The rib fabric woven by the strong twisted yarns has better elastic resilience because the twist of the strong twisted yarns is larger during spinning and the cotton fibers are excessively twisted and deformed, and has better ductility than common twist varieties in a state of being stretched by external force. The produced rib fabric, namely rib fabric, is subjected to liquid ammonia finishing, liquid ammonia micromolecules below minus 34 ℃ instantly permeate into cotton fibers, the crystallinity of the cotton fibers is changed, cellulose molecules are rearranged, natural distortion of the cotton fibers is reduced, the yarns are uniform in thickness, the dynamic friction coefficient between the yarns is reduced, and the resistance borne by the fabrics during rebound is reduced, so that the elastic resilience and the shape retention of ribs after liquid ammonia finishing are obviously improved. In addition, the liquid ammonia finishing can eliminate the internal stress of the fiber, increase the toughness and the strength and improve the wear resistance of the fabric, so that the problem that the color of the dark-color rib fabric turns white and fades after washing can be solved. The rib fabric produced by the manufacturing method of the embodiment has good elastic recovery and shape retention, is more durable and durable, and has good durability.

In order to ensure that the fabric has enough reaction time after being padded with liquid ammonia, the speed of the vehicle cannot be too fast, but the speed of the vehicle cannot be too low, and the production efficiency is influenced due to too low speed, when the speed of the liquid ammonia finishing vehicle is 10-20m/min, the elastic recovery rate is ensured, and the production efficiency is also considered. The tension of the grey cloth feeding blanket in the liquid ammonia finishing is 4-5kg, and the tension of the grey cloth discharging blanket in the liquid ammonia finishing is 5-6 kg. The cloth feeding blanket tension and the cloth discharging blanket tension are related to the speed of liquid ammonia processing, and are also related to the cloth surface tension before and after the fabric liquid ammonia processing, a lower speed corresponds to a larger tension, and a higher speed corresponds to a smaller tension.

The concentration of polyurethane is 30-60g/L, the concentration of softening agent is 10-50g/L, the concentration of penetrating agent is 1-3/L, and the temperature of tentering and setting is 150-170 ℃. The speed of tentering and setting is 10-30 m/min.
When tentering and setting are carried out, a softening agent and a penetrating agent are generally added in tentering and setting of common fabrics, the speed is generally 30-60m/min, and the temperature is 130-150 ℃.
This application is at first when tentering is stereotyped, adds polyurethane, and polyurethane itself has better elasticity, has certain help to improving rib fabric elastic recovery.

During boiling-off operation, 1-2g/L of caustic soda, 0.5-1.5g/L of hydrogen peroxide and 1-2g/L of refining agent are added, the mixture is kept for 30-60 minutes at 95-100 ℃, and the grey cloth is washed to be neutral (pH: 6-8) by acetic acid after the boiling-off operation treatment.
S6 enzyme washing: and (4) carrying out enzyme washing operation on the boiled grey cloth. During the enzyme washing operation, 1-3g/L cellulase and 1-2g/L acetic acid are added and the mixture is kept at 45-55 ℃ for 40-50 minutes. Wherein acetic acid is used to adjust the pH to 5-6.
S7 setting dry cloth: and (4) squeezing the enzyme-washed grey cloth on a setting machine, and drying. When setting the dry cloth, the temperature is 130-160 ℃, and the speed is 20-40 m/min.
S8 staining: the grey cloth after the shaping and drying is dyed into the required color by reactive dyes according to a certain formula, and soaping and washing are carried out after dyeing to wash off the loose color.
S9 tentering and setting: and (4) performing tentering setting operation on the grey cloth finished by the liquid ammonia.
Tentering and setting: adding softening agent and penetrant. The concentration of the softening agent is 10-50g/L, the concentration of the penetrating agent is 1-3/L, and the temperature of tentering and setting is 130-150 ℃. The speed of tentering and setting is 30-60 m/min.
S10 preshrinking: pre-shrinking the stentering and sizing grey cloth on a rubber blanket of a pre-shrinking machine, and controlling the shrinkage of the grey cloth to be between-5 and 0.
And S11, checking of finished products: and (5) inspecting the appearance quality and the internal quality index of the preshrinked grey cloth.
The process combinations of the 9 groups of examples of the present application were used to produce rib fabrics respectively and rib fabrics produced by the traditional process (the traditional process is the process of the comparative example), the comparison test of key indexes resulted in the following results:
as can be seen from the test results in the above table, the rib fabric produced by the 9 processes of this embodiment greatly improves the elastic recovery and shape retention, and is more durable and durable compared with the conventional process. The flatness and color change of the washed appearance are obviously better than those of the traditional process.
Analysis and test results show that 1400TPM is superior to 1300TPM and 1300TPM is superior to 1200TPM in the improvement of the yarn twist to the elastic recovery rate, but the rib fabric of 1400TPM is closer to the rib fabric of 1300TPM, and the rib fabric of 1400TPM is hard and astringent in hand feeling, so that the rib fabric with the twist of 1300TPM is selected by comprehensively considering the hand feeling and the elastic recovery.
The improvement in elastic recovery by the liquid ammonia process, from good to relatively bad, is, in order, example 1> example 2> example 3, example 4> example 5> example 6, example 7> example 8> example 9. Taking three embodiments of 1200TPM groups as an example, wherein embodiment 1 and embodiment 2 are relatively close, but the liquid ammonia process corresponding to embodiment 2 is selected because the production efficiency is affected due to the low vehicle speed corresponding to embodiment 1. The other two groups of examples select examples 5 and 8.
From the viewpoint of combining the results of all the schemes, the handfeel of the fabric and the production efficiency, the preferred process scheme in 9 groups of examples is example 5.
The rib fabric produced by the manufacturing method has good elastic recovery, shape retention and durability, and the problems of multiple fading and whitening of the rib fabric after washing are greatly improved. For example, the rib fabric manufactured by the application is taken to make the collar and part of the cuff of the knitted T-shirt. After the knitted T-shirt is worn for a long time and pulled and washed for many times, the collar and the cuffs of the knitted T-shirt are not loosened and deformed, and are not wavy or have scalloped edges, so that the knitted T-shirt still has good elasticity and extensibility, and even if the knitted T-shirt is dark-colored clothes, the knitted T-shirt still has the color which is more consistent with the original clothes after being washed for many times.
The present application has been described with reference to specific examples, which are provided only to aid understanding of the present application and are not intended to limit the present application. For a person skilled in the art to which the application pertains, several simple deductions, modifications or substitutions may be made according to the idea of the application.
