Description

Suede-like Microfilament Textile Product Processed by Weight Reduction and Burn-out and Method of Manufacturing Equation}

The present invention relates to a suede-like microfiber knitted fabric that is two-tone and a sense of volume differently provided for various uses such as furniture decoration or differentiated clothing. More specifically, the present invention is a suede-like microfiber warp knitted fabric which is two-tone and a sense of volume differently provided to be used for various purposes such as furniture decoration or differentiated clothing through a microfiber reduction process and a differentiation burn-out process. It is about circular knitting. The present invention also includes a suede-like microfiber knitting method according to the present invention.

The present invention performs a burnout process for synthetic fibers that can be miniaturized through a weight loss process to give a certain volume feeling between burned out and unburned parts and at the same time selective burn through adjusting the concentration of alkali during burnout process. Similar to the process of quickly reducing the usable polyester in the general weight loss process, the two-tone effect of color due to the unique volume feeling and selective weight reduction effect of suede-like remains in the burned out part by the selective action of alkali in the burnout process The present invention relates to a burned out suede-like microfiber fabric which can be expressed simultaneously.

In the manufacture of suede-like knitted fabrics, techniques for producing suede with a more natural suede feel using microfiber have been developed, and related technologies are continuously developed in terms of touch, color, and process improvement.

In general, a method of manufacturing a knitted suede is made of extractable, rectangular, split, or island-in-the-sea composite fiber yarns and general synthetic fibers as light warp yarns, or a knitted fabric to reduce composite fibers. There is a method for miniaturizing and raising or buffing the microfibers, and through the process of transfer printing or foil processing for the post-processing of these products to increase the completeness of the suede products. Suede fabrics are often used in combination with thick fur to make garments. The post-processing of these products provides a variety of forms of two-tones or patterns through a single suede product in various forms, such as transfer printing, polyurethane and foil processing.

However, although the suede post-processing method manufactured by the conventional method as described above can provide various patterns, it is difficult to maintain the suede feeling in the part to which the natural two-tone effect or the uneven shape volume is given while giving the volume feeling. It is a disadvantage. Since transfer printing or foil processing is performed directly on the suede surface, there is a difficulty in halting the effect of natural brushing.

Therefore, the present inventors have developed the burned out suede-like microfiber knit fabric of the present invention which gives the color two-tone effect by burnout while retaining the uneven form of volume and natural suede surface appearance which cannot be expressed in the prior art as described above. It is early.

The present invention is the portion that is not removed and the portion removed by the burnout through the suede process after the knitted fabric made of only the seaweed yarn or split yarn or knitted yarn composed of seaweed yarn or split yarn and polyester-based high shrink yarn The present invention relates to a burned-out suede-like microfiber knit fabric which naturally gives a two-tone effect to the liver and allows the burnout to be differentiated even in a portion removed by the burnout, thereby giving a sense of volume and a suede feeling naturally given a two-tone effect.

It is an object of the present invention to provide a burned out new suede-like microfiber knit that gives a color two-tone effect by burnout while retaining a voluminous and natural suede surface appearance in the form of unevenness that cannot be expressed in the prior art.

Another object of the present invention is to remove the portion and removed by the burnout through the suede process after the knit fabric consisting of yarns or split yarns or knitted yarn consisting of yarns or split yarns and polyester-based high shrink yarn In order to provide a new burned out suede-like microfiber fabric that naturally expresses the two-tone effect between parts that are not, and makes the burn-out differentiated even in the part removed by the burnout, and gives a sense of volume and suede that is naturally given the two-tone effect. will be.

It is yet another object of the present invention to provide a new method for producing a burned out new suede-like microfiber knit that gives a color two-tone effect by burnout while retaining the uneven shape of volume and natural suede surface appearance.

The above and other objects of the present invention can be achieved by the present invention described in detail below.

Burned out suede-like microfiber knit according to the present invention is divided into warp knitted and circular knitted.

