Efficient SEO Promotion Company in Bengbu: Classification Guide for Chemical Fiber Filaments and Staple Fibers

纺织品的商品归类是关务工作中的重要环节，而化学纤维的区分更是其中的关键。本文将详细解析化学纤维长丝和化学纤维短纤的区别，帮助您在报关时准确归类。

Classification of textiles is a crucial part of customs work, and the distinction between chemical fibers is particularly important. This article will provide a detailed analysis of the differences between chemical fiber filaments and chemical fiber staple fibers to help you classify them accurately during customs declaration.

化学纤维的分类及制造过程

Classification and Manufacturing Process of Chemical Fibers

化学纤维分为合成纤维和人造纤维两类，它们的制造过程决定了其最终形态（长丝或短纤）。

Chemical fibers are divided into two categories: synthetic fibers and artificial fibers. Their manufacturing process determines their final form (filament or staple fiber).

1. 生产工艺
化学纤维的成型主要有熔融纺丝、干法纺丝和湿法纺丝三种方法。理论上，化学纤维可以无限延长。

1. Manufacturing Process
The forming of chemical fibers mainly includes melt spinning, dry spinning, and wet spinning. Theoretically, chemical fibers can be extended indefinitely.

2. 合成纤维
由合成高分子聚合物制成，常见的有涤纶、锦纶、腈纶等。

2. Synthetic Fibers
Made from synthetic polymers, common types include polyester, nylon, and acrylic.

3. 人造纤维
用天然材料的纤维素制成，如莫代尔。

3. Artificial Fibers
Made from natural cellulose materials, such as modal.

长丝与短纤的区分

Distinction Between Filaments and Staple Fibers

化学纤维长丝：可以无限延长，表面光滑，织物光泽较强。

Chemical Fiber Filaments: Can be extended indefinitely, with a smooth surface and strong fabric luster.

化学纤维短纤：通常长度在25～180毫米之间，通过将长丝切断制成，织物表面有较多毛羽。

Chemical Fiber Staple Fibers: Typically 25-180mm in length, made by cutting filaments, with more fuzz on the fabric surface.

织物判断技巧

Fabric Identification Tips

1. 手感判断：柔顺光滑的多为长丝，粗糙的多为短纤。

1. Touch Test: Smooth fabrics are usually filaments, while rough ones are staple fibers.

2. 织物镜观察：无毛羽为长丝，有毛羽为短纤。

2. Fabric Microscope: No fuzz indicates filaments, while fuzz indicates staple fibers.

特别提示

Special Notes

1. 第五十五章中可能存在按短纤归类的长丝丝束。

1. Chapter 55 may include filament tows classified as staple fibers.

2. 新型纤维（如"天丝"、"牛奶纤维"）本质上仍属于化学纤维。

2. New fibers (e.g., "Tencel", "milk fiber") are essentially still chemical fibers.
