技术领域 FIELD

[0001] 本发明涉及耐切割性合股线(ply-twisted yarn)和由该线制成的用于保护性服装、特别是用于消防队员的消防外衣(turnout gear)服装的织物,但是这种织物和服装也用于操作者可能暴露于磨蚀和需要火和火焰的机械苛刻环境的工业应用。 [0001] relates to cut resistance twine (ply-twisted yarn), and by the line made for protective clothing, especially fire coat (turnout gear) for firefighter garment fabric of the present invention, but this fabrics and clothing for the operator may also be exposed to abrasion and industrial applications require mechanical fire and flames harsh environments. 这些服装,包括衣服、外衣、夹克和/或裤可以提供抵抗火、火焰和热的保护作用。 These garments, including clothes, outerwear, jackets and / or pants can provide fire resistance, flame and heat protection.

背景技术 BACKGROUND

[0002] 在美国,大多数常用于消防队员的外衣包括三层,各自具有不同的功能。 [0002] In the United States, most commonly used in firefighter's coat include three layers, each with different functions. 外壳织物通常由耐火焰性芳族聚酰胺纤维例如聚间、苯二甲酰间苯二胺(MPD-I)或聚对苯二甲酰对苯二胺poly (p-phenyleneter印hthal-amide) (PPD-T)或这些纤维的共混物与耐火焰性纤维例如聚苯并咪唑(PBI)制成。 Shell fabric often e.g. poly-m, m-phenylene isophthalamide (MPD-I) or poly-resistant flame resistant aromatic polyamide fiber terephthalamide phenylenediamine poly (p-phenyleneter printed hthal-amide) (PPD-T) or blends of these fibers with flame resistant fibers such as polybenzimidazole (PBI) is made. 与外壳织物邻近的是水分阻隔物,常用的水分阻隔物包括Cross tech® PTFE膜在织造MPD-I/PPD-T基材上的层压材料,或者氯丁橡胶在纤维织造聚酯/棉基材上的层压材料。 And the shell fabric is adjacent the moisture barrier, the moisture barrier comprises a common Cross tech® PTFE film on a woven MPD-I / PPD-T substrate, laminate, or neoprene fiber woven polyester / cotton substrate laminate material on. 与水分阻隔物邻近的是隔热衬里,它通常包含耐热性纤维的毛层。 And moisture barrier is adjacent insulating lining, which typically contains heat resistant fiber batt.

[0003] 外壳用作初始的防火焰,而隔热衬里和水分阻隔物保护不受热应力的影响。 [0003] The shell used as the initial anti-flame, and heat insulation lining and moisture barrier protection against thermal stress. [0004] 因为外壳提供主要的防护作用,所以希望外壳应该是耐久性的,能经受磨蚀和抵抗在苛刻环境中的磨损或切割。 [0004] Since the housing to provide the main protective effect, so I hope the housing should be durable and able to withstand the abrasion resistance in harsh environments and wear or cut. 本发明提供优选具有耐火焰性且具有良好的磨损、切割和摩擦特性的织物。 Preferably the present invention provides a flame resistant and has good wear resistance, cutting and frictional properties of the fabric.

[0005] 在现有技术中描述了许多织物,它们使用裸钢丝和帘子线,主要作为防护的织物。 [0005] described in the prior art, a lot of fabric, they use bare wires and cords, primarily as a protective fabric. 例如,W09727769(Bourgois等)公开了保护性织物,包含多个合股在一起的钢帘子线。 For example, W09727769 (Bourgois et al) discloses a protective fabric comprising a plurality of steel cords twisted together. W0 200186046 (Vanassche等)公开了包含钢元件的织物,钢元件用于提供耐切割性或向保护性织物提供增强作用。 W0 200186046 (Vanassche et al) discloses a fabric comprising steel elements, steel elements used to provide cut resistance or to provide a protective fabric reinforcement. 钢元件是单个钢丝、没有合股的钢丝束或者合股的钢丝纤维的帘子线。 Steel components are single wire, wire bundles no partnership or joint-stock steel fiber cords.

[0008] 虽然无机长丝例如钢可以为织物提供有用的耐切割性,但是将这些无机长丝引入织物中不是一个简单的问题,特别是当这些无机长丝与其它连续有机长丝线组合时。 [0008] While inorganic filaments such as steel can provide useful cut resistance of the fabric, but the introduction of these inorganic filaments in the fabric is not a simple matter, especially when these inorganic filaments with other continuous organic filament line combinations. 大多数含有连续的有机长丝的复丝具有初始的合股以保持的结合。 Most multifilament yarns containing continuous organic filaments having plied in order to maintain the initial binding. 如果无机长丝简单地合股到以前的合股线中,最终的线会太活跃,即它具有过多的合股并倾向于自身合股和缠绕,在编织期间发生阻碍,阻止了高质量织物的生产。 If an inorganic filament is simply twisted into strands before, the final line will be too active, i.e., it has too much self-plied and twisted and tends to wound, obstruction occurs during weaving, preventing high quality fabrics production. 此外,如果无机长丝与复丝在没有合股或者在合股很少的情况下组合,所得的线将没有足以进行纺织的结合力。 Further, if the inorganic filament and plied multifilament or in combination at no plied rare cases, to the wire will not be sufficient for binding textiles. 所以,需要一种提供含有连续长丝的复丝和连续无机长丝且具有低活跃性和容易纺织成织物的合股线。 Therefore, a need exists to provide a multifilament yarn comprising continuous filaments and continuous inorganic filaments and has a low activity and readily woven into the fabric strands. 发明内容 SUMMARY

[0020] 本发明涉及耐切割性合股线,生产合股线的方法,含有合股线作为耐切割性组分的织物,以及生产含有合股线作为耐切割性组分的织物的方法。 [0020] The present invention relates to cut resistance twine, twine production method, comprising twine as resistant fabric cutting resistance component, and the production line as a resistant fabric containing ply cutting resistance component method.

