Example 1

Referring to fig. 1, the embodiment provides a bionic breathable fabric, which comprises a composite surface layer 10 and an inner layer 20, wherein the composite surface layer 10 comprises a bionic surface layer 101, a waterproof breathable film 102 and a fly yarn bottom layer 103 which are sequentially laminated from outside to inside, the bionic surface layer 101 is formed by weaving a four-sided elastic structure 1011, the inner layer 20 is formed by weaving antibacterial yarns, the inner layer 20 is arranged on the fly yarn bottom layer 103, fabric pores of the inner layer 20 are larger than fabric meshes of the fly yarn bottom layer 103, and fabric pores of the bionic surface layer 101 are larger than fabric meshes of the fly yarn bottom layer 103.

Specifically, the antibacterial yarn can be milk silk yarn, and the important raw material of the milk silk yarn or fiber is milk protein, so that the antibacterial yarn contains seventeen kinds of amino acids rich in nutrition, has a natural and durable antibacterial function, and has the effect of moistening skin to human bodies due to the effect of active proteins in the fiber on home textile products with a broad-spectrum antibacterial rate of more than 80% on staphylococcus aureus, candida albicans, fungi and mould. The home textile fabric which is blended and interweaved by the milk protein fibers and other fibers has the advantages of fine and light texture, ventilation, smoothness, elegant and luxury luster and gorgeous color.

The milk made of the milk protein fiber velvet as the filler is warm, soft, good in heat preservation performance and rich in elasticity, has the functions of promoting sleep, preventing mites and resisting bacteria, is beneficial to health, and is particularly suitable for people with allergic physique. Therefore, the bionic breathable fabric has good skin-friendly antibacterial performance.

Further, the composite surface layer 10 is provided with a three-layer structure, and the waterproof breathable film 102 is a novel polymer waterproof material. The waterproof breathable film 102 mainly comprises three layers, namely PP spunbonded non-woven fabric, PE high polymer breathable film and PP spunbonded non-woven fabric. The spun-bonded non-woven fabric has the main functions of enhancing tension and hydrostatic pressure and protecting the middle layer (breathable film), and the real breathable is mainly based on the middle layer PE high polymer breathable film. In the state of water vapor, the water particles are very tiny, and can smoothly permeate the capillary tube to the other side according to the principle of capillary motion, so that the vapor permeation phenomenon occurs. After the water vapor is condensed into water drops, the particles become larger, and the water molecules cannot be smoothly separated from the water drops to permeate to the other side due to the action of the surface tension of the water drops (mutual 'pulling and counterbalance' among the water molecules), namely, the water permeation is prevented, so that the vapor permeable membrane has a waterproof function.

Therefore, when the waterproof breathable film 102 is bonded between the bionic surface layer 101 and the float yarn bottom layer 103, the composite surface layer 10 has good waterproof and breathable properties. Meanwhile, the structural bottom layer of the floating yarn can cover the waterproof breathable film 102, so that the structural strength of the composite surface layer 10 is improved, but the weight of the composite surface layer 10 cannot be excessively increased, and the floating yarn is a good backing material due to the light and thin characteristic.

Further, the bottom layer 103 of fly yarn is woven from polyester fiber material, also known as poly cool fiber and poly acetate fiber, commonly known as "polyester fiber". The polyester fiber has the advantages of good crease resistance and shape retention, high strength and elastic recovery capability, and the knitted fabric is firm and durable, crease-resistant, non-ironing and non-sticky. Can be well bonded or sewed with the inner layer 20, and improves the practicability of the bionic breathable fabric.

Specifically, in this embodiment, a plurality of bonding points are disposed in a matrix between the waterproof breathable film 102 and the bionic surface layer 101 and between the waterproof breathable film 102 and the fly yarn bottom layer 103, and the design of the bonding points through the matrix can ensure the adhesion viscosity, and meanwhile, the air permeability of the waterproof breathable film 102 is not affected, so that the practicability is improved.

In this embodiment, the scale-like texture or feather-like texture is provided on the stamp on the bionic surface layer 101, or the simulated skin texture, that is, the skin color and texture of the animal, is provided on the stamp on the bionic surface layer 101. Different biological or plant textures are formed on the bionic breathable fabric through printing of different biological textures, so that the appearance bionic aesthetic feeling of the fabric is improved.

