Description

高強力耐切割複合紗線及其製法High-strength cutting-resistant composite yarn and preparation method thereof

本發明是有關於一種紗線及其製法，特別是指一種用於製成包包、衣著或手套等各項紡織品的高強力耐切割複合紗線及其製法。 The invention relates to a yarn and a manufacturing method thereof, in particular to a high-strength cutting-resistant composite yarn used for making various textiles such as bags, clothing or gloves and a manufacturing method thereof.

已知用於製作成包包、衣著或各項紡織品的織布，是利用紗線編織而成，為了提升紗線抗拉扯、耐切割的性能，參閱圖1，目前有一種複合紗線，其結構包含兩條位於內部的芯線91，以及一條纏繞包覆於該等芯線91外的包覆線92。該等芯線91是以相互平行的方式設置，外部再以該包覆線92螺旋盤繞包覆，進而構成該複合紗線。實務上發現，因複合紗線製作時，會受到揉、捏，或拉伸等過程，當該複合紗線受到外力拉扯時，由於該等芯線91僅是並排設置而沒有特殊的結合關係，因此每一芯線91便單獨抵抗外力而有容易斷裂之情況，一旦芯線91斷裂，就必須中斷紗線生產過程，導致生產效率差。而且該複合紗線後續製成紡織物後，同樣會因芯線91易受拉扯而斷裂，影響此紗線結構的實用性，紡織物也較容易出現過長的毛羽，進而影響紡織物的美觀性，因此已知的複合紗線需要改良。 It is known that the woven fabric used for making bags, clothing or various textiles is woven from yarn. In order to improve the resistance of the yarn to pulling and cutting, refer to FIG. 1, there is currently a composite yarn, which The structure includes two core wires 91 located inside and a covered wire 92 wrapped around the core wires 91. The core wires 91 are arranged parallel to each other, and the outside is spirally wrapped with the covered wire 92 to form the composite yarn. It has been found in practice that the composite yarn is subjected to kneading, kneading, or stretching processes when it is made. When the composite yarn is pulled by an external force, the core wires 91 are only arranged side by side without a special bonding relationship, so Each core wire 91 resists external force alone and may be easily broken. Once the core wire 91 breaks, the yarn production process must be interrupted, resulting in poor production efficiency. Moreover, after the composite yarn is subsequently made into a textile, it will also be broken due to the core 91 being easily pulled, which affects the practicality of this yarn structure, and the textile is also easier to produce The excessively long hairiness affects the aesthetics of the textile, so the known composite yarn needs improvement.

The core unit includes a first core body, and a second core body twisted with the first core body and helically wound with each other, the first core body is glass fiber, and the material of the second core body is different from the first The material of a core body, and the tensile strength of the second core body is more than three times the tensile strength of the first core body.

參閱圖2、3，本發明高強力耐切割複合紗線的一實施例，包含一個芯線單元1，以及一個包覆單元2。 2 and 3, an embodiment of the high-strength cutting-resistant composite yarn of the present invention includes a core unit 1 and a covering unit 2.

