  • What is polypropylene fabric used for?
    Sep 24, 2020

    Being warm, non-hygroscopic, stable, wrinkle and transformation resisted, wear-resisted, flexible and comfortable, polypropylene (PP) is the lightest fiber in the several common chemical fibers. As a new green product whicn featured by recoverable,reusable and easly degradable (compared wth 100year degradation term of plastic products, PP only uses 3 to 5 years), polypropylene can reduce oil exploitation and the consumpton of non-renewable resources as to reduce the pollution made by garbage disposal, so PP is a new favorite of the age instead of PE/PVC and other common plastics. Polypropylene is a kind of highly pliable chemical fiber which can greatly improve the elasticity of the webbbing, bags and suitcases, meanwhile, with the advanced producing technique of Sanhong the products are much more pliable and wear-resisted.

  • What is polyester yarn
    Sep 05, 2020

    There are many types of polyester fiber fabrics. In addition to pure polyester fabrics, there are many products mixed with various textile fibers, which make up for the shortcomings of pure polyester fabrics and exert better wear performance. At present, polyester fabrics are developing in the direction of synthetic fibers such as wool, silk, linen, and deerskin. Polyester imitation silk fabric is a polyester fabric with a silk-like appearance woven from polyester filaments or short natural fiber yarn with a round and profiled cross-section. It has the advantages of non-ironing and is very popular with consumers. Common varieties are: polyester silk, polyester crepe, polyester satin, polyester georgette, polyester interwoven silk and so on. These varieties have the elegant drape, smoothness, softness, and pleasing of silk fabrics. At the same time, they also have the stiffness, wear resistance, easy washing and non-ironing of polyester fabrics. The disadvantage is that these fabrics have poor moisture absorption and breathability and are not too cool to wear. In order to overcome this shortcoming, more new polyester fabrics have come out, such as high moisture absorption polyester fabrics. https://www.sanhongfibre.com/900d-high-tenacity-polypropylene-yarn_p46.html

  • Polyester V.S Polypropylene
    Aug 26, 2020

    What is Polyester Polyesters are polymers formed from the condensation polymerization between a dicarboxylic acid and a diol. Polyester is a common name used to describe long-chain polymers composed of ester groups in the main chain. Polyesters are chemically composed of at least 85% by weight of an ester and a dihydric alcohol and a terephthalic acid. In other words, the reaction between carboxylic acids and alcohols which forms esters cause the formation of a polyester. Polyesters are highly useful polymers due to their important properties such as high strength, high durability, hydrophobic nature and quick drying. Polyester is useful as fibers, films, packaging material, etc. https://www.sanhongfibre.com/products What is Polypropylene Polypropylene is a thermoplastic polymer that has applications as fibers and plastics. It is made out of propylene monomer. Polypropylene softens when heated and can be remoulded into different shapes. Polypropylene is made from addition polymerization. The major application of this material is its use as a packaging material. This polymer material can be used for making containers for the microwave oven. Polypropylene does not react with water and most chemicals. Polypropylene is considered as a tough material. It is also highly resistant to electricity. So it is a good electrical insulator. Polypropylene is easy to customize. We can add dye during the manufacturing of polypropylene in order to obtain colorful polymer material. Unlike other plastics, polypropylene does not absorb water due to its hydrophobicity. Polypropylene has a light weight and is flexible as well. Both polyester and polypropylene are polymers. Polyester is formed via condensation polymerization between a dicarboxylic acid and a diol. Polypropylene is formed via addition polymerization of propylene monomers. The main difference between polyester and polypropylene is that polyesters can absorb some amount of water whereas polypropylene does not absorb water at all. We are professional exporter and manufacturer of polypropylene/polyester yarn and polypropylene/polyester webbing in china. Find great deals and get fast shipping here.

  • What is polypropylene yarn
    Aug 03, 2020

    Polypropylene yarn, which is accepted as the lightest and useful yarn used in the textile sector, is also called PP yarn. Polypropylene yarn has a hygienic structure that does not cause allergic reactions. Moisture formed by sweat and similar causes is thrown out by the breathing structure, it does not hold moisture and water and it does not contain dirt and stain. At the same time, it is in a more advantageous position than many other yarn variants in terms of conversion to nature and reusability. It is a type of yarn that can also be given high strength properties at the required ratios. It has features such as high durability and unbreakability to be gained by the applications made during manufacturing. Due to its technical characteristics, it is not only used by the narrow weaving sector as the most preferred yarn type but also used in many different fields and sectors such as home textile, sock and carpet manufacturing. https://www.sanhongfibre.com/products Advantages of Polypropylene Yarn Flexibility, low density, low thermal conductivity, low moisture absorption, compatibility with foodstuffs, minimum static electrification, superior resistance to chemicals ... Light Weight PP can reduce the weight of the bags and make the bags more portable. It is the lightest among the yarns used in the textile industry. It is a very light polymer compared to polyester and nylon from other synthetic yarns. Converted to Nature Polypropylene is the most advantageous synthetic polymer in synthetic materials such as polyester and nylon. 100% recycled and reused with the features of power saving, low-carbon and environmental friendly. No Moisture in the World PP is a water-repellent, water-repellent (hydrophobic) polymer. Therefore, their mechanical properties are not affected by changes in relative humidity. Does not Leave Color PP does not hold paint after production. The yarn is painted in the color demanded during production and the same color is obtained in each order. There is no color difference problem. Dirt and Stain PP is not suitable for dirt and stains due to its molecular structure, it breathe. The sweaty napkin allows the body to stay dry by allowing it to pass through the dress. The dust absorption of PP material is only equivalent to the wool. Not Allergy It does not contain dirt, stains and dyes as well as it has anti-bacterial properties by not containing bacteria in its body. Also anti-allergic, additional ingredients can be produced anti-bacterial.

