Abstract
The present invention relates to hollow synthetic bristles, a method of making the same, and a paint brush including the same, the method comprising: arranging a first end of said hollow synthetic bristle (1) in a holder; immersing a portion of the second end of the hollow synthetic bristle in a chemical sharpening fluid; lifting the hollow synthetic bristles from the chemical tapering fluid after a period of time, wherein the portion of the hollow synthetic bristles immersed in the chemical tapering fluid is 1-30% of the length of the hollow synthetic bristles.
Description
Technical Field
The present invention relates to a method of making hollow synthetic bristles, hollow synthetic bristles and a paint brush comprising a plurality of such hollow synthetic bristles.
Background
Synthetic bristles, i.e., monofilaments, can be made from various thermoplastic polymers in various configurations (including solid and hollow) and various cross-sections (including round, oval, triangular, three-chamber, four-chamber, lobed), or can include a plurality of gaps. Much work has been done in the industry to improve paint pick-up and paint release of paint brushes by experimenting with a mix of different polymers, configurations and cross-sections.
It is known that natural fibers having split ends retain the coating more effectively and that a plurality of small hairs at the tip portion of each bristle are used to form a finer, smoother surface treatment.
Hollow paint brush synthetic bristles are becoming increasingly popular because they have good paint pickup. However, hollow synthetic bristles that provide a combination of similar efficiency as natural fibers with respect to retaining the coating and forming a more detailed surface treatment have not been satisfactorily achieved.
Disclosure of Invention
The surface treatment or machining, i.e. the tapering, of the tip portion of the synthetic bristle may be achieved mechanically or chemically. Mechanical sharpening may be achieved by passing the bristles through a rotating grindstone. Chemical tapering can be achieved by dipping the ends of the bristles or bundles of bristles into a chemical tapering fluid, such as caustic or acid, to a certain bristle and/or bundle depth.
By "tapering" is hereby meant, throughout the present text, any machining or surface treatment suitable for application to the tip portion of a synthetic bristle, such as tapering and marking (flagging).
It is generally known in the art that hollow synthetic bristles cannot be satisfactorily sharpened by chemical sharpening due to capillary action drawing the chemical sharpening fluid into the uncontrolled interior depth of the hollow synthetic bristles. A disadvantage of mechanical sharpening is that hollow synthetic bristles are susceptible to damage when subjected to known commercial sharpening devices.
Furthermore, it is generally known that paint brushes with synthetic bristles are easier to clean and generally less expensive than paint brushes with natural fibers.
It is therefore an object of the present invention to overcome the disadvantages of the prior art, such as those indicated above.
It is another object to provide improved hollow synthetic bristles for paint brushes having a satisfactory pointed portion that mimics to a greater extent natural fibers having split ends.
It is a further object of the present invention to provide a process for making a satisfactory pointed portion of a hollow synthetic bristle.
It is a further object of the present invention to provide superior paint brush synthetic bristles with improved paint pick-up and paint release and resulting in a fine and smooth surface treatment.
It is another object of the present invention to provide synthetic bristles for paint brushes having optimized performance/characteristics, such as in terms of customized stiffness, i.e., lower stiffness at their tips and higher stiffness closer to their roots.
It is another object of the present invention to provide tapered and/or marked synthetic bristles which are useful in the manufacture of paint brushes and which have improved paint pick-up, paint release, and which form a fine and smooth surface treatment.
It is another object of the present invention to provide a method of chemically marking/abrading free ends of hollow synthetic bristles such that their free ends are "fully" i.e. not too much or too little marked/rimmed. Thus, after completion of the process, their free ends comprise an optimized shape and/or number and/or size of useful split ends/abrasions, the split ends being two, three or more smaller and/or tiny ends at the free end portion of each hollow synthetic bristle, and for providing such inventive hollow synthetic bristles for making a paint brush. In principle, the method according to the invention breaks and tears the free ends of the hollow synthetic bristles by chemically splitting/separating them from one larger free end into more and smaller free ends. These hollow synthetic bristles, each comprising a multi-tipped free end, i.e. a free end comprising at least two "micro" tips instead of only one "macro" tip, achieve improved paint pick-up, paint release and a fine and smooth surface treatment.
According to the present invention, there is provided a method of making hollow synthetic bristles for a paint brush, wherein the method comprises: disposing a first end of a hollow synthetic bristle in a holder; immersing a portion of the second end of the hollow synthetic bristle in a chemical sharpening fluid; the hollow synthetic bristles are lifted from the chemical tapering fluid after a period of time, wherein the portion of the hollow synthetic bristles immersed in the chemical tapering fluid is 1-30% of the length of the hollow synthetic bristles.
