최근 원단은 의류용 뿐만 아니라 산업용, 생활용품용으로 그 용도를 확장하고 있다. 그 중 생활소재로서 원단이 스크린용으로 사용되고 있는데, 스크린(screen)은 일반적으로 창가리개용이나 프로젝터의 스크린으로 활용되고 이 중 창가리개용 스크린은 가정, 호텔, 레스토랑 기타 건물 등에서 내부의 사생활 보호 및 태양광 차단을 위해서 사용되고 있는 것을 지칭하는 것으로, 일정 폭의 원단을 제단하고, 롤로 감아서 창문에 고정시켜 사용자가 롤을 풀어서 창문을 가리거나 롤을 감아서 시야를 확보할 수 있도록 만든 제품이다. 이 제품은 롤, 판넬의 형태로 원단을 절단하여 롤 스크린(Roll Screen), 판넬 스크린(Panel Screen),버티칼 등의 명칭으로 불리고 있다.Recently, the fabric is expanding its use not only for clothing but also for industrial and household goods. Among them, fabrics are used for screens as living materials. Screens are generally used as window screens or screens of projectors. Among them, screen screens are used for protecting privacy inside homes, hotels, restaurants and other buildings. It refers to what is being used for sun protection. It is a product made by cutting a certain width of fabric, winding it with a roll and fixing it to a window so that the user can unwind the roll to cover the window or wind the roll to secure a field of view. This product is called roll roll, panel screen, vertical, etc. by cutting the fabric in the form of rolls and panels.
상기 스크린 원단은 장폭으로 사용되는 관계로 경직성을 부여해야 한다. 이를 위하여 종래 스크린 원단의 표면을 폴리우레탄계 수지를 이용하여 코팅하여 원단 특유의 유연성을 확보하면서 경직성을 부여하여 왔다. The screen fabric should be given rigidity as it is used in long width. To this end, by coating the surface of the conventional screen fabric using a polyurethane-based resin has been given rigidity while ensuring the unique flexibility of the fabric.
그러나 상기와 같은 방법은 공정상 코팅공정이 추가되어야 하고, 스크린 원단은 댁내에서 설치되고 사용되는 특성상 코팅물질이 VOC로 취급되어 실내환경오염의 문제를 야기하고 있다. However, in the above method, the coating process must be added in the process, and the screen fabric has a problem of indoor environmental pollution because the coating material is treated as VOC due to the characteristics of being installed and used in the house.
본 발명자들은 한편 폴리에스테르 섬유에 주목하는데 이는 상기 섬유의 물성이 강도가 높고, 내약품성이 있으며, 250 내지 255 ℃ 범위의 융점을 지녀 내열성이 우수하며, 신장 굴곡에 대하여는 탄성을 지니는 장점이 있어서 신사복지, 셔츠 등의 의류뿐만 아니라 산업용 재료로 용도가 다양하다는 점에 주목하였다. The inventors, on the other hand, pay attention to polyester fibers, which have high strength, chemical resistance, excellent melting resistance in the range of 250 to 255 ° C., excellent heat resistance, and elasticity against extension bending. In addition to clothing such as welfare and shirts, it was noted that there are various uses for industrial materials.
그러나, 상기의 폴리에스테르는 비교적 융점이 높아 일반적으로 섬유 구조체를 경화시킬 때는 포르말린(포름알데히드 수용액)이라든가 유기용제를 함유한 접착제, 경질 수지(페놀 수지, 멜라닌 수지, 우레아 수지)를 사용한다. 이러한 유기 용제를 함유한 접착제는 원단의 내부까지 침투하지 않아 접착성도 낮고 완성되었을 때의 촉감이 거칠다. 또한, 휘발성이 강하고 인체에 유해한 물질이 대부분이며, 유독 가스 배출 등의 환경적으로 문제가 되어 왔다. However, the polyester has a relatively high melting point and generally uses a formalin (formaldehyde aqueous solution) or an adhesive containing an organic solvent and a hard resin (phenol resin, melanin resin, urea resin) when curing the fiber structure. The adhesive containing such an organic solvent does not penetrate to the inside of the fabric, so the adhesiveness is low and the touch when finished is rough. In addition, most of the substances are highly volatile and harmful to the human body, and have been an environmental problem such as toxic gas emissions.
