Description

Fabric for photo printing with excellent fastness and manufacturing method thereof {Goods for photo print and manufacturing method

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. When left for a long time to feel the discomfort and increase in weight due to moisture absorption has a problem that suffers from inconvenience when using.

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 fabric are made of PET-based conjugate yarn (hereinafter referred to as PET-based composite yarn), a material that enables high-density weaving and innovatively improves moisture absorption and drying speed. To improve the hygroscopicity and drying performance of the moisture, and to give the yarn bulky to maximize the sensitivity to the skin, and to increase the mobility and moisture mobility like natural materials, bulky yarn Weaving is achieved through tissue design that increases the area where bulky yarns come into contact with the skin and maximizes the capillary effect.

Sports towels using PET-based composite yarns having the characteristics described above are rapidly increasing their frequency of use due to their excellent durability and high durability that does not deteriorate even after long-term use by using the characteristics of chemical fibers with excellent mechanical strength. Although it is becoming a trend, despite the superiority of its function, the fashion is weak and the diversification of the use is not advanced.

On the other hand, sports towels are used in the existing towel market structure, from user-centered consumption structure, to giveaways for events of various groups such as schools and companies, event items for expressing homogeneity of various meetings, and to present family gatherings such as weddings and sixtieth birthdays, Printed for brand marketing such as various events, giveaways, or company's promotional logos on the towel surface while changing to consumption structure such as gifts presented at opening of new establishments and prizes additionally given when purchasing various sporting goods. Consumption is a very important issue.

However, PET-based composite yarn products manufactured for existing sports towels have excellent moisture mobility, but the drying rate of moisture transferred from skin to fabric is slowed down by using PET-based yarns used in the center of the fabric. There is a problem that it is difficult to feel the cleanliness when repeated use, and despite the quick hygroscopic performance, when used repeatedly, the same unpleasant feeling as the towel used before.

In addition, the existing products are manufactured with a focus on the functionality of the product has the following problems in the photo printing, which is currently increasing the needs of users. First, the yarn used in the towel paper uses 100% P / N split type (polyester 80%, nylon 20%) composite yarn on both the print face and the back face. When the ink for printing penetrates into the nylon part, the disperse dye for PET, which expresses the color among the ink components, does not express vivid colors, and moves to the surface in contact with moisture such as washing or sweating to improve the fastness. There is a problem that the color is changed after washing by lowering.

Second, when the yarn with the bulky (bulky) property is used as the print side to maximize the moisture absorption of moisture, a lot of protrusions are formed on the surface, so the transfer print film used for printing is structural The graphics are not in close contact with the surface, and no clear graphics are obtained.

Third, contaminants easily penetrate into the micro phores part created by the formation of many protrusions on the surface of the towel, causing contamination. There is a problem of deterioration.

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, high clarity and excellent fastness It is an object of the present invention to provide a fabric for a photo print and a method of manufacturing the same, which can pursue fashion by implementing a photo print.

The present invention configured to achieve the above object is as follows. That is, the fabric for photo prints excellent in the fastness according to the present invention weaving the fabric with a warp constituting the center and the two sides of the three different types of yarns centered on each other, while twisting the twisted yarn (draw twist) draw twist)} PET-type cross-section yarns with 8 slit cross sections are used, and the weft yarns forming the surface among the weft yarns are all processed by the twisting method, so that the single yarn fineness with high dyeing and fastness to disperse dyes is 1 denier The following polyester microfiber (Polyester micro fiber) is used, the weft forming the back side of the main function of moisture absorption of the weft yarn is made of a configuration using a buckle (Puck N) -based composite yarn.

As described above, the PET-based mold cross-section yarns constituting the warp yarns are DTY-processed POY yarns having excellent moisture movement by capillary action.

At this time, during DTY processing of PET-based cross-section yarn, the temperature condition for improving bulkiness for maintaining excellent cross-section and improving dryness by maintaining the cross-section of the yarn is 1.65 to 1.75, and draw ratio is 1.65 to 1.75. , D / Y is preferably 1.86 to 2.07 and k-value is 0.87 to 1.1.

