Description

Technical Field

[0001] The present application relates to the technical field of textile material preparation, and in particular to a method for preparing camel hair antibacterial yarn and the camel hair antibacterial yarn. Background Art

[0002] Camel hair is elastic, not easy to shrink, and has a smooth surface. The products made from it are light, soft, comfortable and warm. However, camel hair itself has a darker color (brown yellow, i.e. camel color), which makes the products processed from it monotonous in color and single in variety, making the added value of camel hair products low. Moreover, camel hair, as a protein-based fiber raw material, is prone to mildew and insect damage.

[0003] Existing camel hair fibers are prone to mildew and insect damage, their yarns are monotonous in color, and their antibacterial rates against Staphylococcus aureus and Escherichia coli cannot reach 99.9%.

The inoculated circular plates were then incubated at 37°C overnight.

[0057] The visible colonies on the circular plates were counted, and the bacterial survival rate after illumination was determined by the ratio of the colony counts on the circular plate of the light-irradiated antibacterial yarn to the colony count on the circular plate of the colony blank.

[0064] In this embodiment, the content of the photosensitizer Rose Bengal is no less than 3% owf.

[0065] The present application is further described in detail below by way of examples. It should be understood that the examples do not constitute any limitation to the present application.

[0066] The preparation method of camel hair antibacterial yarn includes:

[0078] In this embodiment, it can be obtained from the Kubel-Kamunck (KM) theory:

[0079] Where: (K / S)λ is the ratio of the absorption coefficient to the scattering coefficient of the fiber at wavelength λ; R λ is the reflectivity of the fiber at a certain wavelength.

[0080] In this embodiment, the K / S value of the mixed color fiber at a wavelength interval of 5 nm from 400 nm to 700 nm has the following relationship with the K / S value of the single color fiber:

[0081] (K / S) λ =C1(K / S) λ +C2(K / S) λ +…+C n (K / S) λ (Formula 1-2)

[0082] C1+C2+…+C n =1 (Formula 1-3)

[0083] Where: (K / S) λIt is the ratio of the absorption coefficient to the scattering coefficient of the mixed-color fiber and the single-color fiber at a certain wavelength; C is the proportion of single-color fiber in the mixed-color fiber.

[0084] In this embodiment, it is found through testing that, under the wavelength conditions to be used, by testing the various K / S values ​​of the third camel hair fiber bundle at different photosensitizer concentrations, the K / S value corresponding to the minimum photosensitizer concentration that can make the antibacterial rate of the mixed fiber against Staphylococcus aureus and Escherichia coli reach 99.9% is obtained. In this embodiment, when the K / S value is greater than 25 at 560nm, the antibacterial rate of the fiber against Staphylococcus aureus and Escherichia coli reaches 99.9%.

[0085] In this embodiment, the proportional relationship between the three fiber bundles is obtained based on the K / S values ​​of the three fiber bundles measured in S1, as well as Formula 1-1, Formula 1-2, Formula 1-3 and the mixed fiber K / S value of 25:

[0086]

[0087] Wherein, C1 represents the first camel hair fiber bundle, C2 represents the second camel hair fiber bundle, and C3 represents the third camel hair fiber bundle.

[0088] In this embodiment, the testing of the K / S value of the third fiber bundle when loaded with the photosensitizer Rose Bengal at different concentrations, the testing of the antibacterial performance of the third fiber bundle at different K / S values, and the obtaining of the K / S value corresponding to the lowest photosensitizer concentration at which the antibacterial performance reaches 99.9% include:

[0089] S1. Set up three parallel groups, put the antibacterial yarn (about 30 mg) into 24-well plates, add 100 μl of 10 4 -10 5 CFU / ml of bacterial solution, 100 μl of bacterial solution was also added to the three adjacent blank wells as blank samples. After inoculation, the 24-well plate was illuminated for a certain period of time under a xenon lamp (300 W) equipped with a filter (λ ≥ 420 nm) at a distance of 20 cm from the sample;

[0090] After illumination, add 900 μL of autoclaved PBS (phosphate-buffered saline) to each well of a 24-well plate and manually agitate for 10 seconds to resuspend the bacteria. Subsequently, dilute the bacterial solution from each sample five times at a 1:10 ratio (add 100 μL of the solution to the next dilution gradient of 900 μL of PBS). Scrape 100 μL of the solution from each gradient onto a circular plate (using LB-agar medium) and incubate the inoculated circular plates overnight at 37°C.

[0091] S3. Count the visible colonies on the circular plates. The bacterial survival rate after illumination is determined by the ratio of the colony counts on the circular plate with the antibacterial yarn to the colony count on the circular plate with the blank sample.

[0092] In this embodiment, preparing the first camel hair fiber bundle includes: washing the camel hair fibers in 50° C. water three times to obtain the first fiber bundle.

[0093] In this embodiment, making the second camel hair fiber bundle includes: chemically bleaching the camel hair fibers into bleached camel hair fibers, namely the second fiber bundle;

[0094] In this embodiment, the preparation of the third camel hair fiber bundle includes: dyeing the decolorized fiber surface with the photosensitizer Rose Bengal and the groups on the fiber through the action of covalent bonds, thereby dyeing the third fiber bundle.

[0095] In this embodiment, the content of the photosensitizer Rose Bengal is not less than 3% owf.

[0096] In this embodiment, using a drawing frame to straighten and parallelize the fibers inside the mixed fiber includes:

[0097] A drawing frame is used to straighten and parallelize the fibers, and at least three blending processes are used to fully mix them and reduce color difference.

[0098] In this embodiment, the camel hair antibacterial yarn is obtained through the roving and spun yarn processes, including:

[0099] Yarn is obtained through coarse yarn and fine yarn processes; the coarse yarn adopts the process principle of "heavy pressure, small rear zone drafting, and large twist coefficient", appropriately reduces the machine speed, and the process configuration concentrates on the front zone drafting to facilitate the control of floating fibers and improve the yarn quality; the fine yarn uses a larger twist coefficient to increase the density of the yarn in the spinning section, reduce the twisting triangle area, control the temperature and humidity in the workshop, reduce the yarn hairiness, and improve the yarn strength.

[0100] In this embodiment, camel hair fibers are treated by chemical bleaching. During this process, the whiteness of the fibers is improved and the strength is reduced. By optimizing the bleaching process, the damage to the fiber strength during this process is reduced.

[0101] When the third fiber bundle is loaded with the photosensitizer Bengal rose red, the photosensitizer can combine with the fiber surface groups through van der Waals forces and hydrogen bonds under weakly acidic conditions, thereby being loaded on the camel hair fiber, giving the second fiber bundle antibacterial properties under visible light. The loading ratio is not less than 3% owf, thereby ensuring the antibacterial effect of the fiber bundle.

[0102] The proportions of the first fiber bundle, the second fiber bundle, and the third fiber bundle in the mixed fiber are calculated using the KM theory.

[0103] The present application also provides a camel hair antibacterial yarn, which is prepared by the camel hair antibacterial yarn preparation method as described above.

[0104] The present invention loads the photosensitizer on the fiber by combining it with the fiber surface groups through van der Waals forces and hydrogen bonds, giving it the ability to effectively resist bacteria and other microorganisms on the yarn surface under visible light. It is made by blending three fibers of different colors, which not only ensures the antibacterial effect but also softens the overly bright color caused by the photosensitizer in the yarn.
