Abstract
Description
Technical Field
[0001] This invention relates to the field of textile fiber production technology, and in particular to a method for preparing blended seaweed yarn. Background Technology
[0002] The materials used in existing textiles and clothing are diverse, ranging from traditional cotton and animal hair to various synthetic fibers. Blended yarns are obtained by blending multiple fibers, and these yarns are then used to make fabrics, which in turn are finished garments. The texture or function of the finished garments depends on the materials used in the blended yarns. However, among the many categories of textiles and clothing, there are not many fabrics with antibacterial and anti-mite functions, especially fabrics made by adding natural fiber materials to blended yarns to create antibacterial and anti-mite fabrics.
[0003] Seaweed fiber is a natural functional fiber processed from sodium alginate. It is a non-toxic, harmless, and biodegradable green material. Fabrics, textiles, and clothing made from seaweed fiber are biodegradable. Furthermore, because seaweed fiber contains amino acids and minerals that are beneficial to the human body, fabrics made from this material have antibacterial and anti-mite properties. However, yarns blended with seaweed fiber lack smoothness, and the final antibacterial and anti-mite effects of fabrics made from this yarn do not reach an acceptable level. To address these issues, this application is hereby submitted. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention discloses a method for preparing blended seaweed yarn, comprising the following steps:

[0006] 2) Cleaning: Place the mixed cotton roll A into the cotton cleaning machine for mixing, opening, and removing impurities to obtain a mixed cotton roll B of standard length and weight;
[0007] 3) Carding: The mixed cotton lap B is placed in the opening machine and the carding machine in succession. After separation, impurity removal and mixing, a mixed fiber sliver is obtained.
[0008] 4) Drawing: The mixed fiber slivers are drawn together, then stretched by rollers and placed on the drawing sliver to be mixed into a sliver, thus obtaining a mixed fiber sliver;
[0009] 5) Roving: The mixed fiber sliver is shaped into rovings through drafting, twisting, and winding processes to obtain roving roux;
[0010] 6) Fine yarn: The roving roll is further processed through drafting, twisting, and winding to form fine yarn rolls;
[0011] 7) Automatic winding and packaging: The fine yarn roll is wound into yarn by an automatic winding machine, and yarn defects are removed and the yarn is wound into a bobbin to obtain seaweed blended yarn.
[0012] Specifically, in step 1), the other fibers are one or more of cotton, Modal, Tencel, silk, wool, nylon, and polyester.
[0013] Specifically, in step 3), the speed of the cotton opener is 350-400 r / min, and the fan speed is 650-700 r / min.
[0014] Specifically, in step 3), the carding machine cylinder speed is 200-260 r / min and the licker-in speed is 450-520 r / min.
[0015] Specifically, the seaweed blended yarn obtained by automatic winding and packaging in step 7) has a count of 60-80.
[0016] Specifically, during the preparation of the blended seaweed yarn, the working environment is maintained at a temperature ≥20℃ and a humidity of 60-65%.
[0017] Advantages and effects
[0018] The beneficial effects obtained by the technical solution of the present invention are as follows: the blended yarn method of the present invention can produce seaweed fiber blended yarn with a higher count, which has a smooth hand feel, and the fabric woven from this yarn has good antibacterial and anti-mite effects, providing a new option for making textile clothing with antibacterial and anti-mite functions. Detailed Implementation
[0019] The present invention will be further described below with reference to embodiments, but is not limited to the contents of the specification.
[0020] This invention relates to a method for preparing blended seaweed yarn, comprising the following steps:
[0021] 1) Preparation of blended fibers: Prepare 1-4 parts by weight of seaweed fiber and 6-9 parts by weight of fiber A, mix them and prepare blended cotton roll A; wherein, the seaweed fiber used has a specification of 1.65dtex*38mm, a strength of not less than 2.4cN / dtex, an alginate content of not less than 85%, and the color can be selected from colored or white seaweed fiber. In this invention patent, fiber A can be one or more of cotton, Modal, Tencel, silk, wool, nylon and polyester.
[0022] The seaweed fiber used in this invention requires a pretreatment step before blending with fiber A. The pretreatment involves soaking the seaweed fiber in a pretreatment agent for 30 minutes, maintaining the agent temperature at 60°C during soaking. Specifically, the pretreatment agent is added to the seaweed fiber, ensuring it completely covers the fiber. The temperature is then gradually increased until the mixture of the pretreatment agent and seaweed fiber reaches 60°C, which is maintained for 30 minutes. After soaking, the soaking solution is drained, and the seaweed fiber is centrifuged to remove excess water, ultimately obtaining pretreated seaweed fiber for blending with fiber A. Specifically, the pretreatment agent used in this step is a mixture of 39% lead acetate, 56% calcium chloride, and 5% calcium carbonate.
[0023] 2) Cleaning: The mixed cotton roll A is placed into the cotton cleaning machine for mixing, opening, and impurity removal to obtain a mixed cotton roll B of standard length and weight. The cleaning process requires four steps: opening, cleaning, mixing, and rolling. Opening loosens the compressed mixed cotton roll A into smaller cotton lumps or bundles, which is beneficial for the uniform mixing of fibers when using multiple mixed fibers, and also removes impurities.
