Description

Manufacturing method of super absorbent Chanel yarn {METHOD FOR PRODUCTING CHENILLE FIBER WITH HIGH ABSORPTIVENESS}

The present invention relates to a method for producing superabsorbent Chanel yarn, and more particularly, to a method for producing superabsorbent Chanel yarn using non-fused yarn as a screening and composite fiber as an adverb.

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 yarn is fixed on the warp yarn weft to form a wing yarn to bring a soft and bulky touch, and can be woven into a fabric with excellent absorbency, but the existing Chanel yarn (using cotton yarn as an adverb) is dust 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 the problem of missing adverbs, a technique of fixing the adverbs by fused screening by using low-melting polyester fiber as a screening has been proposed. There was a downside to dropping.

Microfiber is excellent in tactile feel and absorbency, but it is difficult to find commercial and commercial successes in the manufacture of Chanel using microfiber until now. It would be a major step forward in this field if Chanel could be manufactured and could overcome the problems noted previously.

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

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

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

2 is a cross-sectional view of one embodiment of the Chanel company manufactured by the present invention,

3 is a cross-sectional view of one embodiment of the Chanel company manufactured 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 method for producing superabsorbent Chanel yarn comprising 2 to 4 bone adverbs which are included as weft yarns in a space formed by crossing the screens, wherein non-fused yarns are used as the screening yarns, and two or more synthetic fibers are used as the adverbs. Weaving step of weaving the screening and adverbs while including at least one composite fiber; A spinning step of cutting the adverbs of the fabric obtained in the weaving step and spinning them with Chanel yarn; It provides a manufacturing method of superabsorbent Chanel yarn comprising a processing step of expressing the composite fiber in a microfiber while reducing the Chanel yarn obtained in the spinning step.

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

In Fig. 1 an embodiment of a super absorbent Chanel yarn made in accordance with the present invention is shown. The Chanel yarn of the present invention 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, which is designed such that the composite fiber is divided into microfiber yarns during the weight loss processing in the processing step after weaving with the screening 210 to form a janggu shape so as not to fall out from the screening 210. It became.

As the screening used in the production method of the present invention, false twisted yarn of synthetic fiber is used, and preferably, it does not correspond to low melting point synthetic fiber (hereinafter referred to as 'non-fused yarn'). In the present invention, the 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 adverbs in a dyeing process, but is not preferable because it hardens the fabric and worsens the texture. .

The disadvantage of loosening the adverb by using non-fused yarn in the manufacturing method of the present invention can be compensated by carrying out the weight loss prior to the secondary weaving process as described below, and further, basic two-screen examination In addition, it can be supplemented by adding a third examination of the role of fixing adverbs.

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

In the present invention, the screening is used as a warp at the time of weaving for the production of Chanel, and serves to fix the weft yarn. More preferably, the screening is configured by adding a third screening to the basic screening. It is possible. 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. 2 and 3 embodying a preferred embodiment of the present invention, FIG. 2 is a top and bottom of each oval of the three adverbs 350 fixed by the first examination 310 and the second examination 310. As shown in Fig. 3 is a cross-sectional view of the Chanel yarn of the structure interlocking while the third examination (380) squeezes, and the third examination (480) squeezes up and down the two of the four adverbs (450) The cross section of the Chanel yarn of the structure is shown. In addition to the Chanel yarn in the weaving shown in the drawing above, three adverbs are divided into 2 ol-1 ols, and a third judicial branch is divided into two ol-1 ol-1 ols. Of course, the above and below implementations are possible.

The adverb used in the present invention may include one or more composite fibers in which two or more synthetic fibers are composite spun. The composite fiber is divided by alkaline weight reduction processing to make microfiber, and after the weight loss, the volume becomes bulky, and the voids increase to have high absorbency, which is more firmly fixed by the screening, and can be expressed to have a soft touch as microfiber. 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 yarns 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 of the present invention, the adverbs form a pile and spread in a janggu shape centering on the screening after division, so that the fixing by the screening can be more sure.

As described above, the Chanel yarn 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 high-quality appearance and excellent absorbency, and suppresses the occurrence of debris such as a lint. It is possible to manufacture a super absorbent and high quality material that can be.

In the manufacturing method of the Chanel yarn of the present invention, as described above, weaving is preferably performed using the screening and adverging yarns as warp and weft yarns (weaving step), and are equally spaced parallel to each screening (ie, the warp direction). After cutting the adverb with, it is possible to produce a Chanel yarn through a process such as burning it or folding the adverb (spinning step). Then, as an additional feature of the present invention, prior to the second weaving back into a woven fabric using the Chanel yarn spun above, the adverb is divided into microfiber by performing an alkali processing (loss) treatment simultaneously with or before dyeing. It is preferable to (processing step). The processing step of the present invention is a general weight loss to alkaline processing step, the composite fiber used as the adverb is expressed as a microfiber through this division process, the microfiber gap is opened and the adverb is spread in the janggu shape, Fixation can be increased.

In addition, after the second weaving step, further reduction or / and dyeing step may be further promoted to further divide the microfiber.

After that, it is possible to use as a product through various secondary weaving steps depending on the use by using the Chanel yarn manufactured according to the manufacturing method of the present invention. For example, a variety of tissues, such as the basic weave such as plain weave, twill, runner weave and deformed tissue can be made of a fabric having a high-quality appearance and excellent absorbency, weaving into single or double weave is also optional.

Chanel chair manufactured according to the present invention is formed into a more dense structure after a processing step to form a stable form, so that even in the weaving of general fabrics and multi-layer structure, the pile does not fall out by mechanical friction, also formed Chanel chair Nevertheless, it is possible to knit in the form of a knitted fabric can be manufactured in a variety of elastic products. Knitting fabric thus produced 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.
