Description

Towel fabric for photo printing excellent in color fastness and manufacturing method thereof

The present invention relates to a fabric for a photo print with excellent fastness and a method of manufacturing the same. More specifically, three kinds of polyester yarns having different physical properties are processed and woven by applying different construction methods to each other. The present invention relates to a fabric for photo printing and a method of manufacturing the same, which is capable of excellent color effects.

It is well known that towels made of cotton yarn used in homes are widely used because they are soft to the touch and excellent in absorbing moisture. However, if a lot of sweat is continuously discharged during intense sports activities or sports activities, the towel of the natural fiber absorbs moisture quickly, but it dries up easily and loses its function as a towel. Breeding accelerates, causing an unsanitary condition with a bad smell.

In addition, natural fiber has the disadvantage of being easily damaged when used for a long time due to its low mechanical properties due to its inherent physical properties, and has a weak point of durability, and also has a high process moisture content (15% for cotton) and a high humidity area. In the long time left uncomfortable due to the moisture absorption and the increase in weight, so there is a problem that you experience inconvenience during use.

Accordingly, a new concept of towel fabric has been developed and used to overcome the limitations of natural fiber towels while being suitable for the function of sports applications. Towels using this new concept of towel fabrics are PET-based split yarns (conjugate yarns), which are materials that enable high-density weaving and innovatively improve moisture absorption and drying speed. To improve hygroscopicity and dryness of moisture, and to give bulky yarn to yarn by maximizing sensitivity to skin, and to increase the mobility and moisture mobility like natural materials The bulky yarn is weaved through a tissue design that increases the area of contact with the skin and maximizes the capillary effect.

Sports towel using the PET-based conjugate yarn (PET-based composite yarn) having the characteristics as described above is characterized by high durability that does not deteriorate even after long-term use by using the characteristics of chemical fibers with excellent function and mechanical strength Therefore, the frequency of use is rapidly increasing.

Meanwhile, although recently developed sports towels using PET-based composite yarns have excellent functionality, they are currently underway due to their weakness in fashion due to problems such as insensitivity due to the characteristics of fabric weaving, implementation of various colors, and low color fastness. Towel market is not leading the trend. In other words, the current towel market structure is a user-centered consumption structure, and prizes for events of various groups such as schools and corporations, event supplies for expressing the homogeneity of various groups, and gifts for family gatherings such as marriage and sixtieth birthday, and opening of new businesses The consumption of prints for brand marketing such as various events, giveaways, or the company's promotional logo on the towel surface is very important as it changes to consumption structure such as gifts of gifts and gifts that are additionally presented when purchasing various sporting goods. It is a problem.

However, the moisture absorption and drying process of the sports towel manufactured by buckle processing (a kind of processing) of the existing PET composite yarn has superior performance compared to the existing cotton towel, but the surface sensitivity is reduced due to the characteristics of the buckle processing. Unclear graphics caused by surface irregularities in photo printing have become a factor in limiting the merits of these towels.

In addition, PET-based composite yarn products manufactured for existing sports towels have excellent mobility of moisture, but the sloped portion used in the center of the fabric uses PET-based general DTY yarn with a circular cross section. It is stagnant and there is a problem of not exhibiting fast drying performance, it is difficult to feel the cleanliness due to the slow drying speed when repeated use, and will feel unpleasant like the existing cotton towel when used for a long time.

When the above problems are summarized by element, it can be seen that there are the following problems. First, as a problem that the skin feels rough when it comes into contact with skin, sports towel fabric made of fabric using chemical fiber (PET-based composite yarn) buckles the yarn to express the texture of the surface area like the existing cotton towel. It is manufactured by the method of expressing the loop of yarn as much as possible. When the yarns supporting the loop are pressed during processing, the touch becomes hard and causes bad touch to the skin. to provide.

