A7 Printed 313595 B7 by the Ministry of Economic Affairs, Central Bureau of Commerce and Industry Consumer Cooperation Co., Ltd. V. Description of the invention (1) Field of the invention The present invention is based on a re-wettable and heat-bondable polyolefin synthetic fiber treated with a hydrophilic spinning finishing agent Dimension, its preparation method and non-woven products prepared by weaving. Such fibers are suitable for the preparation of hydrophilic non-continuous materials that can maintain approximately wettability after one or preferably multiple wettings, for example as a topsheet or distribution layer for disposable diapers. The inventor of the invention uses various types of substantially hydrophobic synthetic fibers such as various polyolefin fibers to produce a variety of different materials, but the finished product requires a more or less hydrophilic degree. For example, some hygienic absorbent products, such as the materials in disposable diapers, are examples of this. Some parts of the absorbent product must be transportable and / or retain water such as urine or blood. Changing the hydrophobic surface of polyolefin fibers to be more or less hydrophilic can be carried out in many ways, typically by applying various "Fang silk finishing agents" to the fiber surface during the production process. However, the common problem with such surface-treated fibers is that it is usually quite easy to lose hydrophilicity. For example, polypropylene "hydrophilic valvi", in which the hydrophilicity is provided by Fang silk finishing agent, usually loses its hydrophilicity after a single wetting. Obviously, it is undesirable when the male suspect must maintain a certain degree of hydrophilicity after several wets, such as disposable diapers. It is known in the industry to use polysilicone compounds in spinning finishing agents to maintain the hydrophilicity of the fibers treated by the finishing agent to a certain extent. Therefore, EP 0 4 10 48 5-A1 (corresponding to US 5,045, 387) describes the application of the surfactant composition on the surface of the fiber or fibrillated film to apply the Chinese national standard (CNS) to the paper standard of hydrophobic polyolefin fibers. ) A4 specification (210'〆297mm) C * Please read the notes on the back before filling this page)

Description of the invention (2) A method of providing hydrophilicity to non-hoe materials of dimensional or fibrillated films. The surfactant composition includes water-soluble polyalkylene oxide polymers Dimethicone is combined with antistatic compounds and / or alkoxylated tris sesame glyceride. However, treating polyolefin valvi with polysilicone as described in EP 0 41Q 485-A1 has certain disadvantages. Including 1) the polysilicon on the surface of the fiber causes the strength of the nonwoven material containing the fiber to decrease, 2) the production problem of the fiber production process, the polysiloxane compound is easy to cause fluffy fiber bundles, 3) it is difficult to curl and card the fiber because Polysilicon compounds often lead to low friction of Kanwei / Jinge. 4) Polysilicon compounds are not easily decomposed by biosynthesis. As a result, for example, Jijie Panwei produces equipment that causes waste disposal, and 5) polysilicon compounds are equivalent expensive. Therefore, we hope to use the square silk finishing agent to obtain the hydrophilic surface properties of the hydrophobic polyolefin fiber. The spinning finishing agent first contains a hydrophilic compound, but only slightly soluble in water, so the hydrophilic property is more permanent; second, it contains no or only a very small amount Polysilicone can avoid the aforementioned disadvantages of non-fabric strength reduction caused by polysilicone. Another method to provide permanent hydrophilicity to polyolefin fibers is to mix surfactants into the molten polyolefin before spinning the fibers. This method is described in US 4,578,414 (mixing a wetting agent with a polyolefin of one component) and EP 0 34 0 763-A1 (mixing a surfactant with polyolefin to produce a sheath and S-type bicomponent fiber sheath ingredient). However, these methods compare that the surfactant is only used as a surface treatment method, and has the disadvantage that a relatively large amount of active agent is required. Because the surfactant is quite expensive compared to the fiber polymer (polyolefin such as polypropylene or polyethylene), it is easy to cause a significant increase in production costs. As a result, even though such fibers have good hydrophilicity, their price is quite expensive and their use is limited. Another point of consideration for this method is that it relies on the migration of additives through the polymerized paper method in the Shitong system. The Chinese National Standard (CNS) A4 specification (210X 297mm) is used-5 _ (* Please read the precautions on the back (Fill in this page again)

Description of the invention (3) When the substance reaches the surface of the fiber, the additive is partially removed when wet, and it takes a few hours for the fiber surface to recover to a sufficient additive concentration tank, typically a few hours. At the same time, in other words, before the effective surface concentration of the additive has been reached, the fiber does not have the desired hydrophilicity. These shortcomings of the prior art can be solved by the present invention * The present invention provides a method for producing a rewetable hydrophilic polyolefin thread using a square silk finishing agent that is substantially free of polysiloxane or contains only a very small amount of polysiloxane.

