Description

MANUFACTURING METHOD OF ULTRAFINE FABRICS WITH MELANGE APPEARANCE, ITS PRODUCT AND USE THEREOF}

The present invention relates to a method for producing a microfiber fabric having excellent melange appearance, and to a microfiber fabric prepared therefrom, and more particularly, to a yarn processed by combining an original microfiber yarn and a general microfiber yarn, or to the original microfiber yarn and the original microfiber yarn. Method for producing ultra-fine fiber cloth with excellent melange appearance consisting of weaving, knitting or dyeing high-shrink yarn into three-ply composite twist or three-ply interlaced yarns with warp, weft or warp and weft yarn To ultrafine fiber cloths and uses thereof.

Synthetic fiber with excellent physical properties has been used as a yarn for clothing with natural fiber for a long time, but synthetic fiber has a problem that it is not soft and soft to the touch.

As one method of imparting a soft touch like synthetic fibers to synthetic fibers, ultrafine synthetic fibers having a monofilament fineness (monofilament fineness) of 1.0 denier or less have been developed. Such ultra-fine synthetic fibers are expanding rapidly because they have the feel and functionality of natural fibers and are easy to process, easy to handle, and mass-produced at low cost.

Usually, the ultrafine synthetic fibers are produced by direct spinning or composite spinning.

However, the direct spinning method is difficult to manufacture ultra-fine synthetic fibers of less than 0.1 denier because it is directly spun through the detention, and various problems occur in the processing and weaving stage.

On the other hand, in the method of complex spinning, two-component composite yarns are produced by complex spinning of different polymers such as polyester / polyamide composition or polyester / copolymer polyester composition, and then two-component composites are prepared by physical or chemical methods during the post-processing process. It is prepared by separating and dividing the monofilament of the fiber-forming component in the company. Therefore, it is easy to manufacture ultra-fine fiber cloth of 0.1 denier or less, and since the monofilament is separated and divided during the post-process, it is easy to complex with other fibers and has good processing and weaving processability.

However, when the two-component composite yarn prepared by the composite spinning method is used alone in a knitted fabric, there is a disadvantage in that buffing, thickening, drape, and rupture strength are poor. In particular, in the case of the composite spinning of the polyester / copolymer polyester composition, since the copolyester is extracted by the weight loss, a space is formed between the knit fabric tissues, and the drape of the fabric and the rupture strength are severely reduced.

In order to solve the above problems caused by the use of ultra-fine synthetic fibers or two-component composite yarns alone, a method of combining ultra-fine synthetic fibers and other fibers has been widely studied. As an example thereof, Korean Patent Laid-Open Publication No. 1998-55564 discloses that a two-component composite yarn in an unstretched state is stretched and burned, and then fed into the high shrink yarn and the air processing nozzle at the same overfeed rate, and then air is entangled in two components. It suggests a method of combining composite yarn with other fibers.

In addition, in an effort to give the appearance as a natural fiber (melange), the Republic of Korea Patent No. 2003-18060 is a two-component composite yarn or fiber formability composed of two or more types of fiber-forming components that are different from each other dyeing characteristics It is composed of a component and an eluting component and known to the process for producing a bi-shrink blend fiber yarn excellent in the melange effect, the air processing the two-component composite yarn in an air processing device, the bi-shrink blend fiber yarn excellent in the melange effect of the present invention is formed Two or more two-component composite yarns (superfibers) with different dyeing characteristics of the component are wound around the thermoplastic multifilament (examination), and have excellent melange effect and excellent monofilament dispersibility in the production of knitted fabrics. It is disclosed that the hair density is high and the hair is uniform to express an excellent Suede effect.

The "melange effect" refers to the effect of mixing a variety of colors when dyed to have the appearance as a natural fiber, "swede effect" refers to the effect of expressing the feel and appearance like natural leather.

However, in the present invention, after using a two-component composite yarn composed of two or more kinds of fibrous forming components different from each other in dyeing characteristics, when the dyeing process to give the melange appearance, 1) fastness due to the use of excess dye of two components It may cause a problem, 2) due to the phenomenon of mutual cancellation when the color is expressed by the dyeing of the two components, there is a disadvantage that the appearance of the melange of the surface for each color is not expressed.

In addition, conventionally, since there is no technology to give a melange appearance to the surface of the ultra-microfiber products (suede and split yarn products), the situation is dependent on a monochromatic color product having a single color surface.

In order to overcome this simplicity, after the dyeing process, the surface of the product is treated with a post-processing process such as printing or chemical embossing to overcome the simple appearance, but the printing and chemical embossing not only cause environmental problems, but also touch the surface. It is becoming a factor to make it.

