Description

천연직물 바닥재{NATURAL FABRIC FLOORING}Natural fabric flooring {NATURAL FABRIC FLOORING}

본 발명은 천연직물 바닥재에 관한 것이다.The present invention relates to a natural fabric flooring.

바닥재는 호텔이나 사무실, 매장, 자동차 등의 실내 바닥재로 사용된다. Flooring is used as indoor flooring in hotels, offices, stores, and automobiles.

바닥재는 백색 폴리염화비닐(PVC) 시트층에 무패턴의 인쇄 또는 전사인쇄를 실시한 후, 투명 PVC로 인쇄층을 보호하고, 표면 엠보를 부여하여 제조된다. The flooring material is produced by performing a patternless printing or transfer printing on a white polyvinyl chloride (PVC) sheet layer, protecting the printing layer with transparent PVC, and imparting a surface emboss.

그러나, 이러한 구조를 갖는 바닥재는 습도와 온도 변화에 따른 치수 안정성이 불안정하고, 외관이 좋지 못한 단점이 있다.However, the flooring having such a structure has unstable dimensional stability due to changes in humidity and temperature, and has a poor appearance.

이러한 문제점을 해결하고자, 유리섬유 시트와 같은 변형 방지층을 포함하여 바닥재를 제조하는 연구가 진행되고 있다. 하지만, 유리섬유 시트는 유연성이 좋지 못한 단점이 있다. 또한, PVC 층과 변형 방지층이 적층된 구조에서 층과 층 사이가 벌어지는 현상이 발생한다. In order to solve this problem, research into manufacturing a flooring material including a strain preventing layer such as a glass fiber sheet has been conducted. However, the glass fiber sheet has a disadvantage of poor flexibility. In addition, in the structure in which the PVC layer and the strain prevention layer are stacked, a phenomenon occurs between the layers.

따라서, 유연성과 치수 안정성이 우수하고, 고급스러운 외관을 나타낼 수 있는 바닥재의 연구가 필요하다.Therefore, it is necessary to study a flooring material having excellent flexibility and dimensional stability and exhibiting a luxurious appearance.

본 발명에 관련된 배경기술로는 대한민국 공개특허공보 제10-2016-0029953호(2016.03.16. 공개)가 있으며, 상기 문헌에는 친환경 바닥재가 기재되어 있다.Background art related to the present invention includes the Republic of Korea Patent Publication No. 10-2016-0029953 (2016.03.16. Published), the document describes an environmentally friendly flooring.

본 발명의 목적은 정전기 발생을 최소화하고, 치수안정성을 향상시키기 위해, 치수 안정층, 제1 PVC 백킹층, 제2 PVC 백킹층, 천연직물층, 대전 방지층을 포함하는 천연직물 바닥재를 제공하는 것이다.An object of the present invention is to provide a natural fabric flooring material including a dimensional stability layer, a first PVC backing layer, a second PVC backing layer, a natural fabric layer, and an antistatic layer to minimize static electricity generation and improve dimensional stability. .

상기 하나의 목적을 달성하기 위한 본 발명에 따른 천연직물 바닥재는 분산되어 있는 유리섬유에 고분자 수지가 함침되어 있는 치수 안정층; 상기 치수 안정층 상부에 위치하는 제1 PVC 백킹층; 상기 치수 안정층 하부에 위치하는 제2 PVC 백킹층; 상기 제1 PVC 백킹층 상부에 위치하는 천연직물층; 및 상기 천연직물층 상부에 위치하는 대전 방지층;을 포함하고, 상기 치수 안정층의 양 면에 PVC 백킹층이 위치하는 것을 특징으로 한다.The natural fabric flooring according to the present invention for achieving the above object is a dimensional stability layer impregnated with polymer resin in dispersed glass fibers; A first PVC backing layer positioned over the dimensionally stable layer; A second PVC backing layer positioned below the dimensionally stable layer; A natural fabric layer located on the first PVC backing layer; And an antistatic layer positioned over the natural fabric layer, wherein PVC backing layers are located on both sides of the dimensional stability layer.

상기 유리섬유는 중공섬유일 수 있다.The glass fiber may be a hollow fiber.

