Problems solved by technology

However, because the shrinkage rate of POY / FDY different shrinkage mixed fiber yarn is particularly large and generally exceeds 50%, when tested according to the normal national standard polyester filament dyeing uniformity test method, the sock sample shrinks seriously in boiling water at 100°C, which makes it impossible to judge normally.

Embodiment 1

[0018] In conjunction with Fig. 1, the present invention is made a specific explanation:

[0019] The first step of hosiery knitting process: According to the requirements of the national standard polyester filament dyeing uniformity inspection method, different shrinkage polyester filaments are used for hosiery knitting, and three socks tubes formed by three kinds of different shrinkage polyester filaments are knitted together to form a For the sock sample 1, weave a 5cm-long isolation pattern 2 on both sides of the sock sample 1.

[0020] The second step is to wear the shaped frame process: insert the special shaped frame 3 into the formed sock sample 1, the special shaped frame 3 is in the shape of a strip, its length is slightly longer than that of the sock sample 1, and its width is about 0.5 cm wider than the sock sample.

[0021] The third step is to fix the sock sample process: fix the sock sample 1 worn on the special shaping frame 3, that is, fix the isolated weaving...

Abstract

The invention aims to provide a different-shrinkage polyester filament yarn dyeing uniformity test method. The method includes the following processes that (1) sock weaving is conducted on different-shrinkage polyester filament yarn according to requirements in the national standard polyester filament yarn dyeing uniformity test method to enable multiple sock legs formed by the various kinds of different-shrinkage polyester filament yarn to be weaved together so as to form a sock sample; (2) a special forming frame is inserted into the formed sock sample, the special forming frame is of a strip shape, the length of the special forming frame is equal to or larger than that of the sock sample, and the width of the special forming frame is matched with that of the sock sample; (3) the sock sample on the special forming frame is fixed through a clamping object; (4) the fixed sock sample is put into a thermostat water bath to be shaped; (5) dyeing and color judgment are conducted on the sock sample processed through heat shaping according to the national standard polyester filament yarn dyeing uniformity test method. The different-shrinkage polyester filament yarn dyeing uniformity test method has the advantages that by means of the method, the dyeing uniformity of the different-shrinkage polyester filament yarn can be tested according to the national standard normally in the different-shrinkage polyester filament yarn dyeing uniformity test process.

Description

technical field [0001] The invention relates to a method for testing the dyeing uniformity of polyester filaments, in particular to a method for testing the dyeing uniformity of different shrinkage polyester filaments. Background technique [0002] When inspecting the dyeing uniformity of polyester filaments, the national standard GB / T6508-2001 discloses the hosiery dyeing method, that is, the polyester filaments to be inspected are woven into stocking tubes, and the dyeing uniformity is judged. However, in the actual production process, there will be some polyester filaments with different shrinkage, which cannot be tested by the method stipulated in the national standard. For example, polyester POY / FDY different shrinkage mixed fiber yarn is simply polyester pre-oriented yarn (PET-POY) and Polyester drawn yarn (PET-FDY) is a filament with different shrinkage rates formed by processing such as merging and networking. The fabric made of this fiber not only has the character...
