て変色するタイプである。The thermochromic material is a thermochromic material containing a conventionally known thermochromic dye, for example, an electron-donating color-forming organic compound, a color developer of the compound, and a color reaction of the two. A thermochromic material containing three components of a compound serving as a medium to be generated or a thermochromic material exhibiting a color change in the form of fine particles of a resin solid solution of the above component (for example, JP-B-51-3541)

The color changes before and after a predetermined temperature (color change point), and only one specific state can exist in a normal temperature range between the two states before and after the change. That is, the other state is maintained while the heat or cold required for the state to develop is applied, but returns to the state exhibited in the normal temperature range if the application of the heat or cold disappears, so-called, This type changes color by showing a small hysteresis width (ΔH) for temperature-color density due to temperature change.

The system described in JP-A-264285, which is colored with a thermochromic material containing a color-memorizing thermochromic dye that exhibits a large hysteresis characteristic and changes color, is effective. The dye changes color with a large hysteresis width (ΔH). That is, the shape of the curve plotting the change in the coloring density due to the temperature change is different from the case where the temperature is increased from a temperature lower than the color change temperature range to the case where the temperature is decreased from the temperature higher than the color change temperature range. It is a type that changes color following a very different path.

It is encapsulated in a capsule (particle size: 1 to 30 μm, more preferably 5 to 20 μm), applied, and melt-molded by kneading the microcapsule pigment in a thermoplastic.

用される。When the amount of the water repellent attached to the filament surface is 0.10% by weight or less as a solid content with respect to the filament, the water repellent effect is poor. On the other hand, when the amount exceeds 10% by weight, spinning, twisting, flocking, etc. In post-processing, there is a tendency for troubles to occur due to the occurrence of a lack of excess adhesion and adhesion (adhesion) between filaments. An adhesion ratio of 0.5 to 6.0% by weight, more preferably 1.0 to 2.0% by weight is effective. In addition, the spinning oil agent for fibers applied to the present invention is attached to facilitate hair styling with a comb, and a silicone-based lubricant, liquid paraffin, fatty acid esters and the like are applied.

る。[Function] An appropriate amount of the water repellent is attached to the surface of each filament, the water repellent effect is effectively exhibited, and the hair is immersed in the bath and after the discoloration operation, drains quickly and dries quickly.
Also, by using an oil agent in combination, proper lubricity is imparted when hair is combed, thereby satisfying hair styling properties. A treatment liquid in which a water repellent and a fiber spinning oil are mixed is attached to the surface of the filament discharged from the spinning nozzle, and then a filament having a desired thickness is formed by a drawing step. The curing treatment of the agent is also performed at the same time.

状態に戻る。In the hair of the present invention, in a system formed of a coloring material containing a thermosensitive pigment exhibiting a thermochromic property having a small hysteresis width (ΔH), the color changes before and after the color changing point as a boundary, and both before and after the change. Among the states, one specific state is present in the normal temperature range, and the other state returns to the state exhibited in the normal temperature range when the application of heat or cold required to develop the state is eliminated.

Even without the application of cold or heat required for the state to develop, the state can be stored and maintained in the normal temperature range, and the stored mode was required to develop the state. The color is changed to the original state by the reverse thermal means, and this is stored and stored in the normal temperature range.
