Definitions
- pectose The usual retting in pits transforms, by an action of biological microbian nature the coat of parenchyma, called pectose, which is uniting the fibres to the wood of textile materials.
- the intermediate lamella existing between the fibrous cells in the fibre fascicles are composed of pectose and lignin, the latter offering a much greater chemical stability.
- the reaction producing pectic acid in a gelatinous form does also take place in the presence of a catalyzator.
- This colloidal substance gives to the fibres their resistance, their elasticity, their brilliant and onctuous glaze and their susceptibility of splitting.
- the flax loses all its qualities and can also be destroyed.
- the new invention suppresses all these numerous drawbacks and first quality flax is obtained after a sole operation. workmanship is considerably reduced, the production resulting from the scutching is increased; the fibres of the plant are entirely transformed in flax and the tow formation is avoided. The process eludes radically all the disgusting smells, allows a rapid drying and destroys the centers of putrefaction.
- the new process can be performed in the actual retting pits without any change in the existing installations or in the working manner.
- the above mentioned special compound to be added to the retting water is a compound dissolvable in water. It is composed of saponified fatty stuffs to which are added in certain proportions, varying with the fibre and its destination, salts from strong bases and weak acid. These salts thus formed, undergo within the retting water, acting a catalyzator, a more or less complete decomposition in free acid and free base, a hydrolytic reaction giving rise to a compound altogether hydrogenizing and oxidating.
- the saponified fatty substances completely divided and dissolved in the retting water, they allow the fibres to be impregnated by the necessary greasy and pectic elements.
- This coating protects the fibres from the action of the free nascent alkali liberated in this incompletely saturated medium, the latter acting exclusively on the pectose.
- the fatty stufis are principally provided by linseed-oil, and, the special compound intervenes at the rate of l to 2% of the weight of flax in working.
- a retting process according to claim 2 wherein the amount of soluble agent employed does not exceed 2% by Weight of the fibres being treated. i: .5., A retting process-according to :claim 2, wherein the components of the soluble agent are added separately to the retting water.
