Finishing definition
A combination of physical, chemical, or physical and chemical methods to improve the appearance and intrinsic quality of apparel fabrics, improve performance and other application properties, or impart a special function to the fabric.
Fabric
Finishing purpose
1. Stabilize fabric size and shape
Stretching - the use of cellulose, silk, wool and other fibers in a certain degree of plasticity under wet conditions, the fabric width is gradually widened to the specified size and drying and stable finishing process, also known as the fixed width.
Heat setting - refers to the processing technology in which the fiber fabric is heat treated under a certain tension to make its size and shape stable.
2, improve the appearance of apparel fabrics
Singeing: The fluff on the surface of cotton and its blended textiles is removed by direct flame burning to make the surface smooth and smooth, which facilitates the smooth processing of subsequent processing and guarantees product quality. The flame temperature of the singeing is usually 900 to 1000 ° C, and the surface temperature of the hot metal plate is also 800 ° C, which is higher than the decomposition temperature or ignition point of various fibers.
Calendering: Through the mechanical pressure of the calender, the effect of damp heat, by means of the plasticity of the fiber, the surface fibers are arranged in parallel to improve the smoothness of the surface, the regular reflection of light, and the purpose of improving the color of the fabric.
Rolling finishing: The embossing machine consists of a heated hard roll and a soft roll. The surface of the hard roller is engraved with a yellow pattern, and the soft roller is engraved with a negative pattern. During the finishing, by means of the plasticity of the fabric under moist heat conditions, the fabric is pressed by the yin and yang roll to produce an effect of the embossing pattern on the fabric.
Sanding: After finishing, the fabric can produce suede, which has improved hand feeling and comfortable wearing. It can be made on the brushing machine, and the fabric is repeatedly rubbed to produce suede.
3, improve the softness of the fabric feel:
Soft finishing is a process that compensates for the softness and roughness of the fabric and makes the fabric soft. Including mechanical soft finishing, chemical soft finishing and stiff finishing.
Mechanical soft finishing mainly uses mechanical methods to bend the fabric multiple times under tension to reduce the rigidity of the fabric so that it can be restored to an appropriate degree of softness.
The chemical method uses a softening agent to reduce the coefficient of friction between the fibers to obtain a softening effect.
Stiffness finishing is to make the fabric smooth, stiff, thick, full of hand, and to improve strength and wear resistance, but also to enhance the body and improve the appearance.
The stiffening finishing process is generally carried out in combination with the fixed width, and a softener is added to the slurry to improve the comprehensive hand feeling. Similarly, a simple soft finishing process is to add a stiffening agent to reinforce the body bone.
4, improve the durability of apparel fabrics
Flood control
The auxiliaries used in anti-mite finishing should be highly efficient and low-toxic, have no side effects on the human body, and do not affect all aspects of the fabric. Commonly used anti-mite finishing methods include wool chemical modification method and anti-caries agent finishing method.
(1) Wool chemical modification method: a new and stable cross-linked structure is formed by chemical modification. When the mites eat this cross-linked structure, it is difficult to digest and finally kill, thereby improving the anti-caries property.
(2) Anti-caries agent finishing method: The wool fiber is directly brought to the chemical agent which kills the aphids by tidying, and these drugs are directly immersed in the aphid skin layer or killed by the respiratory organs and digestive organs.
5, give the fabric special performance
Commonly, there are waterproof finishing, water repellent finishing, and flame retardant finishing.
Waterproof finishing is to coat the fabric so that both water and air are not permeable; water repellent finishing is to make the hydrophilicity of the surface of the fiber hydrophobic, and the fabric is both breathable and not easily wetted by water.
Flame-retardant finishing, the finished fabric has different degrees of ability to prevent flame spread, and can quickly stop burning after leaving the fire source.
There are three ways to flame retardant finishing:
(1) Exhaust combustion method: a flame retardant is bonded to a cellulose fiber or a chemical fiber by an ionic bond or a covalent bond, so that it is insoluble in the fiber to obtain a durable flame retardant effect.
(2) Raw liquid method: The flame retardant is directly added to the spinning solution.
(3) Copolymerization method: the flame retardant is added to the polymer segment to make the fabric have the fastness of washing, bleaching, perspiration and the like, and is not absorbed by the skin. The printing and dyeing factory mainly adopts the first method.
