubled, until a rove (a slightly twisted sliver of flax fibre) has been formed. They then undergo the wet spinning process. Line fibres produce fine, strong yarn. Short tow fibres are dry spun and a heavy, coarse yarn results, ideal for use as furnishing fabrics, heavier apparel and knitwear.
