METHODS FOR PRODUCTING CHENILLE FIBER WITH HIGH ABSORPTIVENESS}

The present invention relates to a method for producing a superabsorbent Chanel fabric, and more particularly, using a non-fused yarn as the screening, and using a composite fiber as an adverb to manufacture a Chanel yarn, weaving it, and placing the fabricated Chanel fabric It relates to a method for producing a super absorbent Chanel fabric produced by weight reduction in a weight loss device.

Textile materials, which are indispensable in human daily life, have been diversified over the long history, and their functions are becoming more functional and superior. As the textile material industry is highly developed, the comfort of textile materials is regarded as an important property that can influence the quality and added value of the materials when applied to the human body or in use. In particular, the comfort of these materials The most important physical property is the absorbency and hygroscopicity of the material, and there have been many studies on the material which quickly removes the sweat emitted from the human body or the moisture generated from the outside. In other words, the basic function of the comfortable material required in the market is a moisture absorption function to quickly control the sweat emitted from the skin so that the human body feels comfortable.

Traditionally used for materials requiring absorbency and absorbency, cotton is representative as a natural material having advantages such as abundant resources and low price, and cellulose regenerated fibers such as rayon and wool have been used. Materials such as cotton and rayon have a very good absorbency due to the -OH group of cellulose molecules, and the absorption rate reaches about 8-12%, which is a representative superabsorbent natural fiber material.

However, these natural fiber materials have various problems in fugitive, shrinkproof, laundry resistance, dyeing, insect repellent and antibacterial resistance, and when used for cleaning and kitchen utensils other than clothing, due to friction or washing There is a problem that is not only visually unpleasant due to the occurrence of debris of the fiber, which is a problem specific to short fibers, and also in terms of hygiene such as respiratory diseases.

Due to these problems, there are limitations in developing various types of products with natural fibers, which makes it difficult to develop further.

In order to replace and improve the absorbent products composed of such natural materials, various development attempts have been made using synthetic fibers since the 1990s, and in some cases, synthetic fiber replacement products having superior absorbency than natural materials, typically microfiber yarns using composite fibers. Products have been developed and applied to real life.

Korean Patent Laid-Open No. 93-10258 uses a windmill-like composite fiber manufactured by adding a small amount of polyester to a fiber-forming polyamide as a first component and a fiber-forming polyester as a second component, with a weft yarn By fabricating a woven fabric using a fiber as a warp, and then performing an alkali weight reduction process, the surface modification of the polyamide fiber and the windmill sectionalization of the windmill-type composite fiber have been carried out, thereby providing an absorbent quick-drying knit fabric having a feeling of touch and cooling.

Republic of Korea Patent Publication No. 99-15108 is a high-hygroscopic cleaning forge, characterized in that the knitted composite fibers obtained by the composite spinning of nylon / polyester as a front and back loop yarn, the composite yarn and polyester in the middle as a reinforcing yarn Japanese Patent Application Laid-Open No. 8-27626 discloses a lightweight fabric by spinning a fiber composed of a composite component of 30-50% by weight of polyester to 70-50% by weight of polyamide to produce a knitted fabric, and then performing alkali treatment. The potential for the fabrication of apparel fabrics with the functions of absorbing and absorbing water and water is suggested.

The microfiber material using the composite fiber listed above is a very thin fiber having a diameter of about 1 to 6 μm, unlike a general synthetic fiber, and has a feature of having a large water absorption space. Since the absorbency difference is large depending on whether the physical properties of the fiber are changed, knitted fabric products incorporating processing techniques for various fiber yarn processing have been developed.

As an example, Japanese Patent Laid-Open No. Hei 7-63438 proposes a functional product that is superior to general microfiber products by making a hygroscopic material by manufacturing a fancy yarn using a Nakamura soft yarn among the design yarns.

In addition to the design yarns, Chanel yarns can be cited as a method that can be produced in fancy yarns by utilizing microfiber yarns having excellent absorbency, water functionality, and feel. Chanel (chenille) is a kind of decorative yarn, which is made by first weaving the fabric, cutting the weft (adverb) in an oblique direction, and then twisting the weft. Tea is a high-level chairman who is called the office.

Chanel yarns are fixed with an adverb on the inclined slope to form a wing yarn, bringing a soft and bulky touch, and weaving can be made with an absorbent fabric. However, the existing Chanel yarn (using cotton yarn as an adverb) is dusty from the cut adverb. Has many disadvantages and has a weak friction fastness, in particular, there is a defect that the adverbs are pulled out.

In addition, the present applicant has been studying how to apply microfiber to Chanel yarn which generates less dust than the natural fiber and has no fiber scrap and excellent in absorbency and feel. However, the fineness is relatively small and the surface is relatively relatively compared to the natural fiber. Due to the nature of smooth microfibers, there have been technical difficulties in which the problems of adverb detachment from the examination are not solved.

