Description

[0001] NON-TOXIC SUN-SHADE BLIND AND MANUFACTURING METHOD FOR AUTOMOBILE USE [0002]

The present invention relates to a non-toxic blind for automobile, and more particularly, it relates to a blend method for blending polyester yarn and LM (Low Melting) Despite the knitted fabric, there is no thermal deformation due to not being stretched, and a separate coating layer is formed to eliminate high-risk substances such as heavy metals, halogen compounds, phthalate compounds, and PVC, as well as odor and pollutants To a non-toxic blind for automobile having an antibacterial function capable of adsorbing and purifying odor, and a method for producing the blind.

Generally, a blind is a mechanism for blocking light entering the room from the outside or adjusting the amount of incoming light.

These blinds are made of various materials such as metal, wood, and fiber but they are not preferred for special purposes because they have no flexibility and rigidity in the case of metal or wood, and those made of fibers are mainly used.

Since such blinds are directly related to the textile industry, growth has slowed in line with the downturn in the textile industry. However, the blinds have recently become one of the new growth engines due to diversity, functionality, specialization,

However, blinds used in most multi-use facilities except for home use use flame retardant products due to legal obligations, but toxicities of flame retardant products are left in a blind spot in the law.

In recent years, thanks to the rapid economic growth, one household is moving beyond the age of one car to the age of one car.

Accordingly, in a vehicle having a narrow space characteristic, in particular, when light outside the summer is transmitted without filtration, the indoor temperature is increased, which increases the cooling operation rate, resulting in waste of fuel. On the contrary, blinds used in cold regions can not have blind inherent functions unless they are guaranteed to have a low-temperature bending property at a cryogenic temperature.

In addition, ultraviolet rays, visible rays, gamma rays, alpha rays, and beta rays that enter through the window act as harmful waves to passengers, and the unpleasantness caused by other various odors including the smell of cigarettes generated in the inside of the vehicle, It also acts as disgust.

As a means for preventing this, a variety of coating materials are disclosed and attached to the window of a vehicle, but it remains at a level that obscures the sunlight and is completely independent of the above-mentioned removal of harmful substances or deodorization.

Accordingly, in a number of patented technologies, including patent No. 0779954, patent No. 0744958, patent application No. 2009-0010307, and patent application No. 2013-0023240, an awnel that can cover a window of a vehicle or a sunshade, , Screens, and the like have been disclosed.

However, in most of these cases, only the function of shielding the sunlight is present. In recent years, flame retardant blinds with flame retarding function have been introduced, but the four heavy metals or volatile organic compounds It is threatening the health of passengers.

In recent years, advanced countries such as the United States and Europe have developed volatile organic compounds (VOCs), four heavy metal cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (Cr Ⅵ), and arsenic Cobalt, Nickel, Copper, Antimony and the like; Halogen compounds and other dangerous substances have been strengthened, but the domestic regulations have not recognized the seriousness of such regulations. Therefore, blinds applied to vehicles are also required to be improved.

In addition, the existing blinds for automobiles have a disadvantage that they are stretched when they receive heat, that is, they have elasticity, which causes severe deformation and short life span. In addition, in the cold winter season, the inherent flexibility of the fabric is deteriorated and the bending resistance of the fabric is very low.

The present invention has been made in view of the above-described problems in the prior art, and it is an object of the present invention to provide a knitted fabric which is not stretched due to a combination of heat treatment of polyester yarn and LM (low melting yarn) , Long life can be made, and a separate coating layer is formed to eliminate high-risk materials such as heavy metals, halogen compounds, phthalate compounds, and PVC as well as heat deformation, excellent cold resistance and cold bending resistance, The present invention also provides a novel non-toxic blind for automobile which has antibacterial and deodorizing function but is harmless to human body and its manufacturing method.

A non-toxic coating layer is formed on both side surfaces of a fabric constituting an automotive blind, wherein the non-toxic coating layer comprises water-soluble polyurethane resin in an amount of from 750 to 1000 wt. 15 to 25 parts by weight of a phosphorus flame retardant, 0.05 to 0.15 parts by weight of polyisobutylene, 0.01 to 0.02 parts by weight of a slipping agent, 0.1 to 0.5 parts by weight of a crosslinking agent, 0.05 to 0.15 parts by weight of a curing agent, 0.01 to 0.02 of dibutyltin dilaurate 0.3-0.7 parts by weight of an inorganic antibacterial agent, 0.3-0.7 parts by weight of an antifungal agent, and 0.05-0.07 parts by weight of a deodorant.

