Description

{NON-TOXIC BLACKOUT BLIND}

The present invention relates to a non-toxic black-and-white blind, and more particularly to a non-toxic black-and-white blind that is free of high-risk materials such as heavy metals, halogen compounds, phthalate compounds and PVC.

The blinds are devices that block light entering the room from outside or adjust the amount of incoming light to be lower.

These blind blinds are made of various materials such as metal, wood, and fiber. However, in the case of metal or wood, they are not flexible and have a high rigidity, so they are not preferred except for special purposes.

Since such blinds are directly related to the textile industry, the growth has slowed due to the decline of the textile industry. Recently, blinds have become one of the new growth engines by diversity, functionality, specialization, .

In this connection, as prior arts of the black-and-white blind, there have been disclosed many of the registered patents No. 0349174, No. 1025303, No. 0736437, and No. 2010-0007981.

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, most of them have been converted to flame retardant products regardless of whether they are used for home use or office use. Despite the fact that regulations on toxic substances have been strengthened or mandated globally, domestic efforts to regulate toxic substances There are few.

For example, the European Union (EU), which entered into force on 1 June 2007, is a new chemical management system of the European Union (EU) The European Union has enacted a system that integrates about 40 chemical substances related laws in the EU and enforces the registration of chemical substances manufactured or imported more than 1 ton per year.

In addition, since the mid-1990s, we have started to regulate the use of eco-labels for textile products, and 10 years later, in July 2006, we enacted RoHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (SVHC), which is applicable to all industries, and is obliged to be restricted.

In addition, the United States introduced the Green Guard system at similar times in the EU, including Volatile Organic Compound (VOC), cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium Arsenic, Cobalt, Nickel, Copper, Antimony and the like; Halogen compounds and other dangerous substances have been regulated.

However, in Korea, it is not recognized the seriousness of the above problems.

A base layer, a medium layer, and a skin layer are sequentially formed on both sides of a fabric constituting the black blind, wherein the base layer is formed of a water-soluble polyurethane resin, 30 to 50 parts by weight of R type titanium dioxide, 5 to 15 parts by weight of water, 60 to 80 parts by weight of a phosphorus flame retardant, 15 to 25 parts by weight of MC (melamine cyanate), 0.1 parts by weight of a dispersant, 0.3 to 0.7 parts by weight of an antifungal agent, 0.05 parts by weight of a deodorant, 0.01 parts by weight of an antistatic agent, 0.1-0.5 parts by weight of a crosslinking agent and 0.05-0.15 parts by weight of a curing agent; The medium layer is composed of 100-120 parts by weight of R-type titanium dioxide, 10-16 parts by weight of water, 7-11 parts by weight of buthyl cellosolve (BC), 15-25 parts by weight of phosphorus 15 to 25 parts by weight of MC (melamine cyanate), 0.3 to 0.7 parts by weight of a dispersant, 0.25 parts by weight of an inorganic antibacterial agent, 0.25 parts by weight of an antifungal agent, and 0.05 parts by weight of a deodorant; Wherein the skin layer comprises 100-120 parts by weight of R-type titanium dioxide, 10-16 parts by weight of water, 7-11 parts by weight of buthyl cellosolve, 15-25 parts by weight of a phosphorus-based flame retardant, 0.3 to 0.7 parts by weight of an antifungal agent, 0.3 to 0.7 part by weight of a deodorant, 0.01 part by weight of an antistatic agent, and 10 to 20 parts by weight of a pigment (pigment), 0.5 parts by weight of a dispersant, 0.01 parts by weight of a slip agent, 0.3-0.7 parts by weight of an inorganic antibacterial agent, The present invention also provides a non-toxic black-and-white blind.

At this time, the yarn for weaving the fabric is polyester, and the weaving method is also a plain weave.

Further, at the time of weaving, the warp yarns use 150denier-48filer or 300denier-96filer; The company uses 150denier-48filer or 300denier-96filer or 450denier-144filer or 600denier-192filer; The density is 90 to 98 T in the case of 150 d, 35 to 50 T in weft; In the case of 300d, the warp is 85 to 95T and the weft is 38 to 50T.