  • The main difference between the quality standard of colored spun yarn and primary yarn
    Jun 23, 2020

    The difference between the quality assessment index and the primary color yarn: Since the color-spun yarn is different from the primary color yarn, its evaluation index should strive to reflect the overall quality of the product, and pay attention to the physical quality and post-processing performance. In addition to the single yarn breaking strength and coefficient of variation of the primary color yarn assessment, the 100 meters weight variation coefficient and the weight deviation, the uniformity variation coefficient and other quality indicators. According to the characteristics of dyed yarn and finished products, the assessment of indicators such as obvious color knots, kilometer neps, color fastness and color difference, and bobbin yarn end breaks has been added. Since the finished product of primary color yarn is processed through multiple processes, and the color light of the color-spun yarn is the color light required by the finished product, the color light and color fastness of the color-spun yarn are strictly required. The difference between the quality index level of dyed yarn and the original color yarn: Due to the dyeing process of the color spinning yarn, some indicators of the fiber have a certain decrease compared with the original color fiber, especially the varieties with a color cotton ratio of more than 50, the single yarn breaking strength and the evenness index of the yarn are lower than the original color yarn , And other quality indicators have improved to varying degrees.

  • The purpose of twisting
    Jun 23, 2020

    The twisting system is a general term for equipment that adds twist to spun yarn, silk , and chemical fiber filaments. The core equipment is various double-twisting machines. The front of the double-twisting machine is to change the package or merge multiple strands. The single yarn equipment is the supporting equipment for the double twister. Twisting is to increase the strength and abrasion resistance of the thread, reduce the fluffing or breaking of the thread, improve the fabric fastness or increase the cohesion before dyeing; make the thread have a certain shape and fancy effect, so that the fabric can obtain refractive, wrinkle, Appearance effects such as loops and knots; improve the elasticity of the silk thread, improve the anti-wrinkle ability and cool feeling of the fabric. For staple fibers, twisting is mainly to increase the strength of the yarn; twisting of the filaments can not only increase the strength of the yarn, but also produce some effect. The amount of polyester twisted yarn and the combination of the twist direction and twist of the yarn in the fabric have a great influence on the appearance and performance of the product. The indicators indicating the degree of twisting include twist, twist factor and twist direction.

  • Marine Department begins sampling inspection of container VGM declaration
    Jun 19, 2020

    The NEW rules, due to come into effect on July 1st, add to the woes of the shipping industry. Relative to multiple revenue items, the penalty should be more fearful, shipping companies like us are afraid of trouble. With the end of the so-called policy "easing period" or "flexibility period", according to the "first loosen and then tighten, first tighten and then adjust" strategy of THE INTERNATIONAL Maritime Organization (IMO) and other big ship companies, it seems that THE VGM will tighten up at present. The risk of failing to submit VGM or submitting VGM late is due to the uniform requirements of "NO VGM NO LOAD" on major ports and shipping companies, as well as high penalties for late submission, excessive weight errors and changes. From June 1, many shipping companies began to levy overweight fees. CMA European OWS charges USD150 for more than 18TONS and above (excluding the box weight). MSC dexi & North Africa renewal OVW charge USD200 for small boxes over 20TONS (including 20TONS). MSC will renew OVW in Europe in June, and charge USD100 for small boxes over 20TONS (including 20TONS). Maersk will charge USD300 for the "heavy weight error report" of containers that VGM misreported for export. To ensure the safety of container operations and transport, the Marine Department of some ports has started spot checks of container weight verification. On June 1, Yantai Zhifu Marine Department immediately launched the container weight verification inspection activity, the law enforcement personnel at the dock first carried out a detailed inspection of the weight verification information of the cargo containers. Upon inquiry, it was found that some crew members did not know enough about the new rules or the procedures were not standard enough, and the law enforcement personnel required them to make rectification promptly. If they found that the weight provided by the shipper was not in conformity with the actual weight, they should inform the maritime administrative authority in time, and the ship could not sail until the requirements were met.
