Description

Description of the invention (Invention 镅) The present invention is generally directed to a nonwoven composite material. In particular, the present invention relates to a strong, absorbent and soft wiping product. Inventive back-up absorbent product packages such as industrial wipes, food and beverage Service wipes and other similar items that combine several important functions. For example, this product should have good bulk, a soft touch, and should be highly absorbent. This product should be even when wet Good toughness and resistance to tearing. In addition, wipe products should have good tensile properties, and should be resistant to abrasion, and should not deteriorate or degrade in the environment in which they are used. There have been many attempts in the past. Want to enhance or increase the specific physical properties of a wiping product, especially if the wiping product contains a large amount of pulp or paper. Unfortunately, often when steps are taken to increase one of the characteristics of a wiping product, Other characteristics of the product have a negative effect. For example, in pulp products based on pulp fibers, softness and swelling can be reduced or reduced Increased fiber-to-fiber bonding in woven fabrics. Suppresses or reduces fiber bonding by chemical and / or mechanical breakage, but unfortunately negatively impacts product strength. Designed with pulp The challenge for substrate-based wiping products is to increase softness, bulk, and woven texture without reducing strength and / or abrasion resistance.

Mmr · 7999 4 V. Description of the invention (2) In the patent filed by the applicant, the process disclosed is used to produce a soft, absorbent, single-layer fibrous woven fabric with a laminate-like structure. The fibrous woven fabric disclosed in the patent filed by Gentile φ, is mainly formed by the watery slurry of lignocellulosic fibers while reducing the intergranularity of fibers. An adhesive material, such as a rubber elastomer composite, is applied to the first surface of the woven fabric in spaced-apart patterns. The deadweight material provides strong weave to woven fabric and provides the required abrasion resistance on the surface. The dry material can then be applied to the other side of the fabric in a similar way to further provide additional strength and abrasion resistance. — And withered material is applied to the second side of the woven fabric, the woven fabric can be carried into contact with a surface. In particular, the woven fabric is attached to the surface of the crease according to the application pattern of the dead material. The woven fabric is then creped from the creped surface with a spatula. The continuation of the woven fabric mechanically breaks or breaks the fibers existing in the woven fabric, and further increases the softness, absorbency, and bulkiness of the woven fabric. In another embodiment disclosed in the patent application filed by Gentile et al., After applying the bonding material, both sides of the paper woven fabric are creped. Although this technology has been applied to paper products, it has not yet attempted to print composites made of continuous filament fibers with a fibrous composition and a material that can be reinforced and reinforced by the Intellectual Property Office of the Ministry of Economic Affairs. In the embodiment of the patent of Gentile et al.-The disadvantage is that the bonding material usually solidifies or dries under high temperature conditions that can break down continuous long fibers. The composite material ′ 丨 g is intended to have a desired degree of strength in combination with the woven fabric layer of long fibers in the texture of pulp handles, but generally exhibits a poor fibrous composition and binding force. In other words, fibrous materials and / or A7 B7 5. Invention Description (3) Any fiber-rich surface will be more fragile than the continuous filament fiber composition. This can cause undesired abrasion of fiber debris, poor abrasion resistance, and produce materials with lower overall strength. Trying to soften and / or increase the bulk of the composite material will break the binding and binding force of these fibrous materials. Therefore, there is still a demand for pulp-based wiping products. These products include A continuous long-fiber base fabric. Another need is for pulp-based products that are blended with continuous long-fiber base fabrics and that improve the softness of all conventional products, while still retaining strong tenacity. Another requirement is that when the product is wet, the pulp and cypress substrate mixed with continuous long fibers will not be compressed, and at the same time, it can have the three-dimensional aesthetics of textile cloth. The invention of the invention shows that the present invention can provide a non-woven complex that forms a softened ghost entanglement. 5 materials, and above The various drawbacks mentioned are also addressed by the present invention. The method of the present invention includes the steps of providing a hydraulic tangled woven fabric containing a fibrous component and a substantially continuous long-fiber nonwoven layer; applying a bonding material on at least one side of the woven fabric; and lifting the hydraulic pressure Tangled woven fabric on at least one side.

