In the small yellow ginger modified polyester fiber of the present invention, the base polymer component may be one or more selected from polyester, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide, polypropylene. In the context of the present invention, the polyamide may generally comprise polyamide 6 (PA 6), or polyamide 66 (PA 66).
For convenience of description and highlighting the essential features of the present invention, polyester is used as the base material in the following examples. It will be apparent to those skilled in the art that other corresponding materials may be used to accomplish the present invention.
In addition, in the manufacturing process to be described in the present invention, the process described in the embodiment may be included, and one or more processes for manufacturing a yarn or a twist known to those skilled in the art may be included in addition to the described process. Also, in alternative embodiments of the present application, the manufacturing method of the present application may be constituted by only the described manufacturing steps, excluding the presence of other steps.
The following describes the preparation of the (small) yellow Jiang Gaixing polyester fiber of the present invention and the preparation method thereof.
Example 1
Step 1) separation of turmeric cellulose from starch component
The yellow ginger is washed and then soaked in water for more than 30 hours, and in the embodiment, the soaking time is 72 hours. Experiments of the inventor show that the soaking can lead the cellulose in the turmeric to obtain sufficient moisture for swelling, and is beneficial to the subsequent compounding and bacteriostasis effect with the polymer aggregate. Crushing and grinding the turmeric by using a crusher after soaking to obtain turmeric slurry. Adding water (purified water) with the mass 5 times of that of the turmeric slurry, and sieving the turmeric slurry with water by using a mechanical vibrating screen to obtain the upper cellulose. To ensure a certain cellulose particle (or size), the sieving size is not too fine, and a 40 mesh sieve is used in this embodiment.
In the present invention, the fineness of the sieve is 30 to 50 mesh, preferably 35 to 45 mesh. The excessively fine mesh may result in undesirable strength of the final fiber when subsequently mixed with the polymer feed. If the mesh is too coarse, a rough feeling of roughness may be caused to the final fiber surface.
And (3) screening to obtain the turmeric cellulose reserved at the upper part of the screen holes, wherein turbid liquid below the screen holes is residual turmeric slurry, and the turmeric slurry contains turmeric starch and saponin.
Step 2): preparing a turmeric starch component: and (3) drying the residual turmeric slurry obtained in the step (1) by using a dryer to obtain a turmeric starch component. Grinding the starch component to obtain Curcuma rhizome starch component with particle size less than 80 mesh.
Step 3) preparing a base composition yarn: heating the terylene material to 260 ℃, and obtaining the turmeric cellulose according to the step 1): the polyester raw materials are mixed according to the ratio of 1:30 (mass ratio), the mixed raw materials are melted and extruded by extrusion equipment, and then the basic composition yarn is obtained through spinning, stretching, twisting and winding processes.
Wherein the twisting yarn process is performed in the range of 50 to 400TPM (twist per meter), preferably 150 to 300 TPM.
Step 4) preparing a yellow ginger starch composite bulked continuous polymer yarn (twisted): passing the base composition yarn of step 3) through a yarn heat treatment apparatus, blowing hot air to the yarn, and maintaining the yarn heat treatment apparatus at a temperature of about 150 ℃ to blow hot air of the same or similar temperature to the yarn. And simultaneously blowing the turmeric starch component in the step 2) to the yarn through a spray pipe, wherein the time for blowing the turmeric starch component and heating the turmeric starch component by hot air is 30 seconds, and the weight of the turmeric starch component accounts for 5 percent by weight of the total weight of turmeric cellulose and terylene materials, so as to prepare the bulked continuous polymer yarn (E1).
A schematic representation of the bulk continuous polymer yarn 10 produced in example 1 is shown in FIG. 1.
In the bulk continuous polymer yarn 10 produced, some wrinkling and fluffing of the twist of the yarn occurs, which is advantageous for the combination of the turmeric starch component and the twist in step 4).
Example 2
In embodiment 2, the same steps 1) to 3) as in embodiment 1 are performed. Unlike example 1, the following step 4) was performed:
passing the base composition yarn of step 3) through a yarn heat treatment apparatus, blowing hot air to the yarn, and maintaining the yarn heat treatment apparatus at a temperature of about 150 ℃ to blow hot air of the same or similar temperature to the yarn. Simultaneously blowing the turmeric starch component and a small amount of silane coupling agent KH550 in the step 2) to the yarn through a spray pipe, wherein the time for blowing the turmeric starch component and heating the hot air is 30 seconds, the mass of the blown turmeric starch component accounts for 5wt% of the total mass of turmeric cellulose and terylene materials, and the mass ratio of the turmeric starch component to the silane coupling agent is 10:1, so that the bulked continuous polymer yarn (E2) is obtained through blowing the air.
