Polymorph Transition
Chemical restructuring of the internal lattice of flax fibers converts the native crystalline structure into a highly disordered amorphous state to improve dye uptake and flexibility. In Mercerization stages, cellulose ii decrystallization occurs when concentrated alkali treatments disrupt the hydrogen bonding networks of the flax fibrils. The resulting molecular rearrangement is documented in the mill’s internal laboratory report to verify that the fiber has reached the required chemical reactivity.
Structure Modification
Sodium hydroxide concentrations must be managed to prevent complete dissolution of the cellulose while achieving the desired amorphous transition. An over-treated fiber suffers from loss of mechanical strength, which causes yarn breakage during high-speed drafting and interlacing. The process parameters are recorded in the batch processing ledger, ensuring that the run remains within the safety tolerances of the spinning mill.
Quality Verification
X-ray diffraction measurements verify the efficiency of the molecular restructuring by comparing the treated batch against the buyer’s contract specifications. When the decrystallization index meets the target value, the yarn is cleared for high-performance linen warp preparation. This physical change ensures that the finished cloth exhibits a uniform dye density that satisfies the aesthetic requirements of the international export market, as recorded in the final quality dispatch note.
