I've been invited to judge the packet competition several times. In the written test, I always like to ask, 'How long is the validity period of sterile items in non-woven packaging?' Teachers can usually answer that WS 310.2-2009 stipulates that it is half a year. However, I noticed that there is a wording in the original specification that 'the validity period should be 6 months'. There are not many words for 'Yi'. We know that the wording of WS 310 is very strict. There are three levels of 'should-2009).
GB/T 19633 is mentioned here, the name of this specification is 'Packaging of terminally sterilized medical devicesSome teachers will ask, what do the letters in front of these standards mean? ISO is an international standard, GB is the initials of the word 'National StandardAnother teacher asked what the T in GB/T means. This is the first letter of the pinyin word for 'push' in 'recommendation'.
Many teachers use the indicator 'gram weight' when judging the pros and cons of non-woven fabrics. I feel that the greater the gram weight per square meter, the thicker the non-woven fabric, and the better the antibacterial effect. We talked about so many specifications just now. Are there any regulations on the 'gram weight' of medical non-woven packaging materials? Is there a minimum value? To be precise, the concept of 'minimum grammage' does not exist (I will explain it later), only chapter 4.2.1.2 of DIN EN ISO536 stipulates that the grammage fluctuation of each batch of non-woven fabrics must not exceed 5% of the declared value . That is, the declared gram weight of 50g, the actual gram weight of the non-woven fabric shall not be lower than 47.5g (-5%) nor higher than 52.5g (+5%).
Why not specify a minimum gram weight? This is because non-woven fabrics are a very large category, and there are many process methods covered below, and it is meaningless to simply compare the weight. When it's cold, we pull out an old padded jacket and a down jacket. Will we put on the heavy old padded jacket just after weighing it? Different process principles naturally vary greatly in thermal insulation performance, which can be based on weight alone. So having said that, considering the properties of non-woven fabrics should not be simply weighed. No matter how thick the spunbond nonwoven is, its performance is by no means comparable to that of the spunbond-meltblown-spunbond (SMS) nonwoven.

Introduction:
When it comes to fabrics and materials, there are various types that serve different purposes. Nonwovens, also known as non-woven fabrics, have gained popularity due to their versatility and wide range of uses. However, questions may arise regarding whether certain materials, such as paper, can be classified as nonwovens. In this article, we will explore the characteristics and properties of paper to determine whether it can be considered a nonwoven fabric.
Nonwoven fabrics are a type of textile material that is produced by bonding or interlocking fibers together, rather than weaving or knitting them. They are made directly from fibers or filaments, which are randomly laid or aligned to create a web-like structure. These fabrics are not woven or knitted in the traditional sense, making them different from most textiles. Nonwovens are manufactured through various processes, including mechanical, chemical, or thermal methods.
Nonwovens have gained popularity over the years due to their unique properties. They are often favored for their low cost, durability, flexibility, and ease of production. These fabrics are widely used in various industries such as healthcare, automotive, construction, and filtration. Nonwoven applications range from disposable products like diapers and wipes to geotextiles and medical protective clothing.
Paper is a material that is most commonly associated with writing, printing, and packaging. It is made from cellulose fibers derived from plants, primarily wood pulp. The fibers are usually beaten mechanically or chemically to form a pulp, which is then mixed with water and flattened into sheets. Papermaking involves a series of processes, including pulping, forming, pressing, and drying.
When it comes to categorizing paper, it is typically classified as a nonwoven in the context of nonwoven textiles. This is because paper shares similarities with nonwoven fabrics in terms of its manufacturing process and fiber arrangement. Like nonwovens, paper is made by bonding fibers together, albeit through a different process. Furthermore, both nonwovens and paper can be produced using natural or synthetic fibers.
1. Fiber Arrangement: Both paper and nonwoven fabrics have a random fiber arrangement, which imparts them with certain properties. The fibers in paper are entangled or bonded together during the manufacturing process, resulting in a cohesive structure. This randomness allows for increased porosity and absorbency in both paper and nonwovens.
2. Bonding Methods: Nonwoven fabrics are bonded through various methods, including thermal bonding, chemical bonding, and mechanical bonding. Papermaking also involves bonding the fibers together using mechanical pressure, heat, and chemical bonding agents. These bonding methods play a crucial role in determining the strength, softness, and durability of both paper and nonwoven fabrics.
3. Applications: Nonwovens are widely used in applications where properties like breathability, fluid absorption, and filtration are required. Similarly, paper is often used for these purposes, making it suitable for applications like packaging, towels, tissues, and filters. Paper shares many of the functional characteristics associated with nonwovens, although it may not possess the same level of versatility.
While paper and nonwovens share certain similarities, there are also distinctive differences that set them apart. These differences arise from variations in the manufacturing process, raw materials used, and final properties obtained.
1. Fiber Length: Nonwovens can be made from fibers of various lengths, ranging from short staple fibers to continuous filament fibers. In contrast, paper is predominantly made from short staple fibers. The longer fiber length in nonwovens contributes to their strength, whereas short staple fibers in paper make it more suitable for writing, printing, and packaging.
2. Manufacturing Process: Nonwovens often involve specialized machinery and processes designed specifically for their production. On the other hand, papermaking is a well-established industry with distinct equipment and techniques. The process of making nonwovens typically requires higher energy inputs compared to papermaking, which influences the cost and environmental impact associated with each material.
3. Final Properties: While both paper and nonwovens possess unique characteristics, their final properties differ. Nonwovens exhibit a wider range of properties, including high strength, abrasion resistance, liquid repellency, and flame retardancy, depending on the specific fibers and bonding methods used. Paper, on the other hand, is more commonly associated with properties like printability, surface texture, and foldability.
In conclusion, while paper shares similarities with nonwovens in terms of the manufacturing process and fiber arrangement, it is not typically categorized as a nonwoven fabric. Paper and nonwovens differ in terms of fiber length, manufacturing processes, and final properties. Nonwovens offer greater versatility and a wider range of applications due to their unique characteristics. Despite these distinctions, it is important to recognize the significant contributions that both paper and nonwoven fabrics make in various industries and daily life. Whether it is writing on paper or utilizing nonwoven products, these materials continue to play crucial roles in our modern world.
