Embodiment 1
[0031] The invention provides a preparation process of a wash-free regenerated polyester blanket, which mainly includes: raw material selection, weaving, presetting, printing, finishing and finished product production. The specific process is as follows:
[0032] (1) In order to ensure the quality of the yarn, the raw materials are selected as follows:
[0033] Veil: Use recycled polyester DTY with a monofilament fineness of 3.125D,
[0034] Bottom yarn: 150D / 36F recycled polyester FDY,
[0035] By weight percentage: veil 79% and ground yarn 21%.
[0036] (2) Raschel double-needle-bar warp knitting machine is used for weaving. The stripping distance of the double-needle-bar warp knitting machine is 18mm, the wool height is 6mm, the needle size is E18, and the gray fabric weight is 750g / m 2 .
[0037] (3) Pre-finishing process: pre-baking → brushing → pre-scalding → brushing → pre-scalding
[0038] The pre-drying temperature is controlled at 130°C, and the cloth speed is 1...
