| titleOfInvention | Preparation method of thermochromic non-woven fabric |
| abstract | The invention relates to the technical field of non-woven fabrics, and provides a preparation method of a thermochromic non-woven fabric, which solves the problems that the temperature resistance requirement of a color-changing agent required for preparing a thermochromic fiber is high, the durability of the prepared thermochromic fiber is reduced, and the hand feeling of the prepared thermochromic fiber is poor in the prior art, and comprises the following steps of: (1) taking thermosensitive color-changing fibers and common ES fibers as raw materials of the thermosensitive color-changing non-woven fabric; the thermochromic fiber is of a sheath-core structure and comprises a sheath layer and a core layer, wherein the sheath layer comprises the following raw materials in parts by weight: 0.8-3 parts of a color former, 1-30 parts of a color developing agent, 30-90 parts of polyethylene glycol 1500 and 60-100 parts of polyethylene, wherein the core layer is polyethylene terephthalate; (2) respectively opening and mixing the thermochromic fibers and the common ES fibers, carding, bonding by hot air, and cooling and shaping to obtain a first non-woven fabric and a second non-woven fabric; (3) and (3) compounding the first non-woven fabric and the second non-woven fabric which are prepared in the step (2) on line. |
