Description

MANUFACTURING METHOD OF TOWEL TEXTILE FOR DIGITAL PHOTOPRINT}

The present invention relates to a method for manufacturing a towel fabric for digital photoprint, and more particularly, by processing two different polyester-based yarns and natural cotton yarns having different physical properties and weaving by combining them with a different method, The present invention relates to a manufacturing method of a towel fabric for digital photoprinting with improved color absorption, drying performance and washing fastness and improved moisture absorption and feel.

In general, 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 continually discharged during intense sports activities, the towel made of natural fiber absorbs quickly but is dry and loses its function as a towel easily, and the water-borne microorganisms multiply over time. It becomes unsanitary with odor.

In addition, natural fiber has a good touch, but due to the inherent physical and chemical properties of the fiber, the fiber has a weak durability such as wear and deformation of the fiber tissue over a long time, and also has a high moisture content (15 to 20% for cotton) When left in a high humidity area for a long time, the unpleasant feeling caused by moisture absorption and an increase in the weight of the product cause an inconvenience in 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. The characteristic of the towel using this new concept of towel fabric is that PET-based composite yarn, which is a material that enables high-density weaving and innovatively improves moisture absorption and drying speed, improves water absorption and drying performance, and touches skin. In order to maximize the sensitivity, the yarn is processed to give bulkiness to the yarn, and the bulky yarn increases the contact area with the skin to further increase the sensitivity and mobility of moisture like natural materials. In addition, a weaving method for maximizing the capillary effect in the fibrous tissue is performed.

Sports towel using PET-based composite yarn having the characteristics described above is rapidly increasing its frequency of use due to its excellent durability and high durability that does not deteriorate even when used for a long time using the characteristics of chemical fibers with excellent mechanical strength. It is becoming a trend.

However, 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 based on user-centered consumption structure, giveaways for events of various organizations such as schools and companies, event supplies for expressing the homogeneity of various meetings, gift of family gatherings such as marriage and sixtieth birthday, and new business establishments. With the change of consumption structure, such as gift giveaways and gifts that are additionally presented when purchasing various sporting goods, consumption behaviors for brand marketing such as various events, giveaways, or the company's promotional logo are emerging as an important topic on the towel surface.

In other words, the water absorption and drying process of the sports towel produced 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 deteriorated due to the characteristics of the buckle processing. And the unclear graphics caused by the irregularities in the fabric surface during photoprinting have become a factor in making these towels their commercially viable limits.

In addition, PET-based composite yarn products manufactured for conventional sports towels have excellent moisture mobility, but the sloped portion used in the center of the fabric is made of polyester-based general DTY (Draw textured yarn) yarn with a circular cross section. Moisture transferred to the fabric from the stagnation has a problem that does not exhibit a quick drying performance, the moisture drying rate is slow when repeated use, the cleanliness is reduced and if used for a long time, the same discomfort as the existing cotton towel.

In addition, PET composite yarns used as weft yarns use 100% P / N split type (Polyester 80%, Nylon 20%) composite yarns on both the surface and the back side. Leaves about 20%. Therefore, if the ink for printing penetrates into this nylon part, it will not be able to express vivid colors, and the ink will leave the fiber again when contacting with moisture such as washing or sweating, causing color contamination or discoloration to other fibers, causing contamination. There is a problem such that the graphics fastness is damaged after washing by lowering the wash fastness.

In addition, since the buckle processing with the bulky property is used as the print surface in order to maximize the hygroscopicity of moisture, the transfer paper used for printing is structurally fabricated due to the large number of protrusions forming the fabric surface. It is difficult to adhere well to the surface of the print, and thus no clear graphics are obtained.

Due to the above problems, although the sports towel according to the prior art is excellent in hygroscopic function, it is difficult to use for the various applications mentioned above due to the degradation of the quick drying and the difficulty of printing.

In order to solve such a problem, conventionally, in the towel fabric for photo prints in which a fabric is woven with three different types of yarns, each of which is formed of a warp that forms a center and a weft that forms a back and a surface, the warp that forms the center is pulled. PET-based cross-section yarns with 8-slit cross section twisted and twisted draw are used, and all of the weaving yarns forming the surface among the weft yarns are thread-processed through the twisting method, so that the dyeing and fastness of the disperse dyes It uses polyester microfiber of less than 1 denier with high single yarn fineness, and the weft forming the back side which mainly absorbs moisture among the weft yarns is made by using P / N composite yarn with buckle processing. Efforts have been made to solve the same problem.

