Core-spun type low-melting-point hot-melting yarn and tubular fabric and manufacturing method

Abstract

The invention discloses core-spun type low-melting-point hot-melting yarn. The core-spun type low-melting-point hot-melting yarn comprises conventional fiber yarn, the outer surface of each strand of conventional fiber yarn is coated with a layer of low-melting-point hot-melting material layer, the kinetic viscosity of the low-melting-point hot-melting material layers is 1,100-5,000 mpa.s, and the melting point is 80-110 DEG C. The tubular fabric comprises a tubular structure which is formed by weaving several warp and several weft in a staggered mode, wherein the warp is the core-spun type low-melting-point hot-melting yarn, and the weft is conventional yarn; or, the warp is conventional yarn, and the weft is the core-spun type low-melting-point hot-melting yarn; the contact parts of the warp and the weft are heated and melted to be integrally bound. The invention further discloses a preparing method of the tubular fabric. The core-spun type low-melting-point hot-melting yarn has the advantages of being low in melting point and good in binding effect. The tubular fabric has the advantages of being flexible and comfortable, high in anti-piercing capability, and low in production cost. The manufacturing method of the core-spun type low-melting-point hot-melting yarn can greatly lower the difficulty of weaving, the scraps are reduced, the production efficiency is improved, and the dosage of the low-melting-point hot-melting yarn is reduced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a core-spun low-melting hot-melt yarn, a tubular fabric and a manufacturing method. Background technique [0002] In daily life, the lower part of the bust worn by women usually has a wire ring with a fixed bust shape. The wire ring is covered with a tubular fabric. The tubular fabric is used to fix the wire ring position and cushion the wire ring. To the discomfort brought by the body, maintain aesthetics. However, in real life, no matter the human body is wearing or washing, due to irregular external force extrusion factors, the tubular fabric is at risk of being punctured by the wire ring. Therefore, the puncture strength of the tubular fabric is corresponding Added requirements. [0003] Existing bust tubular fabric mainly has two kinds of production methods: [0004] The first production method: adding as many yarns as possible into the entire tubular fabric for weaving,...

AI Technical Summary

Problems solved by technology

The tubular fabric manufactured by this method is only based on the original conventional raw material, and an additional low-melting hot-melt yarn is added, and when two weft yarns of different properties are woven at the same time, the distribution of the hot-melt yarn There is always one side blocked by another conventional yarn, or the contact surface with adjacent yarns is irregular and uncontrollable due to the unavoidable kinks between the yarns during the weaving process. When the hot-melt yarn is melted at a high temperature, it cannot produce adhesion to all adjacent points or surfaces that are in contact with it at a full angle, and the adhesion effect will be greatly reduced. During production, it is easy to cause any yarn breakage or lack of ends in different segments, and when two yarns are in the high-speed weaving process, irregular mutual kinks and two different yarns should be woven to each other. The position in the fabric changes irregularly, which causes uneven distribution of hot-melt yarn, causing serious quality problems

For example: 1. There will be agglomeration in places with a lot of low-melting point materials, and abnormal noise will be found when rubbing against the two ends of the steel ring; Sticking together, separation work must be added in the post-process; 3. Where there are few low-melting point materials, it will be easy to be pierced by the steel traveler
