Description

Technical Field

[0001] The utility model relates to the technical field of aromatic textile fabrics, in particular to a synthetic fiber composite fabric with a long-lasting fragrance-releasing function. Background Art

[0002] Traditional scented fabrics generally emit natural fragrance, which is refreshing and helps to improve comfort, and are therefore popular among people. However, due to the simple process and single structure of traditional scented fabrics, the fragrance of the fabrics dissipates quickly and lasts for a short time. In addition, the fragrance release process is generally transient, which makes the attractive scented fabrics with application advantages quickly become ordinary fabrics and lose their value.

[0003] Therefore, how to improve the fragrance retention of scented fabrics has become the key to research and application. In the prior art, by setting up scent microcapsules, the purpose of slowing down the release rate of fragrance and prolonging the fragrance retention can be achieved, as described in patent CN208035605U. However, it can be seen that the structure of the scent microcapsules in this patent is relatively simple, and the scent microcapsules are damaged and emit fragrance after being patted during application (no fragrance is released without patting, that is, the fragrance is not released automatically), which has certain operational limitations. As described in patent CN202576763U, a microcapsule fragrance coating is provided on the outer surface of the PVC fabric. It can be seen that both this patent and the above patents set the scent microcapsules on the surface of the fabric. Under long-term use, the scent microcapsules are easily worn and broken, thereby reducing the service life of the scented fabric and losing the fragrance retention of the scented fabric; in addition, the structure and function of the scent microcapsules in these two patents are relatively simple, and the scent microcapsules on the surface are completely exposed to the fragrance core material after being broken, and gradually lose the fragrance release function, so their fragrance release persistence needs to be further optimized and improved.

[0004] To this end, based on the existing technology, the utility model creatively designs a synthetic fiber composite fabric with a long-lasting fragrance release function that combines water-soluble fragrance microcapsules and sustained-release fragrance microcapsules. Through the alternation and mutual complementation of the two, the purpose is to improve the fragrance release efficiency and fragrance release durability of the synthetic fiber composite fabric. Utility Model Content

[0008] The water-soluble aromatic microcapsule is composed of a first aromatic core material and a water-soluble porous shell wrapped around the aromatic core material;

[0009] The slow-release aroma microcapsule is composed of a second aroma core material and a porous slow-release shell wrapped around the second aroma core material.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 , the utility model provides: Specific embodiment 1

[0024] A synthetic fiber composite fabric with a long-lasting fragrance release function is woven from warp yarn 1 and weft yarn 2. The warp yarn 1 and weft yarn 2 are respectively formed by winding a plurality of single yarns with each other. Gaps are formed between the wound yarns for filling microcapsules, thereby wrapping the microcapsules in the warp yarn 1 and the weft yarn 2. The gaps formed in the wound warp yarn 1 are filled with 20% of water-soluble fragrance microcapsules 3, and the gaps formed in the wound weft yarn 2 are filled with 30% of slow-release fragrance microcapsules 4.

[0025] In this embodiment 1, the water-soluble aromatic microcapsule 3 is spherical with an average particle size of 5 μm. The water-soluble aromatic microcapsule 3 is composed of a first aromatic core material 301 (solid aromatic finishing agent) and a water-soluble porous shell 302 (polyvinyl alcohol-based porous material) wrapped around the outside of the aromatic core material, and the thickness of the water-soluble porous shell in the water-soluble aromatic microcapsule is 0.5 μm.

