Cloth introduction:
1.Yarn-dyed cloth: the structure of the silk thread is well
shaped. The appearance is similar to 5 pieces of satin and 8 pieces of satin.
The density is better than 5 pieces of satin and 8 pieces of satin.
Specifications are generally 75 * 100D, 75 * 150D and so on. The raw material
of tinted cloth: it can be cotton, blended or polyester, or pure chemical
fiber, which is formed by the different organization of the fabric. The product
that lubricious ding bu makes popularity is wide, glossiness drape feels good,
feel soft. Elastic colored butyl cloth "adopts polyester FDY dayou light
50D*DTY75D+ spandex 40D as the raw material, and USES satin weave weave in the
jet loom. Because the warp thread adopts dayou light silk, the cloth surface
has charm, and occupies a place in the recent fabric market with the advantages
of lightness, smoothness, elasticity, comfort and luster. Polyester low-elastic
silk is the raw material, the fabric structure USES satin plain grain to change
the texture, woven on the air jet loom, grey cloth and then after desizing,
pre-shrinking, softness and other treatment, the fabric permeability is
particularly good, and feel soft and smooth, fabric width is 150cm. Design and
color d set comfort, modern sense, artistic sense in one of the new fabrics
2. Non-woven fabrics: They are directional or random fibers. They
are a new generation of environmental protection materials. They are
moisture-proof, breathable, flexible, light, non-combustion-supporting, easy to
decompose, non-toxic, non-irritating and colorful.
3. Twill: various twill fabrics are used to make the surface of
the fabric show oblique lines formed by warp or weft floating lines. Twill is a
medium thickness denim, there are two kinds of thick, fine (20-40 pieces), are
using 2/1 left twill organization, texture than plain cloth slightly thick
soft, front lines clear.
4, rabbit wool: rabbit wool fiber scales are relatively smooth.
Soft sex, hygroscopicity, do not have a ball, also be rabbit flannelette
material underwear rises in recent years one of main reasons. Rabbit hair
belongs to amino acid protein fiber, which is similar to the composition and
structure of human skin, has a good skin-friendly feeling, and has the function
of maintaining animal life.
5, crystal super soft wool surface to be more delicate, feel
better. High density between fibers, strong three-dimensional sense of hair,
beautiful appearance, compared with the original super soft, glossiness is
higher, feel more soft and thick, fine texture, environmental protection and so
on.
6, wool fabrics have a velveteen, velvet, velvet, cluster
flannelette, polyester silk fabrics flannelette flannelette, knitted fabrics,
cotton fabrics flannelette velvet, velvet fabrics, warp knitted fabrics
flannelette (new varieties, with 50 d polyester yarn and polyester FDY such
DTY75D / 36 f/strong mesh as raw material, using the knitting chain structure,
fabrics successively after scouring desizing, finalize the design, dyeing,
softening, stenter stereotypes, such as deep processing), hole ring
flannelette, super soft plush cloth (the latest varieties), short plush cloth
(the latest varieties)
First, the diameter of the retractable roll is constantly changing due to the roll of the printing press during winding and unwinding. When the unwinding torque is constant, the diameter decreases, the tension increases, and the winding is the opposite. If the winding-up torque is constant, the tension will decrease as the winding diameter increases. This is determined by the inherent characteristics of the press and is a major factor in the change in tension in the aluminum foil.
Second, the uneven quality of aluminum foil material affects the change of tension, such as the fluctuation of the elastic modulus of the material, the change of the material thickness along the length of the width, the eccentricity of the material volume, and the level of heating will give the whole machine Tension brings a subtle influence.
Thirdly, the printing press will cause sudden changes in the tension of the entire machine during the process of refueling or feeding. The higher the operating speed of the equipment is, the greater the interference is, and the tension changes greatly and the stability is poor. In order to restore the tension to the original stable state, the tension should be automatically and randomly adjusted according to the tension of the tape tension. During overprinting, the printed web must have moderate tension when it is being conveyed. When the tension is too small, the web at the detection position is prone to jitter, which affects the precision of overprinting, the tension must be constant, in order to ensure a constant instantaneous speed, and require the main motor to run. To be stable, you can't be fast or slow, and you can't shake, otherwise it will affect the accuracy of overprinting. 
Our company is equipped with advanced production machines and
