Among them, the most important problem during physical exercise is the management of sweat. If the air permeability of the clothes can be adjusted according to the change of the internal environment of the clothes, namely the change of humidity during the movement of a person, the clothes provide more excellent heat and humidity comfort for the sportsman.
For the function of adjusting the air permeability and comfort of the garment according to the change of the internal environment of the garment, i.e., humidity, there are some products on the market, such as "MRT fiber" developed by the japanese emperor and "Ventcool" developed by mitsubishi corporation of japan. The MRT fiber of the imperial is polyester and polyamide bicomponent fiber, and the yarns are bent due to different expansion and extension degrees of the yarns after moisture absorption due to different shrinkage rates of the two components, so that gaps among the yarns are increased, the air permeability of the fabric is improved, and hot and humid air inside the garment is released; the yarns shrink and the air permeability decreases when dry, thereby providing the heat and moisture comfort of the garment when in motion. The dynamic fiber Ventcool is prepared by adopting a unique fiber modification technology and a composite spinning technology and carrying out composite spinning on strong-hydrophilicity modified diacetate fibers and weak-hydrophilicity triacetate fibers. During drying, the modified diacetate fibers volatilize and shrink, so that the length between the two acetate fibers appears, and the fibers form spiral curls. When the fabric absorbs moisture and is wet, the modified diacetate fibers absorb moisture, swell and stretch, and the air permeability of the fabric is increased. However, the production processes of these two types of yarns are complicated and costly. Therefore, a simple and feasible method for realizing fabric capable of adjusting the air permeability and the comfort of the garment according to the change of the internal environment of the garment, namely humidity is needed to meet the market demand.

The polyurethane material comprises MDI-based polyether polyurethane, wherein MDI is diphenylmethane diisocyanate. In addition to the MDI-based polyether urethane, the raw material of the hygroscopic expansion layer may further include at least one of a small amount of a crosslinking curing agent, an antioxidant, a stabilizer and a lubricant. The polyurethane material is heated, melted and then cross-linked and solidified, and loses the property of hot melt. The cured polyurethane material absorbs water to expand; after drying, the moisture evaporated and the material recovered. Generally, in terms of the structure of the polymer material, two conditions are required for the material to have water-swelling property: one is that the molecular chain contains hydrophilic groups, and the other is lightly crosslinked to form a three-dimensional network structure. The principle of water swelling of the polyurethane material in this example is the ether linkage (-CH) of the polyether segment in the diphenylmethane diisocyanate-based polyether urethane2-CH2-O-CH2-CH2-) has a lone pair of electrons which are not bonded, and can be connected with hydrogen atoms in water molecules to form hydrogen bonds to form a water absorption function. On the other hand, the polyurethane material contains a small amount of cross-linking agent, and when the polyurethane material is heated and melted at 120 ℃ for example, the auxiliary agent can generate bridging cross-linking reaction to form a slightly cross-linked three-dimensional network, so that the polyurethane material can repeatedly absorb water and expand.

As shown in fig. 1, the apparatus for preparing an absorbent shape-changeable fabric of this embodiment includes a heating plate 110, a doctor blade 120 extending along a long side of the heating plate 110, an embossing roll 130, and a fabric transfer roll 140. The edge of the heated plate 110 to which the doctor blade 120 is attached is adjacent the embossing roll 130. The axis of the fabric transfer roll 140 is parallel to the axis of the embossing roll 130 and the fabric 150 is transferred between the fabric transfer roll 140 and the embossing roll 130.

