Part index of fabric quality

A friction color fastness,
1, dry wipe: with a white cloth and dyeing cloth together friction, see the white fabric dyeing degree to determine the color fastness Level 2, wet wipe: the method is the same as above (with a damp cloth).
Usually, the color fastness of fabric is from three to four, and the color fastness of deep and light color matches must reach four.
Two, fastness:
Colored cloth is stained with white cloth, washed or rubbed to see the degree of color to determine the level of color fastness. (dark, light, and sensitive, and in order to avoid color removal, we must ask for better color fastness, which is commonly referred to as the six fiber fixation.
It is six kinds of fiber refers to: wool (Wool), acrylic (Acrylic), polyester (Polyester), nylon (Nylon), cotton (Cotton), acetate (Acetate) deep and light color fastness must reach four to more than five. In the inquiry, you must indicate that you need to report six kinds of fiber fixation, rather than later.
Three, light fastness: (related to the clothes will soon become old)
(that is, the alkalinity of a fabric) imitate the sun's rays, and determine the degree of color fastness of the fabric in a certain amount of time, depending on the degree of discoloration seen under the sun. In particular, fluorescent fabrics should pay attention to the fastness of sunlight. At the same time, the level of the sun also directly affect the fabric UV protection.
Four, test pressure:
The correct way to measure water pressure is to face up and press down.
Many manufacturers in order to save the cost will be false false pressure, pressure is generally AC adhesive backing, and a bright surface glue: adhesive surface is very bright, hand rub before and after the pressure difference large (for example, from 2000MM fell to 500MM-600MM, the pressure difference before and after the good general is about 200MM), rubber mount firm etc.. Therefore, when talking about price, you need to ask suppliers of fabric with what gum base, stressed that the glue can not light, should be the fog surface. And our requirements for hydraulic pressure. And they understood as: 2000MM coated for several times, also stressed that, at least 3 times after washing water reached 1200 or 1500 or 2000MM
We need to confirm with the supplier when placing the order. Such as the use of semi PU affixed to prison, to use all PU stickers, you need to specify the full PU and semi PU stickers, the difference is how much, the cost to be borne by them!
Five, glue
Compared with the transparent glue glue: adhesive will feel relatively thick, skin feeling, elasticity is also good, but the price is usually back to your point, suitable for thin fabric, glue but also should pay attention to the following points: for example, the whiteness of the rubber surface glue (not white enough only two possibilities, one is the glue the quality is not good, the other is a glue coated enough) volcano, and uneven gluing etc..
Six, fabric fish fishy smell,
The smell of fabrics mainly for plastic contains formaldehyde did not evaporate (formaldehyde exceed the standard, it will cause some harm to the human body skin) if the fabric is opened, which smelled a pungent fishy smell, the formaldehyde not evaporate. When the glue is finished, it will go through a drying box, and there is a high temperature exhaust mechanism in the drying box. The smell of formaldehyde is to be discharged through this mechanism. Fabric after normal speed drying box is 40 m / min (air permeability is 30 meters / minute) but the fabric factory in order to catch the goods, will speed up, some even up to 100 m / min, it will produce high temperature is not enough, the rubber surface has a serious sense of wet, sticky, and accompanied by a fishy smell. Not only that, it will cause the water pressure is not up to the requirements, or hand washing or scooping up after zero pressure over the terrible consequences. At the same time, the sticking force of the paste is not enough, and a slight pull will fall off completely, which will be a disaster!
