Description

繞線筒及紗線卷裝 Bobbins and yarn packages

本發明是關於繞線筒及紗線卷裝。 The present invention relates to bobbins and yarn packages.

以往，在形成紗線卷裝時，使用捲繞紗線的繞線筒。上述紗線是例如由玻璃纖維所構成的紗線(以下，簡稱為玻璃紗線)，使用於玻璃纖維織物等的製造。 Conventionally, when forming a yarn package, a bobbin in which the yarn is wound is used. The above-mentioned yarn is, for example, a yarn composed of glass fibers (hereinafter, simply referred to as glass yarn), and is used in the production of glass fiber fabrics and the like.

作為上述繞線筒有例如在捲線用圓筒部的周圍，具備沿著圓周方向剖面呈梯形的複數的環狀凸部已為人知(例如，參閱專利文獻1)。 As the above-mentioned bobbin, for example, it is known that a plurality of ring-shaped convex portions having a trapezoidal cross section along the circumferential direction are provided around a cylindrical portion for winding (for example, refer to Patent Document 1).

專利文獻1記載的繞線筒是在上述捲繞部的周圍具備上述複數的環狀凸部，藉此在紗線最內層的解舒時，防止捲繞的薄紗層滑動，解決紗線重疊產生斷紗的問題。 The bobbin described in Patent Document 1 is provided with the above-mentioned plural annular convex parts around the winding part, thereby preventing the wound tissue layer from slipping when the innermost layer of the yarn is unwinding, thereby solving the problem of Overlapping causes yarn breakage.

但是，上述習知的繞線筒中，在捲繞2.7g/km以下極細的玻璃紗線，抽出該玻璃紗線解舒時會有該玻璃紗線斷裂的所謂「無線頭」的現象產生的問題。 However, in the above-mentioned conventional bobbin, when an extremely fine glass yarn of 2.7 g/km or less is wound, and the glass yarn is unwound when the glass yarn is drawn out, there is a problem caused by the so-called "no end" phenomenon in which the glass yarn breaks. .

本發明是以提供消除相關的問題，並可抑制無線頭的產生的繞線筒為目的。 The present invention aims to provide a bobbin that eliminates related problems and can suppress the generation of wireless heads.

為達成相關的目的，本發明的繞線筒是在捲線用圓筒部的周圍，具備沿著該圓筒部的圓周方向剖面呈梯形的複數的環狀凸部的繞線筒，其特徵為：該環狀凸部的高度h為20~200μm的範圍，相鄰的該環狀凸部彼此之中心間距離的間隔d1是在100~9400μm的範圍，相對於該環狀凸部的高度h之相鄰的該環狀凸部彼此的中心間距離的間隔d1的比d1/h為3.4~75.0的範圍。 In order to achieve the related object, the bobbin of the present invention is a bobbin having a plurality of ring-shaped convex portions that are trapezoidal in cross section along the circumferential direction of the cylindrical portion around the cylindrical portion for winding, and is characterized by : The height h of the annular protrusion is in the range of 20 to 200 μm, and the distance d 1 between the centers of adjacent annular protrusions is in the range of 100 to 9400 μm, relative to the height of the annular protrusion The ratio d 1 /h of the interval d 1 of the distance between the centers of the adjacent annular convex portions of h is in the range of 3.4 to 75.0.

根據本發明的繞線筒，上述剖面呈梯形的環狀凸部的高度h為20~200μm的範圍，相鄰的該環狀凸部彼此之中心間距離的間隔d1是在100~9400μm的範圍，相對於該環狀凸部的高度h之相鄰的該環狀凸部彼此的中心間距離的間隔d1的比d1/h為3.4~75.0的範圍，藉此即使在捲繞2.7g/km以下極細的玻璃紗線時，仍可抑制無線頭的產生。 According to the bobbin of the present invention, the height h of the ring-shaped convex portion having a trapezoidal cross-section is in the range of 20 to 200 μm, and the distance d 1 between the centers of adjacent ring-shaped convex portions is 100 to 9400 μm. The ratio d 1 /h of the interval d 1 of the distance between the centers of adjacent ring-shaped convex portions relative to the height h of the ring-shaped convex portion is in the range of 3.4 to 75.0, so that even when winding 2.7 For extremely thin glass yarns below g/km, the production of wireless heads can still be suppressed.

