Understanding And Application Of Sewing Thread For Garment Accessories

< p > < strong > First: the classification and characteristics of sewing thread < /strong > < /p >.

< p > > a href= "//www.sjfzxm.com/" > sewing thread > /a > the most commonly used classification method is raw material classification, including three categories: natural fiber sewing thread, synthetic fiber sewing thread and mixed sewing thread.

< /p >

< p > < strong > 1. Natural fiber sewing thread < /strong > /p >

< p > A. cotton sewing thread: sewing thread made of cotton fiber as raw material by refining, bleaching, sizing and waxing.

High strength, good heat resistance, suitable for high-speed sewing and durable press. The disadvantage is that elasticity and wear resistance are poor.

It can also be divided into no light (or soft line), silk light and wax light.

Cotton sewing thread is mainly used for sewing cotton fabrics, leather and high temperature ironing clothes.

< /p >

< p > B. silk thread: long silk or silk thread made of natural silk has excellent luster, and its strength, elasticity and wear resistance are better than cotton thread. It is suitable for sewing various kinds of silk garments, high-grade woolen garments, fur and leather garments.

Silk embroidery threads commonly used in ancient China Embroidered exquisite decorative embroidery.

< /p >

< p > < strong > synthetic fiber sewing thread < /strong > /p >

< p > A. < a href= "//www.sjfzxm.com/" > polyester sewing thread < /a >: is the main sewing thread at present, made of polyester filament or staple fiber as raw material.

It is characterized by high strength, good elasticity, wear resistance, low shrinkage and good chemical stability. It is mainly used for sewing jeans, sportswear, leather products, wool and military uniform.

It should be noted that the melting point of polyester suture is low, it is easy to melt at high speed sewing, blocking the needle eye, causing the suture to break, so it is not suitable for clothing with too high speed stitching.

< /p >

< p > B. < a href= "//www.sjfzxm.com/" > nylon sewing thread < /a > nylon sewing thread is made of pure nylon multifilament, which is divided into three kinds: long silk thread, short fiber dimension line and elastic deformation line. At present, the main varieties are nylon long silk thread.

It has the advantages of high elongation and [MSOffice3], good elasticity, and its breaking length is three times higher than that of the same specification cotton. Therefore, it is suitable for sewing chemical fiber, woolen cloth, leather and elastic clothing.

The greater advantage of nylon sewing thread lies in the development of pparent sewing thread. As the line is pparent and chromaticity, it reduces and solves the difficulties in sewing wiring, and has broad prospects for development. However, limited to the present market, the rigidity of the pparent wire is too large and the intensity is too low. The stitch is easily floated on the surface of the fabric, and it is not resistant to high temperature, and the sewing speed can not be too high. It is mainly used for sewing applique and stacking edges, but not for sewing.

< /p >

< p > C. vinylon sewing thread: made of vinylon fiber, its strength is high and its stitches are stable. It is mainly used for sewing thick canvas, furniture cloth, labor protection articles, etc.

< /p >

< p > D. acrylic sewing thread: made of acrylic fiber, mainly used for decorative and embroidery threads, with low twist and bright coloring.

< /p >

< p > < strong > mixed sewing thread < /strong > /p >

< p > A. polyester / cotton sewing thread: 65% polyester and 35% cotton blended.

It has the advantages of both polyester and cotton, which can not only guarantee the strength, wear resistance and shrinkage rate, but also overcome the defects of polyester and heat resistance, and adapt to high-speed sewing.

It is suitable for all kinds of garments including cotton, polyester / cotton and so on.

< /p >

< p > B. core sewing thread: sewing thread made of filament yarn and wrapped with natural fibers.

The strength depends on the core line, and the wear resistance and heat resistance depend on the outer yarn.

Therefore, the core sewing thread is suitable for high speed sewing and high strength clothing.

In addition, sewing thread can also be divided into coil, line, bobbin, thread ball and so on according to the form of packing. It can be divided into sewing thread, embroidery line and industrial line.

< p > >: < strong > the quality and application of sewing thread < /strong > < /p >

< p > the comprehensive index of sewing thread < a href= "//www.sjfzxm.com/" > mass < /a > is stitching property.

Stitching means that sewing threads can stitch and form good stitches under specified conditions and maintain certain mechanical properties on line traces.

The advantages and disadvantages of stitching will directly affect garment production efficiency, sewing quality and wearability.

According to the national standard, the grade of sewing thread is divided into grade one, grade two and other grade.

In order to make sewing thread have the best stitching in garment processing, the sewing effect is satisfactory. It is very important to select and apply sewing thread correctly.

The correct application of sewing thread should follow the following principles: < /p >

< p > 1 is compatible with fabric characteristics: sewing thread and fabric materials are the same or similar, so as to ensure their shrinkage, heat resistance, wear resistance, durability and so on.

< /p >

< p > 2 is consistent with clothing: for special purpose garments, sewing threads with special functions should be considered, such as elastic clothing, elastic sewing thread, and fire-fighting clothing with heat resistant, flame retardant and waterproof treatment thread.

< /p >

< p > coordinate with stitch form: the stitches of different parts of garments are different. Sewing threads should also be changed accordingly. For example, the lines or deformation lines need to be used to expand the stitches. Double line stitches should be chosen with extended lines. The crotch seam and shoulder suture should be fastened, while the eyeliner should be wear-resistant.

< /p >

< p > quality and price: the quality and price of sewing thread should be unified with the grade of garments. The quality of sewing is high quality and the price is high.

Generally speaking, the grade of sewing thread, the raw materials and the fineness of yarn are all marked on the label of sewing thread, which is helpful for us to choose and use sewing thread reasonably.

The sewing thread < a href= "//www.sjfzxm.com/" > sign < /a > usually includes four contents (in sequence): yarn thickness, color, raw material, processing method, can be expressed in the form of "60/2X3 white polyester line".