該芯線單元1包括一條第一芯線體11，以及一條與該第一芯線體11扭合而彼此螺旋纏繞並緊密貼合的第二芯線體12。該第一芯線體11為玻璃纖維，具有高硬度、輕量之優點，其高硬度特性具有耐切割及耐磨的性能。該第二芯線體12的材質不同於該第一芯線體11的材質，本實施例的第二芯線體12為超高分子量聚乙烯纖維(簡稱UHMWPE)、對位芳香族聚醯胺，或液晶纖維等高抗拉強力的纖維。該第二芯線體12的材質皆具有耐切割、耐磨、高強韌，以及高抗張力特性，可抵受高強度的機械應力並有良好的抗拉強度。在本實施例中，該第二芯線體12的抗拉強度(Tensile Strength)為該第一芯線體11的抗拉強度的三倍以上，其中，UHMWPE的抗拉強度約為35g/d、對位芳香族聚醯胺的抗拉強度約為25g/d、液晶纖維的抗拉強度約為20g/d，而第一芯線體11的玻璃纖維抗拉強度為5~6g/d，所以該第二芯線體12材質能完全保護該第一芯線體11不因外力拉扯而有所破壞。該第一芯線體11與該第二芯線體12可以透過合撚製程而扭合在一起，該芯線單元1的撚度為5~350TPM，其撚度須依不同的紗線之丹尼(Denier)而設定。撚度的定義為單位長度上所受加撚的次數，而TPM(Twist Per Meter)為公制單位，是指每公尺所受加撚的次數。 The core unit 1 includes a first core body 11 and a second core body 12 twisted with the first core body 11 and spirally wound and closely adhered to each other. The first core body 11 is made of glass fiber, which has the advantages of high hardness and light weight. It has cutting and abrasion resistance. The material of the second core body 12 is different from the material of the first core body 11. The second core body 12 of this embodiment is ultra-high molecular weight polyethylene fiber (abbreviated as UHMWPE), para-aromatic polyamide, or liquid crystal Fibers with high tensile strength such as fibers. The materials of the second core body 12 are cut-resistant, wear-resistant, high-strength, and high-tensile, and can withstand high-strength mechanical stress and have good tensile strength. In this embodiment, the tensile strength of the second core body 12 is more than three times the tensile strength of the first core body 11, wherein the tensile strength of UHMWPE is about 35g/d. The tensile strength of the aromatic polyamide is about 25g/d, the tensile strength of the liquid crystal fiber is about 20g/d, and the tensile strength of the glass fiber of the first core body 11 is 5 to 6g/d, so the first The material of the second core body 12 can completely protect the first core body 11 from being damaged by external force. The first core body 11 and the second core body 12 can be twisted together through a twisting process. The twist of the core unit 1 is 5 to 350 TPM, and the twist must be determined according to the different yarn denier (Denier). set up. Twist is defined as the number of twists per unit length, and TPM (Twist Per Meter) is a metric unit, which refers to the number of twists per meter.

該包覆單元2與該芯線單元1扭合而螺旋纏繞該芯線單元1，並包括兩條包覆線體21。該等包覆線體21為尼龍纖維、聚酯纖維、棉纖維，或嫘縈纖維。該等包覆線體21以S撚向加上Z撚向螺旋纏繞方式，但於實施時不限於此，不須限定包覆線體21的纏繞方向。所述包覆線體21可如同本實施例設置兩條，但也可以僅設置一條，因此本發明的包覆線體21數量為至少一個，其撚向不局限於S撚或Z撚。 The covering unit 2 is twisted with the core wire unit 1 to spirally wind the core wire unit 1 and includes two covered wire bodies 21. The covered threads 21 are nylon fiber, polyester fiber, cotton fiber, or rayon fiber. The covered wires 21 are spirally wound in the S twist direction and the Z twist direction, but the implementation is not limited thereto, and the winding direction of the covered wires 21 need not be limited. The covered wire body 21 may be provided with two pieces as in this embodiment, but it may also be provided with only one The number of covered wires 21 of the present invention is at least one, and the twisting direction is not limited to S twisting or Z twisting.

參閱圖2~4，本發明高強力耐切割複合紗線的製法，包含以下步驟： Referring to FIGS. 2 to 4, the method for manufacturing the high-strength cutting-resistant composite yarn of the present invention includes the following steps:

步驟31：準備不同材質的該第一芯線體11與該第二芯線體12，將該第一芯線體11與該第二芯線體12相鄰配置。 Step 31: Prepare the first core body 11 and the second core body 12 of different materials, and arrange the first core body 11 and the second core body 12 adjacent to each other.

步驟32：將該第一芯線體11與該第二芯線體12相互扭合而使其彼此螺旋纏繞，進而形成該芯線單元1。本步驟是將配置完成的該第一芯線體11與第二芯線體12的一端拉出，並通過一對低轉速的滾輪(圖未示)，透過滾輪將該第一芯線體11與第二芯線體12合撚而扭合並緊密纏繞在一起，所述滾輪的轉速適當，使該芯線單元1的撚度為5~350TPM，透過適當的撚度範圍，可避免該第一芯線體11的玻璃纖維在與該第二芯線體12合撚時斷裂。 Step 32: Twist the first core wire body 11 and the second core wire body 12 to spirally wind each other, thereby forming the core wire unit 1. In this step, one end of the first core body 11 and the second core body 12 that have been configured is pulled out, and through a pair of low-speed rollers (not shown), the first core body 11 and the second The core body 12 is twisted and twisted and tightly wound together. The rotation speed of the roller is appropriate, so that the twist of the core unit 1 is 5~350TPM. Through the appropriate twist range, the glass fiber of the first core body 11 can be It breaks when twisted with the second core body 12.

