It is aimed to protect the IT products and provide the aesthetics of the material itself by providing the fabric used for improved IT product case and bag.
Further, it is an object of the present invention to provide a water-repellent function to the fabric so as to avoid inconvenience in daily life.
In order to attain the above object, the present invention is characterized in that high strength heat resistant fiber capable of withstanding an endurance temperature of 200 to 300 DEG C is used, and aramid fiber, PBO {poly [2,2'- (m-phenylene) -5,5'benzimidazole ]} Fiber and PBI (polybenimidazole) fiber, and a water-repellent layer formed on the durability protection layer, wherein the durability protection layer comprises the high-strength heat- And a hot melt adhesive layer is further provided under the protective layer through laminating, and a method of manufacturing the same.
The aramid fiber used herein has a yarn strength of 23 g / de or more, a tensile strength of 5,000 N / 5 cm or more, a wear strength of 30,000 times or more and 200 denier (de) or less.
The heat-resistant fibers may be used in an amount of 50-100 wt% based on the total weight of the durable protective layer and 0-50 wt% of the synthetic fibers. The synthetic fibers may be nylon 6, nylon 66, UHMW-PE (Ultra High Molecular Weight Polyethylene), carbon fiber (CARBON FIBER), and rayon (Regular and FR Rayon) or a mixture thereof.
According to the present invention configured as described above, it is possible to provide a high heat-resistant, high-strength, lightweight fabric, which can withstand 200 to 300 ° C even when continuous surface friction occurs, Direct bonding using high-frequency and thermocompression after die-cut is easy, and productivity can be improved due to high dimensional stability even in continuous high temperature.
In addition, the fabric has an effect of providing a role of safely protecting the electronic products from external friction and impact by using the aramid material having excellent abrasion strength.
1 is a cross-sectional view of a two-layer high heat-resistant high-strength lightweight fabric according to an embodiment of the present invention.
2 is a cross-sectional view of a 3-layer high heat-resistant high-strength lightweight fabric according to another embodiment of the present invention.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in Fig. 1, the fabric using the heat-resistant fiber according to the present invention has an
The durability protection layer comprises a heat resistant fiber selected from aramid fiber, PBO {poly [2,2'- (m-phenylene) -5,5'benzimidazole] fiber and PBI (polybenimidazole) When the heat-resistant fiber is an aramid fiber, it is preferable that the yarn strength is not less than 23 g / de, the tensile strength is not less than 5,000 N / 5 cm, the abrasion strength is not less than 30,000 times and not more than 200 denier (de) And weft density of about 5 to 15 bands / cm, respectively, and a tensile strength of 5,000 to 10,000 N / 5 cm.
When the monofilament is less than 0.7 denier, it is difficult to weave the multifilament fabric. When the monofilament is more than 1.6 denier, the woven fabric is wound on the outside It is vulnerable to shock.
In this case, it is preferable that the heat-resistant fiber is contained in an amount of 50-100 wt% based on the total weight of the durable protective layer so as to withstand a continuous surface friction temperature of 200 to 300 ° C In order to withstand a high temperature up to 300 ° C, it is preferable that the heat resistant fiber containing aramid fiber is contained in an amount of 85% by weight or more.
Synthetic fibers are used for electronics case materials such as nylon 6, nylon 66, UHMW-PE (Ultra High Molecular Weight Polyethylene), carbon fiber (CARBON FIBER), rayon (Regular & FR Rayon) It is preferable that they are composed of suitable fibers in combination and are contained in an amount of 0 to 50% by weight based on the total weight of the durable protective layer.
The heat-resistant fibers in the durable protective layer can be woven in various ways such as plain weave, twill weave, water weave, double weave basket weave, etc., and by mixing heat resistant fibers with nylon, polyester, UHMW-PE, CARBON FIBER, We write in the same way when writing.
When the fabric is finished, the refining process must be carried out in order to remove the emulsion or foreign matter. This is because the adhesion of the oil repellent or foreign matter adhered to the surface during the water repellent and antifouling treatment weakens the bonding strength between the water- And the refining process uses a scouring agent mixed with a surfactant such as NaOH or Na 2 CO 3 at 40 to 100 ° C.
After refining, it is washed and dried to obtain final fabric.