In this case, the yarn for weaving the fabric may be a mixture of carbon black polyester dyed yarn and low melting carbon black polyester dope yarn, Feature.

The mixed yarn is also characterized in that the LM yarn and the carbon black polyester yarn are piled in a weight ratio of 65:35 or 60:40 or 50:50.

In addition, the weaving method of the fabric is also characterized by a tricot method.

In addition, the present invention is characterized in that a mixed yarn in which a carbon black polyester dyed yarn and a low melting carbon black polyester dope yarn are twisted one by one is wewn in a tricot method, A weaving step of heat-treating at 180 占 폚 to suppress shrinkage and jamming of the fabric; A shrinkage refining step in which the woven fabric is placed in a steam dyeing bath and boiled at a temperature in the range of 113 DEG C to maintain the morphological stability of the fabric; A drying step of maintaining a total shrinkage ratio of about 10% so as to evaporate the moisture of the fabric shrunk in the refining process and at the same time to impart the inherent properties of the fabric and to make the fabric smoothness; When drying is completed, 750-1000 parts by weight of water, 15-25 parts by weight of a phosphorus-based flame retardant, 0.05-0.15 parts by weight of polyisobutylene, 0.01-0.02 parts by weight of a slip agent, 0.1-0.02 parts by weight of a crosslinking agent 0.1 , 0.05-0.15 parts by weight of a curing agent, 0.01-0.02 parts by weight of DBTDL (Dibutyltin dilaurate), 0.3-0.7 parts by weight of an inorganic antibacterial agent, 0.3-0.7 parts by weight of an antifungal agent and 0.05-0.07 parts by weight of a deodorant Forming a non-toxic coating layer on both sides of the fabric; And a tenter and a curing step of drying and curing the coating layer when the non-toxic coating layer is formed, and a curing step of fixing the coating layer to the non-toxic blind.

According to the present invention, it is possible to realize a mixed yarn which is not stretched or shrunk through a combination of heat treatment of polyester yarn and LM (low melting yarn) in spite of being a tricot type knitted fabric.

Further, it is possible to provide an automobile blind that is harmless to the human body because it is non-toxic, which does not generate heavy metals such as heavy metals, halogen compounds, phthalate compounds, PVC, etc., by further forming a separate coating layer.

In addition, there is no possibility of discoloration due to ultraviolet rays, durability and heat resistance are excellent, and there is no thermal deformation.

Furthermore, it has an excellent antimicrobial and deodorizing power, and has an odor eliminating function, so that it has an effect of keeping the interior of a car comfortable.

Hereinafter, preferred embodiments according to the present invention will be described in detail.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, the embodiment according to the concept of the present invention can make various changes and have various forms. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The non-toxic blind for automobile according to the present invention is formed by laminating nontoxic coating layers on the front and back surfaces of the fabric, respectively.

At this time, the fabric is formed by weaving, refining (boil off), drying and coating the yarn.

In this case, the yarn should be selected to have high tensile shrinkability in the case of the present invention, since they are exposed to strong light and heat for a long time.

Therefore, general polyester salt or salt salt method is unsuitable because it causes oxidization, aging, and sublimation of dyes, which causes problems when exposed to strong light and heat.

Therefore, high-tensile low-shrinkage polyester yarns are examples of the yarn capable of satisfying such a condition.

However, the yarn of the automotive blind according to the present invention should have a strength of at least 4.55 g / denier, an elongation of 30% or more and a non-shrinkage ratio of 7.2% or more.

For this purpose, in the present invention, it is required to be dyed with an inorganic pigment, particularly carbon black.

At this time, carbon black is used because carbon black has no discoloration or color fading even when exposed to light and heat for a long time.

In particular, in order to satisfy the above-mentioned properties, the filament yarn should have at least 75 Denier 24 filament yarn since it has excellent flexibility and physical chemical resistance.

Thus, the yarn that can be used in the present invention is a carbon black polyester dyed yarn.

However, in view of the sufficient tensile strength, tear strength, heat resistance and flex resistance, the carbon black polyester dyeing yarn is not used alone, but the low melting carbon (LM) Black Polyester Dope Dyed Yarn) is made by twisting one strand. In this case, LM yarn is a yarn produced by spinning a low-melting-point polymer into a sheath and a core, and can be easily fused between yarns by heat treatment at the time of processing, so that a coating or bonding effect can be obtained without special post-processing.

