Abstract
Description
本發明係關於一種紡織工具,其包含一工作區段及一固持區段,在該工作區段中,該紡織工具具有用於接納一絲線之一絲線切孔,該固持區段用於在一紡織機中固持及/或移動該紡織工具。該固持區段可例如用於在一紡織機中附裝及/或移動該紡織工具。本發明亦係關於該紡織工具之用途及其製作方法。The present invention relates to a textile tool, which includes a working section and a holding section. In the working section, the textile tool has a thread cut hole for receiving a thread, and the holding section is used for a thread cutting hole. The textile tool is held and/or moved in the textile machine. The holding section can be used, for example, for attaching and/or moving the textile tool in a textile machine. The invention also relates to the use of the textile tool and its manufacturing method.
舉例而言,可能的紡織工具係為機器針,例如機器縫紉針、機器編織針、機器簇絨針等。此等針會經受高應力。舉例而言,一機器編織針在編織含有磨蝕性紗線之工業用紡織品(technical textile)期間會經歷高度磨損。縫紉針及/或簇絨針亦可因在紡織品生產過程期間該針所刺穿過的硬材料或磨蝕性材料而經受高度磨損。For example, possible textile tools are machine needles, such as machine sewing needles, machine knitting needles, machine tufting needles, and so on. These needles are subject to high stress. For example, a machine knitting needle experiences a high degree of wear during the knitting of technical textiles containing abrasive yarns. Sewing needles and/or tufting needles can also undergo a high degree of wear due to the hard or abrasive materials that the needle pierces through during the textile production process.
DE 101 26 118 A1闡述一種耐磨件(wear part),該耐磨件包含具有一薄磨損防護層之一基礎材料或一芯材料。視需要,磨損防護層與芯材料之間可存在一中介層(mediator layer)。舉例而言,該磨損防護層可係為一類金剛石碳(diamond-like carbon;DLC)塗層。此外,可將一覆蓋層施加至磨損防護層。耐磨組件亦可係為一絲線承載元件。DE 101 26 118 A1 describes a wear part comprising a base material or a core material with a thin wear protection layer. If necessary, there may be a mediator layer between the wear protection layer and the core material. For example, the wear protection layer may be a diamond-like carbon (DLC) coating. In addition, a cover layer can be applied to the wear protection layer. The wear-resistant component can also be a thread-bearing component.
自這一點出發,本發明之目標可被視為提供一種改良之經耐磨性最佳化之紡織工具,該紡織工具具有用於接納一絲線之一絲線切孔(thread cut-out)。From this point of view, the object of the present invention can be regarded as providing an improved textile tool optimized for abrasion resistance, the textile tool having a thread cut-out for receiving a thread.
此目標係藉由一種具有如請求項1所述之特徵之紡織工具、一種具有如請求項15所述之特徵之使用方法及一種具有如請求項16所述之特徵之製作方法來達成。This goal is achieved by a textile tool with the characteristics described in claim 1, a use method with the characteristics described in
根據本發明之紡織工具包含用於在一紡織機中固持及/或移動該紡織工具之一固持區段。該固持區段亦可用於例如在紡織機之運作期間使紡織工具移動。此外,該紡織工具包含具有一絲線切孔之一工作區段。將一欲被加工之絲線***或穿入絲線切孔中。絲線切孔較佳具有一環形閉合設計,且在各對置側上具有一相應開口或孔口。The textile tool according to the present invention includes a holding section for holding and/or moving the textile tool in a textile machine. The holding section can also be used, for example, to move the textile tool during the operation of the textile machine. In addition, the textile tool includes a working section with a thread cut hole. Insert or thread a thread to be processed into the thread cutting hole. The thread cut hole preferably has an annular closed design, and has a corresponding opening or orifice on each opposite side.
