2. Chemical performance test
Chemical performance analysis: PH content, formaldehyde content, lead content, azo dye test, heavy metal content test, water absorption, moisture content, odor, mercerizing effect of cotton, hot pressing, dry heat, storage sublimation, acid spot, alkali Spots, water spots, phenolic yellowing, etc.
3. Ecological Textile Control Project
Banned azo dyes, carcinogenic dyes, allergenic dyes, extractable heavy metals, phenols, organochlorobenzenes and chlorine, free formaldehyde, organotin compounds, banned phthalate plasticizers, hexavalent chromium, nickel release , total lead, total cadmium, pH, color fastness, etc.
The fabrics we purchase mainly include various chemical fiber fleece (flannel, coral fleece, peach fleece, suede, sunshine fabric)
1. Dimensional change related tests
Dimensional stability of machine washing, dimensional stability of hand washing, dimensional stability of dry cleaning, dimensional stability of steam.
2. Color fastness
Color fastness to soaping (sample), color fastness to rubbing, color fastness to chlorine water, color fastness to non-chlorine bleach, color fastness to dry cleaning, color fastness to actual washing (garments, fabrics), color fastness to perspiration Color fastness to water, color fastness to light, color fastness to sea water, color fastness to saliva.
3. Sunlight material flame retardant testing, light transmittance testing.
We mainly purchase TPR particles, TPE particles, PVC particles, rubber particles, etc.
1. Plastic melt index meter Determines the flow properties of plastic particles during processing.
2.plastic moisture content test, density test.
3. Plastic particles are injected into standard test strips, and physical properties such as tensile, impact, Vicat softening point, and surface hardness are tested.
4. Appearance inspection: the reference color of plastic particles or the color of dyed plastic particles.
We mainly purchase window decoration Accessorie
1. Packaging
The packaging method should be able to effectively protect the product from damage, moisture, etc. The materials have marks such as product name, quantity, date of manufacture, material number and inspection label.
2. Appearance
Appearance requirements of internal structural parts: the surface should be flat and even, free of oxidation rust, water stains, burrs, bumps, defects, cracks,defects affecting use such as scratches, deformation, bending displacement, bumps, etc. The surface of the coating and plating layer is smooth and shiny, uniform, and there is no defects such as blistering, falling off, and burning that affect the use.
The protective film is intact, without scratches, damages, etc. The screen printing text is clear, without sagging, disconnection, blurring, etc. The content and position of the screen printing should meet the design requirements.
3. Size
The size is confirmed by the vernier caliper whether the diameter, length, width, thickness, etc. are compound requirements.
4. Strength
Whether the requirements can be compounded after destructive test and load-bearing test.
1. For the finished towels, the company's self-inspection mainly confirms that there is no excess floating hair, thread ends, whether the washing label, woven label and sewing meet the requirements, whether the color is consistent, whether the light transmittance meets the requirements, whether there is peculiar smell, and whether the size meets the requirements.
2. For the self-inspection of floor mat products, we mainly check the pattern and pattern of the product, test the adhesion of tufting, measure the size, measure the thickness, measure the weight of multiple floor mats, and measure the ground Visual inspection of the flatness of the material at the bottom of the pad.
3. After the production of roller shutter products is completed, it will be placed on a special testing table to test the use of the product to detect the smoothness of various functions. And observe the appearance to ensure that there is no defect, measure the size to ensure that it meets the customer's requirements, and check the accessories to ensure that there is no missing.
The customer can arrange for personnel to come to the door for random inspection, or there is a self-inspection list of the products we provide.
If the customer needs to provide a standard test report for some product characteristics of the product, we can cooperate with a large third-party testing agency or a testing agency designated by the customer for testing. This part of the cost needs to be negotiated.