The warp knitted fabric is made of polyester island-in-the-sea yarn, polyester-based split composite yarn, PTT island-in-the-sea yarn or nylon island-in-the-sea yarn (hereinafter referred to as “warp knitting yarn 1”) as the surface yarn, and polyester-based yarn and nylon-based yarn as the back yarn. Or use a PTT type yarns. The surface yarn of the warp knitted fabric is interlaced between a polyester-based island-in-the-sea yarn, a polyester-based split composite yarn, a PTT island-in-the-sea yarn, and a nylon island-in-the-sea yarn and a high shrinkage polyester filament (hereinafter referred to as “warp yarn 2”). ) Can be used.

The surface yarns of the warp knitted fabric are composed of an eluting component and a fiber forming component, and after elution, the single yarn fineness is preferably 0.05 to 0.3 denier, and the back yarn is preferably 1 to 3 denier.

After knitting the warp yarn using the surface yarn and the back side yarn, and in the case of warp knitting yarn 1, the knitted dough is first brushed (stapped) and thermally set at 170 to 180 ° C. to determine the width of the final product, followed by excellent daylight fastness. After dyeing for 40 to 60 minutes at 130 ° C. with a disperse dye, it is washed with water and dried by heat setting at 160 ° to 170 ° C. again.

The disperse dyes used at this time are used to select a dye having excellent daylight fastness. The reason is that the part to be dyed is a usable polyester part, and the usable polyester uses a high daylight disperse dye to prevent this because the dye is easier to dislodge than the general polyester component due to heat and physical friction.

The brushed and dyed setting paper thus prepared is put into a burnout process. In the burnout process, the most important thing is to adjust the concentration of alkali. It is important to remove only the part of the usable polyester of the burned out part of the yarn, so that the burned-out part is not lost, but it is miniaturized by the alkali and causes the suede effect to be expressed. to be.

The burn composition and the amount of alkali used in the burnout process are prepared as follows. The paste is an aluminum silicate-containing powder, especially when used in polyester yarns, which can prevent chemical bleeding, and thus has the advantage that the burned out boundary is clean. In the coating composition, 12 to 24% by weight, 5 to 10% by weight of urea, 1 to 2% by weight of antifoaming agent, and 60 to 85% by weight of water are prepared, and the most important role here is the commercially available 38% liquid caustic soda And 98% powdered caustic soda is mixed in a 3: 1 weight ratio to be used in a mixing ratio of 20 to 80 wt%. The mixed solution was rinsed in a gravure method and steamed at 170 to 180 ° C. for 10 to 15 minutes at a normal temperature in a steamer. Do The finished product is cleaned through the late hair process, and then tenterized to a temperature of 160 to 170 ° C. to finally produce a burned-out suede microfiber fabric.

When warp knitting yarn 2 is used as the surface yarn in warp knitted fabrics, unlike warp knitting yarn 1, the surface yarn is not raised first. The reason is that both warp yarn 2 is interlaced with high shrink yarn, so if you brush it without heat shrinkage, you will feel rough texture on the surface with almost 3 denier yarns. Because. At this time, the warp knitted dough is first dyed for 40 to 60 minutes at 130 ℃ with a disperse dye and then washed with water, then dried by heat setting to 160 ~ 170 ℃.

The disperse dyes used at this time are used to select a dye having excellent daylight fastness. This is for the same reason as in the case of using the warp yarn 1. After dyeing, brushed and dried warp knitted paper heat set again to 160 ~ 170 ℃ to prepare a burnout.

The burnout process is performed similarly to the warp knitted yarn 1 mentioned above. The warp knitted product that has undergone a pre-dyeing process using warp knitted yarn 2 as a surface yarn can obtain a product having a weight increase of 30% or more based on the width of the same product compared to the warp knitted yarn 1 product.

The burned-out suede-like microfiber knit fabric is characterized in that the finished product after the burnout is cleaned and then tentatively treated at a temperature of 160 to 170 ° C.

In the case of circular knitted fabrics, one selected from polyester-based island-in-the-sea yarn, polyester-based split composite yarn, PTT island-in-the-sea yarn, and nylon island-in-the-sea yarn and interlaced (interlaced) high shrinkage polyester-based filament (hereinafter referred to as “circular yarn 1 ”). (The warp knitting yarn 2 in the warp knit and the circular knit yarn 1 in the round knit are the same)

The polyester-based island-in-the-sea yarn, polyester-based split composite yarn, PTT island-in-the-sea yarn, and nylon island-in-the-sea yarn are composed of an eluting component and a fiber forming component, and the single yarn fineness after elution is preferably 0.05 to 0.3 denier, and the high shrink polyester It is preferable that a system filament has a non-shrinkage rate of 24 to 45%.

