Description

Manufacture method of textiles using Nylon / Polyester splittable composite fibers

The present invention relates to a method of manufacturing a textile fabric using a nylon / polyether split composite yarn, in particular a nylon / polyester split composite yarn further strengthens the split to improve the physical properties and feel of the fabric, and also control the fiber density It relates to a method for producing a textile fabric comprising a nylon / polyester split yarn that can produce a fabric having a desired fiber density.

Generally, the nylon / polyester split composite yarn refers to a new material that exhibits various sensitivity and functionality depending on the fabric design and dyeing processing conditions by dividing the micronized nylon and polyester by physical and chemical treatment. , High moisture permeability is expressed by the microcavities present between the fibers, high thermal barrier properties are expressed by the microcavities, and high cleaning properties are expressed by the characteristics of a large surface area per unit weight.

Due to the various properties as described above, a fiber fabric is recently made using a nylon / polyester split composite yarn. Textile fabrics containing such split nylon / polyester composite yarns are generally dyed through pretreatment processes such as hobbing and refining. In the hobbing and refining process, we remove various dirts such as grass or oils from raw sand during weaving. After the foreign matter is removed, it enters the dyeing process. Thereafter, the final product form of the textile fabric is produced through a drying or tenter process.

In the conventional method of manufacturing the textile fabric as described above, although the nylon / polyester split composite yarn is divided to some extent through the process of scouring and refining, the problem is that the physical properties and feel of the textile fabric are lowered due to the low degree of splitting. In addition, if the density of the fiber structure is formed in the weaving process, there is a problem that it is difficult to control the fiber density in a later process.

The present invention has been made to solve the above-mentioned problems of the prior art, by improving the physical properties / feel of the textile fabric by further division of nylon / polyester split composite yarn in the process after the pretreatment process such as hobbing / refining It is an object of the present invention to provide a method for producing a fiber fabric containing nylon / polyester split composite yarn having a high fiber density by allowing the fiber density to be adjusted in the process after the weaving process.

In order to solve the above problems, the present invention provides a method of manufacturing a fiber fabric including a nylon / polyester split composite yarn in which nylon and polyester are split in a ratio of 2: 8 to 5: 5. A weaving process of making dough using yarns and cotton yarns; A pretreatment process comprising a decanting / refining process for removing contaminants and foreign substances generated in the weaving process from the dough, and a bleaching process for decolorizing the dough after the decanting / refining process; A quench treatment step of immersing the raw material having undergone the pretreatment step in a sodium hydroxide solution and washing with water; After immersing the dough passed through the above-mentioned quenching process into a solution containing sodium hydroxide, an inhibitor and a softening agent in a bath, the temperature is gradually raised to a temperature of 1.2 to 3 ° C. in 1 minute to reach a temperature of 80 to 110 ° C. to 30 to 30 ° C. After aging for 60 minutes, the temperature was slowly lowered to a temperature of 1.5 to 3 ° C. in 1 minute, and washed with water by supplying water for 20 to 30 minutes at a temperature of 55 to 65 ° C. to divide the nylon / polyester split composite yarn. A division strengthening step of increasing; After immersed in the solution mixed with the shrinkage, bath softeners and inhibitors after the split-strengthening step, the temperature is gradually raised to a temperature of 1.2 ~ 3 ℃ in 1 minute to reach a temperature of 80 ~ 125 ℃ 30 ~ After aging for 60 minutes, the temperature is gradually lowered to 1.5 ~ 3 ℃ in 1 minute, and it is washed with water by supplying water for 20 ~ 30 minutes to reach the temperature of 55 ~ 65 ℃ and increasing density of dough. ; And a tenter step of smoothly processing the dough after the density-strengthening step is dried.

The manufacturing method of the fiber fabric containing the nylon / polyester split composite yarn according to the present invention constituted as described above is divided into a step of strengthening the dough containing a nylon / polyester split composite yarn having a low degree of splitting in the decanting and refining process By going through the nylon / polyester split composite yarn to be further divided, there is an advantage to improve the physical properties and feel of the fiber fabric due to this division.

In addition, by immersing the fiber fabric containing nylon / polyester split composite yarn in a solution containing a shrinkage agent and aged at a certain temperature, it is possible to control the density of the fiber fabric to obtain a fiber fabric having a desired density There is an advantage to that.

Hereinafter, with reference to the accompanying drawings an embodiment of a method for producing a fiber fabric containing nylon / polyester split composite yarn according to the present invention will be described in detail.

1 to 7 is a block diagram showing various embodiments of a method of manufacturing a textile fabric containing a nylon / polyester split composite yarn according to the present invention.

