数十年来，Lurex等金属涂层纱已获得市场的广泛认可。当前有一种趋势是将这类纱线织入面料中，以获得光泽和花式效果。这些纱线采用特定的纱线组合，已在从家纺到时装的各个市场获得了广泛应用，包括鞋袜加工。

市场总是不断寻求独特的花式产品。秉承这一理念，SSM开发了一种利用空气包覆工艺创造新组合的创新方法。 SSM XENO-AC 不仅可以生产标准空气包覆纱，而且还能生产复杂的纱线，将Lurex纺入各种长丝中，例如涤纶和锦纶的拉伸变形丝(DTY)或全拉伸丝(FDY)。这些纱线将赋予针织或机织面料成品出色的光泽度和无可比拟的优点。在此生产流程中，Lurex丝与一根或多根长丝一起穿过气压喷嘴，然后进行并网。图1、2和3显示出特殊设计的成纱路径，以将金属涂层丝顺利、稳定地从原料卷装中直接喂入。

包覆Lurex的长丝可减少纱线致痒性，与直接使用纱线相比，使用这种纱线加工出的针织或织造面料手感更柔软。包覆长丝还能保护Lurex免受摩擦伤害，避免在后道工序中断裂。对于某些产品而言，空气包覆工艺可替代成本高昂、生产速率低下的传统Lurex包机工艺。Lurex空气包覆工艺的典型生产速度大约是机械包覆的20倍。此外，还可将氨纶纺入纱线，通过增加弹力来改善面料性能，获得既有光泽又有弹性的面料，这种面料常用于生产牛仔布、长袜和短袜。图4为机织面料，而图5是各种由长丝和Lurex制成的纱线卷装和面料样品。

客户可对已有的XENO-AC进行升级改造，以将标准工艺轻松改造为可加工Lurex的工艺。 SSM DP5-T 空气变形机（图6）同样可以升级改造，这在生产新型花式纱方面为厂家提供了很高的灵活性。

Lurex是Lurex Company, Ltd.的注册商标名

空气包覆工艺通过让变形丝和氨纶复合来生产弹性纱。这两种纱线被送入一个网络喷嘴，并在空气压力的作用下网络在一起。一根或多根拉伸变形丝(DTY)以最小的张力超喂进入空气喷嘴，并形成网络点。在空气包覆工艺中，会对氨纶丝施加特定的牵伸比，从而形成最终产品所需的弹性。空气包覆纱(ACY)和机械包覆纱(CCY)在结构上截然不同。空气包覆纱(ACY)是由网络点和开口段交替组成的结构（图1），而机械包覆纱(CCY)则是由长丝围绕氨纶丝缠绕而成（图2）。

机械包覆工艺是通过让包覆丝围着芯丝缠绕来生产包覆纱，从而保证最佳的均匀度和包覆质量。然而，这种工艺的加工速度非常缓慢，生产成本也很高，在生产用于服装面料的细支纱时尤甚。

因为空气包覆工艺是将DTY和氨纶网络在一起，而不是捻缠在一起，所以效率要远高于机械包覆工艺。空气包覆工艺消除了机械包覆工艺需要高速转动的限制因素，其生产速度通常要高出机械包覆工艺30到50倍（图3）。

由于机械包覆纱工艺在生产高纱支包覆纱时存在高转速和低效率的问题，每生产1千克纱线所需的能耗远高于空气包覆纱工艺，其结果是成本也更高（图4，计算基于中国工厂，20D绵纶DTY+20D氨纶丝，牵伸比3.0；空气包覆纱生产机器为SSM XENO-AC；机械包覆纱生产机器为SSM NOVA-CS；准备机器为SSM FM1）。

此外，机械包覆纱工艺要求将外包纱预先卷绕在有边筒管上。因此，该工艺是两步工艺，而空气包覆是一步工艺，无需额外的准备工序。SSM自动落纱系统提高了生产率，单锭独立设定和独立驱动超喂罗拉则可在生产小批量产品时实现极高的成本效益和灵活性。SSM空气包覆纱机可通过可控的预张力和卷绕张力，极其精确地控制纱线质量，是纱线制造商生产卓越性能纱线的理想选择。空气包覆工艺消除了传统包覆工艺对转速要求较高的限制因素。SSM空气包覆工艺是一项成熟技术，目前全球共有800多台空气包覆纱机以及超过22 000个锭位在客户工厂运行。

