How To Distinguish Non-Woven Fabrics With Fluorescence Method?

Nowadays, with the improvement of economic level, our concept of environmental protection is also growing. Many manufacturers are also optimistic about it.

The development prospects of bags have been gradually put into this industry, but faced with this problem.

With so many nonwoven bags, how do we tell the true and false? Now, Xiaobian summarizes some methods for your reference.

To distinguish the true and false of nonwoven bags, we need to know several decisions first.

1. look at the lathe of non-woven bags.

We should know that stitching is very important in the process of non-woven bags. Cheap nonwoven bags usually only take a single line in order to save costs, and the workers with insufficient experience make the product suture not straight or even running.

2. look at the number of non-woven fabrics.

The number of grams here refers to the weight of non-woven fabric in 1 square meters, the heavier the weight of the non-woven fabric is, the thicker and stronger the natural fabric will be. The non-woven fabric bags used by ordinary enterprises are mostly applicable to the cost saving of 80 grams of non-woven fabrics. The 80 grams of non-woven fabrics can be reused for 10 times, and the handle is thinner 70 grams, which can bear 4-5 kg weight. 80 grams can bear 5-6 kg weight, and so on.

3. look at Nonwovens Technology

A good quality non-woven fabric bag is not only durable but also very good-looking, and it is very good in the hand. Most of the non-woven bags on the market are screen printing. The non-woven bags of screen printing are cheap and clear lines. Besides human factors, another important indicator is pigment. Some unscrupulous manufacturers use poor dyeing agents to cause non-woven bags to be environmentally friendly and even pungent.

Here we will introduce specific methods to detect the authenticity of non-woven bags.

Method 1: water detection method

Placing non environmental bags in water and pressing them into the bottom of the water is non-toxic and non environmental friendly. The proportion of them is small and can float out of the water.

Method two: fire detection method

Nontoxic polyethylene non environmental protection bag is flammable, the flame is blue, the upper part of yellow is burning, it is dripping like candle tears, it has paraffin taste and smoke is little, toxic PVC non environmental protection bag is not inflammable, extinguishes from fire, the flame is yellow, the bottom is green, softening can draw silk, and has the pungent smell of hydrochloric acid.

Method three: jitter detection method

Grasp the non environmental bag with one's hands, shake hard at one end, and make clear and clear.

Method four: sensory detection

Non toxic non environmental bags are milky white, plucent, or colorless, pparent, flexible, feel lubricated and have wax on the surface. Toxic non environmental bags are turbid or yellow, and feel sticky.