Other aspects of the present invention are based on the embellishment dimension produced according to this method, the hydrophilic non-woven fabric produced from such fibers, and the method of making this non-woven fabric. Development: > Note that according to the word "Polyolefin Shi J" indicates that the fiber of the present invention is produced from polyolefin or its copolymer, including isotactic polypropylene homopolymer * and its ethylene, 1-butene, 4-Methyl-pentene copolymers such as opportunity copolymers, and linear polyethylenes of different density, such as high density polyethylene, low density polyethylene and linear low density polyethylene. Used to produce polyolefin fiber melt The body may also contain various conventional dimensional additives, such as calcium stearate * antioxidants, process stabilizers and pigments, including thickeners and colorants such as TiOs, etc. The payment may be a single-component or two-component valvi, the latter For example, the sheath and core are two-component relays, and the core position is eccentric (partially round center) or concentric (approximately at the center of the circle).

Description of the invention (5), in which the fibers are drawn and drawn in a single workshop. (" Read the precautions on the back before filling in this page.) For Fangsi, the melted fiber components are guided by separate extruders through the distribution system and through the holes of the spinning nozzle. The extruded melt is then guided through the «quenching duct, where it is cooled and solidified by the air flow, and at the same time the long fibers are drawn and gathered into bundles, typically hundreds of fibers. After quenching the catheter, the spinning speed is typically at least about 2 (30 n / fflin, more typically about 400-2500 n / Min. After curing, the long-dimensional dimension is treated with the first spinning finishing agent. The typical process is to use a spur roller. * However, other systems such as spraying long fiber bundles or immersed in Fangsi finishing agent are also suitable. In the Fangfang method, the drawing system uses so-called offline drawing or offline drawing, which is completely separate from the spinning method as described above. The stretching process typically includes a series of hot rollers and a hot air oven in which many long soil dimensional bundles are drawn simultaneously. The long fiber bundles first pass through a set of rollers, then through a hot air oven, and then through a second set of rollers. The typical temperature of both air ovens is about 50-340 Ό, such as about 70-13Qt !, the temperature is selected according to the type of fiber, for example, the typical polypropylene fiber dimension is 115-135 ^, polyethylene fiber is 95-105t :, economic The printing and printing of polypropylene and polyethylene bicomponent fiber of the Ministry of Standards and Staff Consumer Cooperative is 110-12 ϋυ. The second group of hot rollers is faster than the first group, so the heated long ray beam is based on the ratio of the two speeds (Called stretch ratio or draw ratio Stretching. You can also use the second oven and the third group of hot rollers (two-stage stretching). The speed of the third group of rollers is faster than the second group. In this case, the stretching ratio is the last and the first group of rollers. Speed ratio. Similarly, additional sets of rollers and multiple ovens can be used. The fibers of the present invention are typically drawn using the following draw ratios: about 1.05: 1 to about 6: 1, for example, polypropylene fibers from 1.05: 1 to 2 : 1, and polypropylene fiber and polypropylene / polyethylene two-component yarn dimension from 2: 1 8 This paper scale is applicable to China National Standard (CNS) Α4 specification (21〇Χ: 297 mm) Employee consumption of the Central Standards Bureau of the Ministry of Economic Affairs A7 _!

