Embodiment 1

[0038] A blended core-spun yarn used for gauze is made of the following raw materials in terms of mass percentage:

[0039] Cellulose Fiber 55%

[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:

[0051] Cellulose Fiber 55%

[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:

[0063] Cellulose Fiber 60%

[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.

Abstract

The invention relates to a blended core-spun yarn for gauze and a manufacture method thereof. The blended core-spun yarn is made from, by mass, cellulose fibers 45-65%, spandex fibers 10-20% and cashmere fibers 20-30%. The manufacture method includes the following steps: S1, raw material mixing: artificially mixing the cellulose fibers and the cashmere fibers; S2, spinning: carding blended raw materials obtained in the step S1, drawing, performing secondary drawing, sterilizing, processing to obtain roving, and conducting core spinning together with the spandex fibers; spooling to obtain the blended core-spun yarn for the gauze. The blended core-spun yarn has the advantages of low cost, simple process, excellent yarn quality and low microbial residue.

Description

technical field [0001] The invention relates to the technical field of blended textiles, in particular to a blended core-spun yarn used in gauze and a manufacturing method thereof. Background technique [0002] The spinning process is a method of processing raw materials for spinning. It is a key factor affecting the quality of yarn and cloth. But for the blended yarn of cashmere fiber and chemical fiber, the quality of the blended raw materials will affect the smooth realization of the subsequent spinning process to varying degrees, and more importantly, the blending ratio of the yarn. [0003] In order to provide more and more comfortable textile materials for the field of knitted garments and reduce production costs, in recent years, the market has introduced a series of wool cashmere fiber (or wool viscose) yarns, the common ones are 45 / 55, 30 / 65 and 20 / 80 and other specifications of blended yarn. Because the wool component in the blended yarn is not resistant to stro...
