[0023] 本发明技术方案的突出的实质性特点和显著的进步主要体现在以下几方面: [0023] The essential characteristics and notable progress projecting aspect of the present invention mainly in the following aspects:

[0024] 可通过不同原料、不同复合方式、不同粘合方法生产各种性能的产品。 [0024] can be obtained by different material composite manner, a method of producing a variety of different adhesive properties of the product. 纺粘法技术主要包括纺丝、成网、粘合成布三大部分,它可以将熔融纺丝的高分子材料如乙纶、丙纶、锦纶、涤纶等不同材料,以不同的复合方法如皮芯、并列、橘瓣、海岛等形成多种不同性能的复合纤维和纤网;在成布方法上由于它不同材料热性能不同,因此除了传统的热轧、针刺、水刺外,热风技术也得到应用。 Spunbonding techniques including spun, laid, bonded into three cloth parts, which can be melt-spun polymer material such as Polyethylene, polypropylene, nylon, polyester and other different materials, different methods such as a composite skin core, side by side, segmented pie, islands like plurality of different properties of the fibers and the composite web; into cloth on its thermal properties due to different methods of different materials, so in addition to the conventional hot rolling, needling, hydroentangling, hot air also it has been applied. 使纺粘布的产品变得丰富多彩,用途越来越广。 The spunbond products more colorful, use more widely. 如PE熔点为130°C,PP熔点为165°C,二种原料生产的复合纤维网可以通过专门的热风粘合设备制成非织造布,产品的柔软和舒适性极好,此类结构的复合短纤,已完全代替单组分纤维,垄断了高档卫生材料市场。 The melting point of PE 130 ° C, PP melting point of 165 ° C, two kinds of raw materials to produce composite webs may be made of nonwoven fabric through a dedicated air bonding equipment, products excellent in softness and comfort, such structures composite staple, has been completely replaced by single-component fibers, monopolized the high-grade hygiene market.

[0025] 与同类短纤产品相比,强度更高,生产中不添加纺丝油剂,产品更卫生。 [0025] Compared with similar staple products, higher strength, the production does not add spin finish, the product more hygienic. 众所周知,短纤维非织造布的强度,特别是横向强度不如纺粘法高,影响服用性能。 Is well known, the strength of the nonwoven fabric of short fibers, in particular the transverse strength is not as high spunbonding affect wearability. 短纤维生产过程中必须添加的油剂,从成分、制作过程到存放期间都会产生对产品卫生性能的不利影响;而纺粘法生产过程流程短,从纺丝到热轧都是在高温状态下生产,其间没有任何添加剂。 Staple fiber production process oil must be added, will adversely affect the performance of health products from components to the production process during storage; Spunbond production process and short process, from spinning to hot rolling are at a high temperature production, during which no additives. 因而可以确保产品更加卫生。 Thus ensuring the product more hygienic.

[0026] 有色或功能性产品可以在不降低效果的前提下,节约成本。 [0026] or a colored product can be functional without the effect of reducing cost savings. 色母粒和抗静电、抗老化、阻燃等改性剂价格较高,一般为乙纶、丙纶或涤纶切片价格的4-5倍,尽管在产品中加入的比例不高,但对成本影响人比较大。 And antistatic masterbatch, anti-aging, fire-retardant modifier higher prices, typically 4-5 times Polyethylene, polypropylene or polyester chip price, although the addition ratio in the product is not high, but the impact on the cost of who is relatively large. 由于纺粘法产品应用范围越来越广,有色、功能性要求也越来越多,双组分复合纺粘法工艺可以采用皮层加色母粒或改性剂,芯层不加的方法,同样达到有色或功能性产品的要求,而添加量仅需单组分纺粘法的50%左右,因此可以大大降低生产成本。 Since spunbonding increasingly wide range of product applications, colored, more and more functional requirements, bicomponent spunbonding process or skin modifying agent masterbatch added, the core layer may be employed without method, required to achieve the same functionality, or colored product, while only about 50% of the added amount of the one-component spunbond process, it can greatly reduce the production cost.

[0027] 也可以生产普通PP或PET纺粘产品。 [0027] can also be produced ordinary PP or PET spunbond products. 双组分生产线可以通过二根螺杆加同种原料,或者在组件安装时去掉复合分配板即可生产普通的单组分PP或PET纺粘产品。 Bicomponent production line by two kinds of raw materials with screw added, or removed when the composite distribution plate assembly is mounted to the production of ordinary PP or PET monocomponent spunbond products.

[0028] 与单组分纺粘线相比,生产成本增加不多产品附加值增加许多。 [0028] Compared with single component spunbond lines, production costs increase the number of small value-added products. 双组分纺粘线与单组分纺粘线相比,同等规模设备的差异在于一根大螺杆换成了二根小螺杆,单组分箱体换成了复合箱体,其它设备都一样;原料上计算,以PE/PP复合产品和PP纺粘布相比,PE、PP切片价格基本接近,生产成本增加不多;而目前国外双组分产品比单组分至少要贵一倍,国内销售价可以增加30-50%,因此产品附加值增加许多,具有较好的经济效益。 Bicomponent spunbond line compared with single component spunbond line, the difference is that an equally large scale equipment the two small screw into the screw, a one-component composite casing into the casing, the other devices are the same ; calculated on raw material, PE / PP and PP spunbond composite products compared, PE, PP sections substantially close price, small increase in production cost; the two-component products currently abroad than one component at least twice as expensive, domestic sales price can increase by 30-50%, and therefore increase the number of value-added products, with good economic benefits.

[0029] 双组分熔体是由两种不同聚合物构成。 [0029] The bicomponent melt is made of two different polymers. 两种聚合物熔点不同,纺丝温度亦不同。 Two different polymer melting point, the spinning temperature is also different. 在同一箱体内受同一温度影响(一般箱体温度按熔点高的纺丝温度要求高的聚合物设定),相对低的聚合物纺丝工艺温度无法把握,影响纺丝质量。 Effect of temperature by the same cabinets (cabinet temperature typically by spinning a high melting point require a high temperature polymers set) in the same, relatively low temperature can not grasp the polymer spinning process, the spinning mass impact. 本发明特别采用分配管外置,将分配管移出箱体,各个分配管温度单独设置,这样两种熔体进入纺丝箱体和纺丝组件内,停留时间非常短(基本不到传统的一半停留时间)。 The present invention particularly uses an external dispensing tube, the dispensing tube out of the tank, the temperature of each dispensing tube separately provided, so that the two melts into the spinning pack and the spinning housing, the residence time is very short (less than half the conventional basic residence time). 可以为熔体与设备之间保持较大的温差,这对比较敏感的熔体纺丝正常极有意义。 May maintain a large temperature difference between the melt and the device, which normally very sensitive sense for melt spinning.