For example, Korean Patent Publication No. 10-0559072 (Registration Date: 2006. 03. 03) discloses a fabric for photo printing and its manufacturing method with excellent fastness, and the same publication No. 10-0583462 (registered above) Date: 2006. 05. 18) discloses a towel fabric for photo printing with excellent fastness and a method of manufacturing the same as mentioned in the prior art, all of the prior art to form the back side of the main function of moisture absorption in the weft yarn P / N composite yarn is used for weaving yarn, so it has excellent drying function. However, 100% synthetic fiber requires a separate post-treatment process to improve static electricity generation and reduced flexibility. There is a problem that the touch to the skin and moisture absorption is poor.

On the other hand, the present invention further improves the prior art as a towel fabric having a structure of woven fabric with a weft forming the warp and the surface and the back and the center of the three different types of yarns, absorbing moisture in the weft yarn discharged Instead of P / N-based composite yarns, the weaving yarn that makes up the back side uses 100% natural cotton yarn that has been buckle-processed with three strands of yarn. The present invention was completed by developing a double paper towel fabric which is easy to maintain and hygroscopic and breathable.

Republic of Korea Patent Publication No. 10-0559072 (Registration Date: 2006. 03. 03) Republic of Korea Patent Publication No. 10-0583462 (Registration Date: 2006. 05. 18)

It is an object of the present invention to buckle the three strands of yarn in two stages instead of the P / N composite yarns of the wefts constituting the back surface of the wefts constituting the towel fabric printed by the digital inkjet photoprinter. By using 100% natural cotton yarn processed, it is to provide a manufacturing method of a towel fabric for digital photoprinting that is more flexible, tactile, breathable, and hygroscopic while maintaining the existing high resolution, wash fastness and drying function.

The manufacturing method of the towel fabric for digital photoprint of the present invention for solving the above problems is a double paper structure in which the fabric is woven with the warp and the back and weft forming the center using three different types of yarns In producing the towel fabric of the, the centered inclination is a polyester twist-shaped cross-section having a draw twist 8-slit cross section, the upper surface of the printed surface of the weft yarn The yarn is knitted into a long pile of 15 to 20mm, but 100% polyester microfiber of 0.3 denier or less of single yarn fineness with high dyeing and fastness to disperse dyes is used. The weft forming the back of the fabric is woven from 100% natural cotton yarn buckled with 3 strands of yarn in 2 stages. Silver is more than 15%, the length of the loop (loop) is 15 ~ 20mm, the number of loops is made in the range of 14 to 30 / inch, the surface of the woven fabric 4 to 8 brushed It is characterized by shearing (shearing) after.

The towel fabric for the digital photoprint manufactured by the manufacturing method of the present invention uses a polyester-based heteromorphic cross-section yarn as a centered warp yarn and a single yarn fineness of 0.3 denia or less as a weft forming a surface, and here, The weft forming the back side is a combination of three kinds of yarns, including 100% natural cotton yarn that has been buckled in three stages in two stages, and is woven into a double-cloth towel fabric, resulting in high resolution, wash fastness, and excellent drying performance. It is excellent in improving functions such as flexibility, touch, breathability, and hygroscopicity while maintaining it as it is.

In the manufacturing method of the towel fabric for digital photoprint of the present invention in the manufacture of a double paper towel fabric of woven fabric with a weft forming the center and the slope and the surface and the back side using three different kinds of yarn, The center of the inclined yarn is a polyester-based cross-section yarn, and the weft of the printed surface of the weft yarn is knitted into a long pile of 15 ~ 20mm, the single yarn fineness 0.3 denier high dyeing and fastness to the disperse dye 100% polyester microfiber of less than (denier) is used, and the weft forming the back side that absorbs and discharges moisture among the weft yarns is 100% natural by buckleing three strands of yarn in two stages. A cotton yarn is used to weave the fabric, and the surface of the woven fabric is prepared by shearing four to eight times and then shearing.