한편 이러한 문제점을 개선하기 위하여 저융점사를 포함시켜 제직된 원단을 열처리하여 상기 저융점사를 원단에 융착시킴으로서 코팅공정을 생략할 수 있는 기술이 제안되었다. 이러한 방식은 종래 코팅방식의 문제점을 개선할 수 있는 장점이 있기는 하나, 융착율에 따른 물성제어가 검토되지 못하여 다양한 제품군을 형성하지 못하고 필요한 용도에 따른 물성을 보유하지 못하는 문제점이 있다.On the other hand, in order to improve this problem, a technique has been proposed that can omit the coating process by fusing the low-melting point yarn to the fabric by heat-treating the woven fabric including the low-melting point yarn. Although this method has an advantage of improving the problems of the conventional coating method, there is a problem in that the physical property control according to the fusion rate is not examined and thus it is not possible to form various product groups and retain the physical properties according to the required use.

First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.
본 명세서에서 사용되는 정도의 용어 "약", "실질적으로" 등은 언급된 의미에 고유한 제조 및 물질 허용오차가 제시될 때 그 수치에서 또는 그 수치에 근접한 의미로 사용되고, 본 발명의 이해를 돕기 위해 정확하거나 절대적인 수치가 언급된 개시 내용을 비양심적인 침해자가 부당하게 이용하는 것을 방지하기 위해 사용된다.As used herein, the terms "about", "substantially", and the like, are used at, or in close proximity to, numerical values when manufacturing and material tolerances inherent in the meanings indicated are intended to aid the understanding of the invention. Accurate or absolute figures are used to assist in the prevention of unfair use by unscrupulous infringers.
본 명세서서에서 "원단"이라 함은 직물, 편성물, 펠트, 프레이트, 부직포, 접착직물, 몰드직물, 웹(web) 모두를 의미하는 용어로 사용된다. As used herein, the term "fabric" is used as a term meaning all of woven fabrics, knitted fabrics, felts, plates, nonwoven fabrics, adhesive fabrics, mold fabrics, webs.
본 발명에 의한 원단은 일반사와 저융점사가 혼합되어 형성될 수 있다. 우선 일반사는 제한없이 사용될 수 있으며 저융점사는 시스-코어형 또는 분할형 복합섬유가 비제한적인 예로서 사용될 수 있다. 상기 저융점사는 저융점사만으로 경사 및/또는 위사에 사용될 수 있고, 상기 저융점사와 일반사가 혼방 및/또는 합사된 사를 사용할 수 있다. The fabric according to the present invention may be formed by mixing a general yarn and a low melting point yarn. First, general yarns may be used without limitation, and low melting point yarns may be used as non-limiting examples of cis-core or split composite fibers. The low melting point yarn may be used for warp and / or weft only with low melting point yarn, and the low melting point yarn and the general yarn may be mixed and / or spun yarn.
또한 상기 저융점사는 비제한적인 예로서 시스부에는 저융점 폴리에스테르계 수지가, 코어부에는 난연성 폴리에스테르계 수지가 포함된 난연성 저융점 폴리에스테르계 필라멘트일 수 있다. 이 경우 상기 폴리에스테르계 수지는 폴리에틸렌테레프탈레이트 및 폴리부틸렌테레프탈레이트 수지로 이루어진 군에서 1 이상 선택된 것일 수 있으며, 상기 저융점 폴리에스테르계 수지는 이소프탈산 성분, 테레프탈산 성분, 에틸렌글리콜 성분 및 디에틸렌글리콜 성분이 포함된 것일 수 있다. In addition, the low-melting point yarn may be a flame-retardant low-melting point polyester filament including a low-melting point polyester-based resin in the sheath part and a flame-retardant polyester-based resin in the core part. In this case, the polyester-based resin may be one or more selected from the group consisting of polyethylene terephthalate and polybutylene terephthalate resin, the low-melting polyester-based resin isophthalic acid component, terephthalic acid component, ethylene glycol component and diethylene It may include a glycol component.
