Problems solved by technology

In the production of wigs such as SOFT DREAD, in addition to requiring a large curvature, it is especially important to make the original silk present a dense small curvature, which is more similar to the bending effect of African real hair, but the existing processing methods are difficult. achieve

Embodiment 1

[0015] (1) Preliminary finalization

[0016] Wrap the PTT precursor evenly on the calibrating frame, then put it into the calibrating cabinet, set the working temperature of the calibrating cabinet to 117°C, and the calibrating time to 30 minutes;

[0017] (2) Stereotype consolidation

[0018] After the step (1) ends, the working temperature of the setting cabinet is 135°C, and the setting time is 30 minutes;

[0019] After 30 minutes, open the door of the shaping cabinet, take out the processed PTT precursor, and let it cool down naturally.

[0020] It is measured that the shrinkage rate of PTT raw silk reaches 50%, and the hand feels hard, which is beneficial to the subsequent process of winding the tube.

Embodiment 2

[0022] (1) Preliminary finalization

[0023] Wrap the PTT precursor evenly on the calibrating frame, then put it into the calibrating cabinet, set the working temperature of the calibrating cabinet to 110°C, and the calibrating time to 40 minutes;

[0024] (2) Stereotype consolidation

[0025] After the step (1) ends, the working temperature of the setting cabinet is 130°C, and the setting time is 40 minutes;

[0026] After 40 minutes, open the door of the sizing cabinet, take out the processed PTT precursor, and let it cool down naturally.

[0027] It is measured that the shrinkage rate of PTT precursor reaches 51%.

Embodiment 3

[0029] (1) Preliminary finalization

[0030] Wrap the PTT precursor evenly on the shaping rack, then put it into the shaping cabinet, set the working temperature of the shaping cabinet to 120°C, and set the shaping time to 25 minutes;

[0031] (2) Stereotype consolidation

[0032] After the step (1) ends, the working temperature of the setting cabinet is 140°C, and the setting time is 25 minutes;

[0033] After 25 minutes, open the door of the sizing cabinet, take out the processed PTT precursor, and let it cool down naturally.

[0034] It is measured that the shrinkage rate of PTT precursor reaches 50%.

[0035] The PTT raw silk processed by the shaping cabinet has a relatively regular and fine curvature, and the raw silk shrinks slightly at high temperature; because of the irregular curvature, it has a certain matting effect; at the same time, it feels hard and is wound in the next process. It can better maintain the state, not easy to mess up, and improve production effi...

Abstract

The invention discloses a microbending treatment method for polytrimethylene terephthalate (PTT) protofilament for artificial hair. The method comprises the following steps of: 1) performing primary sizing, namely winding PTT protofilament on a sizing frame uniformly, placing in a sizing cabinet, and setting the working temperature of the sizing cabinet to be 110 to 120 DEG C and sizing time to be 25 to 40 minutes; and 2) sizing and solidifying, namely after the step 1), setting the working temperature of the sizing cabinet to be 130 to 140 DEG C and the sizing time to be 25 to 40 minutes, finally opening a door of the sizing cabinet, taking the treated PTT protofilament, and naturally cooling.

Description

technical field [0001] The invention belongs to the field of artificial hair manufacture, and in particular relates to a micro-curvature treatment method for PTT precursors for artificial hair. Background technique [0002] SOFT DREAD is a wig style that is popular in the United States and Africa. Artificial hair uses PTT precursor as the main raw material for making SOFT DREAD. In the production of wigs such as SOFT DREAD, in addition to requiring a large curvature, it is especially important to make the original silk present a dense small curvature, which is more similar to the bending effect of African real hair, but the existing processing methods are difficult. achieve. Contents of the invention [0003] The purpose of the present invention is to provide a micro-curvature treatment method for PTT precursors for artificial hair. By strengthening the micro-curvature of the precursors, the elasticity of the mainspring is enhanced, so that the time for the mainspring to...
