Embodiment 1
[0035] The polyester fiber elastic cloth for plaster of the present invention is made of polyester fiber (PET / PBT / PTT) as a raw material, and the following process is used for weaving and preparation;
[0036] 1 Detection of polyester fiber (PET / PBT / PTT) elastic yarn: detect polyester fiber (PET / PBT / PTT) elastic yarn, determine where PET-polyethylene terephthalate (Polythylenerephthalate), PBT - The proportion of polybutylene terephthalate (polybutyleneterephthalate) and PTT-polytrimethylene-terephthalate (polytrimethylene-tereph-thalate) meets the requirements;
[0037] II Weaving: knitting a number of qualified weft yarns (elastic yarns) to form "flat stitch" or "Ω" shape, but not limited to elastic cloth with "flat stitch" texture, and ironing;
[0038] III Impurity removal: In the 100,000-class clean area, the woven elastic fabric is pulled through two vacuum cleaners with a power of 4kw and two suction heads, both of which are equipped with upper and lower suction heads, ...
Embodiment 2
[0045] Embodiment 2, basic technique is the same as embodiment 1, but sterilization temperature is 54~58 ℃, and sterilization time is 4 hours.
