PET because PLA is more hydrophilic. Garments made from 100% PLA and blends of PLA with cotton feel more comfortable to the user [4]. In addition, the lower modulus leads to better properties of drape and hand-feel, while the crimp retention property leads to excellent crease resistance. Table 29.1 summarizes the comparison of the fiber/textile properties of PLA and PET [5, 6]. [Pg.470]

PLA fibers are also dyeable, using dispersion dyes (e.g., DENAPLA , Nagase Colors Chemicals Co., Ltd, Japan) at lower temperature, 100-110 C [7]. It is recommended that [Pg.470]
