Description

Method for producing hand-bonded yarns processed by FVA yarn (vinyllon) {Method for producing hand-sewing yarn by doubling and twisting poly vinyl alcohol spinning yarn}

The present invention relates to a method of manufacturing a male yarn by PVA-based vinylon spun yarn. The present invention will be described in more detail PVA in order to have elongation (elongation 12 to 26%) and elongation recovery in polymer PVA-based chemical fiber yarns having the same properties as less elasticity (elongation 1.5 to 2.3%) and supplement the shortcomings of the hemp A process of twisting and fusing a system of chemical fiber yarn aka vinylon spun yarn;

Dipping and heat-treating the heat in the bath solution;

The present invention relates to a method for producing a vinylon-based water seal (手 우수한) having excellent shrinkage (recovery force) internal sealing property through a process of heating and wax coating heat treatment at a predetermined temperature.

At present, one of the methods of manufacturing the yarn with a certain process treatment and special treatment for that purpose is to squeeze the polyamide filament yarn through a latex solution, press it with a squeegee roller, and dry it in a drying furnace. By maintaining the pressure drying temperature and the latex ratio of the yarn in the drying furnace under the proper conditions, the patent application No. 88-8236 (Notice) is similar to the manufacturing method of the polyamide-based latex coated yarn having excellent adhesion to the carcass layer of a soccer ball. There is a known technique such as No. 90-7654, 'Method for producing polyamide-based latex coating yarn', and another method is Patent Application No. 92-21061 (Notice No. 95-1656, 'Manufacture of Fire-Resistant Insulation Rope for Safety Belts'). Method '), the process of inserting a conventional fire-resistant insulation hose on the surface of the twisted rope of nylon yarn and put it in a vacuum furnace to heat 100 ~ 150 ℃, Due to the material properties of the fireproof insulation hose itself, there was a manufacturing method of the fireproof insulation rope for seat belts, which has an improved quality of supporting the hoses with a uniform thickness on the curved surface of the rod.

There was only an improved method of processing and processing yarns with these different uses, and until now the yarns used for this service were simply made of natural fiber yarn. There is a technology such as that applied to the industry of the prior art as described above, but there is no technology improved according to the characteristics of the shoe.

So far, masa and polyester yarn are used.

The polyester yarn used as a subsea yarn has only three dyes. This color is black, white and dark brown. When the thread was made with the color that matched the color of the shoe, the light color changed slightly using white and the dark color changed to black. The number of colors changing the color was less than five. But now more than 50 colors are required.

In the case of massage (process water content 12%, water content 20 ℃ 100RH, 23%), the shoes touch the ground, so if they contain moisture, they become susceptible to corruption. There is a tendency to prefer natural fibers in foreign countries, and the polyester fiber does not decay, but the hemp of natural fiber decay can be said to be a disadvantage. In summer, when you are working with water, you can easily wax because it is waxed with water.

In other words, if you wear shoes, your feet will increase by the weight of your body, that is, they will increase, and if you take them off, you will have to recover them. The work environment was not good at the time of work because dust was generated during work.

As the condition of the material which can correspond to this,

First, depending on the application, the coating relationship should be adhered to each other when leather and rubber are wrapped.

Second, depending on the usage, when maintaining the friction strength between the leather and the shoes, when the user walks for a long time due to the weight of the body, the foot should be increased due to the increase in the foot size. The role that should be maintained should be designed to match the temperature and chemicals uniformly because it can produce high quality shoes only when the heat treatment and coating wax condition that can play the role of stretching and tightening at the same time are perfect.

Third, because synthetic fiber is different from natural fiber according to the usage of the thread, it needs to be stretched as chemicals and temperature according to the physical properties of the thread because the thread needs elasticity and fixation (fixing to prevent elongation). This is because a fill is required.

That is, the present invention is intended to provide the elasticity (stretching and contraction), the inner lung resistance and the dyeing of the color and the strength to meet the demand.

The present invention relates to a new manufacturing method to solve the above problems.

Hereinafter, the manufacturing process of the present invention will be described in detail with reference to the drawings.

As a material of vinylon (process water content 5%, moisture content 95% RH 20 ℃, 10.0-12.0%) and dry shoes, elasticity is the least in the real world (elongation: flax: 1.5-2.3%, vinylon: 12-26% The vinylone yarn is the least elongated and invisible, so it can be twisted and complemented closely to the nature (touch) of natural fibers.

In detail, the suede processed by combining the vinylon spinning yarn can be color-matched to match the color of leather or shoe soles. If you release it, it will be restored. Knowing the principles of these shoes, they have to produce special products.

Therefore, special treatment (heat, medicine, process, wax, etc.) is performed according to the use of shoes. This process will be described below with reference to the drawings.