空气包覆纱因其优良的弹性恢复性能而被广泛用于弹力牛仔布，尤其是用作其纬纱（图5）。SSM还开发出将Lurex（金银丝）与空气包覆纱组合使用，或在同一纱线中使用两根氨纶丝，使超弹力牛仔布具有更高的弹性恢复。这些纱线可满足受应力约束下的高弹性恢复要求，应用于工业领域，如松紧。当用于袜类时，空气包覆纱还可兼顾用户对裹紧度和出色舒适性的要求。

空气包覆工艺不仅能以优异的效率创造经济效益，其所生产的空气包覆纱还具有品质上乘，性能出色的优点，因此，不管您要生产何种弹性纱，这都是一种极具吸引力的解决方案。此外，SSM还提供一系列经过现代化改造的机械包覆纱机：用于单包的NOVA-CS（图8）以及用于双包的NOVA-CD，此类机型可提供最高的包覆质量。

How densely and accurately a yarn is wound up when manufacturing dye packages is crucial to the color quality and the productivity of the dyeing process. SSM is setting new benchmarks in this area with the high-precision backpressure system preciforce. Dye packages with all kinds of yarns thus show a significantly better dyeing behavior. As such, in the production of cotton dye packages the effective package density can be increased and processed with a very low density tolerance of up to +/-1 g/l. The package build-up is extremely uniform, which gives the customer two advantages: more yarn per package and therefore increased production per dyeing process, as well as a consistent color quality. The crucial factor – the yarn density – is now an independent value that can be entered and regulated on the operating unit of the precision winding machine. The backpressure system preciforce is offered as an option on new winding machines XENO-YW, YD, PB, TU and AC and can easily be retrofitted on older models of the specified machine types.

到目前为止，在市场上仍然寻求不到全自动缝纫线成型绕线机。由于待加工的纱线种类繁多，纱管尺寸和用途繁杂：这导致全自动绕线机的标准化设计变得非常困难，客户只能选择成本极高的定制绕线机。但这并不意味着手动更换纱管的绕线机就是缝纫线领域的最佳解决方案。

正因如此，一家亚洲缝纫线生厂商决定使用284锭丝丝姆TK2-20-TT绕线机替换其“手动绕线机”。通过这一举动，公司的产能提高了100吨/月，达到了300吨/月的目标。不仅如此：公司还可能将达到产能所需的锭子数量减少50个，并将运行整个系统所需的人员数量减少60%。通过此项投资，仅人工成本一项，公司每年可以减少约3万瑞士法郎的支出——由于该公司位于新兴工业化国家，这一成果备受瞩目。

使用TK2-20-TT绕线机短短14个月之后，公司即可收回成本。由于其非常精确的计长功能及整个系统更低的能耗，客户可以额外获得每年15万瑞士法郎的收益。

Fancy intermingling option
This option creates commingled yarn with fancy color effects. It is available for the DP5-T, making this machine even more versatile, and for the new SSM air-covering machine, the XENO-AC. It consists of a high-speed valve attached to an intermingling jet body that stops and restarts the air flow at a very high pace.

The principle is not new, but its availability on SSM single- position machines makes it much more attractive for users. Intermingled fancy yarns are generally produced in small to medium lot sizes. There is no need to dedicate a complete machine side for producing a small quantity, rather, only the necessary positions are used, which gives users the added flexibility they want.

Several types of fancy effects can be combined, for instance slub and VARIO, to produce even more complex design effects. Slubs in conjunction with VARIO effects can also be combined with the elastane feeding device to produce elastic air-textured yarns. The whole range of SSM devices and options allows for new types of designs, directly at the yarn stage, making the downstream processes (weaving, knitting) simpler and giving yarn producers powerful means of diversifying their offer and enhancing their competitiveness.