As shown in FIG. 2, the four-sided elastic structure 1011 of this embodiment is a minimum pattern type woven unit, the 1 st weft yarn of the four-sided elastic structure 1011 is interwoven with the 1 st warp yarn, the 3 rd warp yarn, the 5 th warp yarn and the 7 th warp yarn to form a weave point, the 2 nd weft yarn of the four-sided elastic structure 1011 is interwoven with the 2 nd warp yarn, the 4 th warp yarn, the 6 th warp yarn and the 8 th warp yarn to form a weave point, the 3 rd weft yarn of the four-sided elastic structure 1011 is interwoven with the 1 st warp yarn, the 3 rd warp yarn and the 7 th warp yarn to form a weave point, the 4 th weft yarn of the four-sided elastic structure 1011 is interwoven with the 2 nd warp yarn, the 4 th warp yarn, the 6 th warp yarn and the 8 th warp yarn to form a weave point, the 4 th weft yarn of the four-sided elastic structure 1011 is interwoven with the 1 st warp yarn, the 4 th warp yarn and the 6 th warp yarn to form a weave point, the 4 th weft yarn of the four-sided elastic structure 1011 is interwoven with the 1 st warp yarn and the 8 th warp yarn to form a weave point, the 4 th weft yarn of the four-sided elastic structure 1011 is interwoven with the 1 st warp yarn, the 4 th warp yarn and the 4 th warp yarn to form a weave point, and the fourth warp yarn of the fourth warp yarn is interwoven with the fourth warp yarn and 8.

Specifically, the tetrahedral structure 1011 is a minimum pattern structure of 8 by 8, the tetrahedral structure 1011 comprising an outer surrounding structure, i.e. the surrounding structures formed by the 1 st, 2 nd and 8 th warp yarns and the 1 st, 2 nd and 8 th warp yarns. The enclosed interior is in an x shape, so that the ventilation effect of the middle part can be achieved, that is, ventilation holes are formed, and the composite surface layer 10 is guaranteed to have good ventilation.

Further, the weft yarns and the warp yarns of the four-side elastic structure 1011 in the embodiment are core spun yarns of 30D nylon and 20D spandex, which exert the advantages of the nylon filaments such as stiffness, folding resistance, easy washing and quick drying, and can exert the elasticity of the outer ammonia-coated fiber. Therefore, the bionic surface layer 101 has the quick drying effect, and has good waterproof and breathable properties in combination with the performance of the waterproof breathable film 102.

In the embodiment, the fabric density of the bionic surface layer 101 is 228-117 g/m to 245-132 g/m. The density of a fabric refers to the warp and weft density of the fabric, i.e., the number of warp and weft yarns contained in a 1 square inch fabric. Preferably, the density may be 233 x 124g/m, the grammage may be 85g, and the width may be 130 cm. Through the arrangement of relatively higher density, the structural strength of the fabric can be ensured, and meanwhile, the printed bionic texture can be well reflected.

The bionic lines on the coat 1 can show the beauty of the coat 1, meanwhile, the design of good ventilation and waterproof functions is realized, different performances of the coat 1 are improved (namely, the coat 1 has multiple functions), the coat is good in wearing comfort, meanwhile, the inner layer of the coat 1 is made of milk silk, so that the coat 1 has good antibacterial and skin-friendly performances, and the functionality of the coat is greatly improved.

Example III

As shown in fig. 4, the embodiment provides a manufacturing process of a bionic breathable fabric, which comprises the following steps:

S101, manufacturing the bionic breathable fabric as described in the first embodiment.

Specifically, the manufactured bionic breathable fabric needs to be inspected, and the inspection content is to carry out width, warp and weft yarn density and strength, appearance flaws, greasy dirt or damage and the like on the bionic breathable fabric so as to prepare the quality of the bionic breathable fabric to be qualified, and then enter a subsequent dyeing and finishing process to be dyed and finished so as to avoid waste.

S102, removing sizing agent and impurities from the bionic breathable fabric, and then carrying out singeing pretreatment.

Specifically, after the yarn is spun, loose limiting ends are exposed on the surface of the yarn, so that fluff with different lengths is formed. Therefore, through singeing treatment, fluff on the surface of the fabric is removed, so that the surface of the fabric is smooth and clean.

S103, presetting the pretreated bionic breathable fabric.

The pre-shaping is also called heat shaping, i.e. the desired morphology of the fabric is obtained by heat shaping treatment and its stability is maintained. Specifically, the thermoplastic of the fiber is utilized, the fabric is heated to the required temperature (140-150 ℃) under certain tension (overfeeding of 10%), and kept heated for a period of time (3-5 min), and then cooled rapidly, so that the dimensional form of the fabric is stabilized, namely, the fabric is named as pre-shaping or heat shaping.

The heat-set fabric has the advantages of eliminating internal stress of the fabric, improving dimensional stability of the fabric, eliminating wrinkles on the fabric, improving strength, hand feeling and surface smoothness of the fabric, and improving dyeing performance and fuzzing and pilling of plants.