상기 제1 PVC 백킹층은 PVC 매트릭스 내에 기공을 포함하는 발포물일 수 있다.The first PVC backing layer may be a foam including pores in a PVC matrix.

상기 제2 PVC 백킹층은 PVC 100중량부에 대하여, NBR 10~40중량부를 포함하는 비발포물일 수 있다.The second PVC backing layer may be a non-foaming material containing 10 to 40 parts by weight of NBR with respect to 100 parts by weight of PVC.

상기 천연직물층은 삼베, 모시, 또는 마를 포함할 수 있다.The natural fabric layer may include burlap, linen, or hemp.

상기 대전 방지층은 폴리테트라플루오로에틸렌(Polytetrafluoroethylene, PTFE)을 포함할 수 있다.The antistatic layer may include polytetrafluoroethylene (PTFE).

본 발명에 따른 천연직물 바닥재는 카펫타일용 백킹층인 제2 PVC 백킹층을 포함함으로써, 천연직물 바닥재의 유연성을 높여 층과 층 사이의 벌어짐을 최소화하는 효과가 있다. The natural fabric flooring according to the present invention includes the second PVC backing layer which is a backing layer for carpet tiles, thereby increasing the flexibility of the natural fabric flooring and minimizing the gap between the layers.

또한, 제1 PVC 백킹층과 제2 PVC 백킹층 사이에 존재하는 치수 안정층에 의해, 온도와 습도에 의한 수축과 팽창을 최소화하는 효과가 있다.In addition, by the dimensionally stable layer existing between the first PVC backing layer and the second PVC backing layer, there is an effect of minimizing shrinkage and expansion due to temperature and humidity.

아울러, 천연직물 바닥재의 정전기 발생을 최소화함으로써, 기존 대전방지 타일의 대체 제품으로 적용 가능하다.In addition, by minimizing the generation of static electricity in the natural fabric flooring, it can be applied as an alternative to existing antistatic tiles.

도 1은 본 발명에 따른 천연직물 바닥재의 단면도이다.1 is a cross-sectional view of a natural fabric flooring according to the present invention.

본 발명의 이점 및 특징, 그리고 그것들을 달성하는 방법은 첨부되는 도면과 함께 상세하게 후술되어 있는 실시예들을 참조하면 명확해질 것이다. 그러나 본 발명은 이하에서 개시되는 실시예들에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예들은 본 발명의 개시가 완전하도록 하며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이며, 본 발명은 청구항의 범주에 의해 정의될 뿐이다. 명세서 전체에 걸쳐 동일 참조 부호는 동일 구성요소를 지칭한다.Advantages and features of the present invention, and methods for achieving them will be clarified with reference to embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only the embodiments allow the disclosure of the present invention to be complete, and the ordinary knowledge in the technical field to which the present invention pertains. It is provided to fully inform the holder of the scope of the invention, and the invention is only defined by the scope of the claims. The same reference numerals refer to the same components throughout the specification.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 천연직물 바닥재에 관하여 상세히 설명하면 다음과 같다.Hereinafter, a natural fabric flooring according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 천연직물 바닥재의 단면도이다.1 is a cross-sectional view of a natural fabric flooring according to the present invention.

도 1을 참조하면, 본 발명에 따른 천연직물 바닥재는 치수 안정층(10), 제1 PVC 백킹층(20), 제2 PVC 백킹층(30), 천연직물층(40) 및 대전 방지층(50)을 포함한다. 본 발명에 따른 천연직물 바닥재는 기존의 PVC 타일에 비해 시공성이 우수하고, 카펫타일의 대체 제품으로 적용 가능하다. Referring to FIG. 1, the natural fabric flooring according to the present invention includes a dimensionally stable layer 10, a first PVC backing layer 20, a second PVC backing layer 30, a natural fabric layer 40, and an antistatic layer 50. ). The natural fabric flooring according to the present invention has superior construction performance compared to conventional PVC tiles, and can be applied as an alternative product for carpet tiles.

또한, 카펫타일용 제2 PVC 백킹층을 적용함으로써, 천연직물 바닥재의 유연성이 우수하여 층과 층 사이의 틈 벌어짐 현상을 최소화하는 효과가 있다.In addition, by applying a second PVC backing layer for carpet tiles, the flexibility of the natural fabric flooring is excellent, thereby minimizing the gap between the layers.

