Description

Technical Field

[0001] The present application relates to the field of textile technology, and more specifically, to a method for weaving a novel fabric blended or interwoven with paper yarn fibers. Background Art

[0002] With the enhancement of global environmental awareness, the dual carbon goals have become a guide to action for many industries, especially in the textile industry. It is particularly important to seek low-carbon and environmentally friendly raw materials and manufacturing processes. Traditional textile materials often find it difficult to balance performance and ecological sustainability. Paper yarn, as a naturally derived and 100% biodegradable fiber, has shown great potential. Fabrics woven from paper yarn can be used in the home textile field and used to make bedding, which is more green and environmentally friendly.

[0003] However, compared with traditional textile fibers such as cotton fiber and polyester fiber, paper yarn is weaker and is easily broken or damaged when subjected to greater tension or friction. In addition, paper yarn will swell after absorbing water. After long-term use, the structure of paper yarn will be damaged, resulting in reduced strength, insufficient wear resistance, reduced comfort and shortened service life of the fabric woven from paper yarn. Summary of the invention

[0004] In order to improve the durability of fabrics, the present application provides a method for weaving a new type of fabric by blending or interweaving paper yarn fibers.

[0005] A method for weaving a novel fabric blended or interwoven with paper yarn fibers comprises the following steps: Yarn preparation: After mixing paper yarn with other fibers, composite yarn is prepared by blending, core-spun yarn or embedded spinning, wherein the other fibers are selected from one of lyocell fiber and cotton fiber, or lyocell fiber and ramie; Fabric weaving: The composite yarn is woven into fabric in a plain or satin weave; Post-treatment: soak the woven fabric in antibacterial treatment liquid for 50-70 minutes, rinse 3-5 times, and dry at 55-60℃.

[0006] By adopting the above technical scheme, the paper yarn is obtained by winding and compressing paper fibers, and has high strength and wear resistance. At the same time, it is a natural fiber with good decomposability and good environmental protection. The paper yarn is blended and compounded with other fibers by core-spun yarn or embedded spinning. Lyocell fiber is a semi-synthetic fiber made from natural plant fiber as raw material, and has good comfort, high strength, good moisture absorption and air permeability. Ramie and cotton fiber are natural fibers with high strength and good moisture absorption and air permeability. After blending and compounding, the composite yarn can be provided with relatively good strength, wear resistance, moisture absorption and air permeability, which effectively improves the performance of the composite yarn, thereby improving the durability of the composite yarn. The fabric formed by weaving the composite yarn has good wear resistance. After post-treatment, the fabric has long-lasting antibacterial properties, which further improves the durability of the fabric.

[0007] Preferably, when the other fibers are lyocell fibers or cotton fibers, the mass ratio of the paper yarn to the other fibers is (1.95-2.12):(7.98-8.12).

[0008] By adopting the above technical solution, the mass ratio of paper yarn to lyocell fiber or cotton fiber is controlled, so that the composite yarn has good wear resistance and good antibacterial performance.

[0009] Preferably, when the other fibers are lyocell fiber and ramie, the mass percentage of paper yarn in the composite yarn is 15-43%, the mass percentage of lyocell fiber in the composite yarn is 35-73%, and the mass percentage of ramie in the composite yarn is 8-20%.

[0013] Preferably, the composite antibacterial substance is graphene oxide / chitosan composite microspheres.

[0014] By adopting the above technical scheme, graphene oxide can cause bacteria to lyse and die through oxidation, destruction of phospholipids and other methods, and has an antibacterial effect. The surface of chitosan has more amino groups, which can interact with negatively charged substances on the surface of microbial cell membranes, destroying the permeability of cell membranes and killing bacteria. The composite microspheres formed by the two have good adsorption properties, which can not only adhere to the surface of the fabric to achieve a long-term antibacterial effect, but also adsorb bacterial microorganisms and inhibit their growth.

[0015] Preferably, the method for preparing the graphene oxide / chitosan composite microspheres comprises the following steps: ultrasonically dispersing graphene oxide in water, adding an acetic acid solution of chitosan, ultrasonically and evenly mixing, then dropwise adding to liquid paraffin containing an emulsifier, stirring for 1-1.2 hours, adding a cross-linking agent, stirring and reacting at 45-50° C. for 3-4 hours, adding a sodium hydroxide solution, precipitating, centrifuging, separating, and drying to obtain graphene oxide / chitosan composite microspheres.

[0016] By adopting the above technical solution, graphene oxide is dispersed in chitosan, the two are mixed, and composite microspheres are formed by the reverse emulsion cross-linking method. By controlling the reaction conditions, microspheres with regular shapes can be obtained, and the ball formation rate is good and stable.