The fabric is also characterized in that it is immersed in boiling water or subjected to steam at a temperature in the range of 120 ° C to be refined in advance at a constant rate.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a black blind which is harmless to the human body because it is non-toxic and does not generate a harmful substance such as heavy metals, halogen compounds, phthalate compounds, PVC and the like.

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

In addition, it has excellent antimicrobial and deodorizing power, antistatic function, and excellent black performance because it satisfies 99.99% of black out degrees.

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 black blind according to the present invention is formed by sequentially laminating a base layer, a medium layer and a skin layer on a front surface and a back surface of a fabric, respectively.

At this time, the black blind is formed by weaving, refining (Boil off), drying and coating the yarn.

In this case, there are various kinds of yarns selected in the weaving process besides acrylic yarn, nylon yarn, cotton yarn, viscose yarn / nylon blend yarn / polyester blend yarn, wool yarn, silk yarn, polyester yarn, Weaving in various shapes such as woven, knitted, woven, twilled, and jacquard.

However, in order to satisfy the stability, tensile strength, tear strength, heat shrinkage, abrasion resistance and cold warp of the product, the black film blind related to the present invention uses a polyester high strength water storage housing having high mechanical friction strength, Is particularly preferable.

Here, the types of high-tensile low-shrink yarns deal with yarns of different kinds according to yarn makers, but there are various kinds of yarns according to purposes such as UDY, POY, DSD, NPY, ITY, ATY, DTY.

The choice of yarn should be excellent in light fastness, stabilized by light or heat, less deformed during the summer or winter, less wrinkle and less stretch.

In addition, there should be no damage to chemicals, insects, bacteria, etc., and it should be resistant to acids, alkalis, organic solvents, and the like, have good dry cleaning resistance, and be accompanied by conditions that impurities and dioxins should not be released when carbonized.

Therefore, acrylic yarn and polyester yarn can be cited as the yarn satisfying these conditions. Among them, it is particularly preferable to use polyester yarn in consideration of price, function, thermal stability, cold resistance and the like.

For example, acrylic yarn is excellent in affinity to acid dyes, basic dyes, chrome dyes and catch dyes, and has excellent water fastness and light fastness, and has excellent friction durability, so that wrinkles are not easily generated. However, water content is 1-2% It is similar to cotton and rayon but has a disadvantage that it is rapidly decomposed into strong alkaline.

In addition, the polyester yarn is stronger than the nylon when it is pulled, and its strength when wetted with water does not change. Especially, the wrinkle recovery is similar to that of wool, and the degree of recovery when wetted High strength, little stretchability, and very high dryness, which is advantageous in durability; There is a disadvantage of static electricity and bopp because of low hygroscopicity.

In addition, the weaving method is general plain weaving, which is the most basic structure that alternates between warp and weft. It is also referred to as Oxford (Oxford) organization, and has the most intersection points and hard texture.

At this time, it is preferable to use a 150 denier 48 filer and a 300 denier 96 filer.

The use of 150 denier 48filer, 300 denier 96filer, 450 denier 144filer, and 600 denier 192filer is preferable in terms of tensile strength shape stability, dimensional stability, and shrinkage stability.

And, in the case of density, 150d is inclined 90 to 98T, weft 35 to 50T; 300d is the most stable with 85 ~ 95T inclination and 38 ~ 50T weft.

In this case, when the density is lower than the above range, a twist phenomenon occurs. When the density is higher than the above range, the defect rate is high at the time of weaving, and the adhesive strength is decreased during coating, It should be limited to the above range.

In addition, boil off refers to the use of various impurities such as grass or oil, spinning emulsion, silicone emulsion, and other impurities in the case of fabrics used in dyeing or processing coating processes. Such impurities may include dyes and coatings 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. After the impurities are washed at a high temperature and a high pressure of 110 ° C or higher, heat setting and shrinkage processing is performed to a range of about 5% In order to minimize the ratio of so-called deforming when the finished product is manufactured and installed after it is manufactured and manufactured.

Thus, when a selected yarn, such as a fabric woven with polyester yarn, is prepared, a base layer is formed on both sides of the fabric, that is, on each of the front and back sides.

The base layer is a layer formed for the purpose of enhancing the durability of the product and improving the hiding power, and is preferably designed so as to have a soft texture and abundant elasticity.