The yarn is knitted into a circular knitted tissue that can be raised, and then treated in a continuous pretreatment at a temperature of 95 to 98 ° C. for 5 to 10 minutes to allow the circular knitted fabric to shrink and refine. The pre-processed circular knitted fabric is tenterized and dried at a temperature of 170 to 180 ° C. after opening according to the opening line.

The circular knitted fabric prepared above is mixed with hot and caustic soda preparation as described in the burnout process described in the warp knitted fabric, and then subjected to inner treatment for burnout, followed by steaming and washing and drying.

The burned out circular knitted fabric is brushed, disperse dye dyeing, and tenter heat treatment to prepare a finally burned out suede-like microfiber knit fabric.

In the case of the circular knitting structure which can distinguish the surface and the back surface, the circular knitting yarn 1 is used as the surface yarn, and the polyester yarn having a single yarn fineness of 1 to 3 denier, nylon yarn or PTT yarn is used as the back yarn. .

After knitting the surface yarns and the backside yarns, after refining shrinkage treatment in a continuous pretreatment for 5 to 10 minutes at a temperature of 95 ~ 98 ℃, the circular knitted fabric is opened by a tenter treatment at a temperature of 170 ~ 180 ℃ after opening the opening line. The burnout process is the same as the circular knitted fabric consisting of only the surface, and after the burnout process, the brush is brushed 6 ~ 8 times in the brushing machine and once in the shaling machine, and the tenter treatment is performed at 160 ~ 170 ℃ and 130 with a high daylight dispersion dye. Dyeing at 40 ℃ for 60 minutes, washed with water, and then tenter treatment at a temperature of 160 ~ 170 ℃, sanding twice with # 180 ~ # 240 sand paper to prepare a microfiber suede-like knitted fabric product.

Hereinafter, the present invention will be described in detail.

As described above, the present invention can differentiate the knitted fabric due to the suede feeling of the burned out portion, which was not seen in the conventional burnout, and also does not proceed with the weight reduction process, and only the weight loss effect of the burnout part to the volume of the product. There are features that can be assigned. This smooth surface, volume, and two-tone effect make it possible to use it as an exterior material for high-quality furniture and to produce burned-out suede-like microfiber fabrics that can be used as differentiated clothing products.

Burned out suede-like microfiber knitted fabric of the present invention is a surface yarn composed of a dissolution component and a fiber-forming component, and after elution, a polyester island-in-the-sea yarn and a split composite yarn, a nylon island-in-the-sea yarn, having a single yarn fineness of 0.05 to 0.3 denier, And any one of PTT-based island-in-the-sea yarns (warp knitting yarn 1) or interlacing any one of the warp yarns 1 and the high shrink polyester filament (warp knitting yarn 2), Polyester yarns, nylon yarns or PTT yarns with a single yarn fineness of 1 to 3 denier are used. In addition, as the back yarn used for the double-sided product of the circular knitted fabric, a yarn having a single yarn fineness of 1 to 3 denier is used as a nylon-based yarn or a PTT yarn.

The present invention is a method of selectively removing only the usable polyester portion of the microfiber used as the surface yarn in the burnout process of the warp knitted and circular knitted fabric consisting of the yarn configuration as described above in the burned out portion that was not seen in the previous burnout process Burned out suede microfiber fabric characterized by giving a suede feeling and expressing a sense of volume and two-tone effect.

