Description
Technical Field
The invention relates to a fabric and a preparation method thereof, in particular to a polyester-nylon interwoven fabric and a preparation method thereof.
Background
The frosted fabric is one of the varieties of bedding articles used in winter, the surface of the fabric is filled with dense fluff through a frosting process, and the warm feeling and the soft feeling are improved when the fabric is contacted with skin. However, the nap on the surface of the yarn continuously falls off after friction and stretching in the use process of the napped yarn, so that diseases on the respiratory tract of people can be induced, and the whole household environment is influenced.
Chinese patent application number CN201611187329.9 discloses a dyeing and finishing method of a brushed fabric, wherein the warp yarn of the fabric is cotton yarn, the weft yarn is sea island yarn, and the weave is warp weave; the process flow comprises the steps of turning cloth and sewing heads, singeing, enzyme rolling and desizing, scouring, bleaching, tentering and whitening, surface milling, printing, steaming, washing, softening and shaping, preshrinking and rolling of finished products, wherein in the milling step, 600-mesh sand skin is adopted, the pressure of all press rolls is 1-2bar, and the rotating speed is 1800-2400r/min. However, the fabric manufactured by the method is easy to break the selvedge during soft shaping and has harder reverse surface due to the fact that the weft yarns are sea-island yarns and high-shrinkage polyester POY in the processing process. In addition, as the difference of the two materials in the warp and weft directions is large, the synthetic fibers on the back face are penetrated to the front face, so that the cloth cover has different hairiness lengths, and the risk of pilling in use is caused.
The Chinese patent application No. CN201210182980.2 discloses a chemical fiber fabric and a preparation method thereof, wherein the fabric is formed by interweaving warps and wefts, the warps are polyester yarns, the wefts are polyester-nylon composite yarns, the interweaving mode is twill weave, and the preparation method comprises the following steps: weaving grey cloth, desizing, degreasing, splitting, reducing, preshaping, sanding, dyeing, tentering, setting, finishing, stacking and checking. However, the fabric prepared by the method has fine fluff on the surface, and because of the adoption of superfine fibers, the fluff in the unit area of the fabric is too much after the fabric is opened, so that the surface viscous friction resistance of the fabric is extremely high, and the fabric has poor hand feeling softness and is easy to dust and stain.
Disclosure of Invention
The invention aims to: in order to solve the technical problems in the prior art, the invention aims to provide a fabric with fine and close velvet feeling, low unhairing rate and excellent fuzzing and pilling resistance, and a preparation method thereof.
The technical scheme is as follows: the polyester-nylon interweaved fabric is formed by interweaving warp yarns and weft yarns, wherein the warp yarns and the weft yarns are one of polyester filaments and nylon filaments, the warp yarns and the weft yarns are filaments of different types, the fineness of the polyester filaments and the nylon filaments is 75-200D, and the number of single fibers is 72-288F.
Further, the interweaving mode of the warp yarns and the weft yarns is plain weave, 1/2 twill or 1/3 twill.
Further, the polyester filaments are cationic polyester filaments.
Further, the warp density of the fabric is 24-90 roots/cm, and the weft density of the fabric is 27-80 roots/cm.
The preparation method of the polyester-nylon interwoven fabric comprises the following steps of: cleaning, milling, dyeing and softening and shaping;
the cleaning procedure comprises a cleaning agent and sodium carbonate;
the method comprises the steps of performing milling, namely padding a fabric with a working solution, and performing milling treatment after the fabric has a liquid carrying rate of 120-140%, wherein the working solution comprises an antistatic agent, glycerol and polyethylene glycol, 10-12 sand skin milling rollers are adopted in the milling treatment, and the number of sand skin is 1200-1600 meshes;
the dyeing process adopts cationic dye for dyeing;
the soft shaping procedure, soft working solution includes: macromolecular lipid softener film ETS and imidazoline quaternary ammonium salt softener film HRX.