In this case, the durability corresponds to the adhesive strength and the anti-loosening property, and the hiding power means that the flame retardancy of 95% or more and the blackout degrees of 99.99% are satisfied.

To this end, the base layer is composed of 30 to 50 parts by weight of R-type titanium dioxide, 5 to 15 parts by weight of water, 60 to 80 parts by weight of phosphorus-based flame retardant, MC (melamine cyanate) 15 -25 parts by weight, a dispersant 0.1 part by weight, an inorganic antibacterial agent 0.3-0.7 parts by weight, an antifungal agent 0.3-0.7 parts by weight, a deodorant 0.05 part by weight, an antistatic agent 0.01 part by weight, a crosslinking agent 0.1-0.5 part by weight, ≪ / RTI >

In the present invention, the VOC (volatile organic compound) should not be discharged from the black blind. Therefore, the base material should not be used as a solvent but should be of a water-soluble type. As the water-soluble type resin, acrylic or water-soluble urethane resin, Amide resins, polyamide resins, and modified epoxy resins.

However, the black blind according to the present invention is required to satisfy the hydrolysis resistance, heat resistance, chemical resistance, flex resistance and scratch resistance, satisfies EU REACH, Oeko-Tex Standard 100, A more pleasant and safe chemical resistant resin or additive should be used.

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 is required to have high light resistance, to be free from discoloration and deformation when exposed to UV for a long time, and to be used in various blind flame retarding regulations (Korea: KS K ISO 15025 / KS K 0585 USA: NFPA 701, UK: BS5867 France: NF P 92-507 ) Is most preferable.

When R is added at less than 30 parts by weight, the whiteness is lowered, and the light shielding ratio and the ultraviolet light blocking ratio are lowered, and more than 60 parts by weight The physical properties will deteriorate.

In addition, the phosphorus flame retardant has the advantage of being harmless to the human body because it has no black smoke upon carbonization and is extinguished together with weak white smoke, and tends to have a somewhat weak heat resistance, but is sufficient to be used in the present invention because it can withstand up to 180 ° C.

In this case, as the flame retardant, blind flame retardancy standards of each country are satisfied, for example, KS K ISO 15025 / KS K 0585 USA: NFPA 701, UK: BS5867 France: NF P 92-507 (M1) But there are no heavy metal emissions such as cadmium, lead, mercury and hexavalent chromium, there is no halogen compound, and it is possible to meet EU REACH and Oeko-Tex Standard 100 As a non-toxic flame retardant, phosphorus flame retardant is most suitable.

The phosphorus flame retardant should be added in an amount of 60 to 80 parts by weight. If the phosphorus flame retardant is less than 60 parts by weight, the flame retardancy is lowered. If it exceeds 80 parts by weight, moldability is impaired.

In addition, MC (melamine cyanate) is added to reinforce the weak heat resistance of the phosphorus flame retardant.

The MC should be added in an amount of 15-25 parts by weight, and if it is added in an amount of less than 15 parts by weight, the phosphorus-based flame retardant may have insufficient heat resistance. If the amount exceeds 25 parts by weight, the curing property is rapidly increased.

The dispersing agent should be a non-silicone dispersing agent having good compatibility with the water-soluble polyurethane resin.

In addition, inorganic antimicrobial agents should be included together with anti-fungal agents, and it is desirable to add air fungicides for reinforcement.

The dark blinds according to the present invention are exposed to Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae, Typhoid fungus, Vibrio fungus, Tochoma fungus, etc., ticks, fungi, yeast and the like.

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.

Since deodorant is generated by various causative bacteria, it is not possible to deodorize all of them. However, deodorizing function is provided by oxidative decomposition method so as to surely catch the deodorizing function of odor caused by organic matter, formaldehyde and ammonia .

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

In addition, the antistatic agent is for suppressing the generation of static electricity, and may be added by selecting at least one of stearyldimethylbenzylammonium chloride, cetyltrimethylammonium chloride, bis (acryloxyethyl) hydroxyethylmethylammonium methylsulfate .

Further, the crosslinking agent is used for promoting the crosslinking action of the additive, and one of trihydric or higher alcohol, trivalent or more amine, and ethyl acetate derivative can be used.