[0024] The cotton cleaning process can remove most of the impurities, defects, and short fibers that are not suitable for blending into yarn from the mixed cotton roll A.
[0025] Cotton blending is used to fully and evenly mix various different fibers from multiple raw cotton rolls to improve the stability of the quality of yarn obtained from subsequent blending.
[0026] Rolling involves re-forming the mixed fibers that have undergone the above process into mixed fiber cotton rolls B with relatively uniform weight, length, thickness, and good shape, in order to facilitate subsequent processing steps.
[0027] This step requires the use of cotton blending machinery, such as automatic bale grabbers, and cotton box machinery, such as cotton box impurity removers and cotton boxes. It also requires manual machinery, such as cotton openers and single-pass cotton cleaners.
[0028] 3) Carding: The mixed cotton lap B is placed in the opening machine and carding machine in sequence. After sorting, impurity removal and mixing, a mixed fiber sliver is obtained. Specifically, in the carding process, the mixed cotton lap B needs to go through sorting, impurity removal, mixing and sliver forming processes in sequence. Among them, sorting can break down the cotton lumps of mixed fibers into a single fiber state and improve the straightness and parallelness of the fibers; impurity removal and mixing can further remove small impurities in the cotton lap and make the mixed fibers more evenly mixed; finally, sliver forming is to make the mixed fiber sliver into a mixed fiber sliver for subsequent processing steps.
[0029] This step requires the use of licker-in rollers, cylinder cover plates, and doffer machinery. The licker-in rollers initially straighten the mixed fibers, and the cylinder cover plates loosen the mixed fibers from the licker-in rollers into single fibers, achieving uniform mixing. After producing a high-quality mixed fiber layer, the doffer is transferred to the cylinder. The doffer can peel off the mixed fibers from the cylinder and aggregate them into a better cotton web. Through the pressure rollers and coiling devices on the doffer, a uniform mixed fiber sliver is produced.
[0030] Specifically, the opening machine uses a beater speed of 350-400 r / min and a fan speed of 650-700 r / min; the carding machine uses a cylinder speed of 200-260 r / min and a licker-in speed of 450-520 r / min.
[0031] 4) Drawing: The mixed fiber slivers are combined, then drawn by rollers and placed on the drawing sliver to be mixed into a sliver, thus obtaining a mixed fiber sliver. The purpose of drawing is to improve the uniformity of the sliver by combining and drawing the slivers again, and to further straighten the fibers so that the weight of each part of the sliver is uniform.
[0032] 5) Roving: The mixed fiber sliver is drawn, twisted and wound to form roving, which is then obtained as roving spool. Roving is mainly to lengthen and thin the mixed fiber sliver so that the diameter of the sliver meets the requirements of subsequent processing. At the same time, this process can also make the mixed fiber straighter.
[0033] 6) Fine yarn: The roving roll is further processed by drawing, twisting and winding to form fine yarn rolls; the fine yarn step increases the twist to maintain the tightness between fibers, increase the cohesion between fibers and improve the yarn strength.
[0034] 7) Automatic winding and packaging: The fine yarn spool is wound into a bobbin by an automatic winding machine to remove yarn defects and obtain seaweed blended yarn. The seaweed blended yarn has a count of 60-80. Winding and packaging is used to wind the bobbin into a large-capacity, well-formed bobbin with a certain density. An automatic winding machine can be used. The bobbinized seaweed fiber blended yarn is used for subsequent operations such as weaving. In addition, it should be noted that during the entire blended yarn process, the working environment in the workshop should be maintained at a temperature ≥20℃ and a humidity of 60-65%. Example 1

[0068] Comparative Example 3
[0069] This comparative example is basically the same as the implementation method of comparative example 2, except that the seaweed fiber used is the seaweed fiber in example 1.

[0076] Take the blended yarn rolls obtained from Examples 1-5 and Comparative Examples 1-4 above, use the same loom and the same warp and weft knitting method to obtain a total of 9 pieces of fabric with a size of 50*50 (cm), and conduct the following tests on the fabrics: 1) seaweed content test, and the smoothness results are shown in Table 1;
[0077] 2) Antibacterial performance test results are shown in Table 2;
[0078] 3) Anti-mite performance test results are shown in Table 3;
[0079] Table 1
[0080]
[0081] The seaweed yarn fabrics obtained in Examples 1-5 and Comparative Examples 1-4 were subjected to the following tests as shown in Table 2: Antibacterial performance test.
[0082] Test basis and method: FZ / T 73023-2006 Antibacterial Knitted Fabrics - Test for antibacterial properties.
[0083] Table 2
[0084]
[0085] The seaweed yarn fabrics obtained in Examples 1-5 and Comparative Examples 1-4 were subjected to the following tests listed in Table 3: anti-mite performance test.
