Du Printing 307802 / V7 by the Shelley Consumer Cooperation Department of the Ministry of Economic Affairs of the Ministry of Economic Affairs _______ V. Description of Invention (1) Application for the customs application This application is a joint application with the application filed on May 16, 1994, which is still pending. U.S. Patent Application 08 / 243,344, and its two partial applications. The scope of the invention The present invention relates to fibers made from thermoplastic polymers containing hard fillers, which have improved resistance to cutting. BACKGROUND OF THE INVENTION Improved resistance to cutting with sharp edges has long been sought. Cut-resistant gloves are advantageously used in the meat packaging industry and in automotive applications. As indicated by US Patent Nos. 4,004,295, 4,384,449 and 4,470,251, and by European Patent No. 458,343, gloves that provide cutting resistance have been made from yarns that contain flexible metal wires or are made of high tensile strength Composed of fibers. A disadvantage of gloves made from yarn and containing flexible metal wires is that the hands are fatigued and cause reduced productivity, and the possibility of increased injury. Furthermore, 'with long-term wear and deflection, the wire may fatigue and break' and cause cuts and wear on the hands. In addition, when the washed gloves are dried at elevated temperature, the metal wire will act as a heat sink, which may reduce the tensile strength of the yarn or fiber, thus reducing the protective effect of the cover and the life of the glove. Highly oriented fibers with high modulus and high tensile strength are more resistant to cutting than conventional semi-crystalline polymers. Examples of these highly oriented polymers include poly (aramidamide), thermotropic liquid crystal polymer, and extended chain paper.

It also has disadvantages that limit its practicality, including loss of properties at the temperature encountered in the dryer (polyethylene), poor resistance to bleach (polyamide), poor comfort, and high cost. Improved flexibility and comfort and uncomplicated laundry operations are desired on cut-resistant, protective clothing. Therefore, there is still a need for a flexible cut fiber that will retain its properties when routinely washed. Such fibers can be advantageously used in the manufacture of protective clothing, especially highly flexible cut-resistant gloves. Thermoplastic polymers mixed with particulate matter have been made into fibers, but this method does not significantly improve the cut resistance of the fibers The only exception is the thermotropic liquid crystal polymer. For example, a small amount of particulate titanium dioxide has been used in polyester fibers as a delusterant. It is also used in polyester fibers. It is a small amount of colloidal silica, which It is used to improve gloss. Magnetic materials have been incorporated into the fibers to produce magnetic fibers. Examples include: Ming / rare earth intermetallic materials in thermoplastic fibers, for example As described in the published Japanese Patent Application 55/098909 (1980); cobalt / rare-earth intermetallic materials in the core-shell fibers or gill ferrite, described in the published Japanese Patent Application 3 -130413 (1991); and magnetic materials in thermoplastic polymers, which are described in the Polish patent 251 452, and κ Ding-et al., J ^ Magn.

The particle size and particle size of the printing and printing of the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs Distribution, gaining good resistance Cutability while preserving the mechanical properties of the fiber is an important parameter. In general, the hard filler should be in the form of particles, and the powder form is generally suitable. Flat particles (meaning platelets) and elongated particles (needles) Matter) can also function well. The average particle size is usually in the range of about 0.25 to about 〇0 microns. The preferred average particle size is in the range of about 1 to 6 microns. The best average particle size It is about 3 microns. For flat (meaning small platelets) or elongated particles, the particle size refers to the length along the long axis of the particle (meaning, the long size of the elongated particles or the surface of the platelet) Diameter) 3 These particles should preferably show a logarithmic normal distribution. In order to make textile fibers (that is, with a weaving dimension of Danny in the range of about 1.5 to 15 dpf), the particles should be considered; The way is to cause particles larger than about 6 microns to be excluded. Use a smaller percentage of hard filler. This amount is selected to produce enhanced cut resistance without causing a significant loss of tensile properties.

