[0039] 为了使不再使用的丢弃提升吊索装置不会对环境造成负面影响,吊索装置中的织物采用可生物降解的和/或可堆肥的织物。 [0039] In order to no longer use lifting sling discard means does not adversely impact on the environment, the fabric sling device using biodegradable and / or compostable fabric. 以下将讨论上述可生物降解的和/或可堆肥的织物。 The following will discuss the above biodegradable and / or compostable fabric. 本发明中所采用的可生物降解的材料既能确保吊索装置具有相应的承载能力,防止在提升中出现意外;同时也不会增加吊索装置的制造成本,从而使得病人可以承担得起专人专用的提升吊索装置,避免交叉感染的发生。 The biodegradable material of the present invention employed in the apparatus while securing the sling has a corresponding bearing capacity, to prevent accidents in the ascension; while not increasing the manufacturing cost of the apparatus sling, so that the patient can afford someone dedicated lifting sling means to avoid cross infection.

[0040] 尽管已显示P(3HB-co-4HB)产品易于在土壤、污泥和海水中生物降解,但是因水中缺乏微生物而使水中的生物降解速率非常慢(Saito, Yuji, Shigeo Nakamura, MasayaHiramitsu and Yoshiharu Doi,“Microbial Synthesis and Properties of Poly(3~hydroxybutyrate-co-4-hydroxybutyrate),,'Polymer International 39(1996),169-174)。因此P(3HB-co-4HB)产品的保存期限在诸如密封包装的干燥存储、清洁溶液等的清洁环境中应当是非常优良的。然而,当置于包含微生物的诸如土壤、河水、河泥、海水以及肥料和沙子、污泥和海水的堆肥的脏环境中时,丢弃的P(3HB-co-4HB)织物、薄膜和封装材料应当易于降解。应当注意的是,聚乳酸(PLA)在以上的脏环境中和环境温度下不易于生物降解,但是必须进行堆肥。首先,堆肥堆中的热度和湿度必须将PLA聚合物分解成更小的聚合物链,最后分解成乳酸。堆肥和土壤中的微生物将 [0040] Although display P (3HB-co-4HB) products are readily biodegradable in soil, sludge and sea water, but due to lack of water microbial biodegradation rate of the water is very slow (Saito, Yuji, Shigeo Nakamura, MasayaHiramitsu and Yoshiharu Doi, "Microbial Synthesis and Properties of Poly (3 ~ hydroxybutyrate-co-4-hydroxybutyrate) ,, 'Polymer International 39 (1996), 169-174). Thus P (3HB-co-4HB) shelf life of the product dry storage, such as a sealed package, the cleaning solution in the clean environment and the like should be very good. However, when placed in compost such as soil, river water, river mud, water, fertilizer, sand, sludge and water containing microorganisms when dirty environment, dropped P (3HB-co-4HB) of fabric, film and packaging material should be susceptible to degradation. It should be noted that polylactic acid (PLA) in the above dirty environment and not readily biodegradable at ambient temperature, but must be composted. first, heat and humidity of the compost heap PLA polymer must be broken down into smaller polymer chains, and finally decomposed into lactic acid. compost and soil microorganisms will 小的聚合物片段和乳酸作为养分而消耗了它们。因此,诸如具有PLA的P(3HB-co-4HB)产品的聚羟基烷酸酯(PHA)混合物应当增强了由PHAs-PLA的共混物制成的产品的降解。另外,由PHA和PLA的共混物制成的产品应当已经增强了在清洁环境中保存期限。然而,在过去的10年,PLA的价格已经大幅度地降低到只比诸如聚丙烯和PET聚酯的合成聚合物稍高一点;与此同时,PHAs的价格继续保持比PLA的高2到3倍,该PLA可大规模地由乳酸合成。PHAs有具有特定碳源的细菌制成,且必须采用溶剂从细菌提取。因此,在商业上无法实现将超过25%的PHA与PLA混合,以熔融挤压形成产品,诸如纺织织物、针织和无纺织物、薄膜、食品包装容器等。 Small polymer fragments and lactic acid as nutrients consumed them. Thus, as polyhydroxyalkanoate (PHA) having a mixture of PLA-P (3HB-co-4HB) the products should be increased by a blend of PHAs-PLA degradation products made of. in addition, products made from blends of PLA and PHA should have been enhanced in a clean environment in the period. However, over the past 10 years, the PLA has significantly reduced the price to only ratio of synthetic polymers such as polypropylene and PET polyester is slightly higher; At the same time, the price of PHAs keep 2 to 3 times higher than the PLA, the PLA may have a large scale synthesis of lactic acid having a particular carbon source .PHAs made of bacteria, and bacteria from the solvent extraction must be used. Thus, commercially can not achieve more than 25% of the PHA and PLA are mixed to form a melt-extruded product, such as woven fabrics, knitted and nonwoven fabrics, films, food packaging containers.