[0026] In this embodiment 1, the sustained-release fragrance microcapsule 4 is spherical with an average particle size of 15 μm (three times the average particle size of the water-soluble fragrance microcapsule). The sustained-release fragrance microcapsule 4 is composed of a second fragrance core material 401 (solid fragrance finishing agent) and a porous sustained-release shell 402 (polyurethane shell) wrapped around the outside of the second fragrance core material 401. The thickness of the porous sustained-release shell in the sustained-release fragrance microcapsule is 2 μm, the pore size of the porous sustained-release shell is 0.3 μm, and the porosity is 62%. Specific embodiment 2

[0028] The synthetic fiber composite fabric with long-lasting fragrance release function in this embodiment 2 has the same structure as that in embodiment 1, except that: the filling rate of the water-soluble aromatic microcapsules 3 in the warp yarn 1 is 50%, and the filling rate of the slow-release aromatic microcapsules 4 in the weft yarn 2 is 70%; the water-soluble aromatic microcapsules 3 are ellipsoids with an average particle size of 10 μm, and the thickness of the water-soluble porous shell in the water-soluble aromatic microcapsules is 1.2 μm; the slow-release aromatic microcapsules 4 are ellipsoids with an average particle size of 50 μm (5 times the average particle size of the water-soluble aromatic microcapsules), and the thickness of the porous slow-release shell in the slow-release aromatic microcapsules is 3 μm, the pore size of the porous slow-release shell is 0.8 μm, and the porosity is 83%. Specific embodiment 3

[0030] The synthetic fiber composite fabric with long-lasting fragrance release function in this embodiment 3 has the same structure as that in embodiment 1, except that: the filling rate of the water-soluble aromatic microcapsules 3 in the warp yarn 1 is 30%, and the filling rate of the slow-release aromatic microcapsules 4 in the weft yarn 2 is 60%; the water-soluble aromatic microcapsules 3 are spherical with an average particle size of 8 μm, and the thickness of the water-soluble porous shell in the water-soluble aromatic microcapsules is 0.9 μm; the slow-release aromatic microcapsules 4 are spherical with an average particle size of 32 μm (4 times the average particle size of the water-soluble aromatic microcapsules), and the thickness of the porous slow-release shell in the slow-release aromatic microcapsules is 2.5 μm, the pore size of the porous slow-release shell is 0.6 μm, and the porosity is 78%.

[0031] When the utility model is in use, the water-soluble aromatic microcapsules filled in the warp yarns will be broken by external force (patting or rubbing) due to their thin water-soluble porous shells, thereby preferentially releasing the aromatic smell; when the water-soluble aromatic microcapsules are not broken, the sustained-release aromatic microcapsules slowly release the fragrance from their porous sustained-release shells, and the two complement each other to improve the aromatic performance of the fabric; the water-soluble porous shell has a water-soluble property, and after washing, the water-soluble porous shell will be dissolved, thereby further completely releasing the aromatic smell; the released aromatic smell will be absorbed by the warp yarns and the weft yarns, and the aromatic smell can be significantly prolonged.

[0032] After repeated washing, the water-soluble fragrance microcapsules gradually exert their fragrance function due to rupture or dissolution. At this time, the sustained-release fragrance microcapsules filled in the weft yarn can further exert the fragrance. Moreover, since the sustained-release fragrance microcapsules are larger in size (larger average particle size and thicker porous sustained-release shell), the release of the fragrance can be further effectively prolonged. Therefore, the sustained-release fragrance microcapsules supplement the release of the fragrance on the basis of the water-soluble fragrance microcapsules, so that the fragrance remains long-lasting and rich.

[0033] It can be seen from the above embodiments of the utility model that the utility model designs water-soluble aromatic microcapsules and sustained-release aromatic microcapsules, and fills them in the warp yarn and weft yarn respectively, which can play a certain protective role and prevent the water-soluble aromatic microcapsules and the sustained-release aromatic microcapsules from falling off, thereby reducing the aromatic performance; the two aromatic microcapsule structures with different functions alternate and complement each other, giving full play to the advantages of the water-soluble aromatic microcapsules' rapid and preferential fragrance release and the sustained-release aromatic microcapsules' long-lasting fragrance release, overcoming the problems of the slow fragrance release of the sustained-release aromatic microcapsules and the thorough and non-persistent fragrance release of the water-soluble aromatic microcapsules, the two complement each other's advantages, play to their strengths and avoid their weaknesses, and significantly improve the fragrance release performance of the synthetic fiber composite fabric.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
