The difference between pp non-woven fabric and non-woven non-woven fabric
by:Sunshine2020-10-01
Pp non-woven fabric and non-woven non-woven, pp refers to the raw material is pp, non-woven fabric spunlace nonwoven said the production process, these two kinds of non-woven fabrics mainly from technological process has the difference, specific to the cloth is not fundamentally different.
Now explain in detail the PP non-woven fabric: non-woven fabric of the exact name should be nonwoven fabric, nonwoven or call.
Because it is a kind of don't need to be formed by spinning weaving fabric, just short textile fiber or filament for directional or random supporting columns, form a fiber network structure, and then by adopting the method of mechanical, hot glue or chemical reinforcement.
Pp non-woven fabric and the characteristics of the difference between spunlace non-woven non-woven non-woven fabric breaks through the traditional principle of textile and a short process flow, production speed, high output, low cost, wide application, raw material source, etc.
The purpose of non-woven fabric, its main purpose can be roughly divided into: (
1)
Medical and health with non-woven fabric: gown, protective clothing, XiaoDuBao cloth, mask, diapers, civil cloth, wiping cloth, wet towel, magic towel, soft towel roll, beauty products, sanitary napkin, sanitary pads and disposable sanitary articles, etc. ;
(
2)
Home decorative non-woven: stick wall cloth, table cloth, bed sheet, bedspread, etc;
(
3)
Clothing with non-woven fabric: cotton lining, fusible interlining, flocculus, finalize the design, all kinds of synthetic leather base cloth, etc.
(
4)
Non-woven fabric used in industry;
Filtering materials, insulation materials, cement bags, nonwoven fabric and coated fabric, etc. ;
(
5)
Agricultural use non-woven fabric: crop protection cloth, seedlings, irrigation cloth, insulation curtain, etc. ;
(
6)
Other non-woven fabric: space cotton insulation, heat preservation material, linoleum, cigarette filter, bags, tea bags, etc.
The kinds of non-woven non-woven fabric according to the different production process can be divided into: 1, spunlace nonwoven: high-pressure micro flow injection to a layer or multilayer fiber net, make the fiber tangled together, so that the fabric is strengthened and have a certain strength.
String 5 2, heat-sealing non-woven: refers to the fabric with fibrous or powder hot melt adhesive reinforcement materials, fabric after heating molten cooling reinforcement into cloth.
The non-woven fabric: 3, pulp flow into a network and can be called air-laid paper, dry process of paper making non-woven fabrics.
It is the airflow into network technology will open pine wood pulp fiber board into a single fiber state, and then use airflow method makes fiber aggregation in the shade on this network, web reinforcement into cloth.
4, wet nonwoven: fiber raw material is placed in a water medium opening into single fiber, at the same time make different fiber ingredients, made from fiber suspension slurry, suspension slurry to the network, fiber under wet condition into a network to reinforce into cloth.
5, spun-bonded non-woven fabric: is in polymer has been after extrusion, stretching to form a continuous filament, filament laid into the net, fiber network by self bonding, hot glue, chemical bonding or mechanical reinforcement method, make fabric non-woven fabrics.
6, melt-blown non-woven, its technological process: polymer feeding -
-
-
Melt extrusion -
-
-
Fiber formation -
-
-
Fiber cooling -
-
-
Into the net -
-
-
Reinforcement into cloth.
7, acupuncture non-woven fabric: is a kind of dry non-woven fabric, needle-punched nonwoven fabric is using the puncture of pricker, fluffy fabric reinforcement into cloth.
8, stitch-bonded nonwoven cloth, is a kind of dry non-woven fabrics, sewing lawmakers is the use of warp knitted coil structure on fabric, yarn, textile materials (
Such as plastic sheets, plastic thin metal foil, etc. )
Or their combination for reinforcement to made from non-woven fabric.