[0017] Preferably, the graphene oxide / chitosan composite microspheres are treated as follows: adding the graphene oxide / chitosan composite microspheres to phosphate buffer, ultrasonicating for 25-30 minutes, adding lysozyme, magnetically stirring at 3-5°C for 1-1.2 hours, centrifuging, washing with buffer, and freeze-drying to obtain graphene oxide / chitosan composite microspheres loaded with lysozyme.

[0018] By adopting the above technical scheme, the graphene oxide / chitosan composite microspheres have good adsorption properties, and lysozyme can be loaded on the surface of the graphene oxide / chitosan composite microspheres by electrostatic adsorption and the like, thereby further improving the antibacterial properties of the graphene oxide / chitosan composite microspheres.

[0019] Preferably, the mass ratio of the lysozyme to the graphene oxide / chitosan composite microspheres is (2.8-3.2):(1.8-2.1).

[0020] By adopting the above technical solution, the mass ratio of lysozyme to graphene oxide / chitosan composite microspheres is controlled, so that the composite microspheres can load more lysozyme, while reducing unnecessary consumption of lysozyme.

[0021] In summary, this application has the following beneficial effects: 1. Since the present application blends paper yarn with other fibers by core-spun yarn or embedded spinning, Lyocell fiber is a semi-synthetic fiber made from natural plant fiber, has good comfort, high strength, good moisture absorption and air permeability, and ramie and cotton fibers are natural fibers with high strength and good moisture absorption and air permeability. After blending and compounding, they can provide the composite yarn with relatively good strength, wear resistance, moisture absorption and air permeability, effectively improving the performance of the composite yarn, thereby improving the durability of the composite yarn. The fabric formed by weaving the composite yarn has good wear resistance. After post-treatment, the fabric has long-lasting antibacterial properties, which further improves the durability of the fabric.

[0022] 2. In the present application, an antibacterial treatment liquid is used to post-treat the fabric. The antibacterial treatment liquid contains a composite antibacterial substance. The fabric is treated with the antibacterial treatment liquid containing the composite antibacterial substance, and the composite antibacterial substance adheres to the surface of the fabric, which can effectively improve the antibacterial property of the fabric.

[0023] 3. Graphene oxide is used in this application. Graphene oxide can cause bacteria to lyse and die by oxidation, destruction of phospholipids and other methods, and has an antibacterial effect. The surface of chitosan has a large number of amino groups, which can interact with negatively charged substances on the surface of microbial cell membranes, destroy the permeability of cell membranes, and thus kill bacteria. The composite microspheres formed by the two have good adsorption properties, which can not only adhere to the surface of the fabric to achieve a long-term antibacterial effect, but also can adsorb bacterial microorganisms and inhibit their growth.

[0059] Comparative Example 1 The difference between Comparative Example 1 and Example 1 is that in Comparative Example 1, the fabric is not post-treated. Test methods

[0060] The fabrics prepared in Examples 1-22 and Comparative Example 1 were tested for abrasion resistance, color fastness and antibacterial rate. The testing standard referred to GB / T 22796-2021 "Bedding", and the antibacterial rate test bacteria were golden staphylococcus. The results were recorded in Table 1. Each fabric was machine washed 50 times using the standard program of the same brand washing machine, and the antibacterial rate of the fabric was tested again, and its long-term antibacterial performance was recorded in Table 1.

[0061] Table 1 Fabric performance test results project Wear resistance / grade Color fastness / grade Antibacterial rate / % Long-term antibacterial effect / % Example 1 4 3 99.62 97.64 Example 2 4 3 99.65 97.92 Example 3 4 3 99.70 97.57 Example 4 4 3 99.53 97.75 Example 5 4 3 99.68 97.68 Example 6 4 3 99.59 97.51 Example 7 4 3 99.71 97.46 Example 8 4 3 99.66 97.59 Example 9 4 3 99.26 96.56 Example 10 4 3 99.31 96.42 Embodiment 11 4 3 99.98 98.68 Example 12 4 3 99.97 98.71 Example 13 4 3 99.72 97.68 Embodiment 14 4 3 99.68 97.81 Embodiment 15 4 3 99.30 95.16 Example 16 4 3 99.27 96.05 Embodiment 17 3 2 99.58 97.51 Embodiment 18 3 2 99.61 97.34 Embodiment 19 3 2 99.52 97.29 Embodiment 20 3 2 99.57 97.56 Embodiment 21 3 2 99.54 97.24 Embodiment 22 3 2 99.62 97.16 Comparative Example 1 4 3 99.02 94.98 According to Table 1 and Examples 1-8, it can be seen that the fabric prepared in the present application has good wear resistance, color fastness and antibacterial effect. At the same time, after long-term use, the antibacterial rate of the fabric decreases slightly, and it has long-lasting antibacterial performance. Paper yarn can be made by recycling pulp, Lyocell fiber is a semi-synthetic fiber made from natural plant fiber as raw material, ramie and cotton fiber are natural fibers, and the fabric prepared in the present application is synthesized from natural fibers or natural plants, can be degraded, and is environmentally friendly. At the same time, Lyocell fiber, ramie and cotton have good comfort, high strength, and good moisture absorption and air permeability, so that the composite yarn has good strength, wear resistance and moisture absorption and air permeability, and thus the fabric has good strength and wear resistance. After the fabric is post-treated with an antibacterial treatment liquid, the fabric has good antibacterial properties. After long-term use, its performance has not decreased, and good fabric performance is maintained.