[0045] 如表I所示,9 ii m的纯(100% )PBAT薄膜(样品I)在MD方向具有良好的伸长率且在CD方向上的断裂伸长率高达300%以上。 [0045] As shown in Table I, 9 ii m pure (100%) PBAT film (Sample I) having a good elongation at break in the MD direction and the elongation in the CD direction up to 300%. 不能对样品I到5执行顶破强度测试,因为所有的这些薄膜和层压结构的弹性的非常好,在测试过程中不会断裂且在测试后也不会表现出变形。 5 Sample I can not perform the bursting strength test, because all very good elastic films and laminates of these structures, does not break during the test and after the test does not show deformation. 样品I的透水蒸汽速率相当好,为每24小时3380g/m2的,同时静压头为549mm。 Sample I water vapor permeable rate is quite good, per 24 hours 3380g / m2, while the static head of 549mm. 具有20%碳酸钙(CaCO3)的PBAT薄膜(样品2)具有与样品I类似的数据,其中WVTR和水头都相对更低。 PBAT film (Sample 2) with 20% calcium carbonate (CaCO3) having similar data sample I, wherein the WVTR and the head are relatively lower. 预计与样品I和2类似的且具有6 um或以下更小厚度的PBAT薄膜也具有良好的伸长率和更高的WVTR,尽管水头可能更低。 Sample I and 2 are expected to like and having more or less PBAT 6 um film having a small thickness is also good elongation and higher WVTR, although the head may lower. 熔喷样品3包含80%的Vistamaxx®(基于Vistamaxx聚烯烃的聚合物具有高弹性且通过ExxonMobil制成)和20%的PP,因为该织物是适度开放的,因此具有约300%的MD和⑶伸长率以及每24小时8816g/m2的高WVTR。 Meltblown Sample 3 containing 80% by Vistamaxx® (Vistamaxx polyolefin-based polymer having a high elasticity and is made by ExxonMobil) and 20% PP, because the fabric is moderately open, and therefore about 300% of the MD and ⑶ per 24 hours elongation and high WVTR 8816g / m2 of. 尽管MB Vistamaxx织物不是生物降解的,但是它是有可能从生物降解聚合物制成的一种弹性无纺材料的示例,所述生物降解聚合物诸如具有非常高伸长率和形变恢复能力的PBAT和其它生物降解聚合物。 Although MB Vistamaxx fabric is not biodegradable, but it is possible example of an elastic non-woven material made from a biodegradable polymer, a biodegradable polymer such as a PBAT very high elongation and strain recovery capacity and other biodegradable polymers. 样品3的水头相当高,为1043mm,表明其具有良好的阻隔性能。 Sample 3 of a relatively high head, is 1043mm, indicating its good barrier properties. 应当注意的是,将20%的PP添加到Vistamaxx聚合物颗粒,并且在共混物喂入MB挤压机之前进行物理混合,且进行熔融以使得Vistamaxx MB织物不会太黏。 It should be noted that the addition of 20% of PP to Vistamaxx polymer particles, and feeding the blend before physical mixing extruder MB and MB melt so that the fabric is not too sticky Vistamaxx. 如果熔喷100%的Vistamaxx,则将非常黏,且可能在滚压中结块,且难于在后续的层压或使用中展开(un-wind)。 If 100% of the meltblown Vistamaxx, will be very sticky, and may agglomerate in the roll, and the laminate is difficult to expand or subsequent use (un-wind).

[0046] 与仅有Vistamaxx相比,使用热熔粘接剂且具有Vistamaxx的纯PBAT和包含20%的CaCO3的PBAT的层压结构显著增加了MD和⑶韧性。 [0046] Compared with Vistamaxx only, and having a hot-melt adhesive and PBAT pure Vistamaxx PBAT laminated structure comprising 20% ​​of CaCO3 and significantly increases the MD ⑶ toughness. 该样品还具有非常高的MD伸长率和尤其高的⑶伸长率(样品4为390%,样品5为542% )。 The sample also has a very high elongation and MD ⑶ particularly high elongation (Sample 4 was 390% sample 5 542%). 样品4和样品5还具有显著高的MVTR值,分别为每24小时1671和1189g/m2,且具有高水头,分别为339和926mm水。 Samples 4 and 5 also has a significantly higher MVTR values, every 24 hours, respectively 1671 and 1189g / m2, and has a high water head, respectively 339 and 926mm water. 再次应当注意的是,PBAT薄膜已经能直接挤压涂层到MB 100% Vistamaxx上或具有一些PP的MBVistamaxx上且使用或没有使用热熔粘接剂,并且挤压涂层已经允许使用更薄规格的PBAT薄膜,低至4或m,由此具有更高的MVTR,但是可能具有更低的水头。 It should again be noted, can have a thin film of PBAT extrusion coating directly onto the MB 100% Vistamaxx or with or without the use and hot-melt adhesive on PP MBVistamaxx number, and pressing the coating has been allowed to use thinner gauge PBAT of the film, or up to 4 m, whereby the higher the MVTR, but may have a lower head.

