Detailed Description
Example 1
In the method for dyeing and finishing the sweater and pants in the embodiment, the sweater and pants adopt 21SThe C/150D French rib fabric is woven, and the required color is pine branch green.
The fabric is dyed by the following dyes, ingredients and auxiliaries:
the dyeing process comprises the following steps:
putting water into the dyeing machine according to the amount of the cotton knitted fabric pretreated in the dyeing machine and a preset bath ratio;
heating the water to 40 ℃;
adding 80g/L of anhydrous sodium sulphate, 1g/L of leveling agent and 5g/L of soda ash into water in a circulating injection mode within 5 minutes, and preserving heat for 15 minutes at 40 ℃;
quantitatively adding all dyes into a dyeing machine within a set time by using the function provided by equipment in a 15-minute time quantitative manner (the quantitative manner in the invention refers to that all the dyes are automatically and linearly added by the equipment in the set time, the same is carried out below), and then, preserving the temperature for 20 minutes at 40 ℃;
adding 15g/L20 min alkali into a dyeing machine for 20 min, and then preserving heat for 20 min;
heating to 60 deg.C at a rate of 1 deg.C/min for 20 min, and holding for 50 min;
discharging residual liquid in the dyeing machine.
In the process, pine branch green is dark, and common dyes and processes cannot be achieved, so the dye structure in the formula is relatively complicated, and the dye structure comprises monochlorotriazine and vinyl sulfone double-active-group active red S-B, active yellow S-3R, monofluorotriazine and improved vinyl sulfone double-active deep blue S-GL, and Lihuashi CA blue containing two monofluoros-triazines. Because the possibility that the product generates color flower and color difference is higher as the compatibility difference of the dye is larger as the color matching is more adopted, a pre-saline-alkali adding process with strict requirements is used, and good results are obtained. When dyeing and washing, the used equipment is a high-temperature high-pressure horizontal long-tube overflow dyeing machine for producing the style of the fabric. After the treatment of the process, the washing fastness, the dry rubbing fastness, the wet rubbing fastness and the light fastness of the fabric are tested to be over 5 grades.
The process passes through 1800 tons and 20 tonsSIn the actual production of C/150 French ribs, the color correction rate during production is only 2%.
In the above embodiments, after the dyeing process is completed, post-treatment is preferably performed, for example, the following process may be performed:
discharging residual liquid according to the proportion of 1: 8, feeding water according to the bath ratio, washing for 10 minutes at normal temperature, and discharging residual liquid;
according to the following steps: 8, adding 1.5ml/l of diluted neutralization acid into water according to the bath ratio, heating to 50 ℃, neutralizing for 10 minutes, and discharging residual liquid;
according to the following steps: 8, adding 2g/l of the melted soap liquid into water, heating to 95 ℃, soap boiling for 20 minutes, cooling to 80 ℃, and discharging liquid;
according to the following steps: 8, heating the bath ratio to 80 ℃ by feeding water, washing with hot water for 15 minutes, and discharging residual liquid;
according to the following steps: 8, heating the bath ratio of water to 60 ℃, washing with warm water for 10 minutes, and discharging residual liquid;
according to the following steps: 8, heating the bath ratio of water to 40 ℃, adding 1.5g/l of color fixing agent, fixing color for 20 minutes at 40 ℃, and discharging residual liquid.
Example 2
This example is a further treatment on the basis of example 1.
In the traditional dye vat water bath softening method, the hydrophilic softening agent is dissolved in water and does not fully adhere to and permeate into the fabric, so that the effect is very poor, the hand feeling is rough, the elastic recovery rate of the fabric is not high, and the cost is high.
The softness making of the embodiment is that softness is made on a setting machine: the rolling groove of the setting machine is about 80L-100L, the dosage of the nonionic hydrophilic softening agent is 15g/L +/-1, the liquid carrying rate is 90-100%, the setting vehicle speed is 20 m/min, the overfeeding is 20-25% for setting according to the following process conditions, and the setting temperature is set to be 180-183 ℃. The method can soften and shape and reduce the working procedures at the same time, thereby improving the labor efficiency.
The non-ionic hydrophilic softening agent selected in the process can effectively prevent color change; meanwhile, due to the excellent hydrophilicity, the subsequent French rib and the Tyda cotton have higher bonding fastness and soft and smooth commonness, and the friction force between fibers is reduced, so that the subsequent French rib and the Tyda cotton can retract due to widening after being compounded, and the style like a sweater product is generated.
In the process, the overfeeding is 20-25 percent, aiming at fully shrinking polyester yarns in the fabric at high temperature to drive cotton threads to be gathered under the state of no longitudinal and transverse tension, the overfeeding is too small to meet the shrinkage requirement, and the overfeeding too large fabric is likely to contact with a lower blowing port of a setting machine to cause local overheating or yarn hanging phenomenon.
As is well known, 20SIn the high temperature stage of 160-210 ℃ of polyester yarn in C/150D French rib, macromolecules in the fiber gradually obtain the energy of thermal motion, the constraint among molecules is gradually reduced, the macromolecules can slip, dislocate and curl, the elastic modulus of the fiber is rapidly reduced, the deformation capability is increased, the fabric shrinkage is increased, the elasticity and fatigue resistance of the fiber are obviously reduced along with the temperature rise, and the hardness and fatigue resistance of the fiber are obviously reducedThe stiffness is increased. Setting temperature is set to be over-high, 20SThe elasticity of the polyester silk part in the C/150D French rib is low, the hardness and the rigidity are increased, the force for widening to a preset breadth is increased when the Tyda cotton is compounded, and a needle plate of a widening machine is easy to damage or the grey cloth is torn. If the set setting temperature is too low, 20SThe polyester filament part in the C/150D French rib is in a high-elastic state, the force for widening to a preset width is reduced when the Tyda cotton is compounded, the resilience force of the fabric compounded with the Tyda cotton is insufficient, and the resilience cannot reach the preset width, so that the Tyda cotton is exposed in the gaps of ridges. The inventor sets the setting temperature at 180 ℃ plus 3 ℃ and the vehicle speed at 20m/mim through a large number of tests; the setting temperature and the vehicle speed complement each other, so that the resilience of the fabric compounded with the tada cotton is ensured, and the phenomenon that a needle plate of a width support machine is damaged by pulling or the grey cloth is torn due to the increase of hardness and rigidity is avoided. The setting process is 20SThe elastic recovery rate of the C/150D composite Tyda cotton is guaranteed, and the composite Tyda cotton has the characteristics of simplicity, easy control, strong extensibility, high reproducibility and the like
