1 is a process flow chart according to an embodiment of the present invention.

Unless defined otherwise, all technical terms used in the present invention have the following definitions and are consistent with the meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

The term 'healthcare' fiber or fabric is a fibrous product with functionalities such as cleanliness, comfort, protection, hygiene, antimicrobial activity, and thermal insulation, to maintain, promote or restore the health of the human body and to further enhance comfort in daily life. Includes fibers used directly in and textile products used in the vicinity of human life.

The term 'double covering yarn' refers to yarns covered by twisting two drowns in different directions in one screening.

Throughout this specification, the terms “comprises” and “comprising”, unless otherwise indicated in the context, include a given step or component, or group of steps or components, but any other step or component, or It is to be understood that it does not exclude a step or group of components.

Hereinafter, the present invention will be described in detail.

Silk has good breathability, hygroscopicity and moisture resistance, and is comfortable to wear. It has excellent excellence in thermoregulation and comfort. The present invention provides an antimicrobial-health functional silk fabric excellent in antimicrobial properties, heat retention, deodorizing power and the like through the physical processing of the surface such as fiber complexion, tissue diversification, hair growth technology while maintaining these properties of silk.

Referring to Figure 1, the manufacturing method of the silk fabric according to an embodiment of the present invention includes a silk fabric weaving step (S1), drying step (S2), and brushing step (S3), and optionally a post-processing step (S4) is included.

First, the silk fabric weaving step (S1) is a process of weaving the fabric by weaving the weft yarns and warp yarns, using a double covering yarn as the weft yarn and silk silk yarn as the warp yarn. Thus, step (S1) includes a step (S1-1) of manufacturing a double covering yarn which is a weft yarn and a step (S1-2) of weaving a fabric with a weft yarn and a silk warp yarn.

In the step (S1-1), the double covering yarn is preferably manufactured by twisting using antimicrobial material yarn (70d) and silk (21 single yarn) and silk (21 single yarn) as the screening. The antimicrobial material yarns are not particularly limited as long as they are compatible with silk and have antimicrobial properties, but antimicrobial yarns containing silver (Ag) nanoparticles in a synthetic fiber yarn may be preferably used. In a specific example, commercially available MAGICSILVER NANO (Hyosung Co., Ltd.) contains silver nanoparticles in nylon yarns, which inhibits the growth of various bacteria such as Staphylococcus aureus, pneumococcus, Escherichia coli, MRSA bacteria, and the like. Its function is not deteriorated, and thus it has semi-permanent antibacterial properties. In addition, it emits far-infrared rays, which are beneficial to the human body, promotes blood circulation, maintains health, and there is no allergic reaction and no harmful substances to the human body. In addition, various silver nano antimicrobial agents may be used. The silver nanoparticles may be a nanocomposite material in which nanosilver particles, preferably pure metals of 1 to 3 nm level, are bonded to silica particles of 10 nm or less. These new nanomaterials exhibit nanoparticle characteristics such as high specific surface area and photospecific phase transition phenomena, and are a multifunctional new material that has a combination of silica sterilization, antibacterial, and conductive functions with adsorption, deodorization, and far-infrared radiation.

In the present invention, the antimicrobial yarn is used as a screening to prepare the weft yarn, thereby providing antimicrobial properties and health functionalities to the silk fabric.

In the step S1-2, the weaving of the silk fabric is preferably woven into a multi-layer structure using a dobby weaving machine with a double beam. When weaving with a double beam like this, the effect of the multi weaving can be obtained even in a normal repia loom. However, it is desirable to minimize the difference in tension because it is difficult to show a uniform surface due to the difference in tension. It is preferable to set the cetin tissue so that the formation of the cows during the hair processing can be performed while reducing the fabric cross point which is the main cause of skin damage.