Meanwhile, in the above-described configuration, the weft forming the surface of the fabric is twisted on one strand of yarn in the S direction, and then set under a temperature condition of 100 to 120 ° C. to set the yarn as a core yarn. ), Then use the yarn of the other strand as the effect yarn, and twist it to some extent as the core yarn rotates in the opposite direction through the yarn in the Z direction. It is manufactured from the twisted yarns of bulky (Bulky) through the process of all twisted yarns to have a.

At this time, the bulkiness of the twisted yarn (Twisted yarn) described above is adjusted by varying the number of years in the S direction to be produced and the Z direction to be processed later (Effect). In addition, to obtain the bulky twisted yarn (Twisted yarn) suitable for the surface of the fabric to maintain the optimum sensitivity and color clarity, the S ratio of the S and Z lead is in the range of 1: 1.3 to 1.7 bulky ( Bulky) is good to be maintained in the range of 6 to 10%.

In the above-described configuration, the weft forming the back side of the fabric is processed in two stages using three strands of yarn, but the two strands of P / N-based split yarn having excellent hygroscopic performance are put in parallel to the buckle nozzles (Buckle nozzel) with different input ratios. However, the effect yarn of the high input cost surrounds the core yarn of the low input cost and forms a loop, and then this PET yarn is separated from the PET yarn again. Buckle nozzel) is processed to prevent loosening of the loop by squeezing into 1: 1.

In this case, 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 fabric for photo prints excellent in color fastness according to the present invention is twisted and twisted yarn (draw twisted) yarn-based cross-section PET having both 8-slit (slit) cross section yarns both through the twisting method Single yarn fineness with high dyeing and fastness to disperse dyes by processing, polyester microfibers of less than 1 denier and buckles. Consists of weaving the fabric to the two sides forming a weft.

In the above-described configuration, the PET-based cross-section yarn constituting the inclined yarn is DTY processed POY yarn having excellent water movement by capillary phenomenon, but it maintains the cross section of the yarn during the DTY processing of the PET-based cross-section cross-section to increase dry performance and express excellent sensitivity. To improve the bulkiness, the temperature conditions 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.

Then, the weft forming the surface of the fabric twisted one strand of yarn in the S direction (Twist), and then set (Setting) under a temperature condition of 100 ~ 120 ℃ 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 bulky property of twisted yarn is produced in S direction and Z direction trained after effect. It will be adjusted differently. At this time, to obtain the bulky twist yarn (Bulky) suitable for the surface of the fabric to maintain the optimum sensitivity and color clarity, the S ratio of S and Z edges in the range of 1: 1.3 to 1.7 bulky ( Bulky property can be maintained in the range of 6 to 10%.

On the other hand, the weft forming the back of the fabric produced by the method as described above is processed in two steps using three strands of yarn, but the buckle nozzle (Buckle nozzel) parallel to the two strands of P / N-based split yarn excellent in hygroscopic performance Different yarns are added to the input yarns, but the effect yarn of the higher input cost surrounds the core yarn of the lower input cost, forming a loop, and then another PET system separate from this yarn. The yarn is put back into the buckle nozzle (Buckle nozzel) 1: 1 and pressed together to prevent loosening of the loop, but the bulkiness of the weft forming the back of the fabric is 15% or more, and the loop ( The length of the loop is in the range of 15 to 20 mm and the number of loops is in the range of 14 to 30 / inch.

Hereinafter will be described in detail with respect to the fabric for excellent photo prints and a manufacturing method according to a preferred embodiment of the present invention.

Photo-printed fabric with excellent 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 twisted), all through the twisting method Single yarn fineness as a weft yarn that is dyed and has a high color fastness to disperse dyes by processing. Polyester microfiber of less than 1 denier and buckle is used as a weft yarn that forms the back surface with moisture absorption as its main function. It is woven using three kinds of yarns such as P / N composite yarn.

As described above, the fabric for excellent photo fastness according to the present invention composed of three kinds of different yarns is applied to the inclined portion by applying a PET-based cross-section yarn to prevent moisture in the fabric transferred from the skin due to the capillary effect. It quickly diffuses into many areas, allowing it to dry quickly.

In addition, the fabric for excellent photo fastness according to the present invention is a weft forming the surface of the fabric all yarns through the twisting method to dyeing and dye fastness for the disperse dyes single yarn fineness less than 1 denier polyester microfiber (Polyester micro By applying fiber, the appearance of vivid colors and durability for washing are improved.

