Since the beginning of the new century, the use of industrial sewing/sealing thread has become increasingly widespread in various industries. The selection of raw materials is now mostly changed to 29.5 tex large chemical fiber, with 20 polyester fibers as the main raw material. Since our company entered the wire manufacturing industry in 1995, the selection of raw materials has also undergone a series of reforms, research, and innovation efforts. The early types of raw materials include cotton, vinylon, polypropylene, and polyester. Cotton fibers have good heat and corrosion resistance, but due to their low strength, high production costs, and water resistance, they were phased out in the late 1980s. Polypropylene fibers have low costs but poor heat resistance, After testing, it softens when it reaches 145 ℃ and is extremely resistant to aging, acid, or alkali. Therefore, it is not suitable for industrial sewing and packaging lines. Vinylon and polyester raw materials are both acid, alkali, mold, and moth resistant. Since the beginning of the new century, the use of industrial sewing and packaging lines has become increasingly widespread in various industries. The selection of raw materials is now mostly changed to 29.5 tex large chemical fibers, with 20 counts of polyester raw materials being the main material. Since our company entered the wire manufacturing industry in 1995, the selection of raw materials has also undergone a series of reforms, research, and innovation efforts. The early types of raw materials include cotton, vinylon, polypropylene, and polyester.

Therefore, it is not suitable for industrial sewing and sealing lines. Vinylon and polyester raw materials have the characteristics of acid, alkali, mold, and water resistance, and are also high-temperature resistant. The softening temperature of vinylon is 220 ℃, and that of polyester is 204 ℃. However, compared to the two, the shortage of vinylon raw materials is due to the fact that the price of vinylon raw materials is one-third higher than that of polyester raw materials, The main difference is that in terms of strength/aging resistance and smoothness, polyvinyl alcohol is not as good as polyester. Therefore, Shuangli brand polyester tower thread is a cost-effective and ideal high-quality sewing and packaging thread.

Industrial sewing and sealing threads account for a relatively small proportion of various materials used in packaging, and people tend to overlook their unique role. In the market, various brands and unbranded industrial sewing and sealing threads have different usage effects due to the different materials used. Moreover, a large number of "three no" products (without trademarks, manufacturers, or quality indicators) have low quality, which brings many difficulties to sewing machines and sealing machines during the sewing process, Due to frequent thread breaks and skipped stitches, the production line has been forced to reduce production, causing damage to packaging materials, affecting human, financial, and material resources. Some have also wronged the quality of sewing and packaging machines, bringing unpredictable hidden dangers to the products of manufacturers.

[Selection Method for Shuangli Brand Industrial Sewing and Sealing Thread]

Shuangli brand industrial sewing and sealing lines are suitable for packaging and sewing in industries such as chemical, fertilizer, feed, cement, salt fields, woven bags, ports and docks, fishing companies, and shoemaking. The products are soft and smooth, with bright colors, uniform thickness and no knots, high strength, and have characteristics such as acid, alkali, wear, mold, and non-toxic. Customers must recognize Shuangli"s high standards before purchasing and be cautious of counterfeiting.

Shuangli brand industrial sewing and wrapping thread, sealing thread, and twisting equipment are advanced and the process is reasonable. They are produced according to national standards, and the execution standard is GB/T6836-2007. When selecting, the main focus should be on observing that the suture should be continuous, consistent, and tight, with a pure white appearance and uniform thickness. There should be no stuttering or tangles, and there should be a certain degree of willfulness. The twist should be even, and there should be no significant twisting force. The test method is to cut one meter of suture and grasp both ends to form a large circle. At this time, the twisted twisted circle should not exceed 5.

How to Calculate the Meters per kilogram of Shuangli Brand Industrial Sewing and Sealing Thread Series Products

In our daily sales activities, whether it is a customer or our sales team, as long as we make a phone call, we will immediately report the required specifications, thickness, and thickness of polyester packaging wire. Enterprises are carefully calculating and reducing costs, because the finer the wire, the longer the number of meters, and some small packaging bags only need thinner lines, which can save costs.

1. Our sewing thread currently uses 29.5tex ×  20 yarns, that is, one strand with a length of 1000 meters weighs 29.5 grams.

2. Blending shrinkage: (1) The full name of the yarn is 29.5tex 20 count polyester yarn; (2) The merging and shrinking ratio (2 shares 1.02... 3 shares 1.03... 4 shares 1.04... 5 shares 1.05... 6 shares 1.06... 7 shares 1.07... 8 shares 1.08... 9 shares 1.09... 10 shares 1.1... 11 shares 1.11... 15 shares 1.15) is used to smoothly calculate and calculate the length of various shares per kg:

one × 2 (2 strands) passing through the parallel line, with a weight of (1) per 1000 meters × 2) × 29.5 g × If the shrinkage of 1.02 is equal to 60.18 grams, then 1 kilogram 11 × 2 (2 strands) passing through the parallel line, with a weight of (1) per 1000 meters × 2) × 29.5 g × If the shrinkage of 1.02 is equal to 60.18 grams, then 1 kilogram 1 × Length of 2: 1000 grams ÷ 60.18 × 1000 is approximately 16600 meters. And so on:

one ×  3 (3 strands): 1 kg length 1000 grams ÷<1 × three × twenty-nine point five × 1.03> × 1000 is approximately 10800 meters

one ×  4 (4 strands): 1 kg length 1000 grams ÷<1 × four × twenty-nine point five × 1.04> × 1000 is approximately 8100 meters

one ×  5 (5 strands): 1 kg length 1000 grams ÷<1 × five × twenty-nine point five × 1.05> × 1000 is approximately 6450 meters

one ×  6 (6 strands): 1 kg length 1000 grams ÷<1 × six × twenty-nine point five × 1.06> × 1000 is approximately equivalent to 5400 meters

two ×  3 (6 shares): Same as above, approximately equal to 5400 meters

three ×  3 (9 strands): 1 kg length 1000 grams ÷<1 × nine × twenty-nine point five × 1.09> × 1000 is approximately 3400 meters

Our sales need to consider our customers and provide our product data in order for them to understand! The characteristic of being afraid of water and resistant to high temperatures, with a softening temperature of 220 ℃ for vinylon and 204 ℃ for polyester. However, compared to the two, there is a shortage of vinylon raw materials, as the price of vinylon raw materials is one-third higher than that of polyester raw materials. The main reason is that in terms of strength/aging resistance and smoothness, vinylon is not as good as polyester. Therefore, Shuangli brand polyester tower thread is a cost-effective and ideal high-quality sewing and packaging thread.