上述環狀凸部的高度h小於20μm時在充分防止捲繞的玻璃紗線捲繞打滑困難，不能抑制無線頭，在超過200μm時玻璃紗線從繞線筒解舒時會與上述環狀凸部接觸受到大的損害而使得毛粒容易產生。 When the height h of the above-mentioned ring-shaped protrusion is less than 20μm, it is difficult to sufficiently prevent the winding of the glass yarn from being slipped, and the wireless head cannot be suppressed. When the height h of the above-mentioned ring-shaped convex portion exceeds 200μm, the glass yarn will unwind from the reel Partial contact is greatly damaged, making hair particles easy to produce.

並且，作為相鄰的該環狀凸部彼此之中心間距離的間隔d1 小於100μm，則環狀凸部彼此的間隔過窄，捲繞後的玻璃紗線不能充分地進入其間隙，不易獲得捲繞偏移抑制效果，而不能抑制無線頭。大於9400μm時，會使得與環狀凸部接觸的玻璃紗線的比例降低，不能獲得充分的捲繞偏移抑制效果，不能抑制無線頭。 並且，相對於上述環狀凸部的高度h之相鄰的該環狀凸部彼此的中心間距離的間隔d1 的比d1 /h小於3.4~75.0，或大於75.0時，不能抑制無線頭的產生。 本發明的繞線筒是以相對於上述環狀凸部的高度h之相鄰的該環狀凸部彼此的中心間距離的間隔d1 的比(d1 /h)在5.0~30.0的範圍為佳。藉著使相對於上述環狀凸部的高度h之相鄰的該環狀凸部彼此的中心間距離的間隔d1 的比(d1 /h)在上述範圍，可更確實地防止無線頭的產生，並且，可更有效地抑制毛粒的產生。 又，本發明的繞線筒中，上述環狀凸部是以剖面呈梯形的上底的長度W1 在180~500μm的範圍，下底的長度W2 在180~800μm的範圍為佳。上述環狀凸部藉著使剖面呈梯形的上底的長度W1 及下底的長度W2 在上述範圍，可進一步有效抑制無線頭的產生。 又，本發明的繞線筒為上述環狀凸部是剖面呈梯形的上底的長度W1 及下底的長度W2 在上述範圍時，以相對於下底的長度W2 之上底的長度W2 的比(W1 /W2 )在0.90~1.00的範圍為佳。藉著使上述環狀凸部的剖面呈梯形之相對於下底的長度W2 的上底的長度W1 的比(W1 /W2 )在上述範圍時，可極有效地抑制無線頭的產生。 又，本發明的繞線筒為上述捲線用圓筒部的上部加工率是以50%以上的範圍為佳。 上述捲線用圓筒部的上部加工率是意味著相對於該捲線用圓筒部的上半部的長度L1 的設有上述環狀凸部的區域(以位在最下部的環狀凸部為起點，以位在最上部的環狀凸部為終點的區域)的長度L2 的比例。 上述捲線用圓筒部的上部加工率只要是50%以上，即使未能滿足：設置於上述捲線用圓筒部的下半部的環狀凸部的其高度h在20~200μm的範圍、相鄰的該環狀凸部彼此的中心間距離的間隔d1 在100~9400μm的範圍、相對於高度h之相鄰的環狀凸部彼此的中心間距離的間隔d1 的比d1 /h在3.4~75的範圍的條件，仍可抑制無線頭的產生。 再者，上述上半部是意味著從繞線筒的上端開始，從繞線筒的上端到繞線筒的全長的50%的地點為止的範圍，上述下半部是意味著從繞線筒的上端到繞線筒的全長的50%的地點開始，到繞線筒的下端為止的範圍。 並且，本發明的繞線筒為上述捲線用圓筒部的上部加工率是以在50~95%的範圍更佳。本發明的繞線筒藉著使上述捲線用圓筒部的上部加工率在上述的範圍，可進一步有效地抑制毛粒的產生。 又，本發明的紗線卷裝是以在具備上述其中任一的構成的繞線筒，捲繞0.3~2.7g/km的範圍的玻璃紗線為特徵。 根據本發明的紗線卷裝，在具備上述其中任一的構成的繞線筒，捲繞上述範圍的玻璃紗線，藉此可更確實地防止無線頭的產生，並且，可更有效抑制毛粒的產生。In addition, if the distance d 1 between the centers of adjacent ring-shaped convex portions is less than 100 μm, the gap between the ring-shaped convex portions is too narrow, and the wound glass yarn cannot enter the gap sufficiently, making it difficult to obtain The winding offset suppression effect can not suppress the wireless head. When it is larger than 9400 μm, the ratio of the glass yarn in contact with the annular convex portion is reduced, and a sufficient winding offset suppression effect cannot be obtained, and the wireless head cannot be suppressed. In addition, when the ratio d 1 /h of the distance d 1 between the centers of adjacent ring-shaped protrusions relative to the height h of the ring-shaped protrusions is less than 3.4 to 75.0, or greater than 75.0, the wireless head cannot be suppressed. The production. The bobbin of the present invention has a ratio (d 1 /h) of the interval d 1 of the distance between the centers of adjacent annular protrusions relative to the height h of the annular protrusion in the range of 5.0 to 30.0 Better. By setting the ratio (d 1 /h) of the interval d 1 of the distance between the centers of adjacent annular protrusions relative to the height h of the annular protrusion within the above range, wireless heads can be prevented more reliably The production of hair particles can be more effectively inhibited. Furthermore, in the bobbin of the present invention, it is