Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polypropylene yarn capable of improving the warp and post dyeability of polypropylene fibers,

The present invention relates to a process for producing polypropylene yarns which can improve the warp and post dyeability of polypropylene fibers.

Polypropylene fibers were called "dream fiber" and "last fiber" at the time of emergence and attracted great interest from around the world. By-products that are generated in large quantities during refining of petroleum are called "dream fibers" in that propylene is polymerized to make polypropylene, which is light and strong enough to float on water. At that time, it was called "The Last Fibers" because it could not be made any more.

Polypropylene fibers are melt spinning like polyester fibers, and they are fiberized by hot rolling. Staple, multifilament, and monofilament are produced industrially. Polypropylene fiber has a specific gravity of 0.91, less than water, and is the lightest and whitest among natural and synthetic fibers. In addition, it has the advantage of high strength and excellent chemical resistance. In addition, it has high abrasion resistance and excellent elastic properties. As such, it was a breakthrough in terms of manufacturing process and performance, but it is not desirable as a clothing material, and the demand therefor is extremely small and its use is extremely limited. This is because such clothes have poor dyeability, weatherability, and heat resistance, which are not suited to the various performances required for a garment material.

Polypropylene fibers are generally adopted as new materials for clothing due to various functionalities such as environmental friendliness, light weight, and stretchability of polypropylene fibers. In recent years, polypropylene Improved polypropylene fiber that complements the disadvantages of fiber has been developed and is expanding its use as an outdoor material.

Particularly, in the case of the EU, since 2005, as a material for home interiors such as wallpaper, partitions, etc. due to the environmental friendliness of polypropylene fiber, there has been a bill for the use of polypropylene fiber Development is becoming common. In addition, polypropylene fibers are becoming an essential material when it comes to expanding the market to developed markets.

While maximizing the advantages of polypropylene fiber, it is possible to make a stepping stone to present a new vision to textile companies if the disadvantages of polypropylene fiber are improved by mixing or cross-processing with existing synthetic fiber materials. It is forecast.

Of polypropylene fiber  Characteristic

1) Quick-drying material.

The moisture absorption rate of polypropylene fiber is extremely low at 0.05% which is almost ZERO. Therefore, when polypropylene fiber is used for clothing, it has a property of discharging it directly out of the fiber without containing sweat and moisture generated in the human body.

The surface is highly hygroscopic and is considered to be a suitable material for undergarments and socks. However, it is hygroscopic, but since it does not emit at all, it gives a moist feeling and has problems such as odor and mold.

Polypropylene is considered to be a very promising material as a sweat-absorbent quick-drying material because it exhibits excellent characteristics of wicking that moisture is rapidly evaporated through a fiber structure and air is contained intrinsically in a fiber structure.

The sweat-absorbing, quick-drying raw material of which the material raw material is polyester is inevitably containing a certain amount of moisture due to the nature of the raw material, so that even if the water output is excellent, moisture still remains in the fiber while the polypropylene fiber has no residual moisture. I will exert.

2) It is an antibacterial material.

Because it does not absorb moisture, it has antibacterial function by itself because there is no germ generation factor itself. Therefore, applications are being developed for outer covers of baby diapers, women's sanitary napkins and women's sanitary napkins, It is certified harmless fiber of human body.

3) It is eco-friendly material.

Polypropylene fiber composition Because the molecular structure is composed only of C and H, there is no deterioration of polymer performance during recycling and no toxic gas is emitted when incinerated. In the market of developed countries where environmental problems are important, And has expanded its use as a material.

The energy consumption in the production process is the smallest, and when the regeneration is carried out, the melting point is low and it can be easily re-dissolved.

4) It provides comfortable fit without static electricity.

The relative dielectric constant of the polyester fiber is 3.2, while the relative dielectric constant of the polypropylene fiber is 2.2, which is low enough to generate static electricity, thus providing a comfortable fit.

5) Excellent chemical resistance and no damage to insects or mites.