舉例而言,根據本發明之紡織工具可係為一機器編織針、一機器縫紉針或一機器簇絨針。在機器編織針之情形中,絲線切孔可係由一通孔(例如一眼子針(eye-pointed needle)中)或由可被一可移動元件(例如一舌片或滑件)閉合之區域內側之鉤形成。在一機器縫紉針或一機器簇絨針之情形中,絲線切孔係由針之特定孔眼形成。For example, the textile tool according to the present invention can be a machine knitting needle, a machine sewing needle or a machine tufting needle. In the case of machine knitting needles, the thread cut hole can be made by a through hole (for example in an eye-pointed needle) or by a movable element (for example, a tongue or slider) inside an area that can be closed The hook is formed. In the case of a machine sewing needle or a machine tufting needle, the thread cut hole is formed by the specific hole of the needle.
該紡織工具包含由一芯材料製成之一工具芯。舉例而言,可使用一金屬材料或一金屬合金作為該芯材料。在一個實例性實施例中,使用一鋼合金作為該芯材料。The textile tool includes a tool core made of a core material. For example, a metal material or a metal alloy can be used as the core material. In an exemplary embodiment, a steel alloy is used as the core material.
一磨損防護層在包含絲線切孔在內之工作區段中被施加至工具芯。該磨損防護層係由不同於芯材料之一材料製成。該磨損防護層之硬度較佳大於芯材料之硬度。該磨損防護層在一仍未使用之紡織工具之工作區段中完全覆蓋工具芯。具體而言,該磨損防護層存在於一前端與絲線切孔間之一前端區段中以及工作區段之絲線切孔之區域中。該磨損防護層係由不同於芯材料之一材料製成,且例如可係由一氧化鋁層、一碳層、一類金剛石碳層、一碳化物層(例如一碳化鈦層(titanium carbide layer;TiC))或一氮化物層(例如一氮化鋁鈦層(aluminum titanium nitride layer;AlTiN)或一碳氮化鈦層(titanium carbon nitride layer;TiCN))形成。舉例而言,類金剛石碳層可係為含碳非晶碳層(a-C:H)。A wear protection layer is applied to the tool core in the working section including the wire cut hole. The wear protection layer is made of a material different from the core material. The hardness of the wear protection layer is preferably greater than the hardness of the core material. The wear protection layer completely covers the tool core in a working section of a textile tool that has not yet been used. Specifically, the wear protection layer exists in a front end section between a front end and the thread cut hole and in the area of the thread cut hole in the working section. The wear protection layer is made of a material different from the core material, and may be, for example, an aluminum oxide layer, a carbon layer, a diamond-like carbon layer, and a carbide layer (for example, a titanium carbide layer; TiC) or a nitride layer (for example, an aluminum titanium nitride layer (AlTiN) or a titanium carbon nitride layer (TiCN)) is formed. For example, the diamond-like carbon layer may be a carbon-containing amorphous carbon layer (a-C:H).
磨損防護層上至少局部地存在一更淺顏色之覆蓋層。該覆蓋層至少存在於紡織工具之工作區段內絲線切孔之區域中。該覆蓋層覆蓋絲線切孔之內部以及工作區段的與絲線切孔之邊緣直接毗連之外表面區域。在絲線切孔之區域中施加一更淺顏色之覆蓋層會簡化將一絲線***或穿入絲線切孔中之操作。與一絲線或紗線之粗度相較,絲線切孔(例如,一針之一孔眼)經常係為相對小的,以致難以將絲線穿入。藉由在絲線切孔中及在絲線切孔上給磨損防護層塗覆一覆蓋層,穿線操作得以簡化。更淺顏色之覆蓋層會簡化對絲線切孔或其界限之視覺識別。由於絲線與切孔之接觸,切孔中可能會發生對覆蓋層之移除。切孔周圍之覆蓋層得以保留,且已發現:結果,儘管切孔中存在此種移除,即使在一用過之紡織工具上仍能簡化穿線操作。A lighter colored covering layer is at least partially present on the wear protection layer. The covering layer is present at least in the area of the thread cut holes in the working section of the textile tool. The covering layer covers the inside of the thread cut hole and the outer surface area of the working section directly adjacent to the edge of the thread cut hole. Applying a lighter colored covering layer in the area of the thread cut hole will simplify the operation of inserting or threading a thread into the thread cut hole. Compared with the thickness of a thread or yarn, the thread cut holes (for example, a hole in a needle) are often relatively small, making it difficult to penetrate the thread. By applying a covering layer to the wear protection layer in the thread cut hole and on the thread cut hole, the threading operation can be simplified. A lighter color covering will simplify the visual recognition of the thread cut holes or their boundaries. Due to the contact between the thread and the cut hole, removal of the cover layer may occur in the cut hole. The covering layer around the cut hole is retained, and it has been found that, as a result, despite this removal in the cut hole, the threading operation can be simplified even on a used textile tool.