In addition, the curing agent is used for solidifying the additive, and isocyanates or amines can be used.

On the other hand, the medium layer is a layer formed on the upper surface of the base layer. It is a layer which is formed by applying flame retardancy, strengthening the dark coat, strengthening the hiding power and enhancing whiteness, .

Such a medium layer is composed of 100-120 parts by weight of R-type titanium dioxide, 10-16 parts by weight of water, 7-11 parts by weight of BC (buthyl cellosolve), 15-25 parts by weight of phosphorus 15 to 25 parts by weight of MC (melamine cyanate), 0.3 to 0.7 parts by weight of a dispersant, 0.25 parts by weight of an inorganic antibacterial agent, 0.25 parts by weight of an antifungal agent and 0.05 parts by weight of a deodorant.

At this time, the components overlapping with the base layer are added for the same reason, but they differ only in the characteristics in terms of the content.

And B.C (Buthyl cellosolve) is a solvent, and if it is added in an excessive amount, the adhesive strength with the base layer is lowered, and when it is added in a small amount, the lubricity is lowered.

In addition, phosphorus is contained in fibers, i.e., fabrics, and contributes to enhancing flame retardancy, i.e., flame retardancy, by ultraviolet curing.

In the medium layer of the present invention, it is added in place of the phosphorus-based flame retardant used in the base layer. When the amount is more than 25 parts by weight, the activity is increased, and when it is less than 15 parts by weight, flame retardancy is deteriorated.

On the other hand, the skin layer constitutes a surface layer and is a layer configured to have scratch resistance and a beautiful appearance.

Such a skin layer should have a friction fastness, chemical resistance, flame retardancy, and physical stability when forming the surface.

In addition, the composition ratio must be determined in consideration of the durability by increasing the adhesion with the medium layer as the secondary coating surface.

In this case, the same components utilized in the other layers described above are added for the same reason, so the functions are the same only in the contents.

Such a skin layer may contain 100-120 parts by weight of R-type titanium dioxide, 10-16 parts by weight of water, 7-11 parts by weight of buthyl cellosolve, 15-25 parts by weight of a phosphorus flame retardant, 0.3 to 0.7 parts by weight of an antifungal agent, 0.3 to 0.7 parts by weight of a deodorant, 0.01 parts by weight of an antistatic agent, 10 to 20 parts by weight of a pigment (pigment), 0.5 parts by weight of a dispersant, 0.01 parts by weight of a slip agent, Part.

In this case, the slip agent is used to prevent contamination from various foreign substances on the surface. Silicon is preferable, and further includes an antistatic agent to prevent static electricity due to electrical friction of the surface. In consideration of light resistance, durability and UV stability, Pigment should be used.

The block blind having such a layered structure can be produced according to a known manufacturing method as shown in the above-described prior arts.

Hereinafter, examples will be described.

[Example]

In order to confirm the characteristics of the non-toxic black blind according to the present invention, a sample (Sample No. AYSA14-08386.001) having a base layer, a medium layer and a skin layer having the composition ranges described above was prepared and then it was confirmed that it was non-toxic.

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.

However, the melamine cyanate, butyl cellosol part and the like in each layer composition of the present invention were inferior to the above-mentioned samples in terms of discoloration resistance, heat stability, lubricity and slipperiness when they were out of the above-mentioned categories.

As a result of testing by SGS in order to confirm the non-toxicity of the sample, heavy metals such as cadmium (Cd), lead (Pb), mercury (Hg) and hexavalent chromium (Cr Ⅵ) And no halogen-based material was also detected.

This proved to be non-toxic.

In order to confirm antifungal and antimicrobial properties, ASTM-G21 and KS M-0146 were tested as follows [Figure 1] 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 1].

[Figure 1]

As shown in [Figure 1], the test samples of the present invention showed no fungus habit and no growth of other strains.

Through this, it was confirmed that there was antifungal and antibacterial activity.

Accordingly, the black blind according to the present invention is a non-toxic product, and has excellent antimicrobial and antifungal properties. Thus, it is possible to produce a flame retardant product that satisfies the standards of each country by including a phosphorus flame retardant.
