The versatile eco-friendly cup carrier 100 includes a support part 110 that can support the cup on a large square thin fabric, an arc cutout 120 and a side cutout 130, as shown in FIG. Can include.

It is formed by partially incision in a square thin fabric, but as illustrated, an optimized structure is provided to minimize unnecessary waste while supporting the cup so that it does not incline using a square fabric. Here, a square is exemplified, but it may be manufactured in a rectangular or other polygonal shape.

The central part of the cup carrier 100 forms a support part 110 having a certain area to support and support the cup, and an arc cutout 120 is formed on a concentric circle around the support part 110. I can.

About four circular arc cutouts 120 are formed in an arc of a predetermined length preferably on a concentric circle, and in FIG. 1, they are arranged in the directions of 0°, 90°, 180°, and 270°.

And it may be desirable that the four arc cutouts 120 have the same arc length.

And a plurality of side incisions 130 are formed along a concentric circle at a position whose diameter is larger than that of the circular incision 120 based on the center of the support portion 110, and the side incisions 130 have a diameter at regular intervals. It can be formed at each enlarged position.

In addition, the side cutout 130 is formed to include rounded extension lines 132 at both ends of a straight line, and about four are cut apart by a predetermined distance with the same length on each concentric circle.

Further, on the concentric circle whose diameter is enlarged, the marginal cutouts 130 may be repeatedly disposed so as not to overlap each other again, as shown in FIG. 1.

That is, when the variable incision 130 is disposed in the 0°, 90°, 180°, and 270° directions on one concentric circle, it is disposed in the 45°, 135°, 225°, and 315° directions in the next concentric circle to form a cross repetition. It becomes.

Meanwhile, the cup carrier 100 as described above is made of a resin in which the material is made of a spunbond nonwoven fabric, preferably polyethylene terephthalate having a melting point of 275°C or higher and polybutylene terephthalate having a melting point of 245°C or higher. A first staple fiber and a second staple fiber made of a polyester resin having a melting point lower than that of the polyethylene terephthalate of the first staple fiber is 60° C. or more, and the first staple fiber and the second staple fiber are mixed It is manufactured by web lamination and heat bonding.

The first staple fiber is produced by blending and spinning while simultaneously supplying 80 to 95% by weight of polyethylene terephthalate and 5 to 20% by weight of polybutylene terephthalate to an extruder through a raw material feeder and melting.

At this time, the intrinsic viscosity (IV) of polyethylene terephthalate in the first staple fiber is preferably 0.6 to 0.7 and the intrinsic viscosity of polybutylene terephthalate is preferably 0.7 to 0.8.

When the content of polybutylene terephthalate in the first staple fiber exceeds 20% by weight, spinning due to cutting during filament production is unstable due to the fast cooling rate of polybutylene terephthalate, and when it is less than 5% by weight, orientation Since it cannot play a sufficient role as an inhibitor, the decrease in filament density is not large, and thus the effect of improving molding is not large.

And the second staple fiber is produced by spinning a low melting point copolyester, and the low melting point copolyester is mixed with an additive such as adipic acid or isophthalic acid in the polyester polymerization process, so that the melting point of the first It is adjusted to be lower than 60 ℃ lower than short fiber polyethylene terephthalate.

The first staple fibers and the second staple fibers are 85 to 95: 5 to 15% by weight of the blended fiber to be spun to form a blended yarn, and when the content ratio of the second fiber is less than 5% by weight, it is melted to serve as an adhesive. Because the amount of the two-stage fiber component is small, the strength and elongation of the nonwoven fabric is lowered, and if the amount exceeds 15% by weight, the adhesive component is excessive, and due to excessive adhesion between the filaments, a lot of filament breakage in the tufting process occurs. It is difficult to use as a carrier for carrying cups because the strength and elongation of the cup are lowered.

Thus, the filament spun in the form of mixed fiber is sufficiently stretched so that the spinning speed is 4500-5000 m/min using a high-pressure air stretching device to produce short fibers having a fineness of 4-10 denier. If the fineness is less than 4 denier, the staple fibers are too thin and the number of staple fibers per unit area increases, causing a lot of damage to the staple fibers in the tufting process, which causes deterioration of properties.If the fineness exceeds 10 deniers, the nonwoven fabric is uniformly manufactured. It becomes difficult to do.

The short fibers produced by the honseom spinning are laminated in a web form and are thermally bonded using two high-temperature/high-pressure calender rolls or embossed rolls used in conventional non-woven fabric manufacturing, or non-woven fabric using an adhesive method using hot air. To manufacture.

In the case of using a heat setting device that sprays hot air such as a tenter as the hot air bonding method, the temperature of the hot air device is preferably the same as the melting point of the low melting point copolyester, which is a second-stage fiber. The basis weight of the nonwoven fabric is suitable for 100~140 g/㎡.

As described above, since the first staple fiber and the second staple fiber are made of the same material, the low-melting copolyester of the second staple fiber is melted in the heat bonding step to obtain the polyester fibers of the first staple fiber having a relatively high melting point. It works more effectively to improve the strength of the nonwoven fabric by bonding easily with the polyester of the first short fiber, which is the same material, while bonding to each other.

Therefore, since the spunbond nonwoven fabric of the present invention is manufactured by heat bonding, short fibers are thermally bonded to each other even without separate processes such as needle punch, so the manufacturing process of the nonwoven fabric is simple and the filament fibers are prevented from being damaged in the needle punch process. It is possible to obtain a spunbond nonwoven fabric with a bulky structure because the fiber is bonded by heat rather than an external force.

Tensile strength is 30~36 kgf/5cm, tear strength is 10~11 kgf, and elongation at 185℃ is 85% or more, specifically 75~90%, so it has moldability and durability at high temperature. It has excellent properties.

The operation of the multi-use eco-friendly cup carrier according to the present invention having the above configuration will be described with reference to FIGS. 2 to 4.

When the cup is placed on the support part 110 and each corner is pulled together, the circular cutout 120 and a plurality of side cutouts 130 are developed upward around the support part 110 to surround the cup.

And each corner part can be safely transported by acting as a handle in a state that does not fall out by crossing each other.

In FIGS. 2 to 4, embodiments may be provided according to various colors and shape of handles of corners, as shown.

Due to the above-described functions, it is made of spunbond nonwoven fabric so that the structure and manufacturing process are simple, so that cost can be reduced, and environmental friendliness, elasticity, and durability are improved.

In addition, the spunbond nonwoven fabric is economical because it can be used for many purposes, has excellent storage, and is formed so that anyone can safely support the cup and move it, thereby improving convenience.

In the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should be determined by the scope of the claims and equivalents as well as the scope of the claims to be described later.
