Relaxation process introduction

Relaxation process introduction

After finishing is the technical treatment method of fabric color effect, morphological effects (smooth, velvet, stiff, etc.) and actual effects (impermeable water, felt, reflected, hot, non -moth, flame -resistant, etc.). Improve the appearance and feel of the fabric through chemical or physics, improve the process of taking performance or give special functions, which is the processing process of "icing on the cake" of textiles.

The purpose of the later sorting

The post -collation method can be divided into two major categories: physical/mechanical collation and chemical collation. According to the purpose of post -collation and the different effects, it can be divided into basic finishing, appearance finishing, and functional collation. The purpose of the later sorting:

1. Make the textiles wide and neat, and the size and shape are stable. Such as Ding (pull) amplitude, mechanical or chemical anti -contraction, wrinkles and thermal fixed types.

2. Enhance the appearance of textiles: including increasing the gloss and whiteness of textiles, and enhanced or weakened the fluffy of the surface of textiles. Such as adding white, rolling, electric light, ya, grinding, cutting hair and shrinkage.

3. Improve textile feel: Mainly use chemical or mechanical methods to make textiles obtain a comprehensive touch feeling such as soft, smooth, plump, stiff, thin or thick. Such as soft, hard, weight gain, etc.

4. Improving the durability of textiles: It mainly uses chemical methods to prevent damage or erosion of fiber such as sunlight, atmosphere or microorganisms, and extend the service life of textiles. Such as anti -mothing, mildeworing, etc.

5. Special performance of textiles: including textiles have certain protective performance or other special functions. Such as flame retardant, antibacterial, water refusal, oil refusal, ultraviolet prevention and anti -static electricity.

After the fabric, the development of the technology is towards the functional, differentiated, and high -end product, the processing technology diversified, and the development of the processing technology, and emphasizes the improvement of the product's taking performance and increasing the added value of the product. In recent years, various new technologies have been introduced from other technical fields (such as low -temperature plasma treatment, biological engineering, ultrasonic technology, electronic beam radiation processing, inkjet printing technology, microcapsule technology, nanotechnology, etc.) to improve processing processing Deep, get good finishing products. With the attention of human pollution and destruction, it pays more and more attention to health, advocates the "low -carbon" economy, and then organizes technical requirements for environmental protection "green" processing and produces "clean" and "low -carbon" textile products.

The basic post -collation methods of fabrics include: stable size, improvement method of improvement of appearance, compilation method of improving the performance optimization performance, the method of making the fabric obtain multi -function, high value -added method, the method of compilation of fabrics advanced, and meeting special requirements to meet special requirements. Organize. All kinds of post -finishing processes are as follows:

01 pre -shrinkage

The pre -shrinkage is a process that uses physical methods to reduce the contraction of the fabric to reduce the reduction rate. The mechanical pre -shrinking is to wet the fabric through the spraying via via via via via via via via via via it, and then squeeze the machine to increase the height of the flexion wave, and then dry it through the pine.

02 pull -out

The tension is the plasticity of the fiber, silk, wool and other fibers such as fiber, wool, etc., and gradually widen the width of the fabric to dry the sizes, so that the fabric shape can be stable and stable.


The slurry refers to the processing process of the fabric soaking and coating and drying to obtain a thick and stiff effect.

04 thermal fixed type

The thermal type is a process that enables the relatively stable process of thermoplastic fiber, blended or interlaced fabric shapes. It is mainly used to process synthetic fibers and its blended scholarships such as nylon or polyester that can easily shrink and deform after heating. The hot -fixed fabric can improve size stability and feel hard.

05 Zeng Bai

The process of adding whitening is the process of adding the whiteness of textiles to add the whiteness of the textile, also known as the addition. There are two types of white white and fluorescence.

06 Rolling, electric light and rolling pattern

Light is a process that uses the fiber to flatten the surface of the fabric or rolled out of the parallel fine oblique pattern to improve the luster of the fabric. The flat rolling light is composed of a hard roller and a soft roller. After the fabric is rolled, the yarn is flattened, the surface is smooth, the luster is enhanced, and the feel is stiff. The soft rolling light is a soft rolling point consisting of two soft rollers. After the fabric is rolled, the yarn is slightly flat, the luster is soft, and the feel is soft.

Electric light is rolled on the fabric of the rolls heated by power.

The rolling pattern is a rolling point consisting of steel rollers and soft rollers engraved with yang pattern. Under hot rolling conditions, the fabric can obtain a shiny pattern.