[0048] 当将两层SB PLA熔粘接结合在一起而形成样品9时,MD和⑶韧性和顶破强度实质上是一层结构的样品6的两倍。 [0048] When bonding the two layers together SB PLA melt adhesive to form the sample 9:00, MD toughness and ⑶ and bursting strength is substantially double-layer structure of the sample 6. 对应从110g/m2SB PP产生的病人提升吊索的断裂伸长率(%伸长率)的目标MD和⑶韧性分别至少每5cm为200和140N,MD和⑶中的伸长率值至少都为40%。 Corresponding to the lifting sling from a patient 110g / m2SB PP produced elongation at break (% elongation) of the title MD toughness, respectively, and at least every 5cm ⑶ 200 and 140N, and MD elongation values ​​are at least ⑶ 40%. 如表I所示,两个粘接结合的SB PLA层的MD韧性为215N,但⑶韧性仅为所需级别的50%。 As shown in Table I, two adhesive MD toughness SB PLA binding layer is 215N, but only 50% of its toughness ⑶ level. 而且MD和⑶的断裂伸长率比40%的所需最小值要低得多。 And Elongation at break MD ⑶ required and 40% is much lower than the minimum value. 能通过在SB织物挤压之前将PLA与5到60%的PBAT或优选地20到50%的PBAT共混,以增强SB PLA的MD和⑶伸长率。 Before the fabric by squeezing SB PBAT blended PLA and PBAT of 5-60% or preferably from 20 to 50%, in order to enhance and MD elongation SB ⑶ the PLA. 另外,可将PBAT和PBS与PLA共混以获得具有所需MD和⑶韧性和伸长率值以及热暴露后稳定性的织物。 Further, PBS and PBAT may be blended with PLA to obtain the desired fabric having MD and ⑶ toughness and elongation values ​​after thermal exposure and stability. 另外,可通过非热点压延的工艺粘接SB长丝网,以获得更大的多方向强度和伸长率以包含水刺缠结式和针刺式。 Further, by bonding process SB hot rolled long non-screen, multi-direction to obtain greater strength and elongation to include hydroentanglement and needle type of formula. 能生成110g/m2和更大重量的针刺SB PLA而不需要将两个或多个SB PLA织物层压或粘接结合在一起以获得所需的强度和伸长率值。 You can generate 110g / m2 and greater weight of the SB PLA acupuncture without the need for two or more SB PLA fabric laminate or adhesively bonded together to obtain the desired strength, and elongation values.

[0049] 还显示由诸如PLA的可生物降解/堆肥的织物制成的吊索,从原材料阶段到工厂的聚合物形成,所产生诸如二氧化碳的温室气体排放要低得多。 [0049] As also shown, formed of a sling made of PLA biodegradable / compostable web such as a polymer from the raw material stage to the plant, the greenhouse gas emissions such as carbon dioxide is much lower. 例如,生产PLA聚合物中,每千克聚合物产生I. 3千克的二氧化碳,相应的,生产每千克PP将产生I. 9千克的二氧化碳以及生产每千克PET将产生3. 4千克的二氧化碳。 For example, in the production of PLA polymer, the polymer produced per kilogram I. 3 kg of carbon dioxide, the corresponding production per kg of PP to produce I. 9 kg per kg of carbon dioxide and the production of PET will generate 3.4 kg of carbon dioxide. 而且从原料阶段到聚合物工厂的生产中,PLA使用更少的非可再生能量,生产Ingeo牌PLA中,每公斤聚合物使用42兆焦耳的非可再生能量,与之相比的PP生产中,每公斤聚合物使用77兆焦耳的非可再生能量,PET生产中,每公斤聚合物使用87兆焦耳的非可再生能量(“The Ingeo™ Journey, Nature WorksLLC Brochure Copyright 2009)。 But also from the raw material stage to the polymer produced in the factory, PLA used less non-renewable energy, in the production of PLA in Ingeo, per kg polymer using a non-renewable energy of 42 mJ, PP production compared with the per kg polymer using 77 megajoules non-renewable energy, PET production, 87 per kg polymer using a non-renewable energy MJ ( "the Ingeo ™ Journey, Nature WorksLLC Brochure Copyright 2009).

[0050] 所述吊索装置由无纺的可生物降解/堆肥的材料制成,典型的为PLA、或主要部分为PLA加少量的PHA的共混物、或主要部分为PLA加少量的PHA和PBAT的共混物、或主要部分为PLA加少量的PHA、PBAT和PBS的共混物、或主要部分为PLA加少量的PBAT和PBS的共混物、或PBAT和PBS的共混物。 Made [0050] The nonwoven slings may be degraded by means of biological / compostable material, typically a PLA, PLA or a major portion of a small amount of PHA blend, or a substantial portion of PHA plus a small amount of PLA PBAT and a blend of PLA or a substantial portion of a small amount of the PHA, and PBS PBAT blend, or a substantial portion of PLA and PBAT PBS plus a small amount of a blend, or a blend of PBAT and PBS. 将吊索裁剪成更加符合病人I的体型,为使病人更觉舒适,在吊索10中还设置有标枪形部分16。 The rope was cut into a size more in line I of the patient, as the patient feel more comfortable in the sling 10 is also provided with a dart-shaped portion 16.
