Production technical secret of FR fabric

The importance of flame retardant fabrics in today's industrial world is self-evident. However, only by gaining an in-depth understanding of the manufacturing process of flame-retardant fabrics, companies can make the choice of the most suitable overalls fabrics for employees. Each industry has its own standard of care for the choice of fabrics. The factors such as fabric strength, breath ability and flexibility are not the only criteria. For high-risk industries, it is more than that. It must be able to cope with the challenges of various working environments. The functional requirements of fabrics must meet the needs of special environments such as heat resistance, fire resistance, and acid and alkali resistance. Since these functions must be incorporated into the fabric, the fabrics of different properties will be different in the manufacturing process. What is the manufacturing process for the flame retardant fabric? Here is a brief introduction to the process for everyone.

1.fiber selection and mixing
The production of fabrics lies in the choice of raw materials. For the flame retardant, many raw materials are extracted from the fibers, and the characteristics of fiber strength and color are extracted. The selected cotton bags are mixed together to obtain the improvement of yarn quality and strength.

2. combing

The removal of foreign matter is carried out on the basis of the selection of raw materials to ensure the quality of the yarn.

3 rotary cutting

Wrapping the yarn on the canister provides easier handling and lubrication of the fabric during the shearing process. This stage is to improve the fabric properties, which in turn improves the quality of the fabric.

4. fabric manufacturing

The next stage after fiber selection is the most important part of further ensuring the strength, quality and comfort of the fabric.
The prepared yarn is woven into the fabric, where attention needs to be paid to the fabric structure, the yarn tension, and the width of the loom used. These guaranteed consistency ensures the high quality structure and optimum performance of the fabric.

5.Dyeing
At this stage, the fabric is processed through multiple steps including singeing, desizing, scouring, bleaching and mercerizing. To make the fabric smooth, it is undeniable that in these processes, the flame retardant effect will be reduced. Good flame retardant fabric manufacturers can minimize losses at this stage. The dyeing process can then be started to ensure that the customer's color requirements for the fabric are customized.

6.FR performance blending

This is a strictly regulated and complex process, with the appropriate addition of chemical auxiliaries applied to fabrics.

7. finishing

Once the above treatment is complete, the fabric can be inspected to ensure that the fabric meets a variety of demanding flame retardant experiments.

Note:

After specifying the fabric of the flame retardant overalls, it is important to choose a reliable flame retardant fabric supplier to ensure quality. Due to the uneven quality of various basic materials or blanks on the market. In addition to differences in fiber quality, width, weight, shrinkage, strength, hue and color, many flame retardant fabric suppliers have difficulty ensuring fabric consistency and functional reliability.