상기 치수 안정층(10)은 온도와 습도에 의한 치수의 변형을 최소화하는 역할을 한다. 상기 치수 안정층(10)은 분산되어 있는 유리섬유에 고분자 수지가 함침되어 있는 구조를 가진다. 상기 치수 안정층(10)은 고분자 수지가 함침된 유리섬유를 포함하여, 매트릭스 형상을 나타낸다. 상기 치수 안정층(10)에 포함되는 유리섬유는 중공섬유일 수 있다. 상기 치수 안정층(10)에 중공섬유를 사용하는 경우, 중공섬유의 비표면적이 넓기 때문에, 고분자 수지가 유리섬유에 함침되는 면적이 넓어진다. The dimensional stability layer 10 serves to minimize deformation of the dimension due to temperature and humidity. The dimensional stability layer 10 has a structure in which a polymer resin is impregnated into dispersed glass fibers. The dimensional stability layer 10 includes a glass fiber impregnated with a polymer resin, and exhibits a matrix shape. The glass fibers included in the dimensional stability layer 10 may be hollow fibers. When hollow fibers are used for the dimensionally stable layer 10, since the specific surface area of the hollow fibers is large, the area where the polymer resin is impregnated into the glass fibers is widened.

따라서, 치수 안정층(10)의 0.1~1.0mm의 일정한 두께 범위에서 치수의 변형을 최소화하는 효과가 있다. 상기 치수 안정층(10)의 두께가 0.1mm 미만인 경우, 치수안정의 효과가 불충분할 수 있다. 상기 치수 안정층(10)의 두께가 1.0mm를 초과하는 경우, 치수안정의 효과 없이 두께만 두꺼워지면서 바닥재의 제조비용만 증가하게 된다.Therefore, there is an effect of minimizing deformation of the dimension in a constant thickness range of 0.1 to 1.0 mm of the dimension stabilizing layer 10. When the thickness of the dimensional stability layer 10 is less than 0.1 mm, the effect of dimensional stability may be insufficient. When the thickness of the dimensional stability layer 10 exceeds 1.0 mm, only the thickness of the floor material is increased without increasing the effect of dimensional stability, and only the manufacturing cost of the flooring material is increased.

상기 고분자 수지는 아크릴계 수지, 멜라민계 수지 및 우레탄계 수지 중 1종 이상을 포함한다. 상기 고분자 수지는 부틸아크릴레이트, 에틸헥실아크릴레이트 등을 포함하는 아크릴계 수지를 사용하는 것이 바람직하다.The polymer resin includes at least one of acrylic resin, melamine resin and urethane resin. As the polymer resin, it is preferable to use an acrylic resin containing butyl acrylate, ethylhexyl acrylate, and the like.

상기 고분자 수지는 트리이소부틸알루미늄 클로라이드(tri isobutyl aluminium chloride)를 포함하여, 치수 안정층(10)에 유연성을 부여할 수 있다. 이에 따라, 천연직물 바닥재에서 층과 층 사이의 틈 벌어짐 현상을 최소화할 수 있다.The polymer resin may include triisobutyl aluminum chloride, to impart flexibility to the dimensional stability layer 10. Accordingly, the gap between the layers in the natural fabric flooring can be minimized.

상기 제1 PVC 백킹층(20)은 상기 치수 안정층(10)의 상부에 위치한다. 상기 제1 PVC 백킹층(20)은 PVC 재질의 매트릭스 내에 기공을 포함하는 발포물이다. 상기 제1 PVC 백킹층(20)은 기공률이 10~50vol%일 수 있으나, 이에 제한되는 것은 아니다. 상기 제1 PVC 백킹층(20)은 발포에 의해 쿠션감이 우수하며, 천연직물 바닥재의 상부로부터 가해지는 외부 충격을 흡수한다. The first PVC backing layer 20 is positioned above the dimensionally stable layer 10. The first PVC backing layer 20 is a foam containing pores in a matrix of PVC material. The first PVC backing layer 20 may have a porosity of 10-50 vol%, but is not limited thereto. The first PVC backing layer 20 is excellent in cushioning by foaming, and absorbs external impact applied from the top of the natural fabric flooring.

