The application of molecular sieves in the textile industry is mainly based on their high porosity, large specific surface area and selective adsorption characteristics. They can effectively control humidity, separate gases, adsorb harmful substances or solvents, thereby improving the quality of textiles, optimizing production processes and meeting environmental protection requirements.
Molecular sieve in Textile Industry
Drying & Moisture-Proofing of Textiles
Molecular sieve desiccant has high selective adsorption and can selectively adsorb moisture in the environment during the storage and transportation of textile raw materials and finished products, maintain a low humidity environment, prevent textiles from mold, fiber hydrolysis or accumulation of static electricity. For example, 3A molecular sieves have a strong affinity for water, and their static water adsorption value is greater than 21%. Compared with silica gel, zeolite molecular sieves still maintain high adsorption capacity at high temperatures, can be regenerated repeatedly, and reduce consumption costs.
Air Purification
Various odors may be generated during the textile production process, such as formaldehyde, hydrogen sulfide, ammonia and other molecules. Zeolite adsorbent can adsorb odor molecules in the air, keep the workshop air fresh, and improve the working environment. For example, 13X molecular sieve beads can be loaded on the fiber surface or blended in non-woven fabrics, and effectively remove odors and filter harmful gases in the production process through physical adsorption.
ges Separation & inertization treatment
In the production process of flame-retardant fibers, high-purity nitrogen is required as a protective gas to prevent high-temperature oxidation. At the same time, in the packaging process of medical textiles, nitrogen is also needed to inhibit the growth and reproduction of microorganisms such as bacteria and molds, keep textiles clean and hygienic, and extend their service life. For example, carbon molecular sieves are used to separate oxygen and nitrogen in the air, and the nitrogen production capacity is large and the nitrogen recovery rate is high. Nitrogen is enriched by pressure swing adsorption(PSA) technology, and its purity is as high as 99.999%.
Products Description
Molecular sieve is a kind of aluminosilicate microporous crystals, which have uniform pore size and large specific surface area, good thermal stability, strong adsorption performance, high strength and long service life. Zeolite desiccants have different selective adsorption effects according to the size and shape of molecules, that is, they only adsorb molecules smaller than the caliber of the molecular sieve. For small polar molecules and unsaturated molecules, it has selective adsorption performance. The greater the polarity and the higher the unsaturation, the stronger its selective adsorption performance and strong water absorption.
other applications
Molecular sieve is widely used in petroleum, chemical, electronics, medicine, environmental protection, gas separation, air purification, metallurgy and other industries.