또한 상기 폴리에스테르계 수지는 융점이 220 ℃ 내지 260 ℃일 수 있으며, 상기 저융점 폴리에스테르계 수지의 융점은 110 내지 200 ℃ 일 수 있다. 상기 범위 미만인 경우 폴리에스테르 자체의 형태안정성에 문제가 있고 상기 범위를 초과하는 경우 코어부의 수지에도 영향을 미칠 수 있다. 상기 시스부 대 코어부의 비는 10:90 내지 30:70 중량%임이 바람직한데 상기 시스부가 10 중량% 미만인 경우에는 열접착성능의 저하를 초래하며, 시스부가 30 중량%를 초과하면 심부의 함량이 너무 줄어들게 되어 폴리에스테르의 섬유 특성이 현저히 저하되고, 난연 특성 발휘가 어렵게 된다.Further, the polyester resin may have a melting point of 220 ° C. to 260 ° C., and a melting point of the low melting polyester resin may be 110 to 200 ° C. If it is less than the above range there is a problem in the morphological stability of the polyester itself and if it exceeds the above range may affect the resin of the core portion. The ratio of the sheath portion to the core portion is preferably 10:90 to 30: 70% by weight. If the sheath portion is less than 10% by weight, the thermal adhesion performance is lowered. It becomes too small and the fiber property of polyester falls remarkably, and it becomes difficult to exhibit a flame-retardant property.
상기 난연성 폴리에스테르계 수지는 인계 난연제와 공중합되어 있기 것이 바람직하며, 더욱 바람직하게는 하기 화학식 1로 표시된 인계 난연제일 수 있다. 이 경우 상기 인계 난연제는 폴리에스테르계 수지 내에 인 원자(P)가 5,000 ppm 내지 10,000 ppm 포함됨이 바람직하다. 상기 인의 함량이 5,000 ppm 미만 되도록 첨가 시에는 난연 효과가 미미하고, 10,000 ppm 초과되면 폴리에스테르계 수지의 용융점도가 저하되어, 방사 시 작업성 및 물성이 저하되는 문제가 있다.The flame retardant polyester-based resin is preferably copolymerized with a phosphorus flame retardant, more preferably may be a phosphorus flame retardant represented by the following formula (1). In this case, it is preferable that the phosphorus flame retardant contains 5,000 ppm to 10,000 ppm of phosphorus atom (P) in the polyester resin. When added so that the phosphorus content is less than 5,000 ppm, the flame retardant effect is insignificant, and if it exceeds 10,000 ppm, the melt viscosity of the polyester-based resin is lowered, there is a problem that the workability and physical properties during spinning.

단, R1 및 R2는 탄소(C)수 1 내지 18 개의 알킬기, 아릴기, 모노히드록시 알킬기 또는 수소 원자이며, R3는 탄소수 1 내지 18 개의 알킬기, 아릴기이다. 또한, n은 1 내지 4 인 정수.However, R1 and R2 are a C1-C18 alkyl group, an aryl group, a monohydroxy alkyl group, or a hydrogen atom, R3 is a C1-C18 alkyl group, an aryl group. In addition, n is an integer of 1-4.
상기 원단을 형성할 원사가 준비되면, 미리 결정된 원단의 설계에 따라 제직 또는 제편될 수 있다. 상기 원단을 형성함에 있어서, 일반사와 저융점사는 50 : 50 내지 75 : 15 중량비로 원단에 포함될 수 있다. 한편 저융점사가 일반사와 혼방 내지 합사되어 상기 일반사와 함께 제직 또는 제편되는 경우 상기 혼방 내지 합사되는 일반사와 저융점사의 비율은 70 : 30 내지 0 :100 중량비로 포함될 수 있다. 상기 일반사와 저융점사가 0 : 100 중량비인 경우 혼방 내지 합사가 아닌 저융점사 단독으로 사용되는 것을 의미한다. When the yarn to form the fabric is prepared, it can be woven or woven according to the design of the predetermined fabric. In forming the fabric, the general yarn and the low melting point yarn may be included in the fabric in a weight ratio of 50:50 to 75:15. On the other hand, when the low-melting point yarns are mixed or filamented with the general yarns to be woven or woven together with the normal yarns, the ratio of the mixed and spun yarns to the low-melting point yarns may be included in a weight ratio of 70:30 to 0: 100. When the general yarn and the low melting point yarn is in a weight ratio of 0: 100, it means that the low melting point yarn is used alone, not mixed or pulverized yarn.
