Description  translated from Chinese
用于耐切割性织物的合股线 Twine for cut resistance of the fabric

发明领域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摩蚀和需要火和火焰的机械苛刻环境的工业应用。 Field of the Invention The present invention relates to a cutting resistance twine (ply-twisted yarn) and from this line of clothing made of fabric for protective clothing, particularly for firefighters firefighting coat (turnout gear), but this fabric and clothing are also for the operator to be exposed to corrosion and friction 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, coat, jacket and / or pants can provide fire resistance, flame and heat protection.

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。 In the United States, most commonly used in firefighter coat comprises 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-phenyleneterephthal-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 is usually made of flame-resistant aramid fibers such as poly-m, m-phenylene isophthalamide (MPD-I) or polyethylene terephthalate phenyleneterephthalamide poly (p-phenyleneterephthal-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Crosstech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。 The housing adjacent the fabric is the moisture barrier, the moisture barrier comprises a conventional film on CrosstechPTFE woven MPD-I / PPD-T substrate laminates, neoprene or woven polyester fiber / cotton substrate in laminated material. 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 adjacent insulated lining, which typically contains heat-resistant fiber batt.

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。 Shell used as the initial anti-flame and thermal liner and moisture barrier protection against thermal stress.

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,能经受摩蚀和抵抗在苛刻环境中的磨损或切割。 Because the shell to provide a major protective effect, so I hope the housing should be durable to withstand friction and corrosion resistance in harsh environments abrasion or cutting. 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。 The present invention provides a preferred flame resistant and has good abrasion resistance, cut and friction characteristics of the fabric.

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。 Describes a number of fabric in the prior art, they use bare wires and cords, primarily as a protective fabrics. 例如,WO 9727769(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, WO 9727769 (Bourgois et al) discloses a protective fabric comprising a plurality of twisted steel cords together. WO 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。 WO 200186046 (Vanassche et al) discloses a fabric comprising steel elements, steel elements used to provide cut resistance or reinforcement of protective fabric provided. 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 element is a single wire, wire bundles no partnership or joint stock steel fiber cords.

US4,470,251(Bettcher)公开了通过将许多合成纤维线例如尼龙和芳族聚酰胺缠绕在不锈钢丝股芯的周围制成的耐切割性线,和由该缠绕线制成的安全服装。 US4,470,251 (Bettcher) disclosed by a number of synthetic fiber such as nylon and aromatic polyamide wound around made of stainless steel wire strand core cut resistance line, and safety clothing line made from this wound.

US5,119,512(Dunbar等)公开了由耐切割性线制成的保护性织物,该耐切割性线包含两种不相似的非金属纤维,其中至少一种是柔性的和本质上是耐切割的,另一种具有根据硬度标准的3个Mohs之上的硬度水平。 US5,119,512 (Dunbar et al) discloses cut resistance line formed by the protective fabric, the cut resistance line comprising two dissimilar non-metallic fibers, wherein at least one is flexible and inherently cut resistant the other has a hardness according to above standard 3 Mohs hardness levels.

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。 Although inorganic filaments such as steel can provide useful cut resistance of the fabric, but the introduction of these inorganic filament fabric is not a simple problem, especially when these inorganic filaments and 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 containing continuous organic filaments having an initial partnership in order to maintain the union. 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 the inorganic filaments simply plied to the previous twine, the final line will be too active, that it has too many partnership and tend to their own partnership and winding, obstacle occurs during weaving, preventing the production of high-quality fabrics. 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。 In addition, if the inorganic filaments and multifilament or plied in the absence of a combination of a few cases in the partnership, the resulting line will not be sufficient for binding textile. 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 comprising continuous filaments and continuous inorganic filaments and has a low activity and ease of strands woven into fabrics.

发明的详细描述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。 Detailed Description of the Invention The present invention relates to cut resistance twine, twine production method, the fabric comprising strands cut resistance component as well as a method for producing strands comprising cut resistant fabric component.

合股线或堆叠线是通过将两种不同的线扭卷在一起形成的线,通常在加捻机上进行。 Twine or wire is wire by stacking two different wire twisted together to form a volume, usually in the twister. 合股线是本领域公知的,是通过简单的方式彼此扭卷在一起,在观察时显然合股线是由不同的线组成。 Twine is known in the art, and is a simple way to twist the volume to each other, apparently twine is composed by different line when viewed. 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 generally more flexible, so with each other by a line completely wound or with another line in a line with a line 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 wound wire having a sheath / core structure, not twine.

