A production process of flame-retardant sewing threads based on mutual interweaving comprises the following steps: the production process is suitable for the flame-retardant sewing thread based on mutual interweaving, and comprises the following steps:
s1: the flame-retardant sewing thread base layer and the flame-retardant sewing thread surface layer are produced into the flame-retardant sewing thread through a knitting machine, wherein the flame-retardant sewing thread base layer comprises polyester threads and silk threads, and has good heat-resistant waterproof and smooth and soft surface effects;
s2: after the flame-retardant sewing thread is produced, the flame-retardant sewing thread is wound through the winding rod, and the flame-retardant sewing thread is straightened to improve the strength and the quality of the flame-retardant sewing thread;
s3: carrying out color matching dyeing and post-treatment on the manufactured flame-retardant sewing thread in a dyeing workshop;
s4: and (4) placing the dyed flame-retardant sewing thread in drying equipment for drying, and then taking out a finished product for use.
The working principle is that most of the existing sewing threads do not have the effects of flame retardance and water resistance, so that finished products made of the sewing threads are rapidly ignited when being burnt, and a fire disaster is easily caused, when the flame-retardant sewing threads are required to be produced, the flame-retardant sewing thread base layer 23 and the flame-retardant sewing thread surface layer 24 are placed inside the knitting machine 4, the knitting machine 4 works, the flame-retardant sewing thread base layer 23 and the flame-retardant sewing thread surface layer 24 are knitted together to form the flame-retardant sewing threads, the novel flame-retardant sewing threads have the advantages of flame retardance, water resistance, skin friendliness, softness and the like, one end of each flame-retardant sewing thread penetrates through the inside of the sliding block 34 and is fixedly connected to the side end of the winding rod 27, the first rotating block 26 is driven to rotate by opening the motor 25, the first rotating block 26 drives the winding rod 27 to rotate, and the winding rod 27 is enabled to wind the flame-retardant sewing threads, when the motor 25 rotates, the belt 32 is sleeved at the output end of the motor 25, the screw rod 33 is driven to rotate through the belt 32, the screw rod 33 is connected with the sliding block 34 through the screw rod nut pair, so that the sliding block 34 drives the flame-retardant sewing thread to slide up and down to be uniformly wound on the end part of the winding rod 27, and the problem of uneven thickness of the flame-retardant sewing thread in the winding process is solved; when the winding rod 27 needs to be installed, one end of the winding rod 27 is inserted into the clamping groove 51, the extrusion guide plate 52 is pushed upwards to slide upwards, the first spring 53 is pushed to generate elastic force, then the other end of the winding rod 27 is inserted into the sliding groove 55, along with the insertion of the winding rod 27 into the sliding groove 55, the extrusion locking block 57 retracts into the telescopic cavity 58 to extrude the second spring 59 to generate elastic force, when the locking groove 56 is aligned with the telescopic cavity 58, the second spring 59 generates elastic force to push the locking block 57 to be inserted into the locking groove 56 to be clamped and fixed, the problems of shaking and deviation when the winding rod 27 rotates are avoided, and the winding efficiency of the flame-retardant sewing thread is reduced; after the flame-retardant sewing thread is wound, the motor 25 is turned off, the pull ring 63 is pulled to pull the lock block 57 into the telescopic cavity 58 through the pull rod 62, the winding rod 27 is pushed upwards, the winding rod 27 slides out of the sliding groove 55, when the winding rod 27 slides upwards, the other end of the winding rod 27 slides upwards to extrude the guide plate 52, the guide plate 52 extrudes the first spring 53 to generate elasticity, when the winding rod 27 slides out, the other end of the winding rod 27 is pulled out, the winding rod 27 is taken down and placed into a dyeing device for dyeing, and the next production is carried out; when the winding rod 27 winds the flame-retardant sewing thread, due to the fact that the thread outgoing efficiency of the knitting machine 4 is high, the thread of the flame-retardant sewing thread wound on the surface of the winding rod 27 is loosened, the quality of the flame-retardant sewing thread is affected, the flame-retardant sewing thread is inserted into the first threading block 72 through the installation of the electric push rod 71 and the first threading block 72, then the other end of the flame-retardant sewing thread penetrates through the sliding block 34 and is fixedly connected to the end portion of the winding rod 27, when the winding rod 27 winds, the first threading block 72 slides downwards to pull the flame-retardant sewing thread to slide downwards, the flame-retardant sewing thread is continuously tightened, and the tightness of the flame-retardant sewing thread wound on the surface of the winding rod 27 is improved; when the first threading block 72 slides downwards to pull the flame-retardant sewing thread, the air bag 73 is extruded, the telescopic rod 74 is installed to guide, so that the air in the air bag 73 is circulated to the rod cavity of the air pipe 75 through the telescopic rod 74, when the air in the rod cavity of the air pipe 75 is increased, the push plate 76 is pushed to slide upwards, the push plate 76 drives the push rod 77 to slide upwards, the push rod 77 drives the second threading block 78 to slide upwards, and when the second threading block 78 slides upwards, the flame-retardant sewing thread is straightened by matching with the first threading block 72, so that the strength and the force of the flame-retardant sewing thread wound on the surface of the winding rod 27 are improved, and the quality of the flame-retardant sewing thread is further improved; when fire-retardant sewing thread slided in the inside of second threading piece 78, the tip of second threading piece 78 can cause wearing and tearing to fire-retardant sewing thread, leads to fire-retardant sewing thread's quality to reduce, has blotter 81 and wear-resisting piece 82 through the internally mounted at second threading piece 78, protects fire-retardant sewing thread, avoids causing the problem of wearing and tearing.