步驟33：將該包覆單元2與該芯線單元1包覆纏繞，使該包覆單元2螺旋纏繞該芯線單元1。本步驟是將該包覆單元2的該等包覆線體21通過一對高轉速滾輪(圖未示)而至該芯線單元1外部，使該等包覆線體21螺旋纏繞包覆該芯線單元1，其中兩個高轉速滾輪是用於分別完成S撚向與Z撚向的螺旋纏繞。於實施時，也可以僅使用一條包覆線體21來螺旋纏繞該芯線單元1，其撚向不局限於S撚或Z撚。 Step 33: Wrap the covering unit 2 with the core wire unit 1 so that the covering unit 2 spirally winds the core wire unit 1. In this step, the covered wires 21 of the covered unit 2 are passed to the outside of the core wire unit 1 through a pair of high-speed rollers (not shown), so that the covered wires 21 are spirally wound to cover the core wire Unit 1, two high-speed rollers are used to complete the spiral winding of S twist direction and Z twist direction respectively. During implementation, the core wire unit 1 may be spirally wound using only one covered wire body 21, and its twisting direction is not limited to S twisting or Z twisting.

其中，在步驟32中，只需要以較低轉速來進行該第一芯線體11與第二芯線體12的合撚，就能藉由第一芯線體11與第二芯線體12的扭合結構來提升該芯線單元1以及紗線整體強度。而步驟33是為了使包覆線體21的包覆纏繞密度較高，因此相對於步驟32採用轉速較高的滾輪。此外，由於步驟32、33中，將複數線體合撚而使其彼此纏繞的製作過程與細節，非本發明的改良重點，故不再說明。 Wherein, in step 32, only the twisting of the first core body 11 and the second core body 12 can be performed by twisting the first core body 11 and the second core body 12 at a relatively low speed To enhance the strength of the core unit 1 and the overall yarn. Step 33 is to make the wrapped winding density of the covered wire body 21 higher, so a roller with a higher rotational speed is used compared to step 32. In addition, since the manufacturing process and details of twisting a plurality of wires in Steps 32 and 33 to twist them are not the focus of the improvement of the present invention, they will not be described again.

本發明藉由該第一芯線體11與該第二芯線體12扭合纏繞，可提升該芯線單元1與紗線整體的強度與抗拉扯性能，當紗線受到揉捏拉扯時，該第一芯線體11與該第二芯線體12之間的螺旋纏繞結構，可形成相互扶撐效果以緩解拉扯力道，進而大幅減少第一芯線體11之玻璃纖維斷裂的情況，如此就可減少複合紗線製作過程中，生產中斷的情形。因此本發明可有效提升芯線單元1與紗線整體生產時的效率及品質，並減少紡織物出現毛羽過長的問題。該芯線單元1的第一芯線體11之玻璃纖維材質，搭配絞合在一起的該第二芯線體12，能讓本發明複合紗線的結構所製成的成品具有絕佳耐切割的效果。 In the present invention, the first core body 11 and the second core body 12 are twisted and twisted to improve the strength and anti-pull performance of the core unit 1 and the entire yarn. When the yarn is kneaded and pulled, the first The spiral winding structure between the core body 11 and the second core body 12 can form a mutual support effect to ease the pulling force, thereby greatly reducing the breakage of the glass fiber of the first core body 11, so that the composite yarn can be reduced In the production process, production is interrupted. Therefore, the present invention can effectively improve the efficiency and quality of the entire production of the core unit 1 and the yarn, and reduce the problem of excessive hairiness of the textile. The glass fiber material of the first core body 11 of the core unit 1 and the second core body 12 twisted together can make the finished product made of the composite yarn structure of the present invention have excellent cutting resistance.

將本發明的複合紗線進行ANSI耐切割測試，美規標準規範ANSI分成1~9級，等級越高表示耐切割效果越佳。本發明測試結果為第4級以上，而將先前技術所述之已知複合紗線進行測試，測試結果為第3級，可見得本發明的第一芯線體11與第二芯線體12絞合的結構，確實能有效提升抗拉強度與耐切割效果，減少芯線單元1斷裂的問題。 The composite yarn of the present invention is subjected to the ANSI cut resistance test. The American standard ANSI is divided into 1 to 9 grades. The higher the grade, the better the cut resistance. The test result of the present invention is above level 4, and the known composite yarn described in the prior art is tested, The test result is level 3, and it can be seen that the structure in which the first core body 11 and the second core body 12 are twisted in the present invention can effectively improve the tensile strength and the cutting resistance, and reduce the problem of the core unit 1 breaking.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention.
