Steps Of Clothing Packaging Warehousing

Packaging and warehousing

The inner packing refers to one or more garments into a plastic bag. The number and size of the clothes should be identical with those marked on the plastic bags. The packing requirements are smooth and beautiful.

Some special styles of clothing should be specially handled when packaging. For example, wrinkle like clothing should be wrapped in a wrapper to maintain its styling.

The outer packing is usually packed in cartons, size and color matching according to customer requirements or process instructions.

Generally, there are four types of packaging: mixed color mixed code, single color single code, single color mixed code and mixed color only code.

When packing, attention should be paid to the complete number and accurate collocation of colors and sizes.

The outer box is marked with the box mark, indicating the contents of the customer, the port of shipment, the box number, the quantity, the place of origin, etc., and the contents are in conformity with the actual goods.

Knitted garments are mostly made of cotton and synthetic cotton yarn. They are characterized by softness, elasticity, breathability, sweat absorption and comfortable clothing, such as sportswear and underwear.

Knitted apparel, as a common garment, has its own characteristics as well as woven fabrics.

Process flow: spinning, weaving, cloth inspection, cutting, sewing, heating and testing.

(1) spinning

The purpose of spinning is to make the cotton yarn into a certain structure and specification of the roll, suitable for knitting production.

In the spinning process, we should eliminate some defects on the yarn, and at the same time make the yarn have a uniform tension, and make necessary auxiliary treatment, such as waxing and oiling, to improve the knitting performance, improve the production efficiency and improve the quality of the yarn.

(two) knitting: the process of weaving yarn into threads by weaving the yarn into string.

This is the fundamental difference between knitted garments and woven garments.

Knitting methods can be divided into two categories: weft knitting and warp knitting. Most of the knitted fabrics are weft knitted fabrics.

Weft knitting is to weft one or more yarns from the weft to the needle of the knitting machine, so that the yarns are bent in sequence and formed into weft knitted fabrics.

The machine used to weave this kind of knitted fabric is called weft knitting machine.

Weft knitting has great adaptability to yarn types and linear density, and the knitted fabrics produced are also very extensive.

Weft knitted fabrics are of wide variety. They can be woven into various kinds of fabric for internal and external use, and can also be woven into one-piece forming and partial forming products. At the same time, weft knitting process and machine structure are relatively simple, easy to operate, and the production efficiency of machines is relatively high. Therefore weft knitting has a large proportion in the knitting industry.

There are many types of weft knitting machines, which are generally distinguished by the number of needle beds, the form of needle beds and the types of needles.

Warp knitting is made up of a group or a group of parallel yarns arranged on the knitting needle and woven along the longitudinal direction.

The machine used to knit this kind of knitted fabric is called warp knitting machine.

The warp knitted fabric has better dispersion and extensibility than weft knitted fabric. Its structure and shape are of better stability. Its use is wider. Besides producing fabric for clothing, it can also produce mosquito nets, curtains, lace decorative fabrics, medical fabrics, etc. warp knitting machines can also be distinguished by needle beds and needle needles.

(three) cloth inspection

Since the quality of grey cloth is directly related to the quality and output of the finished products, it is necessary to check the number, size, density, batch number and line density of the fabric according to the requirements of the cloth batching list before cutting. When inspecting the cloth, the gray cloth should be checked one by one according to the standard, and the marking and quality records of all kinds of defects that affect the quality of the finished products, such as coloured flowers, needle holes, holes and oil stains, must be made.

(four) tailoring

The main technological process of knitted garment cutting is: cutting material, borrowing defects, drawing, cutting and binding.

Borrowing defects is an important part of improving product quality and saving materials. It is possible to borrow defects on gray fabric as far as possible during the process of cutting materials.

Knitted fabrics are cut according to meridian mesh accessories. Generally, tailoring is used for trimming. There are commonly used flat sleeves, mutual sleeves, inserts, splicing sleeves, and split sleeves.

Knitted fabrics should be noted in the following aspects:

(1) do not use folding marks and printed edges to use the obvious parts of clothing.

(2) do not use taper hole marks in the tailoring so as not to affect the appearance of the garment.

(five) sewing

The existing sewing technology and equipment in China's knitting industry are mainly sewing machines with medium and high speed sewing machines (commonly known as "flat cars"), middle and high speed sewing machines (commonly known as "Ke Ke cars"), and sewing machines.

Since knitted fabric is made up of coil sleeves, the edges of the cutting edges are easy to take off. Therefore, we should first sew the edges of the clothing pieces (commonly known as "edge") and then sew them with sewing machines.

Sewing machine and sewing machine are the main types of sewing knitted fashion.

In the sewing process, we should generally pay attention to the following key points.

1. the stitch of stitch knitted fabric should be satisfied because of the longitudinal and lateral extensibility of the knitted fabric and the easily broken edge coil.

(1) stitches should have tensile properties and strength compatible with knitted fabrics.

(2) stitches should be able to prevent the fabric from being broken.

(3) properly control the density of seam.

For example, the stitching density of thick fabric sewing machine is controlled at 9~10 pin / 2cm, the stitching density of sewing machine is 6~7 needle / 2cm, the stitching density of thin fabric is 10~11 pin / 2cm, and the stitching density of sewing machine is 7~8 pins / 2cm.

2. stitches

The pure cotton knitted fabric is made of pure cotton and polyester / cotton blended yarn with 9.8tex * 4 or 7.4tex * 3. The chemical fiber knitted fabric adopts 7.8tex * 2 elastic nylon yarn and 5tex * 6 nylon line.

The following quality requirements must be met:

(1) combed cotton yarn should be used for sewing pure cotton thread (suture). It has high strength and evenness.

(2) the suture should have some elasticity to prevent breakage during the sewing process.

(3) suture must be soft.

(4) the suture must be smooth and smooth, so as to reduce the obstruction or friction of the suture line slot and pinhole, and avoid defects such as broken line and uneven stitch tension.

3. stitches

Sewing needles are also called sewing needles and machine needles.

In order to achieve the ideal fit of stitches, stitches and stitches, the appropriate stitches must be selected.

(six) ironing

The knitted garments are made smooth through appearance and size.

When the iron is pressed, the lining plate is inserted into the garment to make the product maintain a certain shape and size. The size of the lining board is slightly larger than that required by the garment, so as to prevent the size of the liner from being too small after retraction.

The temperature of the ironing is generally controlled between 180 and 200 degrees.

(seven) finished product inspection

The finished product inspection is a comprehensive inspection before the product is released, including the two major items, the appearance quality and the internal quality. The content of the appearance inspection includes size tolerance, appearance defect and seam fastness.

The internal testing items include fabric unit area weight, color fastness, shrinkage rate and so on.