S104, dyeing the pre-shaped bionic breathable fabric. The dyeing auxiliary agent formula adopted in the dyeing process is that 1-2 g/L of ammonium sulfate, 2-3 g/L of acid leveling agent, 0.5-1.5 g/L of chelating dispersant, 0.01-0.04% of weak acid bright yellow and 0.1-0.3% of acid turquoise blue are mixed according to a bath ratio of 1:20, and dyeing is carried out for 40 minutes at 110 ℃.

Specifically, the fabric is required to be dyed to obtain a required color. The weak acid dye is used for dyeing, namely nylon fiber contains a certain amount of amino and carboxyl, and when glacial acetic acid is added, the amino is combined with hydrogen ions, so that the fiber is positively charged, and dye anions are attracted for dyeing. Meanwhile, the fibers and the dye have the Van der Waals force and hydrogen bond effect, and when the dye bath is weak in acidity, the Van der Waals force and the hydrogen bond play a main role. Thus, an acid dyeing effect is formed.

S105, washing the dyed bionic breathable fabric with cold water, and performing fixation treatment. The auxiliary agent formula of the color fixing process comprises 2% -3% of acid color fixing agent and 1.5g/L glacial acetic acid, and the pH value of the solid dye solution is adjusted to 4.0-5.0 according to the bath ratio of 1:25.

In the above, the amino groups are combined with hydrogen ions after glacial acetic acid is added, so that the fibers are positively charged, and the process of attracting dye anions to dye is the process of fixation. The pH value of the solid dye solution can be adjusted to be 4.0-5.0 by matching with an acid color fixing agent, so that the color fixing process is stable.

S106, washing the color-fixed bionic breathable fabric, taking out, and performing shaping and drying treatment at 130-145 ℃.

After the color-fixed bionic breathable fabric is washed, the drying operation needs to be completed within 12 hours, so that the bionic breathable fabric is quickly dried, and the follow-up steps can be conveniently performed.

The washing process of the bionic breathable fabric after fixation comprises the steps of feeding water in a bath ratio of 1:10 for 1g/L, washing for 30 minutes at normal temperature, draining water, feeding water in a bath ratio of 1:10 for 2.0-4.0% of dispersed color fixing agent, washing for 30 minutes at 50 ℃, draining water, and feeding water in a bath ratio of 1:10 for 1.0-2.3 g/L of soaping powder, washing for 30 minutes at normal temperature.

And S107, pressing the dried bionic breathable fabric by a mold with bionic textures to obtain the bionic breathable fabric with the bionic textures.

Specifically, the printing and pressing manufacturing is carried out through the corresponding bionic texture mold, so that the bionic texture of the required bionic breathable fabric is generated, and the attractiveness of the surface of the fabric is improved. In the embodiment, the pre-shrinking treatment process is carried out on the bionic breathable fabric after fixation, wherein the pre-shrinking liquid is prepared from 2-3 g/L of degreasing agent, 0.5-1.5 g/L of chelating dispersant and 3-4 g/L of sodium carbonate, and the temperature is kept for 30 minutes at 100 ℃ in a bath ratio of 1:8, so that the shaping effect of the bionic breathable fabric can be improved.

The following samples were prepared separately with reference to the foregoing method:

component and production family

The color fastness to washing is tested according to GB/T12490-2007 for samples 1-4, and the measured color fastness to washing reaches more than 4 levels, so that the fabric obtains good color fastness to washing after the color fixing process is adopted.

Compared with sample 4, sample 1-3 has obviously reduced first water washing shrinkage, very small second water washing shrinkage and capacity of maintaining the clothing shape well.

Comparative example

A dyeing and finishing process of elastic soft nylon fabric is described in a patent application document, wherein the application number is 202010298817.7, and the soaping and fixation process is that the soaping time of the dyed fabric is respectively 15, 16, 17, 19 or 15min, wherein the soaping liquid contains 10, 12, 15, 18 or 20g/L of foamless soaping agent D & Pclear produced by Oriental Meijie molecular materials technology Co., ltd, the fixation time is 20, 25, 30, 36 or 40min, and the color fixing agent is placed in a fixation liquid and contains 30, 34, 40, 46 or 50g/L of YD-1012 chlorine-resistant fixation agent produced by eagle textile auxiliary Co., ltd.

Soaping and color fixing treatment process

According to the comparative example, the amounts of the fog gun soaping agent and the YD-1012 chlorine-resistant color fixing agent are relatively large, the color fixing time is relatively long, and the washing-resistant color fastness of grade 5 (comparative example 5) can be realized only after that, but the treatment cost is relatively high.

The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
