Problems solved by technology
[0002] Polyester industrial filaments can be divided into ultra-high strength, high-strength, low-shrinkage, ultra-low-shrinkage and high-modulus low-shrinkage types according to performance. Different types use different oil agents. And the production of cords has a great influence, which will directly affect the processing performance and product quality, but the existing raw silk oil content test principle and process complexity are relatively complicated, and there is a large deviation in the measured oil content, so , it is particularly important to solve such problems

Embodiment Construction
[0015] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.
[0016] This embodiment provides a method for detecting the oil content of raw silk, including the following detection steps:
[0017] Step 1: Take a small part of the sample wire one by one, cut it into a short wire with a length of about 50mm, and after fully mixing, weigh four samples of 5g and weigh to an accuracy of 0.0001g;
[0018] Step 2: The woven bag is cleaned and dried to a constant weight, and the weighing bottle is dried to a constant weight;
[0019] Step 3: Put two parts of the sample into woven bags and weigh them, subtract the weight of the bag itself, and obtain the mass G1 of each sample before washing;
[0020] Step 4: Inject the washing solution into each washin...

The invention discloses a detection method of oil content of raw filaments. The method includes the steps of: a) fetching a small part one-by-one from sample filaments, and cutting the filament into short filaments being about 50 mm long, fully mixing the short filaments, and weighing four parts of samples by weight of 5 g; b) washing woven bags, and drying the woven bags to constant weight and drying weighing bottles to constant weight; c) weighing two parts of the samples respectively in the woven bags to obtain the mass of the samples G1 before washing; d) respectively injecting the washingliquid into washing containers, sealing the woven bags in which the samples are placed, and placing the woven bags in the washing containers, capping the washing containers, and performing ultrasonicvibration in an ultrasonic cleaning device; e) washing the woven bags in which the samples are placed with distilled water for more than three times, wherein the woven bags are wringed, in a pressingmanner, to dry after each washing operation; f) respectively placing the two dehydrated woven bags, in which the samples are placed, and another two non-washed samples into the weighing bottles withconstant weight, drying the samples to constant weight, placing the bottles in a dryer, and cooling the samples at room temperature, and weighing the bottles; g) calculating the oil content of raw filaments.
Description
technical field [0001] The invention relates to the technical field of industrial cloth production, in particular to a method for detecting the oil content of raw silk. Background technique [0002] Polyester industrial filaments can be divided into ultra-high strength, high-strength, low-shrinkage, ultra-low-shrinkage and high-modulus low-shrinkage types according to performance. Different types use different oil agents. And the production of cords has a great influence, which will directly affect the processing performance and product quality, but the existing raw silk oil content test principle and process complexity are relatively complicated, and there is a large deviation in the measured oil content, so , it is particularly important to solve such problems. Contents of the invention [0003] The invention provides a method for detecting the oil content of raw silk, and the specific scheme is as follows: [0004] A method for detecting the oil content of raw silk, c...
