Problems solved by technology

But air has almost no blocking effect on radiant heat, while fibers can effectively block
Therefore, the ideal warmth retention effect needs to select the appropriate fiber and maintain a large static air content in the fabric, and there is currently no relevant limit to achieve the above effect

Embodiment Construction

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0023] The invention discloses a manufacturing process of special-shaped hollow three-dimensional crimped acrylic fiber, which comprises the following steps:

[0024] (1) Change the shape of the fiber spinneret hole, and the fiber is made into an "H"-shaped hollow section;

[0025] (2) The single-component raw material is melted, passed through the hollow special-shaped spinneret, and the method of asymmetric cooling is used for spinning. During the fiber forming process, asymmetric cooling is caused around the cross-section of the fiber to form a very violent and very uniform. Under cooling forming conditions, the cross-section of the fiber produces internal stress of different sizes in different directions, and the birefringence in the axial direction produces a large difference,...

Abstract

The invention discloses manufacturing process of profiled, hollow, three-dimensional crimp and acrylic fibers and application thereof and dyeing and finishing process of fabric and comprises the process of fiber spinning, the manufacturing process of home textile fabric by utilizing acrylic fibers as weft filaments and the process of dyeing and finishing the above fabric. The profiled, hollow, three-dimensional crimp and acrylic fibers manufactured by the invention are adopted so that rigidity of fibers is reduced and fibers feel smooth and soft. Hydrophilic groups are introduced into fibrous macromolecules such that material contact angles are reduced. Moisture makes the fiber surface wet and spreads at a quicker pace. Multiple capillaries are formed between the hollow structure of fibers and fiber assemblies of fabric so that an excellent moisture conducting system is formed and moisture conducting performance of the fabric is markedly improved. The hollow structure of fibers helps loosen fiber assemblies and contains more still air so that a unique heat preservation system is formed. Heat preservation performance of the fabric is markedly enhanced so that the fabric has the heat preservation performance and is more light-weighted.

Description

technical field [0001] The invention relates to the field of textile manufacturing, in particular to a manufacturing process and application of special-shaped hollow three-dimensional crimped acrylic fibers and a dyeing and finishing process of fabrics. Background technique [0002] Since air is a good insulator, theoretically, the more air that remains relatively still in a fabric, the better it will retain heat. But air offers little barrier to radiant heat, whereas fibers do. Therefore, the ideal heat preservation effect requires selecting suitable fibers and maintaining a relatively high static air content in the fabric, and there is currently no relevant limit to achieve the above effect. Contents of the invention [0003] In order to solve the above problems, the present invention provides a manufacturing process and application of special-shaped hollow three-dimensional crimped acrylic fibers and a dyeing and finishing process of fabrics. [0004] To achieve the a...
