Polyester/spandex sandwich antibacterial fabric and dyeing and finishing method thereof

Abstract

The invention discloses a polyester / spandex sandwich antibacterial fabric and a dyeing and finishing method thereof. The polyester / spandex sandwich antibacterial fabric is formed by weaving an upper fabric layer, a lower fabric layer and a connecting layer through a double-side weft knitting machine, and the connecting layer is made with 20D to 70D polyester MOLO yarns, the upper fabric layer is made by interweaving 30D to 50D common polyester yarns and 20D spandex, and the lower fabric layer is made by interweaving 30D to 50D profiled-section polyester yarns, 30D to 50D copper fiber antibacterial yarns and 20D spandex. The dyeing and finishing method comprises the steps of presetting, dyeing, carrying out finishing setting and carrying out direct treatment through a shrinking mixer beforepresetting; a deoiling formula includes 2-6 g / L of an efficient degreaser, 1-3 g / L of caustic soda and 1-3 g / L of a spandex degreaser. The polyester / spandex sandwich antibacterial fabric according tothe invention has the functions of warmth retention, quick drying and antibiosis, is good in resilience, feels thick and comfortable, can effectively avoid creases in the dyeing and finishing process, and has excellent fastnesses.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a polyester / ammonia sandwich antibacterial fabric and a dyeing and finishing method thereof. Background technique [0002] The sandwich fabric consists of upper, middle and lower sides. The surface is usually designed with mesh, the middle layer is MOLO yarn connecting the surface and the bottom surface, and the bottom surface is usually a densely woven flat surface, commonly known as "sandwich". There is a layer of dense net under the fabric, so that the net on the surface will not be deformed too much, and the fastness and color of the fabric are enhanced. The mesh effect makes the fabric more modern and sporty mesh effect. It is made of polymer synthetic fiber and woven by precision machine at one time. It is durable and belongs to the high-quality warp knitted fabric. [0003] However, this common warp-knitted sandwich fabric has a large sur...

AI Technical Summary

Problems solved by technology

[0003] However, this kind of common warp-knitted sandwich fabric has large surface mesh, poor fluffy feeling, and unsatisfactory resilience, and the surface is easy to collect dust, and the front and back are often reversed, so it is not suitable for clothing fabrics.

[0004] In addition, during the production process of the existing sandwich fabrics, the MOLO yarn in the middle often has irregular lodging, which affects the fluffy feel of the fabric, and the lodging of the MOLO yarn forms a shadow on the cloth surface, which affects the quality of the cloth surface; while for polyester / ammonia Sandwich fabrics also have the problem that spandex is easy to fuse