Further, in the cleaning solution, the concentration of the cleaning agent is 8-12g/L, the concentration of sodium carbonate is 5-8g/L, the cleaning time is 30-50min, and the cleaning temperature is 40-50 ℃.
Further, the cleaning agent comprises the following components in parts by mass: 25-35 parts of fatty alcohol polyoxyethylene ether MOA-9, 3 8-12 parts of fatty alcohol polyoxyethylene ether MOA-3 8, 8-12 parts of fatty alcohol polyoxyethylene ether peregal O-15, 2-5 parts of dioctyl sodium sulfosuccinate, 1-2 parts of glycerol polyoxypropylene ether and the balance of water, wherein the total weight is 100 parts. In the cleaning step, the oiling agent and the oligomer on the fabric are cleaned by the cleaning agent, so that the risk of color spots and color points easily generated in the subsequent dyeing step can be reduced.
Further, in the working solution, the concentration of the antistatic agent is 0.2-0.6g/L, the concentration of the glycerol is 8-12g/L, the concentration of the polyethylene glycol is 1-3g/L, the antistatic agent is one of octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate and dodecyl dimethyl benzyl ammonium chloride, the polyethylene glycol is one of polyethylene glycol 200, polyethylene glycol 400 and polyethylene glycol 600, and the polyethylene glycol can be adhered on the surface of the fabric to form a film, so that hard damage of milling on filaments can be reduced to a certain extent, and the fabric can obtain a short and dense hairiness fabric.
Under the condition that the milling roller rotates at a high speed, more static electricity and heat can be accumulated on the cellulose fiber fabric or the synthetic fiber fabric, so that the milled hairiness is adhered to the fabric or the milling roller, and seriously even the hairiness is deposited among gaps of abrasive materials, so that the milling effect of the cloth cover is poor, and the hairiness is different in length. Although the addition of antistatic agents reduces the build-up of static electricity to some extent, the effect is not obvious and heat cannot be dissipated.
If padding is performed on the working solution containing only the antistatic agent, free water attached to the fabric is distributed among fabric tissues mainly due to fine wool, and under the condition of high-speed running, the water is unevenly distributed under the action of external force, and even partial dehydration is caused. After polyethylene glycol and glycerol are added, the free water on the fabric is uniformly distributed through the synergistic effect of the polyethylene glycol and the glycerol, and the phenomenon of dripping is avoided, so that the fabric surface has better velvet feeling and strength when the fabric is ground.
Further, in the milling treatment, the 1 st, 2 nd and 5 th sand skin milling rollers are reversely rotated, namely the tangential direction of rotation of the sand skin milling rollers is opposite to the running direction of the fabric, the rest is positively rotated, the 1 st sand skin milling roller brushes out weft yarns in the fabric, the 2 nd sand skin milling roller carries out preliminary grinding on the weft yarns to form long hairiness on the surface of the fabric, the 3 rd and 4 th sand skin milling rollers mill the long hairiness into fine hairiness, and the 5 th sand skin milling Mao Gunmo long hairiness is prepared for preventing the long hairiness from being intertwined to cause the milling of the fabric, and a plurality of sand skin milling rollers positively rotate at the back to further mill the long hairiness generated at the front to be finely milled, so that fine and short hairiness is generated on the surface of the fabric.
Further, the pressure of the sanded leather milling roller is 0.5-0.8bar, the rotating speed is 1600-1800 rpm, and the vehicle speed is 40-50m/min.
Further, in the softening process, the softening working solution comprises 20-40g/L of polymer lipid softener film ETS and 30-50g/L of imidazoline quaternary ammonium salt softener film HRX, the shaping temperature is 120-140 ℃, and the vehicle speed is 50-60m/min. The lipid softener is combined with the imidazoline softener to act on amino, amido, sulfonic acid groups and other groups on the cationic polyester-nylon fabric so as to increase the adsorption quantity of the softener on the polyester-nylon fabric, thereby improving the soft and fine hand feeling of the fabric.
