Description

Curtain with improved retention duration of shape and manufacturing method thereof

The present invention relates to the manufacture of shape-memory curtains, and more particularly, to a curtain with an improved preservation duration of a shape so that a constant shape can always be maintained even after movement of the curtain, and a manufacturing method thereof.

In general, curtains have a high demand for interior functions as well as a light-shielding function as interest in indoor interiors has recently increased.

In addition, it is a trend to apply various fabrics to curtains along with the development of fabrics with excellent light-shielding functions.

Curtain pleats are required for the curtain's light-shielding function and interior function, and it is easy to walk after hanging the curtain according to the shape of the pleats, and comfort and beautiful appearance according to the curtain's drapery are important elements of the interior.

In order to make the pleats of these curtains, methods such as watering, tying, and inserting auxiliary devices are used as temporary means, and a bow knot-shaped tuck is formed at the top of the curtain to form a natural drapery of the fabric. Although this method is common, there are disadvantages in that natural wrinkles are not formed depending on the type of fabric, and economical efficiency is low due to the large amount of fabric required.

As a conventional technique for forming wrinkles on curtains, a method of forming an S-shaped drapery by performing resin processing and press processing on a curtain fabric has been disclosed.

Alternatively, a method of forming an S-shaped drapery through steam spraying has been disclosed.

However, since the formed curtain creases are not maintained during repeated opening and closing and washing of the curtains, a user has to iron again during the process of replacing and washing the curtains in order to maintain a continuously smooth drapery.

Hereinafter, each process will be described in detail.

[Process of fixing fabric for curtains (S1)]

Place the fabric (F) for curtains on the bending forming jig 100 and fix it.

The curtain fabric (F) is a fabric used for normal curtains, and fabrics made of special materials such as blackout and flame retardant may also be applied.

That is, it can be processed into a shape-memory curtain in which the shape of pleats is maintained regardless of the type of fabric and original texture.

Of course, depending on the type of fabric, the time of the vacuum compression process, the amount of heat, and the number of repetitions of compression may be changed.

The curvature forming jig 100 to which the fabric F for curtains is fixed may be individually configured as an S-shaped curve or a W-shaped curve. Alternatively, the W type and the S type may be alternately formed.

S-shaped curtains have the same shape as the letter S because the pleated sections of the curtains are connected only by curved surfaces.

A W-shaped curtain is one in which the pleat-forming sections of the curtain are connected only in straight lines to form a shape similar to the letter W.

[Shape memory process (S2)]

The fabric for curtains (F) fixed to the bend-forming jig 100 is placed in a vacuum chamber (V) and vacuum-compressed so that wrinkles are formed in the fabric for curtains (F) according to the curvature of the bend-former jig 100.

The inside of the vacuum chamber (V) is maintained at a vacuum pressure of -0.085 MPa to -0.095 MPa using a vacuum pump.

A plurality of flow passages 130 are formed inside the bend forming jig 100 to perform vacuum suction, and a plurality of vacuum holes 132 communicating with the flow passage 130 are formed on the upper surface of the bend formation jig 100.

Therefore, when vacuum pressure is applied, the curtain fabric is brought into close contact by exerting a suction force on the upper surface of the bending jig 100.

In the shape memory process (S2), after the curtain fabric (F) is loaded into the bending forming jig (100), the pressure pad (200) is in close contact with the operation of the pressure unit (300), and a vacuum is placed in the vacuum chamber (V). It is maintained for 30 to 50 minutes while the pressure is maintained so that wrinkles are formed.

In the bending jig 100, a first protrusion 110 and a first concave portion 120 having an arc or triangular cross section are continuously formed to form a waveform.

The pressure pad 200 is formed with a second recess 210 and a second protrusion 220 so as to be complementary to the first protrusion 110 and the first recess 120 of the bending forming jig 100 .

A heater H for heating is built inside the first protrusion 110 of the bending jig 100 to heat the first protrusion 110 .

The wrinkle formation time of the fabric for curtains (F) may be shortened by heat deformation by applying heat at approximately 80 to 120° C.

The pressing unit 300 of the shape memory process (S2),

A shaft 310 formed vertically on the upper part of the pressure pad 200 and having a thread on the outer surface, a first gear 321 screwed on the upper part of the shaft 310 and having teeth on the outer surface, a driving unit composed of a second gear 322 geared to the gear 321 and a motor 323 connected to the second gear 322;

a disk 330 attached to the outside of the shaft 310;

A caliper 340 that exerts a braking force by being in contact with the outer surface of the disk 330;

an oil tank 350 that provides hydraulic pressure so that the caliper 340 is brought into close contact with or separated from the disk 330 by controlling the on-off operation of the caliper 340;

A hydraulic hose 360 connecting the oil tank 350 and the caliper 340 and filled with oil therein;

It is configured to include; a signal transmission unit 370 that controls the on-off operation of the oil tank 350 and interlocks with the detection sensor 371 formed at a position corresponding to the bottom dead center of the pressure pad 200.

