Description

Technical Field

[0001] This invention relates to the field of fabric textiles, and in particular to a method for making fabrics using seaweed fibers. Background Technology

[0002] 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 have biodegradability. Furthermore, because seaweed fiber contains beneficial amino acids and minerals, fabrics made from this material have antibacterial and anti-mite properties. However, seaweed fiber has relatively low strength and is too slippery, making it brittle in terms of physical properties. This leads to the loss of seaweed fiber during the blending process into yarn. While 40-count seaweed fiber blended yarns are commonly used, even 40-count yarns will lose 3%-5% of their seaweed content. Higher count yarns are finer and produce smoother fabrics, but very fine yarns are difficult to produce and break easily, especially seaweed fiber blended yarns, which are inherently brittle. This makes it difficult to spin high-count yarns of 60 count or higher, limiting the smoothness of garments made from this fiber. Furthermore, seaweed fiber is not resistant to salt and alkali treatment and easily gels in solutions containing sodium ions, making dyeing difficult. All these drawbacks affect and limit the application areas of seaweed fiber. In conclusion, creating a method to weave seaweed fibers into high-count yarns of 60 count and above, while ensuring the dyeing and colorfastness of the fabric, is an urgent problem to be solved. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention discloses a method for manufacturing fabric using seaweed fibers, comprising the following steps: A) Blended yarn: Take seaweed fiber and other fibers, and blend them through the following processes: blending, opening, carding, drawing, roving, spinning and automatic packaging to obtain blended seaweed yarn. B) Fabric weaving: Take the blended seaweed yarn obtained in step A) and weave it using a knitting machine to obtain seaweed yarn fabric; C) Fabric pre-forming: The fabric woven in step B) is pre-formed in a pre-forming device at a temperature of 175-190℃ and a speed of 20-22 meters / minute to obtain a pre-formed seaweed yarn fabric. E) Fabric washing: Place the pre-shaped seaweed yarn fabric in the washing tub and wash it with a neutral soap detergent. F) Fabric setting: Take the seaweed yarn fabric that has been washed in step E), introduce the opened fabric joints into the machine, set and dry it, and obtain the finished seaweed yarn fabric after setting.

[0004] Furthermore, after the fabric is pre-shaped in step C), it also includes a dyeing step D. D) Fabric dyeing: The seaweed yarn fabric obtained in step C) is dyed using a one-bath dyeing method. The pH value of the dye bath is controlled at 6.5-7.5, the dye bath temperature is maintained at 85℃, and the dyeing is continued for 30 minutes to complete the dyeing process and obtain the dyed seaweed yarn fabric. E) Fabric washing: Place the dyed seaweed yarn fabric in a washing tub and wash it with a non-alkaline soap. F) Fabric setting: Take the dyed seaweed yarn fabric that has been washed in step E), introduce the opened fabric joint into the machine, set and dry it, and obtain the finished seaweed yarn fabric after setting.

[0005] Specifically, the dyed seaweed yarn fabric obtained in step D) needs to be washed to remove residual water. Take the dyed seaweed yarn fabric and wash it with water at a temperature of 60°C for a duration of ≥20 minutes until there is no residual oil or floating color.

[0006] Specifically, in step A), the seaweed fiber is 1-4 parts, and the other fibers are 6-9 parts. The other fibers are one or more of cotton, Modal, Tencel, silk, wool, nylon, and polyester. The blended seaweed yarn of the blended belt is a high-count yarn of not less than 60 count.

[0007] Specifically, in step A), when performing carding operation on the blended fibers, an opener and a carding machine are used. The opener's beater speed is ≤400r / min, the fan speed is ≤700r / min, the carding machine's cylinder speed is ≤260r / min, and the licker-in roller speed is ≤520r / min.

[0008] Specifically, in step B), during the process of knitting the seaweed yarn fabric, the ambient working temperature is maintained at 22-25℃, the relative humidity is maintained at 90-95%, and the weaving machine is used at a speed of 10-14 r / min for weaving.

[0009] Specifically, in step C), the fabric pre-forming temperature is 175-190℃, and the machine speed is 20-22 meters / minute.

[0010] Specifically, in step F), the fabric setting and drying temperature is 120℃, and the fabric conveyor speed is 14-16 meters / minute.

