Description
Technical Field
The invention belongs to the field of sewing of industrial sewing machines, and relates to a preparation method of a threading guide wire for a sewing machine.
Background
At present, in the sewing process of an industrial sewing machine, threading is a difficult problem, and a sewing thread on a sewing machine can generate normal stitches in the sewing process only by passing through a plurality of thread passing holes and an internal mechanism of the machine.
Due to the development and the transition of the market, the types of sewing threads related to sewing are more and more at present, for example, various threads such as elastic threads of silk threads and the like cannot normally pass through all threading holes and mechanisms on a sewing machine, most of factories generally adopt metal tweezers to clamp the thread segments for delivering and threading, a large amount of time is wasted, the efficiency is low, the tweezers often poke the thread passing holes of the machine or damage internal parts of the machine and touch needles and the like, so an auxiliary tool capable of threading is urgently needed at present, but the existing threads basically cannot play the role of a convenient threading tool, and the guide wire is specially developed and manufactured.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a low-cost and durable threading guide wire for a sewing machine.
The purpose of the invention can be realized by the following technical scheme:
a method of preparing a threading guide wire for a sewing machine, said method comprising the steps of: firstly, processing the nylon protofilament by a fluorocarbon coating, cutting, folding and tightly twisting the nylon lead, then heating the nylon lead, freezing and shaping, and finally soaking in a lubricant to obtain the threading guide wire.
In the above method for preparing a threading guide wire for a sewing machine, the fluorocarbon coating layer is specifically: uniformly covering a coating containing fluorocarbon molecules on the surface of the nylon thread, and then carrying out ultraviolet irradiation curing for 3-8 min.
Preferably, the thickness of the coating containing fluorocarbon molecules is 1-3 um.
In the above-mentioned method for preparing a threading guide wire for a sewing machine, the heating process is divided into preheating and secondary heating.
In the above method for preparing threading guide wire for sewing machine, the preheating temperature is 45-55 deg.C, and the time is 0.5-1.5 min. The invention is preheated at 45-55 ℃ to cause the nylon yarn to generate tension, if the temperature is too high, the yarn tension is too high to manufacture products or directly break, and if the temperature is too low, the yarn cannot have enough twisting space to break.
Preferably, the nylon yarn is twisted by a motor-driven rotor after preheating.
In the above method for preparing threading guide wire for sewing machine, the second heating temperature is 65-75 deg.C, and the time is 1-3 min. The invention carries out setting on the silk thread at 65-75 ℃, if the temperature is too high, the twisted silk thread is over-expanded and loosened, and if the temperature is too low, the bonding setting can not be carried out.
In the above method for preparing threading guide wire for sewing machine, the freezing and shaping temperature is-5-15 deg.C, and the time is 1-3 h. The frozen sizing part has the advantages that the further shrinkage and solidification are that the two threads are in a firmer bonding state, and the threads can not be scattered along with the change of the external environment after being stably sized.
In the above-described method for preparing a thread guide wire for a sewing machine, the lubricant is white oil.
In the above method for preparing a threading guide wire for a sewing machine, the soaking time is 25-35 min.
The nylon yarn is soaked in the white oil, so that the nylon yarn not only can play a role in softening and solidifying but also can increase the lubricating and passing performance of the yarn.
Compared with the prior art, the invention has the following beneficial effects: the threading guide wire for the sewing machine is prepared by the method, the threading is just performed by the thread guide wire with hardness and hardness, the thread guide wire does not damage the thread passing holes of the machine, the thread segments can pass through all the thread passing holes of the machine just without being thick, thin and scattered, the threading guide wire is durable after being processed, the threading difficulty of various threads is reduced, the working efficiency is greatly improved, the service life of the machine lifting machine is well protected, and the threading guide wire is simple in preparation method and suitable for large-scale industrial production.