상기 제직 또는 제편을 통해 형성된 원단은 경직성으로 부여하여 위해 저융점사를 융착시키는 공정을 거치게 된다. 이 때 저융점사가 섬유간에 융착되어 원단에 경직성 내지 형태안정성을 부여하는 정도(융착율)는 직조된 원단의 단면을 수직(저융점사가 위사로 제공된 경우에는 위사방향)으로 절개하고, 이를 고정시킨 후 전자 현미경을 이용하고, 200배 배율로 직물의 단면군을 관찰하여 이 중 무작위로 200개를 추출하고 이 범위내에서 섬유간에 융착하고 있는 수를 카운팅함으로서 융착하고 있는 섬유의 수를 산출한다. 이를 백분율로 표시한다. The fabric formed through the weaving or knitting is subjected to a process of fusing low-melting point yarns to impart rigidity. At this time, the low melting point yarn is fused between fibers to impart rigidity or form stability to the fabric (fusion rate). The cross section of the woven fabric is cut vertically (when the low melting point yarn is provided as a weft yarn) and then fixed. Then, using an electron microscope, the cross-sectional group of fabrics was observed at 200 times magnification, and 200 of them were randomly extracted, and the number of fused fibers was calculated by counting the number of fusions between the fibers within this range. This is expressed as a percentage.
본 발명의 일실시예에 의한 원단의 융착율은 다양한 제품군에 제공될 수 있도록 30 내지 100%일 수 있다. 그리고 상기 범위의 융착율을 갖는 원단의 경우 실미끄러짐 정도가 0.1 내지 2.5mm이며, 올풀림강도의 경우 1올 기준 0.2 내지 3.5Kg, 5mm 기준 10 내지 35Kg일 수 있다. 또한 원단의 굽힘길이는 3 내지 10cm일 수 있다.Fusion rate of the fabric according to an embodiment of the present invention may be 30 to 100% to be provided in a variety of products. And in the case of the fabric having a fusion rate in the above range the degree of slippage is 0.1 to 2.5mm, in the case of the pull-up strength may be 0.2 to 3.5Kg per 1ol, 10 to 35Kg based on 5mm. In addition, the bending length of the fabric may be 3 to 10cm.
상기 미끄럼 길이는 원단의 경사 또는 위사가 직물의 표면 또는 이면에 가해지는 마찰 등 물리적 작용에 의하여 부분적으로 경사 또는 위사의 교차 위치가 한 쪽으로 치우치거나 밀린 상태에서의 길이를 의미한다. 일반 직물의 경우 경사 및 위사 간에 커버팩터(cover factor)에 의한 결합력이 존재하여 물리적 결합력으로서 직물의 형태안정성을 확보하지만 본 발명에 의한 원단은 이와 더불어 각각 경사 및/또는 위사의 융착율을 확보하여 직물의 형태안정성을 더 확보할 수 있다.(도 4 참조)The sliding length means a length in which the inclined or weft yarns are partially biased or pushed to one side by physical action such as friction applied to the surface or the back of the fabric. In the case of general fabrics, there is a binding factor between the warp and the weft by the cover factor (cover factor) to secure the shape stability of the fabric as a physical bonding force, but the fabric according to the present invention to secure the fusion rate of the warp and / or weft respectively The shape stability of the fabric can be further secured (see Fig. 4).
한편 상기 올풀림강도라 함은 원단에서 직조된 경사 또는 위사가 원단의 구성으로부터 이탈되는 때의 강도를 의미한다. 즉 올풀림강도가 크다는 것은 직조된 원사가 저융점사와 융착되는 정도가 큼을 의미한다. 이는 원단이 스크린 또는 블라인드 용도로서 장폭 또는 장길이의 사용상태에 있어서 형태안정성이 확보되는 것을 의미한다. Meanwhile, the fold-up strength refers to the strength when the warp or weft yarn woven from the fabric is separated from the fabric. In other words, the high pull-up strength means that the woven yarn has a high degree of fusion with the low melting point yarn. This means that the fabric is secured to form stability in the use state of the long width or long length for screen or blind use.