覆蓋層可另外滿足另一功能。其可針對紡織工具與另一部件(例如紡織機之一組件或另一紡織工具)之一錯誤相對定位或錯誤相對定向用作一指示層。若紡織工具與另一部件之間出現不良接觸,則在接觸區中覆蓋層會被移除。基於接觸區周圍之覆蓋層與位於覆蓋層下方之磨損防護層間之淺淡差異,可在視覺上輕易地偵測出此等接觸區,其中在接觸區中,磨損防護層係變得可看到。隨後,可在發生會減損使用壽命之磨損之前及時地對紡織工具或另一部件進行正確調整。The cover layer can additionally fulfill another function. It can be used as an indicator layer for an incorrect relative positioning or incorrect relative orientation of a textile tool and another component (for example, a component of a textile machine or another textile tool). If there is a bad contact between the textile tool and another component, the covering layer will be removed in the contact area. Based on the slight difference between the covering layer around the contact area and the wear protection layer located below the covering layer, these contact areas can be easily detected visually. In the contact area, the wear protection layer becomes visible . Subsequently, the textile tool or another component can be adjusted correctly in time before wear that would reduce the service life.
此外,具備覆蓋層之區域之表面可具有較磨損防護層之表面低之一粗糙度,藉以使將一絲線***或穿入絲線切孔中之操作得以簡化。In addition, the surface of the area with the covering layer can have a lower roughness than the surface of the wear protection layer, so that the operation of inserting or threading a thread into the thread cut hole can be simplified.
磨損防護層可係藉由沉積方式(例如一物理製程或一化學製程,例如一物理氣相沉積(physical vapor deposition;PVD)製程、一化學氣相沉積(chemical vapor deposition;CVD)製程或一電漿輔助化學氣相沉積(plasma assisted chemical vapor deposition;PACVD)製程)而施加至工具芯。The wear protection layer may be deposited by a deposition method (for example, a physical process or a chemical process, such as a physical vapor deposition (PVD) process, a chemical vapor deposition (CVD) process, or an electrical process). A plasma assisted chemical vapor deposition (PACVD process) is applied to the tool core.
覆蓋層同樣係藉由一物理方法或一化學方法(例如,藉由一霧化方法(「濺鍍」))而施加至磨損防護層。此亦可有利於在一共用塗覆裝置中或在塗覆裝置之一單個室(例如一真空室)中連續地製作磨損防護層及覆蓋層。The cover layer is also applied to the wear protection layer by a physical method or a chemical method (for example, by an atomization method ("sputtering")). This can also facilitate the continuous production of the wear protection layer and the cover layer in a common coating device or in a single chamber of the coating device (such as a vacuum chamber).
