Moisture absorption rate is low Polyester Filter Silk Screen Mesh
1. high strength. The short fiber strength is 2.6-5.7 cN/dtex, and
the high strength fiber is 5.6 polyester 8.0 cN/dtex. Due to its
lower hygroscopicity, its wet strength and dry strength are
essentially the same. Impact strength is 4 times higher than nylon
and 20 times higher than viscose.
2. Good elasticity. The elasticity is close to the wool. When the
elongation is 5% to 6%, the wrinkle resistance is higher than other
fibers, ie, the fabric does not wrinkle, and the dimensional
stability is good. The elastic modulus is 22 to 141 cN/dtex, 2 to 3
times higher than nylon. Polyester fabrics have high strength and
elastic recovery, so they are strong and durable.
3. Heat-resistant polyester is made by melt-spinning, and the
formed fiber can be heated and melted again. It belongs to
thermoplastic fiber. The melting point of polyester is relatively
high, and its specific heat capacity and thermal conductivity are
small. Therefore, the heat resistance and heat insulation of
polyester fiber are higher. It is better in synthetic fibers.
4. Polyester has a smooth surface and closely packed internal
molecules. Polyester is the best heat-resistant fabric in synthetic
fabrics. It has thermoplastic properties and can be made into
pleated skirts with long lasting pleats. At the same time,
polyester fabrics have poor resistance to melting, and holes are
easily formed in the presence of soot and Mars. Therefore, you
should try to avoid contact with cigarette butts and sparks while
wearing them.
5. Good wear resistance. The wear resistance is second only to
nylon with good abrasion resistance.
6. Lightfastness is good. Lightfastness is second only to acrylic.
Polyester fabrics have better lightfastness, and their light
resistance is better than that of acrylic fabrics. In particular,
the light resistance behind the glass is very good, almost
comparable to acrylic.
7. preservative. Resistant to bleaches, oxidants, hydrocarbons,
ketones, petroleum products and inorganic acids. Resistant to
alkali, not afraid of mildew, but hot alkali can make it decompose.
There is also strong acid and alkali resistance, UV resistance
8. Dyeing is poor, but the color fastness is good, not easy to
fade. Because there is no specific dye group on the polyester
molecular chain and the polarity is small, the dyeing is more
difficult, the dyeability is poor, and the dye molecules are not
easy to enter the fiber.
9. Fabrics made of ordinary polyester filaments have excellent
strength, smoothness, easy washing and drying, etc., but they have
a hard hand feeling, poor tactility, soft luster, poor air
permeability and poor hygroscopicity. Other disadvantages. If
compared with silk fabrics, the gap is even greater, so first
simulating silk on the wire structure can eliminate the
disadvantages of poor performance. 10. Poor hygroscopicity, wearing
a hot feeling, but also easy to bring static electricity, dirt,
affecting the appearance and comfort. However, it is easy to dry
after washing, and the wet strength is almost not reduced, no
deformation, good washability and wearability