[Figure 1]

In this mixed yarn, the low melting point LM yarn of the two yarns is melted and melted and melted with another carbon black polyester dyeing yarn (Melting Point is 160 ° C higher than that of LM yarn) in the heat treatment process after weaving, The tensile strength, the tear strength, the heat resistance, the cold resistance and the like can be improved correspondingly.

In this case, the LM yarn and the carbon black polyester yarn should be mixed in a weight ratio of 65:35 or 60:40 or 50:50, since the LM yarn having a relatively low melting point must be maintained at least equal to the melting yarn If the content exceeds 65% by weight, the amount of LM company becomes relatively large, which may lead to characteristics that are vulnerable to heat. Therefore, the range should be limited to the above range.

In addition, although there are woven type plain weaving, twill weaving, runner weaving, etc., plain weave has the disadvantage that the yarn can not move freely due to many points of organization, that is, intersection points, It is difficult to adjust the aperture ratio because of its high density. Also, since it has a small texture point and is flexible, it has low friction fastness and is not suitable for a vehicle blind requiring durability.

Therefore, the present invention utilizes a tricot weaving method having high durability and excellent in friction resistance and mechanical properties.

The tricot structure is advantageous in that it can secure visibility, durability, and stability by arbitrarily adjusting the openess facter as well as enhancing the durability of the fabric by binding the oligo and the oligo with a net shape, that is, a knit structure.

In particular, durability and frictional resistance, which are characteristics of a fabric that can withstand repeated mechanical rubbing due to the nature of the product, should not be loosened or loosened, is also an important factor.

Tricot or knitting is excellent in shape stability, does not melt, has a slight stretch in the transverse direction, but is porous, so it has good breathability and breathability, is soft and has no wrinkles, There is an advantage not.

Here, a slight stretch in the transverse direction is not suitable for use in automobile blinds, so it needs to be supplemented.

This is because the tricot is woven in the form of a mesh by connecting the loops (nose, stitch) and loop in the vertical direction (tilting), that is, in the longitudinal direction, so that the tilting is performed by using the EFDS It is possible to reduce the stretchability in the transverse direction by making it perform the same function as the weft by sending it farther to the side.

For example, if weaving using the principle of weave pattern as described below, a durable texture can be obtained.

[Weave pattern]

[Enlarged view of the weaving state part]

In addition, when weaving through mixed yarn is completed, heat treatment is performed. Heat treatment reduces the size of weft and warp in the range of about 5% to make the fabric have shape stability in the production of finished product. For the purpose of minimizing the rate of so-called deformation when the finished product is manufactured and installed, the fabric is heat treated at a temperature of 160-180 ° C.

Then, as described above, as the LM yarn melts, the polyester yarn is completely wrapped and the elasticity of the polyester yarn is suppressed, so that even when heat is applied, thermal deformation does not occur and longevity can be achieved.

On the other hand, boil off refers to the use of various impurities such as grass or oil, spinning oil, sesame oil, and other impurities in the case of fabrics used in dyeing or processing coating processes. Such impurities, And it is necessary to remove it before coating of the dyeing process because it interferes to prevent uniform coating. This process is called refining.

The refining method can be a high pressure jigger or a jigger, usually in a steam dyeing tank at a temperature of about 113 ° C.

At this time, in order to prevent the fabric from being excessively shrunk, it is preferable to conduct the washing process in the bath about 2 times to induce contraction of up to about 7.8% on the warp.

Thereafter, the drying process is performed. In the drying process, the moisture of the fabric shrunk in the refining process is evaporated and at the same time, the inherent properties of the fabric are imparted to maintain the total shrinkage rate at about 10% So that coating can be performed well during coating.

Thus, when a selected yarn, such as a fabric woven with a mixture yarn, is prepared, a non-toxic coating layer is formed on both sides of the fabric, that is, on each of the front and back sides.

The non-toxic coating layer is provided in order to achieve more comfortable seating space by blocking harmful factors so as to ensure chemical stability in narrow space characteristics while meeting the EU REACH Oeko-Tex Standard 100 regulations.

Particularly, the non-toxic coating layer should have a durability that satisfies each country's automobile cycle test (CYCLE TEST) by eliminating the discharge of 4 heavy metals. Table 1 below shows the blind cycle test for Chrysler automobile Standard test method).

[Example of blind cycle test for Chrysler automobile] Environment cycle Environment (23, 50% relative humidity) 8,800 Cold (-29,0% relative humidity) 300 Warm (80, 0% relative humidity) 300 Open / Humidity (40,92% relative humidity) 2,600 Environment (23, 50% relative humidity) @ Various angles 30

[Cycle test by angle]

Also, it has high light resistance, but it should not have discoloration during UV exposure, and it can suppress the mold of pathogens such as mold and O-157 while adsorbing and removing sweat odor, tobacco odor, various odor and harmful substances generated in the indoor, And the like. That is, it has an antibacterial function.