Secondly, the fastness is lowered due to the nylon (nylon) component present in the PET composite yarn used as the weft yarn. The yarn used for the towel paper is 100% P / N split type on both the print face and the back face. (Polyester 80%, Nylon 20%) Composite yarns are used, which have about 20% of the nylon part after the cross-section. Therefore, when the ink for printing penetrates into this nylon part, not only the vivid color can be expressed, but also the ink leaves the fiber again when water or wet contact, such as washing or sweating, causes color contamination or discoloration to other fibers, causing contamination. There is a problem that the color line is damaged because the color fastness is lowered and the color changes after washing within 10 times.

Third, because of the inaccuracy of the graphic due to the many protrusions constituting the fabric surface, the buckle processing with the bulky property is used as the printing surface to maximize moisture hygroscopicity. Photo print film used to adhere to the surface of the fabric close to the printing is not possible to obtain clear graphics.

Due to the problems described above, although the sports towel according to the prior art has excellent hygroscopic function, the above-mentioned various uses due to the deterioration of the hard sensitivity and the quick drying and the difficulty of printing are emotionally hard. We are having difficulty using furnace.

The present invention has been proposed to solve all the problems of the prior art, focusing on the problems of the towel according to the prior art, while maintaining the existing fast moisture absorption function to enhance the fast drying functionality, excellent sensitivity and sharpness It is an object of the present invention to provide a towel fabric for a photo print and a method of manufacturing the same, which can pursue fashion by implementing a photo print having excellent fastness.

The present invention configured to achieve the above object is as follows. In other words, in the towel fabric for photo prints excellent in color fastness according to the present invention is a towel fabric for photo prints of the structure weaving the fabric as a weft forming the slope and the surface and the back and the back to form a center using three different kinds of yarn, The center of the inclined yarn is twisted and twisted (draw twisted) PET-based sectional cross-section yarn with 8 slit cross section is used by DTY processing, and the weft of the surface forming the printed surface among the weft yarn is 15 Designed with a long pile of ～ 20mm, it is cut and knitted, but applied yarn is twisted to draw 100% PET microfiber of 0.3 denier or less with high dyeing and fastness to disperse dyes. : Pull and twist yarns) and DTY after interacing, using yarn, and moisture absorption of the weft yarn as the main function The weft forming the back is woven fabric using P / N-based composite yarn which buckle-processed three strands of yarn in two stages, but the woven fabric is put into the raising process to make the surface (print surface) of the fabric. After 4 ~ 8 times of brushing, sheering is done.

PET-based mold cross-section yarn constituting the above-mentioned inclined DTY processing POY yarn which has excellent water movement by capillary phenomenon, while maintaining the cross-section of the yarn during DTY processing of PET-based mold cross-section cross-section to improve dry performance and express excellent sensitivity. The temperature conditions for improving the bulkiness are 170 to 195 ° C, the draw ratio is 1.65 to 1.75, the D / Y is 1.86 to 2.07 and the k-value is 0.87 to 1.1.

The weft forming the surface of the above-described fabric is twisted one strand of yarn in the S direction (Twist) and then set under a temperature condition of 100 ~ 120 ℃ to set the yarn as a core yarn (Core yarn), All yarns that have a bulky loosening to some extent as the core yarn rotates in the opposite direction through the yarns in the Z direction using the yarn of the other strand as the effect yarn. It is manufactured from bulky twisted yarn after the process of processing.

The bulkyness of the twisted yarn described above is controlled by varying the number of softenings in the S direction to be produced and the Z direction afterwards processed into an impact, but the bulky twisted yarn suitable for the surface of the fabric. In order to maintain optimal sensitivity and color clarity, the continuous shooting ratio of S and Z is 1: 1.3 to 1.7 so that the bulkiness can be maintained in the range of 6 to 10%. Can be done.

The entanglement strength of the weft forming the above-mentioned surface is 1.6g <entanglement strength <3.2g, the number of entanglement is composed of seven sums satisfying the conditions of 24ea / m <entanglement <60ea / m.

The weft forming the back of the fabric is processed in two stages using three strands of yarn, but the two strands of P / N-based composite yarn with excellent hygroscopicity are put in parallel to the buckle nozzle (Buckle nozzel) with different input ratios. Effect yarns at the higher feed rate wrap around the core yarn at the lower feed rate and form a loop, and then buckle this yarn and other P / N-based presses again. It is made of a configuration that is processed to prevent the loosening of the loop (Loop) by putting in a 1: 1 in the nozzle (Buckle nozzel) to compress each other.

