preparation example Construction

[0032] The present invention also provides a method for preparing the above-mentioned yarn fluffing, pilling and milling cylinder of imitation fabric structure, the steps of which are as follows:

[0033] The first step is to paste the wire. First, coat the adhesive on the surface of the metal cylinder 2 of the grinding cylinder, then straighten the metal wires 3 with a diameter of 0.1 to 2 mm, and arrange them parallel to the axis 1 of the yarn cylinder at equal intervals of 0.5 to 8 mm, so that the actual The friction part is strengthened and the yarn is not easy to roll and move, so as to replace the characteristic effect of buckling and bulging of the yarn in the interweaving structure of the fabric.

[0034] The second step is to paste the polymer film. The high polymer film 4 has a smooth surface on one side and a rough surface on the other side, with a thickness of 0.1-3mm. It is a polyurethane film or a rubber film. The winding yarn 7 can be stably depressed in the p...

Embodiment 1

[0038] Adopt the preparation method of the present invention to obtain the bobbin of the polyurethane film that is pasted with diameter 0.4mm, equidistant 2.5mm stretched metal wire 3 and thickness on the surface, the wool / polyester filament that yarn number is 18.2tex The composite yarn is wound on the surface of the bobbin with a tension of 8cN. The winding yarn 7 is naturally and stably pressed into the rough polyurethane film on the outer surface and held by its rough surface, and is strengthened by the raised and buckled parts of the metal wire 3 Grind. There is no dislocation and overlapping of the winding yarn 7 in the whole close-packed winding. The whole friction along the axis of the winding yarn 7, the winding yarn 7 has no movement; the friction along the axis of the metal cylinder 2, the winding yarn 7 has no obvious movement and tumbling; the friction of the composite Lissajous curve trajectory of the two, the winding yarn 7 has no Noticeable movement and tumbli...

Abstract

The invention relates to a yarn fuzzing and balling grinding barrel in an imitation fabric structure, as well as the preparation and the application of the yarn fuzzing and balling grinding barrel. In order to allow a wound yarn wound on an outer layer of the grinding barrel to have a buckling structure of a yarn in fabric during grinding, and keep relatively stable grinding, or grinding with little movement or without movement, metal wires which are arrayed at equal intervals and are parallel to a yarn barrel shaft are bonded on the surface of a metal barrel part of the yarn fuzzing and balling grinding barrel, then the surface of the metal barrel part is coated and bonded with a high polymer film in a certain thickness, and the external surface of the high polymer film is rough. Upheaval of the metal wires allows the wound yarn to be buckled, and the high polymer film can ensure that the wound yarn is pressed in the film stably and gripped by the rough surface of the high polymer film, so that the grinding at a buckling bulge part can be intensified during the grinding, the wound yarn does not roll or move, and fuzzing and balling results of the yarn are more approximate to those of the actual fabric. The grinding barrel comprises the yarn barrel shaft, the metal barrel part, the metal wires, the high polymer film, embedding grooves on the two sides, a right thrum nail, and a left thrum nail, is a critical component of a yarn fuzzing and balling measurement device, and can be used for grinding sampling and measurement of yarn fuzzing and balling.

Description

technical field [0001] The invention relates to a yarn fluffing and pilling grinding cylinder imitating the fabric structure and its preparation and application, which can make the milled yarn of the winding layer closer to the fluffing and pilling characteristics of the actual fabric, and belongs to the test and application of the pilling resistance of textiles. Evaluate technical areas. 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 reed). Also can't simulate the...