After stretching, the long fiber bundles are treated with a second square green finishing agent, such as using a roll or by sprinkling or dipping. Changwei can be selectively heated before crimping, such as using superheated or saturated steam Heating, or infrared heaters, etc. raise the temperature and melt the ingredients of the wire finishing agent. The melting of the wire finishing agent is better than curling It is carried out before, but can also be carried out in the drying step inside the crimping machine or after aging. The energy required for heating and melting the lubricant can come from the long fiber bundle itself, and the long-wrap dimension bundle has been heated during the stretching process, or it can be As mentioned above, it comes from water vapor or infrared radiation. The friction in the crimping machine (which in turn affects the cohesion of the fiber web produced by the irrigation and maintenance) can be adjusted to a certain degree by adjusting the process parameters, especially the pressure of the stuffing box compartment used for crimping, but only It is feasible in certain scopes * The painting is defined by the spinning finishing agent. The drawn fiber is usually deformed (crimped) to provide a "wavy" Μ to the fiber, which is suitable for carding. The effective deformation Μ and the fiber are quite large For curling, high speed can be obtained in the carding comb, such as continuous carding speed of at least 80 in / Min, typically at least about 100 n / min, in many cases at least 150 n / min or even 200 n / ainM. Crimping is typically done using so-called stuffing boxes. The long fiber bundle is guided into the compartment in the stuffing box by a pair of pressure rollers, where it is not drawn forward in the compartment, causing pressure / turning into curl. The degree of curling can be controlled by the pressure of the roller in front of the stuffing box, the pressure and temperature in the compartment, and the thickness of the long fiber bundle. In addition, the long fibers can be sprayed through the nozzles, and the air can be shaped.

Τ C Please read the precautions on the back before filling this page) Employee Consumer Cooperative Printed A7 _____B7_ V. Description of the invention (7) It is also used for asymmetric bicomponent fiber, which can avoid the curling device. The reason is that the heat treatment fiber releases the fiber tension and causes shrinkage, which results in a three-dimensional space. The fibers of the present invention are typically deformed to the extent of about 5-15 rolls / c®, typically about 7-12 rolls / c® (the number of rolls is the number of dimensional bends). For example, after crimping the fibers in the stuffing box, heat treatment is typically used to fixedly reduce the tension that may exist after the stretching and crimping process, thereby making the deformation more permanent. The fixing and drying of fibers are important factors for the hydrophilicity of the final product. The reason is that the durable hydrophilic effect is partly due to the fact that the hydrophilic component only slowly dissolves in water. These components are easier to dissolve when mixed with a small amount of water, such as residual water from the fiber surface of the production process, so it is important to remove the residual water as much as possible. Of particular importance, the hot air in drying units such as drum dryers *, drying and thermosetting channels is evenly distributed. The reason is that the moisture content in the fiber is low and the distribution is even, which affects the hydrophilicity of the final product Permanent, as stated above. The residual water content is preferably less than 2.0%, and more preferably less than 1.5% by weight based on the weight of the heavyweight. Fixing and drying can be performed at the same time. The typical way is to guide the long fiber bundle from the stuffing box through a hot air oven, for example, through a conveyor belt. The temperature of the oven depends on the composition of the mineral dimension, but it is lower than the fiber polymer or (in the case of two-component secondary dimension) lower than the melting point of the low melting point component. During the fixation process, the valium undergoes the crystallization process. The crystallization process locks the dimensional dimension to the curl shape, which can make the deformation more permanent. Heat treatment can also remove a certain amount of water from the square silk finishing agent. The fiber depends on the type of soil dimension and other factors, and is typically dried at 90-130¾, such as 95-125t: Fanpu temperature.

Description of invention (8) Then, the fixed and dried long fiber bundles are guided to a cutting machine, where the fibers are cut into short fibers of the desired length. Cutting is typically done by passing the fiber through a wheel with a radially arranged knife. The fiber is pressed against the blade by the pressure of the roller and then cut to the required length. It is equal to the distance between the knife and the knife. The fibers of the present invention are typically cut to lengths of about 18-150 M, more typically about 25-1QQ nm, especially about 30-65 μ, depending on the carding equipment and fiber fineness. The length of about 38-40 is suitable for fibers with a fineness of about 2.2 dtex, and the length of 45-50 μ is suitable for 3.3 dtex payment. In summary, the main requirements for spinning finishing agents for square yarns and drawn polymer fibers include the following: 1. Need to contain a certain amount of antistatic agent, M to ensure that the payment is not charged in the square yarn and the drawing or carding process ; Anion, catfish and non-ionic anti-static agent can be used in Fangsi finishing agent, κ and amphoteric compounds and salts can also be used. 2. If there is a lag, the mattress contains a quantitative cohesiveness providing agent to ensure that the long fibers remain bundled, so that their processing will not be entangled; neutral vegetable oils, long fermentation, ethers and esters, creatinine and nonionic surfactants Commonly used for this purpose. 3. 馎 contains adjustable fiber / fiber and fiber / metal friction components during the production process, so the long dimensional dimension will not be worn or broken during the manufacturing process. In the special spinning stage, the fiber / gold friction, the fiber / metal friction drawing roller, and the fiber / fiber and fiber / metal friction of the curler need to be adjusted. 4. It is usually necessary to add emulsifier or surfactant M to maintain the water solubility of each component in the water solution. Fang silk finishing agent is also used to adjust the entanglement dimension / entanglement dimension and fiber / golden friction in the alkaning process, and is usually used in spinning and drawing spinning finishing agent.

