preparation example Construction

[0028] The present invention also provides a method for preparing the above-mentioned yarn bobbin suitable for fluffing, pilling and grinding, the steps of which are as follows:

[0029] The first step, pasting the polymer film 3: first paste the smooth surface of the polymer film 3 with a smooth surface on one side and a rough surface on the other side with a thickness of 0.5-3 mm to the metal cylinder 2 through an adhesive, Its rough surface is used to contact with the winding yarn 6, so that the ground winding yarn 6 is stably depressed in it by the rough surface of the polymer film 3 and held by the rough surface, keeping the winding yarn 6 wound in the outer layer. Stablize;

[0030] The second step, slotting the yarn tube: on the edge corners of the left and right ends of the metal tube 2, respectively open a slot 4, and the left and right slots 4 are located on the cylindrical surface of the metal tube 2. , and the edge of the slot 4 along the opposite direction of the...

Embodiment 1

[0033] The preparation method of the present invention is adopted to obtain a bobbin with a polyurethane film with a thickness of 1mm on the surface, and the double-strand yarn of the full wool 2×8.2tex with a yarn number of 16.4tex is wound on the surface of the bobbin with a tension of 10cN , the winding yarn 6 is naturally stably depressed in the polyurethane film with a rough outer surface and held by its rough surface. There is no dislocation and overlapping of the winding yarn 6 in the whole close-packed winding. The whole friction along the axis of winding yarn 6, winding yarn 6 has no movement; friction along the axis of metal cylinder 2, winding yarn 6 has no obvious movement and tumbling; the friction of the compounded Lissajous curve trajectory of the two, winding yarn 6 has no Noticeable movement and tumbling. The head end of the winding yarn 6 is wound 3 times on the left yarn head nail and the tail end is wound 1 circle on the right yarn head nail, which can eff...

Embodiment 2

[0035]The preparation method of the present invention is adopted to obtain a bobbin with a rubber film with a thickness of 2 mm on the surface, and the cashmere / polyester composite yarn of 7.7 tex is wound on the surface of the bobbin with a tension of 3 cN, and the wound yarn 6 is naturally stably Depressed in and gripped by the roughened rubber membrane on the outer surface. There is no dislocation and overlapping of the winding yarn 6 in the whole close-packed winding. The whole friction along the axis of winding yarn 6, winding yarn 6 has no movement; friction along the axis of metal cylinder 2, winding yarn 6 has no obvious movement and tumbling; the friction of the compounded Lissajous curve trajectory of the two, winding yarn 6 has no Noticeable movement and tumbling. The head end of the winding yarn 6 is wound 2 times on the left yarn head nail and the tail end is wound 2 times on the right yarn head nail, which can effectively fix the winding yarn 6. The acute angle...

Abstract

The invention relates to a yarn drum suitable for fuzzing, pilling and stable grinding of yarns as well as a preparation and a use thereof. The surface of a metal barrel of the yarn drum is coated and bonded with a high polymer film with the thickness of 0.5-3 mm and rough outer surface so as to keep the stability of winding yarns wound on an outer layer and especially guarantee that the winding yarns are stable, move less and even nearly do not move in a yarn grinding process. Due to the existence of the film, the ground winding yarns can be stably pressed in the film and held by the rough surface of the film, the yarns are guaranteed to be not turned or moved in the yarn grinding process, and the fuzzing and pilling results of the yarns are stable. The yarn drum comprises a yarn drum shaft, the metal barrel, the high polymer film, two side embedded grooves and left and right yarn head nails, is a key part of a yarn fuzzing and pilling measurement device, and can be used for yarn grinding sample preparation and measurement of yarn fuzzing and pilling.

Description

technical field [0001] The invention relates to a yarn bobbin suitable for yarn fluffing and pilling and grinding stability, as well as its preparation and application, and belongs to the technical field of testing and evaluating the pilling resistance of textiles. 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 friction performance of yarn and other substances (wood, rubber, metal, leather, fabric) etc. in the course of wearing. Briti...
