Description

Synthetic fiber shoe sewing yarn and method for producing etc

In the present invention, after the adhesion of the shoe window and the outer skin of the shoe, a small gap is generated and the coated thread is used to fill the minute gap with a coating agent, and the most of the yarn is a dyeing yarn (dyeing yarn), and the coating does not discolor. It is a fastening method and a moisture-proof, and furthermore, if the frictional metal pipe of the cylinder after hitting the thread, the chemicals penetrate the yarn well, and the flexibility of the yarn has a good manufacturing method of the yarn.

The present invention will be described in more detail in the use of nylon filament yarns, vinylon fleece yarns, and polyester fleece yarns suitable for the characteristics of shoes (shoe shillongs, military shoes, gentleman shoes, etc.) (vinylone gentleman shoes, nylon yarn habi shoes). Characterized by the material of the yarn, the shoe stretches during wearing according to the physical properties of the thread, and when it is removed again, it has the characteristic of the function of returning to its original shape and stretching, coating, and physical processing during heat treatment. The coating liquid buried by dipping penetrates well and the water does not penetrate into the yarn, and the dyeing fastness is high and the flexibility is maintained while maintaining the shape of the yarn. will be.

Conventionally, in manufacturing a rope for fishing nets, in order to have a weight of a product braided with a synthetic resin material having high chemical resistance as the main material, a polyester-based synthetic resin film is passed through the adhesion roller of the liquid tank and the spray chamber is again While passing through a metal powder of about 150 to 200 mesh evenly sprayed on the front surface of the film, and then coated with an adhesive by a spray nozzle, the weight rope characterized in that it is combined in a 80 ~ 90 ℃ drying chamber with a weight tape with a moisture proof layer formed There is a known technique such as the 'apparatus and method for manufacturing a heavy rope for fishing nets' of Patent Application No. 83-2752 (announced 85-918).

There was only an improved method for processing and processing yarns with these different uses. The yarns that have been projected for this service are used only in natural fibers. Conventional techniques as described above have been applied to the subsea yarn industry, but there are no improved techniques of chemical fiber, which is suitable for the characteristics of shoes as a chemical fiber service.

So far, masa and polyester yarn are used.

The vinylon, nylon and polyester yarns that make up the yarn are different in characteristics. According to the characteristics of the thread sew shoes according to his characteristics. However, when the window and the top cover are attached using only the adhesive as if the thread is attached to the shoe by sewing machine without sewing the thread, it is broken when water is released after use for a certain period of time, and when the sewing thread is used, it is processed according to the characteristics of the thread. When sewing without sewing, there is a disadvantage that the thread bursts, and this causes the workability to be deteriorated, and if you just sew with the raw nylon yarn or polyester yarn, etc. The durability of the thread is reduced, and the density of the shoes around the sewing area is dense, so it becomes poor. The product is attached to the shoe window, the shoe cover, etc., or the shoes are sewn with unprocessed thread for a long time. When you have a lot of impact, the foot is swollen when this shock is received. This will increase your shoes. Depending on the situation, when removed, the size and shape do not return to their original shape. This is because the yarn stretches and the elasticity problem does not return to the size and shape of the product at the time of production. In general, dyed products will be discolored if not processed. This led to mass production of defective products.

The present invention is a condition of the material corresponding to the above to solve the above technical problem,

First, even if the thread is sewn, the shape of the thread is kept intact and the thread should not burst when sewing.

Second, it has elasticity suitable for the kind of shoes by processing with chemicals and conditions suitable for each yarn of nylon yarn, polyester yarn, and vinylon yarn. It is necessary to use coating chemicals, and in consideration of physical properties, it is necessary to use a coating method and an extension process for the yarn to remove napping, moisture resistance, and flexibility for easy sealing work.

That is, the present invention is intended to provide an improvement in dyeing fastness and strength while having the characteristics of the yarn such as the elasticity and shape stability and moisture resistance of the yarn.

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

Adjust the speed with the roller (5) to match the speed of the coated roller to settle in the chemical container, and through the second roller (6) through the third roller (7) of the first phase while the chemical liquid (11) Squeeze and wind the thread through the coating roller (1 or 1 ') under the coating roller (2, 2') (a thread length wound about 2 m between the rollers) and the hot air (8) of 70-90 ° C.

Two pairs of long rollers (1, 1 ', 2, 2') are installed and attached to both sides of the blow cylinder (4) to which the frictional metal pipe (3) is attached as necessary. The gap between the rollers of two pairs of threads is to be installed with the width of the impact cylinder. In other words, two friction metal pipes and a width less than the length of the blow cylinder are installed. The size of the friction metal pipe and the blow cylinder is about 50cm (four equals to 2m of the space between two pairs of wound rollers).

Wind the thread so that the iron coating roller and the iron coating roller 2m away from the installed device, and continue to rotate the iron coating rollers (1,1 ', 2,2') about 150 to 170 times. At this time, the blow cylinder (4) heats the frictional metal pipe (3) at about 60 ° C and continues to turn, and stretches the coating area while hitting the thread when it reaches the A and B parts (real thread, the point where the friction metal pipe touches). do. After that moment, the stretched thread is reduced (to its original length) when it reaches parts C and D (the point where the thread only touches the striking cylinder surface).

In other words, apply tension while penetrating the fluid deeply into the thread while drawing and striking like the contact of A and B parts.