Invention description ( 9) Therefore, no further processing is required before the carding. Antistatic agents are all components required for the finishing agent of polyolefin fibers. The typical values of the usual antistatic ingredients under Μ are used as a guide to the relative efficiency of their antistatic properties: no salt 1GQ, yang chizi 80-10 (1, anion 7 5-90, non-chichi 50-70, fixative 30, mineral oil and Silicone 0-10, lubricant 30-50. It is known that cationic antistatic agents are more effective than anions, so appropriate cationic antistatic agents can be used at much lower concentrations. The present invention is based on the second step of spinning green and stretching The square silk finishing agent can meet the requirements of antistatic agent and hydrophilic lubricant content listed above, M and adjust the friction of fiber / fiber and fiber / metal. The further advantage of spinning finishing agent is that it can be used as a processing in the carding process Auxiliary agent, so it provides the entanglement / fiber and fiber / gold friction required to provide sufficient carding. As a result, even with a relatively high carding speed, a carding net with uniform fiber distribution can be obtained. Employee consumption cooperation of the Central Kneading Bureau of the Ministry of Economic Affairs Du Yinzhu (丨 Please read the precautions on the back before filling this page) The pH of the prior art square silk finishing agent (including the amine antibacterial agent or fatty acid amide condensate) is usually slightly acidic, typically below pH 4. Under these circumstances, amine nitrogen is often protonated, so it can be used as a cationic antistatic agent. Perhaps this protonation can also contribute to the stability of the dispersion. However, at higher pH values such as 5-6, The amine group is not protonated, so the amine is not cationic. It is used for applications that do not irritate the skin, such as for the technical use of Felt Panwe. These amines often use low pH. In addition, they can also be used with low pH. To avoid the growth of microorganisms and reduce the appearance of Fang Sao products due to the discoloration and discoloration of the gas. But for the purpose of the present invention, the present invention relates to fibers used in hygienic absorbent products such as disposable diapers, so it must be avoided that the pH is too low This paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -12-A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs V. Description of the invention (10). The pH of the spinning finishing agent used to produce the fiber of the present invention is relatively high to avoid acid-induced skin stimulation. If several acids are needed to stabilize milk fatigue or dispersion *, it is preferred to use acetic acid or other volatile acids. At least part of the volatilization in the drying step of the drawing process, so that the PH of the fiber coating film after the finishing is high enough to avoid acid induced skin full stimulation (acid volatilization * causes the pH to increase from 4 or below of the spinning finishing dispersion to the dry coating film on the fiber About 5-6). Therefore, the anti-jingning agent of the present invention must have a pH (in a 10% aqueous solution) of not less than 4.0. More preferably, the pH is not less than 4.5, such as 4.5-6.5, such as 5.0-δ · β ° The special advantages of the silk finishing agent composition used in the present invention are due to the polyolefin, especially the surface of the polypropylene becomes partially oxidized during the processing by the Changfang technology. Thus, although the polyolefin is known to be hydrophobic, it is certain There may be non-strictly hydrophobic surface properties. As a result of this partial oxidation, several hydroxyl and carboxyl groups M and aldehyde groups and sugar groups are directed to the surface. The oxidation site has an anionic character, which means that in principle, any aqueous solution of anionic components that is intended to be applied to Myanmar is rejected. As a result, the coating film on the surface of the fiber is uneven and less effective. Therefore, the fiber has the disadvantages of being hydrophilic and not durable and deposited on the equipment during the carding process. The cationic silk finishing agent of the present invention (that is, in the aforementioned pH range) provides a positive contribution to the affinity of long fibers to the permanent hydrophilicity of the system. The bond between the long-twisted dimensional and square silk finishing agent's cationic components (see below for the decomposition of the surface of the kapf fiber / long fiber) is not a covalent bond, but it has ionic properties. This is not permanent, especially when the subsequent fiber water or This is especially true when water is in contact.