Surface treatment or machining of the free or second end of the hollow synthetic bristles is thereby provided, including chemical tapering of between 1-30% of the length of the hollow synthetic bristles.
Further provided is a surface treatment or finish wherein a portion of the second end of the hollow synthetic bristle is finished on both its inside and outside.
In the context of the present invention, the term "bristle" should be understood as an elongated flexible body having a first end and a second end. The first end is a part of the root where the bristles may be received and/or secured in the bristle carrier. The second ends of the bristles form free tips that are generally in contact with the surface to be coated with the coating. The second end is part of the tip portion of the bristle.
The hollow synthetic bristles may be made from a variety of thermoplastic polymers, such as polyamides, polyesters, and polyolefins.
The cross-sectional area of the hollow synthetic bristles may be cylindrical or elliptical or S-shaped, and the hollow synthetic bristles may have a substantially uniform wall thickness along the length of the synthetic bristles prior to chemical tapering.
The hollow synthetic bristles may be between 40-100mm in length.
The hollow synthetic bristle may comprise one or more longitudinal cavities extending from an opening in the free or second end of the synthetic bristle towards the first end of the synthetic bristle. The one or more longitudinal cavities may extend along a portion of the length of the synthetic bristle or along the entire length of the synthetic bristle, such that the synthetic bristle is partially hollow along its length or hollow along its entire length similar to a tube. Furthermore, the one or more longitudinal cavities may, but need not, be precisely aligned with the central axis of the synthetic bristle. Such cavities may also extend at an angle relative to the longitudinal extension of the synthetic bristle and the extension of the central axis.
Experiments have shown that by applying chemical tapering to the shorter ends of synthetic bristles, a method is provided that allows the use of chemical tapering on hollow synthetic bristles, as compared to the conventional practice of using a tip portion of typically about 25mm or up to 50% length prior art bristles when chemical tapering is used on solid bristles, since the problem of capillary action drawing the tapering fluid into the uncontrolled internal depth of the synthetic bristles is avoided. Experiments have also shown that hollow synthetic bristles in some aspects allow the coating to "leave" the interior of its cavity due to the coating not being completely at least not circumferentially enclosed, and thus uncontrolled pumping and/or capillary effects are reduced. This is due to the fact that the hollow synthetic bristles after treatment according to the invention are at least in some aspects partially open along their envelope surface of their free ends, so that the coating is less strongly "attached" to the free ends, i.e. the capillary action does not have the "grip"/capillary holding effect of the coating as strong as in the prior art so far.
Hollow synthetic bristles having a satisfactory pointed portion are thereby provided. The pointed portion corresponds to a portion of the second end of the hollow synthetic bristle that is immersed in the chemical pointing fluid.
In addition, the chemical tapering reduces the wall thickness of the hollow synthetic bristle on its outer and inner surfaces. The reduced wall thickness thereby achieved by tapering the outer surface of the hollow synthetic bristle provides a tapered synthetic bristle. Thus, the reduced wall thickness achieved by tapering the inner surface of the hollow synthetic bristle also provides a larger hollow cavity within the tapered portion of the synthetic bristle for accommodating increased paint pick-up capability.
Furthermore, chemical tapering marks the pointed portion of the hollow synthetic bristles as multiple split ends or tips, which accommodates increased paint pick-up, paint release capability, and creates a fine and smooth surface treatment.
In principle, the method according to the invention breaks and tears the hollow synthetic bristles by chemically splitting/separating them from one larger free end into more and smaller free ends. These hollow synthetic bristles each include multi-tipped free ends, i.e., free ends that include at least two "micro" tips rather than just one "macro" tip.
In one aspect of the invention, the portion of the hollow synthetic bristles immersed in the chemical tapering fluid is 10-30%, 10-25%, or 10-20% of the length of the hollow synthetic bristles.
In another aspect of the invention, the length of the portion of the hollow synthetic bristles immersed in the chemical tapering fluid is 1-20mm, 5-15mm or about 10mm.
In yet another aspect of the invention, the chemical sharpening fluid comprises sodium hydroxide (NaOH). The method may thus comprise applying a chemical tapering fluid, which may be sodium hydroxide, to the portion of the second end of the hollow synthetic bristle.