In addition, the inclusion of phosphorus flame retardants makes it possible to comply with regulations on automobile materials and flame retardants in each country.

To this end, the non-toxic coating layer may contain 750-1000 parts by weight of water, 15-25 parts by weight of phosphorus-based flame retardant, 0.05-0.15 parts by weight of polyisobutylene, 0.01-0.02 parts by weight of slip, 0.1-0.5 parts by weight of a crosslinking agent, 0.05-0.15 parts by weight of a curing agent, 0.01-0.02 parts by weight of DBTDL (Dibutyltin dilaurate), 0.3-0.7 parts by weight of an inorganic antibacterial agent, 0.3-0.7 parts by weight of an antifungal agent and 0.05-0.07 parts by weight of a deodorant .

In the present invention, since volatile organic compounds (VOCs) should not be discharged from the blinds for automobiles, the substrate should be of a water-soluble type with no use of solvent. Examples of the water-soluble type resin include acryl or water- Acrylamide resin, polyamide resin, and modified epoxy resin.

However, the blinds for automobiles according to the present invention are required to satisfy the hydrolysis resistance, heat resistance, chemical resistance, flex resistance and scratch resistance, satisfy the EU REACH, Oeko-Tex Standard 100 and have chemical stability A more pleasant and safe chemical resistant resin or additive should be used from the harmful factor to be assured.

Thus, tin, isocyanate, formaldehyde, heavy metal catalyst systems. It is preferable to select a resin that does not contain a bromine compound, a halogen-based compound, or the like; In addition, it is preferable to select a highly durable resin that satisfies the flame retardancy test for blinds and the yellow test for each country.

Considering these various considerations, it is preferable to select PUD Resin (polyurethane dispersion) or Acryl Emulsion Resin which has various functions such as flexibility, frictional resistance, abrasion resistance, cold resistance and light resistance and is inexpensive.

Among them, it has high light resistance, it should be free from discoloration and deformation when it is exposed to UV for a long time, and it should be free from the discoloration and deformation of the blinds of each country (Korea: MS300-08, Japan: FMVSS NO.302, Klyler: ASTM39, GM standard specification: GM9070P, FORD: WSK -M4D647-A5, etc.) is most preferable.

Phosphorus flame retardant is not harmful to the human body because it has no black smoke when carbonized and it is extinguished together with weak white smoke and tends to have a somewhat weak heat resistance. However, phosphorus flame retardant is suitable for use in the present invention because it can withstand up to 180 ° C.

As flame retardants, blind flame retardancy standards of each country are satisfied, for example, Korea: MS300-08, Japan: FMVSS NO.302, Kleisler: ASTM39, GM standard specification: GM9070P, FORD: WSK-M4D647- There are no heavy metals such as cadmium, lead, mercury and hexavalent chromium, there is no halogen compound, and the EU REACH, Oeko-Tex Standard 100, Phosphorous flame retardants are most suitable as non-toxic flame retardants.

The phosphorus flame retardant should be added in an amount of 15-25 parts by weight. If it is less than 15 parts by weight, flame retardancy is lowered. If it exceeds 25 parts by weight, moldability is impaired.

Further, polyisobutylene is further added in the range of 0.05-0.15 parts by weight to increase the lubricity.

In addition, the slip agent is preferably a silicone to prevent contamination from various foreign matters at the surface of the surface. In this case, it is preferable to add 0.01-0.02 parts by weight of the slip agent.

The crosslinking agent is used for attaching a water-soluble polyurethane resin to a fabric, and one of tri- or higher-valent alcohol, tri- or higher valent amine or ethyl acetate derivative can be used, and a trace amount thereof is added in the above range.

In addition, the curing agent is used for solidifying the water-soluble polyurethane resin crosslinked to the fabric, and isocyanates or amines can be used, and a small amount of the isocyanate or amines is also added in the above range.

In order to shorten the curing time, known DBTDL (Dibutyltin dilaurate) is added. When the amount is excessively added, the curing is delayed. When a small amount is added, the curing is delayed.

In addition, the inorganic antimicrobial agent should be included together with antifungal property, and it is desirable that the air palm is also added together for reinforcement.

Since blinds for automobiles according to the present invention are exposed to Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae, Typhoid fungi, Vibrio fungus, Tochu fungi, ticks, fungi, yeast and O-157, Do.

