Mechanical finishing stages in Fabric processing

After the process of chemical processing such as cooking, bleaching, polishing, dyeing … the fabric is subjected to mechanical impacts causing the fabric to stretch in length, shrink in the horizontal direction, and the fabric size is narrower than the original size. In the completion stage, in addition to using chemicals (on the shaping machine), it is also possible to use mechanical methods such as stretching, pressing … in the finished fabric mechanical part, the purpose is to use mechanical methods. conditions for the fabric to return to normal state, smoothing the face to create a smooth layer of snow on the fabric to increase the insulation, insulation, softness, more porous to improve the non-creasing, improve the stability of the fabric and increase the beauty of the outside.

1  Raising process:

fabric-raising-machine is the process of finishing vwois with the purpose of creating ruffled fur on the fabric surface. The surface of the fabric is treated with the contact of brushed teeth with sharp teeth to create fur on the surface of the fabric, thereby making the fabric surface rough, soft and warm, often used in garments. keep warm in winter … ..

 

 

2 / Calendering process

It is a processing process to create a smooth fabric surface, by running the fabric through hot spindle rotating at the same time with green pressing. The shaft can be smooth or embossed to create the fabric surface as the design depends on the speed of rotation, the force or the shaft structure.

3 / Personnel department (Sanforizing):

sanforization-process Machining process creates resistance to shrinkage and laundry for fabric by mechanical methods. The fabric is run through steam and passes under the pressure of a felt conveyor and a metal shaft at an appropriate setting speed to achieve the appropriate width and density to eliminate fabric shrinkage, for stability. Good after finishing.

In addition to the mechanical finishing methods mentioned above, many chemical finishing processes or by using special chemical chemicals participate in chemical reactions or bind with fibers to create new features. for fabrics, all are also derived from diverse requirements and meet all the features for fabrics according to user needs.

4 / Crease resist or wrinkle free finishing
This method of finishing is based on the application of reaction resins that create cross-linking with cellulose fibers to overcome the shrinking and wrinkling properties of cellulose fibers. Making cellulose fibers have the same activity as synthetic fiber without losing other valuable natural properties such as sweat absorbent, breathable, moisture control and skin friendly. This is one of the finishing methods that makes the use value of cotton greatly increase in the textile sector. After the cross-linking is created inside the fiber between the resin and cellulose molecules, the fiber will have dimensional elastic properties like synthetic fiber (Elastic). This property allows fibers to be resilient to impact in different directions, helping the fabric to tend to resist or restore its shape when exerted by external forces. Helping fabrics with wrinkle resistance, shrinkage resistance.

5/ Anti-microbial finish:

Anti-microbial is a finishing technology that gives fabrics the ability to resist bacterial growth. The humid and warm environment in textile fibers encourages the growth of bacteria, which causes the spread of pathogens and the development of odors on the fabric and infects the skin of the user. For the purpose of protecting the wearer’s skin and protecting the textiles, anti-bacterial finishing technology is applied to the textile.