상기 제2 PVC 백킹층(30)은 상기 치수 안정층(10)의 하부에 위치한다. 상기 제2 PVC 백킹층(30)은 PVC 재질의 매트릭스를 포함하는 비발포물이다. 구체적으로는, 상기 제2 PVC 백킹층(30)은 PVC 100중량부에 대하여, NBR(nitrile-butadiene rubber) 10~40중량부를 포함한다. 상기 NBR은 쿠션감과 충격 흡수가 뛰어난 재질로, 내구성이 우수한 고무이다. 상기 NBR의 함량이 10~40중량부를 벗어나는 경우, 바닥면으로부터 천연직물 바닥재의 밀림 현상을 최소화하기에 불충분하다. The second PVC backing layer 30 is located below the dimensionally stable layer 10. The second PVC backing layer 30 is a non-foaming material comprising a matrix of PVC material. Specifically, the second PVC backing layer 30 includes 10 to 40 parts by weight of NBR (nitrile-butadiene rubber) with respect to 100 parts by weight of PVC. The NBR is a material having excellent cushioning and shock absorption, and is an excellent rubber. When the content of the NBR exceeds 10 to 40 parts by weight, it is insufficient to minimize the phenomenon of pushing the natural fabric flooring from the bottom surface.

상기 제2 PVC 백킹층(30)에 NBR이 포함됨으로써, 바닥면으로부터 천연직물 바닥재의 밀림 현상을 최소화할 수 있다. By including NBR in the second PVC backing layer 30, it is possible to minimize the phenomenon of pushing the natural fabric flooring from the bottom surface.

이처럼, 본 발명에 따른 천연직물 바닥재는 상기 치수 안정층(10)의 양 면에 PVC 백킹층(20, 30)이 위치한다. 상기 천연직물 바닥재는 온도 상승 시 팽창하는 제1 PVC 백킹층(20)과 온도 하강 시 수축하는 제2 PVC 백킹층(30)이 적층된 구조를 갖는다. As described above, in the natural fabric flooring according to the present invention, PVC backing layers 20 and 30 are located on both sides of the dimensional stability layer 10. The natural fabric flooring has a structure in which a first PVC backing layer 20 that expands when the temperature rises and a second PVC backing layer 30 that contracts when the temperature decreases are stacked.

상기 제1 PVC 백킹층(20)과 상기 제2 PVC 백킹층(30)이 열팽창과 열수축 작용을 상호 보완하여, 온도변화에 따른 천연직물 바닥재의 치수가 영구 변형되는 현상을 방지할 수 있다.The first PVC backing layer 20 and the second PVC backing layer 30 complement each other for thermal expansion and thermal contraction, thereby preventing the permanent deformation of the natural fabric flooring due to temperature changes.

상기 천연직물층(40)은 상기 제1 PVC 백킹층(20)의 상부에 위치한다. 상기 천연직물층(40)은 삼베, 모시 또는 마를 포함한다. 상기 천연직물층(40)은 천연직물 자체의 촉감 및 제직 형태에 따라, 삼베, 모시 또는 마와 같은 무늬를 천연직물 바닥재에 그대로 나타나게 한다. The natural fabric layer 40 is positioned on the first PVC backing layer 20. The natural fabric layer 40 includes burlap, linen, or hemp. The natural fabric layer 40 makes a pattern such as burlap, ramie or hemp appear on the natural fabric flooring as it is depending on the texture and weaving form of the natural fabric itself.

따라서, 자연적이고 고급스러운 미감과 같은 장식 효과를 나타낸다. 뿐만 아니라, 상기 삼베, 모시 또는 마와 같은 천연직물을 소정의 염료로 염색하여 다양한 색상으로 제작 가능하다.Therefore, it exhibits a decorative effect such as a natural and luxurious aesthetic. In addition, the natural fabrics such as hemp, ramie or hemp can be dyed with a predetermined dye to produce various colors.

