preparation example Construction

[0033] The steps of the preparation method of the yarn fluffing and pilling milled yarn cylinder filled with the above-mentioned high polymer are as follows:

[0034] The first step is to engrave and grind the metal cylinder. The outer surface of the metal cylinder 2 is engraved with directional wear marks 3 with a depth and spacing of 20 μm to 2 mm, wherein the directionality refers to one of parallel, orthogonal, and diamond-shaped wear marks, and the wear marks 3 The protruding point can rigidly insert or withstand the yarn 7, while the concave part can rigidly hold the yarn 7 and restrict the yarn 7, with more contact surfaces and holding points, and at the same time when the thicker scuff marks 3 , it can take into account that the parallel scratch marks 3 can provide the effect of simulating the fabric structure, while the vertical thicker scratch marks 3 can prevent the yarn 7 from shifting and rolling.

[0035]The second step is to scrape the polymer. The solvent-sol...

Embodiment 1

[0039] Adopt the preparation method of the present invention to obtain the yarn cylinder that the surface engraved rhombus direction, lateral depth and spacing are 1.5mm, oblique depth and spacing are 200 μm, and then scrape coating the polyurethane solution with a thickness of 1mm and solidify to form a film, its surface forms The surface structure is composed of rigid and flexible components filled with flexible polymers in the rigid scratches. The double-strand yarn of full wool with a yarn number of 16.4tex and 2×8.2tex is wound on the bobbin with a tension of 6cN. On the surface, the winding yarn 7 is rigidly restricted by the protruding part of the scuff marks in the pilled scuffed yarn, and is held by a large area due to the flexible depression of the solvent-soluble polymer scraped in the scuff marks. There is no movement and tumbling, which can make the grinding yarn of the winding layer more stable and applicable to a wider range. There is no dislocation and overlapp...

Embodiment 2

[0041] Adopt the preparation method of the present invention to obtain the yarn bobbin that the surface is engraved in the orthogonal direction, the depth and the distance are all 700 μm, and then the rubber solution with a thickness of 500 μm is scraped and solidified to form a film, and the surface forms a flexible high polymer filled with rigid engraving The surface structure of rigid and soft components in the traces is combined. The wool acrylic blended yarn with a yarn number of 11.1tex is wound on the surface of the bobbin with a tension of 9cN. Restricted by the rigidity of the protruding parts of the scratches, and the flexible depression of the rubber coated in the scratches produces a large area of ​​grip without moving and rolling, which can make the grinding yarn of the winding layer more stable and suitable for the surface wider. There is no dislocation and overlapping of the winding yarn 7 in the whole close-packed winding. The friction along the axis of windin...

Abstract

The invention relates to a high-polymer fuzzing and pilling yarn grinding cylinder with grinding cracks and a preparation method and function of the high-polymer fuzzing and pilling yarn grinding cylinder. Firstly, parallel or orthogonal or rhombic grinding cracks are formed on the surface of the yarn grinding cylinder through directional grinding, the depths of the grinding cracks range from 20 micrometers to 2 millimeters, the distance between every two adjacent grinding cracks is the same as the depth of each grinding crack, then blade coating is carried out on solvent-soluble high-polymers, after solidification, flexible high-polymers are formed and are injected into a composite surface structure of a rigid grinding crack groove, and accordingly wound yarn wound on the outer layer of the yarn grinding cylinder is under rigidity limit of protruding portions of the grinding cracks in the fuzzing and pilling ground yarn and meanwhile is held in a large area due to flexible pressing of the high-polymers and cannot move or roll, and the measurement result is more stable. The yarn grinding cylinder comprises a yarn cylinder shaft, a metal cylinder body with the grinding cracks, a high-polymer blade coating layer, embedded grooves in two sides, a left yarn end nail and a right yarn end nail, is a key component of a yarn fuzzing and pilling measurement device, and can be used for yarn fuzzing and pilling ground yarn sample preparation and measurement.

Description

technical field [0001] The invention relates to a yarn fluffing and pilling grinding drum filled with high polymer wear marks and its preparation and application, which can make the winding layer have rigid and flexible grip, make the grinding process more stable, and is suitable for the production of yarns. It has a wider scope and belongs to the technical field of textile pilling resistance testing and evaluation. Background technique [0002] Up to now, most of the yarn friction instruments are used to test the abrasion resistance of yarns, to simulate the actual friction performance of yarns in the weaving process and in use, rather than to evaluate the pilling properties of yarns and fabrics. For example, the domestic LFY-109 multifunctional yarn abrasion tester, its main disadvantage is its singleness, it can only rub the yarn with sandpaper, and cannot simulate the friction performance during the production process (such as when the yarn passes through the weaving ree...
