Description
Technical Field
A denim sizing process belongs to the technical field of grey cloth finishing.
Background
As the consumption style of the products in the current jean market is changed, the varieties of pure cotton are gradually reduced, and the varieties of elastic fabrics are gradually increased. The traditional finishing equipment can not meet the finishing requirement of the jean fabric, and when the finishing elastic cloth variety is produced, the conventional process is adopted: rinsing, weft straightening, drying, preshrinking, blanket drying and cropping. The weft shrinkage index is unstable, namely the width is unstable, and the elastic recovery of the elastic cloth is unstable, so that the elastic cloth is not easy to master and lose elasticity, and the weft is larger and reaches more than 2%.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art, and provides a denim setting process with stable fabric width and good elasticity.
The technical scheme adopted by the invention for solving the technical problems is as follows: the denim setting process is characterized by comprising the following steps: finishing the denim twice;
the first-pass finishing process comprises the following steps: singeing gray fabric, passing through a water tank and a padder, drawing, drying, shaping a blanket, and pre-shrinking and cropping;
the second finishing process comprises the following steps: singeing gray fabric, passing through a water tank and a padder, skewing, drying, preshrinking a rubber blanket, shaping the blanket, and preshrinking and cropping;
wherein, in the blanket shaping process in the first finishing, the steam pressure of a large drying cylinder is 3.8Kg to 4.2Kg, the steam pressure of a small drying cylinder is 3.8Kg to 4.2Kg, and the temperature is controlled to be 111 ℃ to 116 ℃;
in the blanket shaping process in the second finishing, the steam pressure of a large drying cylinder is 3.8-4.2 Kg, the steam pressure of a small drying cylinder is 3.8-4.2 Kg, and the temperature is controlled to be 101-105 ℃.
The invention adopts the blanket shaping process to solve the problem, and all indexes are improved to reach the standard. The process of the invention does not need a grey cloth sizing procedure, the production efficiency is obviously improved, the first finishing does not use a glue-opening blanket drying cylinder, the purpose of saving steam is achieved, and multiple purposes are achieved. In the shaping process, the jean is only finished by the blanket during the first production finishing; the temperature of the blanket is accurately controlled during production and finishing. The blanket is in direct contact with the jean fabric, heat energy of the blanket is conducted to the fabric, the jean fabric is kept at a certain temperature, and the jean fabric is dried, so that the purpose of primarily shaping the elastic jean fabric is achieved. Therefore, the ironing and shaping effects on the cloth can be achieved, and the width of the plant is stabilized; but also can reduce the direct contact between the surface of the high-temperature drying cylinder and the denim, which causes the elasticity of spandex elastic yarns in the elastic denim to be damaged and lose elasticity, and keep good elasticity.
The device used in the blanket shaping procedure in the first finishing and the second finishing comprises a large drying cylinder, a small drying cylinder and a blanket temperature controller, wherein blankets are arranged on the large drying cylinder and the small drying cylinder, and running jeans are arranged between the large drying cylinder and the blankets; the running jean is arranged outside the blanket of the small drying cylinder. The big drying cylinder is directly contacted with the jean fabric, and the front side and the back side of the jean fabric are wrapped by the woolen blanket, so that the function of ironing the fabric by the woolen blanket is achieved. Avoid the woollen blanket temperature transmission slow, the stoving ironing effect is not good. The small blanket drying cylinder is only contacted with the blanket, and dries the surface of the blanket contacted with the jean fabric, thereby playing the role of drying the blanket. The situation that the surface of the blanket is high in humidity and cannot be dried is avoided. The blanket temperature control system accurately controls the surface temperature of the blanket and the surface temperature of the blanket drying cylinder. The blanket setting effect is accurately controlled, and the problem that the blanket setting effect is unstable due to the fact that the temperature of the blanket is suddenly high and suddenly low is solved.
In the first finishing step, the steam pressure of the large drying cylinder is 3.9-4.0 Kg, the steam pressure of the small drying cylinder is 3.9-4.1 Kg, and the temperature is controlled to be 113-114 ℃. The fabric ironing and shaping device can better iron and shape the fabric and stabilize the width of the fabric.
In the blanket shaping process in the second finishing, the steam pressure of a large drying cylinder is 3.9-4.1 Kg, the steam pressure of a small drying cylinder is 3.9-4.0 Kg, and the temperature is controlled to be 102-103 ℃. The direct contact between the surface of the high-temperature drying cylinder and the denim can be better reduced, and the elasticity of the spandex stretch yarn is ensured.
And the water tank and padder procedures in the first finishing and the second finishing are two sets of water tanks and padders. Two sets of water tanks and padders are continuously used, so that the blanket shaping device is not more suitable for the subsequent blanket shaping process, and the elasticity of the product is better.
The speed ratio of a pre-shrinking machine used in the pre-shrinking process of the rubber blanket is 1.05-1.08. The preferred speed ratio stabilizes the fabric width under more suitable stretching.
The water content of the jean cloth after being dried in the first finishing, the inclined drawing and drying processes is 5% -9%.
The water content of the jean cloth after drying in the drawing, inclining and drying processes of the second finishing is 4% -6%.
The preferable moisture content after drying can keep proper cloth heat conductivity in the preferable blanket shaping process, so that the width of the fabric is more stable, and the elasticity is better.
Compared with the prior art, the invention has the beneficial effects that: the invention adopts the blanket shaping process to solve the problem, and all indexes are improved to reach the standard. The process of the invention does not need a grey cloth sizing procedure, the production efficiency is obviously improved, the first finishing does not use a glue-opening blanket drying cylinder, the purpose of saving steam is achieved, and multiple purposes are achieved. In the shaping process, the jean is only finished by the blanket during the first production finishing; the temperature of the blanket is accurately controlled during production and finishing. The blanket is in direct contact with the jean fabric, heat energy of the blanket is conducted to the fabric, the jean fabric is kept at a certain temperature, and the jean fabric is dried, so that the purpose of primarily shaping the elastic jean fabric is achieved. Therefore, the fabric ironing and shaping function can be realized, and the width of the fabric is stabilized; but also can reduce the direct contact between the surface of the high-temperature drying cylinder and the denim, which causes the elasticity of spandex elastic yarns in the elastic denim to be damaged and lose elasticity, and keep good elasticity.