For this purpose, the inorganic antibacterial agent is preferably one in which one of Ag, Cu, Zn and Ti is incorporated with Nano Silver, a photocatalyst, a water glass, a silacer system, a calcium phosphate system or a zeolite system.

In addition, the antifungal agent added together with the inorganic antibacterial agent may be one of butylbenzointiazoline, octylthiazoline, thiabendazole, and zinc chloride.

In addition, since deodorant is generated by various causative bacteria, it is not possible to deodorize all of them. However, deodorization function is given by oxidative decomposition method so that odor caused by organic matter, formaldehyde, ammonia and the like, .

For this purpose, one or more of sodium DL malate, zeolite and silica may be used in combination in the present invention.

Automotive blinds having such a non-toxic coating layer are manufactured as follows.

First, a weaving step is performed to produce a fabric that is a fabric.

The weaving step is a step of fabricating the fabric, which is a cloth material of a fabric, that is, a cloth for an automobile, by weaving the above-mentioned mixed yarn in a tricot method. In order to prevent the polyester yarn from being stretched by melting the LM yarn in the mixed yarn It must be accompanied by a heat treatment process in the range of 160-180 ° C.

When the weaving is completed in this way, the refining step is performed.

The refining step refers to boiling the fabric at a temperature of about 113 캜 by inserting the fabric into the steam dyeing tank, as described above.

When the refining step is completed, a drying step is performed.

The drying step is a step of maintaining the total shrinkage ratio at about 10% so as to evaporate the moisture of the fabric shrunk in the refining process and at the same time to impart the inherent properties of the fabric and to make the fabric smooth.

This is a process for smoothly coating the subsequent process, and removing the radial emulsion and other contaminants to increase the adhesion.

Upon completion of the drying step, a non-toxic coating layer forming step is then carried out.

The non-toxic coating layer forming step is a step of coating the above-mentioned coating liquid composition on both sides of the fabric and forming a coating film.

Since the non-toxic coating layer formed through the non-toxic coating layer forming step excludes the release of the four heavy metals, there is no harmful effect and adsorbs and decomposes various odors, thereby contributing to a more comfortable ride environment.

When the non-toxic coating layer is formed through the above steps, a tenter and a curing step for fixing the coating layer by drying, curing, and the like are performed.

In this case, the tenter stage is to dry the coating layer in the dryer of the tenter, and care must be taken when the drying is done incorrectly, because it may cause a lot of loss in flexibility, original activity, elasticity, etc.

In this case, the preferred drying method is hot-air drying, and it is particularly preferable to maintain the shrinkage ratio in the weft direction and the oblique direction at 3.5% during drying.

In this case, the temperature of hot air for each drying temperature is shown in Table 2.

chamber One 2 3 4 5 6 7 8 Temperature 90 ° C 100 ℃ 140 ° C 180 DEG C 220 ℃ 150 ℃ 120 DEG C 100 ℃ Hot air (rpm) 500 600 750 950 1000 950 700 500 function Vaporization exhaust exhaust heating heating fixation Shrink Hardening Width (mm) 146 148 150 152.4 154 150 148 147.8

In particular, the drying time is closely related to the curing, that is, curing. When the drying time is short, unhardened occurs to cause problems in adhesion and durability. On the contrary, when the drying time is long, Durability, lowering of bending resistance, lowering of fastness to rubbing, loss of preparation ability, and the like.

The curing step is performed at the same time as the drying step. In particular, the step of removing moisture remaining in the fiber more than necessary to cause a reaction between the resin and the fiber to effectively induce stable fixing.

After this step, the setting of the resin is completed and becomes the optimized state, and it becomes possible to manufacture a blind for a vehicle that achieves the object of the present invention.

Hereinafter, examples will be described.

At this time, since no toxicity is disclosed in the conventional product, it is only necessary to confirm whether the sample according to the present invention is non-toxic.

As a result of testing by SGS in order to confirm the non-toxicity of the sample, heavy metals such as Cd, Pb, Hg and Cr VI were not emitted at all as shown in Table 3 below.

This proved to be non-toxic.

Also, in order to confirm antifungal and antimicrobial properties, ASTM-G21 and KS M-0146 were tested as follows [Fig. 3] using mixed strains.

At this time, the medium used was NSGA Medium.

In addition, the test was conducted over a total of 4 weeks. Photographs were taken at weekly intervals, such as 1 week, 2 weeks, 3 weeks, and 4 weeks, as shown in [Figure 2].