紡織工具之工作區段較佳直接毗連紡織工具之一前端。使工作區段的與紡織工具之前端毗連之一前端區域無覆蓋層係為有利的。可例如在覆蓋層已被施加至磨損防護層之後例如藉由一機械製程(例如拋光)在前端區域中將該覆蓋層再次移除。例如在一機器縫紉針或一機器簇絨針之情形中,此前端區域會在對一紡織材料之刺穿期間經受特別高之磨損,以致覆蓋層將受紡織材料磨蝕,且紡織材料中將會保留覆蓋層之顆粒。此會藉由在前端區域中省卻或移除覆蓋層而得以避免。The working section of the textile tool is preferably directly adjacent to a front end of the textile tool. It is advantageous to leave a front end region of the working section adjacent to the front end of the textile tool without a covering layer. The cover layer can be removed again in the front end region, for example, after the cover layer has been applied to the wear protection layer, for example by a mechanical process (eg polishing). For example, in the case of a machine sewing needle or a machine tufting needle, the front end area will experience extremely high wear during the piercing of a textile material, so that the covering layer will be abraded by the textile material, and the textile material will be Keep the particles of the covering layer. This can be avoided by omitting or removing the cover layer in the front end area.
工作區段之前端區域可具有較工作區段之其餘區域低之一粗糙度。舉例而言,可藉由拋光來達成此更低粗糙度。舉例而言,藉由降低前端區域之粗糙度,可降低一機器針(縫紉針或簇絨針)之刺穿力。藉由降低粗糙度(例如,拋光),亦可移除在工作區段已被塗覆之後存在之覆蓋層。The front end region of the working section may have a roughness lower than that of the rest of the working section. For example, this lower roughness can be achieved by polishing. For example, by reducing the roughness of the front end area, the piercing force of a machine needle (sewing needle or tufting needle) can be reduced. By reducing the roughness (for example, polishing), it is also possible to remove the covering layer that exists after the working section has been coated.
此外,使磨損防護層之層厚度在一縱向方向上變化係為有利的。例如,磨損防護層之厚度在前端區域中較在工作區段的與前端區域在一縱向方向相對定位之一後部區域中或較在固持區段中可更大。使固持區段之至少一部分無磨損防護層及覆蓋層亦係為較佳的。In addition, it is advantageous to vary the layer thickness of the wear protection layer in a longitudinal direction. For example, the thickness of the wear protection layer may be greater in the front end area than in a rear area of the working section that is positioned opposite to the front end area in a longitudinal direction or in the holding section. It is also preferable to make at least a part of the holding section free of abrasion protection layer and covering layer.
磨損防護層之層厚度及/或覆蓋層之層厚度在絲線切孔內側較在絲線切孔以外可更小。如此一來,作為塗覆之結果,絲線切孔之尺寸不會那麼顯著地改變。在絲線切孔內側磨損防護層之層厚度及/或覆蓋層之層厚度可被選擇成小至足以使覆蓋層及/或磨損防護層在紡織工具之運作期間在絲線切孔之區域中受到機械磨蝕。如此一來,可使對紡織工具之磨損變得能夠在視覺上識別出。首先,覆蓋層被延伸穿過絲線切孔之絲線移除(例如當紡織工具正被使用時),藉以使以下顯而易見:此係為一用過之紡織工具。在僅一極短運作週期之後,絲線切孔內側之覆蓋層即可被移除。若繼續使用,則磨損防護層亦將被移除,藉以使工具芯變得可看到。如此一來,同樣可在視覺上識別出正增長之磨損度。The layer thickness of the wear protection layer and/or the layer thickness of the covering layer may be smaller inside the thread cut hole than outside the thread cut hole. In this way, as a result of the coating, the size of the thread cut hole will not change so significantly. The layer thickness of the wear protection layer and/or the layer thickness of the cover layer on the inner side of the thread cut hole can be selected to be small enough that the cover layer and/or the wear protection layer are mechanically exposed to the thread cut hole area during the operation of the textile tool. Abrasion. In this way, the wear of textile tools can be visually recognized. First, the covering layer is removed by the thread extending through the thread cut hole (for example, when the textile tool is being used), so that the following is obvious: This is a used textile tool. After only a very short operating period, the covering layer inside the thread cut hole can be removed. If you continue to use it, the wear protection layer will also be removed, so that the tool core becomes visible. In this way, the positive growth of wear can also be visually recognized.