The pattern of the embossing roll 130 may include at least one of dot, line and grid patterns. The dot, line or grid pattern may comprise any shape of cells such as hexagonal, diamond, snowflake, solid dots, oval, and short lines. As an alternative embodiment, the pattern of embossing roll 130 may include at least one of a dispersed hexagonal pattern, a dispersed diamond pattern, a dispersed snowflake pattern, a dispersed circular pattern, a continuous hexagonal pattern, and a continuous snowflake pattern.
Fig. 2 is a flow chart of a method for manufacturing an absorbent deformation fabric according to another embodiment of the present invention.
As shown in FIG. 2, in step S310, a heating plate with a doctor blade on one side is brought close to the embossing roll at a set slope so that the doctor blade abuts the embossing roll, and heating of the heating plate is initiated. As an alternative embodiment, a rectangular heating plate with a scraper on one side is close to an embossing roller of the printing equipment at a certain inclination, the scraper is tightly attached to the embossing roller, and a heating button of the heating plate is turned on to start heating. The heating temperature of the heating plate may be set to 100-.
In step S220, the polyurethane material is placed on a heating plate to be melted. As an alternative embodiment, after the temperature of the heating plate is stabilized, the polyurethane material is placed on the heating plate and melted.
In step S230, the polyurethane material is melted on the heating plate and flows onto the embossing roll, and the polyurethane melt on the non-engraved portion of the embossing roll is scraped off by the scraper, so that the polyurethane melt is left in the concave pattern of the embossing roll.
In step S240, the fabric transfer is started, and when the embossing roller imprints the fabric, the polyurethane melt enters into the cavities or concave-convex parts adhered to the surface of the fabric, and forms mechanical attraction by solidification, thereby generating a binding force. As an alternative embodiment, after the embossing roller is uniformly coated with the polyurethane melt, the fabric conveying roller is started, and when the embossing roller embosses the fabric, the polyurethane melt enters into the cavities or the concave-convex parts adhered to the surface of the fabric, and forms mechanical attraction through solidification, so that the binding force is generated.
And step S250, drying the fabric to obtain the moisture absorption deformation fabric. As an optional implementation mode, the fabric is dried by blowing to obtain the polyurethane printed fabric. And standing the fabric for a set number of days at room temperature so that the polyurethane material is completely crosslinked and cured, and finally preparing the polyurethane printed fabric capable of absorbing moisture, expanding and deforming.
When the printed fabric prepared by the process of the embodiment absorbs moisture, the fabric printed with the pattern is absorbed by moisture and expands to form bulges, and the parts contacting with the body are concave and convex, so that the fabric is not easy to adhere, and the dry and comfortable feeling is kept. Meanwhile, compared with the non-printed fabric, the printed fabric is stretched due to moisture absorption and expansion of the polyurethane, the length of the yarn breathable pipeline is possibly reduced, the breathability of the fabric is increased, moist and hot air in the garment can be released, and the heat-moisture comfortable feeling of the garment is improved; after the fabric is dried and the moisture is volatilized, the fabric is recovered. The moisture absorption deformation fabric substrate fabric has wide selection range, and fabrics of different materials, such as knitted fabrics or woven fabrics of terylene, chinlon, terylene ammonia and nylon ammonia, and fabrics of different tissue structures can be suitable, so that the moisture absorption deformation fabric substrate fabric has better universality. In addition, the polyurethane printed fabric has high washing fastness, and the moisture absorption expansion deformation effect still exists after washing for many times, so that the polyurethane printed fabric has better durability.
The properties of the printed fabrics prepared by the process of the present invention examples are detailed below by several comparative experiments. The experimental procedure used was as follows: after the fabric absorbs water with the same weight of the fabric, namely the water absorption rate is 100%, the weight is weighed in a constant temperature and humidity environment, after the water absorption rate is calculated, the air permeability is measured according to GB/T5453-1997, and the water absorption rate and the air permeability are measured for different times of 30 minutes, 60 minutes, 120 minutes, 180 minutes and the like in sequence according to the same method.
Experiment 1
The base layer is made of a polyester-ammonia fabric, and the printed pattern is a long hexagon. The change of the long hexagonal printed polyurethane fabric before and after water absorption is shown in figure 3. As can be seen from figure 3, after the long hexagonal printed polyurethane fabric absorbs water, the moisture absorption expansion layer absorbs water to expand. If the base layer is used as a skin-close surface, the base layer is not close to the skin after absorbing sweat, so that the wearing comfort of the garment is improved.
Analysis of the air permeability test results:
TABLE 1 comparison of air Permeability of unprinted polyester-ammonia fabric and long hexagonal printed polyester-ammonia fabric at different water contents
As can be seen from the comparison results in Table 1, in a dry state, compared with the non-printed fabric, the sizing material in the long hexagonal printed polyester-ammonia fabric restrains the hairiness on the surface of the fabric, the length of the air-permeable pipeline of the fabric is reduced, the air-permeable aperture is increased, and the air permeability is improved. For unprinted fabrics, as the humidity increases, water occupies the pores of the fabric and a continuous film of water is easily formed between the fibers, so air permeability is significantly reduced. However, at the beginning stage of humidity increase of the printed fabric, moisture is absorbed and expanded by the polyurethane adhesive, and yarns can be pulled, so that the air permeability of the fabric is improved; as the humidity is further increased, water occupies the pores of the fabric and a continuous water film is easily formed between the fibers, so the air permeability is decreased. But the air permeability of the printed fabric is still obviously improved compared with that of the non-printed fabric with the same water content, so that the printed fabric has more excellent hot and wet comfort.
Experiment 2
The base layer is made of a polyester-ammonia fabric, and the printed pattern is diamond-shaped. The change before and after water absorption of the diamond-shaped printed polyurethane fabric is shown in figure 4. As can be seen from FIG. 4, after the diamond-shaped printed polyurethane fabric absorbs water, the polyurethane adhesive absorbs water and expands. If the base layer is used as the skin-close surface of the garment, the base layer absorbs sweat to prevent sweat dripping, and the wearing safety of the garment is improved.
Analysis of the air permeability test results:
TABLE 2 comparison of air permeability of unprinted polyester-ammonia fabric and diamond-shaped printed polyester-ammonia fabric at different water contents
As can be seen from the comparison results in Table 2, in a dry state, compared with the non-printed fabric, the sizing material in the diamond-shaped printed polyester-ammonia fabric restrains the hairiness on the surface of the fabric, the length of the air-permeable pipeline of the fabric is reduced, the air-permeable aperture is increased, and the air permeability is improved. For unprinted fabrics, as the humidity increases, water occupies the pores of the fabric and a continuous film of water is easily formed between the fibers, so air permeability is significantly reduced. However, at the initial stage of humidity increase of the printed fabric, moisture is absorbed and expanded by the polyurethane adhesive, and yarns can be pulled, so that the air permeability of the fabric is slightly improved; as the humidity is further increased, water occupies the pores of the fabric and a continuous water film is easily formed between the fibers, so the air permeability is decreased. But the air permeability of the printed fabric is still obviously improved compared with that of the non-printed fabric with the same water content, so that the printed fabric has more excellent hot and wet comfort.
Experiment 3
The base layer is made of a polyester-ammonia fabric, and the printed pattern is in a snowflake shape. The change of the snowflake-shaped printed polyurethane fabric before and after water absorption is shown in figure 5. As can be seen from figure 5, after the snowflake-shaped printed polyurethane fabric absorbs water, the polyurethane adhesive absorbs water and expands. If the base layer is used as the skin-close surface of the garment, the base layer is not close to the skin after absorbing sweat, so that the wearing comfort of the garment is improved.
Analysis of the air permeability test results:
TABLE 3 comparison of air Permeability of unprinted polyester-ammonia fabrics and snowflake-shaped printed polyester-ammonia fabrics at different moisture contents
As can be seen from the comparison results in Table 3, the sizing material in the snowflake-shaped printed polyester-ammonia fabric restrains the hairiness on the surface of the fabric, the length of the air-permeable pipeline of the fabric is reduced, the air-permeable aperture is increased, and the air permeability is improved in a dry state compared with the non-printed fabric. For unprinted fabrics, as the humidity increases, water occupies the pores of the fabric and a continuous film of water is easily formed between the fibers, so air permeability is significantly reduced.