Hereinafter, a description will be given of a method for manufacturing a towel fabric for digital photoprint according to the present invention, which is intended to exemplify the invention to be easily implemented by those skilled in the art to which the present invention pertains. This does not mean that the technical spirit and scope of the present invention is limited.

The inclined portion forming the center of the fabric is composed of a polyester-type cross-sectional cross-section yarn made of a polyester DTY (Draw textured yarn) having an 8-slit cross section drawn in a draw twist, In addition to excellent movement, it maintains the cross section of the yarn during processing to improve the drying performance while improving the bulkiness. In DTY processing, the temperature is 170 ~ 195 ℃, the draw ratio is 1.65 ~ 1.75, D / Y Is 1.86 ~ 2.07, k-value was found to be in the range of 0.87 ~ 1.1 preferred.

As described above, the polyester-based sectional cross-section yarn having an 8-slit cross section having excellent moisture absorption and quick-drying function on the inclined portion has a capillary effect along 8 slits of water in the fabric transferred from the skin. It is known to improve the drying speed of water in the towel by using the principle that the moisture in the fabric is rapidly diffused into a large area and dried rapidly by the difference in moisture concentration with the surrounding fabric.

The weft of the printed surface of the weft is knitted in a long pile of 15 ~ 20mm, using a 100% polyester microfiber of less than 0.3 denier (denier) with high dyeing and fastness to the disperse dyes The weft yarn is twisted one yarn in the S direction (twist) and then set at a temperature of 100 ~ 120 ℃, the set yarn as a core yarn (core yarn) and the other strand Bulk yarn twisted through a process in which the core yarn is rotated in the opposite direction through the yarn in the Z direction and the bulk yarn is unwound and bulky while the yarn is an effect yarn. yarn).

The bulkiness of the twisted yarn (twisted yarn) used as the weft of the surface is controlled by varying the number of years in the S direction to be produced and later processed in effect (effect), but obtain a bulky twist yarn suitable for the surface of the fabric In order to maintain optimal sensitivity and color clarity, the 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%. Do.

That is, the most optimal transferability and color clarity are maintained when the twist yarn's bulkiness is 6 to 10% and S / Z firing ratio is 1.3 to 1.7. If the bulkiness of the yarn is lowered to 6% or less, the product's sensitivity is deteriorated, and the merchandise is inferior. In the bulkiness of 10% or more, the vividness of the color deteriorates due to the adhesion of the transfer paper and the relaxation of the tissue. When the firing ratio is less than 1.3, the bulkiness of the yarn becomes low, making color development as a towel paper difficult, and when the ratio exceeds 1.7, the bulkiness becomes high, resulting in poor adhesion of the transfer paper during photoprinting, making it difficult to obtain a vivid color print.

Next, the weft forming the back side of the fabric is processed in two stages using three strands of yarn, but two different strands of 100% natural cotton yarn having excellent hygroscopic performance are put in parallel to the buckle nozzle (buckle nozzel) at different input costs. The effect yarn on the higher side wraps the core yarn on the lower input side and forms a loop. Composed by compressing each other in a ratio to prevent loosening of the loop, but the bulkiness of the weft forming the back of the fabric is 15% or more, the length of the loop (loop) is 15 ~ 20mm and the loop ( The number of loops is in the range of 14 to 30 / inch was studied as the most preferable to implement the object of the present invention, such as hygroscopicity, flexibility, improved skin contact.

As a result, the present invention is to produce a towel fabric for digital photoprint using three different types of yarn, the inclination of the center of the fabric is a polyester-based release having an eight-slit cross section of draw twist The cross-section yarn is used after DTY processing, and the surface weft is 15 ~ 20mm long pile, and 100% polyester microfiber of 0.3 denier or less with single yarn fineness with high dyeing and fastness to disperse dyes To use, the weft of the back is to weave the fabric using 100% natural cotton yarn, and put the woven fabric into the brushing process, and then shearing the surface of the fabric four to eight times.

As described above, the present invention has been completed through numerous experiments. Hereinafter, the present invention will be described through preferred embodiments to be easily understood and implemented by those skilled in the art.
