In order to distinguish the types of cloth first try to understand the basic knowledge of filter cloth.
One, classification
1, according to the properties of the material can be divided into cloth, polyester, polypropylene, nylon, vinylon, cotton cloth, new materials etc..
2, according to the textile way into two kinds.
(1) weaving fabric. Including polyester, polypropylene, nylon, vinylon cotton, etc.. There are several ways of woven cloth cloth, plain weave, twill, satin, double cloth etc..
(2) nonwovens. Including non-woven fabric, soil fabric, filter mat, etc.. Is acupuncture, water, spunbond weave fabric.
3, the silk cloth is also divided into three types, long fiber monofilament, multifilament, staple fiber. (including polyester staple Series in large chemical fiber, small chemical fiber)
Two, performance
Performance polyester polyamide polyamide fiber Lun Lun Lun
Good acid resistance and good not acid
Alkali resistance of alkali resistant good strong alkali resistance
The conductivity is quite good and good.
18%-45% 30%-40% of elongation at break was greater than that of polyester 12%-25%
The back is good and good than the polyester.
The wear resistance is good and good.
The temperature of the heat resistance of 130 is 90 and the shrinkage of 100 is 170.
The soft spot 230 for -240 140 and 200 for -150
The melting point 255 -265 210 and -170 220 for -215 165
Three, application:
Chemical industry: food industry, metallurgical industry, non-metallic minerals: pharmaceutical industry, environmental protection engineering, automotive industry
Four, product
The cloth products, hundreds of thousands, not one one lists. The application of polypropylene polyester, the most widely used. We use the common columns to get a familiar.
(a) weaving cloth
1, polyester fiber filter cloth
Long fiber polyester cloth, 60-8 (130) 60-10 (240) 60-9 (260) 60-7 (621) 611625
Polyester staple fiber cloth, 120-7 (5926) 120-12 (734) 120-13 (745) 120-14 (747)
120-15(758) 120-16(3927) 858
120-15 (758) 120-16 (3927) 858
2, acrylic fiber cloth
Polypropylene staple fiber cloth: 4212
Polypropylene long fiber filter cloth: 521, 527, 534, 750 (AB), 750 (A), 750 (B),
522、108(B)、108(C)、850。
108, 522 (B), 108 (C), 850.
3, nylon cloth
407、301、663、601
301, 407, 663, 601
4, vinylon cloth
295-1A、295-102、295-104、295-1
295-1A, 295-102, 295-1, 295-104
5, cotton cloth
Material, cotton 21 yarn, 10 yarn, 16 yarn, 3 x 44 x 55 x 67 x 66 x 78 x 9 x 10 1O x 1112 x 1216 x 19 variety of specifications.
6, the new high efficiency filter
New efficient filter is mainly used in air filtration and dust removal, smooth surface, good peeling property, high stability
In a variety of monofilament (commonly known as the heddle) as raw materials, polyester, nylon, polypropylene is divided into several categories.
PE：3415 3232 7033
Class PE: 341532327033
PA：2322 2325 2327 2304 5718
Class PA: 5718 2322232523272304
PP：3127 3128 3135 5722 5744 4518 3509 6022 12870
Class PP: 5744451835096022 12870 3127312831355722
(two) Nonwovens
7, non-woven fabric
Several early effect, in effect, efficient non-woven fabrics, according to the material mainly in polyester, polypropylene. Polyester, polypropylene raw materials manufacturing, acupuncture, combing, cloth center machine weaving sandwich, double nuclear airflow into network acupuncture combined into a cloth, after the filter press cloth with a three-dimensional structure, the heat setting, after singeing, on the surface of the oil chemical agent with a processing, the appearance of the filter cloth smooth, pore distribution is uniform, look from the surface density of the product is good, on both sides of the surface finish and breathable.
8, filter felt.
Surface of the hot-rolled and singeing or coating finishing, surface smooth. Divided by the materials mainly are polyester filter felt, polypropylene fiber filter felt, glass fiber filter felt, MetaMax resistant high temperature filter felt, fluorine Mae resistant high temperature filter felt, PS filter felt, P84 resistant high temperature filter felt. According to the function, there are mainly anti - temperature filter felt, anti - static filter mat, easy - cleaning filter mat, anti - oil filter mat, filter mat, plastic filter mat, etc..
9, the soil work cloth
Widely used in building, engineering, bridges, roads.
Five, the next key about filter identification method. In fact, many sites have some introduction, but emphasis on theory, what the microscope observation, what fiber density determination method, are unrealistic. We do cloth business, it is necessary to determine the type of him in 1 minutes, so a little practical, to share with you.
The differential filter, we must first understand the main technical indexes of cloth. The main has the density, the thickness, the weight, the permeability, the breaking strength, etc.. The utility has the density, the thickness and the weight and the air permeability.
1, first see. (cloth color), high gloss white fiber cloth. The small fiber cloth, dark gray, and some filtering felt such as Mexes Nobel, the color yellow. (cloth gloss) long fiber filter cloth, the surface is smooth, glossy, staple fiber cloth surface with hair. (cloth lines) and such as plain, twill, these lines, can also help you determine the type. Because some of the specifications of different lines, specifications will be different.
2, and then touch. (softness) which spun like 208729 like a plush cloth