This fiber < shoulder properties (tenacity and modulus) are preferably not reduced by more than about 50%. About 25%. The best case is that there is no significant change in tensile properties (that is, a decrease in properties of less than about 10%). On a weight basis, the filler should be present in an amount of at least about 0.01%. The upper limit of the filler is mainly determined by the effect of resisting tensile properties, but above about 20% by weight. Scrap content is usually less desirable.

V. Description of the invention (9) Tensile resistance Tenacity, elongation and modulus are measured using ASTM test method D-3822. Cut resistance The fiber is first knitted into a fabric to test the cut resistance. The density of the yarn in the fabric is measured in ounces per square Code (OSY in Tables! And 2). Then, the Ashland Cutting Performance Protection (MCPP ") test was used to measure the cutting resistance of the fabric. This test was conducted at TRI / Environment Company, 9063 Bee Cave Road, Austin, Texas, at 78733-6201. In this test, the fabric samples were placed on the four sides of the mandrel. A series of tests were carried out in which a variable-weight razor blade was loaded and the fabric was pulled across the fabric until the fabric was completely cut. Measure the distance the razor blade travels across the cloth until the blade completely cuts the cloth. The point where the razor blade cuts through the fabric is the point where electrical contact is made between the mandrel and the razor blade. Plot the distance required to perform this cut as a function of the load on the razor blade. The cutting distance was changed from about 0.3 inches to about 1.8 inches, and the data was measured and plotted. The resulting pattern is roughly a straight line. Draw or calculate through the points on the graph-a logical straight line 'and traverse the fabric by a British pair of strokes. The weight needed to cut the fabric is taken from this graph or calculated by regression analysis. After the blade runs across the cloth for one inch, the insertion value of the weight required to perform a cut is shown in Tables 1 and 2 as "CPP", which is an abbreviation for cutting protection performance. Finally, for comparison For the purpose of different surface density data of cloth samples, divide the cpp value by the cloth surface density (OSY) of the cloth to compensate for the deviation of the cloth density. In Tables 1 and 2, this value is based on CPP / OSY Example 2 In these experiments, the PET fiber sample was filled with alumina powder, which is ___________- J2 -__ This paper scale Laijinguanjia County (CNS) A4—Specifications ::--~~- -I j-1 ^ 1 ^^^ 1 .i ^^^ 1 II i 1 1 OJ--1 = 1 ^ 1 n (Please read the note on the back of 5t and then fill out this page) A.7 __ — _ _ V.

It uses two different alumina powders with an average particle size of about 0.05 microns and about 10 microns. Cohesive powder, available from Buehler Company (Waukegan Road, Lake Bluff, Illinois 60044). 0.05 micron alumina is r alumina, which has a cubic crystal structure and Mohs The degree value is 8.] The micrometer material is alpha alumina, which has a hexagonal crystal structure, and the Mohs hardness value is 9 ^ Using the same method as in Example 4, 'two alumina powders are blended with ρΕΤ, and obtained The filled PET sample contains alumina with a content of about 021%, 〇 %%, 1.9% and 2.1% by weight. Using the same method as in Example 1, the fiber properties and cutting resistance are measured. The data is It is presented in Table 2. The data in Tables 1 and 2 show that the improvement in cutting resistance at all field materials used in these experiments is at least about 10% to 2%. Two sets of data The filler is incorporated into the fiber at a content of about 0.070 / 0 to about 0.7% on a volume basis. With these amounts and particle size, the fiber properties do not show a significant decrease.

The calibration standard is 0062-inch poly gas butadiene NS-5550. From FAIRPRENE (85 Mill Plain Road, Fairfidd, CT 06430), it has a CPP value of 400 grams. This CPP value is measured at the beginning and end of a series of tests, and the average normalization factor is calculated. This will result in a measured standard CPP value of 400 grams. Then, use this normalization factor to correct the data measured by the series of trials. Moreover, when calculating the CI > p value, a logarithmic graph of the distance required to cut the fabric against the load on the razor blade is used because it is more linear. A series of experiments were conducted using burnt alumina as the filler of the fiber. These experiments were performed using the same procedure as the user in Example 1_3 'but using a wider particle size (0.5_3 microns) and a wider range of concentration (0.8-3.2 volume./.)