In the present invention, the fibers used for the surface yarns are polyester-based islands, polyester-based split composite yarns, nylon-based islands, or PTT-based islands, filaments composed of an eluting component and a fiber-forming component. In the case of the island-in-the-sea yarn, the polyester-based island-in-the-sea yarn or the polyester-based divided composite yarn is preferably a polyester-based resin as the island component and a copolymerized polyester-based resin having different solvent-soluble properties as the sea component. In the case of a polyester-based divided composite yarn, it is preferable to use a polyester-based resin as a component remaining after the division and to use a copolyester-based resin having different solvent soluble properties as a solvent. In the case of the nylon island-in-the-sea yarn, it is preferable to use nylon-based resin as the island component and co-polyester-based resin having easy solvent solubility as the sea component. In the case of the PTT-based island-in-the-sea yarn, it is preferable to use PTT-based resin as the island component and to use copolyester-based resin having easy solvent solubility as the sea component. It is important that all of the four components are easily dissolved in alkali during the burnout process or the post-process by using a copolyester-based resin which is easy to use as a solvent.

Among the yarns, the type of island-in-the-sea yarn is typically 0.05 to 0.3 denier and about 0.3 to 0.1 denier in the case of the island-in-the-sea island fineness after the co-polyester-based resin is eluted in the post-processing process. In the case of using the island-in-the-sea yarn as a product, the softness of the surface of the final product may give a texture similar to that of natural suede, and in the case of a split composite yarn, it is particularly preferable to make a feeling of aftertaste.

In the present invention, as the back side yarns, nylon and PTT-based general denier yarns of 1-3 denier class are used so as not to be damaged by alkali during the burnout process. In addition, general straight yarn of polyester 1 ~ 3 denier class is used as the back side yarn, which is used in the product which does not affect the back side yarn by precisely adjusting the alkali concentration in the burnout process.

High shrinkage interlaced yarns by air entanglement used for some warp knitted fabrics and whole circular knitted fabrics are preferably interlaced yarns interlaced (interlaced) with high shrinkage polyester filaments having a single yarn fineness of 1.0 to 3.0 denier. At this time, the polyester-based, nylon-based and PTT-based island-in-the-sea yarn or polyester-based split composite yarn should be in the state of stretch yarn.

The high shrink polyester filament used in the present invention shows the same physical properties as the normal yarns when knitted, but has a non-shrinkage ratio of 24 to 45% as the yarn showing the high shrinking properties when hot water is encountered in the refining and dyeing process. It is preferable to use retained filaments, which have a non-shrinkage ratio of more than twice that of ordinary polyester filaments, and are air-entangled with polyester-based, nylon-based and PTT-based island-in-the-sea seaweed yarns or split composite yarns for further reduction processing. By forming a natural loop by the difference between the degree of shrinkage and the polyester islands-in-the-sea yarn or split composite yarn, it is possible to give a sufficient feeling of feeling by increasing the volume, raising the brushing process and the suede effect of the knitted fabric is good.

In the present invention, in the case of warp knitted fabric, the surface yarn is composed of an eluting component and a fiber forming component, and is a polyester-based island-in-the-sea yarn having a single yarn fineness of 0.05 to 0.3 denier after elution, and has a basic composition of 50 to 110 denier and 24 to 72 filaments. The polyester-based split composite yarns are composed of 70-110 denier and 48-72 filaments, and the nylon-based islands and PTT-based islands have the same basic composition as the denier and filaments of polyester-based islands. cider. Any one of them is used as a surface yarn, and a polyester yarn having a single yarn fineness of 1 to 3 denier, a nylon yarn or a PTT yarn is used as the back yarn.

After knitting the warp yarn using the surface yarn and the backside yarn, the knitted dough is first raised 4 to 8 times, and the shaving treatment is performed once to even the surface, so that the length and state of raising the surface yarn are constant. The brushed shaving product thus prepared is thermally set by giving an overfeed of 10-20% to prevent the product from elongating at 170-180 ° C. to determine the width of the final product. Overfeeding is intended to keep the surface of the brushed surface evenly. If the surface of the brushed paper is kept fine at the first setting, the overfeed is not extended to the finished product.

Next, the prepared primary setting paper was dyed with 130 to 40 minutes at 130 ° C. with a disperse dye, washed with water, and dried by heat setting at 160 to 170 ° C. again. In the case of the product using the nylon-based island-in-the-sea yarn and the PTT-based island-in-the-sea yarn as the surface yarn, the components forming the island-in-the-sea yarn appearance are copolyester-based polyesters, which are then dyed in the same manner as the above-mentioned dispersion dyes. The disperse dyes used at this time are used to select a dye having excellent daylight fastness. The reason is that the part to be dyed is a usable polyester part, and the usable polyester uses a high daylight disperse dye to prevent this since the dye is more easily dislodged than the general polyester component due to heat and physical friction. The brushed and dyed setting paper thus prepared is put into a burnout process. In the burnout process, the most important thing is to adjust the concentration of alkali so that only the part of the usable polyester of the burned-out yarn is removed, not all the burned-out part is lost, but it is miniaturized by alkali and makes it show suede effect. to be.