In addition, the fabric for excellent photo fastness according to the present invention is a weft forming the back of the fabric by applying a P / N-based composite yarn improved moisture absorption function and quick drying function through the buckle (Buckle) processing It maximizes the contact area, effectively improving the mobility of moisture.

Referring to the fabric for photo prints excellent in color fastness according to the present invention in more detail. First of all, the present invention has excellent slit performance of the 8-slit (Slit) excellent in the moisture absorption and quick drying function in the inclined portion forming the center of the fabric, unlike the conventional method to improve the point that the conventional products have excellent hygroscopic performance but slow drying speed Moisture in the fabric transferred from the skin using a PET-based yarn with a cross section causes a capillary effect along the eight slits, causing the moisture in the fabric to quickly diffuse into a large area and diffuse with the surrounding fabric. The drying rate of the moisture in the towel was improved by using the principle of drying rapidly by the difference in moisture concentration.

In addition, the fabric for a photo print with excellent color fastness according to the present invention is that the technical defects appearing when printing conventional products is to use a P / N-based composite yarn on the surface of the fabric to accept the dye to implement a vivid color {The P / N composite yarn contains about 20% of nylon (nylon) inside the yarn. The nylon part (nylon part) can be printed by using a disperse dye when printing, but then dyes again by washing or friction. Is difficult to maintain vivid color because it easily escapes and causes problems in fastness} First of all, on the theoretical basis that a vivid color photo print is possible and a high fastness can be obtained only when the part of the nylon part is present. In the design of the fabric, we have two types of weft composition of the fabric so that the double face (Double) face: double-sided paper) and different materials on both sides.

In other words, the surface of the fabric is processed with 100% polyester yarns through the twisting method in order to express vivid colors and improve washing durability, so that the dyeing property is excellent and the color fastness to the disperse dyes is excellent. Buckle processed P / N composite yarn was used to improve the moisture absorption.

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 on 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. On the surface of the fabric, polyester microfibers with excellent dyeing and fastness to the disperse dyes were all processed by twisting method, and the back side where moisture absorption performance should be excellent. P / N-based composite yarn was used for buckle processing. 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. Since the DTY processing must maintain the cross section of the yarn and increase the drying performance while the bulky property should be good for the excellent sensitivity invention, the optimal conditions for setting it should be set. According to the test results, the drying performance and excellent bulky yarn were obtained under the following conditions.

In other words, the most stable yarns can be manufactured in the temperature range of yarn processing at 170 to 195 ° C, 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 wefts that can print and have excellent moisture absorption, the wefts forming the surface of the fabric have excellent dyeability to disperse dyes, and have high fastness and excellent sensitivity to express 100% polyester microfibers of 1 denier or less ( Polyester micro fiber) is used to make the towel paper's sensibility, and it can be manufactured by all yarn processing to increase the bulkiness of yarn, and to improve the adhesive strength of transfer paper.

As mentioned above, all-twist yarn is a variation of twist yarn manufacturing technique, and yarns produced by a general twist method are twisted in one direction of S and Z so that the yarn is not bulky. It is widely used as a manufacturing method of strong support and compact yarn (Compact yarn), the all-twist method applied in the present invention is a method for producing a bulky twist yarn (Twist yarn) using two strands of yarn in more detail In other words, first, twist one strand of yarn in the S direction and set it at 110 ° C., then turn the yarn into a core yarn, and then another strand of impact yarn (Effect yarn). When the yarn is twisted in the Z direction as the core yarn rotates in the opposite direction, the twist is slightly loosened as the core yarn is rotated in the opposite direction, thereby producing 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 using the Trial error method on the fabric for excellent photo fastness as the towel paper fabric of the present invention as described above, 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.

And, 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 P / N-based split yarns 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, the 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, so it is possible to buckle the PET-based yarn of one strand, which is a different yarn from the first manufactured yarn. P / N system as a back yarn which makes the sensibility of towel paper appear at the end of the process by preventing the loosening of the loop through compressing each other at 1: 1. Complete the composite 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 using two P / N-based split yarn and one strand pressed yarn (Press), the compression yarn also Unlike the general 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.

As described above, the processed yarn on the back side is designed so that capillary pressure is applied from the yarn stage so that sweat or moisture generated on the user's skin surface can be quickly absorbed into the fabric and diffused into the atmosphere. It can be used.

