Embodiment 1

[0023] The preparation of a memory type high-grade elastic knitted fabric comprises the following steps:

[0024] First, weaving the fabric, using water jet loom or air jet loom to weave double-sided structure memory type high-grade elastic knitted fabric with interlaced corrugated three-dimensional structure on one side and flat and smooth linear straight strip on the other side; the warp yarn is PTT elastic memory length Silk, the weft yarn is PTT / PET composite blended yarn; by mass percentage, the consumption of PTT elastic memory filament in the double-sided structure fabric is 50%, and the consumption of the PTT / PET composite blended yarn is 50%.

[0025] Secondly, wet heat treatment, immersing the memory type high-grade elastic knitted fabric in a 95°C water bath containing penetrating agent SP-2, and performing wet treatment for 30 minutes; the content of the penetrating agent SP-2 in the water bath is 0.5-1g / L, The water bath also includes 2-3g / L sodium hydroxide, 3g / ...

Embodiment 2

[0031] The preparation of a memory type high-grade elastic knitted fabric comprises the following steps:

[0032] First, weaving the fabric, using water jet loom or air jet loom to weave double-sided structure memory type high-grade elastic knitted fabric with interlaced corrugated three-dimensional structure on one side and flat and smooth linear straight strip on the other side; the warp yarn is PTT elastic memory length Silk, the weft yarn is a PTT / PET composite blended yarn; by mass percentage, the PTT elastic memory filament consumption in the double-sided structure fabric is 55%, and the PTT / PET composite blended yarn consumption is 45%.

[0033] Secondly, wet heat treatment, immersing the memory type high-grade elastic knitted fabric in a 95°C water bath containing penetrating agent SP-2, and performing wet treatment for 30 minutes; the content of the penetrating agent SP-2 in the water bath is 0.5-1g / L, The water bath also includes 2-3g / L sodium hydroxide, 3g / L hydrog...

Embodiment 3

[0039] The preparation of a memory type high-grade elastic knitted fabric comprises the following steps:

[0040] First, weaving the fabric, using water jet loom or air jet loom to weave double-sided structure memory type high-grade elastic knitted fabric with interlaced corrugated three-dimensional structure on one side and flat and smooth linear straight strip on the other side; the warp yarn is PTT elastic memory length Silk, the weft yarn is a PTT / PET composite blended yarn; by mass percentage, the PTT elastic memory filament consumption in the double-sided structure fabric is 60%, and the consumption of the PTT / PET composite blended yarn is 40%.

[0041] Secondly, wet heat treatment, immerse the memory type high-grade elastic knitted fabric in a 95°C water bath containing penetrant SP-2, and perform wet treatment for 30 minutes; the content of the penetrant SP-2 in the water bath is 1g / L, and the The water bath also included 2 g / L sodium hydroxide, 3 g / L hydrogen peroxid...

Abstract

The invention relates to a memory high-grade elastic knitted fabric and a preparation method thereof. A fabric in double-face structure interwoven by warp and weft is dyed and fished to obtain the knitted fabric; one face of the double-face structure is an interlaced wave stereoscopic structure and the other face is a flat smooth linear stripe structure; the warp refers to the PTT elastic memory filament and the weft refers to the PTT / PET compound blended yarn. The warp which refers to the PTT elastic memory filament and the weft which refers to the PTT / PET compound blended yarn are blended toobtain a double-component fiber material with special elasticity; as the polyester fibers have different shrinkage rates, the fiber material can generate permanent stereoscopic crimp and accordinglycan have excellent elasticity; the fabric shrinks mildly through wet processing with set temperature so that internal stress of the fabric is reduced, and further, the problem of uneven dyeing due toshrinkage difference of the fabric when the PTT elastic memory filament withstands a high temperature is avoided through suitable pre-heating sizing and appropriate dyeing process.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a memory-type high-grade elastic knitted fabric and a preparation method thereof. Background technique [0002] With the continuous development of the economy and the gradual improvement of living standards, as well as the development of knitted garments towards high-grade and multi-functional, people's requirements for clothing have also increased accordingly. Memory-type high-grade elastic knitted fabrics are soft, smooth, smooth and bright, Moisture absorption and moisture conduction, anti-wrinkle and non-ironing, easy to care, are welcomed by people. But because the existing memory fabric has some deficiencies in the production process, the produced memory fabric has the problems of hard hand feeling and insufficient comfort. [0003] PTT fiber is a new type of polyester textile fiber material with good elasticity, softness and dyeing properties. It is the main material for weaving me...
