Plain woven fabrics are highly popular with consumers due to their good air permeability and durability, but because plain woven fabrics have warps and wefts interlaced once every other yarn, the number of interlacing points is the largest, the number of yarn buckling points is the largest, and thus fabric shrinkage is one of the quality difficulties. In addition, the plain weave fabric has the difficulties of easy combing and slippage of warp and weft yarns in production and processing, and is particularly more obvious on high count thin fabrics, such as voile fabrics and the like.
Based on the advantages of plain woven fabrics and the difficulties to be solved by production and processing, the plain woven fabrics comprise external and internal indexes such as combing crack, slippage, shrinkage rate and the like. The careless split problem has the most serious influence, and the careless split fabric can cause the problems of unclear pattern outline, deformation, different local color depth of the fabric and the like after printing and dyeing, and directly causes the unqualified external index of the finished fabric. The slippage index is too poor, and can be gradually exposed in the sewing, embroidering and using processes after being purchased by consumers, thereby bringing great influence to products. Therefore, the plain weave fabric needs to be deeply explored and creatively improved in each link of the weaving, dyeing and finishing processing technology, and the purposes of not influencing the appearance style of the fabric and enabling the internal indexes to be qualified are achieved.

Detailed Description
The technical solution of the present invention will be further explained with reference to the specific embodiments.
The dyeing and finishing processing method of the plain weave fabric, provided by the invention, sequentially carries out the working procedures of singeing, pretreatment, mercerizing, whitening and stentering, printing or dyeing, color fixation, washing, pretreatment, calendaring, after-finishing and shaping, and preshrinking on gray fabric.
Wherein, the pretreatment adopts an overflow machine or a cold-heaping mode, which can ensure that the warp-wise tension of the fabric is small. The overflow machine or the cold accumulation equipment is not provided with a pressure roller, an expanding roller and other devices with high tension and pressure, so that the fabric yarn arrangement is not influenced, and the fabric combing phenomenon is avoided, thereby avoiding printing and dyeing defects of the fabric in the printing and dyeing process. The calendering process adopts a rubber roller calender, is different from the conventional calendering equipment and comprises a cooling device, as shown in figure 1, the cooling device comprises one or more metal cylinders, and heat absorption cool gel is filled in the metal cylinders; and (4) directly passing the calendered fabric through a cooling device, and then cropping to prepare for the next working procedure.
The invention creatively utilizes overflow or loose processing equipment with relatively small tension to solve the problems of unclear pattern outline, deformation, different local color depth of the fabric and the like after printing and dyeing due to the combing phenomenon caused by overlarge warp and weft stress in the fabric processing process, and directly causes unqualified external indexes of the finished fabric. Meanwhile, the fabric is finished by adopting loose after-finishing, and the finishing effect is improved by matching with an elastic rubber roller calender. The rubber roller calender can effectively reduce the temperature of the fabric under high-temperature calendering to 40-100 ℃ by adding a cooling device, and if the cooling device is not adopted, the temperature of the fabric is raised due to stacking, so that unrecoverable wrinkle marks are easily generated, and the product quality is influenced; the cooling device uses the gel as a heat absorbing medium, can effectively solve the problem that moisture in the air is condensed on the surface of the metal cylinder, and ensures that the fabric cannot cause quality defects due to condensed water. Meanwhile, the fabric slippage index is effectively controlled, and the slippage problem of the sewing thread in the fabric sewing and embroidering process is avoided.
The conduction device of the loose dryer is a polytetrafluoroethylene crawler belt, the fabric is soaked in the working solution and is flatly paved on the net-shaped crawler belt in a wet mode, the fabric is dried through hot air, the drying effect of the fabric is achieved, the fabric is not under the tension effect in the weft direction, and the performance reduction of the fabric caused by the uneven tension can be avoided.
The press roll of the rubber roll calender consists of a metal roll and a rubber roll. Different from conventional metal rollers and nylon roller calenders (three-roller calenders and five-roller calenders), the fabric processed by the elastic rubber roller calenders can obtain better gloss effect, and the rubber roller has good elasticity (the nylon roller belongs to a hard roller and has poor elasticity), so that the auxiliary agent attached to the fabric fiber can generate better reaction, pressure bonding and film forming effects under the conditions of temperature and pressure. The invention utilizes the auxiliary agent evenly attached to the fabric to form bonding between the interweaving points of the warp and weft yarns of the plain weave fabric under the pressure action of the elastic rubber roller calender, so that the bonding force is realized, and the slippage performance between the warp and weft yarns is effectively controlled.
