Most knitted garments of cotton and chemical fiber yarn is as raw material, which is characterized by soft, flexible, breathable, absorbent, comfortable, such as sportswear and underwear. As a garment knitted garments and woven garments in addition to common areas, but also has its own characteristics.
The purpose of spinning cotton yarn is wound into the plant to make into a certain structure and specifications of the cheese rolls to fit knitting production. In the process of spinning yarn to eliminate the existence of some defects, while a certain uniform yarn tension, the yarn necessary to assist in processing, such as wax, oil on to improve the performance of knitting yarn, increase productivity and improve product quality.
(B), weaving
Weaving the yarn through the loom to make the organization into line with each other string sets the volume to become the fabric of the process. This is the knitwear and woven apparel fundamental difference.
Weaving methods can be divided into two major categories of warp and weft, as a knitted fabric with clothes mostly weft fabric. Is one or several weft yarn from the weft knitting machine work feeding needle, so that the yarn in order to bend into a circle, and the string to be set to form weft knitted fabric. Used to weave this machine called the weft knitted fabric knitting machine. Type of weft yarn processing and linear density greater adaptability, the production of knitted fabric is also very wide range of varieties. Wide variety of weft knitted, woven into a variety of organizations both within the coat with fabric, can be woven into a single piece of molding and forming part of the product, while the process and machine weft structure is relatively simple, easy to operate, the machine production more efficient, therefore, weft knitting industry in a larger proportion. Many types of weft knitting machine, usually the number of the needle bed, needle and needle bed forms and categories to distinguish. Warp by a group or several groups of parallel yarns were arranged on the needle, while along the vertical weave. For weaving machines such as knitted warp knitting machine. General decoherence by knitted and weft knitted fabric than a small extension, the stability of its structure and shape better, its use is also wider, in addition to produce clothing with fabric, but also production of mosquito nets, curtains, lace decorative fabrics, medical fabrics, etc., can also warp knitting machine with needle bed knitting needles needle to make that distinction.
(C), inspecting
As the fabric quality is directly related to the quality and quantity of the finished product, so the cut before cutting cloth must be based on a single ingredient, check the piece number, size, density, lot number, the line density is in line with the requirements of the test cloth fabric when the standard tested one by one, affecting the quality of the finished product all kinds of defects, such as flower color, missing pin, holes, oil, etc. to be well marked and quality records.
(D), cut
Knitwear cutting the main process: breaking through the material defect → → → cut → draw like banding.
By the defect is to improve product quality, saving an important part of material, cutting the fabric on the process as much as possible to cut consumption by the defect site or suture.
Knitted mesh fabric according to the materials by cutting, cutting sets of cutting methods commonly used, commonly used level sets, each set, inlay, mosaic sets, sewing sets, etc. profile.
Knitted fabrics in the cut should note the following: 1, do not have fold marks and printed at the edge of the obvious use in the clothing area. 2, cone cut, do not use tags, so as not to affect the appearance of clothing.
(E), sewing
China's knitting industry is available in the sewing process and equipment, high-speed sewing machine (commonly known as "flat car"), the speed bag sewing machine (commonly known as "copy g car"), stretch sewing and other models of sewing machines .
As the knitted fabric is formed by the coil sets of strings, cut the edge of the garment after prone to decoherence, it should first edge of the garment bag seam (commonly known as "copy-side") and then use the sewing machine and other sewing process. Sewing machine and sewing machine is sewing knitting fashion pack the main models. In the sewing process in general should pay attention to grasp the following points.
1 stitch knit fabric because the fabric has a vertical and horizontal extension (ie, flexible) edge of the coil characteristics and shortcomings of decoherence and easy, so stitch sewing knitting fashion should be met:
(1), the stitch should be compatible with the knitted fabric and tensile strength. (2), stitch the fabric should be able to prevent the coil decoherence. (3), proper control of stitch density. Such as the thick fabric sewing machine stitch density control in 9 to 10 pin / 2cm, overlock stitch density of 6 to 7 pin / 2cm, thin fabric of the sewing machine stitch density control in 10 to 11-pin / 2cm, overlock stitch density of 7 to 8 pin / 2cm.
2, generally cotton knitted fabric with stitching 9.8tex × 4 or 7.4tex × 3 line of cotton and polyester blend, synthetic knit fabric with 7.8tex × 2 stretch nylon silk and nylon line 5tex × 6 . Sutures to achieve the following quality requirements:
(1), sewing machine with a cotton line (stitches) should be combed line, it has high strength and uniformity. (2), suture should have some flexibility, to prevent the sewing process will not bend or squeeze because the line break occurs the phenomenon. (3), the suture must have flexibility. (4), the suture must evenness smooth groove and pinhole to reduce suture line is blocked or friction, to avoid disconnection and uneven stitch tension and other defects.
3. Needle sewing machine needle, also known as needle, needle. In order to achieve the needle and suture material, suture with the ideal, we must choose the right needle.
(F), ironing
Knitted garments by ironing to look smooth, quasi-foot size. Ironing clothes when the inner sleeve into the liner in the product to maintain a certain shape and size, liner size slightly larger than those required clothing to prevent retraction after the size is too small. Ironing temperature is controlled at between 180 ℃ ~ 200 ℃ is more secure, easy to hot yellow, coking.
(G), product testing
Finished product testing is a comprehensive factory inspection, including the quality and appearance of the two major projects within the quality, appearance, content inspection and dimensional tolerances, appearance defects, stitch fastness and so on. Projects within the test weight per unit area of fabric, color fastness, shrinkage and so on.