또한 본 발명에 의한 원단의 굽힘길이는 3 내지 10cm일 수 있다. 굽힘길이는 후술된 시험방법에 의해 평가될 수 있는데, 본 발명에 의한 원단의 굽힘길이는 통상의 원단의 굽힘길이와 일정 차이를 나타내기는 하나 굽힘성이 발현되어 원단으로서의 유연성이 확보될 수 있다. 상기 굽힘길이가 과도하게 길 경우에는 결국 원단으로서의 유연성이 결여되어 가공공정에 어려움이 있고 블라인드 등의 용도로서 부적합한 문제점이 있다.In addition, the bending length of the fabric according to the present invention may be 3 to 10cm. The bending length can be evaluated by the test method described below, but the bending length of the fabric according to the present invention shows a certain difference from the bending length of a conventional fabric, and the flexibility can be ensured because the bending property is expressed. If the bending length is excessively long, there is a lack of flexibility as a fabric, and thus, there is a difficulty in the processing process, and there is a problem that is unsuitable as a blind or the like.
상기 원단의 물성이 상기 범위 내에 포함되는 경우 스크린/블라인드용으로서 적절한 형태안정성이 부여되고 롤링(블라인드지로 사용되는 경우 원단이 감길 수 있어야 함)에도 큰 문제가 없다. 즉 본 발명에 의한 원단에 있어서 상기와 같은 물성의 영역은 스크린용으로서의 형태안정성과 원단으로서 유연성이란 모순된 물성을 동시에 만족할 수 있는 바람직한 영역이라 할 수 있다. When the physical properties of the fabric are included in the above range, appropriate form stability is given for screen / blinds, and there is no big problem in rolling (when used as blind paper, the fabric can be wound). That is, in the fabric according to the present invention, the above-described physical properties may be regarded as a preferable region that can simultaneously satisfy the contradictory physical properties of the shape stability for the screen and the flexibility as the fabric.
한편 본 발명의 일실시예에 의한 원단은 난연성 이외에 내광 견뢰도를 우수하게 하기 위해 벤조트리아졸계, 벤조페논계 등의 자외선 흡수제나 다른 섬유용 가공제를 사용할 수도 있다. 상기 사용될 수 있는 다른 섬유용 가공제로서 일반적으로 사용되는 대전방지제, 발수발유제, 오염방지제, 항균제, 수분 흡수제, 슬립 방지제 등이 부가적으로 사용될 수도 있으며 이러한 일반적으로 공지된 가공제가 부가된다 하더라도 본 발명의 본질적인 발명의 사상을 벗어나지 않는 한 본 발명의 범주에 포함됨은 물론이다.On the other hand, the fabric according to an embodiment of the present invention may use ultraviolet absorbers such as benzotriazole-based, benzophenone-based and other processing agents for fibers in order to improve the light fastness in addition to flame retardancy. Antistatic agents, water and oil repellents, antifouling agents, antibacterial agents, moisture absorbents, anti slip agents, and the like, which are generally used as other textile processing agents that may be used, may additionally be used, even if such commonly known processing agents are added. Of course, it is included in the scope of the present invention without departing from the spirit of the invention.
한편 본 발명에 의한 원단은 난연사와 저융점사로 형성된 원단으로 제조될 수 있다. 이 경우 상기 저융점사는 경사 및 위사 또는, 경사 또는 위사에 포함되거나 상기 난연사와 저융점사가 혼방 또는 합사되어 경사 및 위사 또는, 경사 또는 위사에 포함될 수 있다. 기타 물성과 융착율은 상기 일반사와 저융점사로 형성된 원단과 동일할 수 있다.Meanwhile, the fabric according to the present invention may be made of a fabric formed of flame retardant yarn and low melting point yarn. In this case, the low melting point yarn may be included in warp and weft yarns, or inclined or weft yarns, or the flame retardant yarn and low melting point yarns may be mixed or plyed together and included in the inclined and weft yarns, or inclined or weft yarns. Other physical properties and fusion rate may be the same as the fabric formed of the general yarn and low melting point yarn.

* 시험방법* Test Methods
1. 실미끄러짐 길이 측정 : KSK 04081.Slip slip length measurement: KSK 0408
2. 올풀림 강도2. Unfolding strength
(1) 한 올 풀림강도(1) one full unfolding strength
시료 크기 7X7(cm)을 준비하고 이 중 한올을 빼서 1 cm만큼 풀어내어 인장시험기(KSK 0520)에 물린 후 나머지 6 cm에 잔존하는 시료내의 한 올이 다 풀려나갈때 까지 필요한 하중을 측정하였다. 이 때 조직밀도는 100X100(가닥/inch)으로 일치시켰다.A sample size of 7 × 7 (cm) was prepared, one of which was taken out, 1 cm was taken out, and the bite tester (KSK 0520) was bitten by a tensile tester (KSK 0520). At this time, the tissue density was matched to 100 × 100 (strands / inch).