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。 Cut resistance by the multifilament yarn formed by the continuous organic filaments adding just a few inorganic filaments to improve. 实际上,加入仅仅1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 one metal filament is added to significantly improve the fabric made from these lines of 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。 But we hope to tow as much organic compound added this line to provide a line of binding force and make inorganic reinforcing wire can be processed in the knitting equipment, although there is no inorganic or metal filaments.

通常,结合力是通过扭卷向连续长丝线提供的。 Typically, the binding force is provided by twisting the volume to continuous filament line. 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 only some of the many problems unique inorganic filaments with filament wire having a plurality of combinations of the larger filaments of the multifilament. 较大的复丝已经具有一定水平的扭卷以提供其结合力。 Twisted multifilament large volume has a certain level in order to provide its binding force. 当小的无机长丝线与较大的复丝组合时,额外的扭卷被加入复丝中。 When the small and large inorganic filaments multifilament line combination, the extra volume is added twist multifilament yarn. 这导致在最终线中不可接受水平的扭卷,据说这种线太活跃以致不能有效地纺织成织物。 This leads to an unacceptable level in the final lines twisted around, it is said that this line too active can not be effectively woven into fabric. 也就是说,这些线具有过多的扭卷,以致如果要将线的任一端用最小的张力保持在一起,该线将倾向于自身卷绕而形成结。 In other words, these lines have too much twist roll, so if you want to either end of the line held together with a minimum of tension, the wire is wound itself will tend 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.

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/英寸的扭卷。 Strands of the present invention comprises a first multifilament continuous organic filaments, having in the first direction 0.5-10 rev / inch roll twist. 合股线还包含含有1-5个连续无机长丝的第二种线。 Twine further comprises a second line containing continuous inorganic filaments 1-5. 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卷绕方向相反,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 strokes / inch plied together in a second direction, said second winding direction opposite to the direction of the first line, the effective level of +/- 5 ply transfer / inches of twine. “有效合股水平”表示每英寸的转数的数学总和,其中复丝卷绕方向是负的,合股方向是正的。 "Effective partnership level" means the sum of the number of mathematics turn per inch, which multifilament winding direction is negative, the partnership direction is positive. 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 rev / inch, twine partnership level in the opposite direction was 7 rev / inch, the effective level of partnership -5 + 7 = 2 r / 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 turn / inch, twisted strands in the opposite horizontal direction is 2 turn / inch, the effective ply-level transfer -4 + 2 = -2 / inch.

希望有效合股水平-2至2之间,优选有效合股水平是正的。 We hope that the level of effective partnership between -2 and 2, preferably an effective partnership 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。 That being able to provide an effective level of ply adhesion and greater mixing small inorganic line between the larger multifilament, which is due to the continuous filament multifilament twisted cord at partial solution during winding.

复丝连续长丝线应该具有至少4克/旦的拉伸强度,优选该线含有防火性长丝。 Multifilament continuous filament wire should have at least 4 g / den tensile strength, it is preferable that the line contains a fire resistant filaments. 合适的防火性长丝包括从芳族聚酰胺生产的那些,例如聚对苯二甲酰对苯二胺(PPD-T)、聚间苯二甲酰间苯二胺(MPD-I)和其它高强度聚合物例如聚亚苯基苯并异噁唑(poly-phenylenebenzobis oxazole)(PBO)和/或这些纤维的共混物或混合物。 Suitable fire resistance ranging from aramid filaments produced by those, such as poly-p-phenylene terephthalamide phenylenediamine (PPD-T), poly-m-phenylene isophthalamide (MPD-I) and other high strength polymers such as polyphenylene benzisoxazole (poly-phenylenebenzobis oxazole) (PBO) and / or blends or mixtures of these fibers. 具有至少20克/旦的拉伸强度的连续复丝是优选的,优选的高强度耐切割性长丝是由PPD-T制成。 Continuous multifilament yarn has at least 20 g / d of tensile strength is preferred, preferred high strength cut resistant filaments are made from PPD-T. 复丝还可以包含一些其它材料,其含量使得由于所述其它材料引起的耐切割性降低是可接受的。 Multifilament yarn may also comprise some other material, in an amount such that the other material caused due to the cut resistance is lowered acceptable. 例如,与耐切割性长丝组合或除了耐切割性长丝之外,复丝可以还含有至多20重量%的尼龙长丝以改进耐磨性。 For example, with a combination of cut resistance filament or filaments in addition to cut resistance outside the multifilament it may contain up to 20% by weight of nylon filaments for improved abrasion resistance.
