Abstract

The invention discloses a method for testing the water absorption capability of an inverted triangle fabric. The method comprises the following test steps: 1) tailoring into isosceles right triangles by taking a warp direction and a weft direction of to-be-tested fabric as the right-angle edges, wherein the right-angle edges are 300mm long; 2) fixing a long edge of the inverted triangle fabric on a core-absorbing test rack, keeping the long edge horizontal and suspending in an inverted triangle; 3) soaking the triangular right-angle part into a colored water solution, and beginning to time, wherein the height soaking below the liquid surface is 30mm; 4) removing the colored water solution after 30 minutes, measuring position data of the infiltration juncture of the colored solution on the fabric; and 5) measuring the core-absorbing height and the diffusion area of water. The method has the beneficial effects of being easy to test and stable in test result; (2) the core-absorbing height under the action of the radial direction, the weft direction and the wrap direction together is tested one time; (3) the diffusion area of liquid water of the fabric in the vertical state can be tested.

Description

Inverted triangle Fabric Wetting Characteristics method of testing

Technical field

The invention relates to the method for testing of Fabric Wetting Characteristics, especially about a kind of method of testing of inverse triangle type vertical wicking method test fabric water absorbing properties.

Background technology

Water absorptivity is one of critical function of fabric.Existing Fabric Wetting Characteristics method of testing is mainly vertical wicking method and drop horizontal proliferation method.Vertical wicking method is the cloth of fabric respectively being cut to 30 mm wides along warp-wise and broadwise, then the lower end of cloth is immersed in liquor potassic permanganate, after 30 minutes, measure the height being diffused on cloth cover from liquid level to liquor potassic permanganate, obtain the measure wicking height of this direction.The method is simple, and result good stability is Fabric Wetting Characteristics method of testing the most widely.But utilization the method, can only obtain a test data in direction at every turn, and cannot obtain the water absorbing properties index of fabric under filling yarn interleaving effect impact.Whether completely drop horizontal proliferation method is that a droplet is dropped on the fabric of horizontal positioned, constantly observe drop diffusion, after drop spreads completely, measures length, width and area that drop spreads vestige on fabric.The method can obtain fabric at the comprehensive characteristic index under weft yams and fabric structure impact.But, use the method to need the continuous whether completely diffusion of drop of observing, from test of many times, subjectivity is very large, simultaneously because the area of diffusion itself is very little, and is subject to the impact of droplet size, and test error is large, so the method utilization is less.

Summary of the invention

The present invention overcomes existing technical deficiency, propose a kind of by adopting sample inverted triangle to hang the disposable measure wicking height recording under warp-wise, broadwise and filling yarn interleaving effect of water sucting mode, and the method for testing of fabric diffusion area of aqueous water under plumbness.

The present invention is achieved by following technical solution:

Taking the warp-wise of fabric to be measured and broadwise as right-angle side, be cut into equilateral right-angle triangle; 2) the long limit of triangle fabric is fixed on wicking testing jig, and makes long limit maintenance level, be inverted triangle and hang; 3) colored water solution is immersed in position, leg-of-mutton right angle, and start timing, the height under immersed in liquid level is 30 millimeters; 4) after 30 minutes, remove colored solutions, and measure the position data of colored solutions infiltration intersection on fabric; 5) measure measure wicking height and wicking diffusion area.

The invention has the beneficial effects as follows: (1) test is simple, and test result is stable; (2) the disposable measure wicking height recording under warp-wise, broadwise and longitude and latitude acting in conjunction; (3) can record fabric under plumbness, the diffusion area of aqueous water.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

Embodiment

Sample to be tested fabric: warp-wise is 130S/2 cotton yarn, broadwise is 67S/1 cotton yarn, 65 × 35 pieces/centimetre of density, color is white;

Fabric to be measured is removed to selvedge, as shown in Figure 4, taking warp-wise and broadwise as right-angle side, on former cloth 44, be cut into equilateral right-angle triangle sample 43, the right-angle side length of side is 300 millimeters, and mark warp-wise and broadwise draw center mark line 42 and water surface boundary sign line 41 on triangle fabric to be measured, so that measurement data, wherein summit, water surface boundary sign linear distance right angle is 30 millimeters and is parallel to the long limit of wedge test piece;

As shown in Figure 1, the long limit of triangle fabric sample 11 is fixed on wicking testing jig 12 with fixing clip 15, and makes the long limit maintenance level of sample 11, be inverted triangle and hang, hang two miniweights 14 in square position, to ensure the smooth of fabric;
