Sewing machine on their perspective of the development are mostly concentrated in the application of electro-hydraulic integration of the gas, no oil or micro-oil lubrication system used, the application of direct-drive motor, multi-program control computer applications, modeling of chemical design of individual applications etc., which are pushing the development of the sewing machine to new heights. China’s sewing machine manufacturers, has launched a number of automatic bag opening machine, oil-free holzmann direct-drive sewing machines, sewing machine needle angle compound feed, single needle lateral sewing machine, electric high-speed bar tacking machine, small square head series stretch sewing machine, etc., Mulberry Alexa Bag Designer , to achieve a new leap forward sewing. Sewing machine is sewing clothes indispensable tool, different have different fabric sewing performance of fabrics holzmann and sewing machine sewing in addition to its institutions, holzmann but also with performance fabrics, sewing thread, sewing machine needles and sewing process parameters (eg pressure foot pressure, thread tension, stitch density, Mulberry Congo Briefcase , feed dog height, etc.). holzmann Such as sewing needles holzmann is one of the major pieces holzmann into the sewing machine. Needle tip shape, the needle bar shape and surface treatment of the joint appearance with absolute influence. As the process holzmann of sewing machine needle and fabric in direct contact, if the needle is incorrectly using the following problems: jumper, break, seam wrinkling, Embroidery, needle thick, high-speed needle body heat caused by friction, resulting in fused sutures and yarn and so on. Comprehensive understanding of the sewing machine needle shape, size, texture, hardness, flexibility and use for different clothing styles, different fabrics and different parts of a scientific and rational choice of sewing machine needle is very important.
Under normal circumstances, sewing thin, crisp, dense material should be used in small joints (fine) needle, and sewing thick, soft, sparse selection of sewing materials are advised to large (coarse) pin . Sewing thin material with a needle, due to the friction holzmann material sewing machine needle with a larger rise sewing machine needle needle feed will be randomly increased in pressure within the bad foot, delaying the formation of a loop of wire, causing the needle holzmann jump; sewing thick when the selected material, such as needle, the needle will cause bending or breakage of clothing styles, different fabrics and different parts of a scientific and rational choice of sewing machine needle is very important.
Currently, high-speed sewing machine sewing processing speed of up to 5000 rev / min, the needle penetrates the fabric holzmann at speeds up to 4 m / s, Mulberry Handbags , any such high-speed sewing process, the needle and Section sewing machine will lead to intense friction needle temperature is too high, severe fiber fabric will result in the formation of Rongdong or synthetic suture fusion, pinhole over the line resistance increases, so that deterioration of surface conditions caused holzmann by line into a loop or jump off the needle line of clothing holzmann styles, different fabrics and different parts of a scientific and rational choice of sewing machine needle is very important.
during high-speed sewing needle through the fabric may be cut off at any time the yarn fabric fabric caused by mechanical damage, can cause serious mechanical damage to the fabric and seam strength decreases, affecting the appearance and durability of clothing of, in general, the fabric density, compact structure and to strengthen the fabric holzmann twist in the fabric in the sewing holzmann machine damage is quite conspicuous, and short fiber yarn fabric sewing damage is relatively minor.
In recent years, in order to adapt to the diversity of performance apparel fabrics, especially holzmann the Such as Japan’s In order to solve the problem of thermal damage the needle, the use of needles direct hair, changing the shape and the needle tip rod production flow line groove method, and the development holzmann of a hollow needle through the hole of the air cooling device; the surface of the needle for special treatment, even if melting does not adhere to the needle. holzmann 150 years of experience with the Groz-Beckert holzmann needle launched the company in addition to chrome-plated needle, but also introduced nitrogen titanium alloy and nickel alloy Teflon needle, in order to meet the diverse fabric.
intelligent sewing sewing machine’s development is now at home and abroad are in focus, to be sewn of integrated system development environment. Sewability integrated environmental system cons