In order to solve this problem, the technology of fixing the adverbs by fused screening by using low melting polyester fiber as the screening has been proposed. There was a downside to dropping.

Although it is an ultrafine yarn that is excellent in touch and absorbency, there has been a problem as described above in applying it to Chanel, and thus, the manufacture of Chanel using microfiber has not been successful.

The present invention is to solve the problems of the prior art as described above, to provide a method for producing a super absorbent Chanel fabric without the residue of the yarn, such as a linter occurs when using natural fibers.

In addition, the present invention is to provide a method of manufacturing a Chanel fabric using a microfiber yarn excellent in absorbency and feel.

In addition, the present invention is to provide a method for producing a super absorbent Chanel fabric which can prevent the microfibers, which are adverbs, from being easily detached from the screen due to physical friction or washing.

In addition, the present invention is to provide a method for producing a superabsorbent Chanel fabric that can prevent the adverb detachment while preventing the screening, which is a low melting synthetic fiber, from hardening the texture of the fabric.

Figure 2 is a cross-sectional view of one embodiment of the Chanel yarn of the Chanel fabric produced by the present invention,

3 is a cross-sectional view of one embodiment of a Chanel yarn of a Chanel fabric produced by the present invention.

In order to achieve the above object, the present invention provides two screenings which are used as inclined while crossing each other in opposite directions; And a superabsorbent Chanel yarn composed of 2 to 4 bone adverbs which are included as weft yarns in the space formed by crossing the screens, wherein a non-fused yarn is used as the screen yarn, and the two components are used as the adverbs. A primary weaving step of weaving the screening and adverbs, including one or more composite fibers consisting of the above synthetic fibers; A spinning step of cutting the adverbs of the fabric obtained in the weaving step and spinning them with Chanel yarn; A secondary weaving step of manufacturing a fabric comprising Chanel yarn obtained in the spinning step; It provides a method for producing a super absorbent Chanel fabric comprising a processing step of reducing the second weaving step of the fabric in a batch type weight loss device to express the composite fibers of the Chanel yarn included in the fabric into microfiber.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

Figure 1 shows an embodiment of Chanel's company that can be used in the manufacturing method of the present invention. The illustrated Chanel yarn is formed with an adverb 250 in a pile shape, and basically, two examinations 210 fix two to four adverbs 250. At least one of the adverbs 250 is a composite fiber, and when the weight loss processing in the processing step, the composite fiber is divided into microfibers so as to form a janggu shape as shown in the drawing so as not to fall out of the screening 210.

As the screening used in the production method of the present invention, false twisted yarn of synthetic fibers is used, which does not correspond to low melting synthetic fibers (hereinafter, 'non-fused yarn').

In the present invention, a low melting point synthetic fiber refers to a synthetic fiber having a melting point of 150 ° C. or lower, which may have an effect of being fixed by adverging with an adverb in a dyeing process, but it is not preferable to use because it deteriorates the texture by curing the fabric. not.

The disadvantage of loosening the adverb by using non-fused yarn in the manufacturing method of the present invention can be compensated by the weight loss processing in the batch type weight loss device after the secondary weaving, as described below. In addition to the main examination, it may be supplemented by adding a third examination of the role of fixing the adverbs.

The batch weight loss device is one of the general preprocessors and is a facility corresponding to the continuous weight loss device. The biggest difference between batch type and continuous type is that continuous type is supplied to the equipment and processed continuously, whereas batch type is supplied and processed to the facility by a certain amount. In addition, in the continuous type, a tension is applied to the inclined direction of the fabric because a constant tension is applied from the end of the workpiece to be supplied, that is, the fabric, but the batch type minimizes the tension applied to the inclined direction of the fabric than in the continuous type. It can be characterized. For this reason, the weight loss in the continuous installation is made by smoothly spreading the surface of the fabric and the surface appearance is uniform and smooth, whereas the weight loss in the interior of the fabric is not uniform. On the other hand, as in the present invention, when the fabric containing the Chanel yarn is reduced in the batch equipment, it is possible to minimize the tension in the inclined direction, the fabric portion immersed in the weight loss solution (caustic soda) overlap the overlapping fabric The physical contact between the parts occurs so that the division of the composite yarn in the weft direction not only to the outside but also to the inside of the fabric is relatively more advantageous than that performed in the continuous installation.

Synthetic fibers that can be used as the screening in the present invention may be synthetic fibers made of polyamide, polyester, acrylic fibers, etc., in a preferred embodiment of the present invention the synthetic fibers are 50 to 150 d polyester flammable It can be four.

In the present invention, the screening is used as a warp when weaving (primary) weaving for the production of Chanel, and serves to fix the adverbs that are weft yarns. It is possible to configure. Among the examinations of the present invention, the first examination and the second examination may fix two or four adverbs between the spaces while being alternated with each other, and the third examination may separate the upper and lower parts of the two or four adverbs separately from the remaining examinations. Adverb can be fixed while depressing.

