1 Pre-shrink
Pre-shrinking is a process that uses physical methods to reduce the shrinkage of the fabric after soaking in water to reduce the shrinkage rate. Mechanical preshrinking is the process of spraying steam or spraying to wet the fabric, and then applying warp mechanical squeezing to increase the buckling wave height, and then dry it loosely.
2 Stenter
Tentering is a process that uses the plasticity of cellulose, silk, wool and other fibers under humid conditions to gradually widen the width of the fabric to a specified size and dry it to stabilize the shape of the fabric.
3 Sizing
Sizing refers to the finishing process in which the fabric is dipped in the slurry and dried to obtain a thick and stiff effect.
4 Heat setting
Heat setting is a process that makes the morphology of thermoplastic fibers and blended or interwoven fabrics relatively stable. It is mainly used for the processing of synthetic fibers such as nylon or polyester that are easy to shrink and deform after being heated and their blends. It can improve dimensional stability and feel more stiff.
5 Whitening
Whitening is the process of increasing the whiteness of textiles by using the principle of light complementary colors, also known as whitening. There are two kinds of whitening methods: blue and fluorescent whitening.
6 Calendering, electro-optic and embossing
Calendering is the process of making use of the plasticity of the fiber under humid and hot conditions to flatten the surface of the fabric or roll out parallel fine twills to enhance the luster of the fabric. Flat calendering consists of hard rolls and soft rolls. After the fabric is rolled, the yarn is flattened, the surface is smooth, the gloss is enhanced, and the hand feels stiff. Soft calendering consists of two soft rolls forming a soft nip point. After the fabric is rolled, the yarn is slightly flat, with a soft luster and soft hand. Electro-optical is the use of electrically heated rollers to calender the fabric. Embossing is composed of steel rolls with positive patterns and soft rolls forming nip points. Under hot rolling conditions, the fabric can obtain shiny patterns.
7 Sanding, sanding
The process of using a sanding roller (or belt) to grind a layer of short and dense fluff on the surface of the fabric is called sanding, also known as sanding. The sanding finishing can make the warp and weft yarns produce fluff at the same time, and the fluff is short and dense.
8 Fluffing
Fuzzing is the process of picking up the fibers on the surface of the fabric with dense needles or thorns to form a layer of fluff. It is also called brushing finishing. Fuzzing is mainly used for woolen fabrics, acrylic fabrics and cotton fabrics. The fluff layer can improve the warmth of the fabric, improve the appearance and make the hand feel soft.
9 Shearing
Shearing is the process of using a shearing machine to cut off unwanted hair on the surface of the fabric. Its purpose is to make the fabric weave clear and the surface smooth, or to make the pile or pile surface of the raised and raised fabric neat.
10 Soft
There are two methods of soft finishing, mechanical finishing and chemical finishing. Mechanical soft finishing is achieved by rubbing and bending the fabric many times, and the softening effect after finishing is not ideal. Chemical softening is to apply a softener on the fabric to reduce the coefficient of friction between the fiber and yarn, so as to obtain a soft, smooth hand feeling, and the finishing effect is significant.