In addition, a footrest 372 connected to the motor 323 and formed around the press unit 300 so that the foot can be placed on it;

An emergency stop button 373 is formed on the top of the footrest 372 to generate a stopping force by stepping on the foot,

When the emergency stop button 373 is turned on, power to the motor 323 is cut off, so that the operation of the pressurization unit 300 can be stopped.

[Wrinkle fixation step (S3)]

After opening the vacuum chamber (V), the wrinkled fabric (F) for curtains is placed on the lower cradle (420) on which a plurality of first rollers (R1) are arranged in parallel.

The upper holder 440 in which the plurality of second rollers R2 circumscribed by being inserted between the plurality of first rollers R1 are placed in parallel is brought into close contact with the lower holder 420 so that the curtain fabric F is blotted. .

Thereafter, while the vacuum chamber (V) is closed, high-temperature steam is applied thereto to heat the curtain fabric (F) so that wrinkles are fixed.

After completing the pleat fixing process, coolant is supplied to the inside of the second roller (R2) of the upper holder (440) so that the second roller (R2) is cooled so that the pressed curtain fabric (F) is rapidly cooled.

[Cooling process (S4)]

After taking out the wrinkled curtain fabric (F) from the vacuum chamber (V), spread it on a holder and cool it at room temperature.

[Waterproof coating layer forming step (S5)]

After the wrinkled curtain fabric (F) is transferred to the coating processing unit, the first liquid is sprayed on the outer surface of the curtain fabric (F) with a sprayer to form a waterproof coating layer, and then cured.

According to one example, the first liquid agent, urethane polymer 10 ~ 20wt%; 20 to 30 wt% of acrylate having a hydroxyl group; 20-25wt% silicone-based fabric softener mixed with amino-modified silicone and glycerin; Acrylate monomer 10 ~ 20wt%; Toluene 10-20wt%; 5 to 10 wt% of a fluorine-based coating agent;

The urethane polymer is a first composition of any one or two or more selected from the group consisting of polyethylene glycol, polypropylene glycol, and polyester polyol, and any one selected from the group consisting of xylene diisocyanate, diphenylmethane, and dicyclohexylmethane Or it is obtained by mixing two or more second compositions.

The hydroxy group-containing acrylate is obtained by mixing any one or two or more selected from the group consisting of hydroxycyclohexyl acrylate, hydroxycyclooctyl acrylate, and pentaerythritol triacrylate.

The acrylate monomer is obtained by mixing any one or two or more selected from the group consisting of decyl methacrylate, isodecyl acrylate, isobornyl acrylate, hexadecyl acrylate, and bisphenol A diacrylate.

[Process of Forming a Deodorant Layer (S6)]

After the waterproof coating layer is formed, the curtain fabric (F) is dried for a certain time, transferred to the deodorant spraying unit, and then the second liquid is sprayed on the outer surface of the curtain fabric (F) with a sprayer to form a deodorant layer on the surface.

The second liquid agent,

Any one or two or more 2-1 liquid agents selected from the group consisting of pine needle extract, moth extract, and green tea extract;

A 2-2 solution prepared by mixing EM stock solution with sugar, sea salt, potassium carbonate, surfactant, and anhydrous ethanol;

It is made by mixing any one or two or more liquid agents selected from the group consisting of lavender extract, rosemary extract, and peppermint extract.

EM (effective microorganism) is an abbreviation for useful microorganisms, and is an enzyme product made by mixing beneficial bacteria such as lactic acid bacteria and yeast. Its main functions are deodorization, contamination purification, and sterilization.

Preferably, 10 to 20 wt% of the 2-1 liquid agent, 40 to 50 wt% of the 2-2 liquid agent, and 35 to 50 wt% of the 2-3 liquid agent are mixed.

If the 2-1 liquid agent is less than 10 wt%, the antibacterial activity is reduced, and if it is 20 wt% or more, there is a concern that the efficacy is reduced because it is too excessive.

If the content of the 2-2 liquid agent is less than 40 wt%, the deodorization and sterilizing power is reduced, and if the content is more than 50 wt%, there is a risk of deterioration in efficacy due to excessive content.

If the 2-3 liquid agent is less than 35 wt%, the deodorizing power is reduced, and if it is 50 wt% or more, there is a concern that the efficacy is reduced because it is too excessive.

Therefore, by making the fabric (F) for curtains on which the waterproof coating layer and the deodorant layer are formed have shape memory properties for the wrinkles (F-2), the overall wrinkles can be maintained for a long time, resulting in a beautiful appearance. It can exhibit insect repellency (see FIG. 5).