[0011] Specifically, before dyeing the fabric in step D), the pre-shaped seaweed yarn fabric needs to undergo a pretreatment step. The pretreatment step involves washing the seaweed yarn fabric with a refining agent of 2-5 g / L and a pH controlled at 7-7.5 to remove oil and impurities.

[0012] Furthermore, a high-count yarn fabric using seaweed fiber is obtained through the above manufacturing method.

[0013] Advantages and effects

[0014] This invention fully preserves the natural characteristics and functions of seaweed fiber, overcomes the difficulties in yarn production and dyeing, and can produce high-count blended yarns of 60 count and above and high-count seaweed yarn fabrics. It can also control the seaweed loss in the final yarn to about 3%, and at the same time, it can not affect the seaweed content and fabric performance of the high-count seaweed yarn fabric after dyeing. Attached Figure Description

[0015] Figure 1 This is a flowchart illustrating the fabric preparation process for this invention. Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments, but is not limited to the contents of the specification.

[0017] This invention relates to a method for manufacturing fabric using seaweed fibers, which includes the following steps: A) Blended yarn: 1-4 parts by weight of seaweed fiber (1.65 dtex * 38 mm, strength 2.6 cN / dtex, alginate content not less than 85%) and 6-9 parts by weight of cotton are used. The blending process involves cotton blending, opening, carding, drawing, roving, spinning, and automatic can packaging. During carding, an opener and a carding machine are used. The opener beater speed is 350-400 r / min, the fan speed is 650-700 r / min, and the carding machine cylinder speed is 2... The carding operation is performed at a speed of 00-260 r / min and a licker-in speed of 450-520 r / min, ultimately producing a 60-count high-count blended seaweed yarn. The carding intensity needs to be carefully controlled during the blending process, employing a light, slow, and gentle carding process. It is important to maintain a spinning workshop temperature above 20℃ and a humidity of 60-65% during the operation. The seaweed fiber used is sourced from seaweed fiber developed by Qingdao Yuanhai New Material Technology Co., Ltd.

[0018] Alternatively, seaweed fibers can be blended with one or more of cotton, Modal, Tencel, silk, wool, nylon, and polyester to produce blended seaweed yarn. For raw material selection, colored or white seaweed fibers can be used. The other blended fibers must meet or exceed the following fineness: wool diameter not higher than 19.5 microns, Modal not higher than 0.9D, and silk not higher than 1.3D. If the fiber fineness and strength cannot meet the diameter requirements, high-count blended seaweed yarn of 60 count or above cannot be spun.

[0019] The seaweed fiber content used in the blending process is generally between 10% and 40%, while the content of blended fibers such as cotton, modal, and wool is between 60% and 90%. This is because seaweed fiber is relatively slippery and brittle. If the content is too high, the yarn will have poor spinnability and excessive spinning loss.

[0020] B) Fabric weaving: The blended seaweed yarn obtained in step A) is woven using a circular knitting machine at an ambient temperature of 22-25℃ and an ambient humidity of 90-95% at a speed of 10-14 r / min to obtain seaweed yarn fabric. The humidity has a significant impact on the yarn weaving process. Seaweed fibers are relatively brittle and slippery. Weaving under the working environment of this application can reduce fiber fly and reduce fabric defects. At the same time, it is necessary to increase the cleaning frequency of the loom during the weaving process to ensure the weaving quality. Knitting can be carried out using various machines such as single-sided circular knitting machines, double-sided circular knitting machines, rib knitting machines, jacquard knitting machines, small circular knitting machines, flat knitting machines, and Santoni seamless knitting machines. In this process, not only can a single blended seaweed yarn be used for knitting, but other yarns can also be added for knitting, including but not limited to spandex. Finally, different knitting machines can be used to obtain different types of fabrics, such as partially or fully biodegradable single-sided fabrics, double-sided fabrics, rib fabrics, jacquard fabrics, small circular knitting machines, seamless integrated fabrics, and flat knitting machine fabrics. Among them, the blended seaweed yarn used in Santoni seamless knitting machines adopts S / Z double twist yarn to balance the twist of the fabric. This allows the seaweed short fiber blended yarn to interweave with the chemical fiber filaments, combining long and short fibers. The final fabric is skin-friendly on one side and dry on the other, and the fabric can achieve the effect of moisture absorption and perspiration wicking.

