1. 필라멘트

합성 섬유 제조에서 방사 성형 및 후처리 후 방사 유체(용융 또는 용액)는 필라멘트라고 하는 수 킬로미터 길이의 섬유를 생성합니다. 필라멘트에는 모노필라멘트, 컴파운드 필라멘트 및 커튼 필라멘트가 포함됩니다.

(1) 모노필라멘트
원래는 단공 구금에 의해 방사된 연속적인 단섬유를 말하지만, 실제 응용에서는 3~6개의 구금에 의해 방사된 3~6개의 단섬유로 구성된 몇 개의 구멍이 있는 필라멘트를 포함하는 경우가 많다. 거친 합성 섬유 모노 필라멘트 (직경 0.08 ~ 2mm)는 강모라고하며 로프, 브러시, 일일 메쉬 백, 어망 또는 산업용 필터 천을 만드는 데 사용됩니다. 더 미세한 폴리아미드 모노필라멘트는 투명한 여성용 양말이나 기타 고급 니트웨어를 만드는 데 사용됩니다.

(2) 복합 실크
수십 개의 단일 섬유로 구성된 필라멘트. 화학 섬유의 복합 섬유는 일반적으로 8~100개의 단일 섬유로 구성됩니다. 대부분의 직물은 복합 실크로 만들어집니다. 이는 여러 개의 단일 섬유로 구성된 복합 실크가 동일한 직경의 단일 실크보다 유연하기 때문입니다.

(3) 커튼와이어 타이어
코드직물을 제조하는데 사용되는 100개 이상에서 수백개 이상의 단섬유로 구성된 실크 스트립으로 일반적으로 코드와이어로 알려져 있다.

2. 스테이플 섬유

The product of the chemical fiber is cut into a few centimeters to a dozen centimeters in length, this length of fiber is called staple fiber. According to the different cut length, staple fibers can be divided into cotton staple fiber, wool staple fiber, medium length staple fiber.

(1) cotton staple fiber
The length is 25 ~ 38mm, the fiber is fine (the linear density is 1.3 ~ 1.7dtex), similar to cotton fiber, mainly used for blending with cotton fiber, such as cotton type polyester staple fiber and cotton fiber blending, the resulting fabric is called "poly-cotton" fabric.

(2) hair staple fiber
Length of 70 ~ 150mm, coarse fiber (linear density of 3.3 ~ 7.7dtex), similar to wool, mainly used for blending with wool, such as wool type polyester staple fiber and wool blending, the resulting fabric is called "wool polyester" fabric.

(3) medium-length fiber
The length is 51 ~ 76mm, the fiber thickness is between cotton type and wool type (line density is 2.2 ~ 3.3dtex), mainly used for weaving medium and long fiber fabrics.

Staple fibers can be blended with natural fibers as well as other chemical fibers, so the blended fabrics have good comprehensive properties. In addition, short fiber can also be pure spinning. In the production of chemical fibers worldwide, the output of staple fibers is higher than that of filament fibers. According to the characteristics of fiber, some varieties (such as nylon) to produce filament; Some varieties (such as acrylic fiber) mainly produce short fiber; Some varieties, such as polyester, have a similar ratio.

3、Coarse detail silk

Coarse detail silk is short for T&T silk, from its appearance can see the alternating thick and detailed parts, and after the silk strips dyed can see the alternating dark and light color changes. Coarse detail silk is manufactured by non-uniform drawing technology after spinning forming. The difference in the nature of the two parts of silk produced can be controlled in production, and its distribution is irregular and natural.

Coarse detail silk coarse section of low strength, large breaking elongation, strong thermal shrinkage, good dyeing, and easy alkali reduction processing, can make full use of these characteristics to develop unique textile properties. The physical properties of coarse detail silk are related to the diameter ratio of coarse detail and other factors. General coarse detail filament has higher elongation at break and boiling water shrinkage and lower breaking strength and yield. Its strong shrinkage property can make coarse detail fibers mixed with other fibers to form heteroshrinkage mixed fibers. In addition, the coarse section of coarse detail silk is easy to deformation, low strength problems should be paid attention to in the weaving, dyeing and finishing process. The initial coarse detail silk is round silk. With the development of the production technology of coarse detail silk, some special coarse detail silk has appeared successively, such as special-shaped coarse detail silk, mixed fiber coarse detail silk, micro-porous coarse detail silk and fine denier coarse detail silk, etc. They either have special feel and style, or have special absorption, and are mostly used in the development of high-grade fabrics.

4、Textured yarn

Textured yarns include all silk and yarns that have been processed through deformation, such as stretch yarn and bulked yarn.

5、Differential chemical fiber

Differential chemical fiber maintenance loanword, originated from Japan, generally refers to the original chemical fiber based on the physical deformation or chemical modification of the fiber material, it is obviously different from the ordinary chemical fiber in appearance or internal quality. Differential fiber not only improves the performance and style of chemical fiber, but also gives chemical fiber new functions and characteristics, such as high water absorption, electrical conductivity, high shrinkage and dyeing. Because the differential fiber is mainly used to improve the simulation effect, comfort and protection, it is mainly used to develop the wear textiles like wool, linen and silk, and some of it is also used to develop the decorative textiles and industrial textiles.

6、Special-shaped fiber

In the processing of synthetic fiber spinning, the fiber with non-circular cross section or hollow fiber spun by special-shaped spinneret hole is called special-shaped cross section fiber, or special-shaped fiber. At present, there are dozens of types of profiled fiber, polyester fiber, polyamide fiber and polyacrylonitrile fiber sold on the market, about 50% of the profiled fiber.

7、Composite fiber

There are two or more kinds of polymer that do not mix on the cross section of the fiber. This chemical fiber is called composite fiber, or bicomponent fiber. Because the two or more components contained in the fiber complement each other, the performance of the composite fiber is usually better than that of the conventional synthetic fiber, and it has many uses.

There are many kinds of composite fibers, which can be divided into two categories according to their morphology, namely double-layer type and multilayer type. Double-layer type includes parallel type and skin core type, multi-layer type includes parallel multilayer type, radial type, multi-core type, wood grain type, embedded type, sea island type and split type.

8、microfiber

Because the thickness of a single fiber has a great impact on the performance of the fabric, chemical fibers can also be classified according to the thickness of a single fiber (linear density), generally divided into conventional fiber, fine fiber, microfiber and very fine fiber.

9、New composite fiber

Emerging in Japan in the late 1980s, new synthetics became popular around the world with novel and unique supernatural styles and textures, such as peach leather and ultrafine powder handles. New synthetic fiber from polymerization, spinning, weaving, dyeing and finishing, sewing and other steps adopt new modification and composite technology, is a kind of natural fiber and synthetic fiber can not compare with the previous new fiber material. According to its commodity form, the new composite fiber mainly includes super fluffy type, super drape type and super fine type. According to its feel, it can be divided into silk feel, peach skin feel, ultra fine powder feel and new wool feel.