The burn composition and the amount of alkali used in the burnout process are prepared as follows. The paste is an aluminum silicate-containing powder, especially when used in polyester yarns, which can prevent chemical bleeding, and thus has the advantage that the burned out boundary is clean. In the coating composition, 12 to 24% by weight, 5 to 10% by weight of urea, 1 to 2% by weight of antifoaming agent, and 60 to 85% by weight of water are prepared, and the most important role here is the commercially available 38% liquid caustic soda And 98% powdered caustic soda is mixed in a 3: 1 weight ratio to be used in a mixing ratio of 20-25 wt%. If 38% liquid caustic soda and 98% powder caustic soda are made higher than 3: 1 ratio, the caustic soda may be dissolved by alkali in the burned out part and it may dissolve even the island component. It is important to proceed, if the ratio of the liquid caustic soda is more than the above there is a side that is difficult to remove the sea component easily within a given time of the process. In addition, the caustic soda prepared in a liquid composition and powder caustic soda 3: 1 weight ratio is mixed and used in the gas composition at a ratio of 20 to 25% by weight. It is difficult, and in the case of more than 25%, since the island component is affected by alkali a lot, it is difficult to obtain the desired quality.

The mixed solution is drawn in the desired gravure method and subjected to steaming for 6 to 12 minutes at 170 to 180 ° C, which is a normal temperature in a steamer, and sufficient carbonization is difficult for 6 minutes or less, and after 12 minutes, It is necessary to keep time as it is mad. After the carbonized part is completely removed in the water washing process and the tenter treatment at a temperature of 160 ~ 170 ℃.

The finished product is cleaned after 3 ~ 6 times of brushing in the late hair process, and then finished by tentering at a temperature of 160 ~ 170 ℃. It divides into microfiber by the alkali used, and expresses the suede feeling of the state from which the dissolved component was removed.

By minimizing the burnout area for products that have been dyed before burnout, a significant color difference can be expressed between the existing part and the minute part. Depending on the type of yarn used, it will produce a two-tone effect of 30% or more. In other words, when the micronized part is light-colored, it is not burned out, and the non-micronized part is thickened to express a clear two-tone effect. The portion remaining unburned is the copolyester-based dyeing and brushed, it is easier to thicken compared to the dyeing of polyester or PTT, nylon-based dispersion and acid dyes of general coating components. This makes the two-tone effect more pronounced. The part which is not burned out should basically be a yarn structure which can feel a soft suede feeling to some extent without going through a weight loss process as the single yarn fineness is about 1 denier, and this invention makes this one of the main elements.

In the present invention, in the case of warp knitted fabric to express another effect of providing the surface yarn using a yarn containing polyester filament high shrink yarn, the surface yarn is composed of the eluting component and the fiber forming component described above and eluted It is a polyester-based island-in-the-sea yarn with a single yarn fineness of 0.05 ~ 0.3 denier, and is composed of 50 ~ 110 denia and 24 ~ 72 filament.Polyester divided composite yarn is a basic composition of 70 ~ 110 denia and 48 ~ 72 filament. Nylon-based islands and PTT-based islands have a non-shrinkage ratio of 24 to 45% with single yarn fineness of 1 to 3 deniers on each of the yarns having the basic composition of denia and filament in the same range as polyester-based islands. Interlaced high filament yarns with air entanglement are used as surface yarns, and single yarn fineness is 1-3 denier Use of polyester-based direct radiation, nylon-based direct radiation or direct radiation PTT system.

