Description

Composite structure yarn with high-efficiency energy-storage light-emitting and light-reflecting functions
Technical Field
The invention belongs to the field of special function yarns, and relates to a composite structure yarn with high-efficiency energy-storage light-emitting and light-reflecting functions.
Background
Since the emergence of reflective film technology, reflective materials are widely used as a safety protection product in various industries such as highways, railways, harbors, fire fighting, airports, license plates and the like. The reflective material can generate strong reflective effect under the irradiation of a certain light source, and provides the most effective and reliable safety guarantee for pedestrians or night operators in darkness. With the rapid development of the reflective material, the application range of the reflective material is gradually expanded, and the reflective silk is used in the fields of decoration, construction, safety, clothing and the like at present, and plays a role in decoration and warning. Especially at night, the light reflecting effect can attract the attention of the vehicle driver, the safety performance of the night trip is improved, and the beautifying effect is achieved.
According to the structure of the reflective unit of the reflective film, the reflective film is divided into two categories: glass bead type reflective films and microprism type reflective films. The microprism reflecting film is divided into a truncated-angle prism reflecting film with good long-distance retroreflection capacity, a truncated-angle prism reflecting film with good short-distance large-angle retroreflection capacity and a full-prism reflecting film which meets the requirements of all aspects according to the form and technical characteristics of the prism.
The glass bead type reflective film mainly has two types, one type is a lens embedded reflective film, and the glass bead type reflective film is customarily called an engineering grade reflective film; one is the sealed capsule type, commonly referred to as high strength retroreflective sheeting.

However, the reflective film can only have a reflective effect under the irradiation of lamplight at night, plays a role in warning, and cannot self-illuminate under the condition of no lamplight.
The luminous fiber is a raw material in the textile industry. The luminous material of the luminous fiber is divided into a self-luminous type and a light-storing type, the basic component of the self-luminous type luminous material is a radioactive material, energy does not need to be absorbed from the outside, and the luminous fiber can continuously emit light no matter at night or in the daytime. However, since the radioactive substance is contained, the use is greatly restricted, and disposal after disposal is also a problem. The light-storing luminous material does not contain radioactive substances and has no limitation in use, but the luminous material can emit light only by absorbing external light energy and can ensure that the light can emit light all the time by storing enough light energy. The luminous fabric is made of luminous materials by a coating method, the fabric has poor hand feeling, wearability, washing resistance and luminous effect, and the pollution to the environment is serious in the production and use processes.
At present, the relevant patents on night optical fibers and reflective filaments are as follows:
chinese invention patent ZL201610577112.2 provides a preparation method of blue light noctilucent fiber, a preparation method of noctilucent fiber capable of emitting red light in dark; chinese patent (ZL201510039602.2) discloses a preparation method of luminous fiber capable of emitting red light in dark places. The Chinese invention patent (application publication No. CN106978641A) provides a rare earth noctilucent fiber, a manufacturing method thereof and a textile fabric based on the noctilucent fiber; the Chinese invention patent (application publication No. CN110055608A) provides a preparation method of a high-strength noctilucent fiber.
The utility model discloses a chinese utility model patent (grant publication number CN208293165U), the utility model discloses a night light reflection of light silk. As shown in figure 1, the noctilucent reflective yarn is formed by mutually winding noctilucent yarns and reflective yarns, the noctilucent yarns are novel functional environment-friendly materials formed by mixing noctilucent powder and polyester high polymer materials, and the reflective yarns are formed by coating a glass bead layer on the surface of polyester filaments.
In addition, the chinese utility model patent (publication No. CN205775047U) discloses a dual-purpose soft silk thread for light emitting and light reflecting, as shown in fig. 2, the dual-purpose soft silk thread for light emitting and light reflecting comprises a plurality of light emitting yarns made of PET material and light reflecting yarns made of nylon FDY material, and the light emitting yarns are coated on the surface of the light reflecting yarns.
The luminous reflecting silk threads are formed by interweaving the reflecting silk threads and the luminous silk threads and are not integrally formed.
The Chinese invention patent (application publication No. CN105242338A) discloses a reflective luminous filament and a preparation method thereof, the structure of which is shown in figure 3, the reflective luminous filament comprises a PET film, a light curing agent layer is coated on the PET film, glass beads are uniformly scattered on the light curing agent layer, a focus resin layer is arranged between an embedded surface of the glass beads and the light curing agent layer, wherein the light curing agent layer comprises polyester glue, a diluent, an adhesive, a curing agent and a fluorescent luminous agent. Meanwhile, the light-emitting and light-reflecting dual-effect is achieved. However, the reflective noctilucent yarn is still a reflective film made of a film structure, is not a silk thread in the true sense, is still reflective on a single surface, and has great limitation in application to textile fabrics.