Accordingly, the present inventors have designed a double beam using various heterogeneous materials. Weaving conditions were investigated to form a jacquard with poly-based tissues capable of embossing effects using a double beam design of SILK + SILK, Silk + Poly, and Silk + Cotton. There was no problem on the weaving of the woven fabric to make the jacquard poly, but it was difficult to form the silk brush in the surface processing and the tearing of the fabric occurred badly. Therefore, in the present invention, when weaving was performed after weaving by using the warp yarn as the silk and the weft yarn as the functional material yarn, it was confirmed that the proper shrinkage and raising of the surface were made very well.

That is, in the present invention, the warp is woven the fabric using silk yarn. At this time, when the other side of the woven fabric is subjected to the napped process, shrinkage occurs, so it is necessary to adjust the density of the slope in consideration of this. In addition, we use elastic functional material yarns for weft yarns. We used double covering yarns covering silk for magic silver screening, and density control is necessary in this case.

Next, the drying step (S2) includes a dehydration and drying step (S2-2) after refining and dyeing (S2-1).

In the step (S2-1), since the surface of the fabric should be smoothly treated due to the characteristics of the fabric, the soap-alkali refining method is used so that the annual reduction rate is about 25%. Dyeing is done by increasing the color fastness due to the nature of the material to be frequently washed.

After the refining and dyeing process in the step (S2-2) to absorb the moisture in the silk fabric using an inhaler and to minimize the tension at a temperature of 80 ℃ or less to dry the fabric.

Next, by performing brushing on the silk fabric dried in the brushing step (S3) it is excellent in moisture absorption water repellency and exhibits heat retention. When brushed by the general silk processing method, there is almost no shrinkage, so a lot of weft of the weft occurs, which causes a defect. Therefore, it is important to develop a processing process that reduces stress and minimizes loss of silk protein. In addition, it is important to minimize the fabric crossing point, which is the main cause of skin damage when it comes in direct contact with the skin, and it is important to search for conditions and tissues effective for hair processing.

Brushing process (S3-1) is a step of forming a loop brushed on the surface of the dried silk fabric using a brush, usually required more than three times, and shearing (shearing) to control the height of the raised wool ( It is preferable to use S3-2) together. The shearing operation is a job of cutting the hairs formed through brushing to a certain height.

As a result of the study of the present inventors, the brushing condition of the silk fabric improved the strength of the yarn using the covering yarn, but was still weaker than the general polyester, so the brushing process (S3-1) used the loop raising method rather than the cut brushing. It is preferable to work with raising conditions 8 times using two interlocking brush. The brush has 24 to 32 needle rollers disposed on the cylinder, and the roller has a counter pile roller in a direction opposite to a needle roller with a needle in the direction in which the cylinder rotates; CPR) are alternately arranged one by one, and this is done by pulling the fabric surface while pulling the fabric as the roller rotates against the fabric.

1-2 times for brushing (S3-1), drum speed 190, counter pile drum speed is 5 ~ 10% of the drum speed, pile drum speed is -10 ~ -15% of the drum speed, fabric processing speed 20m It is preferable to proceed with the counter raising in a condition of / min, and raising the pile raising to form the loop as long as possible.

The brushing process 3-4 times is drum speed 200, counter pile drum speed is 15-20% stronger than drum speed, pile drum speed is -0.5% weaker than drum speed, fabric cutting speed 20m / min, counter pile It is preferable to harden and to weaken the pile to cut the pile of the formed fabric to form hair on the surface.

The brushing 5-6 times is preferably carried out while increasing the counter pile speed (2% up).

The brushing process is performed 7 to 8 times to increase the rpm of the drum and the counter pile to treat the hair (drum speed 210).

According to the raising process of the present invention, it is possible to prevent damage to the screening and to maintain elasticity after processing.

Optionally, a post-processing step S4 may be performed on the brushed silk fabric. Post-processing step (S4) may include functional processing (S4-1) and / or final finishing process (S4-2).

Functional processing (S4-1) may be a processing to process the silver nanoparticles to supplement the antimicrobial properties. The antimicrobial test showed a 99.9% effect after brushing, but a slight difference of 95.5% for fabrics treated before brushing.

