Detailed Description
The present invention will be described in detail with reference to the following embodiments for a full understanding of the objects, features, and effects of the present invention. The process of the present invention is carried out by methods or apparatus conventional in the art, except as described below. The following terms have the meanings commonly understood by those skilled in the art unless otherwise indicated.
Aiming at the problems of poor moisture absorption and moisture conduction effects of the existing bra fabric, the inventor of the invention conducts intensive researches on the aspects of raw material selection, processing process and the like of the bra fabric, thereby creatively providing a preparation method of the bra fabric, and the preparation method can be used for obtaining the bra fabric with excellent moisture absorption and moisture removal effects and quick drying performances.
Specifically, the preparation method of the bra fabric comprises the following steps:
(1) Woven fabric
In the invention, raw materials adopted by the woven fabric comprise nylon fibers, polyester fibers, regenerated cellulose fibers, cotton fibers and spandex.
As a preferred embodiment, the invention adopts the raw materials with the weight percentage as follows: 20-40% of nylon fiber, 20-35% of polyester fiber, 10-20% of regenerated cellulose fiber, 10-20% of cotton fiber and 3-7% of spandex. Among them, the regenerated cellulose fiber is preferably any one of cuprammonium fiber, chitin fiber, bamboo fiber, modal fiber (Modal) and Tencel fiber (Tencel).
In the present invention, the method for weaving the raw materials into the fabric can refer to related schemes in the prior art, and will not be described herein.
(2) Hydrophilic treatment
The fabric may be pretreated prior to hydrophilic treatment, including conventional operations such as washing, rinsing, wringing, and flattening. As an exemplary embodiment, the pretreatment process includes:
(1) cleaning: soaking the fabric in clear water by using a neutral detergent or a professional cleaning agent to remove stains and impurities on the surface;
(2) rinsing: placing the cleaned fabric into clear water for rinsing to ensure that residues such as detergent and the like are completely removed;
(3) squeezing: lightly squeezing the rinsed fabric to ensure that the humidity of the fabric is moderate;
(4) flattening: putting the squeezed fabric into a dryer for flattening treatment, and ensuring the flatness of the fabric.
Of course, in the actual operation process, the person skilled in the art can appropriately adjust the steps according to the needs, and the scheme after adjustment is also included in the invention.
The fabric is pretreated and then is soaked in hydrophilic treatment liquid to be subjected to hydrophilic treatment. As a preferred embodiment, the hydrophilic treatment fluid used in the present invention comprises, in weight percent: 200-10% of polyethylene glycol, 400-20% of polyethylene glycol, 1-3% of acrylic ester acetate, 1-2% of polyacrylamide, 0.5-2% of silane cross-linking agent, 1-2% of ammonia water and the balance of water. Among them, the concentration of ammonia water is preferably 1% to 2% by weight.
The inventor of the present invention comprehensively considers the moisture absorption performance, the moisture permeability, the quick drying performance and the antibacterial performance in determining the composition and the proportioning relation of the hydrophilic treatment liquid. The method comprises the following steps:
moisture absorption properties: the selected components have certain moisture absorption performance, can absorb moisture in the air, and improve the moisture absorption performance of the bra fabric;
moisture transfer performance: the interaction between the components in the hydrophilic treatment liquid can form a hydrophilic layer, so that the moisture conducting performance of the bra fabric is improved, and the bra fabric is prevented from being moist and airtight;
quick-drying performance: the polyacrylamide added into the hydrophilic treatment liquid can improve the quick-drying performance of the bra fabric, so that the bra can quickly remove moisture and sweat;
antibacterial properties: the interaction of the ammonia water solution and other components in the hydrophilic treatment liquid can play a certain role in resisting bacteria, and bacteria breeding in the bra fabric is reduced.
The hydrophilic treatment fluid determined after comprehensively considering various performances has the synergistic effect among the components, and the hydrophilic treatment fluid comprises the following components:
firstly, in terms of specific component selection and proportion optimization, the proportion of polyethylene glycol 200 and polyethylene glycol 400 is selected to realize the synergistic effect of polyethylene glycol with different molecular weights and improve the humidifying capacity of the hydrophilic treatment liquid; the addition of the propylene acetate can improve the dispersibility and stability of the hydrophilic treatment liquid; the addition of the polyacrylamide and the silane crosslinking agent can improve the adhesiveness between the hydrophilic treatment fluid and the surface of the bra fabric and the washing resistance; the addition of the ammonia water solution is beneficial to pretreatment of the bra fabric, and the cleaning and antibacterial effects of the surface of the fabric are realized.
And secondly, the interaction between the components can promote the components to jointly exert the performance of the components to form a hydrophilic layer with more stable and strong effect, thereby realizing high-efficiency moisture absorption, moisture conduction and quick drying performance and a certain antibacterial effect. Finally, these optimized component selections and ratio designs can significantly improve the quality and performance of the bra shell and improve the comfort and health of the user.
