Abstract
A processing method of lyocell yarn with a slow-release function of wormwood microcapsules belongs to the technical field of yarn processing. The method comprises the steps of sequentially guiding the lyocell yarn which is withdrawn from a lyocell yarn bobbin arranged on a bobbin creel to carry out low-temperature plasma treatment by a low-temperature plasma generator, carrying out corona treatment by a corona generator and carrying out padding treatment by a padding tank which takes a mugwort essential oil microcapsule dispersing agent aqueous solution as padding liquid, discharging the padded solution from the padding tank after the padding treatment is finished, guiding the padded solution into a drying device to dry, and winding the padded solution on a winding bobbin by the drying device to obtain the lyocell yarn with a mugwort microcapsule slow-release function. The advantages are that: the formation of a stiff cross-linking layer on the surface of the lyocell yarn is avoided, the excellent handfeel flexibility and the wearing comfort are reflected, the washability is ideal, the slow release function of the wormwood microcapsule is permanently kept, the moisture absorption and ventilation can be reflected, and the excellent biodegradability is reflected after the wormwood microcapsule is discarded.
Description
Technical Field
The invention belongs to the technical field of yarn processing, and particularly relates to a processing method of lyocell yarn with a slow-release function of mugwort microcapsules.
Background
The 'over the sky' is common to people, and the current yarns are mainly three types from the major categories, namely pure natural fiber yarns; secondly, pure chemical fiber yarn; thirdly, the yarn is obtained by blending natural fibers and chemical fibers. Along with the continuous improvement of the living standard of people and the continuous enhancement of health consciousness and green environmental consciousness, the functional pursuit factors for various fabrics are increasingly abundant. Among them, the fabric processed by the lyocell yarn with the slow-release function of the wormwood microcapsule and the clothing made of the fabric are favored by people.
The prior art method for processing the lyocell yarn with the active ingredients of the wormwood mainly comprises the following two steps: firstly, mixing active ingredients of wormwood such as wormwood essential oil microcapsules into lyocell fibers to form yarns; secondly, using the auxiliary agent and dye added with the active ingredients of the mugwort, such as the mugwort essential oil microcapsule, as working fluid, and dyeing by a yarn dyeing machine and/or padding treatment by a yarn padding device, so that the auxiliary agent forms a cross-linked film on the surface of the yarn or in the fiber. The former mode of the two modes has the advantages of high processing efficiency, convenience, rapidness and the like, but the effective components of the wormwood are difficult to release slowly and even can not meet the expected requirements of the industry. The latter of the two approaches is lacking in that: firstly, in order to fix or bind the functional substances, particularly the water-insoluble substances, to the surface of the yarn as well as possible, the amount of the crosslinked resin is large, and the formation of a large amount of the crosslinked resin on the surface of the yarn seriously affects the softness of the hand of the fabric after the fabric is processed from the yarn; secondly, as eupatilin is used as an important flavonoid active ingredient of the wormwood, and as the eupatilin can only be adhered between the surface of the fabric and the fiber and does not penetrate into the fiber, the eupatilin has poor washing fastness, namely the function is reduced or even lost due to easy elution; thirdly, as a layer of stiff cross-linked film is formed on the surface of the fabric, the hygroscopicity and the air permeability of the fabric are affected, and particularly, the too thick and stiff cross-linked film formed on the surface of the fabric can affect the rapid exchange and the passing of water molecules and gas molecules, so that the hygroscopicity and the air permeability are seriously reduced. In view of this, how to make up for the above-mentioned deficiency and make the lyocell yarn achieve both the excellent slow release function of the mugwort microcapsules (i.e. "mugwort essential oil microcapsules", hereinafter the same) and the advantages of exhibiting ideal softness of touch and wet permeability after being processed into a fabric, the technical problems that are considered in the industry and are desired to be solved are achieved, and the technical solutions to be described below are created under such a background.
Disclosure of Invention
The invention aims to provide a processing method of lyocell yarn with a slow-release function of mugwort microcapsules, which can enable eupatilin which is an important active ingredient of flavonoids of mugwort to permeate into the lyocell fiber, and can prevent the eupatilin from forming an excessively stiff cross-linked layer on the surface of the fabric after being processed into the fabric, so that good handfeel softness is reflected, comfort, ideal washing resistance and good durability of the slow-release function of mugwort microcapsules are reflected after the fabric is processed into clothes, and excellent hygroscopicity and air permeability are reflected.
The invention discloses a processing method of lyocell yarn with a slow-release function of a Chinese mugwort microcapsule, which comprises the steps of sequentially guiding the lyocell yarn which is withdrawn from a lyocell yarn bobbin arranged on a creel to be subjected to low-temperature plasma treatment by a low-temperature plasma generator, carrying out corona treatment by a corona generator, carrying out padding treatment by a padding tank which takes a Chinese mugwort essential oil microcapsule dispersing agent aqueous solution as padding liquid, discharging the padding tank after the padding treatment is finished, introducing the padding tank into a drying device for drying, and winding the padding tank with the lyocell yarn with the slow-release function of the Chinese mugwort microcapsule by a discharging drying device.
In a specific embodiment of the invention, the yarn is withdrawn from the lyocell yarn bobbin to a travel speed of 20-100m/min during winding from the winding bobbin.
In another specific embodiment of the present invention, the lyocell yarn is composed of lyocell filaments or lyocell staple fibers having been previously desized and fibrillated and having a pH of 6 to 8 and a fineness of 20 to 500D, or having a count of 10 to 80S.
In another specific embodiment of the present invention, the low temperature plasma treatment performed by the low temperature plasma generator means low temperature plasma treatment, wherein the voltage of the low temperature plasma treatment is 50-200V, and the current is 1-2A; the voltage of the corona generator in the corona treatment is 2000-5000V and the power is 5-100W.
In still another specific embodiment of the present invention, the padding tank is a spray padding tank, the padding means that the yarn sprayed with the aqueous solution of the wormwood essential oil microcapsule dispersing agent as the padding liquid passes through one or a plurality of pairs of padding rollers, and the padding pressure of the padding rollers is controlled to be 0.15-0.3MPa.