The chemical sharpening fluid may be a sodium hydroxide solution or any other suitable caustic that is highly soluble in water to produce a caustic solution. The sodium hydroxide solution may comprise 30-40% sodium hydroxide and 60-70% water and be heated to about 100 ℃.
Chemical tapering may be provided by immersing a portion of the second end of the hollow synthetic bristle one or more times in a chemical tapering fluid, such as a sodium hydroxide solution.
Chemical tapering may be provided by immersing portions of the second end of the hollow synthetic bristle in a chemical tapering fluid at varying depths/distances during the time duration in the tapering fluid. The impregnated portion of the second end of the hollow synthetic bristle may be lifted and lowered into the tapering fluid at different time rates and/or speeds and/or in steps. The impregnation may be maintained at different depths and with varying durations at each depth, or stepwise and with varying depths, and/or at each step for the same or different durations.
In another aspect of the invention, the wall thickness of the hollow bristles is between about 0.05-0.1mm and/or between 0.05-0.1mm.
The chemically pointed portion of the second end of the synthetic bristle may comprise a thinner wall thickness than the non-pointed remainder of the synthetic bristle.
The hollow synthetic bristles may be dipped into a chemical sharpening solution, such as a sodium hydroxide solution, preferably for between 30-60 minutes and/or for about 30 minutes and/or for about 60 minutes or more or less.
In one aspect of the present invention, the hollow synthetic bristles are lifted from the chemical sharpening fluid after a period of time in which portions of the hollow synthetic bristles are partially decomposed in the chemical sharpening fluid.
In another aspect of the invention, the hollow synthetic bristles are lifted from the chemically tapering fluid after a period of time in which the longitudinal portions of the hollow synthetic bristles are broken down in the chemically tapering fluid and the second ends of the hollow synthetic bristles have two or more tips.
In yet another aspect of the present invention, the period of time is such that 1-30% of the portion of the hollow synthetic bristle immersed in the chemical sharpening fluid is decomposed in the chemical sharpening fluid.
In one aspect of the invention, the method further comprises immersing the second end of the hollow synthetic bristle in water after lifting the hollow synthetic bristle from the chemically tapering fluid.
In another aspect of the invention, the hollow synthetic bristles are hollow polyester bristles.
In yet another aspect of the present invention, the method further comprises the step of drying the hollow synthetic bristles.
The invention also relates to hollow synthetic bristles obtained by the above process.
The present invention also relates to a paint brush comprising a plurality of hollow synthetic bristles as described above. Paint brushes with improved paint pick-up and paint release are thereby provided.
The paint brush may include a handle, a bristle carrier, and a plurality of bristles attached to the handle by an adhesive and/or the bristle carrier and/or any other suitable fastening means.
The paint brush may include a mixture of different types of natural and/or synthetic bristles, wherein the first type of synthetic bristles are hollow synthetic bristles, as described above.
The different types of bristles may include solid and hollow bristles or partially solid/hollow bristles of various cross-sections, including circular, elliptical, four-chambered, three-chambered, lobed, and/or may include multiple gaps, corrugations, and/or surfaces having other configurations. Further, the different types of bristles may include mechanically and/or chemically pointed bristles.

Detailed Description
The present invention relates to a hollow synthetic bristle 1 for use in a paint brush (not shown) with several other synthetic bristles, which may be the same, similar or different, as a plurality of synthetic bristles or a bundle of synthetic bristles or a synthetic bristle mixture with at least one, preferably more than one, such hollow synthetic bristle of the present invention, and to a paint brush comprising a plurality of such synthetic bristles 1. The invention also relates to a method of forming/shaping a synthetic bristle 1, i.e. at least a portion of its free end, i.e. its second end.