[0021] In addition, the yarn can be arranged according to the fabric's structure and the finished product's function. Taking the use of the Santon seamless knitting machine as an example, the blended seaweed yarn uses S / Z double twist yarn to balance the fabric's twist. The short fiber blended yarn and chemical fiber filaments are interwoven to form a seaweed short fiber yarn on one side, which is skin-friendly and breathable, and a chemical fiber filament on the other side, which is dry and quick-drying. The fabric can achieve the effect of moisture absorption and perspiration wicking. Other types of yarn arrangement designs can be used with different knitting machines and different weaving methods as needed.

[0022] C) Fabric pre-forming: The fabric woven in step B) is pre-formed in a pre-forming device at a temperature of 175-190℃ and a speed of 20-22 meters / minute to obtain a pre-formed seaweed yarn fabric. Pre-forming can ensure the balance of the fabric before washing or dyeing. Specifically, fabric balance here refers to the tension in the yarn during fabric weaving, which may result in uneven stress after the greige fabric comes off the machine. Pre-forming removes the uneven tension in the greige fabric and ensures the dimensional stability of the fabric.

[0023] E) Fabric washing: Place the pre-shaped seaweed yarn fabric in a washing tank and wash it at a washing solution temperature of 60℃ for 20 minutes to complete the washing. The washing is used to remove residual chemical agents and oil stains from the fabric.

[0024] F) Fabric setting: Take the seaweed yarn fabric that has been washed in step E), introduce the opened fabric splice into the machine, and set and dry it. During the drying process, set the drying temperature to 120℃ and the machine speed to 15 meters / minute. After setting, the finished seaweed yarn fabric is obtained. In order to ensure the continuity of setting, the fabric to be set is introduced into the setting machine through the fabric splice. Specifically, the setting is a winding flat setting.

[0025] The above steps are applicable to the production of seaweed yarn fabric woven from undyed or colored yarn fibers. To obtain dyed seaweed yarn fabric, the following dyeing steps are also required: After step C) of the above operation steps, proceed to step D) of the fabric dyeing step: The seaweed yarn fabric obtained in step C) is dyed using a bath dyeing method. The pH value of the dye bath is controlled at 6.5-7.5, the dye bath temperature is maintained at 85℃, and the dyeing is continued for 30 minutes to complete the dyeing process and obtain the dyed seaweed yarn fabric. Then, the dyed seaweed yarn fabric is washed to remove residual water. The dyed seaweed yarn fabric is then washed with water at a temperature of 60℃ for a duration of ≥20 minutes until there is no residual oil or floating color. During the bath dyeing process, the pH value is controlled by using an acid-releasing agent, the specific amount of which varies depending on the water quality.

[0026] Additionally, it should be noted that, in order to further ensure the dyeing quality and maintain the stability of the seaweed fiber during the dyeing process, a pretreatment step must be performed on the pre-shaped seaweed yarn fabric before dyeing. The pretreatment step involves washing the seaweed yarn fabric with a refining agent of 2-5 g / L and a pH controlled at 7-7.5 to remove oil and impurities.

[0027] E) Fabric washing: Place the dyed seaweed yarn fabric in a washing tub and wash it with a neutral soap detergent; the neutral soap detergent here includes, but is not limited to, AASK neutral soap detergent for Ya Yun cotton.

[0028] F) Fabric setting: Take the dyed seaweed yarn fabric that has been washed in step E), introduce the opened fabric joint into the machine, set and dry it, and obtain the finished seaweed yarn fabric after setting.

[0029] The seaweed yarn fabric produced by the above weaving method can be used in the production of underwear, sweaters, socks and other woven fabrics.

[0030] The resulting seaweed yarn fabric fully retains the natural characteristics and functions of seaweed fibers, and overcomes the problems of high seaweed yarn loss and low seaweed content in the finished yarn when producing high-count blended yarn of 60 count or above. It retains its biodegradable and environmentally friendly properties. If interwoven with biodegradable spandex, it can obtain a fully or partially biodegradable fabric. Example 1

[0031] The seaweed yarn fabric is produced by following steps A through F above. The specific process parameters used are as follows: In step A), 4 parts seaweed fiber and 6 parts cotton are taken from the blended yarn. During the carding stage, the opening machine beater speed is 400 r / min, the fan speed is 700 r / min, the carding machine cylinder speed is 260 r / min, and the licker-in speed is 520 r / min. During the operation, the humidity in the spinning workshop is kept at 60%. B) During the fabric weaving process, the ambient temperature is maintained at 22℃, the relative humidity is maintained at 90%, and the weaving machine is used at a speed of 14r / min. C) Fabric pre-forming is carried out at a temperature of 190℃ and a machine speed of 20 meters per minute. After completing the subsequent steps, the seaweed yarn fabric is obtained. Example 2