Further, the warp retraction of the fabric after the soft shaping process treatment is 10-13%, and the weft retraction is 4-6%. During shaping, positive overfeeding or negative overfeeding is adopted to realize warp retraction, and when the lower deviation (10%) is lower, positive overfeeding is adopted to retract the fabric to be within the range of 10-13%; when the deviation is higher than the upper deviation (13%), the retracted fabric is pulled out to the range of 10-13% by adopting negative overfeeding. The fabric is made into the same time, the strength and gram weight of the fabric are effectively controlled, and the fabric has soft hand feeling. In weft retraction, due to different tension when the grey cloth is woven, a certain error exists in the grey cloth width of 106 inches when the grey cloth is woven, and the width shrinkage is inconsistent in the printing and dyeing process, mainly the width size is controlled during soft setting, and finally the finished product width is 98.2-99.2 inches.
The principle of the invention: according to the polyester-nylon interwoven fabric, the surface area of the fabric can be increased by the filaments with high F number, and the capillary action is further increased. The polyester fiber has extremely low hygroscopicity, the nylon fiber has certain hygroscopicity, but the moisture absorption performance is also very limited, and the liquid carrying of the fabric mainly depends on capillary action among fabric tissues. However, free water is obtained through capillary action of the fabric, and due to the influence of factors such as the action of a sanding roller moving in the same direction or in the opposite direction at a high speed, the dead weight of the water, the movement of the fabric, and the like, the phenomenon of dripping water or uneven water distribution easily occurs on the fabric, so that the cloth cover hair feel of the sanded fabric is influenced, the hairiness length of the fabric is inconsistent, and the hair feel density distribution is uneven. When the fabric is low in liquid carrying rate, the fabric is only padded with clear water in the processing process, and the phenomenon of dripping or uneven water distribution is avoided, but weak hairiness on the surface of the fabric is easily caused during sanding, the hairiness on the surface of the fabric is different in length, and the texture of the bottom plate of the fabric is strong. Further, in order to obtain fine and short hairs and pass the strength of the fabric, the invention adopts the high-mesh fine sand particle abrasive, however, the adoption of the high-mesh abrasive has obvious influence on the hairiness length and the fluff density of the surface of the fabric, and the fine and short hairs cannot be obtained by the fabric. For this purpose, fine hairiness is obtained by matching the rotation direction of the milling roller with the antistatic agent. When the coarser abrasive is adopted for sanding, the weft strength of the fabric is extremely severely damaged, and the damage degree is unexpected because the strength of filaments of the terylene or the nylon fiber is extremely high, but the strength of the fabric is extremely low after rough sanding. This may be related to the fabric itself structure, the weave structure of the fabric of the present invention being plain weave or 1/2 twill or 1/3 twill, i.e. at least 50% of the weft yarns on the surface of the fabric are exposed on the surface. Since the weft yarn direction is perpendicular to the running direction of the roughening roller, the weft yarn is greatly damaged from the action strength or the contact probability.
The beneficial effects are that: compared with the prior art, the invention has the following remarkable advantages: according to the invention, the cationic polyester filaments and nylon filaments with specific fineness and F number are designed for interweaving, and plain weave or 1/2 twill or 1/3 twill is used as a weave structure of the fabric; meanwhile, the printing and dyeing processing technology of the fabric is designed, and through the working procedures of cleaning, milling, dyeing and softening and shaping, the fluff on the surface of the fabric is uniformly and compactly distributed, the fluff length uniformity is good, and the skin-friendly feeling is not stimulated. When the circular track D method and the Martindale method are adopted for testing the fabric, the fuzzing and pilling grades of the fabric are high, so that the use experience of consumers is ensured. Although the fabric is subjected to milling treatment, the chassis of the fabric has better dehairing performance and better dehairing rate, so that a good sleeping environment in bedrooms is provided for consumers, and respiratory diseases caused by hairiness are reduced.

The fabrics prepared in examples 1-5 were tested for performance and the results are shown in Table 1.
