Description
Technical Field
The invention relates to the technical field of intelligent textiles, in particular to a production process of a large-breadth light-emitting fabric with customizable patterns.
Background
The luminous fabric is based on the use of an optical fiber, and the optical fiber can be combined with all natural fibers or chemical fibers to be woven into fabrics with various textures, and can meet the finishing requirement of a weaving process. The luminous fabric has wide application, can supply power to the electrostatic luminous fabric by using the storage battery, and is used for household textiles such as curtains, tablecloths and the like; it is also possible to use a small battery for clothing (e.g., show clothing) that is wired for eight hours. In addition to this there are many small uses, such as making the festival atmosphere of a nightclub; liners for various products, such as handbag liners, to facilitate night key finding; and some safety aspects.
The principle of the light-emitting fabric is that optical fibers are damaged or bent, so that the optical fibers in the optical fibers escape outwards to show a light-emitting effect. Methods of damaging the optical fiber include moving the cleave with a laser cutter, but have several problems: a. due to the limitation of the moving range of the cutting pattern, the size of the flower type pattern is limited; b. the laser generator of the laser cutting machine mainly cuts off the fabric, so that the cutting depth precision of the fabric is not high, and the fabric cannot be precisely engraved according to the light intensity requirement; c. different from the conventional fabric cutting, the pattern carving is not only lines or points, but also has long operation stroke and low integral working efficiency.
The method for destroying optical fiber also includes carving with laser head, which overcomes the defects of low efficiency and poor precision of laser cutter, but the laser of laser carving machine is of carbon dioxide and CO2The laser device can attenuate the light path along with the increase of the distance between the laser beam and the working surface, the laser engraving power is originally smaller, the light spot is seriously increased, and the good engraving effect can not be ensured despite the assistance of the light attenuation compensation technology. Therefore, in the same pattern, the laser intensities of the left, the middle and the right have great difference, so that the engraving depths are different, the engraving depth and the size of the optical fiber cannot be controlled well, and the final light-emitting uncertainty of the optical fiber fabric is caused, so that the width of the optical fiber fabric for operation has great limitation, and the large-breadth pattern operation cannot be carried out.
In the prior art, the optical fiber is damaged by a chemical dissolution method, wherein the chemical dissolution method is to adhere a chemical solvent capable of dissolving a substance of a skin layer of the optical fiber to the surface layer of the optical fiber, dissolve the skin layer and not damage a core layer, thereby achieving the principle of optical fiber luminescence. The method needs to accurately control the amount of the solvent and the diffusion area dissolved on the surface of the optical fiber, so that the viscosity and the attachment time of the solvent need to be strictly controlled, and the mass production cannot be completed for the advancement and technical stability of the current equipment.
In the prior art, the optical fiber is made to emit light by a weaving process. Through the weaving process, the interweaving of the warp and weft yarns can cause the undulation and bending of the yarns, and the light emitting of the optical fibers is controlled by controlling the bending degree of the optical fibers in the weaving process. The technical realization has great limitation, if the bending angle is insufficient, the light in the optical fiber cannot escape, and if the angle is too large, the optical fiber is easy to break, thereby destroying the light emitting continuity of the whole optical fiber.
Moreover, compared with other conventional fabric fibers, although the fibers are subjected to technical iteration, the fibers are still thick, the hardness is high, and the spinnability is poor.
In summary, the existing luminescent fabric has the following problems: the limitation of the size of the pattern is large, the carving depth is difficult to control accurately when a laser carving method is adopted, the working efficiency is low, the fabric width has large limitation, the batch production of the fabric cannot be realized by adopting a chemical dissolution method, the limitation is large when the fabric has a light-emitting function and is difficult to control by adopting a weaving process, the optical fibers are thick and hard relatively, the preventability is poor, the woven fabric has poor hand feeling and the processing difficulty is high.
