ADVANSA’s wetlaid fiber engineering

Advansa关于天然纤维在湿法使用中的研讨

 

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

湿法工艺黑白织造布消费商的中心工艺,它注意匀称性、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.

湿法无纺布产品实用于汽车、过滤、医疗、卫生、墙纸、包装、刺绣、修建质料等多种差别的技能使用。

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.

由于纤维在水中精良的疏散性,但凡要求匀称性优秀且无任何缺陷的非织造产品和纸张的地方,湿法处置是一个很好的选择。

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

短切纤维的疏散次要取决于纤维范例、直径、切割长度、横切面和外表特征。

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,利用聚酯短切替换局部木浆时,可以进步湿强度、干强度、扯破、爆裂强度和湿尺寸波动性。

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%.

依据产品的终极用处,配方中的聚酯纤维百分比可以从几个百分点到简直100%。

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

ADVANSA正在消费分外设计的短纤维,满意此类使用的一切要求。

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

该纤维具有特别的改性外表,可疾速无效地疏散。

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

因而,使用过度的剪切力,短切纤维可以匀称地疏散在水中。

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范畴内)以及切割长度达30毫米乃至更高的斜网纸机。

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

ADVANSA的产品组合包罗定制的聚酯纤维,改性的横截面,黑色和粘结纤维。

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

线性密度的范畴在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.

差别品级的产品切合EFSA, BfR和FDA指南对餐饮打仗物品的要求。

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.

现在的研发事情次要是依照过滤质料消费厂家的要求,将线密度进一步低落到0,1dtex乃至更细的偏向。

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

进一步的商用范例是含有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.

关于可堆肥的终极产品,ADVANSA提供可疏散的聚乳酸(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.

关于具有特定的低碳脚印和不行再生动力斲丧数字的可继续终极用处,来自消耗后接纳质料的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.

这种环保的选择是经过利用一种创新的接纳技能——从ADVANSA的互助同伴Reiling购置的原质料。

These are PET bottle flakes from European Collection System.

这些是来自欧洲搜集体系的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包管了高程度的质量控制。

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.

作为在相干纤维产品中利用消耗后接纳质料的内部认证,ADVANSA的商业取得了GRS牌号。

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

接纳ADVANSA的开始进的消费技能,这种质料颠末超细过滤熔化和压抑。

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

为了制止纤维中呈现任何缺陷,聚合物在严厉的工艺控制下举行纺丝。

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

在进一步的步调中,纤维取得其终极的物感性质以及须要的外表性子。

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

准确切割长度从3mm到38mm不等,取决于后续的使用。

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

消费工艺链的每一其中间关键都被严厉控制,产品格量一致,并经过活期的实行室检测。

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

因而,可接纳质料和不行接纳质料的质量是相称的。

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.

由于全主动包装历程,纤维添补在袋或大袋托盘上,比方,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。

With almost 50 years of experience – founded on its heritage of DuPont – ADVANSA is well recognized with its innovative fiber production based in Germany.

在杜邦的底子上,ADVANSA拥有近50年的履历,并以其在德国的创新纤维消费而遭到普遍承认。

The company focuses on the optimal development and production of innovative as well as technologically advanced fibers.

公司专注于创新、技能先辈的纤维的优化开辟和消费。

ADVANSA allows a high productivity within the supply chain and functionalizing of the final products.

ADVANSA容许在供给链内的高消费率和终极产品的功效化。

Thanks to its responsiveness, ADVANSA reacts to changing customer demands and supports developments in order to offer and implement competitive, customized products and individual solutions.

由于其迅捷的呼应才能,ADVANSA对不停变革的客户需求做出反响,并支持定制,以提供和实行具有竞争力的定制产品和团体办理方案。

One of ADVANSA’s key values guiding the development of new products is sustainability while continually improving the safety, health and environmental performances.

ADVANSA引导新产品开辟的要害代价观之一是可继续性,同时不停改进宁静、安康和环保功能。

The company’s efforts and achievements and a wide range of fibers produced by ADVANSA have been recognized by international ecological certification and awards such as the EU Eco-label and the European Greenlight Program.

公司的高兴和成绩以及ADVANSA消费的种种纤维取得了国际生态认证和欧盟生态标签、欧洲绿光方案等奖项。