(2) 5mm 올풀림 강도 (2) 5mm pull up strength
시료 크기 7X7(cm)을 준비하고 준비한 시료의 가운데 윗변에서 5미리 위치에 후크를 걸어 끼운다. 상기 후크는 60 Kg이상의 힘에도 형태변화가 없는 재질을 사용한다. 상기 후크를 인장시험기 윗부분에 , 원단은 아래쪽에 파지 한 후 하중을 가하면서 5 mm 만큼의 올이 원단에서 분리될 때 까지 필요한 하중 측정한다. 이 때 올이 분리되지 않고 원단 파열이 일어날 경우 파열 시점의 하중을 데이타로 간주한다. 측정 중에 가해진 하중 중 최대치를 물성 수치로 평가한다. 이 때 조직밀도는 100X100(가닥/inch)으로 일치시켰다.Prepare a sample size of 7X7 (cm) and hook it into position 5 mm from the top of the center of the prepared sample. The hook uses a material that does not change shape even when the force of more than 60 Kg. The hook is placed on the upper part of the tensile tester, the fabric is held underneath, and the load is measured while the load is applied until the oval of 5 mm is separated from the fabric. In this case, if the fabric does not separate and the fabric breaks, the load at the time of break is considered as data. The maximum value of the loads applied during the measurement is evaluated by the property value. At this time, the tissue density was matched to 100 × 100 (strands / inch).
3. 원단의 굽힘길이3. Bending length of the fabric
시료 크기 7X7(cm)을 준비하고 일단을 플랫폼의 긴 방향에 대하여 평행하게 되도록 플랫폼 위에 위치시킨다. 늘어진 부분이 플랫폼에서 돌출되어 자체 하중에 의하여 굽어지도록 플랫폼의 길이 방향으로 전진시킨다. 돌출된 부분의 끝은 자유롭고 다른 쪽은 적당한 압력으로 시료가 미끄러지도록 한다. 시료의 앞 끝이 플랫폼 앞 끝에서 연속되는 선을 지나 수평면 이하 41.5°의 각도로 기울어지면, 돌출길이는 시료의 굽힘길이의 두배가 된다.Prepare a sample size 7 × 7 (cm) and place one end on the platform to be parallel to the long direction of the platform. The drooping part protrudes from the platform and advances in the longitudinal direction of the platform to bend under its own load. The tip of the protruding part is free and the other side allows the sample to slide under moderate pressure. If the leading end of the sample is inclined at an angle of 41.5 ° below the horizontal plane through a continuous line at the front end of the platform, the protruding length is twice the bending length of the sample.
상기 실시예의 시험결과는 하기 표 2로 정리하였다. 하기 표 2에 나타난 것과 같이 본 발명에 의한 실시예들은 일반 원단(비교예 3)은 물론 비교예들에 비해 원단의 융착상태가 우수하여 직조된 원사가 탈리되지 않음을 알 수 있다. 즉 이는 원단의 경직성으로 발현되어 용도별로 선택에 따라 적절한 융착율 및 저융점사의 혼용율을 가변하여 경직성을 제어할 수 있다. 한편 도 3 및 4는 본 발명의 실시예에 의한 원단의 단면 SEM 사진이고, 도 5는 비교예에 의한 원단의 단면 SEM 사진이다. Test results of the above examples are summarized in Table 2 below. As shown in Table 2, the examples according to the present invention can be seen that the woven yarn is not detached due to the excellent fusion state of the fabric as compared to the general fabric (Comparative Example 3) as well as the comparative examples. In other words, it is expressed in the rigidity of the fabric can be controlled by varying the appropriate fusion rate and the mixing ratio of the low melting point yarn according to the selection for each use. 3 and 4 are cross-sectional SEM photographs of the fabric according to the embodiment of the present invention, and FIG. 5 is a cross-sectional SEM photograph of the fabric according to the comparative example.