[0062] Compared with Example 1, the fabric prepared in Comparative Example 1 has poor antibacterial performance. Comparative Example 1 is not post-treated, and the antibacterial treatment liquid contains a composite antibacterial substance, which is a graphene oxide / chitosan composite microsphere. The surface of graphene oxide contains more active groups, which can cause cell lysis and death in various ways such as oxidation and destruction of phospholipids. The surface of chitosan contains more amino groups, which can interact with negatively charged substances on the surface of cell membranes of microorganisms and bacteria, destroy the permeability of cell membranes, and thus cause cell death. Graphene oxide and chitosan are compounded to form microspheres. The composite microspheres have good adsorption properties, which can enable the composite microspheres to adhere to the surface of the fabric to achieve a long-lasting antibacterial effect, and can also adsorb bacteria and microorganisms to inhibit their growth and reproduction.

[0063] Compared with Example 1, the antibacterial effect and long-term antibacterial performance of Example 9-10 are reduced. The mass ratio of graphene oxide to chitosan was changed during the preparation of the graphene oxide / chitosan composite microspheres used in Examples 9-10, indicating that the mass ratio of graphene oxide to chitosan will affect the antibacterial effect of the graphene oxide / chitosan composite microspheres. The amount of graphene oxide added is reduced, the adsorption performance of the graphene oxide / chitosan composite microspheres is reduced, the adsorption to the fabric is poor, and the adsorption to bacterial microorganisms is poor, thereby reducing the antibacterial performance of the fabric. The amount of graphene oxide added is increased, agglomeration is prone to occur, and the dispersion is poor, thereby affecting the effect of the graphene oxide / chitosan composite microspheres.

[0064] Compared with Example 1, the antibacterial effect and long-term antibacterial performance of Example 11-12 are improved. The graphene oxide / chitosan composite microspheres used in Example 11-12 are treated so that lysozyme is loaded and fixed on the surface of the composite microspheres. Lysozyme has an inactivation effect on bacterial microorganisms. Lysozyme is fixed on the surface of the graphene oxide / chitosan composite microspheres, which makes the composite antibacterial substance have better inhibition and inactivation effects on bacterial microorganisms, thereby improving the antibacterial effect and long-term antibacterial performance of the fabric.

[0065] Compared with Example 11, the antibacterial effect and long-term antibacterial performance of Example 13 are similar to those of Example 11, and the antibacterial effect and long-term antibacterial performance of Example 14 are lower than those of Example 11. The mass ratio of lysozyme to graphene oxide / chitosan composite microspheres is changed in Examples 13-14. The mass ratio of lysozyme to graphene oxide / chitosan composite microspheres is increased in Example 13, and the antibacterial effect does not change significantly, indicating that the load fixed amount of lysozyme in Example 11 tends to be saturated, while Example 14 reduces the load fixed amount of lysozyme, thereby reducing the antibacterial effect of the fabric.

[0066] Compared with Example 1, the antibacterial effect and long-term antibacterial performance of Example 15 are reduced compared with Example 1, and the antibacterial effect and long-term antibacterial performance of Example 16 are similar to those of Example 1. Examples 15-16 change the content of the composite antibacterial substance in the antibacterial treatment liquid. The content of the composite antibacterial substance in Example 15 is reduced, so that the content of the graphene oxide / chitosan composite microspheres attached to the fabric is reduced, thereby reducing its antibacterial performance. The content of the composite antibacterial substance in Example 16 is increased, and the antibacterial performance of the fabric changes little, indicating that more graphene oxide / chitosan composite microspheres are not attached to the fabric during post-treatment, or fall off during rinsing.

[0067] Compared with Example 1, the wear resistance and color fastness of Examples 17-18 are reduced, and the mass ratio of paper yarn to lyocell fiber is changed in Examples 17-18. Compared with Example 3, the wear resistance and color fastness of Examples 19-20 are reduced, and the contents of paper yarn, lyocell fiber and ramie in the composite yarn are changed in Examples 19-20. Compared with Example 5, the wear resistance and color fastness of Examples 21-22 are reduced, and the mass of paper yarn and cotton fiber is changed in Examples 21-22, indicating that the composite yarn is prepared by compounding paper yarn with other fibers, and the mass ratio between paper yarn and other fibers has a better quality ratio, so that the prepared composite yarn has good wear resistance and color fastness, thereby extending the service life of the fabric and having good durability.

[0068] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