First, the present invention will be described with reference to FIG. 1. The method of manufacturing a textile fabric including the nylon / polyester split composite yarn according to the present invention includes a weaving step (S10), a pretreatment step (S20), and a sealant treatment. It comprises a process (S30), a division strengthening process (S40), a density strengthening process (S50), and a tenter process (S60).

The weaving process (S10) is a nylon / polyester split composite yarn consisting of nylon and polyester in a ratio of 2: 8 to 5: 5 as a warp or weft yarn and cotton yarn (棉 絲) split the nylon / polyester It is a process of making dough by using a weft or warp yarn to be woven like a composite yarn. Since the weaving process is a method widely introduced in the art, a description thereof will be omitted here.

In addition, the ratio of nylon and polyester is to realize the process implemented in the present specification using a composite yarn of the ratio of 2: 8 to 5: 5 currently produced. Nylon / polyester split composite yarns that deviate from the above ratios also limit the range of ratios as the effects of the process herein cannot be clearly demonstrated. The present specification does not manufacture a composite yarn according to the nylon / polyester ratio, but relates to a method of manufacturing a textile fabric using the composite yarn. Therefore, it will be apparent to those skilled in the art that limitations without explanation of the upper limit and the lower limit of the ratio of the composite yarn may be achieved to achieve the effect according to the process of the present specification.

The pretreatment step (S20) is made up of a call / refining process, and a bleaching process.

The descaling / refining process is a process of removing the contaminants and foreign substances generated by the use of various chemicals including the desizing agent in the weaving process (S10) from the dough.

The bleaching process is a process of decolorizing the dough in which foreign matter is removed through the decanting / refining process.

The sealant treatment step (S30) refers to a step of rinsing several times after immersing the dough passed through the pretreatment step (S20) in sodium hydroxide solution for 1-6 hours. The silk process is the first process developed in the United Kingdom, and the finished textile product is said to be similar to silk. This method uses the principle that cotton yarn swells in sodium hydroxide solution and eliminates kinking. The swelling of cotton yarn improves light reflection and softens the texture to give a silk-like feel. Not only does it get better, but the tensile strength is improved.

The split-strengthening step (S40) is gradually heated to a temperature of 1.2 ~ 3 ℃ in 1 minute after immersed in the solution mixed with water, sodium hydroxide, inhibitors and softeners in the bath after passing through the processing step (S30) ( Iv) and aged at 80 ~ 110 ℃ for 30 ~ 60 minutes, and then slowly lowered to 1.5 ~ 3.0 ℃ in 1 minute to reach the temperature of 55 ~ 65 ℃, water, sodium hydroxide, inhibitor And distilling the solution mixed with the softener in the bath, and then washing with water by supplying water for 20 to 30 minutes, then lowering the temperature to a temperature of 2.0 ° C. in 1 minute to take out the dough at a temperature of 40 ° C. It is a process to increase the splitting of the composite yarn. At this time, sodium hydroxide is used 10 ~ 30g per liter of water, the inhibitor is used 5g per liter of water, the softener in the bath is used 4g per liter of water.

The density-intensifying step (S50) is slowly immersed in a solution mixed with water, shrinking agent, bath softener and foam inhibitor after the split-strengthening step (S40) to a temperature of 1.2 ~ 3.0 ℃ in 1 minute ( Iv) and aged at 80 ~ 125 ℃ for 30 ~ 60 minutes, and then slowly lowered to 1.5 ~ 3.0 ℃ in 1 minute to reach the temperature of 55 ~ 65 ℃, water, shrinking agent, softener in bath. And then rinsing by discharging the mixed solution of the inhibitor, and then supplying water for 20 to 30 minutes, and then lowering the temperature to a temperature of 2.0 ° C. in 1 minute to take out the dough at a temperature of 40 ° C. to increase the density of the dough. It is a process.

The shrinkage agent used in the density strengthening process S50 may be recovered through a recovery device (not shown) after the process is completed. The shrinkage recovered through the recovery device can be recycled through filtering and concentration correction.

The tenter process (S60) smoothes the fibers after drying the dough through the density enhancing process (S50) and at the same time prevents impurities from adhering to the textile fabric using fluorine and an antistatic agent and prevents static electricity. It is a process to make it possible.

The dough is subjected to a repeated high temperature heat treatment process during the split hardening step (S40) and the density hardening step (S50). By repeating such a high temperature heat treatment process, the tear strength of the nylon / polyester split composite yarn fabric is lowered. Nylon / polyester split composite yarn fabrics having a lowered tear strength may have a change in physical properties. In order to prevent such a change in physical properties, the tenter process S60 is performed at the lowest temperature (120 to 150 degrees) so as not to lower the tear strength.

