Part of the quality indicators of the fabric

First, the color fastness
1, dry wipe: with a piece of white cloth and dyeing cloth with friction, see the degree of white fabric dyeing to determine the level of color fastness 2, wet wipe: the same method (with wet cloth). In the case of
Usually fabric color fastness in three to four; dark color color fastness must reach four. In the case of
Second, the color fastness:
Colored cloth stained with white cloth washed or rubbed, see the degree of staining to determine the level of color fastness. (Dark color, sensitive color, in order to avoid the problem of color shift we must require the fabric color fastness is better, that is commonly referred to as six kinds of fiber fixing.
The so-called six kinds of fiber refers to: wool (Wool), acrylic (Acrylic), polyester (Polyester), nylon (Nylon), cotton (Cotton), Acetate (Acetate) deep, light color color fastness must be achieved Four to five or more. At the time of inquiry, it must be shown that six fibers need to be colored, not later. In the case of
Third, the sun fastness: (related to whether the clothes will soon become old)
(That is, the basicity of the fabric) to imitate the sun, the fabric in the sun under the exposure of a certain standard time to see the degree of fading to determine the level of sun color fastness. Especially the fluorescent color of the fabric should pay attention to light fastness. At the same time, the sun level also directly affects the fabric of UV protection. In the case of
Fourth, test water pressure:
The correct method of measuring water pressure, glue face up, cloth down. In the case of
Many cloth factory in order to save costs will be false water pressure, false water pressure with AC primer, and then use bright plastic, the performance is: plastic surface is very bright, hand rub before and after the water pressure difference (such as from 2000MM all of a sudden Fell to 500MM-600MM, good pressure before and after the general difference of about 200MM), stickers are not strong and so on. So when asked about the price of suppliers to ask what kind of fabric primer, stressed that glue can not be bright, should be matte. And our requirements for water pressure. And understand such as: 2000MM they painted a few times, and stressed that at least 3 times after the water pressure to reach: 1200 or 1500 or 2000MM
When ordering, we need to confirm with the supplier what kind of stickers we heat seal. Such as the use of semi-PU paste is not strong, switch to the whole PU paste, need to specify the total PU and semi-PU paste the difference is how much, the cost to be borne by them! In the case of
Five, on the plastic
White plastic and transparent plastic contrast: white plastic is relatively thick feel, skin feeling, flexibility is also better point, but the price is usually back to your point, apply to thin fabrics, but also pay attention to the following white plastic: Plastic whiteness (glue is not enough white only two possible, one is the quality of plastic is not good, the other is the amount of glue is not enough) caldera, and uneven coating and so on. In the case of
Six, the fabric has fish stench,
The smell of the fabric is mainly manifested in the plastic containing formaldehyde is not volatile and clean, (formaldehyde over the standard will cause some damage to the human skin) If the fabric is opened, that smell a pungent fishy smell, it shows formaldehyde Volatile clean. The fabric will go through the end of a drying box, drying box there is a high temperature exhaust mechanism, the taste of formaldehyde is to be discharged through this body. The normal speed of the fabric through the oven is 40 m / min (30 m / min for breathable and moisture permeable). However, the fabric factory will speed up the rush, and some will even open to 100 m / min. High temperature is not enough, glue a serious moist feeling, sticky, and accompanied by fishy stench, not only that, but also cause the water pressure can not meet the requirements, or hand or water again after the water pressure to achieve the terrible consequences The At the same time stickers of the adhesive is not enough, gently pull all will fall off, it will be a disaster!
