Description

Technical Field

[0001] The invention relates to a method for changing the surface texture of a yarn, and belongs to the technical field of yarn surface treatment. Background Art

[0002] Fabric is one of the materials used to make clothing. The quality of fabric can not only affect the style and characteristics of clothing, but also directly affect the quality of clothing. With the improvement of people's living standards, people's requirements for fabric performance are also constantly increasing. In the production process of conventional fabrics, in order to make the fabric surface have different textures, laser irradiation can be used to form a pattern texture on the fabric surface. This method will damage the surface of the fabric. For example, when preparing denim, lasers are used to burn the yarn on the surface. Since the fabric is woven from yarn, if the texture of the yarn surface is changed, a fabric with a surface texture different from that of conventional fabrics can also be formed. How to change the surface texture of the yarn becomes a problem to be solved. Summary of the invention

[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Combination Figure 1 , Figure 2 and Figure 3 , the present invention is described in detail. The present invention relates to a method for changing the surface texture of a yarn, and a laser processing device is used to process the surface of the yarn. The laser processing device comprises a laser emitting device 1, a first clamping device 8 and a second clamping device 9; the first clamping device 8 and the second clamping device 9 are used to clamp the yarn to be processed so that it is in a straight state; the laser emitting device 1 can intermittently or continuously emit a laser beam 4 to act on the surface of the yarn to form a non-deformed section in a straight state and a deformed section in a fluffy state; the yarn is a heat-melting synthetic fiber deformed yarn. The laser emitting device 1 can emit laser beams 4 of different powers to adapt to yarns of different materials and different finenesses. The specific power of the laser beam is 5-20W. The heat-melting synthetic fiber filament is a multifilament with multiple single filaments. The deformed yarn utilizes the characteristics of thermal deformation of synthetic fibers, and under the action of machinery and heat, the straightened fibers are transformed into curly fiber filaments. Common types of deformed yarns include POY, DTY, FDY and ATY.

[0016] The laser emitting device 1 is connected to a control switch for controlling the opening and closing of the laser emitting device 1. When the laser emitting device 1 is controlled to be in the on state, the laser emitting device 1 can emit a laser beam 4, which acts on the surface of the yarn, controls the energy of the laser beam 4, and makes the single filaments in the deformed yarn absorb energy, but does not melt, so that the deformed yarn can be transformed from a curled deformation state to a straight non-deformed state. When the laser emitting device 1 is controlled to be in the off state, the laser emitting device 1 does not emit the laser beam 4, so that the yarn at this time has a more fluffy structure. By controlling the length of time for the laser emitting device 1 to be turned on and off, the non-deformed section in the straight state and the deformed section in the fluffy state on the yarn are controlled. The laser beam does not cause damage such as burning to the yarn, but only allows it to be pulled to a straight state after absorbing heat.

[0017] Furthermore, the laser processing device further includes a first reflecting device 2 and a second reflecting device 3, which are used to reflect the laser beam 4 and adjust the path of the laser beam 4. The first reflecting device 2 and the second reflecting device 3 are both reflectors, and the path of the laser beam 4 can be adjusted by adjusting the reflection angle, so that the laser beam 4 can reach the target position and act on the surface of the yarn, so that the surface of the yarn at the position where the laser beam of the yarn is irradiated absorbs heat, but does not reach a melting state, so that the yarn at this position can be straightened.

[0018] Furthermore, the laser processing device further comprises a yarn feeding drum 5 and a winding drum 6. The yarn is led out from the yarn feeding drum 5, passes through the first clamping device 8, and then led out from the second clamping device 9, and the winding drum 6 winds the surface-treated yarn. The first clamping device 8 and the second clamping device 9 can be clamping rollers arranged in pairs.

[0019] Furthermore, the heat-fusible synthetic fiber textured yarn is polyamide filament, polyester filament, polypropylene filament, polyethylene filament or polylactic acid filament, and of course, it can also be textured yarn of other materials or different types of textured yarn. Figure 2 As shown in the figure, polyamide filaments are used, specifically nylon 6DTY, with a fineness of 75D / 72F. The yarn speed is 150 meters per minute, and the power of the laser emitting device 1 is 10W. The treated nylon 6 filaments are interwoven according to the plain weave to form a woven fabric such as Figure 3 As shown, it can be seen that the yarn in the fabric has a non-deformed section and a fluffy deformed section, so that the fabric has a different surface texture compared with the fabric interwoven with conventional nylon 6DTY filaments.

[0020] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