예를 들어, 상기 천연직물층(40)은 황마로 형성될 수 있다. 상기 황마는 직경이 0.01~0.1mm인 섬유 가닥 3가닥을 결합하여 하나의 실로 만든 다음, 이러한 실을 가닥으로 결합한 후 직물 형태로 구성한 것이다. For example, the natural fabric layer 40 may be formed of jute. The jute is made of a single thread by combining three strands of fiber strands having a diameter of 0.01 to 0.1 mm, and then combining these threads with strands to form a fabric.

상기 대전 방지층(50)은 상기 천연직물층(40)의 상부에 위치한다. 상기 대전 방지층(50)은 천연직물 바닥재의 표면에 먼지와 같은 이물질이 쉽게 달라붙는 것을 방지하는 역할을 한다. 또한, 상기 대전 방지층(50)은 외부로부터 발생하는 정전기를 효과적으로 제어하는 역할을 한다.The antistatic layer 50 is positioned on the natural fabric layer 40. The antistatic layer 50 serves to prevent foreign matter such as dust from easily attaching to the surface of the natural fabric flooring. In addition, the antistatic layer 50 serves to effectively control static electricity generated from the outside.

상기 대전 방지층(50)은 투명 재질의 폴리테트라플루오로에틸렌(PTFE)을 포함한다. 상기 대전 방지층(50)은 전도성 고분자 조성물을 도포한 후, 경화시켜 형성된다. 예를 들어, 상기 전도성 고분자 조성물은 PTFE와 유기용매를 혼합한 것이다. 상기 대전 방지층(50)의 표면 저항값은 1.0Х104Ω/cm2 이상 내지 5.0Х109Ω/cm2 이하를 나타낸다. 또한, 상기 대전 방지층(50)의 표면 마찰값은 50V 이상 내지 100V 이하를 나타낸다.The antistatic layer 50 includes transparent material of polytetrafluoroethylene (PTFE). The antistatic layer 50 is formed by applying a conductive polymer composition and then curing. For example, the conductive polymer composition is a mixture of PTFE and an organic solvent. The surface resistance value of the antistatic layer 50 represents 1.0Х10 4 Ω / cm 2 or more to 5.0Х10 9 Ω / cm 2 or less. In addition, the surface friction value of the antistatic layer 50 is 50 V or more and 100 V or less.

상기 대전 방지층(50)은 테트라에틸포스포늄 벤즈이미다졸 (tetraethylphosphonium benzimidazolide)를 더 포함한다. 상기 대전 방지층(50)에 테트라에틸포스포늄 벤즈이미다졸을 포함하여 대전 방지 효과를 극대화할 수 있다. 여기서, 테트라에틸포스포늄 벤즈이미다졸은 PTFE 100중량부에 대하여, 20~30중량부로 포함된다. 이 범위를 벗어나는 경우, 대전 방지 효과 없이 제조 비용만 상승하게 된다.The antistatic layer 50 further includes tetraethylphosphonium benzimidazolide. The antistatic effect may be maximized by including tetraethylphosphonium benzimidazole in the antistatic layer 50. Here, tetraethylphosphonium benzimidazole is contained in 20 to 30 parts by weight with respect to 100 parts by weight of PTFE. If it is outside this range, only the manufacturing cost increases without the antistatic effect.

상기 대전 방지층(50)은 대전 방지제로서 카본 블랙을 더 포함한다. 상기 카본 블랙은 1~100nm의 직경을 가질 수 있다. 상기 대전 방지층(50)은 나노 크기의 카본 블랙을 더 포함하여, 대전 방지 효과를 극대화할 수 있다.The antistatic layer 50 further includes carbon black as an antistatic agent. The carbon black may have a diameter of 1 to 100 nm. The antistatic layer 50 may further include a nano-sized carbon black, thereby maximizing the antistatic effect.

이처럼, 상기 대전 방지층(50)에 PTFE를 포함함으로써, 기존의 대전방지 타일과 동등 이상의 물성을 나타낼 수 있다. 또한, 상기 대전 방지층(50)에 테트라에틸포스포늄 벤즈이미다졸과, 카본 블랙를 더 첨가함으로써, 천연직물 바닥재의 대전 방지 효과를 극대화하는 효과가 있다. As described above, by including PTFE in the antistatic layer 50, physical properties equal to or greater than that of the existing antistatic tile can be exhibited. In addition, by adding tetraethylphosphonium benzimidazole and carbon black to the antistatic layer 50, there is an effect of maximizing the antistatic effect of the natural fabric flooring.

