Finishing Process And Finishing Agent For Wool Textile Fabrics

With the increasing consumption level and the finishing technology of wool fabrics,

There are endless varieties.

This is not a single textile technology to achieve, but textile, chemical, polymer materials and bio engineering and other aspects of technology collection, especially in the finishing technology is the most outstanding performance.

Therefore, the finishing technology of wool fabrics and the application of various finishing agents are highly valued by people in the wool textile industry.

Traditional wool finishing can be attributed to two main categories: wet finishing and finishing.

Influenced by this traditional idea, some old manufacturers installed the rolling mill in the wet shop on the arrangement of the equipment, while the dryer was installed in the drying workshop.

Such installation arrangement is very unfavorable to the development of modern wool fabric finishing technology, and is also very harmful to the display of finishing effect, and it is prone to produce many defects.

Take soft finishing as an example, the commonly used amino modified silicone microemulsion softeners will be sent to the drying workshop after drying the liquid in the wet shop. After the stacking of the cloth, the working fluid will make the front and back fabrics feel different, and sometimes there will be soft cross gear.

At present, the finishing technology used in wool textile production mainly includes soft finishing, oil repellent, antifouling, shrinkproof, antistatic and hygienic finishing.

At present, most manufacturers choose double amino modified organosilicon microemulsion softeners and stearic amide softeners in the production of woolen fabrics.

When applied, one of the classes can be selected according to the style of the fabric.

The softeners can also be mixed in different proportions.

The former is characterized by smoothness, its emulsion particles are very fine, the particle size is about M, and the molecules can enter the fibers, so they are called softeners in fibers.

When manufacturers are producing, high concentration (0%) softeners produced by emulsion polymerization can be directly used by low molecular organosilicon monomers, and their viscosity is low and particles are finer.

The latter can give the fabric a rich and soft handle, but the fabric is less slippery than the former.

Therefore, the thin fabric with high support can be mixed with the former or both, and the higher proportion of the former is used for finishing.

Finishing process.

The working fluid is composed of AV-90 amino modified silicone microemulsion softener to g/L penetrant g/L (process) below two degrees below 40, dip two rolling (rolling rate 70% or so) - drying.

The softening agent for stearic acid amide emulsion can be calculated according to its 8% concentration, and the working liquid is finished with the softener 0 ~ 0g/L.

Oil repellent antifouling finish.

As a high-grade woollen fabric, it is popular with consumers for its oil repellent and antifouling properties.

The finishing of this kind of fabric is to use a fluorine compound to form a thin film on the surface of the fiber, change the surface tension of the fabric, and make the water and oil hard to wet on the surface, so as to achieve the effect of oil repellent and water repellent.

These auxiliaries can also reduce the surface specific resistance of the fabric and have certain antistatic and dustproof effects.

At present, there are FC-50 and FC-50 produced by M company in the domestic market, which are suitable for high-grade woolen fabrics.

The finishing agent FC-50 and FC-50 are both emulsion of fluorides, and the ambient temperature can not be higher than 50 degrees when stored.

It should be noted that wetting agents, silicone softeners and defoamers must not be added to the working fluids.

The working fluid is composed of FC-50: for example, the total wool or wool polyester fabric is 0 to mL/L acetic acid, and the pH value is about 55 FC-5040 to 60g/L.

Two dip two roll and then dry.

The wool and polyester fabric can also be finished after heat treatment of the working fluid.