In example 2, a small amount of the silane coupling agent and the turmeric starch component are applied to the twisting surface of the bulked continuous polymer yarn together, so that a certain smooth twisting effect is achieved, and meanwhile, the silane coupling agent is helpful for increasing the fixing and bonding effects of the turmeric starch component and the twisting surface, and preventing the turmeric starch component from falling off prematurely in the use process of the bulked continuous polymer yarn.
Comparative example 1
Comparative example 1 ordinary twisted yarn was prepared using yellow Jiang Shaxian technology reported in the related art. Mixing commercial terylene raw material with commercial ground small yellow ginger powder (granularity is 60-80 meshes) according to terylene particles: mixing the small yellow ginger powder in a ratio of 28:1, heating to 260-270 ℃, carrying out melt extrusion on the mixed raw materials by using extrusion equipment, and then carrying out spinning, stretching and winding processes to obtain the composite yarn (C1).
Comparative example 2
In comparative example 2, the same procedure as in example 1 (wherein the mass ratio of turmeric cellulose to polyester raw material was 1:28) was carried out, except that step 4) was omitted, and the base composition yarn obtained in step 3) was used as a final product (C2).
Antibacterial test method
The examples and comparative examples E1, E2, C1, C2 of the present application determine the antimicrobial properties of different yarns according to GB/T20944.3-2008 "evaluation of antimicrobial properties of textiles". The results of the test are described in table 2.
Table 2: antibacterial effect of various strains of different yarns
From the table above, the combination of the distribution of (small) turmeric fibers in the polymer matrix and the distribution of turmeric starch particles on the fiber surface adopted in the manufacturing process of the invention further improves the antibacterial effect on the basis of higher antibacterial effect. At higher applied concentration of flora, the antibacterial effect of 98% or even more than 99% can be achieved. In contrast, the use of the related art scheme of mixing and melt-extruding the turmeric powder of C1 with the fiber matrix did not further improve the bacteriostatic effect of the turmeric active ingredient even though yellow Jiang Chengfen was distributed in the fiber in a slightly multicomponent ratio. While some progress was made in the C1 comparative test compared to the yellow ginger powder when the starch component was not blown with hot air and only the cellulose component was maintained in the C2 process, no improvement in antibacterial effect was achieved compared to examples E1 and E2, even when the content of the yellow ginger cellulose was slightly high.
For the above test of candida albicans, the corresponding preparation parameters in example 1/example 2 were varied, and candida albicans was further subjected to the corresponding test (inoculation concentration and species are the same), and the results are shown in table 3:
TABLE 3 antibacterial test results of modified Experimental examples of example 1 and example 2 on Candida albicans
E1.1 and E1.2 the same procedure as in example 1 was followed, except for the parameters indicated in the above table. Similarly, examples E2.1 and E2.2 used the same preparation process as E2, except for the parameters described above. As can be seen from the experiments in Table 2, when the soaking time of the turmeric in the step 1) is too short, the swelling degree of the turmeric fiber is insufficient, and the subsequent sterilization effect on candida albicans cannot be further improved. And when the soaking time exceeds 90 hours, improvement of the sterilizing effect is limited. In addition, when the screening of the fibers is too coarse or too fine, the physical properties of the yarn itself, such as breaking strength and surface feel, cannot be ensured.
The inventors do not wish to be bound by any theoretical explanation for the technical solutions and experimental conclusions of the present application. However, the (small) yellow Jiang Gaixing polyester fiber obtained by the process according to the invention has increased blowing of turmeric starch and/or a small amount of silane coupling agent in the heat treatment process for preparing the bulked continuous polymer yarn in addition to the turmeric cellulose incorporated inside the polymer substrate. Such a process not only makes full use of the turmeric raw material, but also can cause turmeric starch particles to adhere to the yarn (twisted surface) during the hot blowing process, forming adhered turmeric starch particles 11 (see schematic diagram of fig. 2). The starch has a certain adhesion effect on the surface of the polymer, and can be positioned on the yarn (twisting surface) for a long time under the composite action of the silane coupling agent, thereby playing a role in further long-term antibacterial and degerming.
Compared with the use of small yellow ginger powder or separate yellow ginger extract, the process for preparing the polymer fiber of the present application provides a brand-new manufacturing process for preparing yellow Jiang Gaixing fiber, further improves the problem that the antibacterial effect is difficult to further improve in the related art, and improves the raw material recycling and full utilization. Another additional explanation is that the antibacterial component contained in the turmeric starch component is higher, and the antibacterial component is respectively placed in the fiber and on the surface of the fiber by the process of separating yellow Jiang Zufen, so that the antibacterial effect is effectively improved. And simultaneously, the efficacy of the antibacterial raw materials is more fully utilized. Finally, in the bulked continuous yarn of the present invention, both the internal and external application of yellow Jiang Zufen can be better exhibited. The turmeric starch component attached to the surface of the bulked continuous yarn can be better combined with each of the twisted yarns.
