Description

Insect proof finishing and insect proofing carpet

The present invention relates to an insect repellent method and an insect repellent carpet which impart antibacterial and deodorant properties to a fibrous flooring material, that is, carpet, rug or mat, by using terpene extracted and purified from natural plants.

Most carpet insect repellents are toxic.

Representative agents used as insect repellents include Amitraz (WHO Class 3, EPA Class 3), Azocyclotin (WHO Class 2, EPA Class 2), Benzoximate (EPA 4) Grade), bromopropylate (WHO tertiary, EPA quaternary), clopentezine, fenazaquin, fenbutatin oxide, penpyroximate, Hexythiazox, Methylbromide, Milmemectin, Propargite (WHO Class 3, EPA Grade 1), Pyridaben, Tebufenpyrad (Brabufenpyrad) Toxicity, but most of them are harmful to humans as well as insects, and insect repellents such as camphor, naphthalene, parachlorobenzol and other highly sublimable chemicals produce unusual odors, making them unpleasant when storing or wearing textiles. Cause.

Recently, as consumers' interest in health has increased, interest in antibacterial and insect repellent, deodorant processing, etc. has increased, and a product having such a performance is required in the market.

Especially for residential carpets, mites have good conditions for breeding, and house dust mites are the most important cause of respiratory allergies.

When feces of these mites combine with immunoglobulin antibodies on the surface of the half-cells, histamine and other chemicals are secreted from the half-cells, causing bronchial hyperresponsiveness such as allergic rhinitis and allergic asthma and persistent respiratory allergy symptoms.

In particular, most of atopic dermatitis in children is caused by mites.

As a functional product that deodorizes a conventional fiber, a graft processing method of vinyl monomer having an acid group in the fiber (Japanese Patent Publication No. 3-77308, etc.) and a method of attaching the compound or various deodorants to the fiber surface are known (Japan). Japanese Patent Application Laid-Open No. 61-231202).

Among the above methods, the method of grafting on the fiber has a disadvantage of roughly changing the feel of the fiber, and also causes a pollution problem due to waste water.

In addition, the method of attaching various deodorants to the fiber surface has a problem that not only lowers the touch but also wash durability due to the process of attaching the fine powder of these materials.

The present invention uses a terpene extracted from a natural plant instead of a toxic insect repellent harmful to the human body to prevent pests such as ticks and parasitic mites, and at the same time have an antibacterial and deodorant insect repellent method and insect repellent There are technical challenges in providing carpet.

In order to solve the above problems, the present inventors have studied various natural-derived substances that are considered to have little environmental pollution and have no adverse effects on the human body. As a result, terpene, which is a main component of essential oils of low molecular weight plants, has insect repellent properties. It was found that the present invention was completed.

The present invention relates to a good laundry durable insect repellent processing method and insect repellent carpets by selectively attaching a terpene, a natural substance, to the bubble surface of the carpet or the surface layer of the pile yarn using a binder, or both.

The terpene used in the present invention also has the effect of removing odors by chemically reacting with nonpolar malodorous molecules and ionizing gaseous malodors. When the insecticide of the present invention is treated to a carpet, deodorization and deodorization to purify the odorous components of indoor air The effect can be expected, and according to the type of terpene, the aroma effect by the scent of various herbs derived from the terpene can be expected, as well as the antibacterial effect, which is a unique property of the terpene.

In addition, the fragrance of the terpene can be expected to treat the mental and physical diseases called aromatherapy.

The mono terpene used in the present invention is a compound having a composition of 10 carbons and 16 hydrogens (C10H16), which can be obtained from extracts of natural products.

Examples of natural extracts include peppermint oil, cinnamon oil, spearmint oil, lemon oil, citron oil, lime oil, grapefruit oil, sandalwood oil, laurel oil, pine oil, ginger oil, rosemary oil, and the like. Terpenes can be extracted from the ingredients.

In addition, the terpene component purified from the natural oil as a single component is di-limonene, α-farnesene, β-selinene, β-selinene, camphene and gerani. Geraniol, menthol, α-, β-pinene, terpineol, γ-terpinene, β-elemene, farnesene, β- Myrcene (myrcene), (alpha) -terpinolene, etc. are known.

D among the components - Limonene is known to be greater the room loyalty and antimicrobial among terpenes, Aspergillus way been found that the growth and the effect of suppressing the generation of the aflatoxin (aflatoxin) Russ para City kusu (Aspergillus parasiticus), It is known to exhibit antimicrobial activity against bacteria such as fungi, such as Colltotrichum falcatum, Fusarium moniliforme, and Ceratocystis paradoxa. It is also known to have powerful insecticidal properties such as ants, ticks and cockroaches.

In this invention, such a terpene component shall contain the structurally identical compound synthesize | combined by chemical synthesis.

As a method for imparting anti-mite property to a carpet, a method of using a bubble having insect repellency in the foam of the carpet, a method of containing an insect repellent in a latex used for carpet backing or the like is mainly used.

In addition, there is a method of incorporating the insect repellent into the yarn constituting the carpet, and there is also a method of imposing and fixing the insect repellent on the surface of the carpet by dipping, dipping, or spraying after producing the carpet.

Terpenes, which are insect repellents used in the present invention, cannot be attached to fibers, and therefore binders are used.

As the binder, a natural binder, a derivative thereof, a synthetic binder, or a mixture thereof is used.

Most binders are water-soluble, but terpenes are hydrophobic, so insect repellents or dispersants are added for mixing binders and terpenes.

The emulsifiers and dispersants used herein are those having an emulsifying power in the range of 9 to 17, regardless of the type of surfactant such as anionic, nonionic or amphoteric, as surfactants.

Terpene in the present invention is preferably used 1 to 20% by weight based on the weight of the binder.

If it is less than 1% by weight, the desired effect of the present invention cannot be expected, and if it exceeds 20% by weight, it is easy to cause phase separation with the resin, coating is difficult and the price is high, so it is not economical and the touch is also bad.

In the present invention, the insect repellent treatment agent composed of a terpene, a binder and an emulsifier and a dispersant is coated on the foam of the carpet by a general dry coating method or a wet coating method.

When coating, the thickness is about 0.02 ~ 0.5mm is suitable, but if necessary, a thick coating may be used.

In addition, in the present invention, the insecticide may be used by dipping and spraying in addition to the coating method.

In addition, the insect repellent carpet of the present invention, after tufting the fibers such as nylon, PTT, PET, wool, cotton, PP to the foam coated with the insect repellent agent (back-coating) with isoprene rubber, etc. To prepare.

Insect repellent carpet of the present invention can also be produced by impregnating or spraying the insect repellent agent to the pile yarn made of fibers such as nylon, PTT, PET, wool, cotton, PP.

The insect repellent adhering to the surface of the pile yarn is dried and cured through heat treatment to be made of durable insect repellent pile yarn.

The present invention can be applied to fibrous flooring materials such as rugs, tile carpets, and carpets in addition to carpets.