Table 1 various internal indexes of the fabrics produced in examples 1 to 5
From table 1, it can be seen that the invention provides a polyester-nylon interwoven fabric and a preparation method thereof, which do not use polyester-nylon composite filaments or other sea-island filaments as raw materials, and do not perform fiber opening treatment on the fabric in the dyeing and finishing process. Fine velvet feeling can be obtained by grinding the surface of the fabric. The fabric has good style, fine velvet feeling, no static inductance, no frosty feeling and no viscous resistance; the fabric has better internal indexes, better strength and better anti-pilling and non-hair falling performance.
The fabrics prepared in comparative examples 1 to 11 were subjected to performance test, and the results are shown in Table 2.
Table 2 various internal indexes of the fabrics produced in example 2 and comparative examples 1 to 11
In comparative example 1, when both the warp and weft directions of the fabric are made of the cationic polyester filaments, the fabric has obvious static inductance, and although the antistatic agent is used in the roughening process, the antistatic agent is already resolved from the fabric after the treatment of each procedure, and the static electricity caused by the material itself cannot be eliminated.
In comparative example 2, when the weft yarn is changed into polyester-nylon composite yarn, the fabric mainly acts on the weft yarn due to sanding, and fine velvet feel on the surface of the fabric is mainly provided by the weft yarn. When the polyester-nylon composite yarn is treated, tiny single fibers form superfine fluff on the surface of the fabric, so that the friction force on the surface of the fabric is extremely large, and the phenomena of serious frosting and high viscous resistance occur.
In comparative example 3, when sodium carbonate was changed to sodium hydroxide in the washing process, the amount was 1-2g/L, the treatment temperature was 90℃and the remaining processes were unchanged. The fabric receives etching of sodium hydroxide as a strong alkaline agent at high temperature, particularly when the single fineness is thin and the F number is high, the etching phenomenon is more obvious, finally, the fabric strength is disqualified, the wool falling phenomenon is serious, and the thickness of the fabric is also thinned.
In comparative example 4, when the cleaning agent was changed to a commercially available degreasing agent in the cleaning process, the color difference was remarkable. The oiling agent and the oligomer on the filaments are not completely removed, so that the fabric is stained back in the dyeing process, and obvious color difference and color spots are formed.
In comparative example 5, no antistatic agent was added to the clear water in the napping process, the napping was messy and the fabric dehairing rate was also higher. Although the fabric is padded with clean water to treat the fabric, the chemical fiber filament fabric is easy to generate static accumulation due to the fiber material, and especially under the condition of high-speed continuous friction, the phenomenon of the chemical fiber filament fabric is more obvious. When the fabric goes through the milling process, milled short piles are instantly adsorbed on the fabric, and the short piles cannot be removed through air suction or mechanical beating. Even in the subsequent process, most of the adsorbed flock remains in the fabric, and the flock removal rate is high finally.
In comparative example 6, 240-400 mesh sand skin is adopted in the sanding process, and the strength and the wool removal rate of the fabric are still large. Because chemical fiber filaments, especially high F number filaments, are very easily hooked and ground apart when ground by a sand skin having coarser particles than staple yarn. The only tie that serves as a bond is the network points on the filaments, since the filaments in the filaments have no cohesive interaction between the radial directions, but these network points are much smaller relative to the cohesive forces between the fibers in the yarn. Whereby filaments are more prone to lint and brute force damage when subjected to external forces.
In comparative example 7, the softening process changed the setting temperature to 150-170 ℃, the rest process was unchanged, and the hand feeling of the fabric was stiff. The setting temperature of the fabric is raised, and filaments in the fabric can reach a designated temperature in preference to the fabric per se at the end of short velvet, and a molten drop phenomenon is formed at the end of fiber, particularly when the fabric is subjected to velvet milling. When the number of filaments in the filament is larger and the fineness is smaller, the filaments can easily reach the softening point, and under the action of external force, the filaments can be reoriented and crystallized to increase the bending stiffness of the filaments, so that the hand feeling of the fabric is hard.