When the stretching process with the iron coating roller becomes more than two pairs as shown in the drawing, the pair of cylinders is suitable because the impact cylinder tends to be broken (crushed) by the reflective elasticity of the tension of the thread.

Examples of the conditions suitable for the characteristics of the yarn by the processing step by the above device are listed as follows.

Example 1 polyvinyl alcohol fiber yarn,

Vinylon yarn (elongation 17-22%) 20's three-ply yarn super-twisted, and again the yarns three to 11 ply yarns left and right yarns respectively, and after hank dyeing and transfer to the coating machine 85% by weight of PVA, 15% by weight of wax (wax) is added to the water-soluble cotton yarn at a weight mixing ratio of 5.5 to 6 times water, and then hit with a cylinder at a temperature of 80 ~ 90 ℃ and the coating is completed, the natural fiber (e) and Become a beacon of the same quality.

The coated yarn of the P.V.A-based fiber as described above is rolled again to a ball winding machine or a universal winder to become a finished product. This product is used for sewing high quality shoes, steelworks work shoes and sandals.

Example 2. Polyamide fiber yarn,

Nylon (28-45% elongation) 840D (denier) (840D-420D-1260D) is combined with 840D / 4f ~ 840D / 6f and left and right edges simultaneously with 4 ~ 6 strands at the same time, and is wound into bobbins after hank dyeing.

In the coating machine, 40% by weight of adhesive, 10% by weight of wax, and 35-50% by weight of latex are selected, and the mixing ratio is 3.5 to 5 times, and the cylinder temperature is selected to 70 to 80 ° C. Wind the wound around the metal H bobbin in the winder while stretching slowly in the winder.

The coated yarn as described above is finished again by winding in a ball winder or a universal winder. This product is used for sewing basketball shoes and general work shoes.

Example 3. Polyester fiber yarn,

Polyester 250D (Denier), 500D, and 1000D are merged by the number of plunges, and the left and right simultaneouss are continuously fired as a CS, and the CS is 250D / 3-4f, 500D / 3-4f, 1000D / 3,4,5,6f, Hank dyeing (high pressure dyeing), bobbins in the winder and stretched yarn is transferred to the coating machine and blended with 10% by weight of adhesive 40% by weight binder (wax) and 50% by weight of latex and blended in water 4 to 5 times weight ratio. After coating at 80 ℃ temperature condition in the coater, set it with H bobbin in the setting machine, fix the drawing and shrinkage first, cool it to 60 ℃, and then apply the iron roller at 80 ~ 90 ℃ as the second coater.

The coated yarn (polyester filament) through the above process is required to stretch to some extent, so that the roller and the friction adhesive cylinder was selected as a metal and fixed by steam.

The coated thread is wound on a universal winder without ball winder or 1 to 2.5kg knots to become a finished product. Such a product becomes a shoe thread suitable for sewing such as boots, work shoes, jungle shoes.

Hwasumbong use Hwabongsa is to process the coating heat treatment according to the properties of the fiber in the three methods described above, because the type of yarn has different physical properties depending on the material of the shoe. Among these yarns, vinylon and nylon yarns are selected by a ball winding machine so that the thread is unrolled and pulled up by the arming force. When sewing, the sewing interval of the shoe becomes constant.

Fully sewing thread sewing the thick of the window and upper leather in the shoe, select silicone oil or mineral fiber to prevent heat generation and damage of the sewing needle, the adhesive, wax, latex (latex) has a chemical reaction As a result of the melting of the needle, it fills the needle hole and the re-sealed shoe enters the drying chamber to bond the bond, and the emulsion evaporates, and the existing chemical rapidly solidifies, resulting in full adhesion with the shoe, latex and other waxes.

In this way, the leather falls but the flower bud does not fall.

As described above, in the present invention, unlike the conventional yarns, vinylon yarns (PVA), nylon yarns, polyester yarns are joined, dyed, and stretched to undergo the same process as the above-mentioned fiber yarns In the manufacture of conventional shoes by attaching the adhesive is most often attached in this case, if worn for a long time, the shoe breaks and water seeps into. In addition, if you sew with a conventional flower thread, there is a small gap invisible to the eye and water is seeping into this gap. Therefore, the thread of the present invention, the yarn is filled with a small gap in the drug and to prevent the breakage, and also sewing thread used as the yarn should be used according to the color of the shoe, so the dyeing thread is mainly required because the dyeing fastness is coated It is so high that when normal dyes are discolored by sunlight, it does not discolor. In addition, if the yarn is dipped into the medicine container and applied by the blow cylinder while passing through the iron coating roller, the chemical penetrates into the thread and the water does not penetrate into the processed thread, and the flexibility is different from the conventional products. Flies And napping was eliminated by the coating process. Even if the thread is sealed (sewing), the shape of the thread is maintained as it is and is durable by processing suitable for the three types of yarns.

In the case of vinylon yarn, the elasticity is the lowest among general raw material yarns (17-22% elongation). The physical properties of the yarns are similar to those of natural fibers. By using the vinylon yarn, nylon yarn, and polyester yarn processed in the above method to manufacture shoes suitable for each characteristic, shoes are swollen when they have a high amount of exercise, that is, when the feet are shocked when exercising for a long time. This will increase your shoes. If you take off your shoes afterwards, they will return to their original size.
