Description

Technical Field

[0001] The utility model relates to the technical field of flax yarns, in particular to a highly wrinkle-resistant flax yarn. Background Art

[0002] Flax is a natural fiber with great toughness. Its fabric has the advantages of good moisture absorption and release, being straight and refreshing, and not sticking to the body. However, due to its high crystallinity, high bending stiffness, high tensile modulus, and poor elasticity, flax fiber is difficult to dye, has poor elasticity, and is easy to wrinkle. Other fabrics will slowly return to their original shape after deformation, but flax fabric cannot do this. Once deformed, it can only wrinkle, and its dimensional stability is poor, which is also caused by its easy wrinkling. Therefore, it is difficult to measure the size and there will be deviations. The defects of flax fabric can be compensated by blending flax fiber with other fibers with complementary properties, wrapping, etc. Therefore, the utility model provides a highly wrinkle-resistant flax yarn.

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] Combination Figure 1 This embodiment is described in detail. A highly wrinkle-resistant linen yarn comprises: a yarn body, the yarn body comprising a core yarn, a coating layer and a wrapping yarn; the coating layer is wrapped around the outside of the core yarn, and the wrapping yarn is spirally wound around the outside of the coating layer; the core yarn is an elastic composite yarn; the wrapping yarn is twisted from linen fiber yarn and colored polyester filament. The elastic composite yarn as the core yarn can give the yarn body good stretch recovery performance, and the fabric woven from it will slowly return to its original shape after stretching and deformation, which has a good anti-wrinkle effect.

[0018] Further, the elastic composite yarn is formed by twisting PTT fiber filaments and spandex filaments. PTT fiber is a polyester fiber with reorganized molecular structure, which has good resilience and bulkiness, and its anti-fouling, anti-wear and antistatic properties are also good. Spandex is a synthetic fiber with high elongation at break, low modulus and high elastic recovery rate, also known as elastic fiber. The reason why spandex fiber has such high elasticity is that its polymer chain is composed of a low-melting point, amorphous "soft" segment as the matrix and a high-melting point, crystalline "hard" segment embedded therein. The flexible segment molecular chains form a certain network structure with certain cross-linking. Due to the small interaction force between the molecular chains, they can be freely stretched and retracted, resulting in large elongation performance. The rigid segment molecular chain has a relatively large binding force, and the molecular chain will not be extended indefinitely, resulting in high resilience. This fiber has both rubber properties and fiber properties. When used for core yarn, it can make the yarn body obtain good elasticity, thereby achieving a good wrinkle-resistant effect for the fabric.

[0019] Furthermore, the coating layer is a flame retardant layer, and the flame retardant layer is a flame retardant polyester fiber layer. The flame retardant polyester fiber is prepared by adding a non-halogen phosphorus-based reactive flame retardant and an inorganic polymer flame retardant during the polymerization process and then melt spinning. The fabric woven from the yarn body with the flame retardant layer can reduce the flammability of the fabric during flame combustion, slow down the speed of flame spread, and prevent large-scale combustion. After leaving the flame, it can quickly extinguish itself and no longer burn, thereby achieving the purpose of flame retardancy and having a permanent flame retardant effect.

[0020] Further, the fineness of the colored polyester filament is 167dtex / 36f, and the color is any one of black, navy blue or royal blue. Specifically, in this embodiment, the colored polyester filament is navy blue. The wrapped yarn twisted by the flax fiber yarn and the colored polyester filament has a linen color appearance, the flax fiber yarn is light in color at the thick section and dark in color at the detail, and the wrapped yarn has a weak color effect along the length direction.

[0021] Embodiment 2

[0022] Combination Figure 2 This embodiment is described in detail. The difference from the first embodiment is that the elastic composite yarn has a spandex filament as the core and is wrapped with a polyolefin elastic fiber. The polyolefin elastic fiber is made by melt spinning a polyolefin thermoplastic elastomer. It has good elasticity and is an elastic fiber that can provide long-term elasticity and recovery. It can withstand temperatures up to 220°C and has the characteristics of being resistant to strong acids, strong alkalis, and strong oxidants. At the same time, it produces almost no pollution during the production process and is easy to recycle.

[0023] Embodiment 3

[0024] Combination Figure 3This embodiment is described in detail. The difference from the first embodiment is that an anti-mosquito finishing agent is also attached to the outer side of the wrapped yarn. Specifically, the anti-mosquito finishing agent is an environmentally friendly anti-mosquito finishing agent AI-C, the main component of which is a nano-scale microcapsule of an insecticide polyester compound. It forms an insect repellent film on the surface of the yarn through a fixing agent, and has a high efficiency and rapid knockdown and killing effect and a good repelling effect on mosquitoes, flies, fleas, lice, moths, etc.

[0025] 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.