After knitting the warp yarn using the surface yarn and the backside yarn, the knitted dough is refined in a rapid dyeing machine at 98 ° C. for 20 minutes, washed with water, dyed with 130 to 40 ° C. for 40 minutes with a disperse dye, and washed again. Dry by heat setting to 170 ° C. At this time, give 10-15% overfeed so that the prestained paper is not stretched. Since the dyeing process is already shrinking, you can give less overfeed than the pre-raised warp knit. When polyester-based high shrink yarns and air-interlaced yarns are used on the surface, they must undergo a process corresponding to hydrothermal shrinkage before raising. Otherwise, when brushing the dough, high shrinkage is expressed on the surface and the shrinkage treatment is not properly performed in the hot water treatment process, and thus the effect of the use of high shrinkage is lost, and only the texture of the surface is reduced.

The pre-dyed setting paper is put into the raising process. The brush is brushed 4 to 8 times, and the length and condition of brushing of the surface yarn are constant by carrying out one-time shading treatment to even the surface. The brushed shaving product thus prepared is heat-set and put into the burnout process while being careful not to stretch the product at 160 to 170 ° C.

The process after the burnout process is the same as the application of the warp knitting process, and the deviation after burnout between the burned out portion and the unburned portion becomes more prominent only due to the high shrinkage used for the surface yarn. In other words, the sense of volume is remarkable, and the aftertaste of the product is increased.

In the present invention, in the circular knitted fabric, the polyester-based island-in-the-sea yarn composed of the elution component and the fiber forming component described in the warp knitted fabric and having a single yarn fineness of 0.05 to 0.3 denier after elution is a basic composition of 50 to 110 denier and 24 to 72 filaments. The polyester-based split composite yarn has a basic configuration of 70-110 denier and 48-72 filaments, and the nylon-based island-in-the-sea yarn and the PTT-based island-in-the-sea yarn have a basic configuration of denier and filament in the same range as the polyester-based island-in-the-sea yarn. Interlacing polyester-based filament high shrink yarns with a non-shrinkage ratio of 24 to 45% with single yarn fineness of 1 to 3 deniers on each yarn is interlaced with air entanglement. do.

In the case of circular knitted fabrics in which the surface and the back surface can be distinguished from the circular knitted fabric, the same yarn as the above is used as the surface yarn, and the polyester yarn having a single yarn fineness of 1 to 3 denier, a nylon yarn or a PTT yarn is used as the back yarn. Knitting using and then processing in a continuous pre-treatment for 5 to 10 minutes at a temperature of 95 ~ 98 ℃ to allow the circular knitted fabric to shrink and refine at the same time. The pre-processed circular knitted fabric is tenterized and dried at a temperature of 170 to 180 ° C. after opening according to the opening line.

The prepared circular knitted fabric is subjected to two different kinds of processes, the first of which is to burn out the prepared circular knitted fabric in the burnout process and proceeds the raising process. It is.

First, the process of raising after burnout is as follows. The pre-processed circular knitted fabric is put into the burnout process to carry out the burnout process, and the amount of the hot water and caustic soda is the same as the amount of the burned out portion used in the warp knitted fabric that gives suede feeling without being completely carbonized. Will be used. In the burnout process of the burnout process, 12-24% by weight, 5-10% by weight of urea, 1-2% by weight of antifoaming agent, 60-85% by weight of water are prepared, and the most important role of alkali is commercially available 38 % Liquid caustic soda and 98% powdered caustic soda are mixed in a ratio of 3: 1 by weight and used in a mixing ratio of 20-25 wt%. If 38% liquid caustic soda and 98% powder caustic soda are made higher than 3: 1 ratio, the caustic soda may be dissolved by alkali of burned out part and dissolve even the island component. It is important to proceed, if the ratio of the liquid caustic soda is more than the above there is a side that is difficult to remove the sea component easily within a given time of the process. In addition, the caustic soda prepared in a liquid composition and powder caustic soda 3: 1 weight ratio is mixed and used in the gas composition at a ratio of 20 to 25% by weight. It is difficult, and in the case of more than 25%, since the island component is affected by alkali a lot, it is difficult to obtain the desired quality. The mixed solution is drawn in the desired gravure method and subjected to steaming for 6 to 12 minutes at 170 to 180 ° C, which is a normal temperature in a steamer, and sufficient carbonization is difficult for 6 minutes or less, and after 12 minutes, It is important to follow the time as it will affect. After the carbonized part is completely removed in the water washing process and the tenter treatment at a temperature of 160 ~ 170 ℃. After the burnout process is completed, the shaving treatment is performed to even out the brushed surface after raising 6 to 8 times in the raising machine. After the tenter treatment at a temperature of 160 ~ 170 ℃, dyed for 40 to 60 minutes at 130 ℃ with a high daylight dispersion dye and washed with water, and then the tenter treatment at a temperature of 160 ~ 170 ℃ and sandpaper # 180 ~ # 240 Finish by sanding twice. The finished circular knitted fabric is expressed in the two-tone dyeing effect remarkably as in the warp knitted fabric, and according to the results of the burnout process, it is possible to obtain a product having an uneven pattern with a sense of volume.

