��Dust-proof function;
②Soft styling makes the fabric feel soft and smooth, but pay attention to whether the fabric will slip. Water repellency and soft styling can be done at the same time to make the fabric both waterproof and soft, but the softener will affect the degree of water repellency.
③Resin setting is mainly used to fix the yarn of the fabric and make the hand feel stiff. Some resins contain formaldehyde, so pay attention to the selection; water splashing and resin setting can be done at the same time, and the resin has a promoting effect on the water-splashing agent.
④ Flame retardant styling has an auxiliary effect on the flame retardant function of the fabric. Flame retardant can also be water-repellent styling at the same time, but special attention should be paid to the selection of water-repellent agent, otherwise the flame retardant effect will be too great.
⑤ Anti-static styling makes the fabric anti-static and can be done at the same time as water-splashing styling, but it will have an impact on the water-splashing effect.
⑥ Moisture wicking and shaping allows the fabric to quickly absorb sweat, making sportswear more comfortable. It cannot be done at the same time as splashing water.
⑦ Antibacterial and deodorizing processing mainly makes fabrics have antibacterial functions and is mainly used in medical facilities.
⑧Super water-repellent styling (also called Teflon treatment): It has better waterproof and dust-proof effects than ordinary water-repellent styling, and it also has oil-proof function. Generally speaking, customers will ask for a DuPont hangtag.
7. Calendering and gluing:
A. The functions of calendering are: 1. Softening the feel; 2. Making the calendered surface of the fabric smoother, narrowing the gaps between fabric fibers to prevent lint, or enabling higher water pressure when applying glue; 3. Making the glued surface smoother Beautiful ④The calendered surface has a bright effect. B. The three elements of calendering are temperature, speed and pressure. Calendering changes the color of the fabric. C. Gluing can make the fabric waterproof, velvet-proof, windproof, etc. It can also fix the fabric, increase the look and feel, and thicken the feel, making the fabric more valuable. D. Gluing includes acrylic (also known as AC, PA), PU glue, moisture-permeable and breathable glue, which can be processed into transparent glue, white glue, silver glue, colored glue, pearlescent glue, excellent glue, etc. Corresponding raw materials can also be added to the glue to make it anti-ultraviolet, flame retardant, and anti-yellowing.
E. When applying glue, pay attention to controlling the water pressure, feel (thickness, softness and hardness), glue application uniformity, glue peeling strength, water washing resistance (whitening), whiteness, etc. Also pay attention to the rubber particles, glue marks, and whether it is dry on the rubber surface. Pay attention to the effect of applying waterstop strips (PVC strips/PU strips) on the rubber surface.
8. Laminating PVC: Pay attention to the thickness and feel of the lamination, the peel strength of the lamination, the quality of the adhesive surface, etc.
9. Other processing: dry PU (release paper), composite, PU leather, etc.
10. Washing: Some cotton, N/C, and T/C also need to go through a washing process. There are three types of washing: ordinary washing, soft washing, and enzyme washing (to remove floating hair on the surface of cotton cloth).
11. Finished product inspection: Inspect the quality of finished products, classify them into grades, and package them for shipment. Generally, inspection records and discrepancy sheets must be affixed. If you have any questions, please report them to the salesperson promptly so that you can communicate with customers in a timely manner.
Chapter 3 Quality Focus of Fabrics
1. Width: Generally refers to the effective width, that is, the width within the pinhole, or the effective width after gluing.
2. Longitude and latitude density: When there are strict requirements, be sure to measure the latitude and longitude density.
3. Weft camber: Generally, the weft camber of plaid fabrics should not be greater than 3%, and the weft camber of plain fabrics should not be greater than 5%.
4. Shrinkage: The shrinkage in the warp and weft directions of the finished product after washing.
5. Water repellency: ISO is measured in degrees (50 degrees bad to 100 degrees good), or AATCC levels (1 bad to 5 good). AATCC level 3 is equivalent to ISO’s 80 degrees.
6. Color fastness: This is a very important indicator, which includes washing fastness (fastness to color fading and staining), water fastness (fastness to color fading and staining), and sun fastness (fastness to color fading and staining). ), rubbing fastness (fading, staining), perspiration fastness (fading, staining), sublimation fastness, dye migration, etc., measured by level (level 1 is poor to level 5 is good).
7. Strength: tensile strength, tear strength, bursting strength (kg/cm2).
8. Water pressure resistance: The strength (waterproof degree) of the cloth against water pressure, such as 2000mm/H2O (millimeters of water column). The higher the value, the better the waterproof performance.
9. Moisture permeability: The unit is g/M2*Day, which indicates the mass of water passing through 1 square meter of fabric in 24 hours under a certain temperature and humidity.
10. Oil splashing degree: a test indicator used for Teflon processed fabrics, divided into 5 levels (level 1 is poor to level 5 is good).
11. In addition, there are tests on flame retardant performance, antistatic, anti-ultraviolet and other characteristics. These require professional institutions to test, so I will not go into details here.
