ADVANSA’s wetlaid fiber engineering

Advansa对于人造纤维在湿法应用中的研究

The wetlaid process is a core process at nonwoven producers that focus on uniformity, light-weight and strength.

湿法工艺是非织造布生产商的核心工艺，它注重均匀性、轻量性和强度。

Wetlaid products are suitable for many different technical applications such as automotive, filtration, medical, hygiene, wallpaper, packaging, embroidery, construction material, etc.

湿法无纺布产品适用于汽车、过滤、医疗、卫生、墙纸、包装、刺绣、建筑材料等多种不同的技术应用。

Wherever more demanding nonwoven products and papers with an outstanding uniformity and without any kind of defects are required, the wetlaid process is a good option for which fibers with good dispersion in water are essential.

由于纤维在水中良好的分散性，凡是要求均匀性优异且无任何缺陷的非织造产品和纸张的地方，湿法处理是一个很好的选择。

The dispersion of the short cut is mainly dependent on fiber type, diameters, cut length, cross section and surface characteristics.

短切纤维的分散主要取决于纤维类型、直径、切割长度、横切面和表面特性。

Polyester short cut improves the wet and dry strength, tear and burst strength and the wet dimensional stability when partially replacing wood pulp in papers and wet laid nonwovens.

在纸和湿法非织造布中，使用聚酯短切替代部分木浆时，可以提高湿强度、干强度、撕裂、爆裂强度和湿尺寸稳定性。

Depending on the end use of the final sheet, the polyester fiber percentage in the recipe can range from a few percent to almost 100%.

根据产品的最终用途，配方中的聚酯纤维百分比可以从几个百分点到几乎100%。

ADVANSA is producing specially engineered short cut fibers, which fulfill all requirements needed for such applications.

ADVANSA正在生产特别设计的短纤维，满足此类应用的所有要求。

The fibers have a specially modified surface for a rapid and effective separation.

该纤维具有特殊的改性表面，可快速有效地分散。

Therefore, using moderate shear forces, the short cut fibers are evenly dispersed in water.

因此，利用适度的剪切力，短切纤维可以均匀地分散在水中。

ADVANSA fibers can be used for processing in horizontal wire (Fourdrinier) paper machines (cut length in the range of 3 to 6mm) as well as inclined wire machines with cut lengths up to 30 mm and even higher.

ADVANSA纤维可用于长网纸机(切割长度在3至6mm范围内)以及切割长度达30毫米甚至更高的斜网纸机。

ADVANSA’s portfolio includes customized polyester fibers with modified cross-sections, colored and binder fibers.

ADVANSA的产品组合包括定制的聚酯纤维，改性的横截面，彩色和粘结纤维。

The range of the linear density is between 0,2 dtex to 17,0 dtex.

线性密度的范围在0,2 dtex到17,0 dtex之间。

Various grades are compliant with the requirements for food contact articles as defined by EFSA, BfR and FDA guidelines.

不同等级的产品符合EFSA, BfR和FDA指南对食品接触物品的要求。

Current R&D works focus on further reduction of the linear density into direction of 0,2 dtex and even finer following the requirements of filter media producers.

目前的研发工作主要是按照过滤材料生产厂家的要求，将线密度进一步降低到0,1dtex甚至更细的方向。

Further commercial types are bicomponent fibers with polyethylene terephthalate core and lower melting sheath polymer.

进一步的商用类型是含有PET芯和更低熔点皮层的双组分纤维。

For end products that are designed for compostability ADVANSA offers dispersible poly lactonic acid (PLA) fibers.

对于可堆肥的最终产品，ADVANSA提供可分散的聚乳酸(PLA)纤维。

For sustainable end uses with particular low carbon footprint and non-renewable energy consumption figures, polyethylene terephthalate fibers from post-consumer recycled feedstock are also an available option.

对于具有特定的低碳足迹和不可再生能源消耗数字的可持续最终用途，来自消费后回收原料的PET纤维也是一个可用的选择。

This environmentally friendly option is made by using an innovative recycling technology – out of raw material purchased from ADVANSA’s partner Reiling.

这种环保的选择是通过使用一种创新的回收技术——从ADVANSA的合作伙伴Reiling购买的原材料。

These are PET bottle flakes from European Collection System.

这些是来自欧洲收集系统的PET瓶片。

The traceability of the PET bottle flakes back to the bottle feed stock guarantees a high-level of quality control.

PET瓶片到瓶料的可追溯性保证了高水平的质量控制。

As an external certification for the use of post-consumer recycled raw material in the relevant fiber products, ADVANSA’s operation has been awarded the GRS-label.

作为在相关纤维产品中使用消费后回收原料的外部认证，ADVANSA的业务获得了GRS商标。

Using the state-of-the-art production technology at ADVANSA, this raw material is melted and pressed through super-fine filtration.

采用ADVANSA的最先进的生产技术，这种原料经过超细过滤熔化和压制。

In order to avoid any defects in fibers, the polymer is spun under strict process control.

为了避免纤维中出现任何缺陷，聚合物在严格的工艺控制下进行纺丝。

In further steps, fibers obtain their final physical as well as their necessary surface properties.

在进一步的步骤中，纤维获得其最终的物理性质以及必要的表面性质。

Precise cutting length is ranging from 3mm to 38mm depending on the subsequent application.

精确切割长度从3mm到38mm不等，取决于后续的应用。

Each intermediate step in the production process chain is strictly controlled, resulting in uniform product quality, which is proven by regular lab tests.

生产工艺链的每一个中间环节都被严格控制，产品质量统一，并通过定期的实验室检测。

Hence, the quality of recycled and non-recycled material is comparable.

因此，可回收材料和不可回收材料的质量是相当的。

Thanks to fully automatic packaging processes, the fibers are filled in bags or big bags on pallets, e.g., in 25 kg plastic bags, 150 kg to 400 kg big bags, or other packaging sizes upon request.

由于全自动包装过程，纤维填充在袋或大袋托盘上，例如，在25公斤塑料袋，150公斤到400公斤大袋，或其他包装尺寸的要求。
