Embodiment 1

[0053] The method for controlling the shrinkage of the fabric provided by the present embodiment comprises the following steps:

[0054] Step S1: Sampling and marking the fabric, drawing a 50×50 frame, taking the fabric in the frame as a sample, and performing a washing test on the sample; the washing test includes: placing the sample in water and soaking it for 5 minutes to allow the fabric to absorb enough water. Then dehydrate, dry at 75°C, and then air-cool to 10°C, the shrinkage rate of the fabric is measured to be 4%;

[0055] Step S2: Measure the width of the fabric before washing M=136cm, calculate according to n=M-M×v%, get n to be 130.5cm, determine the width of the marking frame of the fabric N=130cm, and arrange the marking frame according to the width of 130cm , the net length of the marker is L=438cm;

[0056] According to Y=L×(1+v%×1.2), determine the length Y of the row marker, and calculate Y=459cm;

[0057] Step S3: Check the size and quality of the fabrics...

Embodiment 2

[0062] The method for controlling the shrinkage of the fabric provided by the present embodiment comprises the following steps:

[0063] Step S1: Sampling and marking the fabric, drawing a 50×50 frame, taking the fabric in the frame as a sample, and performing a washing test on the sample. The washing test includes: placing the sample in water and soaking it for 10 minutes to allow the fabric to absorb enough water. Then dehydrate, dry at 85°C, and then air-cool to 25°C, the shrinkage rate of the fabric is measured to be 3%;

[0064] Step S2: Measure the fabric width M=100cm before washing, calculate according to n=M-M×v%, and get n to be 97cm, confirm that the width of the marking frame of the fabric is N=97cm; arrange the marking frame according to the width of 97cm, The net length of the marker is L=310cm;

[0065] According to Y=L×(1+v%×1.5), determine the length Y of the row marker, and calculate Y=324cm;

[0066] Step S3: Check the size and quality of the fabrics, then...

Embodiment 3

[0072] The method for controlling the shrinkage of the fabric provided by the present embodiment comprises the following steps:

[0073] Step S1: Sampling and marking the fabric, drawing a frame of 50×50, taking the fabric in the frame as a sample, and performing a washing test on the sample. The washing test includes: placing the sample in water and soaking it for 8 minutes to allow the fabric to absorb enough water. Then dehydrate, dry at 80°C, and then air-cool to 15°C, the shrinkage rate of the fabric is measured to be 4%;

[0074] Step S2: Measure the width of the fabric before washing M=120cm, calculate according to n=M-M×v%, get n to be 115.2cm, determine the width of the marking frame of the fabric N=115cm; arrange the marking frame according to the width of 115cm , the net length of the marker is L=385cm;

[0075] According to Y=L×(1+v%×1.4), determine the length Y of the row marker, and calculate Y=406.5cm;

[0076] Step S3: Check the size and quality of the fabric...

Abstract

The invention provides a control method of shrinkage rate of fabrics and relates to the technical field of processing of fabrics. The control method of shrinkage rate of fabrics comprises the following steps: initially checking a fabric and testing shrinkage rate v% of the fabric; measuring breadth M of the fabric before washing, calculating according to a formula: n=M-M*v%, and determining breadth N of a marker laying frame; setting net length of a marker frame as L and determining the length Y of the marker laying frame of the fabric; checking the fabric; flatly unfolding the fabric, determining the length X of the unfolded fabric before washing on a cutting bed, then cutting and breaking the fabric, and marking the cut fabric; washing and soaking the fabric for 10-15 minutes, then dewatering, drying at 75-85 DEG C, and cooling to 10-25 DEG C in the air; flatly unfolding the fabric, determining the length of the washed and unfolded fabric on the cutting bed and ensuring that the length of the washed and unfolded fabric is greater than or equal to the net length L of the marker frame and the breadth of the washed fabric is greater than or equal to the breadth N of the marker laying frame.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a method for controlling the shrinkage rate of fabrics. Background technique [0002] In terms of garment manufacturing, whether the shrinkage rate of fabrics is stable is very important, which directly affects the size of garment products and the wearing effect of consumers, while the size of casual washed garments is extremely difficult to control, especially elastic fabrics and knitted fabrics. The biggest test and challenge of technology. The inaccurate size of garment products generally includes the following reasons: [0003] 1. The shrinkage rate of the fabric is unstable, and the shrinkage rate of different pieces of fabric varies greatly, which is 8-9%, or even more than 10%, exceeding the national standard; [0004] 2. The shrinkage rate of the same piece of fabric is unstable, and the shrinkage rate varies greatly, and the fabric is tight in the middle and ...