[0086] Testing basis and methods: GB / T 24253-2009 "Evaluation of mite-proof performance of textiles"
[0087] Table 3
[0088]
[0089] During the research and development process, in order to increase the selection of textiles and clothing with a soft texture and antibacterial and anti-mite effects, this invention addresses this problem by starting with the yarn of textiles and clothing. The soft texture effect depends on the yarn count of the fabric. The higher the yarn count, the finer the yarn, and the better the softness. As shown in Comparative Example 1, in order to obtain antibacterial and anti-mite effects, chitosan fiber was added to the yarn during the spinning process for blending, and an 80-count blended yarn was produced. Fabrics and clothing were made using this yarn. As can be seen from the table, the fabric using this Comparative Example 1 blended yarn has a soft hand feel and good antibacterial and anti-mite effects. However, due to the high cost of chitosan fiber, the Comparative Example 1 blended yarn is not an optimal choice that is easy to promote and apply.
[0090] Given the high cost of chitosan fiber in Comparative Example 1, further research and testing of other natural materials were conducted, as shown in Comparative Example 2. It was discovered that seaweed fiber is also a natural functional material with good antibacterial and anti-mite properties (various natural fibers, such as flax and pineapple leaf fiber, were also collected and tested in this invention, but their performance was not good, so they will not be discussed further here). During the experiment, it was found that seaweed fiber is more brittle than chitosan fiber. Therefore, Comparative Example 2 selected to make 60-count yarn by adding seaweed fiber to the blended yarn. When testing the antibacterial and anti-mite properties of the fabric woven from this blended yarn, it was found, as shown in Tables 2 and 3, that the antibacterial and anti-mite performance of the fabric made from the blended yarn in Comparative Example 2 was not good. Further testing revealed, as shown in Table 1, that although seaweed fiber was added to this blended yarn, the seaweed content retained in the final fabric was significantly reduced compared to the amount of seaweed fiber added, and this reduction was higher than normal losses.
[0091] In subsequent research and development, to address the issue of significant seaweed loss, as shown in Comparative Example 3, this invention used seaweed fibers treated with a pretreatment solution. However, as can be seen from Tables 1, 2, and 3, although the seaweed loss problem was somewhat improved, the seaweed content of the seaweed fiber blended yarn in Comparative Example 3 was still unacceptable compared to the proportion of seaweed fiber added. Further research and testing on the pretreated seaweed fibers revealed that the pretreated seaweed fiber blended yarn performed better in terms of salt and alkali resistance than the untreated seaweed fiber blended yarn. This led to further research on the blended yarn's performance. Dyeing with dyes and pre-treated seaweed fiber yarns makes them easier to color. Microscopic observation revealed grooves on the cross-section of the pre-treated seaweed fibers. These grooves can further bind with other yarns during blending, reducing seaweed loss to some extent. Although grooves appeared on the cross-section of the seaweed fibers treated with the dye, their fiber strength was improved compared to untreated seaweed fibers. Here, fiber strength refers to tensile strength. The tensile strength test results of the pre-treated fibers showed that their strength was 1.5 times or more higher than that of the untreated fibers.
[0092] As can be seen from the table above and Examples 1, 2, 3, 4, and 5, using seaweed fibers pretreated with the pretreatment solution, combined with the blended yarn preparation process of the present invention, produces 60-count high-count yarn that can effectively improve the problem of seaweed loss and ensure a smooth feel for the yarn / fabric. With acceptable seaweed loss, 80-count high-count blended yarn can also be produced. Furthermore, the fabric made using the yarn from the examples exhibits good antibacterial and anti-mite properties. The blended yarn produced by this invention through this blending process provides an additional option for textiles and clothing that are soft, smooth, and effectively antibacterial and anti-mite.
[0093] Furthermore, through experiments and research during the development of the aforementioned seaweed fiber blended yarn, it was discovered that a solution prepared using a mixture of lead acetate, calcium chloride, and calcium carbonate can be applied to blended yarns and used for the pretreatment of fibers used in blended yarns. Specifically, the mixed solution of lead acetate, calcium chloride, and calcium carbonate can be used as a protective agent for seaweed fibers during the preparation of seaweed fiber blended yarns. In the subsequent complete blending process, it can reduce damage to seaweed fibers at various stages of spinning, such as damage from opening and carding of cotton and friction from the ring of the spinning spindle, and reduce cotton knot defects caused by spinning fly. This treatment addresses the issue of uneven yarn production and reduces the loss rate of seaweed fiber. Furthermore, seaweed fiber treated with the protective agent can achieve a wider range of colors in dyeing tests, from being able to dye only light colors to being able to dye dark colors evenly. The depth and vibrancy of the colors are also improved. Subsequent comparative tests on fibers used in blended yarns revealed that this solution, prepared using a mixture of lead acetate, calcium chloride, and calcium carbonate, also has a treatment effect on Modal and Tencel fibers. Blended yarns using Modal or Tencel as added fibers can also benefit from this treatment solution, improving subsequent dyeing and tensile strength.
[0094] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all embodiments here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
