The world of professional production and supply of acupuncture non-woven manufacturers, the introduction of foreign advanced technology, quality assurance, the full range, price concessions, sales ahead.


Today, Xiaobian give us a detailed description of our country of the world of high-quality acupuncture non-woven


Acupuncture non-woven fabrics are a non-woven fabrics, polyester, polypropylene raw materials manufacturing, after a number of acupuncture to be processed from the appropriate hot-rolled. According to the process, with different materials, made of hundreds of commodities.


Overview: acupuncture non-woven fabric is a dry non-woven fabric is a short fiber through the open, carding, paved a fiber network, and then the fiber network through the needle reinforcement into a cloth, thorns needles hook barbed wire, the fiber network Repeated puncture, hook with fiber reinforcement, the formation of acupuncture non-woven, non-woven non-latitude and longitude of the points, into cloth fiber messy, the latitude to the performance difference is not. Typical products: Synthetic leather fabric, acupuncture geotextile and so on.


Processing: polyester, polypropylene raw materials, the carding, combing, pre-acupuncture, the main acupuncture. The center adds the mesh cloth sandwich, and then passes through the double-channel nuclear management, the air current network acupuncture compound into the cloth, the post-press filter cloth has the three-dimensional structure, after heat setting, singeing, on the surface most chemical oil treatment, Smooth surface, uniform distribution of pores, the surface of the product from the surface of the good density, both sides of the surface smooth and good ventilation in the frame compressor on the use of proven, you can use high-strength pressure, filtration accuracy of up to 4 microns, Need to provide two kinds of raw materials of polypropylene and polyester. Practice has proved that non-woven filter cloth filter in the frame when the performance is better: the case of coal preparation plant treatment, iron and steel plant wastewater treatment. In the brewery, printing and dyeing wastewater treatment plant. Such as the use of other specifications of the filter cloth filter cake pressure will not dry, but also difficult to fall off the problem, with non-woven filter cloth, the filter press pressure to reach 10kg-12kg is quite dry, and filter open frame filter cake Will automatically fall off. Users in the choice of non-woven fabric, mainly based on air permeability, filtration accuracy, elongation, etc. to consider different thickness, quality of non-woven fabric, the product parameters, please point polyester needle felt and polypropylene needle felt, specifications varieties are Can be developed.

Acupuncture non-woven products is through a fine carding molding, a number of precision acupuncture or hot rolling from the appropriate treatment. At home and abroad in the introduction of two high-precision production line on the basis of acupuncture, the choice of high-quality fiber. Through the production process with different, and the combination of different materials, the current market circulation of hundreds of different products, including: geotextile, geomembrane, with velvet, speaker blanket, electric blanket cotton, embroidered cotton, cotton clothing, Christmas Handicrafts, the leather cloth, filter cloth for cloth.


Processing principle: the production of non-woven with acupuncture is entirely through a mechanical action, that is, the needle puncture needle puncture effect, the fluffy web reinforcement to get together and get strong [1]. The basic principle is:

Repeated puncture of the web is carried out with a barbed barbed needle of triangular cross-section (or other cross-section). As the barbs pass through the web, the web surface and localized layer fibers are forced into the web interior. Due to the friction between the fibers, the original fluffy web is compressed. When the needle is withdrawn from the web, the punctured fiber bundle leaves the barbs and remains in the web so that many of the fiber bundles entangle the web so that it can no longer return to the original fluffy condition. After a number of needling passes, a significant number of fiber bundles are pierced into the web and the fibers in the web are entangled with each other to form a needle-punched nonwoven material having a certain strength and thickness.

Acupuncture

Non-woven technology in the form of pre-thorn, the main thorn, pattern acupuncture, ring needle and tube acupuncture.




Development characteristics: Acupuncture non-woven fabrics in the proportion of non-woven production line 28 percent to 30 percent, in addition to conventional air filtration and dust control, the new application of non-woven acupuncture space is being Expansion, transportation, industrial wiping ... Any combination of non-woven process combinations or combinations of types is actually possible, which makes the characteristics of the ideal case to adapt to special, more application requirements [2].

Acupuncture non-woven products, the standard gap is large, lag and other standardization issues by the production and application of the same attention to the parties. Industrial textiles involved in health, safety, environmental protection and other fields, in accordance with the standardization law should be the development of mandatory standards, but the existing mandatory standards are less, it also affected the standard requirements of the standard is difficult to unity, the implementation of efforts have also been affected . On the one hand, the product manufacturers tend to focus on the general performance of products, the use of the drafting of the textile industry to recommend national standards or industry standards; and product users tend to focus on product engineering performance, the use of related industry norms, contradictions.

In addition, the standard system is not with international practice. In view of China's industrial textile industry centralized management is not enough, there is no close attention and specializes in international and foreign advanced industrial textiles standards bodies, the relevant standards of information collection, aggregation, analysis is not enough, resulting in the index requirements and testing methods and international standards Inconsistency.

Industrial textiles use different, with other textiles do not have the unfamiliar and complexity of the industrial textiles related to all aspects of personnel, including experts, including a test. Therefore, the industry consensus is to fully mobilize the level of industrial textiles to play the enthusiasm and role of the Association to speed up the formulation and revision of industrial textiles standards, and jointly promote the standardization of industrial textiles, scientific and standardized operation.


Difference: acupuncture non-woven fabrics, spun-laced non-woven fabrics are non-woven (also known as non-woven fabric), non-woven fabric dry / mechanical reinforcement of two. Which, as the name implies, the biggest difference between the two processes is the reinforcement of a mechanical needle is a mechanical high-pressure water needle reinforcement, the process directly to the different functions of different products.

Acupuncture non-woven fabric weight is generally higher than spunlace non-woven weight. Spunlaced non-woven raw materials more expensive, cloth is more delicate, the production process than the acupuncture clean. Health medical / health / beauty with a more extensive. Acupuncture raw materials than the spunlace wide variety, filter * / felt / geotextile and so on.

The difference between acupuncture and spunlace: Acupuncture is generally thicker, weight is generally 80 grams or more, fiber coarse, rough feel, the surface of small pinholes. Spunlaced cloth grams of common in the following 80 grams, 120-250 grams of special, but very few. Spunlace feel more delicate, vertical surface of a small strip of spunlace lines.
