Description

Luminous fabric

The present invention relates to a fabric, and more particularly to a luminescent fabric.

Today's common light-emitting fabrics can be mainly divided into two types: passive reflective type and active light-emitting type. Among them, the passive reflective type of light-emitting fabric uses a reflective material to illuminate light by means of reflection. In application, the intensity of the light is limited by the intensity of the illumination source. When the intensity of the illumination source is weakened, the passive reflection type is illuminated. The reflective effect of the fabric will also decrease. For workers with insufficient light or nighttime hours, the warning effect can be limited and the safety cannot be effectively improved.

In view of the problem that the passive reflective type luminescent fabric has poor illuminating effect and generally low practicality, an active illuminating type luminescent fabric has been developed. The active light-emitting type of light-emitting fabric is usually provided with a light source, and the light generated by the light source achieves the effect of light-emitting display. For example, a light-emitting diode such as a light-emitting diode, a light-emitting strip or a light bulb is mounted by sewing, pasting or weaving, and the light generated by the light-emitting elements is used for safety and warning purposes.

In addition, there are still manufacturers who want to make clothes more beautiful and interesting. By adding its added value, the light-emitting element is combined with the clothes to form a luminous effect on the laundry.

However, the existing illuminating fabric is combined with the illuminating member by the illuminating member, and the woven fabric is composed of fibers and is a staggered woven structure, and the fibers are mainly divided into two structures of a multifilament and a monofilament, and the multifilament is easy to have a plurality of structures. The light is lost due to refraction, resulting in a decrease in light guiding property, and the light source cannot be effectively diffused. If a monofilament structure is used, the structure is relatively fragile and easily destroyed in the process of hot working. Furthermore, the conventional light-emitting fabric has a problem of poor light guiding property, so that the installed light-emitting element can emit light only at a fixed point, or a large number of light-emitting elements need to be used to achieve the desired effect.

Based on the development and application of the above-mentioned luminescent fabric, how to make the light source can effectively diffuse and conduct, and the luminescent fabric with safety, warning, illumination and entertainment properties is the goal of the new research and improvement.

Accordingly, it is an object of the present invention to provide a luminescent fabric that enhances light directivity and increases the range of illumination of the source.

Therefore, the novel luminescent fabric comprises a light transmitting unit, at least one light emitting unit combined with the light transmitting unit, and a power unit electrically connected to the light emitting unit.

The light transmissive unit comprises a plurality of conjugate fibers, each conjugate fiber having a sheath portion and at least one core portion covered by the sheath portion, the light transmissive unit being warp and weft with each other by the composite fibers Weaving to the interaction and forming a network structure, and the nodes of the network structure are sheaths of the composite fibers The parts are fused to each other via heat treatment.

Preferably, the illuminating fabric, wherein the two adjacent composite fibers of the light transmitting unit are arranged at intervals.

Preferably, the luminescent fabric has a sheath portion and a plurality of core portions covered by the sheath portion.

Preferably, the luminescent fabric, wherein the constituent material of the sheath portion is selected from the group consisting of polyethylene terephthalate having a melting point of 100 ° C to 210 ° C, and the constituent material of the core is selected from the group consisting of a melting point of more than 210 ° C. Ethylene terephthalate.

The light transmissive unit 2 is composed of the composite fibers 21 is mesh-like in each other in the warp and weft directions, and any two adjacent composite fibers 21 are arranged at intervals, and the nodes of the mesh structure are sheath portions 211 of the composite fibers 21. They are fused to each other via heat treatment.

Referring to FIG. 3, the light transmissive unit 2 is formed by stacking a plurality of composite fiber filaments 21 ' into a strip shape, wherein each of the composite fiber filaments 21 ' has a shell layer 211 '. and the shell 211 is a "coated core 212 '; and the like and then the long-shaped composite fiber yarn 21' woven warp and weft (Figure 4), after completion of knitting Performing a heat treatment step, the temperature of the heat treatment is between the melting point temperatures of the shell layers 211 ′ , so the shell layers 211 ′ are melted and melted together during heating (as shown in FIG. 5 ), and cooled. The shell layers 211 ' then become the sheath portions 211 of the composite fibers 21, and the cores 212 ' are the core portions 212 of the composite fibers 21. The latitude and longitude interlaced nodes are also combined because the shell layers 211 ' are melted and cooled, so that the light transmissive unit 2 exhibits an overall planar network structure.
