About non woven fabrics vs. non woven fabrics

The kind you are talking about is a kind of non-woven fabric, called PP spunbond non-woven fabric, also called polypropylene spunbond non-woven fabric, which can be used as a storage bag. The dot recess is controlled by the production process, called hot rolling, and there are patterns on the roller, which can be square dots and sesame dots.

Spunbond non-woven fabric: After the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a web, and the web is then turned into a non-woven fabric by self-bonding, thermal bonding, chemical bonding or mechanical reinforcement.

Features High strength, good high temperature resistance (can be used for a long time in 150 environments), aging resistance, ultraviolet resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, mothproof, non-toxic.

Main uses: The main products of spunbond non-woven fabrics are polypropylene polyester (long fiber, short fiber), and the most common and commonly used one is non-woven bags.

applications such as non-woven packaging, and it is also easily recognizable, because the rolling point of spunbond non-woven fabric is diamond-shaped.

At the application level, it can also be used for flower wrapping cloth, luggage cloth, etc., which is wear-resistant, firm and feels good, etc., making it the best choice for making this kind of product.

Non-woven fabric is not the same as non-woven fabric. Non-woven fabrics are mainly used to make environmentally friendly bags, and non-woven fabrics are used to make handmade.

Moreover, there are many kinds of non-woven fabrics, and non-woven fabrics are only one of the non-woven fabrics, which is naturally different.

Just like cotton, there are many types of cotton cloth - cotton or fiber ......(This is my personal opinion).

There is still a difference.

Non-woven fabrics are mainly used to make environmentally friendly bags, and non-woven fabrics are used to make handmade.

There are also many kinds of non-woven fabrics in 1653, and non-woven fabrics are only one of the non-woven fabrics.

In fact, there is no difference between non-woven fabrics and non-woven fabrics, they are just two different names. It is to specify the direction or random arrangement of some fibers, and then through various methods such as interweaving, they are combined with each other to make a thin piece of cloth. In general, it is customary to use Cantonese.

Friends will say that the weaver is buried in the year, and the standard Mandarin name is non-woven fabric. The use of non-woven fabrics is also relatively extensive, and it has also been widely used in the medical field on a large scale.

Non-woven fabrics, Qingcao non-woven liquid fabrics are all cloth materials. () Honor Hu shirt.

a.That's right. b.Mistake.

Correct Answer: a

The use of non-woven fabrics is related to laundry products such as clothing interlinings, shoulder pads, warm wadding, children's clothing, children's shoe sole leather, artificial deerskin, synthetic leather, carpets, bed photos, bed sheets, curtains, etc. Non-woven fabrics cannot be used as fabrics for clothing, but can only be used as accessories. Non-woven materials are wide, the processing process is short, the output is high, the variety is many, the cost is low, and the application range is wide.

It is known as the third field after weaving and knitting. The main uses of nonwovens in clothing are as follows:

1. Hot-melt adhesive lining.

A hot-melt adhesive lining is an interlining made by evenly coating a hot-melt adhesive on the base fabric. It can be bonded with the fabric under certain heating and pressure conditions, so as to play the role of reinforcement and shape preservation, referred to as adhesive lining. Non-woven adhesive lining accounts for more than 60% of the adhesive lining used in clothing.

There are several types of hot melt adhesives.

1) Polyethylene high-density polyethylene is characterized by high adhesive strength, good washing resistance, hard hand feel, and slightly higher melting point (128-134), which requires a press and ironing machine, which is not suitable for small garment factories and processing points that use irons. Low-density polyethylene can be used as an iron, but the quality is low, the pressure is easy to seep, the water resistance is poor, and it is not suitable for shirt collar lining.

2) Polyamides have excellent adhesion and excellent dry cleaning and washing resistance, but they must be bonded with a press ironing machine.

3) Polyester has a low melting point, a slightly worse dry cleaning and washing resistance, and is highly adapted, and its application is limited.

4) The dosage of ethylene-vinyl acetate is the largest, accounting for more than 60%. The melting point is low and the iron is available. The comprehensive performance is higher than that of low-density polyethylene and lower than that of polyamide.

2. Warm flocculents.

Thermal wadding refers to the padding material used for cold-proof clothing, ski shirts, bedding, sleeping bags, pillows and other cold-proof and warm products.

1) Spray rubber cotton, also known as spray rubber wadding, spray resin adhesive on the fiber web, and dry and cure. The commonly used material is polyester.

2) Hot-melt wadding cotton, commonly known as shaped cotton, with polyester and acrylic as the main material.

3) Spray cotton composite treatment Spray cotton is combined with thin non-woven fabric or non-woven canvas adhesive lining to make composite wadding. This type of product has a high cost and is generally used for high-end clothing and leather clothing.

4) Metal-coated thin-lint composite wadding is commonly known as metal cotton, space surface, and space cotton. It is composed of five layers: polyester elastic fleece floc, non-woven fabric, polyethylene film, aluminum-titanium alloy reflective layer, and surface floc. The insulation effect is remarkable in particularly cold or particularly hot conditions.