Final finishing (S4-2) may be performed, for example, using a diamond brush coated with diamond powder to perform brush processing to provide fine dust cut to the fabric during brushing and shearing processes. Such a smoothly treated part can act on the sympathetic nerve when it comes into contact with the skin to make it feel comfortable, increase immunity, activate metabolism and promote fatigue recovery.

As described above, the present invention provides a superior antimicrobial, warmth and comfort to the fabric by using a double covering technique using a semi-permanent antimicrobial material yarn as a weft yarn, weaving silk yarn using a warp yarn. Therefore, after the production and weaving of medical textile paper for bed sheets used in hospitals and for patient use, the surface of the silk is machined only physically using a brush to raise the silk surface with high heat retention. It prevents skin allergies that are prone to use or chemical processing, and silk amino acid is supplied to the skin to provide health functional textile paper for improving skin diseases. Such functional textile papers of the present invention can be effectively used in medical fibers, underwear, bed mats, underwear, or bedding.

Hereinafter, the present invention will be described in detail with reference to examples. However, these examples are intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.

Example 1

Weaving was performed by a double beam design under the conditions shown in Table 1 below.

Experimental Example 1 Shrinkage

Since the yarn was used in the oblique direction, the shrinkage was about 5%, while the shrinkage was very small in the weft direction. While the warp direction was almost the same as that of the conventional silk fabrics, the weft yarn was a filament fiber until weaving from the raised tissue, but the shrinkage did not appear as a result of the surface modification in the form of staple fiber through brushing. Also spec 1. and spec. The difference in shrinkage over the slope of 2 is assumed to come from tissue and density. Table 2 below shows the shrinkage ratios of the light and weft yarns of the samples.

[Example 2]

The screening is magic silver (70d) and the drowning is silk (21 single yarn) and silk (21 single yarn), and the antimicrobial double covering yarn twisted at 800 ~ 1,200 t / m is used as the weft, Weaving was conducted with the silk silk yarn as a slope. After woven and dyed for 30 to 40 minutes at 90 ℃ or less woven silk fabric was absorbed moisture in the silk fabric and dried to minimize the tension at a temperature of 80 ℃ or less. Refinement was refined at 15% of soap, 10% of sodium carbonate (o.w.f) at 95 ° C for 1 hour, and the dyeing was dyed with reactive dyes to improve washing fastness, and no width adjustment was made to control shrinkage after brushing.

Loop brushing was formed on the surface of the dried silk fabric using a brush. The brushing process was used two interlocking brush, and was performed eight times under the conditions shown in Table 3.

Raising processing condition 1 time: drum speed 190, counter pile drum speed is 5 ~ 10% of drum speed, pile speed -10 ~ -15% of drum speed, fabric raising speed 20m / min. Strengthen the loop to form as long as possible and give the fabric an appropriate axis to reduce the change in strength and shape of the fabric even after the cut
2 times: Proceed as same as 1 time
3 times: drum speed 200, counter pile drum speed is 15-20% stronger than drum speed, pile drum speed is -0.5% weaker than drum speed, counter pile is strong at 20m / min fabric cutting speed Cuts pile of weakly formed fabric to form hair on the surface
4 times: Same condition as 3 times
Episode 5: increase the counter pile speed (2% up)
6 times: Repeat 5 times
Episode 7: hair growth by increasing the rpm of drum and counter pile (drum speed 210)
8 times: same condition as 7 times

Experimental Example 2 Washing Fastness

In general, existing silks have been subjected to many acid dyes, but have low fastness and are not suitable for dyeing materials that require washing. Therefore, it was dyed through reactive dyeing, and the degree of fastness was confirmed to be excellent as shown in Table 4 below.

Experimental Example 3 Friction Fastness

As the material directly touches the skin, the fastness of friction is an important factor. If the surface is too rough, it is inadequate and if the surface agglomeration or bursting occurs during friction, it is important to maintain an appropriate surface because the effect is reduced to a functional product.

So far I looked at the center of the preferred embodiment for the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
