In the past, the relatively large role played in production was manual, but manual operation not only resulted in low work efficiency, but also relatively high costs. With the development of technology, more and more new equipment came out, and the appearance of mechanical equipment Many problems were solved manually, and the production line was born under this background. Below we give you an analysis of the advantages of using a spunbond nonwoven production line.
Generally not. The melting point of conventional polypropylene non-woven fabric is 160 ~ 170 ℃; and that of polyester non-woven fabric is about 260 ℃.However, there is a material that is made of acrylic fiber, viscose fiber or asphalt fiber by needle punching method, after oxidation treatment and carbonization treatment and then graphitization, the carbon felt is made of high temperature resistance up to 3000 ℃, The coefficient of thermal expansion is less than (2 ~ 5) * 10-6 / ℃, the strength is 3 times that of aluminum alloy, and the weight is only 1/5 of that of steel. This material is used in aerospace, spacecraft, rocket nose cone, tail exhaust In the protective layer inside the tube and the large scale integrated circuit.
(Also known as nonwoven bags, English: Nonwoven bags) is a green product, also known as non-woven environmental protection bags, non-woven shopping bags, non-woven portable bags. The main component of non-woven fabric is PP (polypropylene), the fabric has a variety of colors for customers to choose, bag size, thickness, style can be specified by the customer. Can withstand a variety of printing processes such as silk screen hot stamping, logos and text can also be printed according to customer requirements. At the same time, the product is tough and durable, beautiful in appearance, good in breathability, reusable, washable, screen-printed advertising, long use period of labels, suitable for any company, any industry as advertising and gifts.
The exact name of non-woven fabric should be non-woven fabric, or non-woven fabric. Because it is a fabric formed without spinning and weaving, it is just oriented or randomly braided short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many raw material sources. Its main uses can be roughly divided into:
The textile industry is more popular in today's society, and it has helped the rapid development of fields including textile processing, clothing design, and clothing sales. This all depends on the modern people's pursuit of beauty. How to make a beautiful piece of clothing? This naturally requires the use of a lot of processing equipment. Non-woven equipment is a more commonly used and practical tool for textile products. This kind of equipment usually needs some Maintenance and maintenance measures to ensure its normal operation when used, the specific requirements are as follows:
In the 1940s, architects in Europe and the United States discovered that traditional waterproof materials (such as PE membranes, asphalt waterproofing membranes, etc.), due to their airtightness, caused the water vapor in the building envelope to be closed for a long time, which caused roofing and walls Moisture occurs and mold grows, and indoor air quality and human living environment are seriously threatened. Water vapor intrusion seriously affects the performance of building insulation materials, thereby increasing building energy consumption. Water vapor condensation also accelerates the aging of building materials and affects the durability of buildings.
After years of precipitation and hardening, Huiyu has formed its own unique innovation, competition, cooperation, integrity, dedication
