In the actual production process, the moisture-absorbing and quick-drying filaments of 75D36F are twisted again by twisting equipment to form functional yarns with the moisture-absorbing and quick-drying functions, the twisted functional yarns are woven by a 34 inch 28-needle large round machine according to the bird's eye cloth process to form the embryonic cloth, so that the embryonic cloth has the moisture-absorbing and quick-drying functions, and the integral surface hardness is higher, so that the embryonic cloth is not easy to form a yarn hooking problem before entering a finished product for shaping, meanwhile, the conveying stability is better in the subsequent processing process, the coloring stability is higher during dyeing, particularly, the embryonic cloth is placed in a dye vat, water is heated to 80-90 ℃ by the dye vat and is kept for 20-30 minutes, and after the embryonic cloth is overturned by the dye vat, the embryonic cloth can be cleaned to reach the preshrinking width, and the dyeing effect of the subsequent dyeing is improved. The temperature is controlled between 170 ℃ and 190 ℃ to stabilize the gate gram weight of the fabric, prevent the fabric from causing excessive warp density and weft density change in the subsequent processing, and simultaneously, the speed is 25-30 m/min, and the overfeeding is 3-5% to prevent the fabric from causing style change due to natural stretching in the finished product shaping process, so that the fabric has better stability before and after shaping. In order to avoid the technical problem, the high-temperature high-pressure jet dyeing machine is adopted for dyeing, and the dye for dyeing is the high-temperature type disperse dye, and the high-temperature type disperse dye is jetted onto the functional yarn for dyeing through the high-temperature high-pressure jet dyeing machine, so that the dye can be soaked into the twisted functional yarn more quickly, the time required by the dyeing process is shorter, the internal dyeing effect is better, and the stability is higher. When the dyed embryo cloth enters a finished product shaping machine for shaping after dewatering and slitting, firstly, an moisture absorption quick-drying auxiliary agent is added into a groove through a padder at the front end of a shaping process, wherein the dosage of the moisture absorption quick-drying auxiliary agent is 20-50 g/L, the liquid carrying rate of the embryo cloth when entering shaping equipment is controlled to be 65-75%, the moisture absorption quick-drying auxiliary agent can be better kept in the functional yarn in the shaping process at the speed of 30m/min at 160-170 ℃, so that the functional yarn with the moisture absorption quick-drying function can further improve the moisture absorption quick-drying function, the moisture absorption quick-drying effect of the bird eye cloth is better, meanwhile, the overfeed quantity of 0-15% is matched, the overfeed percentage is generally within 5% due to the relatively higher hardness of the functional yarn after twisting, the overfeed quantity required is smaller, the stability is higher during processing, and the bird eye cloth formed by the method can obtain good moisture absorption quick-drying and silk-preventing effects and is more suitable for being taken as a sports fabric.
In the step of S2 desizing preshrinking, an oil removing agent is added into the dye vat, and the ratio of the oil removing agent to water is 1-2g/L.
In the desizing preshrinking step, in order to better clean grease and stains on the surface of the embryonic cloth, an oil removing agent is generally added into a dye vat, the proportion of the oil removing agent to water is 1-2g/L, and after the oil removing agent is added, the cleanliness of the embryonic cloth after cleaning can be higher, and the coloring is more uniform.
Further improves that the dyeing temperature in the S5 dyeing is 125-135 ℃, the bath ratio of the cloth weight to water is 1:10-15, the dyeing time is 3-5 hours, and 0.2-0.4g/L of terylene high temperature leveling agent DS-2835 and 0.2-0.4g/L of oligomer dispersing agent D1 are added according to the water consumption; and the pH value of the dye liquor in the S5 dyeing is regulated to 4.2-4.6 by using a complex acid.
