Products represented by the KM750 series are formed into a stable mesh structure through high-density weaving. This process mostly uses 80-120g/m2 gram of fiber weight, and the warp and weft yarns adopt a 1:1 balance configuration, and the finished product has excellent mechanical strength.</p></li><li><p>The knitting process is based on loop-forming structure weaving, and the yarn cross-linking is achieved through a single/double-sided knitting machine. Typical products use 60-100g/㎡ gram of fiber, and the unique coil structure gives the material 15-25% elastic deformation ability. The two materials can be intuitively distinguished through simple tensile testing: woven fabric can only extend 3-5%, while knitted fabric can reach more than 20%.</p></li><li><p>Comparison of physical performance parameters 1. Structural characteristics The surface density of <a href="https://www.wipestar.com/products/850.html" target="_self"><strong>woven dust-free cloth</strong></a> can reach 300-500 pieces/square centimeter, and the pore diameter is controlled in the range of 5-10μm, which complies with the ISO Class 5 clean room standards. Its planar structure is particularly suitable for blocking suspended particles above 0.3 μm.</p></li><li><p>The typical porosity of knitted dust-free cloth is 35-45%, and the fiber gap forms a three-dimensional adsorption space. The electrostatically treated microfiber knitted fabric can capture efficiency of 0.1μm particles up to 98.5%, which is outstanding in the field of optical component cleaning.</p></li><li><p>Durability parameters wear resistance test shows that the woven fabric only loses 5% of its mass after 5,000 Martingale frictions, while the loss rate of knitted fabric reaches 12% under the same conditions. In terms of temperature resistance, all-nylon woven fabrics can withstand high temperature environments of 200℃, and the recommended use temperature of polyester blended knitted fabrics shall not exceed 150℃.</p></li><li><p>Industrial application decision model 1. Recommended application scenarios for surface treatment scenarios for woven dust-free cloth: – Removal of residual glue for engine parts in automobile manufacturing (contact pressure &gt; 3N/cm²) – Removal of flux after welding of PCB board (wiping frequency &gt; 50 times/hour) – Grinding and polishing of metal processing parts (surface roughness Ra&gt;0.8μm)</p></li><li><p>Precision cleaning requirements are preferred for <a href="https://www.wipestar.com/products-wipe-papers/" target="_self" title="knitted dust-free cloth"><strong>knitted dust-free cloth</strong></a> working conditions including: – Free particle collection in wafer production environment – Adsorption of biological pollutants in the assembly area of medical equipment – Dust capture in the LCD panel process (cleanness requirements are ISO Class 3 or above)</p></li><li><p>The memorandum of selection technology suggests that woven fabrics are regarded as &quot;industrial armor&quot; and are suitable for working conditions where mechanical strength is preferred; while knitted fabrics are like &quot;NATO sponges&quot; and are specially designed to solve the needs of precision adsorption. For clean environments below 10,000, the economy and durability of woven fabrics are given priority; in clean rooms of 100 to 100, anti-static treatment knitted microfiber products are recommended.
&nbsp;In the cleaning process in the field of precision manufacturing, the choice of dust-free cloth directly affects product yield. Taking semiconductor wafer wipe as an example, the knitted dust-free cloth made of microfibers shows the advantages of 0.3-0.5dtex (1dtex = 1 g/10,000 meters) due to its unique coil interlocking structure. This microfiber can effectively capture submicron particles. Compared with the warp and weft interwoven structure of traditional woven dust-free cloth, the three-dimensional structure formed by the knitting process can improve the liquid absorption efficiency by more than 30%.</p></li></ol><p><br/></p><p>In the optical component cleaning scenario, the actual data of an international lens manufacturer shows that when using knitted dust-free cloth to treat mirror fingerprint pollution, the number of residual particles on the surface is controlled within 5 pieces/cm², which is better than the 15 pieces/cm² of woven products. This is due to the elastic deformation characteristics of the knitted structure, its contact area increases by about 40% compared to the rigid woven fabric, which is similar to the principle of memory foam to fit the skin and can evenly disperse the wipe pressure.</p><p><br/></p><p>From the analysis of material characteristics, the warp-weft weaving structure of woven dust-free cloth has higher mechanical strength and is suitable for PCB board drilling and dust removal and other processes that require physical polishing. The coil interlocking structure of knitting non-woven is better at handling curved surface cleaning, accounting for 68% of the application in the medical device field, especially in the cleaning process of endoscopic lenses, which exceeds 90%.</p>
