Description

Carrier dyeing method for PTT fiber by using the natural terpene and PTT fiber poduced by the said method}

The present invention relates to a low-temperature dyeing method of PTT (polytrimethylene terephthalate) fibers using a carrier of terpenes and the PTT fibers thereof.

Carriers have been used for low temperature dyeing, stain prevention, and refining of polyester and nylon fibers in the past.

In particular, when dyeing a blend of polyester fibers and other fibers, the carrier has been used to prevent other fiber components, such as wool and silk, when the temperature is raised to around 130 ° C, which is a dyeing temperature of the polyester.

In other words, in order to prevent embrittlement of protein fibers or cellulose fibers that are easily embrittled at high temperatures, dyeing at 100 to 105 ° C. makes it difficult to obtain concentrated salts of polyester fibers. Has been used.

In recent years, PTT fibers with superior antifouling properties, elongation, and dyeing properties have been developed, but these PTT fibers exhibit sufficient color concentrations due to their insufficient dyeing at 100 ° C or below. In order to bet, use of a carrier is inevitable.

However, the conventional carrier is mainly composed of phenylphenol, diphenyl, methylnaphthalene, dichlorobenzene, trichlorobenzene and the like, and these compounds are harmful to the human body, cause odor during work, and have environmental problems such as environmental pollution. Use is being avoided.

An object of the present invention is to provide a salt method of PTT fiber and a dyeing method of PTT fiber using a carrier of a natural terpene component instead of the conventional carrier which is less polluted to the environment, has no odor, and is capable of thick dyeing at low temperatures. It is done.

In order to solve the above problems, the present inventors have studied various natural-derived substances that are considered to have little environmental pollution, no odor, and no adverse effects on the human body, and have found that low molecular weight natural vegetable oils are effective as carriers. The present invention has been completed by finding that terpene, which is a main component of low molecular weight plant essential oil, is an effective ingredient as a carrier.

Terpenes derived from natural substances are compounds having a composition of 10 carbons and 16 hydrogens (H10C16), and are mainly contained in essential oils of pine trees (pine, clove, cypress, etc.). The antimicrobial and anti-inflammatory effects have been studied by many experts, and more than 400 types have been identified. The well-known anticancer drug Taxol is also an alkalide derivative of terpene.

In addition, Pinnen, Campen, Cineol, Fencon, Borneol, Anetol, thymen, chamazulene, etc. are commercially available.

In addition, terpenes have the effect of removing odors by chemically reacting with nonpolar malodorous molecules and ionizing gaseous malodors, so there is no fear of malodors when carrier-dyed with terpenes.

Methane-type monoterpenes having a monocyclic structure as a carrier of the terpene component derived from the natural substance are menthane and menthene represented by Chemical Formulas 1 to 3 below. ) And the form of menthadiene derivatives.

Methane (monocyclic) having a monocyclic structure is another form of the cyclohexane (cyclohexane) of the form of the formula (4-6), which is classified as tetramethyl-cyclohexane type (Tetramethyl-cyclohexane type) Hexane (cyclohexene) and cyclohexadiene derivatives.

Monoterpenes (monoterpene) and dicyclic terpene terpene is a compound characterized by having the structure shown in the following formula (7).

(Formula 7) (Formula 8) (Formula 9)

Among the terpenes, diterpenes and cyclic diterpenes are in the form of a combination of four molecules of 2-methyl-1, 3-butadiene (2-methyl-1, 3-butadiene). Vitamin A belongs to this.

The monoterpenes and diterpenes are found as extracts of natural products.

Examples of natural extracts include peppermint oil, cinnamon oil, sparemint oil, lemon oil, citron oil, lime oil, grapefruit oil, sandalwood oil, laurel oil, pine oil, ginger oil, rosemary oil, and the like. can do.

In addition, terpene components purified from natural oil as a single component include S-, T-, D-limonene, α-farnesene, α-farnesene, β-selinene, and camphene. ), Geraniol, germentol, menthol, α-, β-pinene, terpineol and the like are known.

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

Since the terpene is a lipophilic substance, derivatives that make the lipophilic terpenes water-soluble include derivatives modified in the form of metal salts or modified in the form of alcohols, and the like. It is useful for imparting an effect of increasing solubility.

In order to emulsify, disperse, and dissolve terpene in water, a carrier mixed with a surfactant such as a dispersant and an emulsifier is used. The thing which has an emulsification power in the range of 9-17 is used, and the thing of the range of 10-14 is good.

The dyeing method using the carrier can be applied in the salt method including all raw salts, salts, and flames, and disperse the PTT regardless of the method of batch dyeing, continuous dyeing, printing, jet printing, or the like. Including all methods to dye.

In particular, the contact time between the chlorine and the heat medium is more effective in the continuous dyeing and printing method than the batch dyeing.

PTT fibers that can be dyed using the carrier of the present invention include not only PTT 100%, but also composite fibers of PTT fibers such as PTT / nylon, PTT / cotton, PTT / hair, PTT / PET and other fibers, and also It can be used for various tissue materials such as yarn, woven fabric, knitted fabric, carpet, and nonwoven fabric.

Also included are PTT fibers containing titanium dioxide (TiO ₂ ) used to increase the opacity of PTT yarns.

The purpose of using titanium dioxide is to reduce the glossiness of the product, and usually contains a titanium dioxide in the range of 0.1 to 2.0% by weight.

When the dyeing method using the carrier of this invention is demonstrated, it adds to a salt bath so that it may be 1 to 20 weight% with respect to a to-dyed fiber, and 2 to 8 weight% is preferable.

It may be dyed after treating the salts in a carrier bath in advance.

The dye used to dye the PTT fiber is a disperse dye, and in the case of low temperature dyeing pursued by the present invention, it is preferable to use a disperse dye of low energy type.

In the case of a composite fiber, it is possible to use a dye suitable for each fiber (for example, nylon is an acid dye, cotton is directly or a reaction dye, etc.).

When dyeing PTT fibers, it is also possible to use a dispersing or leveling agent used to improve dispersibility and leveling properties.

In this case, the amount of 0.5 to 3.0 g / l is added to the dyeing bath, and the bathing ratio of dyeing is generally performed between 1: 5 to 1:50. To increase polyacrylic acid, cellulose derivatives, alginic acid derivatives, modified starches and the like are used.

At this time, the pick-up rate of the salt solution to the salt solution is generally 100 to 800%, and this ratio is 300 to 500% during continuous dyeing of general carpets.

Dyeing temperature is possible at 80-120 ℃, preferred is 98-103 ℃, and dyeing time is 20-40 minutes for light color, 40-60 minutes for medium color, 60-80 minutes for deep color. And fastness.

Since PTT has a lower glass transition temperature than the conventional polyester fiber, sufficient thick salt is possible under the above conditions, and when the carrier of the present invention is used, sufficient deep color expression is possible even at 80 to 95 ° C.

As can be seen from the results of Table 2, when the PTT carpet is dyed at a low temperature (100 ° C.) under a normal pressure using a carrier derived from natural environment, there is little environmental pollution and does not generate steam and odor that adversely affects health, and high temperature. It is possible to achieve the deep color staining that can be obtained when dyeing at room temperature in the presence of a high pressure or a general carrier. Especially, when di-limonene is used as a carrier, the color can be almost the same as that of a general carrier. It can be seen that it does not affect anything.

The present invention not only enables carrier staining, which is less harmful to the environment, harmless to the human body, and less likely to cause odor, but also enables dyeing without any damage to the fastness and thickening effect in comparison with conventional synthetic carriers.
