"Polyester fabrics are easy to pilling, and cotton clothes like to deform. What kind of fiber has excellent cotton properties and polyester properties to make up for the shortcomings?"

"That's super imitation cotton"

What is super imitation cotton

The super-imitation cotton body is polyester, and the polyester content exceeds 85%. It is a differentiated functional polyester fiber, including filament cotton and short fiber imitation cotton. More vividly, the super-imitation cotton product looks like cotton (Vision), feels like cotton (touch), wears like cotton (affinity), is easier to use than cotton (easy to wash), and has the excellent characteristics of cotton-like cotton. Imitated cotton is a product of polymer spinning, spinning, weaving, dyeing and finishing, and the integration and integration of multiple technologies.

What is super-imitation cotton?

1

Imitate the characteristics of cotton fiber

1 imitating hairiness and fluffy

Polyester filaments have high bundles and smooth surfaces. In order to form a cotton-like texture on the surface, the fiber structure must be changed. At present, there are mainly several methods to improve the hairiness and bulkiness of polyester: by using an air network, the filaments are blown away, entangled to form an irregular structure, and a combination of different materials is used to form the three. -Three-dimensional curled bulky shapes.

Observing from the rough feeling, the air network of the cotton thread fineness is not uniformly deformed, and the hair feels different. The cotton-like yarns of different combinations of raw materials have uniform fineness, and the hair feel can be prominent during finishing, and generally does not affect the subsequent processes. produce.

2 imitating the moisture absorption of cotton fiber

At present, the methods to improve the moisture absorption of polyester mainly include: increasing the specific surface area of ​​the fiber with fine denier or ultra-fine denier to increase the wicking speed of the capillary; changing the cross section of the fiber, increasing the moisture permeable channel, and accelerating the moisture absorption Speed: Hydrophilic modification is performed to add hydrophilic groups to the fiber to enhance the moisture absorption capacity of the fiber.

3 imitating the gloss of cotton fiber

In order to improve the gloss of polyester and achieve the effect of cotton fiber, diffuse reflection must be formed on the surface of the fiber to reduce the light reflection ability. The method to reduce the gloss is to change the surface of the fiber to reduce the reflection of light on the surface. Or absorb part of the light to form a soft luster, use fine denier or ultra-fine denier to improve diffuse reflection ability and soften light.

Make up for the defects of cotton fiber

The characteristics of polyester used make up for the shortcomings of cotton fabrics. For example, polyester has good weather resistance, such as light resistance, heat resistance and mildew resistance, which can make up for the shortcomings of cotton fabric durability; polyester has a large initial modulus, is hard and not easily deformed, and has a good shape Remaining and can make up for it. Cotton fabrics are not easy to wrinkle, deform easily and are not wear-resistant.

It is also developed according to the different needs of users, the field of use and the needs of certain specific functions, and some even have better performance and performance than pure cotton fabrics. Using different hydrophilic agents and different cross-sectional shapes to modify the fiber, super-imitation cotton fiber has different moisture absorption, which can meet the needs of different sports.

Recycled beverage bottles and waste coffee grounds can be reused to produce super-imitation cotton fiber, bringing new environmental protection characteristics to super-imitation cotton fiber.

What about imitation cotton and imitation products?

Weaving process

Organizational structure

The cotton-like effect of super-imitation cotton fiber firstly depends on the texture of the fabric. Because the finer the fiber, the stronger the capillary phenomenon, the better the shape of the profiled section, and the better the moisture absorption. However, in the fabric structure, in order to enhance its moisture absorption, the fabric structure design should be carried out according to the different application fields of the fabric, sometimes plain weave fabric is better, sometimes twill fabric is better.

2 Warp and weft settings

Due to the special properties of super-imitation cotton fiber, the shrinkage characteristics of the fiber during the finishing process are considered. The warp and weft should be appropriately designed so that the fiber can fully reflect the thick and bulky feeling of the fabric after heat shrinkage.
