Embodiment 1
[0038] A blended core-spun yarn used for gauze is made of the following raw materials in terms of mass percentage:
[0040] Spandex 20%
[0041] Cashmere 25%.
[0042] The production method comprises the steps of:
[0043] S1 mixing of raw materials: manually mixing 55% cellulose fibers and 25% cashmere fibers;
[0044] S2 spinning: combing, drawing, secondary drawing, sterilizing, and roving the blended raw materials mixed in step S1, and then core-spun with 20% spandex fiber, and then through the winding process to obtain the blended bag used for gauze core yarn.
[0045] Specifically, the carding process is as follows: the sliver output speed during carding is 450m / min, and the sliver output weight is 5-7g / m.
[0046] Specifically, the drawing process is as follows: the drawing speed is 160m / min, and the drawing weight is 5-7g / m.
[0047] Specifically, the sterilization process is: irradiating with ultraviolet light for 30 minutes.

Embodiment 2
[0050] A blended core-spun yarn used for gauze is made of the following raw materials in terms of mass percentage:
[0052] Spandex 15%
[0053] Cashmere 30%.
[0054] The production method comprises the steps of:
[0055] S1 mixing of raw materials: manual mixing of 55% cellulose fibers and 30% cashmere fibers;
[0056] S2 spinning: combing, drawing, secondary drawing, sterilizing, and roving the blended raw materials mixed in step S1, and then core-spun with 15% spandex fiber, and then through the winding process to obtain the blended bag used for gauze core yarn.
[0057] Specifically, the carding process is as follows: the sliver output speed during carding is 500m / min, and the sliver output weight is 5-7g / m.
[0058] Specifically, the drawing process is as follows: the drawing speed is 200m / min, and the drawing weight is 5-7g / m.
[0059] Specifically, the sterilization process is: irradiating with ultraviolet light for 40 minutes.

Embodiment 3
[0062] A blended core-spun yarn used for gauze is made of the following raw materials in terms of mass percentage:
[0064] Spandex 20%
[0065] Cashmere 20%.
[0066] The production method comprises the steps of:
[0067] S1 mixing of raw materials: manual mixing of 60% cellulose fibers and 20% cashmere fibers;
[0068] S2 spinning: combing, drawing, secondary drawing, sterilizing, and roving the blended raw materials mixed in step S1, and then core-spun with 20% spandex fiber, and then through the winding process to obtain the blended bag used for gauze core yarn.
[0069] Specifically, the carding process is as follows: the sliver output speed during carding is 550m / min, and the sliver output weight is 5-7g / m.
[0070] Specifically, the drawing process is as follows: the drawing speed is 180m / min, and the drawing weight is 5-7g / m.
[0071] Specifically, the sterilization process is: irradiating with ultraviolet light for 40 minutes.
