Problems solved by technology

Later in the 1999 document "E.K.Boylston. Microscopical Evaluation of Yarns. Textile Chemistand Colorist. 1999, 31 (2): 20-22" reported that E.K.Boylston and others applied different proportions of methacrylate system resins to the yarn. Embedding has also achieved good results, but this fiber embedding method involves pre-polymerization of monomers and further UV-induced reactions, etc., which is relatively complicated.

Embodiment 1～13

[0063] The fibers are:

[0064] Loose cotton fiber, ramie fiber, kapok fiber, ordinary viscose fiber, wool fiber, nylon trilobal fiber, polyester quatrefoil fiber, polyester trilobal fiber, polyester oval fiber, polyester polygonal fiber, polyester single hollow fiber, Acrylic straight fiber, acrylic blended fiber;

[0065] First, use an iron comb to comb each of the above-mentioned fibers neatly, and then tie the two ends of the fibers with yarn to ensure that the fibers are in a naturally stretched and straight state.

[0066] The above-mentioned fibers were respectively impregnated in the following embedding media:

[0067] Methyl methacrylate: butyl methacrylate: polymethyl methacrylate = 3: 2.6: 0.9, and in the bottle of BPO with 1% total monomer weight, vacuum the air bubbles in the fibers until no air bubbles appear until. Pour the embedding medium in the bottle into a polypropylene tube, seal both ends of the tube with stoppers, slightly tighten the yarns binding th...

Embodiment 14～16

[0072] Fibers used:

[0073] Loose cotton fiber, ramie fiber, acrylic fiber blended fiber, adopt the same detection method of embodiment 1.

[0074] First, use an iron comb to comb each of the above-mentioned fibers neatly, and then tie the two ends of the fibers with yarn to ensure that the fibers are in a naturally stretched and straight state.

[0075] The above-mentioned fibers were respectively impregnated in the following embedding media:

[0076] Styrene: polystyrene = 5 ~ 6: 1 = 5.5: 1, and in the bottle of BPO with 1% of the total weight of the monomer, vacuum the air bubbles in the fibers until no air bubbles appear. Pour the embedding medium in the bottle into a polypropylene tube, seal both ends of the tube with stoppers, slightly tighten the yarn that binds the ends of the fiber, keep the tube vertical, and place it at 100°C for about 2.5 hours of polymerization reaction. Prepare embeddings. For fiber cross-sectional images, see Figure 27 , 29 and 31.

[0078] The fiber that adopts: loose cotton fiber, ramie fiber, acrylic fiber blended fiber; Adopt the same detection method of embodiment 1.

[0079] First, use an iron comb to comb each of the above-mentioned fibers neatly, and then tie the two ends of the fibers with yarn to ensure that the fibers are in a naturally stretched and straight state.

[0080] The above-mentioned fibers were respectively impregnated in the following embedding media:

[0081] Vinyl acetate: polyvinyl acetate = 3: 1.8, and a bottle of BPO with 1% of the total weight of the monomers, vacuumed to remove air bubbles in the fibers until no air bubbles appeared. Pour the embedding medium in the bottle into a polypropylene tube. After the two ends of the tube are sealed with stoppers, slightly tighten the yarn that binds the ends of the fiber, and place it at a temperature of 83°C for about 1.5 hours of polymerization reaction, and then raise the temperature to Polymerize at 120°C for 1.5h to prepare the...

Abstract

The invention relates to a method for using resin to pack fiber, which comprises: dipping fiber into packing medium, to be polymerized at 80-120Deg. C for 2-4 hours, to obtain the fiber packing body as polymethacrylate packing system, polystyrene packing system or polyvinyl acetate packing system, wherein the invention adds polymer into monomer to adjust the viscosity of system, to avoid the pre-polymerizing reaction of monomer; in addition, it directly uses BPO to initialize monomer to process free group combined polymerization for 2-3 hours, to reach the packing demands, with simple process and high packing speed. And the invention can packing variable fibers, with clear fiber edge, better disperse degree and improved image quality.

Description

technical field [0001] The invention relates to a method for embedding fiber with resin, in particular to a method for quickly embedding textile fiber resin based on computer image recognition. Background technique [0002] The cross-section of each textile fiber has certain characteristic shapes. For example, the cross-section of natural cotton fiber is irregular waist-circle, and there is a dry cavity in the center of the cross-section; the cross-section of a single silkworm cocoon without sericin is irregular oval, and is covered by two silk fibroin. The cross-section of a single silk fibroin after removing sericin is irregular triangle; while the cross-section of tussah cocoon silk is flat and oblong, and the triangle of sericin is also flat, like horns, with tiny pores inside; different types of hemp The cross-sectional shapes of the fibers are also different. Most of the ramie is waist-round, with a middle cavity, and the cell wall has cracks; the cross-section of fla...