Another method is to change the appearance of monochromatic color with the use of different dyes in dyeing, using cationic dye caustic dye yarn as warp or weft yarn and ultra-fine yarn as weft or warp yarn. Appearance is not expressed and not only the two-tone or tone on tone effect is expressed, but also the weakness of daylight fastness of the product due to the weakness of daylight fastness of the cationic dye dyeable dye. have.

In Japan, efforts have been made to give a natural fiber appearance by combining with a colorless ultrafine yarn using "Cosmo-α (Kanebo) -Cation dye-inflammable ultrafine yarn". 1) One light fastness problem of caching dye chlorinated dyes, and 2) Cation dye caustic ultrafine yarns are also dyed in disperse dyes, which implies that natural fiber appearance is not expressed in medium / dark colors.

Therefore, the present inventors have tried to solve the shortcomings of the conventional two-component composite yarn, as a result of combining the original ultrafine yarn and the general ultrafine yarn to be used as a yarn processed, the same component without using a dichroic yarn To give a melange appearance to the polyester surface of the yarn, and further weaving the high shrink yarn into the composite micro-composite or triple-complex interlacing method of the original microfiber and general microfiber with a warp, weft or warp and weft yarn By dye processing, not only can you get a soft feeling and excellent fastness on the surface of the ultra-fine fiber cloth product by maximizing the shrinkage of high shrink yarn, but also the surface of the ultra-fine fiber cloth that fully expresses the softness of the surface through brushing or buffing process in the dyeing process. This invention was completed by confirming manufacture.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing an ultrafine fiber cloth having excellent melange appearance using yarns pretreated with polyester-derived ultrafine yarns and nylon or polyester general microfine yarns.

It is another object of the present invention after the polyester spun yarn superfine yarn and nylon or polyester general ultrafine filament, and then the yarns, which are high-shrink yarn, tri-compound composite or three-ply co-interlacing method with respect to the yarn weight It is to provide a method for producing a superfine fiber cloth excellent in melange appearance.

Still another object of the present invention is to provide a use of ultra-fine fiber cloth having excellent melange appearance produced by the above-described manufacturing method.

In order to achieve the above object, the present invention is inclined, weft or warp and weft of composite twisted or interlaced yarn in a ratio of 30 to 70% by weight of the original ultra-fine yarn and 70 to 30% by weight of ordinary microfiber, weaving or knitting It provides a method for producing a super-fine fiber cloth excellent in the melange appearance consisting of.

Monofilament fineness of the polyester primary ultrafine yarn and nylon or polyester general ultrafine yarn after the said composite twist or interlacing process is 0.03-0.5 denier.

The original ultra-fine yarn is characterized in that 100% polyester, more specifically, the polyester original ultra-fine yarn is a microfiber yarn, sea island yarn, elution yarn, Partially Oriented Yarn (POY) and processed yarn (Draw Textured Yarn, DTY) Any one selected from the group consisting of is used.

In addition, the yarn is a composite flame retardant or interlaced by mixing a polyester-based ultra-fine microfiber selected from black or red color and white nylon or polyester general microfiber, the same without using a dichroic yarn It gives a melangeal appearance to the polyester surface of a component.

In addition, the present invention, after splicing the polyester-derived ultra-microfiber and nylon or polyester general microfiber, and 15 to 20% by weight of the high shrink yarn with respect to the weight of the yarn, three-composite composite or triple-complex interlacing method It provides a method of producing a super-fine fiber cloth excellent in the melange appearance consisting of weaving or knitting the yarn processed into a warp, weft or warp and weft yarn, and salt processing.

The high shrink yarn is 100% polyester.

The present invention provides a suede texture clothing or furniture material using the ultra-fine fiber cloth excellent in melange appearance produced by the manufacturing method.

Hereinafter, the present invention will be described in detail.

A first aspect for realizing the object of the present invention is to weave yarns pre-machined at a ratio of 30 to 70% by weight of polyester-derived microfiber yarns and 70 to 30% by weight of nylon or polyester general microfiber yarns as warp, weft or warp and weft yarns. Another aspect of the present invention is to provide a method for producing a superfine fiber cloth having excellent melange appearance, which is knitted and processed.

In the above production method, in order to give the inherent softness of the ultra-fine fiber cloth, the monofilament fineness of the polyester-derived ultra-fine yarn and the nylon or polyester general ultra-fine yarn after the composite twist or interlace processing is preferably 0.03 to 0.5 denier, the degree of melange appearance By adjusting the ratio between the original ultrafine yarn and the general ultrafine yarn according to the present invention, various natural fiber (melange) appearances can be obtained.

At this time, if the monofilament fineness of polyester-derived ultra-microfiber and nylon or polyester general micro-microfiber is less than 0.03 denier, there exists a problem about fastness, and when it exceeds 0.5 denier, there exists a problem that the softness of a product falls.