The bulkiness of the weft forming the back of the fabric is 15% or more, the length of the loop (Loop) is in the range of 15 to 20mm and the number of loops is in the range of 14 to 30 / inch.

On the other hand, the manufacturing method of the towel fabric for photo prints excellent in color fastness according to the present invention through the PET-based mold cross-section yarn having an eight-slit cross section (draw twist) twisted and pulled through both yarn twisting method Single yarn fineness with high dyeing and fastness to disperse dyes, using yarn of less than 0.3 denier, but with draw twist for better napping, and DTY after interacing Weaving the fabric through three different types of 100% PET micro yarn (homogeneous polyester micro fiber) and buckle processed P / N-based composite yarns, but the surface of the PET-based cross-section cross section is a slope Weaving fabric using 100% PET micro yarn as a weft forming yarn and P / N composite yarn as the weft forming a back side, and putting the woven fabric into the raising process After the surface of the fabric over a 4-8 conference, brushed processing eojinda achieve a configuration that produced by shearing (shearing).

PET-based mold cross-section yarn constituting the aforementioned inclination DTY processing POY yarn excellent in the movement of moisture by capillary phenomenon, while maintaining the cross-section of the yarn during DTY processing of PET-based mold cross-section cross-section to increase the drying performance while expressing excellent sensitivity The temperature conditions for improving the bulkiness are 170 to 195 ° C, the draw ratio is 1.65 to 1.75, the D / Y is 1.86 to 2.07 and the k-value is 0.87 to 1.1.

The weft forming the surface of the above-described fabric is twisted one strand of yarn in the S direction (Twist) and then set under a temperature condition of 100 ~ 120 ℃ to set the yarn as a core yarn (Core yarn), All yarns that have a bulky loosening to some extent as the core yarn rotates in the opposite direction through the yarns in the Z direction using the yarn of the other strand as the effect yarn. It is manufactured from bulky twisted yarn through the process of processing of the process, but the bulkyness of twisted yarn is different from the number of S-directions to be manufactured and the Z-direction afterwards processed into impact. It consists of the configuration to adjust.

In order to obtain the bulky twisted yarn suitable for the surface of the fabric described above, and to maintain the optimum sensitivity and color clarity, the S- and Z-lead firing ratios are in the range of 1: 1.3 to 1.7 to be bulky ( Bulky) is composed of one configuration to be maintained in the range of 6 to 10%.

The weft forming the back of the fabric is processed in two stages using three strands of yarn, but the two strands of P / N-based composite yarn with excellent hygroscopic ability are put in parallel to the buckle nozzle (Buckle nozzel) with different input costs. The high impact yarn wraps around the core yarn at the lower feed rate and forms a loop.Then, the yarn is buckled again with another P / N-based compressed yarn. (Buckle nozzel) is processed to prevent loosening of the loops by squeezing into 1: 1, but the bulkiness of the weft forming the back side of the fabric is 15% or more, the length of the loop The range of 15-20mm and the number of loops is in the range of 14-30 pieces / inch.

Hereinafter will be described in detail with respect to a towel fabric for photo printing excellent in color fastness and a method for manufacturing the same according to an embodiment of the present invention.

Towel fabric for photo printing excellent in color fastness according to the present invention is a PET-based cross-sectional yarn as a warp forming a center having an eight-slit cross-section twisted and twisted (draw twist), both twisted yarn method As a weft yarn with a dyeing and high color fastness to the disperse dyes, which is processed through the yarns, the back surface is mainly made of 100% PET microfibers with less than 0.3 denier and moisture absorption processed by buckle. It is woven using three kinds of yarns, such as P / N-based composite yarn as a weft forming a yarn.

As described above, the towel fabric for photo printing excellent in color fastness according to the present invention consisting of three kinds of yarns is applied to the capillary effect by applying a PET-based cross-section yarn to the inclined portion. It quickly diffused to a large area (Diffusion) to be able to dry quickly.