The material of the water-repellent layer is perfluorinated compounds (PFCs), that is, a compound that emulsifies fluorine. The surface tension of the surface of the fabric is controlled to have a repulsive property against water or water droplets. Thereby protecting the heat-resistant fibers constituting the durable protective layer from water, thereby providing excellent durability and abrasion resistance as well as antifouling properties.
When the hot-melt adhesive layer is provided, the durable protective layer and the hot-melt adhesive layer are laminated to each other so that the hot-melt adhesive layer can be directly adhered to different kinds of materials when manufacturing the case of the electronic device.
delete
The resin constituting the hot-melt adhesive layer is prepared by laminating a polyether sulfone (PES) film, a polyacrylamide (PA) film, a polyethylene (PE) film or a thermoplastic polyurethane (TPU) film on the sheet or coating a polyurethane (PU) film on the sheet.
This hot-melt adhesive layer has a thickness of 30 to 300 占 퐉 and a wear strength of 35,000 times or more.
Meanwhile, the durable protective layer and the hot-melt adhesive layer are adhered to each other at a temperature of 70 to 150 ° C. using a moisture-curing adhesive in a powder state of 3 to 30 g / m 2 in the laminating process. The moisture-curing adhesive is aged at a temperature of 30 ± 10 ° C. and a humidity of 80 ± 10% for 6 to 24 hours so that the moisture hardening strength is increased to improve the adhesive strength. Thus, a high heat-resistant high-strength lightweight fabric can be produced by laminating.
The laminating can be performed by a dot method or a mesh method. In the dot method, the adhesive is applied to the lower layer at regular intervals and is bonded to the upper layer, It is an effective laminating method because it exhibits excellent functions not only in terms of efficiency but also in soft touch development.
On the other hand, the mesh method has a merit of being excellent in adhesiveness by being applied to a kind of whole surface.
The adhesive used herein is preferably a thermoplastic adhesive containing an ethylene vinyl acetate resin, a polyolefin resin, a polyvinyl alcohol resin, an acrylic resin or a polyamide resin as an effective component, preferably a hot melt adhesive do.
The hot-melt adhesive is a thermoplastic adhesive that does not use water or a solvent but is melted by heat and adhered in a solid state, and has an advantage of being easily applied to dot-type laminating while hardly affecting between multi-layer fabrics.
Hereinafter, a test example of a fabric using heat-resistant fibers according to the present invention will be described.
[Method of Measuring Wear Strength]
In order to measure the comparison abrasion strength between the fabric of the present invention and general sports wear fabrics, the test piece breaking point was measured by the Martindale Method according to ISO 12947-2.
The specimens shall be of a diameter of 38 mm and shall have 5 specimens per each fabric. The total effective wear load (ie the weight of the entire specimen holder and the weight of the specimen) shall be 595 ± 7 g (nominal load of 9 kPa) And the average value is measured five times.
The abrasion test continues until the specimen breaks.
A typical test piece failure point is defined as follows. When two strands are completely cut off from the first fabric, when one strand is broken in the second strand and the hole appears, when the file is completely worn out on the third strand, on the fourth strand, And the diameter is at least 0.5 mm or more.
The test conditions were a standard condition for the fiber test, namely a temperature of 20 ± 2 ° C and a relative humidity of 65 ± 2%.
[Example]
Among the two-layer fabrics (composed of the durable protective layer and the water-repellent layer) which are the most basic in the present invention, only the aramid fiber was used as the durable protective layer. At this time, the aramid fiber has a yarn strength of 23 g / de or more, a tensile strength of 5000 N / 5 cm or more and 200 denier (de).
Layer nylon fabric 200de and the two-layer polyester fabric 200de were used as comparative fabric 1 and comparative fabric 2, respectively, for comparison with the two-layer fabric of the present invention, and the abrasion strength was measured under the same conditions, Respectively.
It can be seen that the two-layer fabric of the present invention is superior in abrasion strength compared to the comparative fabrics.
Therefore, according to the present invention, it is possible to provide a high heat-resistance high-strength fabric, and a hot melt adhesive film is laminated on the IT case to manufacture a three-layer high heat- It becomes possible to directly adhere to a material for a different type of case using a high frequency and a thermocompression.
