Description

Technical Field

[0001] The invention relates to the technical field of cashmere fabrics, and in particular to a production process and production equipment of cashmere fabrics. Background Art

[0002] As people's living standards improve, the requirements for clothing fabrics are getting higher and higher, shifting from the original simple warmth retention to the pursuit of fashion, decoration, functionality and health care, further promoting the development of the fabric industry.

[0003] Cashmere fabric is a kind of cashmere-like effect, with the characteristics of soft hand feel, soft luster and good warmth retention. However, the color fastness and sunlight fastness of the fabric produced by the traditional cashmere-like fabric process are often only between 3.5 and 4 levels. This means that when the fabric needs to be used in specific occasions, its color fastness and sunlight fastness requirements are relatively low, and it is easy to fade. Summary of the invention

[0004] To this end, the present invention aims to provide a production process and production equipment for cashmere fabrics.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A production process of cashmere fabric, comprising the following steps:

[0007] Setting: The semi-finished fabric woven from yarn is set at high temperature;

[0008] Gluing: The wool surface of the semi-finished fabric is glued by a glue bonding machine;

[0009] Napping: The nap surface of the semi-finished fabric after the gluing in step 2 is napped by a napping machine;

[0010] Perm and cut: Use a high-temperature perm machine to perm the fluff pulled out in step 3 to a uniform length;

[0011] Dyeing: Dyeing is done by dyeing machine;

[0012] Setting: Setting temperature is 185-190℃;

[0013] Finished product rolling: The fabric is rolled up through a winding machine.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention adjusts the traditional processing method by first performing gluing and then performing napping and ironing and shearing, so that the fluff on the produced fabric is more abundant and diverse, and has a strong three-dimensional effect. In addition, due to the adjustment of the process, after the process sequence of first gluing and then napping, ironing and shearing, dyeing, and finally high-temperature curing at 185-190°C is determined, the color fastness of the dyed fabric can be more excellent, which can be improved from the traditional color fastness and sunlight fastness of 3.4 levels to 4 levels, and the dry temperature film of 4 levels is improved to 4.5 levels, and the product performance is more excellent.

[0016] As an improvement, before the step (5), the opened fabric is first soaked in a solution containing 1 g / L acetic acid at 55°C for 10 minutes, then rinsed with soft water to adjust the pH value to between 6 and 6.4, and then soaked in a penetrant at above 60°C for 30 minutes. This can serve as a preheating agent, resulting in a better dyeing effect.

[0017] As an improvement, in step (2), the laminating machine is used to laminarize the fleece surface of the semi-finished fabric at a speed of 35 m / min, the temperature of the hot pressing roller is 175° C.-160° C., the pressure is 5 kg, and there are two ovens, the first oven is 110° C., and the second oven is 85° C. In this way, the laminating effect is good and the fastness is high after drying in the oven.

[0018] As an improvement, the dyeing machine is an overflow dyeing machine.

[0019] As an improvement, the high temperature setting temperature in step (1) is 180°C.

[0020] The present invention also provides a production process of cashmere fabric production equipment, including a high-temperature scalding machine, which includes an outer box body, the outer box body is provided with an inlet and an outlet for fabric, and a first material guide roller group, a scalding device, a second material guide roller group, a dust cleaning device and a third material guide roller group are sequentially arranged inside the outer box body along the conveying direction of the fabric, the first material guide roller group and the second material guide roller group are horizontally arranged inside the outer box body, and can drive the fabric to be conveyed forward, the scalding device is located between the first material guide roller group and the second material guide roller group, the number of the scalding devices is at least 2, and the at least 2 scalding devices are horizontally spaced, and adjacent to each other. A combing barrel is arranged between the scalding devices, and the scalding devices all include an upper scalding component, a lower support plate and a cooling roller group. The upper scalding component includes a heating rod which can be adjusted up and down and is arranged above the fabric, and a temperature sensor fixed on one side of the heating rod. The lower support plate is located below the fabric, and the upper surface of the lower support plate is against the lower surface of the fabric. The cooling roller group is located on the rear side of the upper support plate. The third guide roller group is vertically arranged below the second guide roller group. The cleaning device is arranged on one side of the third guide roller group. The cleaning device can process the fluff on the upper surface of the fabric after being burnt, and the third guide roller can conduct the fabric toward the outlet direction.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The equipment provided by the present invention is specially used for the production of cashmere fabrics. Since the fabrics only need to be processed on the wool side, the equipment only has a single-sided ironing and shearing function. Specifically: by setting at least two ironing devices, under the condition of the same temperature, the distance between the heating rods on the two ironing devices and the fabric is controlled, and the long hair on the fabric is first ironed by the first ironing device. In this way, after the long hair is processed first, interference with the short hair when the second and subsequent ironing devices are ironed is avoided, thereby improving the quality of ironing and shearing, and the first ironing device can play a preheating role to avoid the hair from curling due to excessively high temperature at one time, and a combing barrel is also provided between adjacent ironing devices, which can comb and clean the fabric in time, thereby effectively ensuring the quality of ironing and shearing, avoiding excessive damage to the hair, and through temperature control and fabric conveying speed control, the length of the hair can be effectively controlled, thereby ensuring the color fastness effect of subsequent dyeing.

[0023] As an improvement, the cross-sectional shape of the combing barrel is trumpet-shaped, the small end of the trumpet is the inlet of the fabric, the large end of the trumpet is the outlet of the fabric, the width of the combing barrel is greater than the width of the fabric, and comb teeth that can comb the fluff on the upper surface of the fabric are provided on the top surface of the trumpet-shaped small end. In this way, the wool surface of the fabric is combed by the comb teeth to prevent the long hair after burnt from being broken up and clumping, thereby ensuring the effect of the subsequent cleaning device.

[0024] As an improvement, an ash collecting pool is provided under the combing barrel to prevent a portion of the ash from falling and ensure the production environment.

[0025] As an improvement, the number of scalding devices is 3, and the distance between the heating rods and the fabric in each scalding device gradually decreases along the fabric conveying direction. In this way, the scalding quality can be improved through the step-by-step scalding method.

[0026] As an improvement, the dust cleaning device includes a cleaning roller, a cleaning brush fixed on the outer layer of the cleaning roller, and an ash suction mechanism arranged under the cleaning roller. The cleaning roller is connected to a motor that can drive the cleaning roller to rotate. In this way, the structure is simple, and the cleaning roller drives multiple cleaning brushes on the outer layer to clean the fabric, thereby sweeping away the ashes. Moreover, since the third material guide roller group is located directly below the second material guide roller group, the ashes can fall accurately and steadily under the action of gravity and suction.
