Special treatment for synthetic textiles
Synthetic
textiles have some special treatments like below-

Heat setting
Heat the setting is a very important step for finishing synthetic textiles. It is used
to describe any thermal process in the textile industry, it is usually in a
steam environment or in a dry thermal environment. The effects of the process
give fiber, yarn, or fabric dimensional stability and often give other
desirable qualities such as higher volume, shrinkage resistance, or temperature
resistance. The heat setting is also used to improve the properties for
subsequent processes. The heat-setting of synthetic fabrics eliminates internal
tension inside the fiber, is generated during production, and the new state can
be stabilized through rapid cooling. This heat setting fixes the fabric in a
relaxed state and thus avoids subsequent shrinkage or creasing of the fabric.
The processing of products makes it possible to use higher temperatures for
setting without considering the sublimation properties of the dyes and also has
a favorable effect on the dyeing behavior and the running properties of the
fabric. The post-setting, on the other hand, can be combined with some other
activities such as thermal dyeing or polyester optical illumination. The
post-setting as the final finish is effective in achieving high dimensional
stability with the desired handle. An important part of textile finishing is
heat-setting.
Stiffening and filling process
Stiffening
agents are the kind of fabric finishing chemicals that are needed to improve
the textile hand to feel the hardness, cleanliness, and crease resistance.
These are most commonly used in the textile industry to provide the desired
properties during raw yarn processing. A harsh effect is recommended on certain
polyamide and polyester materials (e.g., petticoats, collar inner lining),
which can be achieved by finely coating the polymer in the form of a fine film
by reducing the mutual independence of the structural elements of the fabric.
Hydrophilic finishing process
Hydrophilic
finishing processes compensate for the loss of moisture and water absorption in
synthetic fiber materials, which become uncomfortable with skin contact. Certain
products based on modified polyamides reduce water viscosity to make the fabric
more pleasant so that it spreads over a larger area and evaporates more easily.
Anti-peeling finishing process
The anti-peeling finishing process removes peeling, an unpleasant phenomenon
associated with cut yarn fabrics, especially when they contain synthetics.
Synthetic textiles are more easily brought to the fabric page due to their
smooth surface and round cross-section and higher tensile strength and abrasion
resistance. This also happens with knitted "picks": by rubbing the
individual fibers the loops of yarn work on the outer surface and the garment
is caught above any point or rough object. Knitting is sensitive to these
effects due to the open loom and huge yarn.
Anti-static finishing process
The anti-static finishing process prevents dust from clinging to the fabric.
Anti-static effective chemicals are essentially chemically inert and require
thermal or heat treatment for fixing in polyester fabrics. Polythene agents
have been shown to be useful but they will not affect the pigment consistency
on the fiber, lest they frequently disrupt the viscosity. In general, thermosol
anti-static agents also have good soil release action, which lasts as an
anti-static effect. Anti-static finishes can also be of the polyamide type, it
is curable at moderate temperatures.
Non-Slip Finishing Process
Non-slip
finishing processes give the filaments a rougher surface. Synthetic warp and
weft threads in loose knitted fabrics are particularly at risk of slipping
because they have a smooth surface when the fabric structure is disrupted and
the look is no longer attractive. Silica gel scattering or silicic acid
colloidal solutions are used in conjunction with latex polymer or acrylate
scattering to simultaneously improve peeling or scattering resistance to get a
more lasting effect. These polymer finishes are able to provide a soft and
smooth handle on synthetic fabrics without contaminating them with water.
Flame Retardant finish
The
term flame retardants are served in different groups of chemicals that are added
to plastics and textiles, and materials produced as surface finishing and
coating. Flame retardants are activated by the presence of an ignition source
and are intended to prevent or slow the subsequent development of ignition by a
variety of different physical and chemical methods. They can be added as
copolymers during the polymerization process, or later added to the polymer in
any molding or extrusion process, or as a topical finish, especially in
textiles. Flame retardants are commonly
added to industrial and consumer products to meet flammability standards for
building products such as furniture, textiles, electronics, and insulation.