Referring to FIGS. 2 and 3 embodying an example of the Chanel yarn included in the Chanel yarn fabric of the present invention, FIG. 2 is a three-part adverbs 350 fixed with the first screen 310 and the second screen 320. The cross-sectional view of the Chanel yarn of the interlocking structure while the third screen 330 is squeezed up and down of each oar, and FIG. 3 shows two sections of the four adverbs 350 and the third screen 330 is the top and bottom thereof. Fig. 1 shows a cross section of Chanel's intersecting structure. In addition to the Chanel yarns shown in the drawing above, three adverbs are divided into 2 ol-1 ols, and the third judging subtracts up and down, or 4 adverbs are divided into 2 ol-1 ol-1 ol, and the third judging Of course, possible implementations are possible.

The adverb used in the present invention includes one or more composite fibers in which two or more synthetic fibers are conjugated. The composite fiber is divided by alkaline weight loss processing in the weight loss processing step, and is made of microfiber, and after the weight is reduced, the volume becomes bulky, the voids are increased, and the absorbency is increased, so that it is more firmly fixed by the screening and the soft touch as the microfiber. Can be expressed to have. If the composite fiber is generally used in the production of microfiber yarn, both bilayer composite fiber and multilayer composite fiber can be used as the adverbs of the present invention, such as side by side type, core and sheath type, parallel type, radial type, and matrix dispersion type. Composite fibers such as can be used.

In one preferred embodiment of the present invention, the adverb may be three side-by-side composite fibers and one cotton yarn of polyester and polyamide. Moreover, when the composite fiber used as an adverb of this invention is a bicomponent composite fiber of polyester and polyamide, it is preferable that the component ratio is a weight ratio of 70:30-80:20. In another embodiment of the present invention, the adverb may be one radial composite fiber and two cotton yarns having a weight ratio of polyester and polyamide of 70:30.

In addition, as an adverb of the present invention, natural fibers, semi-synthetic fibers, etc. may be used in addition to the composite fibers. In general, the composite fiber is a high-cost yarn that must undergo a composite spinning and weight reduction process, so that the cost can be reduced through the use of other fibers, and it is possible to maintain a high level of absorbency by using a fiber having excellent water absorption such as cotton. . As in the preferred embodiment of the present invention, two conjugate fibers and one cotton fiber can be used as the adverbs, the adverbs of the present invention use two to four bones in combination from one or more composite fibers, natural fibers and semisynthetic fibers. It is desirable to. The present invention makes it possible to combine the adverbs among composite fibers, natural fibers and semisynthetic fibers, thereby making it possible to manufacture Chanel fabrics of various quality and cost according to the choice and taste of the manufacturer or purchaser.

In the present invention, the adverb is preferably in the form of a pile. In the case of using a U-shaped adverb, there is a problem that the adverb is easily removed from the screening and has poor durability and poor appearance when used for a long time.

As shown in FIG. 1, in the Chanel yarn used in the present invention, the adverbs form a pile and spread in a janggu shape around the screening after division, thereby making it possible to more secure the screening.

As described above, the Chanel yarn included in the Chanel fabric of the present invention has a long gear shape and does not easily deviate from the screening, and protrudes a super absorbent microfiber to the outside to have a luxurious appearance and excellent absorbency, It is possible to manufacture a super absorbent and high quality material that can suppress the generation of waste.

In the method of manufacturing the chanel fabric of the present invention, preferably, as described above, weaving and weaving are used as warp and weft yarns, respectively, as the warp and weft yarns (primary weaving step), and parallel to each screening (that is, the warp direction). ) Chanel yarn is manufactured by cutting the adverb at equal intervals and then burning it or folding the adverb (spinning step). Then, fabricated using the obtained Chanel yarn (secondary weaving step), and, as a feature of the present invention, alkali processing (reduction) in a batch type weight loss facility without pretreatment or pretreatment of the fabric obtained in the second weaving step. The treatment is carried out to divide the adverbs in the Chanel yarn contained in the fabric into microfibers (processing step).

The processing step of the present invention is a step carried out in a general weight loss to alkaline processing conditions in a general batch type weight loss equipment in a batch type weight loss device, through which the composite fiber used as the adverb is expressed as microfiber, thereby microfiber The interval between the openings is widened and the adverbs are spread into the janggu shape, so that the fixation by the examination can be increased.

Also, after the second weaving step, the dyeing step is additionally performed to further facilitate the division of microfiber yarns.

Thereafter, the chanel fabric produced in the manufacturing method of the present invention may be manufactured in various fabric forms. For example, it can be a fabric having a high-quality appearance and excellent absorbency in a variety of tissues, such as basic tissues such as plain weave, twill, runners, and deformed tissues, weaving into a single or double weave is also optional.

Chanel fabric prepared according to the present invention is used as a high-quality functional material having excellent appearance, surface effect and absorbency, and can be used as an industrial material in a wide range of fields such as towels, bath products, and automobile sofas.
