Embodiment Construction
[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0036] Such as Figure 1 to Figure 7 As shown, a method for preparing a high-elastic warm polyester composite yarn uses a kind of oiling equipment, the oiling equipment includes a bottom plate 1, a mounting plate 2, an oiling device 3 and a recovery box 4, and is prepared by the above-mentioned oiling equipment The specific method and flow of high elastic thermal insulation polyester composite yarn is as follows:
[0037] S1. Nascent fiber forming: use a melt spinning machine to extrude the raw materials mixed in proportion from the spinneret hole, and the polymer fine stream is solidified and formed in the spinning field to obtain a nascent fiber;
[0038] S2. Oiling of primary fibers: Use oiling equipment to cooperate with traction equipment to o...