Description of the invention (11) When the bond * is combined with the low solubility / dispersion of the spinning finish component, the effect is sufficient to meet the hydrophilic "semi-permanent" Demand (that is, rewetting after one or more applications). The hydrophilic lubricant of Fangsi finishing agent can be maintained on the surface of 缳 维. Therefore, since the lubricant has low affinity for water and / or is only slightly soluble in water, the fiber provides “semi-permanent” hydrophilicity. Of particular interest are hydrophilic ingredients, which are only slightly soluble in water due to their size and / or structure. "Lubricant" can be defined as a general term as a friction control agent * that can increase or decrease friction. The friction to be controlled is fiber / valve friction (such as the friction between long fibers of long bundles) or entanglement / metal friction (such as the friction between long fibers and metal parts of fiber production equipment). It can be in static or dynamic conditions. Next measurement. The friction here refers to the friction in the direction of the bodily dimension, and the friction (or friction) in the transverse direction of the fiber is called cohesion. Of course, the two types of friction are affected by the spinning finishing agent. The following characteristics are expected when producing fibers for high-speed carding operations: 1. High cohesion is required in order to obtain reasonable production properties, such as easy handling due to tighter bundles. It also affects the degree of filling in the tank, which in turn can obtain a larger amount of batch material and thus higher productivity. The bulky bunches (due to the low cohesion of the fibers) tend to cause undesirable accumulation of fibers on the rolls and the "sunflower wheel" in the Fangsi section. 2. It is expected that medium (controlled) weave / metal friction, high weave / golden friction will be suitable for some purposes, and low-fiber / golden friction will be suitable for other purposes. The static dimensional / metal friction must be high enough to prevent undesirable slippage during processing. Other aspects * The fiber / golden friction may be high.

The antistatic agent used in the present invention is compliant to obtain sufficient antistatic effect, while generally not Interfere with the semi-permanent hydrophilic properties provided by hydrophilic lubricants. Because effective antistatic agents are often water-soluble, choosing the right anti-calender agent often involves the desired hydrophilic effect of the lubricant on the one hand, and the anti-opening effect expected from the other side. The trade-off between electrical effects. The fourth ammonium compound is usually a good antistatic agent. The ethoxylation of this product can increase its solubility in water, but the antistatic effect caused by the dilution effect is less significant. Water solubility or hygroscopicity Change Substances can promote the antistatic effect, but when the system is wet, the compounds are easily transferred to the liquid phase, thus reducing the permanence of the effect, so the compound must be carefully selected.

The classification can be based on the description in the European Community Official Journal L2 57, 1 983. The viscosity of the spinning finishing dispersion is affected by the size of the dispersed particles or droplets. The particles are small in size and usually have a low viscosity, and a thin and uniform spin finish composition can be obtained on the fiber surface. This in turn provides Burmese with uniform fiber / fiber and fiber / gold friction characteristics, which can be uniformly deformed in the crimping machine, and then produce a uniform carding net during the carding process.

For typical fine fibers with a diameter of, for example, 15-20 μ®, the particle size of the Fangsi finishing dispersion is preferably at most about 5 iU, more preferably at most about 2, and most preferably at most about 1. In principle, the average particle size is usually at least one level smaller than the fiber diameter, but it is determined to a certain extent according to the two materials. The small particle size required to disperse the particles can be achieved in two ways. The first way is to use a considerable amount of emulsification Agent, but it is not Emulsifier, which will lead to the permanent loss of hydrophilicity. The second way to obtain small particle size and is the best way is to use mechanical methods in the preparation of dispersions, such as the use of special homogenization equipment, high shear dispersion equipment or high speed Mixer. Although it is desirable to keep the amount of emulsifier to a minimum, a stable dispersion of very small particles (typical average size less than 2 tfIB) to generate and maintain dispersion or the amount of emulsifier with a stable emulsion containing droplets usually requires a limited amount of M Use. Therefore, the typical amount of emulsifier present is less than 10% by weight, more typically less than 8% reset ratio, such as 4-7% by weight. Ideally the amount of emulsifier needs to be as small as possible or even completely deleted. Suitable emulsifiers for the square silk finishing agent of the present invention are, for example, fatty acid ethoxylates and fatty acid ethoxylates such as general formula I (please read the precautions on the back before filling this page)