在絲線孔眼之區域中,磨損防護層較佳具有0.3微米(μm)至0.8微米(且例如約為0.5微米)之一層厚度。在絲線切孔之區域中,覆蓋層較佳具有小於0.1微米之一層厚度且例如具有0.02微米至0.08微米之一層厚度。In the area of the thread holes, the wear protection layer preferably has a layer thickness of 0.3 micrometers (μm) to 0.8 micrometers (and, for example, about 0.5 micrometers). In the area of the thread cut hole, the covering layer preferably has a layer thickness of less than 0.1 μm and, for example, a layer thickness of 0.02 μm to 0.08 μm.
在一個較佳實例性實施例中,在工作區段以內及在絲線切孔以外磨損防護層之層厚度係為至少1.0微米及/或不大於5.0微米。In a preferred exemplary embodiment, the layer thickness of the wear protection layer within the working section and outside the thread cut hole is at least 1.0 μm and/or not more than 5.0 μm.
使磨損防護層之層厚度在前端區段以內最大係為較佳的。It is better to maximize the layer thickness of the wear protection layer within the front end section.
在紡織工具之工作區段中施加覆蓋層之區域內,覆蓋層之層厚度係為至少0.02微米及/或不大於0.3微米。In the area where the covering layer is applied in the working section of the textile tool, the layer thickness of the covering layer is at least 0.02 μm and/or not more than 0.3 μm.
覆蓋層可係為一金屬層,例如一鉻層。The cover layer can be a metal layer, such as a chromium layer.
圖式例示一紡織工具10,在實例性實施例中,紡織工具10被設計為一機器縫紉針11。該紡織工具亦可由一機器編織針或一機器簇絨針等形成。The figure illustrates a textile tool 10. In the exemplary embodiment, the textile tool 10 is designed as a machine sewing needle 11. The textile tool can also be formed by a machine knitting needle or a machine tufting needle.
紡織工具10在一縱向方向R上沿著一縱向軸線L自一前端12延伸至一後端13。在機器縫紉針11之情形中,前端12係由針尖端14形成。The textile tool 10 extends along a longitudinal axis L in a longitudinal direction R from a front end 12 to a
一工作區段15毗連前端12。一固持區段16毗連後端13。在機器縫紉針11上,固持區段16用於將機器縫紉針11夾緊於一縫紉機之一架座中。在其他紡織工具10中,固持區段16可用以固持及/或移動紡織工具。在實例性實施例中,工作區段15與固持區段16之間存在一過渡區段17,在過渡區段17內,針體之直徑朝向固持區段16而變寬。A working