[0021 ] 合股线或堆叠线是通过将两种不同的线扭巻在一起形成的线,通常在加捻机上进行。 [0021] twine or wire is formed by stacking two different lines Volume wire twisted together to form, usually on the twisting machine. 合股线是本领域公知的,是通过简单的方式彼此扭巻在一起,在观察时显然合股线是由不同的线组成。 Strands are known in the art, and is a simple way Volume twisted with each other, apparently twine is composed by different lines at the time of observation. 合股线通常更具柔性,所以与通过将一种线彼此完全缠绕或与另一种线用在另一种线周围的一种线包裹形成的一种线相比,合股线更有利地用于服装。 Twine usually more flexible, so with each other by a line completely wound or with another line in a line with a wire wrapped around another line formed compared more favorably for twine clothing. 这些缠绕的线具有皮/芯结构,不是合股线。 These lines have wrapped sheath / core structure, not the twine.

[0022] 耐切割性可以通过向由连续有机长丝形成的复丝中加入仅仅一些无机长丝来改进。 [0022] The cut resistance by the multifilament continuous organic filaments formed by adding only a few inorganic filaments to improve. 实际上,加入仅仅l个金属长丝就显著提高了由这些线制成的织物的耐切割性。 In fact, only l was added to a metal filament significantly improves the fabric made from these lines cut resistance. 但是希望向有机复丝束中尽可能多地加入这种线以提供线的结合力和使得无机增强的线能在编织设备中加工,尽管其中不存在无机或金属长丝。 However, in the hope that the organic multifilament bundle as much as possible is added to this line and the supply line of the bonding force such that an inorganic reinforcing wire can be processed in a weaving device, although the absence of an inorganic or metal filaments.

[0023] 通常,结合力是通过扭巻向连续长丝线提供的。 [0023] Typically, the binding force is provided by Volume twisted wire to continuous filaments. 但是,具有仅仅一些长丝的无机长丝线与较大的具有许多长丝的复丝的组合存在许多独特的问题。 However, with the mere existence of a number of unique problems some filaments of inorganic filaments having a larger line with a combination of a number of filaments of the multifilament. 较大的复丝已经具有一定水平的扭巻以提供其结合力。 Larger multifilament yarn already has a level of twist to provide Volume its binding force. 当小的无机长丝线与较大的复丝组合时,额外的扭巻被加入复丝中。 When the small and large inorganic filaments multifilament line combinations Volume additional twist is added multifilament. 这导致在最终线中不可接受水平的扭巻,据说这种线太活跃以致不能有效地纺织成织物。 This resulted in an unacceptable level in the final line of twisted Volume, said that this line too active that can not be effectively woven into the fabric. 也就是说,这些线具有过多的扭巻,以致如果要将线的任一端用最小的张力保持在一起,该线将倾向于自身巻绕而形成结。 That is, these lines have excessive twist Volume, such that if either end of the line to be held together with a minimum of tension, the wire will tend Volume around itself to form junctions. 这些相同的结将形成和阻碍加工设备。 These same results will hinder the formation and processing equipment. [0024] 本发明的合股线含有连续有机长丝的第一种复丝,具有在第一方向上0. 5-10转/ 英寸的扭巻。 [0024] The first multifilament twine the present invention comprises a continuous organic filaments, with 5-10 in the first direction 0.1 turns / inch Volume twist. 合股线还包含含有l-5个连续无机长丝的第二种线。 Twine further comprising a second wire comprising l-5 consecutive inorganic filaments. 第一和第二种线是以2-15转/英寸在第二方向合股在一起,所述第二方向与第一种线的巻绕方向相反,得到有效合股水平为+/_5转/英寸的合股线。 The first and second lines is 2-15 turns / inch plied together in a second direction, the second direction is a direction about the first line Volume contrary, effective plied level of + / _ 5 rev / inch The twine. "有效合股水平"表示每英寸的转数的数学总和,其中复丝巻绕方向是负的,合股方向是正的。 "Effective partnership level" means the sum of the number of math per inch turn around the direction in which the multifilament Volume is negative, the direction is positive partnership. 例如,如果复丝在一个方向上的合股水平是5转/英寸,合股线在相反方向上的合股水平是7转/英寸,则有效合股水平为-5+7 = 2转/英寸。 For example, if the level of multifilament twisted in one direction is 5 turns / inch, twisted strands in the opposite direction level is 7 turns / inch, the effective ply level is -5 + 7 = 2 turns / inch. 如果复丝的合股水平是4转/英寸,合股线在相反方向上的合股水平是2转/英寸,则有效合股水平为-4+2 = -2转/英寸。 If plied multifilament level is 4 turns / inch, twisted strands in the opposite direction level is 2 turns / inch, the effective ply level is -4 + 2 = -2 turns / inch.

[0025] 希望有效合股水平-2至2之间,优选有效合股水平是正的。 [0025] Hope effective ply-level between -2 to 2, preferably the effective joint stock level is positive. 认为正的有效合股水平能提供更大的结合力和较小无机线与较大复丝之间的混合,这是由于复丝连续长丝线在合股期间的部分解缠。 Is believed to provide an effective level of ply adhesion and greater mixing small inorganic line between the larger multifilament yarn, which is due to the multifilament continuous filament plied thread in the partial solution during winding.