preferable that the length W 1 of the upper base having a trapezoidal cross-section is in the range of 180 to 500 μm, and the length W 2 of the lower base is preferably in the range of 180 to 800 μm. By making the length W 1 of the upper base and the length W 2 of the lower base of the trapezoidal cross-section into the above-mentioned range of the annular convex portion, the generation of the wireless head can be further effectively suppressed. Furthermore, in the bobbin of the present invention, when the length W 1 of the upper base and the length W 2 of the lower base having a trapezoidal cross-section of the above-mentioned ring-shaped convex portion are in the above range, the upper and lower bases are relative to the length W 2 of the lower base. The ratio of the length W 2 (W 1 /W 2 ) is preferably in the range of 0.90 to 1.00. By making the cross section of the annular projecting portion of the trapezoidal phase ratio (W 1 / W 2) to the lower end of the length of the upper base length W 1 W 2 in the above range, can be very effectively suppressed radio head produce. In addition, in the bobbin of the present invention, the upper processing rate of the cylindrical portion for winding is preferably in the range of 50% or more. The processing rate of the upper part of the cylindrical part for winding means the area where the above-mentioned annular convex part is provided with respect to the length L 1 of the upper half of the cylindrical part for winding (the annular convex part located at the bottom As the starting point, the ratio of the length L 2 to the region where the ring-shaped convex portion located at the uppermost end is the end point). As long as the upper processing rate of the cylindrical portion for winding is 50% or more, even if it is not satisfied: the height h of the annular convex portion provided on the lower half of the cylindrical portion for winding is in the range of 20 to 200 μm. The distance d 1 between the centers of adjacent annular convex portions is in the range of 100 to 9400 μm, and the ratio d 1 /h of the interval d 1 of the distance between the centers of adjacent annular convex portions with respect to the height h In the range of 3.4 to 75, the generation of wireless heads can still be suppressed. In addition, the above-mentioned upper half means the range starting from the upper end of the bobbin, from the upper end of the bobbin to the point of 50% of the total length of the bobbin, and the lower half means the range from the upper end of the bobbin The upper end of the spool starts at 50% of the full length of the spool and reaches the lower end of the spool. In addition, it is more preferable that the bobbin of the present invention is the upper part of the cylindrical portion for winding, and the processing rate is in the range of 50-95%. In the bobbin of the present invention, by setting the upper processing rate of the cylindrical portion for winding in the above range, the generation of lint can be further effectively suppressed. In addition, the yarn package of the present invention is characterized by winding a glass yarn in the range of 0.3 to 2.7 g/km on a bobbin having any of the above-mentioned configurations.