在工作區段15中,紡織工具10具有一絲線切孔20,在機器縫紉針11之情形中,絲線切孔20係由針眼21形成。在實例性實施例中,絲線切孔20在徑向於縱向軸線L之一貫通方向D上完全穿透紡織工具10。當在圍繞貫通方向D之一圓周方向U上觀看時,絲線切孔20及根據該實例之針眼21完全閉合。絲線切孔20被設置於在平行於縱向軸線L之縱向方向R上距前端12一距離處。In the working
一絲線凹槽23毗連針眼21在機器縫紉針11之一前側22上之一開口,絲線凹槽23在縱向方向R上延伸且在距針尖端14及距針眼21之開口一距離處過渡至工作區段15之外表面中。絲線凹槽23用於在縫紉期間接納及導引一絲線之一區段。A
紡織工具10及根據該實例之機器縫紉針11包含一工具芯30,工具芯30係由一芯材料製成。舉例而言,可使用一金屬合金且較佳使用一鋼合金作為該芯材料。已顯示出:在某些應用中,由一芯材料製成之一紡織工具10並不受到充分磨損防護,例如,當一針刺穿過之材料包含磨蝕性絲線或者需要高刺穿力或高穿透力時。因此,在實例性實施例中,工具芯30在工作區段中具備一磨損防護層31。磨損防護層31在工作區段15中完全覆蓋工具芯30。在實例性實施例中,磨損防護層31亦可至少局部地存在於過渡區段17中或亦可仍存在於末端區段16中。The textile tool 10 and the machine sewing needle 11 according to this example include a
當在縱向方向R上觀看時,磨損防護層31之層厚度在紡織工具10之不同位置中不同,例如在工作區段15內亦如此。在過渡區段17或末端區段16內,該實例性實施例中之磨損防護層31之層厚度在縱向方向R上朝向後端13連續地趨向零減小。When viewed in the longitudinal direction R, the layer thickness of the
舉例而言,可使用一含碳層(例如一類金剛石碳層)作為磨損防護層。可將類金剛石碳層實施為一含氫非晶碳層(a-C:H)。亦可使用其他磨損防護層31,例如碳化物層或氮化物層。舉例而言,磨損防護層31可係為一碳化鈦層、一氮化鋁鈦層、一碳氮化鈦層,或另一選擇為,亦可係為一氧化鋁層等。可以一物理製程或一化學製程(例如,一物理氣相沉積製程、一化學氣相沉積製程、或一電漿輔助化學氣相沉積製程)來施加磨損防護層。根據該實例,磨損防護層31係為電絕緣的。For example, a carbon-containing layer (such as a diamond-like carbon layer) can be used as the wear protection layer. The diamond-like carbon layer can be implemented as a hydrogen-containing amorphous carbon layer (a-C:H). Other
磨損防護層31之層厚度係垂直於工具芯30之表面而測得。在工作區段15的直接毗連前端12之一前端區域15a中,磨損防護層31具有一第一層厚度d1。在絲線切孔20與過渡區域17或固持區段16間之區域中,磨損防護層31具有一第二層厚度d2。在絲線切孔20或針眼21內側,磨損防護層31具有一第三層厚度d3。第一層厚度d1大於第二層厚度d2且大於第三層厚度d3。第三層厚度d3小於第一層厚度d1且小於第二層厚度d2。在絲線切孔20內側,磨損防護層31具有在工作區段15中出現之較低層厚度。The layer thickness of the
在實例性實施例中,第二層厚度d2係為約1.0微米(µm)。第一層厚度d1係為約3.0微米。第三層厚度d3係為約0.5微米。In an exemplary embodiment, the thickness d2 of the second layer is about 1.0 micrometer (µm). The thickness d1 of the first layer is about 3.0 microns. The thickness d3 of the third layer is about 0.5 microns.
