Problems solved by technology

[0002] In the prior art, if one side is made of single-face fleece structure and the other is coral fleece structure, it can only be solved by compounding two fabrics. Although this solves the style problem, the formaldehyde content is caused by compounding with glue. Problems such as exceeding the standard, poor peeling fastness and washability, relatively hard hand feeling, and weight gain, etc.

Embodiment 1

[0025] (1) Use 75D polyester DTY yarn as the loop of one side of the fleece, use 100D polyester DTY yarn treated at 120°C as the loop of the coral fleece side, and use 50D polyester FDY yarn as the bottom yarn, through the loom structure, coil selected rough cloth;

[0026] (2) Through the treatment of alkali reduction, the composition of alkali reduction is to add caustic soda 2.5g / L, and to oil spirit 1g / L; heat up to 120°C, keep moisture for 50 minutes, then cool down to 70°C to drain, and then enter Add glacial acetic acid 0.5g / L to the specified water level and raise the temperature to 60°C for 10 minutes to drain the liquid, then enter the water and raise the temperature to 40°C for 10 minutes to wash;

[0027] The single-face suede terry and the coral suede terry are respectively processed to obtain composite polyester knitted fabrics.

[0028] Single-sided suede loops are used for napping, combing, shearing, and shaking. The specific process is as follows:

Embodiment 2

[0040] (1) Use 300D polyester DTY yarn as the loop of one side of the fleece, use 300D polyester DTY yarn treated at 130°C as the loop of the coral fleece side, and use 100D polyester FDY yarn as the bottom yarn, through the loom structure, coil selected rough cloth;

[0041] (2) Through the treatment of alkali reduction, the composition of alkali reduction is to add caustic soda 5g / L, deoiling spirit 3g / L; heat up to 130°C, keep moisture for 103 minutes, then cool down to 80°C to discharge liquid, and then enter water Add glacial acetic acid 1.5g / L to the specified water level and raise the temperature to 60°C for 10 minutes to drain the liquid, then enter the water and raise the temperature to 40°C for 20 minutes to wash;

Abstract

The invention relates to a preparation method of a composite terylene knitted fabric, which comprises the following steps of: (1) using DTY (Draw Textured Yarn) yarns as terry of a single-sided velvet surface, using DTY yarns which are processed at a temperature of 120 to 130 DEG C as terry of a coral velvet surface, using FDY (Fully Drawn Yarn) yarns as bottom yarns and selecting blank cloth by a weaving machine structure and a coil; and (2) by processing of alkali weight reduction, respectively processing the terry of the single-sided velvet surface and the terry of the coral velvet surface to obtain the composite terylene knitted fabric. The preparation method has simple process and low cost and is environmental-friendly; two different napped style effects are formed by the variation of a tissues structure and different shrinkage principles of polyester yarns; and the prepared composite terylene knitted fabric has soft hand feeling, light gram weight and wide application prospect.

Description

technical field [0001] The invention belongs to the field of polyester fabric preparation, in particular to a preparation method of composite polyester knitted fabric. Background technique [0002] In the prior art, if one side is made of single-face fleece structure and the other is coral fleece structure, it can only be solved by compounding two fabrics. Although this solves the style problem, the formaldehyde content is caused by compounding with glue. Problems such as exceeding the standard, poor peeling fastness and washability, relatively hard hand feeling, and weight increase. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of composite polyester knitted fabric, which forms two different napping style effects through the change of tissue structure and the principle of different shrinkage of polyester filaments, with soft hand feeling and light weight . [0004] A kind of preparation ...