In addition, the towel fabric for photo prints excellent in color fastness according to the present invention is a weft forming the surface of the fabric, all processed through the twisting method, 100% PET micro yarn of less than 0.3 denier single yarn fineness high dyeing and fastness to the dispersion dye By applying (homogeneous polyester micro fiber), the appearance of vivid color and the durability for washing are improved, and the weft forming the back side of the fabric improves the moisture absorption function and quick drying function through the buckle processing. By applying N-based composite yarn, the area in contact with the skin is maximized to effectively improve the mobility of moisture.

Referring to the towel fabric for photo prints excellent in color fastness according to the present invention in more detail. First, the present invention is to build a surface to raise the surface of the fabric well using a pile fabric manufacturing technique that has not been applied in order to improve the bad emotion that is a problem of the conventional sports towel, raising and shearing this part It is designed to maximize the contact surface with skin by making soft yarn on the surface of fabric to make a soft feeling.

In particular, this brushed surface used as a surface is used as a print surface by users, so 100% PET micro yarn is used to maintain fastness in print and to obtain clear graphics. Weave by At this time, the surface should be improved through the brushing and shearing process to improve the sensitivity and secure print fastness, so that the density of tissue in the fabric should be built in accordance with the conditions of brushing process. In the present invention, the density condition of the weft forming the surface is 32T / inch <surface weft density <50T / inch.

If the weft density is 32T / inch or less under the conditions as described above, the weft of the back surface breaks during the raising process, and the tissue of the fabric is disturbed. The illustration is too high to get the desired soft handle. In addition, at a high density of 50T / inch or higher, the moisture absorption speed in the fabric is significantly reduced due to the high aftertaste and the high density, and the deterioration of the moisture absorption quick-drying function, which is a unique function of the towel, appears clearly.

On the other hand, the towel fabric for photo prints excellent in color fastness according to the present invention, unlike the conventional method in order to improve the drying performance of the towel fabric 8 slits excellent in moisture absorption and quick drying function in the inclined portion forming the center of the fabric Moisture in the fabric transferred from the skin using a PET-based cross-section yarn having a cross-section of the film causes a capillary effect along the eight slits, causing the moisture in the fabric to quickly diffuse into a large area. The drying speed of the water in the towel was improved by using the principle of drying rapidly by the difference in moisture concentration with the surroundings.

In addition, the towel fabric for photo printing excellent in the fastness according to the present invention is to use a P / N-based composite yarn on the surface of the fabric that the technical defects appearing when printing conventional products to realize a vivid color by accepting the dye {P / N composite yarn contains about 20% of nylon (nylon) inside the yarn, which is printed by using disperse dyes in printing, but then washed or rubbed It is difficult to maintain vivid colors because dyes easily come out and cause problems with fastness}. The theoretical basis that clear color photo print is possible and high fastness can be obtained only when the nylon part is removed. In the design of the fabric, the double-faced fabric has two types of weft configuration. Double face was used and different materials were used on both sides.

In other words, the surface forming the printed surface of the fabric is changed to a filed structure in order to enable printing of high sensitivity and favorable to the emotional part, but it is used instead of 100% PET micro yarn (homogeneous polyester micro fiber) as the applied yarn. In addition, since the back surface having the moisture absorption function as the main function is not the print surface, P / N composite yarn which is more advantageous in hygroscopicity was used. In other words, we designed and applied a double-layer fabric fabric with different weaving methods and different yarns on the double side.

As described above, it can be seen that all three kinds of yarns used in the technology according to the present invention. At this time, since these yarns must exhibit different performance in the fabric, the yarn must be manufactured by selecting a processing method suitable for each performance.

First of all, we used a draw twist of recently developed PET-based cross-section yarn in the inclined part to grab the weft of both sides of the towel function in the towel fabric and quickly dry the moisture transferred from these sides. The part that should be printed on the surface of the fabric is draw twist and interacing so that the brushing process is advantageous for 100% PET microfiber (dymogeneous polyester microfiber) with excellent dyeing and fastness to disperse dyes. Processed and applied, P / N-based composite yarn was buckle (Buckle) was used on the back of the moisture absorption performance should be excellent. Looking at this in detail.