In comparative example 8, the wide bedding fabric is not retracted in the warp direction, namely 0% in the warp direction, the fabric is hard and thin in hand feeling, and the fabric strength is also reduced. The filament fabric is subjected to high temperature and tension in the processing process, and new orientation is easy to generate in a new position. After the filament fabric is shaped by external action, the filament fabric is subjected to reorientation crystallization to increase the bending stiffness of the monofilaments, so that the hand feeling of the fabric is harder, and the strength of the fabric is reduced.
In comparative example 9, polyethylene glycol is not added to the working solution, and when the fabric is subjected to napping, the moisture on the fabric is unevenly distributed, so that the length of nap on the fabric is different during napping, the uniformity is poor, and the anti-napping and pilling performance of the fabric is obviously reduced. This is probably because, when glycerol is added only to the working liquid without polyethylene glycol, the fabric still has a dripping phenomenon or a phenomenon of uneven water distribution on the fabric during sanding. Because the molecular volume of the glycerol is smaller and the acting force with the fabric is weaker, the glycerol and water molecules can quickly permeate between the single fiber tissues of the fabric, and the free movement of the water on the fabric can be reduced to a certain extent. However, this state is unstable because glycerol has a small molecular weight, weak force with the fabric, and weak water and ability. When the fabric is brushed, due to the action of the high-speed brushing roller on the fabric and the action of the fabric, glycerol which is already attached to the fabric is migrated among tissues and fibers on the fabric again due to the action of external force, so that the glycerol is unevenly distributed on the fabric and even is dripping. In addition, as the gram weight of the fabric is lower, the fabric is thinner, the capillary effect is weaker, and the phenomenon can be further amplified. Therefore, when polyethylene glycol is synchronously added to the working fluid on this basis, this phenomenon can be avoided by the synergistic interaction of polyethylene glycol and glycerol.
In comparative example 10, when polyethylene glycol (e.g., polyethylene glycol 800) having a relatively high average molecular weight was added to the working solution, it was found that the roughening effect was rather poor, the hairiness of the cloth surface was not uniform, and some parts even had no hairiness. The reason for this phenomenon is that firstly, when the fabric is roughened, along with the continuous rotation of the sand paper, the roughened fluff is adsorbed on the surface of the roughening roller due to the viscosity of polyethylene glycol, so that the roughening effect of the roughening roller on the fabric is reduced; secondly, polyethylene glycol with high molecular weight is deposited on the surface of the sand skin paper, gaps among surface particles are filled up, the rough feeling of the surface particles of the sand skin paper is reduced, and the surface particles of the sand skin paper with high mesh number are finer, gaps are smaller and are easier to fill up, so that the fabric cannot be ground, and the phenomenon that the surface hairiness of the fabric is different in length or has no hairiness is caused; thirdly, the polyethylene glycol with high molecular weight reduces the friction coefficient of the surface of the fabric and the surface of the roughening roller, the rolling friction between the fabric and the roughening roller is changed into sliding friction, and the roughening effect of the roughening roller on the fabric during the fabric roughening is obviously weakened. In contrast, when polyethylene glycol (polyethylene glycol 100) having a low average molecular weight is selected, the roughening effect is poor and the hairiness of the cloth surface is disordered and uneven. The reason is that when polyethylene glycol with low average molecular weight is adopted, under the action of external force, high-band liquid moisture on the fabric migrates to form a dripping phenomenon during sanding, so that the sanding roller and the fabric have uneven grinding effect.
In comparative example 11, when the F number of the filaments used was less than 72F, the fineness of the single fibers in the filaments was coarse, the cloth cover lacked a feeling of pile, the pile was disordered, and the feeling of touch was hard. When the comparison area of the fabric is reduced, the moisture on the fabric is unevenly distributed, so that the length of fluff on the fabric is different during sanding, the uniformity is poor, and the fuzzing and pilling resistance of the fabric is obviously reduced.
