Manufacturing method of superfine yarn fabric with high dying fastness and high absorbent textiles hence

The present invention relates to a method for producing a microfiber fabric having excellent dye fastness, and to a super absorbent garment thereby. More specifically, a method for producing a microfiber fabric having improved color fastness and dye appearance by optimizing processing by using a general microfiber yarn. And a super absorbent garment thereby.

Since the 1980s, ultra-fine fibers of hundreds of thousands of deniers have been developed by new spinning methods in the field of chemical fibers.

The new spinning method is a composite spinning method, which spins two or more polymers at the same time through a specially designed spinneret and then dissolves and removes one polymer component or splits the heteropolymer by chemical or physical methods to obtain ultra-fine fibers. In addition, the island-in-the-sea microfiber yarn which obtains ultra-fine fibers by dissolving and dissolving one component after spinning a heterogeneous polymer in an island-in-sea type is the mainstream.

The ultrafine fibers developed in this way have a very soft touch and are highly absorbed and absorbed by capillary phenomena embodied by ultra-fine gap pores formed in a woven fabric. It has been developed as a textile product to meet the needs of human beings.

One of the development uses of such ultrafine fibers is a cleaner using superabsorbent and absorbent properties, which are characteristics of ultrafine high-density fabrics, and also superabsorbent garments such as bathrobes and beach towels using superabsorbent and soft touch and warmth.

However, although the ultra-fine fibers have a myriad of fascinating advantages, there are also fatal drawbacks, which continue to impede product development.

It is a matter of dyeing and dyeing appearance quality, because the surface area of the ultra-fine fibers has a large surface area, which causes scattering and desorption of dyes, so that washing fastness, friction fastness and light fastness are not all good, especially in deep color, and the fiber is very fine. Due to the large surface area, light scattering occurs a lot on the surface of the fiber, so that the color is not clear during neutral and deep dyeing.

In addition, bleeding was a problem because of poor friction fastness, and in particular, the use of towels, which have a lot of contact with the skin, has become a critical obstacle.

Much research has been done to overcome this dyeing problem.

As an example, Korean Patent Laid-Open Publication No. 1996-23482 attempts to solve a dyeing problem using an original yarn, but there is a problem of cost increase due to the use of the original yarn, and the problem of pure color expression still remains. In addition, Korean Patent Publication No. 1997-43579 discloses a method of dyeing artificial leather, in which 30 to 50 parts of dyes are added and dyed first, followed by dyeing by adding 50 to 70 parts of dyes and acetic acid at 60 to 70 ° C. , Publication No. 1997-43574, first impregnated with a polyurethane foam and treated with a pigment, dyed water for 50 to 70 minutes at 100 to 120 ℃ using a metal complex dye, and washed again with a metal complex dye Although a dyeing method of artificial leather is disclosed, which is reduced dyeing with oxidizing dyes corresponding to the range of 10 to 15% by weight, oxidized color development, followed by soaping treatment, and treatment with an anionic type softener and washing with water, The solution was limited due to the inherent characteristics of the ultrafine fibers.

Dyeing quality of conventional cotton fabrics and synthetic fabrics for beach towels and bathrobes is good, but cotton fabrics are not beautiful in appearance and soft to the touch, and synthetic fabrics such as polyester fabrics of Tadenier are vivid and dyed. The quality was good but it was poor in absorbency and touch.

The inventors of the present invention completed the present invention after endeavoring to develop a superabsorbent garment which is beautiful in appearance and excellent in color fastness as well as expressing high absorbency and soft touch, and without pure color expression in deep colors.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to maintain a soft touch, such as suede, while excellent dyeing fastness and no dyeing and pure color expression method for producing a microfiber fabric In providing.

Another object of the present invention is to provide a super absorbent garment which is excellent in color fastness and free of dyeing while maintaining a soft touch such as suede.

The method for producing a microfiber fabric having excellent dyeing fastness of the present invention is a weaving step of weaving a double main weaving yarn with a single yarn fineness of 1 to 5 denier polyester yarns and a single yarn fineness of 0.1 to 1 denier polyester microfiber yarns as a weft yarn; Brushing step of brushing the front and back surfaces by 10 to 30 m / min 2 to 6 times by brushing brushing, respectively, 1 to 3 times as looping brushing and 1 to 3 times of cutting brushing; Short shearing from 0.003 to 0.1 mm; Refining weight loss and dyeing by known methods; It is set to 1 to 3 times for 10 to 40 minutes at a temperature of 180 to 190 ℃.

In the present invention, transfer printing may be performed after the setting step.

In the present invention, the polyester yarn may be recognized as a conventional polyester yarn in the art, it is understood that not only polyethylene terephthalate (PET) but also polybutylene terephthalate (PBT), copolyester, etc. may be employed. Could be.

In the present invention, the weaving is preferably made of the same structure of the front and back.

According to the present invention, there is provided a method for producing a microfiber suede-like fabric excellent in color fastness (washing, daylight, friction, etc.).