Description of Invention (7) The term "nonwoven fabric" means a kind of woven fabric. The needle is a structure of individual fibers or threads that are interwoven and arranged, but it is not the same as the fabric. Nonwoven fabrics or woven fabrics have been made by many Made by process: 'For example, such as meltblown processes, spunbond processes, and bonded carding,', weaving processes. The basis weight of nonwoven fabrics is usually in ounces of material per square yard (osy) or It is expressed by how many grams per square meter (g is called, and the diameter of the fiber that uses the price tag is usually expressed in microns (note that to convert osy units to gsm units, just multiply sy by 33.91) 〇 Ministry of Economic Affairs The term “microfiber” used in this article printed by the Intellectual Property Bureau's Consumer Cooperative refers to fibers with a small diameter, the average diameter of which is not greater than about 75 microns, for example, having a diameter of about 0.5 to 50 microns Average diameter, or more specifically, microfibers There may be an average diameter from about 2 microns to 40 microns. Another more commonly used to represent fiber diameter is denier, which is defined as all its gram weight per 9,000 meters of fiber.

The term "softening point" as used herein refers to the temperature at which a typical thermoplastic polymer approaches melting change. This softening point usually occurs at a temperature close to or just below the melting change, which is equivalent to a major phase change and / or a change in the polymer structure, which is sufficient to allow relatively strong fusion or to bond the polymer to other materials, such as , Cellulose fibers and / or particulate matter. Generally, at temperatures below the softening point, the molecular arrangement within the polymer tends to be more fixed. In such cases, many polymers are difficult to soften, so they flow slowly and / or otherwise distort to integrate or merge, and eventually fuse or bond with other materials. At about the softening point, the polymer's hydrodynamic force is strengthened so that it can bond firmly with other materials. In general, the softening point of ordinary thermoplastic compounds can be regarded as close to or approximately at the Vicat softening temperature, which is a temperature base that is substantially determined in accordance with ASTM D 1525_91. This means that " this softening point is usually below the approximate melting change of the polymer " and is generally close to or much greater than the Vicat softening temperature of the polymer. As used herein, the term "low softening point composition" refers to one or more items that can be composed of a total of filament filaments (such as an outer sheath, core, and / or side-by-side.

Description of the Invention (Detailedly, the known hydraulic entangled composite materials have good absorption properties , But is usually too hard, too thin, and flat (such as lack of texture), so it has been found that it can be improved by printing an adhesive material on at least one side of the composite and pressing the fabric to form a texture. Another important What happened was that the process of the present invention was discovered accidentally, which not only increased the softness, but also had no adverse effect on the strength of the woven fabric compared with similarly made composite materials. In some applications, the woven fabric The strength of the cloth is actually increased. The fiber binding force has also been found to be good. This phenomenon can lead to greater friction resistance and lower off-line. When the composite fabric is performed such as by maintaining fibrous properties When mechanically softening the sensitization process that combines the material with continuous long fiber composition, better fiber binding also helps the performance of the composite fabric. Now referring to Figure 1, it shows an excellent anti-hydraulic entanglement used to make composite materials Process. A hydraulically entangled composite material, for example, includes a fibrous composition such as thuja and a nonwoven layer of substantially continuous fibers such as described in US Patent No. 5,389,202 to Everhart: et al.

If it is quite necessary to avoid reaching the polymer composition in non-woven fabrics (usually Including the temperature at which polyolefins such as polypropylene melt, a curing control agent may be added to the latex matrix to allow the mixture to cure at ambient temperature, which is much lower than the polymer in the nonwoven fabric The temperature at which the composition melts. This curing process can be triggered by the disappearance of volatile bases in the formulation. Variants of latex polymers with internal curing agents can also be used. If all the ingredients are added, the viscosity is not In an appropriate range of printing and dyeing, viscosity improvers or additional water can also be part of the formulation. Latex polymer systems acceptable for use in the present invention should be bridgeable at room temperature or slightly elevated temperatures It is stable under the weather conditions of the garden, and has elasticity when cured.