Fig. 1 a-1 b show a synthetic bristle 1 according to the present invention. Referring to fig. 1a, there is shown a chemically tipped hollow synthetic bristle 1 according to the present invention, wherein the synthetic bristle 1 is divided into a portion 2 at the second end (i.e., the tipped portion) and a remaining portion 4 (i.e., the non-tipped portion), the remaining portion extending from the first end (not shown) of the hollow synthetic bristle towards the portion 2 at the second end. The tapering portion 2 extends from the non-tapering remaining portion 4 towards the opening 5 of the second end. The pointed portion 2 is part of the free end of the hollow synthetic bristle 1. The hollow synthetic bristle 1 may be a tubular synthetic bristle 1 comprising a longitudinal cavity 6 extending from an opening 5 along the length of the synthetic bristle. The longitudinal cavity 6 may be cylindrical as in the presently illustrated aspect, or have any other suitable shape. The longitudinal cavity 6 may, as in the presently illustrated aspect, be an internal cavity extending along the length of the synthetic bristle. If the cross-section of the hollow synthetic bristle 1 is oval, the longitudinal cavity 6 may have a corresponding oval shape. The hollow synthetic bristle 1 may be made of polyester and the non-tipped remaining portion 4 may have an outer diameter of between 0.2-0.4 mm. The pointed portion 2 of the second end of the synthetic bristle comprises 1-30%, or 10-25% of the total length of the synthetic bristle 1. Alternatively, the pointed portion 2 of the second end of the synthetic bristle 1 comprises 10-20% of the total length of the synthetic bristle. The wall thickness of the non-tipped remaining portion 4 may be between 0.05-0.1mm and the wall thickness of the tipped portion 2 of the second end may be between 0.05-0.1mm. In some aspects, the wall thickness of the tapered portion 2 of the second end is less than the wall thickness of the non-tapered remaining portion 4.
Referring to fig. 1b, there is shownbase:Sub>A cross-sectionbase:Sub>A-base:Sub>A of the chemically tipped hollow synthetic bristle 1 of fig. 1base:Sub>A wherein the chemical tipping applied reduces the wall thickness of the inner and outer surfaces of the tipped portion 2 of the second end of the hollow synthetic bristle 1. Thereby providing a tapered synthetic bristle 1 having a longitudinal cavity 6, the cross-sectional area of the bristle wall of which decreases in the tapering portion 2 of the second end of the hollow synthetic bristle immersed in the chemically tapering fluid. The cross-sectional area of the cavity 6 is greater in the tapered portion 2 of the second end of the hollow synthetic bristle 1 than in the non-tapered remainder 4 of the hollow synthetic bristle 1, with the cross-sectional area of the cavity 6 being greatest at the opening 5. The pointed portion 2 of the hollow synthetic bristle 1 may transition into the non-pointed remaining portion 4, i.e. as seen in a direction from the second or free end and its opening 5 towards the non-pointed remaining portion 4 of the hollow synthetic bristle 1.
Referring to fig. 2, there is shown a marked chemically tipped hollow synthetic bristle 1 according to the present invention, wherein the hollow synthetic bristle 1 is provided with a plurality of split ends or tips 7. The tip 7 is provided by chemically tapering the fluid to cause the longitudinal portion to break up along the length of the hollow synthetic bristle 1 in the second end of the hollow synthetic bristle 1.
When chemically pointed, i.e. when applying the method of manufacturing hollow synthetic bristles 1 according to the present invention, the pointed portion 2 of the second end of the hollow synthetic bristle 1 may be tapered and marked. In some aspects, chemical marking or cutting or slicing "apart" of the pointed portion 2 into more than one small end or tip 7 is achieved in principle due to the fact that chemical pointing erodes through the wall of at least a portion of the pointed portion 2, i.e. the "pit depth" formed by the erosion exceeds its wall thickness.
Referring to fig. 3, steps a-D of a method of making hollow synthetic bristles 1 according to the present invention are illustrated, wherein a first step a comprises disposing a first end (not shown) of the hollow synthetic bristle 1 in a holder (not shown).
The next step B comprises immersing the portion to be sharpened 2 of the second end of the hollow synthetic bristle 1 in a chemical sharpening fluid, wherein the portion to be sharpened 2 of the second end of the hollow synthetic bristle 1 may comprise 1-30%, or 10-25%, or 10-20% of the length of the hollow synthetic bristle 1. Alternatively, the portion 2 of the second end of the hollow synthetic bristle 1 to be pointed may constitute a length of 1-20mm, 5-15mm, or about 10mm of the hollow synthetic bristle 1.
A next step C includes lifting the hollow synthetic bristle 1 from the chemical tapering fluid after a period of time, wherein the period of time may be between 30-60 minutes and/or about 30 minutes and/or about 60 minutes or a period of time that is more or less.
Steps D and E are both optional steps, wherein one or both of them may be performed after step C. Step D includes immersing the second ends of the hollow synthetic bristles 1 in water or any other suitable cleaning fluid after the hollow synthetic bristles are lifted from the chemical tapering fluid, and step E includes drying the hollow synthetic bristles 1. Step D is completed to flush or wash away the tapering fluid from the hollow synthetic bristles 1 prior to further use. The purpose of step E is self-evident.