In the present invention, the moon was buckle (Buckle) processing with the all-twisted yarn using the PET-based P / N split yarn used on the back surface, the processing conditions are bulky (Bulky) To maximize the sensitivity and moisture absorption of the towel paper by maximizing the maximization of the number of buckle loops during yarn processing, and by increasing the height of the loop (loop) to maximize the bulkiness of the entire yarn do.

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 is slowed down, so users will be uncomfortable and must maintain 15% or more. Also, the longer the length of the loop, the better the sensitivity, but the better the quality, but the length of 20mm or more is difficult to manufacture due to the process characteristics of the buckle method, and the bulkiness of the yarn is maximized when the minimum length is maintained at least 15mm. 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.

Hereinafter, a photo print fabric excellent in color fastness according to the present invention will be described through Examples and Comparative Examples.

EXAMPLE

Prepared by DTY processing of PET-based moisture absorption quick-drying yarn 150/72 as a slope forming the center of the fabric, and preparing 100/192 polyester to be used for the surface of the fabric (print surface). Three kinds of yarns with different ratios of 1.0, 1.4, and 1.8) were manufactured so that the bulkiness was 4%, 8%, and 12%, and the yarns to be used for the back side were PET-based P / N split yarns and PET-based hygroscopic dry yarns. The buckle (Buckle) processing to produce three kinds of yarn 13%, 17%, 20% of the bulkiness to correspond to a 1: 1 to prepare three kinds of fabrics (Examples 1, 2, 3).

On the other hand, after preparing three kinds of fabric samples prepared as described above, and obtained a fabric of a similar structure in the market to make a comparative example 1, the sensitivity of the fabric, the sharpness of the print line, the sharpness of the color and Laundry fastness and the like were evaluated.

Color clarity Fast drying of the fabric Sensitivity of the fabric Color fastness Early 30 times 60 times 100 times Example 1 Great Great Bad Grade 5 Grade 5 Grade 5 Grade 4 Example 2 Great Great Great Grade 5 Grade 5 Grade 5 Grade 4 Example 3 Good Bad Great Grade 4 Grade 4 Level 3 Level 3 Comparative Example 1 Bad Bad Great Grade 4 Level 3 1st grade 1st grade

(The fabric of Example 1 is a fabric having a bulkiness of 4% and 13%, respectively, of the front and back wefts, and the fabric of Example 2 is a fabric having a bulkiness of 8% and 17%, respectively, of the front and back wefts. The fabric of Example 3 is 12% and 20% of the bulkiness of the surface and back weft, respectively.)

As can be seen from Table 1, when the bulkiness of the yarn used on the surface of the fabric is lowered, the printing state and the color fastness are excellent, but the sensitivity of the fabric is lowered, and the productability is lowered. It is clear that fastness of washing is deteriorated sharply due to lack of sharpness and quick drying of colors.

In addition, the conventional products on the market can be seen that in the case of Comparative Example 1, the sensitivity of the fabric is good, but the quick drying of the fabric is poor, there is a serious problem in terms of sharpness and color fastness as a print fabric.

As described above, the present invention optimizes the selection of yarn materials and the setting of the processing conditions of both yarn and buckle processing, which show the bulkiness of the optimal conditions, and the drying speed of moisture in the fabric is fast, and the photo printing is easy, while the durability and washfastness Was able to produce an excellent double face fabric.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

As described above, according to the present invention, a PET-based cross-section yarn as a warp forming a center having an eight-slit cross section, which is twisted and twisted (draw twisted), all yarns are distributed by yarn processing. Single yarn fineness as a weft yarn that forms a surface with high dyeability and fastness to dyes P / N system as a weft yarn forming a back surface mainly having polyester moisture fiber of less than 1 denier and moisture absorption processed by buckle By weaving towel paper using three kinds of yarns such as composite yarns, it is possible to manufacture fabrics that exhibit rapid drying performance while maintaining rapid moisture absorption function.

In addition, the present invention is a polyester-based single-sided yarn having an 8-slit (slit) cross-section and single yarn fine yarns processed by the twisting method all the moisture absorption of polyester microfiber (Polyester microfiber) and buckle processing of less than 1 denier By weaving towel paper using three kinds of yarns, such as a P / N-based composite yarn, which functions as a function, it is possible to produce a fabric having high clarity and excellent color fastness.