In the high-temperature high-pressure jet dyeing process, the dyeing temperature is controlled at 125-135 ℃ and the dyeing liquid with the bath ratio of 1:10-15 is matched, so that the dyeing effect of the gray fabric is better, especially when the PH value in the dyeing liquid is regulated to 4.2-4.6 by using the complex acid, the PH value of the fabric before and after dyeing is stable and higher, the color accuracy during high-temperature dyeing can be improved, and the dyeing is more uniform and meanwhile, the polymerization of the oligomer is avoided by adding 0.2-0.4g/L of terylene high-temperature leveling agent DS-2835 and 0.2-0.4g/L of oligomer dispersing agent D1 according to the water consumption.
And the method is further improved in that the softener with the dosage of 0.5-1g/L is added into the dye liquor of the dyeing machine in the S5 dyeing.
The method has the advantages that the whole surface hardness of the blank cloth is higher, although the problem of softness can be solved by adding enough softener before shaping of a finished product, the dyeing difficulty and the stability of conveying the blank cloth are easily caused during manufacturing, the tension control difficulty of each area is increased, the problem of low dyeing efficiency caused by too high rigidity of the blank cloth during dyeing is easily caused, and therefore, when dyeing, the softener with the dosage of 0.5-1g/L is added into dye liquor of a dyeing machine, after preliminary softening is carried out through the softener, the blank cloth can be ensured to have enough softness during dyeing, so that the dyeing efficiency is improved, and the problem of forming difficulty improvement caused by too high softness of the blank cloth can be avoided.
Further improved, the shaping temperature of the finished product in the step S7 is 160 ℃, the time is 30min, and 30g/L of moisture absorption quick-drying agent is matched; and 20g/L of hydrophilic quick-drying softener is also added in the shaping of the finished product in the step S7.
Although the functional yarn is twisted and formed by adopting the moisture-absorbing and quick-drying filaments, the moisture-absorbing and quick-drying effects of the filaments are limited by the materials, so that in order to better improve the moisture-absorbing and quick-drying effects of the finished product of the bird's eye cloth, 30g/L of moisture-absorbing and quick-drying agent is matched in the final finished product shaping, the moisture-absorbing and quick-drying effects of the bird's eye cloth are better, the clothing has excellent moisture-absorbing and quick-drying functions in the early stage, the washable times are more, and especially after the clothing is washed for many times, the bird's eye cloth has good moisture-absorbing and quick-drying effects by the residual moisture-absorbing and quick-drying agent and the performance of the functional yarn, so that the user wears the bird's eye cloth more comfortably. Because the moisture-absorbing and quick-drying filament of 75D36F has the problems of higher rigidity and higher hardness after twisting again, the problem of poor softness after weaving into the bird's eye cloth is caused, compared with the conventional fabric, the bird's eye cloth is harder, so that in order to solve the problem that the bird's eye cloth has too high hardness due to too high rigidity of functional yarns, the hydrophilic quick-drying softening agent is added after the shaping of a finished product, the rigidity and shaping of the embryo cloth can be ensured, the production process is prevented from being influenced, the softness of the fabric can be obviously improved after the shaping of the embryo cloth, the bird's eye cloth can meet the required softness requirement, and the softening agents are respectively added through two procedures, so that the softness of the embryo cloth is better, and the production time required in the shaping process of the finished product is shorter.
Further improved is that the pre-shaping temperature in the step S4 is 180 ℃, the speed is 30m/min, and positive overfeeding is carried out for 3%.
The problem that the fabric is serious in deformation easily caused by overhigh temperature during pre-shaping, and the problem that the warp density and weft density of the fabric are changed easily caused by overhigh temperature during high-temperature dyeing is solved, so that the pre-shaping temperature is controlled to be about 180 ℃, the temperature can stabilize the width of cloth gram weight of the fabric, the problem that the fabric is excessively changed in warp density and weft density during subsequent processing is prevented, meanwhile, the speed is 30m/min, and the positive overfeeding is matched with 3%, so that the fabric is prevented from being changed in style due to natural stretching in the shaping process of a finished product, and the stability of the fabric is better before and after shaping.
