Problems solved by technology

[0002] Cotton clothing has the advantages of moisture absorption, breathability, softness and comfort, but it is also easy to wrinkle and needs to be ironed after washing. In order to avoid the trouble of ironing after washing, it is necessary to perform anti-wrinkle and non-ironing finishing on the fabric
The current non-ironing finishing method has certain disadvantages. One is that the non-ironing finishing agent contains a certain amount of formaldehyde, which will release formaldehyde during the finishing process and wearing process, which will cause greater harm to the human body; the other is that the non-ironing finishing process will Reduce the mechanical properties and hand feel of the fabric, especially if the yarn density is less than 11.7dtex (50 S The pure cotton fabrics above) have low strength in themselves, and the strength of the fabric will further decrease after non-ironing finishing, which will affect the wearing life in severe cases; the third is that the non-ironing function obtained through post-finishing is not durable, and with the use of time The extension of time and the increase of washing times, its non-ironing performance will gradually weaken or even disappear completely

Abstract

The invention discloses a molten binding yarn production process. The molten binding yarn production process includes the following steps: (1) scotching; (2) cotton carding; (3) combing; (4) drawing; (5) roving; (6) spinning; and (7) spooling. The process uses a surface treating agent to perform surface treatment on polyethylene fibers, the phenomena that the polyethylene fibers breaks due to friction, or is molten into small particles or blocks can be reduced further; a process parameter of the molten binding yarn production process is optimized; the process is simple, and is high in operability; the acquired molten binding yarn can be weaved into a fabric, and the garment made of the fabric has a permanent stiff and smooth performance after being ironed, and can avoid ironing after being washed; and the molten binding yarn is especially suitable for producing anti-wrinkle non-ironing shirts.