Part 3: High-speed valve option
Another option available on the SSM air-texturing machine is the so-called high-speed valve, which can completely stop the air supply for a defined interval. This specially designed high-speed electro-valve is installed at the compressed air input, before the texturing jet. It allows creating a new kind of fancy effect in which the ATY shows successive non-textured lengths contrasting with the duller textured lengths, giving the appearance of shiny flashes. When texturizing threads of different colors together, the air interruption makes for a color-change effect, showing one or the other color in an alternating sequence.

Part 4: fancyflex™ AIR option
Since one aim of air texturing is to create imitation of natural fibers, the fancyflex™ AIR option was developed to imitate the natural irregularities shown by linen, silk and other yarns. This option works by producing neps and texture variations present in natural yarns but using inexpensive materials like polyester. Our fancyflex™ VARIO option combined with a torque jet to false twist the threads offers users a new type of fancy effect. This setup is a way to easily control the characteristics of the effect. The prominence of the neps and the distance between them can be controlled in order to achieve the desired effect in the fabric.

fancyflex™ VARIO
In order to be able to create longer effects and new kinds of effects, SSM developed a new device: the fancyflex™ VARIO. Featuring hardware and software specially developed in house, it provides controlled speed disturbances directly to the overfeeding godets, which are perfectly synchronized.

By controlling and changing the overfeed of a single component of a yarn, users can change the resulting dullness and also the final color of the ATY. Used on a single-color ATY, lengths with higher overfeed, which appear duller, will be produced along with lengths with lower overfeed, which appear shinier. Used on a single black or white thread, the shade of the yarn can be changed from darker to lighter – slowly changing, producing a shading effect or a 3D effect. When VARIO is used on several threads of different color, several colors and shades can be produced for a single air-textured yarn.

The fancy effects shown beside were created using a rather simple two-step cycle with two different overfeed levels, some with a random time setting.

To further support users in developing unique fancy effects, SSM developed the pattern mode. It provides a sequence of up to 50 different steps. The overfeed level and duration can be set for each step, allowing the creation of special repeating patterns.

fancyflex™ III slub device: slub effect at its best
SSM has refined and expanded the capability of the slub device. It can now handle two different yarns e.g. different colors resulting in an ATY showing successive slubs of two different colors or sizes. Proper dispatching of the slubs in the woven fabric is critical because this plays an integral role in the final visual effect. If the distance between slubs does not vary enough, an unwanted pattern on the woven or knitted fabric will result. To solve this problem, the cycle time of SSM slub device constantly and automatically changes by an adjustable random factor of up to 100%.

To give yarn manufacturers full control of slub distribution, SSM created the so-called “pattern mode.” It allows users to control the distance variation by editing a sequence of up to 40 steps, or so up to 40 consecutive slubs, that will repeat in a loop, allowing full control of the final fabric design. The pattern mode also gives greater flexibility when processing two colors of slubs because the user can choose which color to use for each of the 40 steps.

This powerful mode of control opens the door to specific designs that are not possible using the more conventional random mode, like slub degrade, which progressively increases or decreases the distance between slubs.

The maximum length of the slub is limited by the fancyflex™ III slub device, as it can only accumulate a certain quantity of yarn before it must be released.

除digitens™数码张力(SSM在线纱线张力调节)和DIGICONE® 2数码卷绕第二代(SSM分步精密卷绕)等要素外，背压力系统对络筒机的完美纱线卷装成型是非常重要的影响要素。背压力对需要达到的卷装密度有重大影响。背压力系统越精密，卷装密度就会得到越好的控制，从而实现最佳的卷装成型。全球络筒机器上的标准背压力系统，如气动式，电子-机械式或机械式系统，都遵循预先定义的曲线，在生产中经常出现的干扰因素是无法用这些系统加以纠正的。

因此，SSM开发出全球首个能连续调节接触压力并始终能避开干扰因素的背压力系统。

preciforce™ - 全球独一无二的背压力系统 
preciforce™ 是首个且仅有的能精准调节200-8,000厘牛范围接触压力的络筒机背压力系统，不管是卷绕松式筒子还是卷绕紧式筒子。由于这一创新的设计，在络筒机上通常使用气动或机械背压力系统而需要手动调节就再也没有必要了。由于其紧凑设计，功能强大的preciforce™精密背压力系统可以很容易地对现有所有类型的SSM XENO机器进行升级改造。