According to the present invention, it is expected that the surface obtained by the method may be slightly decomposed during the process of production. The term "decomposition" means that the polymer on the surface of the fiber undergoes a controlled decomposition to obtain anionic surface groups, which can form ionic bonds with the cationic component of Fangsi finishing agent, thus helping to organize Fangsi The agent is maintained on the fiber surface. The decomposition of the surface of the long fiber is carried out when the polymer is sent out of the chess set and exposed to air. When the oxygen in the air reacts with the polymer to a certain extent, the polymer decomposes. Decomposition especially includes chain scission and carbon oxidation at certain positions. As a result, carbon-containing chemical groups such as = C0, -CH0 and -C00H can be measured on the surface of the dimensional metal. These groups have anionic properties, so they are easily used to treat The cationic group in the spinning finishing agent of Victoria is attracted. Various factors K must be considered to select the desired decomposition of the fiber surface. The first factor is that the spinning process must be carried out at a temperature clearly above the melting point of the polymer.

Invention Description (18) Therefore, the spinning temperature is at least 9GI higher than the melting point of the polymer, preferably at least 100 higher, typically at least 110¾ higher. Another factor is the quenching air flow in Fang Sihao. In this way, the quenching air flow rate is high, and the fiber is cooled more quickly. As a result, a low degree of fiber surface decomposition is obtained and a higher degree of decomposition can be obtained when a lower air flow rate is used. Highly decomposable (obtained by low quenching air speed) and a hydrophilic spinning finish with a high affinity for the surface of partially decomposed fibers, which can lead to improved permanent hydrophilicity of Valerian. Similarly, non-fibrous materials produced from fibers Have the same nature. However, the degree of decomposition of the fiber surface must not be high enough, because too high decomposition results in a decrease in the strength of the non-woven fabric, but the hydrophilicity of such fibers and non-woven fabrics has good durability. In principle, the degree of decomposition of the fiber surface is easy to measure in the surface layer, because this decomposition is believed to be a phenomenon that only affects the appearance of the fiber, and the middle of the fiber is believed to be largely unaffected by the decomposition process. However, in practice, there is currently no separate method for determining the degree of fiber surface decomposition. The decomposition of the surface of the aged fiber described below is actually an estimate after analyzing the entire Pan Wei. In this way, the degree of surface decomposition of the mounting dimension can be quantified as the relationship between the MFI (melt flow index) of the spinning valvi and the MFI of the polymer raw material. The MFI is measured according to ISO 1133-81 (E). Polypropylene fiber MFI (| S) i / MFI (rough materials): ratio, for example, in the range of about 2.4-3.0. The production of non-woven fabrics by bonding the carded web containing the valvi of the present invention can be carried out by known means, for example, by rolling or hot air oven for thermal bonding, ultrasonic bonding or infrared heating.

The modified part of the standard method is to perform three breakdown measurements on the exact same point on the non-woven fabric, and replace the lower absorption point (filter paper) after each breakdown round. The non-woven fabrics in each round were not wiped off by drying or K in any way. Perform three series (three rounds for each series) to calculate the average and standard deviation of the measured values for each round. The breakdown time of the three rounds in the test is at most 2D seconds, preferably at most 10 seconds, more preferably at most 5 seconds. 3 X 1 0 hole method Two papers overlap each other with the smooth side facing upwards, and the non-woven sample is placed on top of the center of the paper. Then a 10-hole stainless steel plate (2 2 0 X 50 X 5 ana, hole diameter 15 mm) is placed on top of the non-secondary. A drop of synthetic urine (0.9% NaCl solution) is placed on 10 holes of each non-woven fabric. If the drop is absorbed by the non-woven fabric within 2 seconds, a point will be given. After 60 seconds, place another 10 drops as in the first round. If absorbed within 2 seconds, give another point. After 60 seconds, the third round is performed in the same manner, so the total score is 3D. If the score is greater than 27, the non-woven fabric is called "Semi-permanent Central Bureau of Standards-Ministry of Economic Affairs-Industry and Consumer Cooperatives Printed Liquid Fangmu Test. Another suitable method for determining the hydrophilicity of non-woven fabrics is the absorption of non-woven materials according to ED AN Push the Wan test (No. 10.1-72) to conduct the liquid absorption time test.

