Description

Technical Field

[0001] The utility model relates to the technical field of flax yarns, in particular to an antiseptic and antibacterial flax yarn. Background Art

[0002] Flax fiber is the earliest natural fiber used by humans. It is the only bundled plant fiber among natural fibers. It has a natural spindle-shaped structure and unique pectin-like bevel holes, resulting in excellent moisture absorption, breathability, antiseptic, antibacterial, low static electricity and other properties. Therefore, the yarn spun from it has a wide range of uses. However, the yarn spun from pure flax fiber is rough, has poor elasticity and wrinkle resistance, and does not have flame retardant function. In addition, when flax yarn is used to make home textile fabrics such as curtains and sofa fabrics, the flame retardant problem needs to be considered from a safety perspective. Therefore, it is necessary to develop a flame retardant and antiseptic flax yarn. Utility Model Content

[0011] In the figure: 1-elastic core, 2-first wrapping layer, 3-second wrapping layer, 4-antibacterial yarn, 5-flame retardant yarn. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Combination Figure 1 The present embodiment is described in detail. An antiseptic and antibacterial linen yarn comprises: a yarn body, wherein the yarn body comprises an elastic base core 1, a first wrapping layer 2 and a second wrapping layer 3; the first wrapping layer 2 is spirally wound on the outside of the elastic base core 1; the second wrapping layer 3 is spirally wound on the outside of the first wrapping layer 2; the first wrapping layer 2 is an antibacterial yarn 4; the second wrapping layer 3 is a flame retardant yarn 5; the antibacterial yarn 4 is twisted by flax fiber yarn and antibacterial, mildew-proof and formaldehyde-removing multifunctional viscose fiber yarn.

[0014] Specifically, the antibacterial, mildew-proof and formaldehyde-removing multifunctional viscose fiber is prepared by wet spinning process using wild chrysanthemum extract, coptis chinensis extract and sweet orange essential oil microcapsules of Chinese herbal medicines, and zeolite micropowder suspension, with the mass ratio of wild chrysanthemum, coptis chinensis extract and zeolite micropowder suspension added in an amount of 3.0%, 4.0% and 6.0% of the fiber respectively, and the volume ratio of sweet orange essential oil microcapsules added in an amount of 1.5% of the spinning solution. Among them, coptis chinensis, wild chrysanthemum extract and sweet orange essential oil have good antibacterial and mildew-proof properties. Zeolite micropowder has good adsorption and has a good effect as a substrate for adsorbing formaldehyde functional agents. The yarn made by spinning the antibacterial, mildew-proof and formaldehyde-removing multifunctional viscose fiber has an antibacterial rate of 97.04% against Staphylococcus aureus, and the mildew-proof performance reaches level 0, which can inhibit the corrosion of mildew on the main body of the yarn and extend the service life of the yarn. The formaldehyde removal rate reaches 60.88%. When the formaldehyde adsorption is nearly saturated, after water washing or high temperature (light) treatment, the formaldehyde in the fiber can be dissolved in water or dissipated, and the formaldehyde can be repeatedly absorbed.

[0015] Furthermore, the elastic core 1 is a polyolefin elastic fiber filament. Polyolefin elastic fiber is made by melt spinning and molecular cross-linking process, and melt spinning polymer can be spun into filaments of different specifications by melt spinning. Polyolefin elastic fiber has a similar elastic mechanism to spandex, which depends on its molecular structure of alternating soft and hard segments, and has the characteristics of small modulus, high elongation and low strength, and has excellent resilience; high temperature resistance, can withstand temperatures up to 220°C; has good chemical corrosion resistance, such as strong acid, strong alkali, strong oxidant, etc.; the polyolefin molecules in the fiber can be degraded for use, the fiber does not contain heavy metals, and no harmful substances are emitted during textile processing. The elastic core can make the fabric woven from the yarn body have good elasticity and good wrinkle resistance.

[0016] Furthermore, the flame retardant yarn 4 is a core polyimide fiber yarn and a flame retardant polyester fiber filament twisted together. Polyimide fiber belongs to a high-performance aromatic heterocyclic polymer with a limiting oxygen index of up to 38%. It carbonizes without droplets when exposed to high-temperature open flames, self-extinguishes when away from the fire, is non-toxic, has good mechanical properties and dimensional stability under high and low temperature environments, and has good thermal oxidation resistance, corrosion resistance, and UV resistance. Flame retardant polyester fiber is prepared by melt spinning by adding non-halogen phosphorus-based reactive flame retardants and inorganic polymer flame retardants during the polymerization process. It is a modified polyester fiber with a limiting oxygen index of more than 32%, which can slow down the spread of flames, does not form large-scale combustion, and has a permanent flame retardant effect. When the yarn body is woven into fabrics such as curtains and sofas, if it is accidentally splashed with ash or sparks, the flame retardant yarn 4 can play a flame retardant effect to avoid large-scale combustion.

[0017] Furthermore, an anti-mildew finishing agent is attached to the surface of the flame-retardant polyester fiber filament.

[0018] Furthermore, the anti-mildew finishing agent is a nano zinc finishing agent. Specifically, the formula of the nano finishing agent is: CHP AMB-120A mass concentration 50g / L, CHP AMB-120B mass concentration 20g / L, CHP AMB-120C mass concentration 15g / L, hydrophilic softener TY-168A mass concentration 6g / L. The flame-retardant polyester fiber filament attached with nano zinc finishing agent has good anti-mildew, antibacterial and anti-mite properties; it has good inhibitory effects on three kinds of molds, Aspergillus niger, Chaetomium globosum and Penicillium funiculum, and the anti-mildew grade reaches level 0; the antibacterial rates of Staphylococcus aureus, Candida albicans and Escherichia coli are all above 99%; the anti-mite performance can also reach 65%. This good anti-mildew effect can slow down the corrosion of mold on the main body of the yarn and extend the service life of the main body of the yarn.

[0019] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