The setting temperature of the after-finishing setting is 110-. The high temperature can increase the internal stress of the fiber, and the shrinkage can be caused to a greater extent after moisture regain and water falling, so that the setting temperature of the plain weave fabric is not too high, and the finishing effect can be achieved; in the setting process, the warp and weft tension of the fabric is not suitable to be large, overfeeding is needed to be carried out in the warp direction, the overfeeding rate is controlled to be +0.0% -5.0%, the fabric width is needed to be set according to the width of a machine on the fabric, and the width expansion rate is controlled to be 4% -6%, so that the fabric shrinkage rate is guaranteed.
In the singeing step, the singeing grade is required to be 4 or more. The grey cloth hairiness is burnt completely, short hairiness exists on the surface of the fabric due to incomplete singeing, the fabric is washed in loose water, the hairiness can be exposed from the inside of the fiber, the fabric appearance effect is affected, meanwhile, the singeing effect is good, and the fuzzing and pilling grade of the fabric can be improved.
The cold-batch process of the pretreatment adopts a desizing, boiling and bleaching one-step method, the working solution of the pretreatment is 10-25g/L of caustic soda (puffing, decomposing and removing slurry), the penetrant is 1-4g/L (wetting and accelerating the working solution to be immersed into the fiber, which is beneficial to desizing), the chelating dispersant is 2-8g/L (increasing the suspension property of impurities in water and avoiding secondary contamination), the refining agent is 2-8g/L (removing fiber impurities and oil agents), the hydrogen peroxide is 6-24g/L (removing colored impurities in the fiber and improving whiteness), and the hydrogen peroxide stabilizer is 3-10g/L (controlling the decomposition rate of the hydrogen peroxide, improving the utilization rate of the hydrogen peroxide and avoiding the generation of oxidation and hole breaking). The liquid carrying amount of the cold reactor is 100-; after the cold batch is finished, cleaning the fabric for 2-3 times by using hot water, wherein the surface of the fabric is required to be clean and has no residue;
the overflow machine procedure of the pretreatment adopts a two-step method: the desizing and refining working solution is 10-25g/L of caustic soda, 1-4g/L of penetrant, 2-8g/L of chelating dispersant and 2-8g/L of refining agent, the temperature is 95-100 ℃, and the processing time is 1-2 hours; bleaching working solution 10-15g/L of caustic soda, 6-24g/L of hydrogen peroxide, 3-10g/L of hydrogen peroxide stabilizer, 80-90 ℃ of temperature and 30-50 minutes of bleaching time.
The mercerizing procedure is suitable for the fabrics containing cellulose fibers, the caustic soda concentration is 80-120g/L, and the mercerizing time is as follows: 70-80 s. Mercerizing is mainly to ensure that the cellulose fiber has fuller color, better color fastness and not too high mercerizing concentration in the dyeing or printing process, and the reason why the plain weave fabric, especially the light and thin fabric, has strong shrinkage caused by high-concentration caustic soda, has extremely strong mercerizing effect, and simultaneously hardens hand feeling, thereby bringing irreparable influence on the slippage and the shrinkage of the fabric;
whitening and tentering, which is generally a previous process for printing fabrics, are not required for dyeing fabrics. Setting the fabric to the required width of printing and dyeing equipment at the temperature of 110-;
printing, dyeing, color fixing and washing are well-known technologies in the field and are not described in detail;
the pretreatment working solution is a mixture of polyurethane and resin, the amount of the polyurethane is 10-30g/L, the amount of the resin is 20-50g/L, and the liquid carrying amount of the fabric is 65-75%. And drying at the drying temperature of 110 ℃ and 130 ℃. The resin finishing agent is a crosslinking auxiliary agent, can promote self-crosslinking or net-shaped crosslinking among molecules, plays a role in fixing the structural form among fibers, and mutually restrains net-shaped crosslinking structures formed among fabric fibers when the resin finishing agent is subjected to a certain external force or washing action. The polyurethane acts as a binder to form bonds between the fabric fibers, thereby stabilizing the yarn structure and reducing slippage between the fibers. The strength of the fabric is reduced when the using amount of the resin is too high, the hand feeling of the fabric is affected when the using amount of the polyurethane is too high, the effect is not good when the polyurethane is used alone, and the effect of the invention can be met when the polyurethane and the fabric are used in combination.
The calender pressure in the calendering process is 5-8kg, and the calendering temperature is 130-150 ℃.
The setting temperature of the post-finishing setting procedure is 110-;
the pre-shrinking process is carried out in a pre-shrinking machine, the pre-shrinking speed is 20-30m/min, and the warp shrinkage rate of the fabric is improved;