But the air permeability of the printed fabric is still obviously improved compared with that of the non-printed fabric with the same water content, so that the printed fabric has more excellent hot and wet comfort.
Experiment 4
The base layer is made of a polyester-ammonia fabric, and the printed patterns are linear hexagons. The change of the linear hexagonal printed polyurethane fabric before and after water absorption is shown in figure 6. As can be seen from FIG. 6, after the linear hexagonal printed polyurethane fabric absorbs water, the polyurethane adhesive absorbs water and expands. If the base layer is used as the skin-close surface of the garment, the base layer is not close to the skin after absorbing sweat, so that the wearing comfort of the garment is improved.
Analysis of the air permeability test results:
TABLE 4 comparison of air Permeability of unprinted polyester-ammonia fabric and linear hexagonal printed polyester-ammonia fabric at different water contents
From the comparison results in table 4, it can be seen that, in the dry state, compared with the non-printed fabric, the sizing material in the linear hexagonal printed polyester-ammonia fabric restrains the hairiness on the surface of the fabric, the length of the air-permeable pipeline of the fabric is reduced, the air-permeable aperture is increased, and the air permeability is improved. For unprinted fabrics, as the humidity increases, water occupies the pores of the fabric and a continuous film of water is easily formed between the fibers, so air permeability is significantly reduced.

But the air permeability of the printed fabric is still obviously improved compared with that of the non-printed fabric with the same water content, so that the printed fabric has more excellent hot and wet comfort.