First, the PET-based sectional cross-section yarn with excellent quick-drying property as a slope forming the center of the fabric was composed of eight slits (Slit) of the yarn cross section, and POY yarn, which has excellent movement of moisture due to capillary action, was used by DTY processing. At this time, the DTY processing must maintain the cross section of the yarn, while improving the drying performance, the bulky (Bulky) property should be good for the invention of excellent sensitivity, so the optimal conditions to meet this should be set in consideration of the characteristics of the yarn in the present invention The test results showed that drying performance and excellent bulky yarns were obtained under the following conditions.

In other words, the most stable yarn can be manufactured in the temperature range of yarn yarn processing at 170 to 195 ℃, draw ratio of 1.65 to 1.75, D / Y of 1.86 to 2.07, and k-value of 0.87 to 1.1. there was. At this time, the yarn to be manufactured should not have the phenomenon of slit (slit) due to high temperature and excessive friction during processing, so the high temperature and excessive D / Y increase can increase the bulkiness of the yarn, Care should be taken because the drying performance is reduced.

On the other hand, of the two types of weft that can be printed and excellent in moisture absorption, the weft which forms the surface as the printing surface of the fabric is excellent in dyeing to disperse dyes, and 100% of 0.3 denier or less in order to express high fastness and excellent sensitivity. PET micro yarn (homogeneous polyester micro fiber) was used. At this time, in order to maximize the soft sensibility as a towel paper, the yarn is put into the DTY process is manufactured through the twisting all the processing can increase the bulkiness (Bulky) of the yarn.

As mentioned above, all-twist yarn is a twisting technique of twist yarn manufacturing technique. The yarn manufactured by the general twist method is twisted in one direction of S and Z, so that the strength of the yarn is higher than the bulkiness of the yarn. It is widely used as a manufacturing technique for supporting and compact yarns. The all-twisting technique applied in the present invention is a method for producing a bulky twist yarn using two strands of yarn in more detail. To explain, first, twist one strand of yarn in the S direction and set it at 110 ° C., then use the yarn as a core yarn and then the other strand as an impact yarn. When the yarn is twisted in the Z direction, as the core yarn rotates in the opposite direction, the twist is slightly loosened and the bulk yarn is made into a bulky yarn suitable for toweling. In this case, in order to reduce or enlarge the bulky property, it is possible to control the bulky property by differentiating the number of years in the S direction which is initially manufactured and the number of years in the Z direction processed into the impact.

In order to obtain a bulky yarn suitable for the surface of the towel paper fabric, which is the fabric according to the present invention, the most suitable bulky in the ratio of S and Z is 1: 1.3 to 1.7 through several tests. It was confirmed that bulky property can be obtained. At this time, by emphasizing only the inherent sensitivity of the towel paper fabric, the fabric according to the present invention, only the bulkiness of the yarn is emphasized. It is most important to optimally set the bulkiness of yarns in the case of all twisted yarns because it is impossible to get a clear graphic line because it is not in close contact with each other.

As a result of the test of the towel fabric for photo print excellent as a towel paper fabric of the present invention as described above by applying the Trial error method, it was found that the most optimal sensitivity and color clarity were maintained under the following conditions.

That is, the most optimal sensitivity and color clarity are maintained when the bulky property is 6 to 10% and the S / Z firing ratio is 1.3 to 1.7. At this time, if the bulkiness of the yarn is lowered to 6% or less, the user's sensitivity is deteriorated, and the merchandise is inferior. In the bulkiness of 10% or more, the clarity of color deteriorates due to the adhesion of transfer paper and the relaxation of tissue. When the S / Z firing ratio is 1.3 or less, the bulkiness of the yarn becomes low, and color development as a towel paper is difficult. When the ratio exceeds 1.7, the bulkiness becomes high, and the adhesion of the transfer paper becomes worse when the photo print is difficult, so that it is difficult to obtain vivid colors.

