Fabric Crimp (বাংলায়)

আসসালামু আলাইকুম (আল্লাহর শান্তি ও দয়া আপনাদের সবার উপর বর্ষিত হোক) আজকের ভিডিওতে ফেব্রিকের ক্রিম্প নিয়ে বিস্তারিত আলোচনা করা হল। চেষ্টা করেছি সংক্ষিপ্ত সময়ের মধ্যে Fabric Crimp এর যাবতীয় বিষয় আলোচনা করতে। আলোচ্যসুচীঃ What is crimp Formula to measure crimp Crimp Testing Mathematical Problem Impact of Crimp on Textiles Crimp: When warp and weft yarns interlace in fabric they follow a wavy path. Crimp percentage is a measure of this waviness in yarns. Crimp (C) =(𝒍−𝒑)/𝒑 × 100% Where, l = Straightened thread length P = Distance between the end of the thread while in cloth It can be in both warp and weft direction Warp Crimp (C1) =(𝒍−𝒑)/𝒑 × 100% = ((𝟑𝟔.𝟕 𝒄𝒎−𝟑𝟓 𝒄𝒎))/(𝟑𝟓 𝒄𝒎)× 100% = 4.86% Problem 1: To produce 5000m of fabric with 3% warp crimp how many yards of yarn will be required? Problem 2: Let you have 24”×20 cm dimension fabric sample. Calculate the warp crimp and weft crimp when length of yarn is 62 cm and 21.1 cm respectively Problem 3: To produce 1500 yard of woven fabric having specification "114 × 90" /"20 × 18" "×" 56” and warp & weft crimp is 4% & 5% respectively, how many cones of weft yarn will you require if weight of each cone is 1.5 lb. Impacts on Textiles: Thickness Weft and Warp yarn consumption Resistance to abrasion Shrinkage Fabric Costing Let off and Take up roller speed variation ধন্যবাদ। *Answer:* (1) 5150 m (2) 1.70% and 5.5% (3) 350 Credit to: Principle of Textile Testing by J.E.