The bird's eye cloth manufactured by the method is as follows:
the method comprises the steps of selecting 75D36F moisture-absorbing and quick-drying yarn, twisting S650, twisting to obtain a functional yarn, weaving the functional yarn by a 34 inch 28-needle large round machine according to a bird' S eye cloth process, carrying out desizing preshrinking on the embryo cloth by a dye vat after unwinding, keeping the temperature at 80 ℃, keeping the temperature for 30 minutes, enabling the consumption of a degreasing agent to be 2g/L, carrying out dehydration and slitting, carrying out presetting, enabling the presetting temperature to be 180 ℃, enabling the speed of a vehicle to be 25M/MIN, overfeeding to be 5, spraying high-temperature disperse dye on the embryo cloth by an overflow dyeing machine entering high temperature and high pressure, and carrying out dyeing on the embryo cloth, wherein the dyeing temperature of the embryo cloth is 130 ℃ and the bath ratio of 1:15, dyeing for 4 hours, adding 0.5g/L of high-temperature leveling agent, 0.3g/L of oligomer dispersing agent and 0.1g/L of softening agent into the dye liquor, dehydrating again to form a finished product, overfeeding 3% at 160 ℃, and using 50g/L of moisture-absorbing and quick-drying agent and 20g/L of hydrophilic quick-drying softening agent as auxiliary agents. The method can obtain the anti-hooking moisture-absorbing quick-drying bird eye cloth, and various strength is superior to that of the conventional bird eye cloth. The test results of the finished products are shown in Table 1.

the embryo cloth is selected from 75D72F moisture-absorbing and quick-drying yarn, but the bird's eye cloth which is not twisted again is as follows:
the method comprises the steps of selecting 75D72F moisture-absorbing quick-drying filaments for the gray fabric, weaving the filaments by a 34 inch 28 needle large round machine according to a bird's eye fabric process, unreeling, and spraying high-temperature disperse dye onto the gray fabric for dyeing in a high-temperature and high-pressure overflow dyeing machine, wherein the dyeing temperature of the gray fabric is 132 ℃, and the bath ratio is 1:15, dyeing for 4 hours, adding 0.5g/L of high-temperature leveling agent, 0.3g/L of oligomer dispersing agent and 1g/L of softening agent into the dye liquor, dehydrating again to form a finished product, overfeeding 5% at 170 ℃, and using 30g/L of moisture-absorbing quick-drying agent as auxiliary agent. The method can obtain the bird's eye fabric with soft hand feeling, and the moisture absorption and quick drying functions are superior to those of the conventional moisture absorption and quick drying bird's eye fabric. The test results of the finished products are shown in Table 2.
Table 2:
as can be seen from tables 1 and 2, the conventional bird's eye cloth for obtaining the moisture absorption and quick drying functional effect is usually realized by adding the moisture absorption and quick drying auxiliary agent in a dye vat or in the shaping process, and the moisture absorption and quick drying effect obtained by the method is obviously deteriorated after multiple times of washing, which is not in line with the actual situation that the summer sportswear needs frequent washing. The bird's eye fabric woven by the moisture absorption and quick drying functional yarns is finished and added with the moisture absorption and quick drying auxiliary agent, so that the fabric has better functional effect and durability. Meanwhile, the common yarn hooking condition of the conventional bird's eye cloth is achieved by adopting twisted yarns for weaving, the moisture absorption quick-drying performance of the conventional bird's eye cloth is slightly reduced, but the moisture absorption quick-drying function is close, the effect is more durable, the strength is better, the cohesion between yarns is stronger, the yarn hooking prevention capability of the fabric can be obviously improved, the yarn hooking prevention capability is better, and meanwhile, all strong indexes are also improved.
The above embodiments are only preferred embodiments of the present application, and the scope of the present application is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present application are intended to be within the scope of the present application.
