Later on jute, silk, linen, were used. Then cotton threads became so popular. Today is the era of synthetic threads where these threads are specially engineered to satisfy the functional requirements of the end products. Sewing threads may be defined as smooth, evenly spun, hard-twisted ply yarn, treated by the special finishing process to make it resistant to stresses in its passage through the needle eye and through material involved in seaming and stitching operation.The overall performance in terms of strength, durability and usefulness of the substrate depends on the sewing thread. Though the consumption of sewing thread is not more than 1% of the textile to be sewn, they are of considerable importance.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/53/361/737/1533617376_b.jpg", "price_data" : { "retail_price" : "50.00", "online_price" : "50.00", "our_price" : "50.00", "club_price" : "50.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
