Fabric color fastness index

First, the color fastness to friction
1, dry erase: with a piece of cloth and dyed cloth friction, see the white fabric dyeing to determine the level of color fastness
2, wet rub: Method Ibid (with a damp cloth).
Usually fabric color fastness in three to four; color depth color light fastness must reach four.

Second, staining fastness:
Colored cloth stained white cloth washed or rubbed to see the degree of staining to determine the level of color fastness. (Light and dark color, sensitive color, in order to avoid the problem of color transfer we must require the color fastness of the fabric is better, which is commonly referred to as the six kinds of fiber fixation.
The so-called six kinds of fiber means: Wool, Acrylic, Polyester, Nylon, Cotton, Acetate,
Color depth and light color fastness must reach four to five or more. The inquiry must indicate the need to report six kinds of fiber fixation, rather than later added.

Third, the light fastness: (related to the clothes will soon become old)
(That is, fabric alkalinity) to imitate the sun, the fabric in the sunlight irradiation to a certain standard time to see the degree of fading to determine the level of light fastness. Especially fluorescent color fabrics should pay attention to light fastness. At the same time, the level of the sun also has a direct impact on the fabric UV protection.

Fourth, test pressure:
The correct way to measure water pressure, glue side up, cloth side down.
Many fabricators will make fake water pressure in order to save costs. Fake water pressure is usually made of AC glue, and then coated with bright glue. The performance is as follows: the glue surface is very bright and the water pressure difference before and after hand rubbing is large (for example, Fell to 500MM-600MM, a good pressure before and after the general difference of around 200MM), tape stick is not strong and so on.
Therefore, when talking about the price you need to ask the supplier what kind of plastic fabric backing, stressed that the plastic can not be bright, it should be matte. And our request for water pressure. And understand such as: 2000MM they painted a few times, at the same time emphasize at least 3 times after the water pressure reaches: 1200 or 1500 or 2000MM
When placing an order with the supplier to confirm what we use heat seal. Such as the use of semi-PU paste is not strong, switch to full PU paste, need to indicate the full PU and semi-PU strip the difference is how much this cost borne by them!

Five, plastic
White plastic and transparent plastic contrast: White plastic relatively speaking feel thicker, leather feel, flexibility is better, but the price is usually back to your point, suitable for thin fabrics, but also pay attention to the white glue the following points: For example Glue whiteness (not enough white plastic surface only two possibilities, one is the poor quality of the plastic, the other is the amount of plastic coated enough) caldera, and coating uneven and so on.

Sixth, the fabric has fish stench,
The fabric has the main smell of formaldehyde containing formaldehyde is not volatile clean, (formaldehyde excessive will cause some damage to human skin) If the fabric is opened, that smell a pungent fishy smell, it shows that formaldehyde Volatile clean. The fabric will pass through a drying box when it is finished with glue. There is a high-temperature exhaust mechanism in the drying box, the flavor of formaldehyde is to be discharged through this mechanism. Fabric through the drying box normal speed of 40 m / min (breathable and breathable to 30 m / min) However, the fabric factory in order to catch up, it will speed up, and some even opened to 100 m / min, so there will be High temperature is not enough, the surface has a serious wet feeling, sticky, and accompanied by fishy smell, not only that, it will cause water pressure does not meet the requirements, or by hand or wash it again after reaching zero water pressure terrible consequences . At the same time the adhesive tape adhesion is not enough, gently pull all will fall off, it will simply be a disaster!

Seven, test through the wet
Each batch of large cloth must be sent to the Provincial Commodity Inspection Bureau inspection.

Eight, tooling fabric testing (according to different guest wash temperature to reach 60 degrees to 90 degrees)
1, tear strength: warp, weft not less than 30N;
2, tensile strength: the latitude and longitude can not be less than 1200N;
3, wear resistance: spring and summer wear fabric friction to go through more than 20,000 times, winter clothing fabrics to pass: more than 40,000 times;

Xinxiang City Yulong Textile Co., Ltd. was established in 2002, over the years focused on the production of flame retardant, fluorescent-oriented variety of functional fabrics and security clothing. The company has afunctional fabric factory and protective clothing factory, as the domestic functional textile industry leader, Yu Long textile more groundbreaking integration of its fabric and clothing two factories of the advantages of resources, effort to build functional fabrics and clothing Station service center.