It is particularly strong against strong chemicals such as strong acids and strong alkali, and it does not cause damage to insects or mosses. It is excellent in chemical resistance and does not discolor even when it comes into contact with chlorine.

6) It has a specific gravity of 0.91 and is light enough to float on the water.

Although the price of yarn per unit weight is high, considering the specific gravity of 1.36 and the specific gravity of 0.91 of polypropylene fiber, 50% more output can be obtained from the same raw material.

7) Excellent warmth.

Polypropylene fibers are suitable for underwear because they are warm because they have low thermal conductivity.

8) High resistance to polar contaminants.

Polypropylene fibers are very resistant to polar contaminants, which are important properties for carpets and furniture applications due to their polarity because the constituent molecules are composed only of hydrocarbons.

9) Dyeability is not very good.

Due to the difficulty of post-dyeing due to the non-polar structure of the polypropylene fibers and the dense structure of the molecular structure having a high crystal area of 2/3 or more, the primary yarn occupies the majority of the polypropylene fibers, There is a limit to the use of

10) Melting point is somewhat low.

Although the melting point is somewhat low (165 ° C), it is reasonably high enough to be used in many applications.

It can be easily fused to other synthetic fibers and is suitable for producing meltblown nonwoven fabric.

11) The daylight fastness is not good.

Polypropylene fiber itself does not have good light fastness, but since it has compatibility with heat stabilizer and UV stabilizer, it is used for special purpose because it has a light fastness that is difficult to reach with dyeing.

Comparison of properties of main synthetic fibers

Dyeing method of polypropylene fiber

1) Pigment mixing method (master batch)

It now accounts for the majority of Colored (poly) fiber spun yarn.

There is a risk of discoloration due to pyrolysis depending on the pigment, and it is constrained to show various colors due to the necessity of making master batch of each color.

In the case of the polyester yarn dyeing yarn, it is necessary to carry out a process such as twist processing, pretreatment of dyeing, dyeing, winding, etc. However, polypropylene has advantages of reducing the cost of dyeing processing because it is subjected to only the flouring process without the pre-dyeing process and dyeing process.

2) Development method of disperse dye

There is no example of development of a dye which gives commercially satisfactory color and fastness by selecting or developing a special dispersion dye having good solubility in a polypropylene fiber composed of hydrocarbon.

3) Introduction of polar group by polymer modification

It is difficult to control the physical properties of the radicals generated during graft copolymerization or to control the length of the polar monomer uniformly during graft copolymerization, thereby causing a problem in the uniformity of the fiber quality.

4) Physical Compounding Method

(Ethylene-co-Vinylacetate), which has a hydrophilic group, is added to a hydrophobic polypropylene Chip to compounding it. This method is excellent in radioactivity and dyeability, but has a problem in workability.

5) Method of introduction of functional groups by chemical treatment after irradiation

 The method of irradiating polypropylene fiber with electron beam, gamma ray and plasma in the air and introducing a seated seat by treating the chemical with a chemical thereto has not reached the commercialization stage completely.

Application of polypropylene fiber

Polypropylene fiber is lightweight because it has a low specific gravity and low thermal conductivity.

Because it does not contain moisture, it does not have a bacterium itself and has its own antibacterial function. Using antibacterial treated polypropylene fiber can be used as health fiber that can be relieved from bacteria as well as bad smell.

When applied to swimwear using lightweight, quick-drying, and chemical-resistant characteristics of polypropylene fiber, it is advantageous to secure competitiveness as a differentiating item.

Polypropylene fiber is not only the lightest among all fibers but also floating material in water, so it maximizes buoyancy and fiber does not absorb moisture, so it is quick to dry after swimming and has excellent chemical resistance, so it is not affected by chlorine. Therefore, when used in combination with chlorine-treated spandex, it can prevent popping even if it is worn only a few times as in a conventional swimwear.

Since polypropylene fiber is hydrophobic and has a thermal insulation effect, it can maintain a certain body temperature even at the bottom of the sea. In addition, since it is dried outside of water in a short time, it can be used for skin sports such as skin scuba, windsurfing, water skiing, canoe, It is a material suitable for deployment.