Again, the setting of the concentration of the liquid component balances the relationship between the hydrophilic properties and the cost factors to a certain extent and ensures that sufficient active agent or cross-linking agent is involved in the hydrophilic treatment liquid preparation and fabric curing process and the desired fabric properties are ultimately achieved.
In addition, the invention also integrally considers the interaction and promotion relationship between the raw materials and the hydrophilic treatment. Specifically, through the selection and optimization of the composition and the proportion of raw materials and the selection and the optimization of the composition and the proportion of hydrophilic treatment liquid, the hydrophilic treatment liquid can permeate into the fabric in the processing process of the bra fabric, the hydrophilicity of the fabric is increased, and the moisture absorption and drainage performance of the fabric is improved. On the premise of ensuring hydrophilicity and other comprehensive performances, the proportion of raw materials is further optimized, and on the basis of excellent performance fibers such as nylon, terylene and the like, a proper amount of hydrophilic regenerated cellulose fibers, cotton fibers and the like are added, so that the hydrophilicity and the moisture absorption and drainage performances of the bra fabric are effectively enhanced.
When the hydrophilic treatment liquid is prepared, the conditions of agglomeration, difficult dispersion and the like are avoided so as not to influence the quality of the hydrophilic treatment liquid. As a preferred embodiment, the present invention employs the following method for preparing the hydrophilic treatment liquid:
adding a specified amount of polyethylene glycol 200, polyethylene glycol 400 and polyacrylamide into water, and uniformly mixing to obtain a first mixed solution;
adding a prescribed amount of ammonia water into the first mixed solution, and uniformly mixing to obtain a second mixed solution;
and adding a specified amount of propylene acetate and a silane crosslinking agent into the second mixed solution, and uniformly mixing to obtain the hydrophilic treatment solution.
The arrangement of the material adding sequence can avoid the condition that some materials are agglomerated or are difficult to uniformly disperse after water is added, thereby ensuring the preparation quality of the hydrophilic treatment liquid.
When the fabric is soaked in the hydrophilic treatment liquid for hydrophilic treatment, the control of temperature and soaking time should be paid attention to. As a preferred embodiment, the hydrophilic treatment liquid is soaked for 10-30 min at 55-80 ℃.
The inventor finds that the temperature and time of soaking the hydrophilic treatment liquid can influence the permeability and the reaction effect on the fiber. The hydrophilic treatment liquid can be ensured to work at a proper temperature by selecting the temperature of 55-80 ℃, the permeation of the liquid is accelerated, and the treatment effect is improved. The length of the soaking time is mainly dependent on factors such as the type of the treated fiber and the composition of the liquid treating agent, and the shorter time can save energy and the treatment time, but the final effect of hydrophilicity can be affected. The invention can reduce the cost to the minimum while realizing excellent effect by adopting the soaking time of 10-30 min.
(3) Rinsing, drying and curing
The fabric obtained by hydrophilic treatment is rinsed first, for example in clear water or with a detergent. Then, the fabric is put into a dryer containing ammonia water for drying and curing.
In the dryer containing ammonia water, the ammonia water can accelerate the detachment of the molecular size of the fiber surface from the polymer layer, and simultaneously is helpful for the formation of ionic bonds on the fiber surface, thereby improving the affinity of water molecules on the fiber surface. However, too high an ammonia concentration tends to cause corrosion of the fibers and decrease the strength of the fibers, and therefore the ammonia concentration used in the present invention is 1% to 2% by weight. As for the amount of ammonia in the dryer, it can be determined by those skilled in the art according to actual needs.
The drying temperature adopted by the invention is 110-130 ℃ and the time is 10-20 min. The drying process is an ironing process of forming ionic bonds and macromolecular layer size molecules on the fibers by hydrophilic treatment liquid. In the hydrophilic treatment, the temperature and time of drying are also very important parameters, and the higher temperature of 110-130 ℃ and the drying time of 10-20 min are selected, so that the formation of ionic bonds can be promoted, the hydrophilicity of the fiber surface is improved, and meanwhile, the thermal damage and the elastic loss of the fiber caused by overhigh temperature and overlong time can be avoided.
The curing of the fabric can be realized by means of the action of ammonia water and heat in the dryer, and in order to further enhance the curing treatment effect of the fabric, the invention can also add a reagent selected from carbamate, glycol, isopropanol and acetone in the dryer, and the specific addition amount can be determined by a person skilled in the art according to the needs.
After the fabric is cured, the fabric may also be rinsed again and dried to remove the treatment fluid residue. The specific operations of rinsing and drying may be the same as the previous steps or may be adjusted as desired, for example, to more thoroughly clean the fabric to ensure complete removal of the treatment liquor residues, while using better performing detergents, as may be determined by one skilled in the art.
It should be noted that various materials used in the preparation method of the present invention can be obtained by market purchase.
The bra fabric with good moisture absorption and removal effects and excellent quick-drying performance can be prepared by adopting the preparation method provided by the invention, and can be used for preparing the bra, and the specific preparation method can refer to related schemes in the prior art and is not described in detail herein.
