(2) Moisture content According to JIS L 1015 (2010), the measurement is carried out at a temperature of 20°C and a relative humidity of 65%. (3) Number of fluff Measured according to JIS L 1095 (2010) 9.22.2 B method. As a fluff tester, F-INDEX TESTER (Shikishima Textile Co., Ltd.) was used, and the test conditions were set to a line speed of 30 m/min, a test length of 10 m, and N=30. (4) British cotton count It is measured in accordance with the cotton count measurement method of JIS L 1095 (2010) 9.4.1 of general textile thread (corrected mass), tex and count measurement. (5) Twist coefficient The twist number is measured according to JIS L 1095 (2010) 9.15.1A method, and the twist coefficient is calculated by the following formula. Twist coefficient = number of twists per 1 inch of thread length/√ count (6) Twist angle (A) Place the wire in the horizontal direction and use the electron microscope VE-9800 manufactured by KEYENCE to obtain an image of the side of the wire (100 times). (B) Obtain the midpoints of the cross-sectional direction of the line at the left and right ends of the acquired line's profile image, and connect the two points with a straight line to obtain a spool. Use the obtained spool as the reference line. For example, in FIG. 4, C and D are the midpoints of the cross-sectional direction of the left and right ends of the line's profile image, and Lb is the reference line. (C) Measure the acute angle between the reference line and the fiber on the surface of the twisted thread, and use it as the twist angle. For example, in FIG. 4, the acute angle α formed by the reference line Lb and the fiber on the surface of the line is the twist angle. Find the lay angle at 5 randomly selected places, and find the average value of them. (7) Porosity and apparent density (I) Calculate the diameter of the textile thread based on the side view of the thread For the side of the thread, take the electron microscope VE-9800 (magnification 40 times to 100 times) manufactured by KEYENCE to take the side surface of the thread without tension. For example, as shown in Figure 5, with respect to the outermost fiber of the line at any position of the line (hereinafter, the outermost fiber), a tangent line is drawn in the length direction of the line, and the perpendicular to the tangent line is relative to the line The central axis (length direction) is lowered vertically. Set as the intersection A between the perpendicular line and the outermost fiber of the constituent line. Furthermore, the center axis of the sandwiching line is set to the intersection B of the outermost fiber on the opposite side of the intersection A. Determine the diameter of the line based on the distance between AB. Take 5 images of different places on 1 sample. For each image, 5 wire diameters were calculated and set as the representative value of the image. Furthermore, the average value of 5 images was calculated|required as the representative value of the line sample. (II) Calculate the apparent density of the textile thread Use the diameter of the textile thread measured according to the metric count (JIS L 1095 9.4.1 metric taxi and count) to calculate the weight per unit length (I), to approximate the cross section of the thread to a circle The calculated volume is divided by the weight per unit length to define the apparent density of the line. The smaller the apparent density, the larger the volume per unit length of the line. For the cross-section of the wire, in order to save the cross-sectional shape, it was embedded with a microtome (Leica EM UC6) and trimmed with a glass knife, and photographed with the electron microscope VE-9800 (270 times magnification) manufactured by KEYENCE . (III) Calculation method of porosity Calculate the volume Vm of any cylinder with the same specific gravity as the fiber material constituting the thread and the same weight as the thread. Furthermore, using the wire diameter measured in (I), the cross section of the wire is approximated to a circle to calculate the wire volume Vy. If Vy is divided by Vm and multiplied by 100, the ratio of the volume occupied by the fiber in the thread is obtained. By subtracting this ratio from 100, the porosity is derived as the ratio of the air in the line. Among them, the fiber specific gravity described in JIS L 1096:2010 8.11 Apparent Specific Gravity and Pore Volume Ratio is used in the calculation. (8) Pilling ball test Based on the JIS L 1076 A method, use an ICI-type testing machine to conduct a pilling test to confirm the degree of pilling. (9) Fiber properties According to JIS L 1015, measure the strength and elongation of monofilament fibers. (10) Weight per unit area, thickness and overall density The weight per unit area and thickness are measured in accordance with JIS L 1096 (2010). The overall density is calculated based on the weight per unit area and the thickness. (11) The productivity of the weaving process Based on the following 5 grades, each step in the weaving step ((I) blending cotton, (II) carding, (III) drawing, (IV) woolen spinning, (V) worsted spinning, (VI) winding ) Is evaluated on the productivity, and its average score is used as the comprehensive score. 5: good 4: Generally good 3: Normal 2: More problems 1: Unable to produce (12) Weaving of cloth The knitability of the fabric was evaluated based on the following 5 levels. 5: good 4: Generally good 3: Normal 2: More problems 1: Unable to produce (13) Water absorption and quick drying According to the evapotranspiration (II) test (BOKEN standard BQE A 028) of the BOKEN quality evaluation agency, the evapotranspiration rate after 20 minutes is calculated. BOKEN general product benchmark is more than 30%. The evapotranspiration rate is specifically measured and calculated by the following method. (A) Determine the mass (W) of the test piece and petri dish with a diameter of approximately 9 cm. (B) Add 0.1 mL of water dropwise to the petri dish, place the test piece on it, and measure the total mass (W0). (C) Place it in a standard state (20°C, 65%RH), measure the total mass (Wt) per prescribed time, and calculate the evapotranspiration rate (%) after 20 minutes. Evapotranspiration rate (%)=[(W0－Wt)/(W0－W)]×100 (14) Thermal insulation Using Thermo Labo II manufactured by Jiaduo Technology Co., Ltd., the heat retention rate was measured by the dry touch method to evaluate the heat retention. Specifically, under a certain air flow (30 cm/s), measure the heat dissipation rate (power consumption) of a hot plate set to ambient temperature + 10°C through a test piece (20×20 cm) to obtain the heat preservation rate. The larger the number of heat preservation rate, the more it is judged as higher heat preservation. (15) Wind resistance Using the KES-F8 air permeability testing machine manufactured by Jiaduo Technology Co., Ltd., a constant flow of air is sent to the sample by the piston movement of the cylinder to release and attract the sample to the atmosphere. The semiconductor differential pressure is used Measure the pressure loss caused by the sample within 10 seconds.