따라서, 상기 대전 방지층(50)을 포함하는 천연직물 바닥재는 사무실 등의 정전기 발생을 최소화해야 하는 장소에 적용 가능하다. Therefore, the natural fabric flooring material including the antistatic layer 50 can be applied to a place where static electricity generation, such as an office, should be minimized.

본 발명에 따른 천연직물 바닥재는 층과 층 사이에 PVC 접착제 또는 천연접착제를 도포하여, 층과 층 사이를 접착할 수 있으나, 이에 제한되는 것은 아니다.The natural fabric flooring according to the present invention can be applied between a layer and a layer by applying a PVC adhesive or a natural adhesive, but is not limited thereto.

이와 같이 천연직물 바닥재에 대하여 그 구체적인 실시예를 살펴보면 다음과 같다.Looking at the specific embodiment of the natural fabric flooring as described above is as follows.

비교예 1Comparative Example 1

실시예 1과 동일한 조건으로 천연직물 바닥재를 제조하되, 제1 PVC 백킹층을 포함하지 않는 구성으로 천연직물 바닥재를 제조하였다.A natural fabric flooring material was prepared under the same conditions as in Example 1, and a natural fabric flooring material was manufactured in a configuration not including a first PVC backing layer.

2. 물성 평가 방법 및 그 결과2. Method for evaluating physical properties and results

1) 치수 안정성 평가1) Dimensional stability evaluation

제조된 천연직물 바닥재에 대하여, 치수 안정성을 평가하였다.For the manufactured natural fabric flooring, dimensional stability was evaluated.

60±2℃의 순환 오븐에서 2시간 동안 천연직물 바닥재를 체류시킨 후, 천연직물 바닥재의 가로축과 세로축의 치수 변화율(수축 또는 팽창)을 측정하였다. 치수 변화율이 ±0.5% 이하일 때, 치수 안정성 평가에서 합격한 것으로 본다.After retaining the natural fabric flooring in a circulating oven at 60 ± 2 ° C. for 2 hours, the dimensional change rate (contraction or expansion) of the horizontal and vertical axes of the natural fabric flooring was measured. When the rate of dimensional change is ± 0.5% or less, it is considered that the dimensional stability evaluation has passed.

2) 표면 저항 측정2) Surface resistance measurement

적용전압 500V, 60초, 20±2℃, 65±2% RH, 시험장비; TOA SME-8311, D1=1.96cm, D2=2.41cm에서 104∼106Ω이었다.Applied voltage 500V, 60 seconds, 20 ± 2 ℃, 65 ± 2% RH, test equipment; TOA SME-8311, D1 = 1.96cm and D2 = 2.41cm were 10 4 ∼ 10 6 Ω.

3) 마찰 전압 측정3) Friction voltage measurement

SIMCO-FMX002 측정기를 사용하였다SIMCO-FMX002 meter was used

[표 1][Table 1]

Figure 112018100817460-pat00001
Figure 112018100817460-pat00001

표 1을 참조하면, 실시예 1 내지 7은 비교예 1에 비하여 치수 변화율이 작은 것을 보여준다. 이는 본원발명에 따른 천연직물 바닥재의 구성을 만족했기 때문임을 알 수 있다. Referring to Table 1, Examples 1 to 7 show that the dimensional change rate is small compared to Comparative Example 1. It can be seen that this is because the composition of the natural fabric flooring according to the present invention was satisfied.

또한, 실시예 1 내지 7, 비교예 1은 전반적으로 표면 저항과 마찰 전압이 낮은 결과를 보여준다. 특히, 대전 방지층에 필러를 포함하는 실시예 3, 4, 7은 다른 예에 비하여 표면 저항이 월등히 낮았다. 이러한 결과는 필러에 의해 천연직물 바닥재의 대전 방지 효과가 향상되었음을 의미한다.In addition, Examples 1 to 7, Comparative Example 1 generally shows a result of low surface resistance and low friction voltage. Particularly, Examples 3, 4, and 7 including fillers in the antistatic layer had significantly lower surface resistance than other examples. These results indicate that the antistatic effect of the natural fabric flooring is improved by the filler.