According to the present invention, there is provided an effect of providing a super absorbent garment product made of microfiber fabric without the drawbacks of microfiber suede fabric, such as dripping, dyeing, pure color expression.

According to the present invention, there is an effect that a high-absorbent clothing such as high-quality jade towels, bathrobes, shawls and the like with a clear color, soft to the touch and excellent printability.

The present invention will be described in more detail below.

The method for producing a microfiber fabric having excellent dyeing fastness of the present invention is a weaving step of weaving a double main weaving yarn with a single yarn fineness of 1 to 5 denier polyester yarns and a single yarn fineness of 0.1 to 1 denier polyester microfiber yarns as a weft yarn; Brushing step of brushing the front and back surfaces by 10 to 30 m / min 2 to 6 times by brushing brushing, respectively, 1 to 3 times as looping brushing and 1 to 3 times of cutting brushing; Short shearing from 0.003 to 0.1 mm; Refining weight loss and dyeing by known methods; It is set to 1 to 3 times for 10 to 40 minutes at a temperature of 180 to 190 ℃.

In the present invention, first, a single yarn fine yarn of 1 to 5 denier polyester yarns is inclined, and a single yarn fine yarn of 0.1 to 1 denier polyester microfiber yarn is used as a weft, and weaving is performed in a double main fabric. More preferably, the double runner is double satin.

The warp of the fabric that can be employed in the weaving step may be employed as the warp of the medical fabric and is not particularly limited as long as single yarn fine polyester yarn of 1 to 5 denier, 75d / 36f, 75d / 48f, 100d / 36f, 100d Polyester yarns of various specifications such as / 48f can be used. If the single yarn fineness is less than 1 denier, the appearance of the final fabric is not good, the fabric has no strength in the weaving state, which is not advantageous for processing, and if the single yarn fineness exceeds 5 denier, the product becomes too stiff so that processing such as raising is smooth. There is a disadvantage that it is not good and above all, the drape or flexibility of the final product is inferior.

The weft of the fabric that can be employed in the weaving step is a polyester microfiber yarn of single yarn fineness of 0.1 to 1 denier. This polyester microfiber is a so-called general microfiber, manufactured using general spinning rather than composite spinning, and the yarn specifications that can be effectively employed in the present invention are 0.1 to 1 denier, 50d / 96f, 65d / 192f, and 75d / 144f. , 75d / 192f, 100d / 192f, 150d / 216f, 150d / 384f, 150d / 408f, 200d / 384f and the like can be employed.

When the weft yarn fineness of the weft yarn is less than 0.1 denier, dyeing fastness in deep color is reduced and problems such as pure color development occur, and when it exceeds 1 denier, soft touch and high absorbency as microfiber yarn cannot be achieved.

In the present invention, the weaving tissue is preferably a double-woven fabric because it has a bulkiness and good absorbency due to the characteristics of superabsorbent clothing such as beach towels, and is also preferable for double-sided brushing. Plain or twill weave is not bulky and is not suitable for double-sided raising.

In the present invention, the brushing step carried out after the weaving step is brushed 2 to 6 times by brushing brushed at 10 to 30 m / min on the front and back, respectively, 1 to 3 times as a loop brushed 1 to 3 Three times brush cutting.

The number of brushings will be understood by those skilled in the art under optimized conditions to maintain optimal brushing length, feel and high absorbency for product purposes.

Following the raising process, the hair removal process is performed, and the raising length in the total hair is shortened to 0.003 to 0.1 mm. If the brushed hair in the shearing is shortened out of range, it may not achieve a soft touch and high absorbency, and if it is long, dyes may be difficult to penetrate to the inside during dyeing, resulting in poor dyeing.

The hair dyeing process is followed by a dyeing process, which may be understood to be carried out by a conventional polyester fabric dyeing method for dyeing the base material, and a description thereof will be omitted.

After the dyeing process, in the case of light color (light color) such as blue, green, ivory, white, and optionally, a post-treatment step for treating a drug such as a sunfastness enhancer or a sunscreen is optionally performed to improve the lightfastness. May be

Next, in the present invention, the setting operation is performed, the setting step of the present invention is carried out by repeating 1 to 3 times for 10 to 40 minutes at a temperature of 180 to 190 ℃.

When using a nylon / polyester composite microfiber, the setting temperature cannot be increased due to the nylon component. However, in the present invention, since the composition temperature is 100% polyester, the setting temperature can be increased. It has the advantage of being.

In the present invention, after the setting, the transfer printing process may be finally performed if necessary due to the characteristics of the product. This transfer printing process is the same as the transfer printing method for a conventional polyester fabric, so a detailed description thereof will be omitted.

In the present invention, the polyester yarn may be recognized as a conventional polyester yarn in the art, it is understood that not only polyethylene terephthalate (PET) but also polybutylene terephthalate (PBT), copolyester, etc. may be employed. Could be.

In the present invention, the weaving is preferably made of the same structure of the front and back. Otherwise, the workability will be poor because the conditions for raising will be different.