The aforementioned liquid absorption test can also be modified with certain small amounts to determine the hydrophilicity of mineral dimension with M. To determine the hydrophilicity of the fiber, the fiber to be tested was carded at 15 Β / Bin to prepare a carded web with a basis weight of about 10 g / m, and then the carded web was used to obtain a sample with a weight of 5 g. The rest of the tests were conducted according to the ED AN A test procedure (10.1-72). When using non-sickle or weave dimensions, the absorption time is defined as the time interval between the moment when the basket containing the non-woven or fiber sample hits the liquid surface and the sample is completely submerged under the liquid surface. In the aforementioned liquid absorption test in water, the wetting time of the non-woven or hydrophilic fiber sample needs to be at most one minute, typically at most 30 seconds, preferably at most 20 seconds, more preferably at most 10 seconds, and most preferably at most 5 seconds. Rewetting test The rewetting of non-woven fabrics is measured according to the EDANA stacking method No. ERT 151.0-93. The result Mg is expressed as the average of three individual measurements. This test measures the barrier capacity of non-woven fabrics as a liquid hip to be transported from near-saturated absorbent materials to dry pad absorbent materials. The absorbent material under the non-contained object is 85 stoneware liquid cells. After scraping for 3 minutes, the paper block is placed on the top of the non-woven fabric, and the weight is placed on the top of the paper extinction. Remove the weight after 2 minutes and record the weight gain of the paper.

The calculated value of the adhesion index of a specific sample is multiplied by 20 divided by the K real basis weight (g / aa), thus compensating for the fact that the non-fabric strength and basis weight change. It is expressed in the bonding temperature range of adhesion The maximum value of the index. The fiber and non-woven fabrics of the example are prepared as follows: Polyolefin raw materials (isotactic polypropylene) use the conventional square wire (long square) technology, using a spinning speed of 2GQQ B / ain square to form a fiber male, and obtain the number of Hundreds of long fiber bundles. After the fiber is quenched with air cooling, it is treated with the squeegee M first silk finishing agent. * Then using a hot roller and hot air oven sister to perform a two-stage drawing operation offline drawing * The temperature is 115-13 5t: The drawing ratio is about 1.25: 1. Then, after the stretching, the long-shock dimension (using the roll) K is treated by the second spinning finishing agent. In these examples, the second spinning finishing agent is the same as the first The spinning finishing agent is the same. Then the long fiber is curled in the stuffing box crimping machine, and then annealed in an oven at a temperature of about 1251C to reduce fiber shrinkage during thermal bonding and make the hydrophilic component of the spinning finishing agent evenly distributed on the fiber surface. Cut the long-duration to the length of the centipede to produce the short-duration. The fineness of the fiber is 22 dtex, the fiber Danny number is 1.8-2.1 cN / dtex, and the elongation at break is 350-420%, about 10-13 Coil / ca, and the cutting length is 41 or 45 am.

Description of invention (22) Tensile strength and elongation are measured in the direction and transverse direction of the frame (as defined above) (that is, using the EDANA push test), and bonded The sex index is calculated based on the tensile strength measurement value as described above. In addition, the properties of breakdown, rewetting and water repellency * were also measured * using the same method as described above. The rationality, that is, the suitability of Siwei for carding, is determined by the use of Jianjun Panwei Net Cohesion Test. The test method is to measure the length of a thin carded web of about 10 that can be supported at a substantially horizontal position without breaking due to its own weight. The length of the carded web is increased at a rate of about 15 b / min. The way of proceeding is to remove the carding net from the horizontal machine at a K 15 a / min speed in the horizontal direction. This speed is the carding speed used in this test. The higher the friction between Panwei and Mine, the higher the combability, and the higher the cohesion length of the Valvi net. The dimensional / fiber friction is related to many factors, such as the composition of the second spinning finishing agent and the degree of deformation M and the permanence of the deformation. The fiber / golden friction is also important for carding; if it is too high or low, the fiber is difficult to pass through the card. Polyolefin fibers that are very suitable for carding are typically supported in the aforementioned Panway mesh cohesion length test, supporting about 1.5 dishes or K, for example 1.5-2.5 m. Fibers designed for high-speed carding preferably support slightly longer, that is, at least about 2.0 a.
