what is non woven?
Non-woven fabrics do not have latitude and longitude lines, cutting
and sewing are very convenient, and light and easy to shape, loved by
hand-lovers.
Because it is a kind of fabric that does not need spinning woven fabric,
but the textile short fibers or filaments are oriented or randomly
arranged to form a fiber network structure, and then reinforced by
mechanical, thermal adhesive or chemical methods.
Instead of being intertwined and braided together by a single yarn, the
fibers are directly bonded together by physical means, so when you get
the sticky name in your clothes, you will find that It is impossible to
extract the root of a root. Non-woven fabrics break through the
traditional textile principles, and have the characteristics of short
process flow, fast production rate, high output, low cost, wide use, and
many raw material sources.
The relationship between nonwovens and spunbonds
Spunbonded fabrics are non-woven fabrics. There are many production
processes for the manufacture of nonwovens, of which spunbonding is one
of the non-woven production processes.
what is non woven?
(Including spunbonding, meltblowing, hot rolling, and hydroentanglement,
most of the nonwovens currently produced in the market are spunbonded)
Non-woven fabrics based on the composition, there are polyester,
polypropylene, nylon, spandex, acrylic, etc.; different components will
have different styles of non-woven fabrics. Spunbonded fabrics are
usually referred to as polyester spunbonds and polypropylene spunbonds.
The styles of these two fabrics are very close and can only be
determined by high temperature testing.
Non-woven fabric is a kind of non-woven fabric. It directly uses polymer
chips, short fibers or filaments to wind the fibers through airflow or
mechanical web, and then it is hydro-entangled, needle-punched, or
hot-rolled, and finally finished. Non-woven cloth formed. The new fiber
products with a soft, breathable and planar structure have the advantage
of not producing lint, strong, durable, silky and soft, but also a kind
of reinforcing material, but also a cottony feel, compared with cotton,
non-woven Cloth bag is easy to form and cheap.
advantage:
1. Lightweight: polypropylene resin as the main raw material, the proportion is only 0.9, only cotton
Non-woven finished products

Three-fifths of it is bulky and feels good.
2. Soft: Consisting of fine fibers (2-3D) Light-point hot-melt adhesive molding. The finished product is soft and comfortable.
3. Water-repellent, air-permeable: Polypropylene chips do not absorb
water, water content is zero, finished product is water-repellent,
composed of 100% fiber with porosity, good air permeability, easy to
keep the fabric dry and easy to wash.
4. Non-toxic, non-irritant: The product is manufactured in accordance
with FDA food grade raw materials, free of other chemical components,
stable in performance, non-toxic, no odor, and does not irritate the
skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically
inert substance, not insects, and it can isolate bacteria and insects
in the presence of liquid erosion; antibacterial, alkaline corrosion,
the finished product will not affect the strength due to erosion.
6. Antibacterial. The product is water-removing, not moldy, and can isolate the bacteria and insects in the liquid.
7. Good physical properties. The direct spinning of polypropylene
spinning is made by heat-bonding. The strength of the product is better
than that of ordinary staple fiber products. The strength is
non-directional and the strength in both vertical and horizontal
directions is similar.
8. In terms of environmental protection, most of the raw materials used
are polypropylene, and the plastic bag is made of polyethylene. Although
the two materials have similar names, their chemical structures are
quite different. The chemical molecular structure of polyethylene is
very stable and extremely difficult to degrade. Therefore, the plastic
bag needs 300 years to be decomposed; while the chemical structure of
polypropylene is not strong, the molecular chain can be easily broken
and can be effectively degraded. , And in the non-toxic form into the
next environmental cycle, a non-woven shopping bag can be completely
decomposed within 90 days. Moreover, non-woven shopping bags can be
reused more than 10 times, and the environmental pollution after
disposal is only 10% of the plastic bags.
Disadvantages:what is non woven?
1) Poor strength and durability compared to woven fabrics.
2) It cannot be cleaned like other cloths.
3) The fibers are arranged in a certain direction, so it is easy to
split from a right angle. Therefore, improvements in production methods
are mainly aimed at preventing the improvement of division.