In addition, the ratio of the original microfiber yarn and the general microfiber yarn is preferably 30 to 70% by weight of the original microfiber yarn and 70 to 30% by weight of the general microfiber yarn, and when the primary microfiber yarn is less than 30 wt%, the deep melange phenomenon is reduced, and 70 wt% If it exceeds, it is not preferable to reduce the melange phenomenon due to the appearance of too dark color.

In particular, the manufacturing method of the ultra-fine fiber cloth excellent in the melange appearance of the present invention is characterized in that the original ultra-fine yarn is 100% polyester, more specifically, the original ultra-fine yarn of the present invention is a microfilament having a monofilament fineness of 0.03 to 0.5 denier , Any one selected from the group consisting of island-in-the-sea yarn, eluted yarn, semi-stretched yarn (Partially Oriented Yarn, POY) and processed yarn (Draw Textured Yarn, DTY) can be used.

The primary microfiber yarn is black or red color, and the general microfiber yarn is a white color, and the present invention, by combining the primary microfiber yarn and the general microfiber yarn, and then using a processed yarn, does not use a dichroic yarn. In addition, the melange appearance can be given to the polyester surface of the same component. In addition, by minimizing the dye amount of the disperse dye during dyeing by the color of the ultra-fine microfiber yarn, it is possible to minimize environmental problems, to obtain excellent fastness.

The general ultrafine yarn used in the present invention has a monodenier after processing of 0.03 to 0.5 denier, and preferred examples thereof include nylon and polyester ultrafine yarn (seaweed yarn).

In addition, a second aspect for realizing the object of the present invention is a polyester composite ultra-fine yarn and nylon or polyester general microfiber yarn, then 15 to 20% by weight of the high shrink yarn 3 triplicate composite flame or The present invention provides a method for producing an ultrafine fiber cloth having excellent melangeon appearance, which is obtained by weaving or knitting yarns that have been processed by three-way simultaneous interlacing method into warp, weft or warp and weft yarns, and dyeing them.

As a general interlacing method, since most of the two-ply composite is difficult to control the tension for each yarn, the second aspect of the present invention is the general method of interlacing the original black microfiber and the colorless ultrafine yarn first, and then interlaced yarn As a method of interlacing with the high shrink yarn, a device having the same tension is applied to the original black microfiber and the colorless ultrafine yarn, and having three mels interlaced simultaneously with the high shrink yarn, thereby providing a yarn having excellent melange effect.

High shrink yarns (High Shrinkage Yarn) can provide a smooth feeling to the ultra-fine fabric cloth because it forms a sufficient loop (Loop) on the surface of the ultra-fine fiber fabric product by maximizing its shrinkage, as an example that can be used as a high shrink yarn in the present invention Polyester or nylon.

As for the content of high shrink yarn, it is preferable to use 15 to 20% by weight with respect to yarns which are combined with the original microfiber and general microfiber, and if less than 15% by weight, the factor of inhibiting soft touch expression due to low shrinkage It is not preferable to act as a, and if it exceeds 20% by weight, there is a problem that inhibits the soft feeling of the product.

In particular, the manufacturing method of the ultra-fine fiber cloth excellent in the appearance of the melange type not only gives a softness to the ultra-fine fiber cloth due to the use of high shrink yarn, but also gives the appearance of the natural fiber (melange type) on the surface and by using a minimum amount of disperse dye when dyeing Environmental problems can be minimized.

In addition, in the manufacturing method of the ultrafine fiber cloth excellent in the melange appearance, the primary ultrafine yarn and the high shrink yarn are 100% polyester.

Through the first and second forms for realizing the object of the present invention, the manufacturing method of the ultrafine fiber cloth can not only obtain an excellent natural fiber (melange type) appearance of the surface through the combination of the original ultrafine yarn and the general ultrafine yarn, High-shrinkage yarns can be fabricated by using yarns that have been fabricated using three-ply composite twisted or three-ply interlaced yarns for warp or weft, warp and weft yarns. Since a sufficient loop is formed on the surface of the ultra-fine fiber cloth product due to maximizing shrinkage, a soft feeling can be obtained, and excellent color fastness can be obtained by minimizing the amount of dye used by the color of the primary microfiber yarn. In addition, since it is possible to provide a super-fine fiber cloth that fully expresses the softness of the surface through the brushing or buffing process in salt processing, it is possible to improve the characteristics required for suede products.

The present invention provides the use of a suede texture of clothing as the ultra-fine fiber cloth, i.e., the ultra-fine fabric or knitted fabric produced by the method for producing the ultra-fine fiber cloth of the first and second forms is given a softness and a natural natural fiber appearance of the surface. do.
