Description
Technical Field
The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of an antistatic fabric.
Background
However, because the moisture absorption of the polyester fiber is relatively poor and the electric charges accumulated on the surface of the polyester fiber are not easily dispersed, the antistatic effect of the polyester fiber is relatively poor, particularly in winter or in dry weather, the static phenomenon is more intense, and the wearing comfort of consumers is seriously influenced.
At present, two main antistatic treatment modes for polyester fabrics at home and abroad are as follows: firstly, when the static charge is generated, the generation of the static charge is immediately inhibited; secondly, the dissipation of static charge is accelerated so as to realize the antistatic aim of the polyester fabric. At present, the mode of improving the antistatic effect of the terylene in the industry is mainly 1. During weaving, the terylene is blended and woven with other antistatic material materials, such as carbon yarn, but the antistatic material has higher rigidity and is easy to break in after finishing operation, so that the abnormal occurrence of poor cloth cover is caused. 2. The mode of adding the antistatic auxiliary agent is adopted to achieve the antistatic effect during shaping water splashing, the mode is the most used mode in the industry at present, but the defect is obvious, the antistatic auxiliary agent contains a large number of hydrophilic groups, the surface tension of the fabric can be increased, the water splashing effect of the water splashing agent can be further influenced, and the water splashing degree can hardly reach 3 grades (test standard ISO 4920) when the antistatic auxiliary agent is added. The water splashing degree is an important physical property index in the existing chemical fiber fabric after finishing, and particularly in sports and leisure products or outdoor sports products, the requirement is high and is at least 3 grades or above. 3. In the spinning stage, the antistatic material is directly coated by the terylene, so that the problem of poor cloth cover caused by the breakage of the antistatic material in the later process can be solved, the antistatic yarn is coated in the terylene, the water splashing degree cannot be greatly influenced, and the antistatic effect is greatly reduced because the antistatic yarn is coated in the terylene.

Further, in the eighth step, the setting temperature of the setting machine is 160-170 ℃, the speed is 40-50 m/min, the width is 147-150 cm, and the overfeeding is 1-3%.
Furthermore, in the sixth step, the content of the penetrating agent is 20-30g/l, and the content of the antistatic auxiliary agent is 30-40g/l.
Further, in the sixth step, the setting temperature is 120-130 ℃, the setting speed is 25-30 m/min, the width is the original width, and the overfeeding is 1%.
By adopting the scheme, the dyeing and finishing process of the antistatic fabric comprises the steps of coating the antistatic yarn by the terylene and carrying out minimally invasive treatment on the surface of the terylene to expose the antistatic yarn slightly, so that the antistatic effect is improved, the original yarn is antistatic and does not contain hydrophilic groups, so that the water splashing effect is not influenced, and the water splashing degree of the fabric is improved by combining the two-dipping and two-rolling processes.
Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
The invention discloses a dyeing and finishing process of an antistatic fabric, which comprises the following steps:
step one, throwing a blank: the grey cloth is made of polyester core-spun yarn, and the core is carbon yarn.
Step two, desizing: and (4) desizing the grey cloth by a desizing machine.
Step three, dyeing: and (4) placing the desized cloth into an overflow dyeing vat for overflow dyeing.
Step four, washing for one time: and washing the dyed cloth with water to remove residual dye.
Step five, drying: and drying the washed fabric.
Step six, shaping: and (5) shaping the dried cloth by a shaping machine. The penetrating agent selected for shaping is Isopropanol (IPA) or penetrating agent with the same penetrating effect, and the proportion of the penetrating agent is 20-30g/l; quaternary ammonium salt is preferably selected as the antistatic auxiliary agent, and the proportion of the antistatic auxiliary agent is 30-40g/l; the quaternary ammonium salt antistatic agent has weak acidity in water and generates hydrochloric acid-like substances, so that the quaternary ammonium salt antistatic agent can slightly react with terylene, micro holes are drilled on the surface of the terylene, electrostatic yarns can slightly leak out of the terylene, and the holes are very small and cannot be seen by naked eyes, so that the appearance quality cannot be influenced, the dissipation of electrostatic charges can be accelerated, and the antistatic effect can be efficiently improved. The setting speed is 25m/min-30m/min, the setting speed is not too fast, and on the basis of ensuring the production efficiency, the naked effect of the electrostatic yarn can be ensured, and the quality of the cloth cover can be ensured.
Step seven, secondary water washing: by means of the mode of enhancing water washing, the residual quaternary ammonium salt antistatic auxiliary agent in the shaping process is removed, and the influence on the subsequent water splashing effect is avoided. The antistatic auxiliary agent has more hydrophilic groups and larger surface tension, so the antistatic auxiliary agent can conflict with a water splashing agent and reduce the water splashing effect of the fabric, and the process plays a key role in the improvement of the subsequent water splashing degree. Moreover, through the mode of strengthening the washing, can get rid of because of the dyestuff sublimation that produces when the design process is stereotyped, avoid the influence of dyestuff to next process when promoting the colour fastness.
Step eight, water is poured for shaping, and the additive ratio is as follows: 30g/l-40g/l of penetrant; 5g/l-10g/l of bridging agent; 40g/l-60g/l of water splashing agent; the setting conditions are as follows: the temperature is 160-170 ℃, the speed is 40-50 m/min, the width is 147-150 cm, and the overfeeding is 1-3%. Wherein the penetrant is IPA or penetrant with the same penetrating effect. The bridging agent is melamine type bridging agent, and the bridging agent has good effect and is beneficial to the effect of water splashing after washing. In the shaping process of the sixth step, the surface of the terylene is minimally invasive, so that the effect of absorbing the water splashing auxiliary agent in the process is weakened to a certain extent, and the operation of two-dipping and two-rolling is adopted in the water splashing shaping process, so that the liquid absorption rate of the terylene is improved, and the water splashing effect of the fabric is ensured. If the operation is simply carried out in a soaking and rolling mode, the water splashing effect is relatively unstable.
And finally, detecting a finished product.
According to the dyeing and finishing process of the antistatic fabric, the antistatic yarn is coated by the polyester, and the surface of the polyester is subjected to minimally invasive treatment, so that the antistatic yarn is slightly exposed, the antistatic effect is improved, the raw yarn is antistatic and does not contain hydrophilic groups, the water splashing effect is not influenced, and the water splashing degree of the fabric is improved by combining the two-dipping and two-rolling processes.
The above embodiments are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should be considered as not departing from the scope of the present invention.
