What is viscose and what are the characteristics of viscose?

Viscose fiber is the full name of viscose and viscose.

It is further divided into viscose filament and viscose staple fiber. Viscose - also known as rayon, ice, viscose filament. In recent years, there has been a new high-grade variety of viscose called tencel and bamboo fiber.

Viscose is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber is the most in line with the physiological requirements of the human body, and has the characteristics of smooth coolness, breathability, antistatic, and gorgeous dyeing.

Viscose fibers are regenerated cellulose fibers. It is made of natural cellulose as raw material, made into soluble cellulose xanate by alkalizing, aging, yellowing and other processes, and then dissolved in dilute lye to make viscose, which is made by wet spinning. Using different raw materials and spinning processes, ordinary viscose fibers, high wet modulus viscose fibers and high-strength viscose fibers can be obtained respectively.

Ordinary viscose fiber has general physical, mechanical and chemical properties, and is divided into cotton type, wool type and filament type, commonly known as rayon, artificial wool and rayon. High wet modulus viscose fibers have a high degree of polymerization, strength and wet modulus. This fiber can bear the load per unit linear density in the wet state, and the wet elongation under this load does not exceed 15%, mainly rich and strong fibers.

High-strength viscose fibers have high strength and fatigue resistance. See.

Viscose is viscose fiber.

Viscose, a major variety of man-made fibers. Alkaline cellulose is made from natural cellulose alkaline, and then reacts with carbon disulfide to form cellulose xanthate, which is dissolved in a dilute lye solution to obtain a viscous solution called viscose, which is formed into viscose fiber after wet spinning and a series of treatment processes.

1. Viscose has good hygroscopicity (it is the strongest hygroscopicity in ordinary chemical fibers), breathability, and good sense of tranquility when wearing;

2. The viscose fabric is smooth and soft, silky, smooth to the touch, has excellent dyeability, and is not easy to fade;

3. It is not easy to generate static electricity and has good spinning performance. Staple fibers can be pure spinning, can also be blended with other textile fibers, the fabric is soft, smooth, breathable, comfortable to wear, bright color after dyeing, and good lead fastness of color wild eggplant. It is suitable for making underwear, outerwear and various decorative items.

Filament weaving is light and thin, and can be used as clothing for quilt and decorative fabrics.

Shortcoming. 1. Viscose fiber feels heavy, has poor elasticity and is easy to wrinkle, and is not crisp;

2. It is not washable, wear-resistant, easy to fluff, poor dimensional stability, and high shrinkage rate;

3. It is not resistant to alkali or acid.

Viscose fiber is the full name of viscose, which is obtained from natural wood cellulose and remodeling fiber molecules from "wood" as a raw material.

The hygroscopicity of viscose fiber meets the physiological requirements of the human body, and has the characteristics of smooth coolness, breathability, antistatic, anti-ultraviolet, gorgeous color and good dyeing fastness. It has the essence of cotton, the quality of silk. It is an authentic plant fiber, which comes from nature but is superior to nature.

At present, it is widely used in all kinds of underwear, textiles, clothing, non-woven and other fields.

What is Adhesive? What are the types of adhesives?

What is Adhesive? Adhesive is actually a kind of adhesive, which is basically a thick liquid state, which can tightly bond two different materials or objects of the same material together. There are many different types of adhesives in the market, and these adhesives are non-metallic materials.

With the development of science and technology, it has been widely used in people's daily life and industry or other fields. So what are the types of adhesives? Let's follow us to find out.

What are the types of adhesives?

There are many types of adhesives on the market, such as silicone adhesives, epoxy adhesives, rubber adhesives, and construction adhesives. Each type of adhesive is very practical and targeted. In the following, we will introduce several adhesive applications to users.

1. Silicone adhesive.

Mail silicone adhesive is a kind of sealing adhesive in the adhesive, it has strong cold resistance, heat resistance, aging resistance, waterproof and moisture resistance, non-toxic and harmless and other excellent characteristics compared with other adhesives. In recent years, the development of silicone adhesives in China is getting bigger and bigger, and the development is getting better and better. The application is also becoming more and more extensive.

2. Adhesives for construction.

Construction adhesive is literally an adhesive that is used specifically in construction. With the continuous development of our current and dry economy, people's living standards are improving day by day, and the demand for housing construction is also increasing. This has led to an increase in the production of construction adhesives.

This adhesive is mainly used in the engineering decoration of buildings and the application of sealing or structural engineering.

3. Packaging adhesive.

Packaging adhesive is mainly an adhesive used in factory packaging to bond product labels. The materials of these products are different, including metal, plastic and wood. That's why we usually use their specific adhesives for this.

4. Epoxy resin adhesive.

Epoxy adhesive has a wide range of applications, can bond a wide variety of materials, and it can bond metal materials. Therefore, it is widely used in various industries such as automobiles, electronics, etc. It can also be used in daily life, non-toxic and harmless, relatively safe and healthy.

Summary: There are many types of adhesives on the market, and the objects that can be bonded by each adhesive are relatively large, and each adhesive will have a special one that is more suitable.

That's all it brings to you: What is an adhesive? What are the types of adhesives? All of it.

Adhesive is a substance with good adhesive properties. Through adhesion and cohesion, the surface is bonded to the surface and plays the role of connecting objects. A class of organic or inorganic, natural or synthetic substances that can connect the same or more homogeneous or heterogeneous parts together and have sufficient strength after curing, collectively referred to as adhesives or adhesives, adhesives, and are customarily referred to as glue.

Classification 1, according to the application method can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc.

2. According to the application object, it can be divided into structural, non-constructive or special glue. Structural adhesives include: epoxy resins, polyurethanes, silicones, polyimides and other thermosetting adhesives; polyacrylate, polymethacrylate, methanol and other thermoplastic adhesives; There are also modified multi-component adhesives such as phenolic-epoxy type.

3. According to the curing form, it can be divided into four types: solvent volatile type, emulsion type, reaction type and hot melt type.

4. Synthetic chemists often like to classify adhesives according to the chemical composition of the adhesive.

5. According to the main components, it is divided into organic and inorganic.

6. According to the classification of appearance, it can be divided into three categories: liquid, paste and solid.

7. Classification by component: single component, double component, reactive type.