On the other hand, as described above, in order to maximize the soft sensibility as a towel paper, the yarn is put into the DTY process to increase the bulkiness of the yarn. In this case, to increase the bulkiness, the twist during processing ( It is necessary to increase the twist ratio as much as possible, but if it is too high, the file may lie down or twist during weaving. Therefore, it is necessary to set the optimal condition to satisfy the conditions of the transferee.

In other words, it is essential to set a condition in which the file is not laid down or twisted and the file formation is excellent and the soft sensitivity can be maximized. In addition, when the prepared yarn is woven into the brushing process, it is necessary to maintain a high-density fabric surface unlike general plain weave in order for the brushing process to proceed smoothly. By adopting the DTY after interracing method, the 7-in-line process is applied to increase the thickness of the yarn by 7 times.

However, after forming the pile surface of the fabric surface through the yarn manufactured as described above, each air-fed yarn is raised and sheared again in order to ensure excellent sensitivity and sharpness of the print. Only after the process can be separated to obtain the soft handle (clear) and the graphic to be obtained in the present invention.

Therefore, the optimization of the conditions during the processing of the yarn that meets the conditions as described above is essential. To this end, various test results for optimizing the entanglement strength and the number of entangled yarn was found in the present invention satisfies both conditions under the following entanglement strength and entangled number. In other words, the entanglement strength was 1.6g to 3.2g, and the number of entanglements was 24ea / m to 60ea / m. This will be described in more detail as follows.

As can be seen from the experimental results as described above, when the yarn's entanglement strength is low, the pile formation is difficult, and the raising process is difficult, and when the yarn's entanglement strength is increased, the splitting of the yarn after raising and shearing becomes difficult. Since it is not possible to obtain the desired soft handle, it is important to optimize the yarn strength and the number of yarns. Therefore, as described above, when the entanglement strength is less than 1.6g, the pile formation is worsened, and when the entanglement is more than 3.2g, the division of the pile is not made, so setting of the entanglement strength in this section is very important.

In addition, when the number of entanglements is less than 24ea / m, the binding force between yarns is reduced and file entanglement or file relaxation occurs, so that a clear graphic line cannot be obtained. It appears that the irregularity of the handle (handle) according to the distal portion is required to set the appropriate range.

On the other hand, the production of the back yarn to express the sensitivity of the towel paper while excellent moisture absorption is as follows. P / N-based composite yarns are manufactured on the back of the fabric which has moisture absorption as its main function through the buckle processing, as in the prior art, and this processing method uses three strands of yarn unlike all the previous yarns. It is prepared in two steps.

First, two strands of P / N composite yarn having excellent hygroscopic performance are introduced into the buckle nozzle in parallel. If the input ratio is different, the lower input ratio becomes the core yarn, and the higher input ratio is used. The effect yarn becomes the effect yarn, and the effect yarn wraps around the core yarn to form a loop, which increases the bulkiness of the yarn and expresses the sensitivity suitable for the purpose of the towel paper. .

However, Yarn manufactured in this way does not go through a separate setting, so there is a problem such as loosening of the loop when used as a finished product. Therefore, one strand of P / N-based crimped yarn, which is separate from the primary yarn, is used. (press) is put back into the buckle nozzle (1: 1) by pressing them together to prevent loosening of the loop, and finally absorbs moisture on the back side while showing excellent moisture absorption. Complete P / N composite yarn as yarn.

P / N-based composite yarn used on the back of the fabric of the fabric according to the present invention as described above is threaded by using two strands of P / N-based composite yarn and one strand of pressed yarn (Press), Also, unlike the conventional DTY yarn used in the prior art, it was designed and applied to quickly move the moisture in the fabric by using a moisture absorption quick-drying yarn. In other words, the processed yarn on the back surface manufactured as described above allows the capillary pressurer to act a lot from the yarn stage so as to quickly absorb the sweat or moisture generated on the user's skin surface into the fabric and diffuse it into the atmosphere. It can be said that it was designed and used.

