EXAMPLE III
Taking the pure cotton fabric as grey cloth, and finishing the grey cloth through different procedures to obtain a finished fabric;
it should be noted here that the pure cotton fabric is selected as the grey cloth of the shirt fabric, which is convenient for the user to clean the shirt, because the hydrophilic segment of the fluorine-containing soil release finish cooperates with the hydrophilic group of the pure cotton fabric in an aqueous solution to minimize the interfacial energy of the fabric, and thus the dirt on the pure cotton fabric can be easily separated from the fabric.
The specific process of different procedures comprises the following steps:
s1, desizing treatment: and (3) desizing the grey cloth through a desizing process to obtain the grey cloth I, wherein the desizing process comprises enzyme desizing, alkali desizing, oxidant desizing and acid desizing.
S2, high-temperature water washing: after desizing, the grey cloth I is cleaned by hot water in time to obtain a grey cloth II, impurities such as decomposition products of starch of the desized grey cloth I can be condensed on the fabric again, so that the subsequent processing process is seriously hindered, and because the conditions of the enzyme desizing process are mild, the water washing speed is 60m/min, the water temperature of the initial washing tanks is 70 ℃, the water temperature of the middle washing tanks is 90 ℃, and the water temperature of the tail washing tank is 50 ℃ to obtain a good desizing effect.
S3, mercerizing and singeing: burning fine fluff on the surface of a second cotton fabric of the second grey cloth through an annular flame jet of a singeing machine, puffing molecular bond gaps and expanding cells of the second cotton fiber of the second grey cloth through a thick alkali process of a mercerizing machine, and enabling the surface of the second cotton fabric of the second grey cloth to be smooth and round under the action of soft water injection to obtain a third grey cloth; thereby increasing the three-fiber luster of the grey cloth and improving the brightness of the cotton fabric;
s4, liquid ammonia finishing: liquid ammonia is a small-molecule, low-viscosity and high-polarity fiber swelling agent, can quickly permeate into the inner part of the rayon fiber, has uniform swelling effect, and is easy to remove. After the cotton fibers are treated by the liquid ammonia, the cross section of the cotton fibers is round, the cavity diameter is reduced, the surface is smooth, the crystalline structure is changed, the internal stress is eliminated, the tensile strength and the tearing strength are improved, and the good hand feeling can be still kept even if the cotton fibers are repeatedly washed. For yarn-dyed fabrics with higher quality requirements, soft luster, soft hand feeling, better crease resistance and higher dimensional stability can be obtained through liquid ammonia finishing, the elasticity, wear resistance, tearing strength and the like of the fabrics can be improved, and the grade of the yarn-dyed fabrics is greatly improved;
the process flow comprises cloth feeding → pre-drying → cooling → liquid ammonia treatment (padding liquid ammonia → drying) → steaming → water washing → drying → cropping.

S6, baking: preheating the dryer at the preheating temperature of 110 ℃ for 100s, and then placing the grey cloth IV on a drying rack of the dryer for baking at the baking temperature of 155 ℃ for 3 min.
And S7, preshrinking, namely preshrinking under the action of mechanical pressure through the rubber blanket to control, and preshrinking in the weft direction is realized by controlling the width of the cropping cloth.
