Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.
PP ribbon manufactor The tensile strength after light treatment, the natural light shines on the bag webbing through the window, causing aging and reducing its strength. According to the working conditions, a lighting equipment is designed, which is equipped with representative strong light and is exposed to the light for a specified time. After lighting, pp webbing needs to be subjected to standard temperature and humidity treatment, and then to tensile test to obtain the tensile strength after lighting treatment. PP ribbon manufactor After soaking, the tensile strength of the safety belt installed in the car will absorb the moisture in the air, and sometimes it will be soaked by some liquid, so special PP ribbon Water immersion test is required. At room temperature special PP ribbon Fully immerse in distilled water with a small amount of wetting agent for a specified time, and then take out the soaked pp webbing from the water to complete the tensile test within 10 minutes. The tensile strength of soaked pp webbing was obtained.
Those who can decorate themselves can make their temperament different with cheap things, but those who do not know how to observe and learn can not make themselves outstanding with expensive gold ornaments. Sometimes they are also funny and outstanding. If words are superfluous, let's see how to decorate themselves. Some people just need a small or elastic belt to make their whole body exude personality and elegance. Just slightly change their carry on items and add a small pattern or color to make friends around look impressive. There are no pictures to support my idea, but many friends around me can confirm my opinion. Therefore, good decoration must be done with your own heart, instead of using money to buy beauty and personality.
Hygiene: It is a natural fiber, and its main component is cellulose, with a small amount of waxy substances, nitrogen and pectin. After various inspections and practices, the pure cotton ribbon has no stimulation or negative effect when contacting with the skin. It is beneficial to the human body and has good sanitary performance after being worn for a long time. Heat resistance: the heat resistance is good. When the temperature is below 110 ℃, it will only cause water evaporation on the webbing and will not damage the fiber. Therefore, the use, washing, printing and dyeing of pure cotton webbing at room temperature have no impact on the webbing, which improves the washing and wear resistance of pure cotton edging webbing.
If the weft needle is damaged, replace it or beat it with gauze; If the steel buckle is damaged, hit it with gauze or replace the steel buckle; The coir filament piece is damaged or the shutdown piece is damaged. Replace it with a new one. Causes of poor needle edge: uneven weft yarn thickness; The knitting needle is not properly laid, too long or too short; The pan head moves abnormally, sometimes tight, sometimes loose; The weft wheel is not round enough and deformed; Wear of the fixed pin of the knitting needle; Precautions: change another weft yarn; The knitting needle is longer or shorter according to the thickness of the ribbon. Generally speaking, the length of the knitting needle is just enough to remove the weft; Fix both sides of the pan head firmly, and do not let the pan head lean against the iron frame on both sides; Replace the weft wheel with a new one; Replace the fixed rod or go to processing.
Silk fabrics have high porosity, so they have good sound absorption, dust absorption and heat resistance. Therefore, in addition to making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. Due to its hygroscopicity, moisture release performance, moisture retention, air absorption and porosity, it can also adjust the indoor temperature and humidity. Silk fiber has small thermal denaturation and is relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600C, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.
