  Normally, we measure the thickness of PP woven fabric in GSM. In addition, it also refers to "Denier", which is also a measurement indicator, so how do we convert the two? First of all, let's see what's GSM and Denier mean.  1. What is GSM of pp woven material? GSM means grams per square meter.   2. What is Denier? Denier means fiber grams per 9000m, it is a unit of measurement that is used to determine the fiber thickness of individual threads or filaments used in the creation of textiles and fabrics. Fabrics with a high denier count tend to be thick, sturdy, and durable. Fabrics with a low denier count tend to be sheer, soft, and silky. Then, let's do the calculation upon an actual case,  We take a roll of polypropylene tape (yarn) from the extruding production line, width 2.54mm, length 100m, and weight 8grams.  Denier means yarn grams per 9000m, So, Denier=8/100*9000=720D Note:- Tape(Yarn) width is not included in calculating Denier. As again it means...

लूम ऑपरेटर के लिए सुझाव v अपनी मशीनों को एक निष्चित अवधि पर साफ करते रहे। यह जर्रूर देखे कि , रिड रिंग के ट्रैक में टेप के टूटे हुए टुकड़े धूल अधिक मात्रा में चिपके हुए तो नहीं हैं । क्योंकि अधिक स्पीड होने के कारण मशीन के चलते हुए स्तिथि में उड़ कर टेप तोडते रहते हैं। v यह निष्चित करे कि क्रील पर सभी धागों के साथ ड्राप वायर लगा है या नही , यदि नही तोह धागों के साथ ड्राप वायर अवश्य लगायें। v धागों के साथ लगे अतिरिक्त ड्राप वायर हटा दें। ऐसा करने से भ्रम की स्तिथि पैदा नही होगी और ड्राप वायर गिरते ही पता लग जायेगा कि ये किस धागे का ड्राप वायर है। अतिरिक्त ड्राप वायर धागों में असमान्य टेंशन बढ़ाते है। जिनसे इनके टूटने की स्थिति बनती है। v ड्राप वायर हमेशा सीधा डाले , आड़ा या तिरछा नही। v ड्राप वायर सीधा डालें उल्टा नही क्योंकि उल्टे ड्राप वायर धागों का टेंशन बढ़ाते है। v एक ही वजन के ड्राप वायर का इस्तेमाल करे ताकि सामान्य टेंशन सभी धागों पर हो। v टेप के टुकड़े या सफाई में निकले धागों को बैग या उपलब्ध डबे में डाले ताकि धागे गाइड रोल्स में न फसे। v गाइड रोल्स में ...

Specifications of polypropylene Polypropylene (PP) is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Polypropylene is normally tough and flexible, and has good resistance to fatigue. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids. Basic knowledge of polypropylene Polypropylene (PP) is a thermoplastic resin polymerization system of propylene monomer. In accordance with the spatial location of the polypropylene molecular-CH3, can be divided into isotac...

Corona Treatment   Watt-Density = Power /(area x time)  US Units: W/(ft 2/minute)  [KW setting x 1000] / [Line Speed (ft/min) x width (ft)]  Example:   Treater output = 3.0 kW; line speed = 450 fpm; Treater width = 5 ft  The watt-density is: (3.0 x1000)/(450 x 5) = 1.7 W/(ft 2/min) Important:  You must determine optimum watt-density for each film and for each set of running conditions.  Some starting suggestions:  BOPP films: 3.0 – 4.0 WD  OPET films: 1.5 – 2.0 WD  BON films: 0.5 – 1.5 WD  (metric units are factor of 10 higher) Why do I need corona treating and how does it work? Corona treating increases the surface energy of plastic films, foils and paper to improve wettability and adhesion of inks, coatings and adhesives. Treating works best when a substrate is treated at the time of extrusion and in-line prior to converting. Corona treating increases quality and productivity through improved print quality, fas...