In addition, in this embodiment, as shown in Figure 2, the height of the annular convex portion 5 with respect to the peripheral surface 3a of the cylindrical portion 3 is set to h, and the distance between the centers of adjacent annular convex portions 5, 5 is set. The interval between the annular protrusions 5, 5 is d 1 , the distance between the lower ends of the adjacent annular protrusions 5, 5 is d 2 , the interval between the annular protrusions 5, 5 is d 2 , the annular protrusion is set The length of the upper bottom of the trapezoidal section of 5 is W 1 , and the length of the lower bottom is W 2 . In addition, the cross-section of the ring-shaped convex portion 5 is trapezoidal, including the corners of the upper base being a rounded substantially trapezoid, or the upper base and the lower base having the same length as a rectangle or a square. In the bobbin 1 of this embodiment, by setting the height h of the ring-shaped convex portion 5 in the range of 20 to 200 μm, the distance d 1 between the centers of the adjacent ring-shaped convex portions 5 and 5 is at In the range of 100 to 9400 μm, the ratio d 1 /h of the interval d 1 of the distance between the centers of adjacent annular convex portions 5 and 5 relative to the height h of the annular convex portion 5 is in the range of 3.4 to 75.0, even if When winding extremely fine glass yarns below 2.7g/km, the generation of wireless heads can still be suppressed. The height h of the annular convex portion 5 is preferably in the range of 30 to 180 μm, preferably in the range of 35 to 160 μm, and more preferably in the range of 40 to 90 μm. In addition, the distance d 1 between the centers of adjacent annular convex portions 5 and 5 is preferably in the range of 150 to 7000 μm, preferably in the range of 200 to 3500 μm, more preferably in the range of 200 to 3500 μm, and further It is ideally in the range of 300 to 2000 μm, and most preferably in the range of 400 to 800 μm. In addition, the distance d 2 between the centers of adjacent annular convex portions 5 and 5 is, for example, in the range of 7000 μm or less, preferably in the range of 150 to 3300 μm, more preferably in the range of 180 to 1500 μm, and more preferably in the range The range of 200~600μm. In addition, the ratio d 1 /h of the distance d 1 between the centers of adjacent annular convex portions 5 and 5 with respect to the height h of the annular convex portion 5 is preferably in the range of 3.5 to 63.4, and more preferably It is the range of 4.0-50.0, More preferably, it is the range of 5.0-30.0 micrometers. In the bobbin 1 of this embodiment, the ratio d 1 /h of the distance d 1 between the centers of adjacent annular convex portions 5 and 5 relative to the height h of the annular convex portion 5 is 5.0 to In the range of 30.0, it is possible to more reliably prevent the generation of wireless heads when the number of wireless heads is less than 30%, and to suppress the generation of hair particles when the number of hairs is less than 4. In addition, the rate of generation of wireless heads is that after the yarn package is left standing at 5°C for 12 hours, a vibration testing machine with a constant temperature bath is used to give 500 vibrations at 25G under a 5°C ambient environment. When unwinding the glass yarn after winding from the end of the winding to the starting end, the total count of the yarn package used for the evaluation of the endless end can be divided by the yarn package count after the glass yarn is cut. Got. In addition, the number of hair particles produced is based on the fact that the yarn package is left to stand at 5°C for 12 hours, and then a vibration tester with a constant temperature bath is used to give 500 vibrations at 25G under a 5°C ambient environment. When unwinding the glass yarn after winding from the end of the winding to the start end, when unwinding the glass yarn after winding from the end of the winding to a position 5000m before the start end, wool can be used The particle measurement device counts the number of bristles from a position 5000 m before the start end to the start end as the total number of bristles per 333 m of the glass yarn. The bobbin 1 in the present embodiment, with respect to each other, the distance between centers of adjacent projecting height h of the annular portion of the annular projections 5 d d 1 ratio of 5,5 1 / h in particular in ~ 7.0 The range of 25.0 is preferable, and the range of 8.0 to 15.0 is most preferable. In the bobbin 1, the length W 1 of the upper bottom of the trapezoidal cross-section of the annular convex portion 5 may be in the range of 50 to 1900 μm, for example, but since the generation rate of the wireless head is less than 20%, its generation can be more reliably suppressed. Therefore, the range of 180~500μm is preferred, and the range of 200~450μm is more preferred, and the most preferred is the range of 210~320μm. In addition, when the cross-sectional display shape of the annular convex portion 5 is approximately trapezoidal at the corner of the