On the other hand, as shown in FIG. 2, the division strengthening step (S40) and the density enhancing step (S50) may be performed continuously as described above, but only the division step (S40) is performed and proceeds to the next step, or is divided. It is also possible to proceed to the next step after performing only the density step (S50) without performing the step (S40). This selection can be arbitrarily adjusted by considering the physical properties of the fabric to be manufactured by the operator.

  Here, as shown in FIG. 3, a reactive dye is applied to the dough that has undergone the division strengthening step (S40) or the density strengthening step (S50) between the split step (S40) or the density step (S50) and the tenter step (S60). Cotton side dyeing to dye a cotton yarn in a specific color (Cotton Side) dyeing process (S70) is further included. This is a process of aging the dough for 8 to 20 hours in the dyeing apparatus that stores the reactive dye so that the reactive dye is dyed to cotton yarn.

In addition, as shown in FIG. 4, a dispersion dye is applied to the dough that has undergone the division strengthening step (S40) or the density strengthening step (S50) between the split step (S40) or the density step (S50) and the tenter step (S60). , Nylon / polyester side dyeing process (S80) for dyeing the nylon / polyester split composite yarn in a specific color by adding an acid dye, bath softener and foam inhibitor. This is a process of dyeing nylon and polyester constituting the nylon / polyester split type yarn by aging for 30 to 60 minutes in a dyeing apparatus in which disperse dyes, acid dyes, bath softeners and inhibitors are stored. Disperse dyes react with polyester to dye polyester, and acid dyes react with nylon to dye nylon. Softeners in baths use 4g per liter of water, and inhibitors use 5g per liter of water.

On the other hand, cotton side dyeing process (S70) and nylon / polyester side dyeing process (S80) may be made continuously in one working process as shown in Figure 5, in this case after the cottonside dyeing process (S70) It is not limited to the nylon / polyester side dyeing step (S80), and the nylon side / side dyeing step (S70) may be made after the nylon / polyester side dyeing step (S80) is made first.

Here, as shown in Figure 6, weaving step (S10), pre-treatment step (S20), the squeeze step (S30), the division reinforcement step (S40) is sequentially performed after the dyeing and densification step (S90) tenter The process S60 may be performed.

As shown in FIG. 6, the density enhancing process (S50) and the nylon / polyester side dyeing process (S80) may be performed alone. In addition, as described above, the density enhancing process (S50) and the nylon / polyester side dyeing process (S80) may be continuously performed together in one bath.

The dyeing and density strengthening step (S90) is 1.0 ~ 1.2 per minute after immersing the dough through the split strengthening step (S40) in a mixed solution of water, disperse dyes, acid dyes, bath softeners, foam inhibitors and shrinkage agents The temperature was gradually raised to a temperature of 1 ° C., followed by primary aging for 10 minutes at a temperature of 80 ° C., followed by a temperature of 1.3 to 1.7 ° C. in 1 minute, followed by secondary aging at a temperature of 110 to 130 ° C., followed by 1.5 to 2.0 ° C. After the temperature was lowered to 55-65 ° C., a solution containing water, a disperse dye, an acid dye, a bath softener, an inhibitor, and a shrinkage agent was discharged, followed by washing with water for 20 to 30 minutes. It is a process of dyeing nylon / polyester split composite yarns to a specific color and increasing the density of dough by lowering the temperature at a temperature of 2.0 ° C. in one minute and drawing out the dough at a temperature of 40 ° C. At this time, the disperse dye reacts with the polyester to dye the polyester, and the acid dye reacts with the nylon to dye the nylon. Softeners in baths use 4g per liter of water, and inhibitors use 5g per liter of water.

On the other hand, between the dyeing and density enhancing process (S90) and the tenter process (S60), the cottonside dyeing process (S70) dyeing the cotton yarn to a specific color by dyeing the reactive dye on the dough after the dyeing and density enhancing process (S90) This is further included.

If the yarn is made of nylon / polyester split type composite yarn having a ratio of 2: 8 to 5: 5 in the warp and weft yarns, the process of the squeegee treatment among the various processes as described above (S30) The rest of the processes can be performed. One example is shown in FIG.

Briefly described with reference to Figure 7, one embodiment of the method of manufacturing a fiber fabric comprising a nylon / polyester split composite yarn according to the present invention is a nylon and polyester is composed of a ratio of 2: 8 to 5: 5 Weaving process (S10), pretreatment process (S20), split strengthening process (S40), dyeing and density strengthening process (S90), and tenter process for making dough with nylon / polyester split composite yarn as warp and weft It consists of S60. Since the processes illustrated in FIG. 7 have already been described above, a description thereof will be omitted here.
