涤锦复合纤维溶胀剂
HOLPOSON® Swell-Up
Swell-Up 是属于高分子复合纤维溶胀裂离技术范畴，既称为PA6纤维的高密度化技术，经过处理后纤维内部的空间体积得到很大程度的膨胀，此技术大幅提升了面料内部空间体积及面料的独特性能，如空间比表面积增大，溶胀裂离后化学吸附性能增强，物理吸附性等方面均得到大幅改善。为某些特种行业提供原材料与技术方案。
复合丝超高密度化的原理：利用聚酯纤维和聚酰胺6纤维不同的条件下溶胀胀长差使两个组分分离，达到产生超细的纤度。聚酰胺6在ph5.0~6.0之间溶胀大，而涤纶在酸性范围内不变，进而利用同一条件下溶胀率而不同，溶胀裂离利用化学反应使聚酰胺6产生较大的溶胀率同时发生纤维卷曲继而达到涤纶、锦纶二者组分界面分离

Polyester/Nylon Composite Fiber
Swelling Agent
HOLPOSON® Swell-Up
HOLPOSON® Swell-Up falls in the category of swelling and splitting technology of macromolecular composite fiber, which is also called densifying technology of PA6 fiber. After treatment, the internal space of the fiber is expanded to a large extent. This technology greatly improves the internal space of the fabric and the unique performance of the fabric. The increase of the specific surface area, the enhancement of the chemical adsorption performance after swelling and splitting, and the physical adsorption capability have all been greatly improved. For some special industries provides raw materials and technical solutions.
The working principle of ultra-high densification of composite fiber: Taking the advantage of the difference between the swelling lengths of polyester fiber and polyamide 6 fiber under different conditions to split the two components to produce ultra-thin size. The swelling rate of polyamide 6 is high in the range of pH 5.0-6.0, while the swelling rate of polyester remains unchanged in acidic conditions. With this advantage, the polyamide after chemical reaction swells extensively and crimps, thus separating itself from polyester.