[0032] This embodiment is basically the same as Embodiment 1, except that after the fabric is pre-shaped in step C), a dyeing step is also performed on the blended seaweed yarn fabric. D) Fabric dyeing: The seaweed yarn fabric obtained in step C) is dyed using a one-bath dyeing method. The pH value of the dye bath is controlled at around 6.5-7.5, the dye bath temperature is maintained at 85℃, and the dyeing is continued for 30 minutes to complete the dyeing process and obtain the dyed seaweed yarn fabric. E) Fabric washing: Place the pre-shaped seaweed yarn fabric in the washing tank and wash it at a washing solution temperature of 60℃ for 20 minutes to complete the washing. F) Fabric setting: Take the dyed seaweed yarn fabric that has been washed in step E), introduce the opened fabric joint into the machine, and set and dry it. During the drying process, set the drying temperature to 120℃ and the machine speed to 15 meters / minute. After setting, the finished seaweed yarn fabric with color is obtained. Example 3

[0033] This embodiment uses the same steps as Embodiment 1, but employs different production conditions or parameters to produce the finished seaweed yarn fabric. Specifically, the differences are as follows: In step A), 2 parts of seaweed fiber and 8 parts of Tencel, silk, wool, nylon and polyester are taken from the blended yarn. During the carding stage, the opening machine beater speed is 350 r / min, the fan speed is 650 r / min, the carding machine cylinder speed is 200 r / min and the licker-in speed is 450 r / min. During the operation, the humidity in the spinning workshop is maintained at 65%. B) During the fabric weaving process, the ambient temperature is maintained at 25℃, the relative humidity is maintained at 95%, and the weaving machine is used at a speed of 10r / min. C) Fabric pre-forming is carried out at a temperature of 175℃ and a machine speed of 22 m / min. After completing the subsequent steps, the seaweed yarn fabric is obtained. Example 4

[0034] This embodiment uses the same steps as Embodiment 1, but employs different production conditions or parameters to produce the finished seaweed yarn fabric. Specifically, the differences are as follows: In step A), seaweed Obviously, the fiber in the above embodiments of the present invention is 1 part, and the total of 9 parts are cotton, Modal, Tencel, silk, wool, nylon and polyester; wherein in the carding stage, the opening machine beater speed is 380 r / min, the fan speed is 670 r / min, the carding machine cylinder speed is 230 r / min, and the licker-in speed is 500 r / min for carding operation, and the humidity of the spinning workshop is maintained at 63% during the operation; B) During the fabric weaving process, the ambient temperature is maintained at 23℃, the relative humidity is maintained at 93%, and the weaving machine is used at a speed of 12r / min. C) Fabric pre-forming is carried out at a temperature of 185℃ and a machine speed of 21 m / min. After completing the subsequent steps, the seaweed yarn fabric is obtained.

[0035] Comparative Example 1 This embodiment uses the same steps as Embodiment 1, but employs different production conditions or parameters to produce the finished seaweed yarn fabric. Specifically, the differences are as follows: In section B), during the fabric weaving process, the ambient temperature is maintained at 30℃, the relative humidity is maintained at 60%, and the weaving machine is operated at a speed of 20 r / min. C) Fabric pre-forming is carried out at a temperature of 150℃ and a machine speed of 25 m / min. After completing the subsequent steps, the seaweed yarn fabric is obtained.

[0036] Comparative Example 2 This embodiment uses the same steps as Embodiment 1, but employs different production conditions or parameters to produce the finished seaweed yarn fabric. Specifically, the differences are as follows: In section C), the pre-forming of the fabric is carried out at a temperature of 150℃ and a machine speed of 25 meters per minute. After completing the subsequent steps, the seaweed yarn fabric is obtained.

[0037] Comparative Example 3 This embodiment uses the same steps as Embodiment 1, but employs different production conditions or parameters to produce the finished seaweed yarn fabric. Specifically, the differences are as follows: In the carding stage of the blended yarn, the carding machine is used with a carding speed of 500 r / min, a fan speed of 500 r / min, a carding machine cylinder speed of 330 r / min, and a licker-in speed of 600 r / min, and then blended into a 60-count blended seaweed yarn. After completing the subsequent steps, the seaweed yarn fabric is obtained.

