What is differential fiber? What kinds of categories does it have?

Newstime: 2019-12-30 18:17:06

Fiber is the prerequisite for the development of textile products. The colorful textile products require ever-changing textile raw materials. Therefore, many developers of textile raw materials want to produce small batches of fibers with different shapes and internal properties. The concept of differentiated fibers is thus formed. . And the fiber differentiation rate of a country is an important criterion for measuring a country's fiber production and scientific and technological level.

The so-called differentiated fibers are modified by physical or chemical methods based on the original chemical fibers. This type of fibers not only retains the basic characteristics of the original fiber variety, but also overcomes its inherent shortcomings. Conventional fibers are differentiated. The methods of chemical conversion include physical modification (mainly changing the physical structure of the polymer to change the properties of the fiber), and chemical modification (using copolymerization, grafting or crosslinking to change the polymer structure inside the fiber, thereby changing Fiber properties), process modification (physical or chemical methods to change fiber properties during fiber production), and comprehensive modification. If the modification period is different, it can be divided into modification before spinning and modification during spinning. Properties and modification after silk formation.

The main varieties of Aegis Differential Fiber are:

1. Shaped fiber

Shaped fiber, that is, the cross-section of the fiber is non-circular, mainly in the shape of trilobal, pentalobal, rectangular and flat, hollow and other shapes. It consists of the special method of spinning holes, expanded bonding method, composite spinning method, rolling method and Obtained by means of changes in hole shape, the special-shaped fiber has special gloss and good stain resistance, has good fluffy and breathable properties, has pilling resistance and abrasion resistance, good antistatic and moisture absorption properties, and has good Dyeing performance.

2.Three different fibers

Abbreviation for heteromorphic cross section, denier and heterocontraction fiber.

3.Composite fiber

That is, several materials with different properties are combined into a novel fiber. It has co-spinning, side-by-side, sheath-core, split, and multi-layer types (parallel multi-layer, radiation multi-layer, hollow radiation, multi-core and multi-core Layer type) and island type. The biggest feature of composite fibers is that the characteristics of various fibers are concentrated together, so that the new fibers have the common characteristics of various fibers.

4. Fine and ultra-fine denier

That is, the monofilament of the fiber is extremely fine. Because the bending stiffness of the fiber is proportional to the square of the fiber's fineness, the fine denier and ultra-fine denier fiber feel soft, and the sanded fabric has a delicate, waxy fluffy feel. You can get the ideal peach skin and suede.

5.Nano fibers

Generally, fibers with a fiber diameter less than 100nm are called nanofibers. They have better surface effects, small size effects, quantum size effects, and macroscopic quantum tunneling effects. Therefore, the fibers have the properties of absorbing ultraviolet rays and shielding electromagnetic waves.

6.High shrinkage fiber

Synthetic fibers have a boiling water shrinkage of not more than 5% and filaments of 7% -9%. Fibers with a boiling water shrinkage of more than 35% are called high-shrink fibers. It is obtained from the amorphous area. It is a fabric blended and interwoven with ordinary fibers. After boiling water treatment, it forms a three-dimensional or fluffy pattern because of the shrinkage of the fibers. The fabric is soft to the touch, light and fluffy, and has excellent thermal performance.

7. Functional fiber

It has high elasticity (spandex, PTT fiber, etc.), conductive, flame retardant, heat resistance, corrosion resistance, medical fiber, etc.


There are also colored silk, easy-dyed fiber, fancy silk and so on.