In the present invention, unlike all-twisted yarns in which PET-based P / N composite yarns were used on the back surface were used for buckling, at this time, unlike the yarns on the surface, the processing conditions maximize bulky properties. To increase the sensitivity of the towel paper and moisture absorbency, the number of buckle loops is maximized when yarn processing, and the height of the loop is maximized to maximize the bulkiness of the entire yarn.

In addition, the yarn processed by the method proposed in the technique according to the present invention was found to be the most ideal sensitivity and rapid movement of moisture when the following conditions are met. In other words, it is most ideal that the bulkiness is 15% or more, the loop length is 15-20 mm, and the number of loops is 14-30 pieces / inch. This will be described in more detail as follows.

First, when the bulkiness of the yarn is less than 15%, the drying speed of the moisture is fast, but the movement speed of the moisture from the skin surface to the fabric becomes slow, so that the user experiences inconvenience, so it must be maintained at least 15%. In addition, the longer the length of the loop (Loop), the better the sensitivity, but the better, but the length of 20mm or more is difficult to manufacture due to the process characteristics of the buckle (Buckle) method and at least 15mm to maintain the bulkiness of the yarn is maximized. In addition, the greater the number of loops, the greater the bulkiness of the yarn, but at 30 or more, the compressive strength of the crimp is lowered and the bond strength of the loop is weakened. Essence is too low and looking as a towel paper (Looking) is worse, there is a disadvantage that the commerciality is inferior.

Using the prepared yarns as described above, the density of the fabric in the fabric is set to a file by striking 46T with 350den / 1008 filament, and the back side is buckled with a P / N-based composite yarn for 320den / It is made of 144 filaments, and then flattened to 46T. Then, it is put into a brushing process, and the fabric surface is subjected to 8 times of brushing and shearing to prepare a fabric. As a result of measuring the handle and print performance of the fabric thus manufactured, it was possible to manufacture a fabric having excellent soft handle, clear graphics, and quick drying function.

Hereinafter, the towel fabric for photo prints excellent in the fastness according to the present invention will be described through Examples and Comparative Examples.

[Example]

The ramp for the fabric is prepared by DTY processing of PET based aero cool 75/36, and the yarn to be used as the weft of the fabric is the weft to be used for the surface. 100% PET micro yarn with 0.3 denier of single yarn (homogeneous polyester) micro fiber) prepared by processing 50/144 by DTY after interacing process conditions (Example 1: 20 ea, Example 2: 40 crush, Example 3: 60 crush) Weft yarn to be used in the PET-based P / N composite yarn buckle processing (loop number: 20ea) to be prepared and prepared under one condition.

Next, the weft yarn to be used for the warp and the back surface is fixed to one type by using the yarn prepared in advance, and the sample of Comparative Example 1 using the P / N-based composite yarn used on the back surface as the conventional product is used (sample ), The fabric of similar tissues on the market was obtained, and the sample of Comparative Example 2 was prepared. Then, three samples of the example were woven using the three types of surface wefts prepared above. The same process was carried out by applying the same to the raising and shearing process to complete the processing of the sample and the example sample of Comparative Examples 1 and 2, and then, to evaluate the influence of the raising process, Example 1 After the sample of the sample was processed 10 times in the raising process, the sample of Comparative Example 3 was made, and the sensitivity of the fabric, the sharpness of the print line, the sharpness of the color and the color fastness of the wash were as follows. Rate it Table 1 It is shown.

Color clarity Quick-drying of the fabric Sensitivity of the fabric Color fastness Early 30 times 60 times 100 times Example 1 Great Great usually Grade 5 Grade 5 Grade 5 Grade 4 Example 2 Great Great Great Grade 5 Grade 5 Grade 5 Grade 4 Example 3 Great Great Great Grade 5 Grade 5 Grade 5 Grade 4 Comparative Example 1 Bad Great Bad Level 3 Level 3 2nd class 2nd class Comparative Example 2 Bad Bad Bad Level 3 Level 3 2nd class 2nd class Comparative Example 3 usually Great usually Grade 5 Grade 4 Grade 4 Level 3