Wearing a knit sports shirt with polypropylene that is lightweight and has excellent moisture output, you can exercise under optimal conditions, and it is easy to wash after use. Therefore, it can be combined with various items ranging from professional sports wear, leisure wear such as aerobics wear, jogging wear, sports goods such as socks to caps, hair bands, and gloves.

Polypropylene fiber is lightweight due to its light weight and it has no worry of desalting and dyeing due to its excellent fastness and it is possible to make various patterns that take advantages of original yarn. Therefore, it can be used for various functions such as durability and recyclability It can be used in the fields of carpets, couch covers, car seat covers, and the like.

After the brass and silver bar were fixed to the electrolytic cell with a gap of 10 cm between them, the electrolytic device was fixed at a current of 3 volts and 13 amps for electrolysis to completely dissolve the brass rods and silver bars in the electrolytic bath, After decomposition, nanoparticles of about 5 nm to 30 nm in size were prepared by preparing a porous solution of a sericite silica gel composition,

In order to prepare the Masuda batch for polypropylene fiber, 1000 g of span tails are mixed with 200 g of polypropylene soft resin 200 g of polyethylene resin and 30 g of polyethylene glycol to the quantification and mixing process of raw material quantification and mixing process of Masuda batch manufacturing process. Then,

The nano-brass was mixed with 50 g of the porous solution of the sericite-silica gel composition and then transferred to a drying step and dried at a drying temperature of 120 ° C. to completely evaporate the water. Then, the nanow brass was transferred to a melt extrusion step, And the cooled resin was transferred to a cutting process to prepare a 3 mm long 3 mm diameter Masuda batch for polypropylene fibers,

The extruded melt was kept at 0 ° C for 30 seconds to 1 minute in a cooling process,

After stretching and stretching to the stretching process, it was stretched and cleaned by a cleaning process, then transferred to a drying process, allowed to stand at a hot air temperature of 80 ° C for 1 minute, dried, and then transferred to a cutting process. After producing the used fiber,

The polypropylene fiber is transferred to a spinning plant to produce a polypropylene fiber yarn, and the fiber is transferred to a spinning process according to spinning yarn manufacturing process, followed by hatching, followed by cutting to a cutting process, followed by cutting to transfer to a softening process, After transferring to the coping process, the yarn is transferred to the spinning process, and 30 spinning yarns are produced. A polypropylene yarn wound around a cone of 1 kg or 2 kg in a winding process (winider) is prepared,

The polypropylene yarns that can improve the warp and post dyeability of the polypropylene fibers will be briefly described as follows.

It is called "polyurethane fiber", which is called "polyurethane fiber" because it has excellent elasticity and flexibility. It is a rubbery high elastic fiber which is not found in other fibers. It is a material with excellent elasticity and flexibility. Especially, SpanTax is a polypropylene fiber raw material, Several thousands of spintaxes were mixed and melted up to 130g in Resin 1000G and used as experimental results.

As for the production method of span tack, that is, the urethane fiber raw material, since the spinning method is carried out in a solvent such as dimethylformamide or the like and is radiated dry or wet, the other polymeric resin raw materials are not produced in the form of co- Regardless of the thickness of the yarn (DaNia), spuntacks are cut at intervals of 0.5 mm-1 cm and used as a raw material for the production of masuda batch for polypropylene fiber yarn, which is a raw material of polypropylene yarn.

Particularly, a small amount of polyethylene glycol was used as a raw material used in the production of a masda batch for a polypropylene fiber, because a small amount of polyethylene glycol which can be melted in a polypropylene resin was used by mixing.

Polyethylene glycol used in the new softener for post-processing to postproduce the polypropylene yarn again in the wine die process was used because of its excellent water absorption and lubricity.

Ethylene glycol also has excellent water absorption ability and surfactant made of glycerin fatty acid ester, which is a nonionic surfactant in polypropylene spun yarn, also has moisture absorbing ability, so that the polypropylene spun yarn is not dried well and has flexibility and lubricating water absorption ability .