1st process

When the yarn made of Viuylon spun yarn 20's × 3 fila is left edged, and 4 strands of the left side filament are haphazard again, 12 strands of plywood are balanced. In the case of 24 strands of yarn, two 12 strands of yarn are combined.

2nd process

13-18% by weight of PVA, 1.5-3% by weight of forget-me-not and 0.5-1% by weight of sorghum (ammonia) were dissolved in a yarn obtained in the first step, followed by dissolving the remaining 81-84% of the bath solution. ) Adsorption on the sealed yarn to make the winding speed constant in a special coating machine, dry heat drawing with 80 ~ 90 ℃ hot air in the heated state of the cylinder temperature of 80 ~ 90 ℃, and apply blow at the same time. It becomes a yarn of the same properties as flax, which is a natural fiber without shrinkage (after the weaving).

3rd process

The yarn produced as described above is coated with wax again at a temperature of 80-90 ° C. At this time, the third-shrinkage (reduction shrinkage: stretched part when the shoe is removed) do.

For each process described in detail for the vinylon spun-sealed silk yarn produced by the first, second and third process described above, in the process of the first yarn-ply-twisted yarn, the three yarns of 20's of vinylon spun yarn are added together. Twist the plywood combined with these three strands to the left and then twist it together into four strands. Thus, a total of 12 strands of yarn are produced in a balanced state.

In other words, the first process is only twisting.

Generally, 20's are used to make it easier to insert the needle, and 5's or 10's are used to make the fibers thicker, so they are broken. And, there is a difficult point because the tip is not sharp to insert the needle. If it's more than 30's, the number of consecutive yarns can not be matched by coordination, and the thickness doesn't fit the service company.

Since this is an industrial use, fine yarns are not suitable because of their low strength. So 20's is the suitable thickness among 30's, 20's, 5's and 10's.

In the second process of adding bath solution and physical process, hot air and stretching process, 13 ~ 18% by weight of PVA, 1.5 ~ 3% by weight of forget-me-not and 0.5 ~ 1% by weight of water, 81 ~ 84% of remaining water Mix

If the forget-me-not is less than 1.5 ~ 3%, the PVA will not melt and it will not penetrate into the thread. If the forget-me-not is more than 1.5 ~ 3%, the thread will be muggy and smell bad.

And if you put too much less than 0.5 to 1% by weight of ammonia, that is, solubility is insufficient. Preferably it is melt | dissolved if it is between 0.5-1.5%. The pooled yarn is adsorbed on a solution mixed with forget-me-not, PVA, and water, followed by dipping. After that, the 24 windings are thicker than the 12, so it is late.

The dipping speed makes the thin thread quicker the dipping process and the thicker one. It should be late for the solution to adsorb sufficiently.

And the winding speed should be constant. Thereafter, the hot dipped in the roller wrapped in a hot air of the cylinder temperature 80 ~ 90 ℃.

After dipping, it is wound on the roller. In other words, dozens of threads are wound on the roller. When the blow is made, the dipped liquid can penetrate at the moment of being hit, but it may increase afterwards.

This will make the surface of the thread smoother and the temperature will increase, so there will be no brushing. Dry little by little it will act as hair.

In other words, when sizing, it is not a way to adjust the speed with only heat, but to blow the cylinder to dry it with heat, to allow the liquid to penetrate well, and to attach fine hairs between the threads.

And the long thread is rolled up and down in the roller, and it rotates on one side and keeps going on one side. And before winding, the elastic yarn is produced and the necessary dyeing is done before waxing.

PVA and skin core layer dyeing are processes before waxing.

The temperature of a wax is suitable for 80-90 degreeC, and if it raises more than that, plywood twists and falls. Only when the temperature is appropriate is the 3rd contraction, or reduction contraction. (When you take off your shoes after wearing them, they will return to their original shape when they are not used.)

Thread the processed threads together and pull them by hand so that they will not retreat back when released. Since the thread is stretched, it cannot be returned. At the same time, the water does not penetrate the needle marks by the wax and the hole of the shoe needle is filled at the same time, so it does not leak water and maintains the friction strength.

Otherwise it breaks and runs away.

However, waxing does not break even when wrinkled, to preserve the life of the yarn.

As described above, in the present invention, unlike the conventional polyester fiber and hemp fiber, vinylon yarn (PVA) (property: completely resistant to mold) is combined with a vinylon water suture through an appropriate process in the same manner as the above process. By manufacturing the color can produce a lot of color demanded by the consumer compared to the past, and wearing shoes, the foot is stretched by the weight of the body, so the shoe stretches, but if you take off, it will only increase in natural fibers, but it will return to normal. And since shoes are on the ground, they tend to rot when they are hydrated, and natural fibers tend to rot. However, the fiber is processed by the method according to the above process, and in the case of export, in response to the preference for natural fiber products, it has a characteristic close to natural fiber and does not decay. In addition, there is no dust (dust) from natural fibers during shoe work, contributing to the improvement of working environment.