[0038] Comparative Example 4 This embodiment uses the same steps as Embodiment 2, but employs different dyeing conditions to produce colored seaweed yarn fabric. Specifically, the differences are as follows: This comparative example uses common dyeing methods and procedures, and employs common fabric dyeing methods for the dyeing operation; The finished product is a colored seaweed yarn fabric.

[0039] Experimental example: The seaweed fiber fabrics obtained in Examples 1-4 and Comparative Examples 1-4 were subjected to the following tests: 1) Detection of seaweed fiber content in finished seaweed yarn fabric The methods used for testing seaweed fiber content are as follows: FZ / T 01057.2-2007, FZ / T 01057.3-2007, FZ / T01057.4-2007, FZ / T 01101-2008, GB / T 2910.2-2009, and GB / T 38015-2019. Alternatively, the loss test method can be used: calculate the difference between the theoretical and measured values ​​of seaweed fiber content. Table 1 Seaweed fiber content (%) 32.2 30.5 14.7 6.8 29.8 31.5 28.9 26.7 Seaweed fiber loss (%) 1.8 3.5 2.3 1.7 4.2 2.5 5.1 7.3 As shown in Table 1 above, Example 1 is the optimal example. During the research and development process, by combining the carding stage with subsequent weaving steps under specific conditions, a 60-count high-count seaweed fiber fabric with minimal seaweed loss can be obtained. Examples 3 and 4 show that although 60-count high-count seaweed fiber can still be woven in blended fabrics with reduced seaweed fiber raw materials, the seaweed fiber loss actually increases. This indicates that parameter adjustments during carding, weaving, and pre-setting processes play a crucial role in controlling seaweed fiber loss. Comparing Example 2 and Comparative Example 4, it can be seen that the dyeing steps in this invention can control the seaweed fiber loss in the 60-count high-count seaweed fiber fabric to a minimum. A relatively ideal level, while common dyeing methods significantly increase the loss of seaweed fibers after dyeing. From the comparison of Examples 1, 3, 4 and Comparative Examples 1, 2, 3, it can be seen that the high-count seaweed yarn fiber fabric of the present invention is not caused by a single change in a certain step or parameter. In Comparative Example 4, even if only the temperature, humidity and equipment speed parameters in the weaving step are changed, the final seaweed loss is still higher than that of Examples 1-3. The carding parameters of the 40-count seaweed yarn fabric produced by Comparative Example 3 under normal conditions are directly used in this application and the seaweed fiber loss is also significantly increased. As shown in Table 1, the preparation method of the present invention can increase the seaweed fiber retention in 60-count seaweed fiber fabric.

[0040] 2) Antibacterial performance testing Test basis and method: FZ / T 73023-2006 Antibacterial Knitted Fabrics - Test for antibacterial properties.

[0041] Table 2

[0042] 3) The seaweed yarn fabrics obtained in Examples 1-4 and Comparative Examples 1-4 were subjected to the following tests as shown in Table 3: (Green fabric 150×180cm) Anti-mite performance test Testing basis and methods: GB / T 24253-2009 "Evaluation of mite-proof performance of textiles" Table 3

[0043] The experimental examples show that the content of seaweed fiber in the fabric is directly related to its antibacterial and anti-mite properties. However, comparing Example 3 and Comparative Example 3, Example 3 used 2 parts seaweed fiber, while Comparative Example 3 used the same 4 parts seaweed fiber as Example 1, resulting in a higher seaweed content. Although the antibacterial performance of Example 3 did not exceed that of Comparative Example 3, their performance parameters were very close. Therefore, for high-count seaweed yarn fabrics, specific carding parameters not only affect the seaweed fiber content but also the fabric's antibacterial properties. Generally, seaweed fiber... The antibacterial properties of a fabric are generally related to its seaweed fiber content; the more seaweed fiber, the better the antibacterial properties. However, in the preparation and experimentation of high-count seaweed yarn fabrics, this invention found that suitable carding operations and the environment or operating parameters for weaving and setting also have a significant impact on the antibacterial properties of the final fabric. On the other hand, as shown in Table 3, even with an increased count, the seaweed fiber fabric prepared using this invention does not affect its anti-mite properties. Therefore, it can be seen that this invention can control the loss of seaweed fibers during the preparation of high-count seaweed fiber fabrics while maintaining the fabric's antibacterial and anti-mite functions.

[0044] 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.