In the second method, pre-set circular knitted fabrics are first brushed 4 to 8 times in a brushing machine, the surface is uniformly arranged in a shearing machine, and then the brushed circular knitted fabrics are put into the burnout process as described above. After completion of the burnout as described above, after dyeing 40-60 minutes at 130 ° C. with a high-day dispersion dye, wash with water, proceed to tenter at a temperature of 160-170 ° C. and sanding twice with sandpaper # 180? # 240. To complete. Proceed with the burnout process after the napping, there is a difference in the burnout depth, there is a characteristic that can be given to differentiate the sense of volume. It can be seen that the burnout process applied product of the raised circular knitted fabric is more noticeable after the burnout portion and the non-burned portion than the pretreated circular knitted fabric.

The yarns used in the present invention are both island-in-sea type and split type that can be miniaturized through a weight reduction process, and the polyester-based high shrink yarn interlaced with these yarns has an additional role to give a sense of volume of the knitted fabric, and It plays an important role in securing the density of the part removed by elasticity and weight loss through high shrinkage. Knit fabric manufactured through the combination of these yarns is used to burn out the pattern of irregularities, and then the burned-out part through the heating and washing process expresses the soft suede effect, and between the burned-out and unburned parts. After the burnout, the product with the two-tone effect due to the selective reduction effect of the burnout part is expressed, and the unused part in the case of the split type in which the yarn used is itself a 1 denier micro yarn. Proceed to the non-reduced, the part that is partly reduced by burnout and the part that is not burned out but the form of the yarn and the brushing process only have a two-tone effect more than 30%, and also has a differentiating effect on the volume. .

The invention will be further elucidated by the following examples which are set forth for illustrative purposes only and should not be construed as limiting or limiting the scope of protection of the present invention.

Example  One

The surface yarn is composed of eluting component and fiber forming component. After elution, we use polyester-based island-in-the-sea yarn with a single yarn fineness of 0.05 denier. 8 times brushed in mosquito, heat set at 180 ℃, disperse dye CI disperse dye 74 (CIDisperse Red 74), CI disperse dye blue 56 (CIDisperse Blue 56) It is dyed by color matching with three kinds of CI Disperse Yellow 54 (CI Disperse Yellow 54), washed with water and dried by heat setting at 170 ° C. Next, 20% by weight of urea, 8% by weight of urea, 1% by weight of antifoam, 80% by weight of water, and a 38% liquid caustic soda and 98% powdered caustic soda were mixed in a 3: 1 weight ratio. The mixed solution prepared by mixing at a weight% ratio was drawn in the gravure method, and steamed for 10 minutes at 170 ° C., which is a normal temperature in a steamer, and then the carbonized part was completely removed in a washing process, followed by tenter treatment at a temperature of 170 ° C. do. The finished product was again cleaned four times in a brushing machine, and the surface was once again cleaned, and then tenterized to a temperature of 160 ° C. to remove the copolyester of the elution component in the burned out portion of the yarn by caustic soda. The non-burned suede-like microfiber with the feeling of volume has a general suede feeling by raising, and the two-tone effect by the color difference of the ultra-fine fraction and the non-micronized part is expressed more than 40%. Could get the knitting.

Example  2

The interlaced polyester-based composite composite yarn with a final fineness of 0.2 denier and a single high-fiber polyester high shrink yarn (non-shrinkage ratio 40%) with a fraction of 70 deniers per meter were interlaced with 70 interlaced water per meter.