除了所有上述优点外，preciforce™精密背压力系统是完全免维护的，能耗更低，且系统的自校准进一步提升了preciforce™精密背压力系统的优势。

SSM preciforce™ 精密背压力系统是SSM XENO-YW, -YD, -PB 和 -AC机型的可选用件。

纱线以及卷装的多样性 - 特殊挑战
问题是：络筒机通常不能够直接生产出易于染色的卷装，这是由于存在粗支纱，低支纱，粗糙纱细，光洁纱线，圆柱形卷装以及圆锥形卷装 … 其原因数不胜数。优异的络筒机会将所有的参数都考虑进去，同时，能持续稳定地生产高品质卷装。一旦纱线卷装以不理想的方式卷绕，这种状况会导致下道工序出现问题，从而使得产品处于劣势。这种劣势会消耗大量的时间与金钱，这也正是竞争激烈的纺织行业的致胜要素。因此，SSM与著名的大学合作，开发出特定的纱线排列程序，无论何种纱线，均可使络筒机能够卷绕出完美的卷装。

以图像取代实验室测试
工程师们和数学家们选择特殊的方法，他们并不是测量纱线张力，线密度，材质以及纱线直径，并将这些参数集合至复杂的公式中，而是将SSM的专业知识转化为理论，这样做能够对筒子纱的结构以及密度分布精准预测。从数论中运用这些方法，最终专业技术人员能控制络筒过程中的“混乱动态系统”。

以这套算法为基础，开发出的DIGICONE®2算法能嵌入到络筒机控制系统软件中。通过络筒过程中的高速记录以及借助X线计算机层析成像技术，最终证实了SSM在这一项目上的成功（见对比图像）。结纶：相同结构的络筒机，之前并不总能卷绕出容易染色的筒子，而通过新的软件控制，则达到了这样的目的。

创新带来的竞争力优势
由于SSM与著名大学的合作，这一想法得以最佳地实施。Karaarslan说“DIGICONE®2算法使得我们能够在络筒机的市场上保持领先地位”。目前这种算法已经成功地运用在最新一代SSM机器上，顾客也已实质性地从中获益。

What’s a stable electricity supply?

An electricity supply is characterized by frequency, magnitude, waveform and symmetry of the three-phase-voltages. If the following disturbances exceed certain limits then the quality will be affected:

• main power shortages
• jitter light
• voltage variations
• frequency variations
• slow and rapid voltage changes (over-voltage, spikes)
• unbalance of three phase voltage
• harmonic distortion

An exact definition of a stable supply is given in the European Norm (ex. EN50160). SSM assures its machine function correctly if the norm is fulfilled.

How to test the electricity supply

To test if a supply is inside the norm you have to analyse your net over a long time. Variations over the seasons have to be taken into consideration (summer/winter influences etc.). Often a weekly analyse will give you sufficient information about your net. SSM can offer a short analyse of your net. Very often though consumers know their supply. Important are the amount of main power shortages and voltage variations.

How to connect the machine to the supply

A lot of errors can be avoided by connecting a machine correctly:

• Is the grounding system of the machine correct?
• Sufficient cross section of the supply pipe?
• Avoid connecting machines of different power classes to the same main distributor.

How to protect a machine

There are a number of devices that can help to protect a machine, e.g. UPS (unbreakable power interrupt), power stabiliser, flash protector, or net filter. It is important to choose the best and most economical solution. The beside checklist will help you to choose appropriate equipment.

The ratio between double strokes and number of revolutions is kept constant for a certain diameter range. The crossing angle varies only slightly within a range of ±1°. This results in an enhanced package density that does not change with increasing package diameter. So the building of pattern zones is avoided and the package maintains a stable structure without any ribbons. Due to this stable structure, the risk of complete layers “slipping off” during the unwinding process of dyed packages, as known with random winding, is completely eliminated.

The introduction of the XENO platform opened new possibilities for optimizing the winding algorithm. Thanks to this new machine platform, SSM could release DIGICONE® 2, enabling an increase of dye package density by another 10–24% with unchanged dyeing recipes.