upper base, the length W 1 of the upper base can be obtained as follows. First, a straight line parallel to a straight line b connecting two points (B 1 and B 2 in Fig. 3) of the starting point of the annular convex portion 5 is drawn at half the height h of the annular convex portion 5. Next, at two points (M 1 and M 2 in Fig. 3) where this straight line intersects with the annular convex portion 5, the wires are drawn out (t 1 , t 2 in Fig. 3). Then, through the apex of the annular convex portion 5, draw a straight line s parallel to the straight line b, and then set the intersection point of the straight line s and the connection t 1 as A 1 , and set the intersection point of the straight line s and the connection t 2 as A 2 , and set The distance between A 1 and A 2 is the length of the upper base W 1 . On the other hand, the length W 2 of the bottom bottom of the trapezoidal cross-section of the ring-shaped convex portion 5 may be in the range of 50 to 3000 μm, for example, but since the generation rate of the wireless head is less than 20%, its generation can be more reliably suppressed. The range of 180 to 800 μm is preferable, and the range of 200 to 700 μm is more preferable, the range of 210 to 350 μm is more preferable, and the range of 220 to 290 μm is most preferable. Then, the bobbin 1, with respect to the cross section of the annular projecting portion 5 at the bottom of the trapezoidal top of the bottom longitudinal length W 2 W 1 W ratio of the 1 / W 2 may be, for example, although in the range of 0.05 to 1.00 , But because the generation rate of wireless heads is less than 20%, it can be more effectively suppressed, so the range of 0.30~1.00μm is better, and because the generation rate of wireless heads is less than 10%, its generation can be suppressed very effectively, so The range of 0.90 to 1.00 μm is more preferable, and the range of 0.90 to 0.98 is more preferable. In addition, in the bobbin 1, the area where the annular convex portion 5 is provided in the upper half relative to the length L 1 of the upper half of the cylindrical portion 3 (the upper half is the lowermost annular convex portion 5 is the starting point, in the upper half of the area with the ring-shaped convex portion 5 located at the top as the end point) the ratio of the length L 2 L 2 /L 1 indicates that the upper part of the cylindrical part 3 has a processing rate of more than 50% The range is better. When the upper processing rate of the cylindrical portion 3 is 50% or more, even if it is not satisfied: the annular convex portion 5 provided in the lower half of the cylindrical portion 3 has a height h in the range of 20 to 200 μm, and the adjacent The distance d 1 of the distance between the centers of the annular convex portions 5 and 5 is in the range of 100-9400 μm, and the ratio d of the interval d 1 of the distance between the centers of the adjacent annular convex portions 5 and 5 of the height h If 1 /h is in the range of 3.4 to 75, the generation of wireless heads can still be suppressed. In the bobbin 1, the processing rate of the upper part of the cylindrical portion 3 is preferably in the range of 50-95%, and the number of hair particles can be less than 3.5, which can more effectively suppress the production. In addition, the above-mentioned upper processing rate of the cylindrical portion 3 is more preferably in the range of 55 to 90%, and more preferably in the range of 60 to 85%, especially in the range of 63 to 80%, and most preferably 65 ~78%. In addition, in the bobbin 1, the area where the annular convex portion 5 is provided in the lower half relative to the length L 3 of the lower half of the cylindrical portion 3 (the lower half is the annular convex portion 5 located at the lowermost portion As the starting point, in the lower half of the region with the uppermost annular convex portion 5 as the end point) the ratio of the length L 4 L 4 /L 3 represents the range where the processing rate of the lower part of the cylindrical portion 3 is above 50% Preferably, it is more preferably in the range of more than 70%, more preferably in the range of more than 80%, especially in the range of 90 to 99%. And, across the entire bobbin 1, the height h of the annular convex portion 5, and the distance d 1 between the centers of the adjacent annular convex portions 5, 5 relative to the height h of the annular convex portion 5 The ratio d 1 /h may be the same, and in the bobbin 1, there may be multiple regions where the above h and the above d 1 /h are different. In addition, the yarn package of the present embodiment winds a glass yarn in the range of 0.3 to 2.7 g/km on the bobbin 1 shown in Fig. 1, so that the generation of a wireless head can be prevented more reliably, and, Can more effectively inhibit the production of hair particles. In addition, the yarn package of this embodiment is preferably to wind the glass yarn in the range of 0.4 to 2.0 g/km on the bobbin 1 shown in Figure 1, and to wind the glass yarn in the range of 0.5 to 1.7 g/km A range of glass yarn is better.
