Analysis of plastic non-woven fabric of non-woven fabric

First, the definition of non-woven fabric

Nonwoven, also known as non-woven fabric, non-woven fabric.

A sheet, web or batt made by orienting or randomly arranging fibers by friction, cohesion or bonding or a combination of these methods. It does not include paper as well as woven fabrics, knitted fabrics, tufted fabrics, stitchbonded fabrics with stitching yarns, and wet-reduced felts (whether or not such products are needle-reinforced).

The fibers may be natural or chemically processed, and may be short fibers, filaments or fibers formed in situ.

Note: 1. The difference between wet and non-woven paper is that the non-woven fabric should meet one of the following conditions:

a, the fiber composition of the length to diameter ratio of more than 300 fibers (excluding chemically cooked plant fibers) accounted for more than 50% of the mass;

b, the fiber composition of the length to diameter ratio of more than 300 fibers (excluding chemically cooked plant fibers) accounted for more than 30% of the mass, and its density is less than 0.4 / cm3.

2. Viscose fibers are not considered to be chemically cooked plant fibers.

Second, fiber raw materials

There are many types of fiber materials suitable for non-woven fabrics, mainly natural fibers and chemical fibers. In order to produce nonwovens of different properties, uses and styles, high performance specialty fibers and functionalized, differentiated fibers can also be used.

(1) Natural fibers: such as cotton, wool, hemp, silk, etc.;

(2) Chemical fiber: such as viscose fiber, polyester, nylon, polypropylene, acrylic, vinylon, etc.;

(3) Differentiated fibers and high-performance fibers; such as: low-melting thermal bonding fibers (ES fiber, modified polypropylene, copolyamide, copolyester, etc.);

Microfiber (denier than 0.3dtex);

Three-dimensional crimped hollow fiber;

Colored fiber

High performance fiber (carbon fiber, aramid, polyphenylene sulfide, polyether ketone, etc.);

Water-soluble fiber (water-soluble polyvinyl alcohol fiber, hydroxymethyl cellulose fiber, etc.)

(4) Properties of main chemical fibers and special fibers used in nonwoven fabrics (slightly omitted)

Third, non-woven fabric classification

There are many classification methods for non-woven fabrics, which can be processed according to the non-woven section: the method of forming the web and the classification of the product.
