Descripition:
Thermochromic Hollow Crochet Yarn is an innovative yarn that changes color in response to temperature variations, combined with a lightweight hollow structure for enhanced comfort. As temperatures rise or fall, the yarn gradually shifts color, then returns to its original shade when conditions normalize.

Features:
1. Temperature-sensitive color-changing effect
2. Smooth texture for easy crochet and neat stitches
3. Durable color performance with stable thermochromic function
4. Comfortable and skin-friendly for wearable items
5. The yarn is less likely to come apart during crochet.

Precautions for Thermochromic Materials:
(1) Store in a dry and completely light-proof environment.
(2) Since the color-changing pigment is more stable in its colored state than in its faded state, varieties with lower color-change temperatures should be stored in a cool place. Prolonged storage at high temperatures may degrade their color-changing performance.
(3) Under the conditions mentioned above, the performance of most color-changing pigments shows no significant degradation after two years of storage.
(4) The processing temperature should be controlled below 150°C, and the heating time of the material should be minimized as much as possible. (High temperatures or prolonged heating will damage the pigment's color-changing properties.)
(5) Prolonged exposure to sunlight may degrade the color-changing performance.
(6) Customers are advised to conduct various tests with small samples before placing bulk orders to ensure suitability.
(7) Some color variation exists in functional threads, and even within the same batch, shades may differ.
(8) Do not wash with solvents.
