Conclusion

Spinning flax is particularly complex due to the variation in the scale of the flax fiber, which is not precisely defined as it can be either individual or in cohesive bundles. As a result, the fineness and length parameters of flax fibers are highly variable and difficult to control, which adversely affects the quality of the yarns produced.

The technology used worldwide until the first quarter of the 21st century for wet spinning flax was developed in the 1930s and has changed very little since then. The very nature of this process makes it difficult, if not impossible, to automate. The production costs of yarns obtained using this traditional wet method are very high. The technology used for processing tow, dry or semi-wet spinning, is derived from that used for wool and is not perfectly suited to flax. However, it is modern and partially automated. Its production...
