High-strength thread is essentially a kind of sewing thread. This thread has good tensile force, high speed and high temperature resistance, and the thread itself is glossy as a heavy duty sewing thread. Some shoe industry, bag industry and sofa industry like to use this thread. In fact, the industry recognized high strength thread or the most suitable for leather sewing thread.
High strength line is also used to suture all kinds of clothing materials at ordinary times, is a practical and decorative two kinds of line. Therefore, the quality of the high-strength thread, which plays an important role in stitching, will not only affect the sewing effect of the thread, the production cost, but also the appearance of the stitched product. Therefore, professionals will be high strength filament thread temperature resistance, strength degree, twist, suture type and so on as a few points, convenient factory enterprises to develop relevant standards.
Several classifications of high-strength lines:
Cotton high strength sewing thread -- cotton fiber as raw material after rinsing, sizing, waxing and other links to make sewing thread, inside can also be subdivided, this thread has high strength, good heat resistance, suitable for sewing technology and durable pressing technology, the disadvantage is that elasticity and wear resistance is not good.
Silk LINE -- -- MADE LONG SILK LINE WITH NATURAL SILK OR SILK SILK LINE, BURNISH IS BEAUTIFUL, WEAR RESISTANCE OF STRENGTH, ELASTICITY IS BETTER THAN COTTON LINE, USE AT SEWING HIGH-GRADE CLOTHING COMMONLY
Polyester high-strength thread -- made of polyester filament or staple fiber, strength, wear resistance and elasticity are good, shrinkage rate is low, but the disadvantage is high speed and easy to melt, the production will be easy to plug the needle eye, mainly used for jeans, sports clothing, it should be noted that it is currently the most popular type of high-strength thread.
Polyamide fiber high-strength line --, made of nylon multifilament, there are also several small classification, the most commonly used is long silk, has a large extent, the characteristics of good elasticity, it is mainly used for chemical fiber of this kind of elastic garment sewing, but the downside is that the low stiffness, and not high temperature resistant, so make sewing speed cannot too fast, also can apply to make decals, stand side not force position.
Acrylic high strength thread -- low twist, mainly used for decorative embroidery.
Viylon high strength thread -- high strength, mainly used for sewing thick clothes, such as labor protection supplies and so on.
Polyester/COTTON HIGH-STRENGTH THREAD IS MADE OF 35% COTTON AND 65% DACRON BLENDED, WITH HIGH STRENGTH, ABRASION RESISTANCE, HEAT, SHRINKAGE AND SUPER good, ESPECIALLY suitable FOR HIGH-SPEED SEWING technology.
Cored high-STRENGTH yarn -- filament as its core, core thread determines the strength, the outer yarn determines the wear resistance and heat resistance, making high firm clothing.