Description of the invention (The pigments that are acceptable for use in the present invention (if pigments are required) must be compatible with the latex and bridging agent used. Generally speaking, pigments have a particulate color Instead of a liquid cross-section like a dye. Commercially available pigments used in the present invention include those manufactured by San doz Chemical, Inc. of Charlotte, North Carolina under the trade name GRAPHTOL®. Products. Special pigments include GRAPHTOL® 1175-2 (red), GRAPHTOL® 6825-2 (blue), GRAPHTOL® 5869-2 (green), and GRAPHTO ② 4534-2 (yellow). Combinations of various pigments can be used to provide a wide variety of colors. In addition to or possibly replacing certain pigments, fillers such as clay can be used as extenders. Clay seems to reduce the fastness of dyeing of the mixture and of course will not provide all the colors of the pigment, but it is less expensive than pigment 'and it represents a cost savings. For example, clay that may be used is Ultrawhite 90 from Engleharrd Corp., 1010 Forest Avenue, Esseling, PO Box 08830, New Jersey. A useful hardening control agent should cause or cause bridging of the latex polymer in the mixture. Ideally, the curing control agent should allow the latex matrix mixture to cure at room temperature or a slightly higher temperature without the need to heat the composite to a temperature at which it begins to melt because it is to be cured. The curing agent may be activated by a certain acid-base rhenium, which is usually neutral or acidic. Therefore, the bonding mixture usually keeps the acid-base rhenium above 8 when it is mixed and applied. Before curing, the acid hydrazone is kept above 8 by using a volatile base such as ammonia. Volatile alkali will remain in the solution until it is driven out of the liquid skeleton at room temperature or changed. Heat them to increase the evaporation rate.

Aprils J999 77 & 5. Description of the invention (3¾ The change is that if necessary, additional processing steps can be performed on the woven fabric. It has been carefully considered. The sensitization process can increase a relatively high degree of stretchability to the woven fabric. As a result, the woven fabric will have a high degree of tissue texture, which will enhance the ability to wipe, wash and / or clean. ❶Variably, many structures and extensibility can be removed from the sheet by stretching or pulling apart the sheet. It disappears. This can be done immediately after sensitization or it can be done on a rewinding operation or similar. The stretched or pulled sheet will have a smooth, soft surface that makes the wipe easily conform to various surfaces. In one embodiment, the woven fabric can be calendered and then treated with a friction reducing agent to provide a treated wiping product with a smooth, low-friction surface. However, it should be understood that if the woven fabric is to be retained as much as possible, When bulking, the calendering step can be deleted from the manufacturing process. Antifriction mixture can be sprayed on the surface of the woven fabric or it can be printed and dyed with lithograph printing and 2 water trays. On woven fabrics. Anti-friction mixtures can be applied to one or both sides of the woven fabric. Once applied to the woven fabrics, the anti-friction mixture will increase the surface smoothness of the fabric and reduce friction.

After spraying the antifriction mixture, the fabric may be fed into Dryer Medium. For example, an infrared dryer to remove residual moisture in the fabric. The fabric can then be rolled into a roll of material and sent to other areas and cut into thin sheets of general size for packaging into wipes. According to The tissue-based composite nonwoven material produced by the above-mentioned process can provide many advantages and benefits over the wiping products made in the past. A more special advantage is that the wiping products of the present invention can have the appearance and touch of a textile product. Compared with the traditional non-structured hydraulically entangled composite material, the structural material of the present invention has more compliance and stretchability. This structural material can also provide better wiping power due to the texture of the structure or Detergency. Moreover, better fibrous material restraint or adhesion also provides greater friction resistance, lower fluff, and better strength. Furthermore, the structural composite material of the present invention has improved the wet bulk due to the texture of the tissue and latex printing. The basis weight of the softened hydraulically entangled nonwoven composite material made according to the present invention can generally range from about 20 to 200 grams per square meter (gsm), and more particularly from about 35 to 100 per square meter.
