Embodiment Construction

[0010] The technique of the present invention adopts two sizing steps, and the composition ratio of the used sizing solution changes to some extent for the characteristics of each sizing, and the steps of its embodiment are as follows:

[0011] 1. For the first sizing, immerse the pure ramie yarn in the slurry for 20 seconds, then take out the pure ramie yarn. The components of the slurry are 25kg of corn modified starch, 1.2kg of emulsified oil, 0.5kg of wax flakes, and 0.4kg of smoothing agent , propylene pulp 2.5kg, water 1.2T (ton), and the pure ramie yarn is 250kg;

[0012] Two, dry, put the pure ramie yarn of sizing for the first time into an oven, and dry the moisture in the pure ramie yarn;

[0013] 3. For the second sizing, the dried pure ramie yarn is immersed in the slurry for 20 seconds again, and then the pure ramie yarn is taken out. The composition of the slurry is 27kg of corn modified starch, 1.2kg of emulsified oil, 0.5kg of wax flakes, Smoothing agent 0.4kg...

Abstract

The invention relates to a pre-treatment technology in the weaving field, and concretely relates to a pure ramie yarn sizing technology. The technology is characterized in that two-time sizing is adopted, pure ramie yarns are immersed in a slurry for 20s, are taken out and are dried, and the obtained dried pure ramie yarns are immersed in the slurry for 20s again, are removed and are dried. The slurry for sizing comprises 25-27kg of modified corn starch, 1.2kg of emulsified oil, 0.5kg of a wax disc, 0.4kg of a smoothing agent, 0.5-3.5kg of a propylene slurry and 1.2T of water, and the weight of the pure ramie yarns is 250kg. The two-time sizing technology allows feather of the ramie yarns to be fully covered, eliminates a mutual feather entanglement phenomenon, is convenient for weaving; the mutual feather entanglement phenomenon is eliminated, so the batch warping operation can be omitted, and the easy head tearing phenomenon caused by the elasticity decrease of the yarns due to warping is avoided, thereby the weaving efficiency is substantially improved.

Description

technical field [0001] The invention relates to a pretreatment process in the field of weaving, in particular to a sizing process for pure ramie yarn. Background technique [0002] Due to the long hairiness of pure ramie yarn, it is difficult to cover the hairiness by manual sizing, and the uncovered hairiness is entangled with each other during weaving, resulting in unclear warp openings and difficult to weave. Therefore, large pulp vats are generally selected to warp in batches, but the yarn counts warped in batches are inelastic during weaving, and it is easy to form fried ends when the ends are broken (that is, a broken end will cause the next few or even More than a dozen yarn breaks), it is also difficult to weave. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a pure ramie yarn sizing process to solve the technical problem that hairiness is difficult to cover. [0004] Processing step of the present i...