至少在工作區段15內絲線切孔20之區域中,磨損防護層31被一覆蓋層32覆蓋。覆蓋層32具有較磨損防護層31淺之一顏色。覆蓋層32在絲線切孔20內側且至少在鄰接絲線切孔20之一區域中覆蓋磨損防護層31。覆蓋層32可完全覆蓋工作區段15中在前端區域15a以外之磨損防護層31。亦可使覆蓋層32至少局部地覆蓋工作區段15以外(例如,過渡區段17中及/或固持區段16中)之磨損防護層31。At least in the area of the thread cut hole 20 in the working
舉例而言,可施加一金屬層(例如一鉻層)來作為覆蓋層32。舉例而言,藉由一霧化方法(「濺鍍」)來施加覆蓋層32。For example, a metal layer (such as a chromium layer) can be applied as the
在直接毗連前端12之前端區域15a中,磨損防護層31無覆蓋層32。於絲線切孔20與前端12之間,僅在前端區域15a以外存在覆蓋層32。前端區域15a於機器縫紉針11上大致在針眼21與針尖端14間之位置處終止,在該位置處,機器縫紉針11在垂直於縱向軸線L之方向上已達到最大尺寸。在實例性實施例中,前端區域15a在針尖端14與穿過縱向軸線L之一徑向平面之間延伸,該徑向平面設置於絲線凹槽23過渡至機器縫紉針11之工作區段15之外表面中之一點處。In the
如上所述,磨損防護層31之層厚度在縱向方向R上改變。覆蓋層32之層厚度亦在縱向方向R上變化。在絲線切孔20內側以及在圍繞絲線切孔20之區域中,覆蓋層32具有一最小層厚度,該最小層厚度大於磨損防護層31之粗糙度。根據該實例,覆蓋層32之最小層厚度係為0.02微米。在絲線切孔20內側,覆蓋層32具有約為0.1微米之一層厚度。在工作區段15中於絲線切孔20以外,覆蓋層32之層厚度更大且係為約0.3微米。前端區域15a中不存在覆蓋層32。As described above, the layer thickness of the
可如下來製作紡織工具10及根據該實例之機器縫紉針11:The textile tool 10 and the machine sewing needle 11 according to this example can be made as follows:
首先,自芯材料製作工具芯30。此後,將紡織工具10之固持區段16設置於一架座中,並以一物理塗覆製程或一化學塗覆製程給紡織工具10塗覆磨損防護層31。此後,給紡織工具10塗覆覆蓋層32,覆蓋層32係被施加至磨損防護層31。First, the
此後,藉由一拋光方法或另一適合之方法來降低前端區域15a中表面之粗糙度。如此一來,可降低機器縫紉針11進入一紡織品之刺穿力。根據該實例,覆蓋層32被再次移除以降低前端區域15a中之粗糙度,或者覆蓋層32係在降低前端區域15a中之粗糙度期間被再次移除。因此,在工作區段15之前端區域15a中,可看到與覆蓋層32相較更暗之磨損防護層。Thereafter, a polishing method or another suitable method is used to reduce the roughness of the surface in the
在絲線切孔20內側,磨損防護層31之層厚度及覆蓋層32之層厚度係如此低以致其在紡織工具10之使用期間會被穿過絲線切孔20之絲線移除。首先,覆蓋層32被機械摩擦移除。此係在已經過一短的使用持續時間之後發生。因此,當在絲線切孔20內側不存在覆蓋層32時,可立即識別出紡織工具10已被使用。在繼續使用一持續時間之情況下,絲線切孔20內側之極薄磨損防護層31亦被與絲線之摩擦機械移除。因此,若絲線切孔20內側亦不再存在一磨損防護層31,則可識別出紡織工具10已被使用一長的週期。如此一來,可在視覺上將未使用之新紡織工具(在絲線切孔20內側存在覆蓋層32)與已使用一短持續時間之紡織工具10(絲線切孔20中之覆蓋層32已被移除,但絲線切孔20中存在磨損防護層31)以及與已被使用一更長週期之紡織工具10(在絲線切孔20內側既不存在覆蓋層32亦不存在磨損防護層31)進行區別。Inside the thread cut hole 20, the layer thickness of the
此外,本發明係關於一種紡織工具10,例如包含一工作區段15及一固持區段16之一機器縫紉針11。在工作區段15中,紡織工具10具有用於接納一絲線之一絲線切孔20。紡織工具10包含由一芯材料製成之一工具芯30。在工作區段15中,紡織工具10塗覆有一磨損防護層31,磨損防護層31不同於工具芯30之芯材料。在絲線切孔20之區域中,磨損防護層31具備一覆蓋層32,覆蓋層32具有較磨損防護層31淺之一顏色。覆蓋層32存在於絲線切孔20內側及鄰接絲線切孔20處。與紡織工具10之一前端12毗連之一前端區域15a較佳保持無覆蓋層32。In addition, the present invention relates to a textile tool 10, for example, a machine sewing needle 11 including a working
