Problems solved by technology

In this way, not only the cycle is long, but also the development cost remains high, which wastes a lot of manpower and material resources
Moreover, the yarn sales requirements of yarn manufacturers are sold in batches, just like a batch of yarn is sold by 476 grains (5-18 kg / grain). waste

Embodiment 1

[0015] A yarn matching method for polyester-nylon interwoven hollow fabrics, which uses a dry-drying method to test the dry heat shrinkage of nylon fiber yarn and polyester fiber yarn respectively, takes a fixed-length sample and heats it to 175°C, and measures the length of each sample after baking for 30 minutes , and calculate the dry heat shrinkage of each sample, the calculation formula of dry heat shrinkage is (original length before dry heat - length after dry heat) / original length before dry heat × 100%, choose dry heat shrinkage ≤ 4.5% and close to High-quality nylon yarn and polyester yarn are used as raw material yarns for fabrics.

[0016] The equipment used is as follows

Embodiment 2

[0033] It is basically the same as Example 1, the difference is that the dry heat wet recovery rate of nylon fiber filaments is also measured and calculated, and the fixed-length samples are heated to 175°C, and the length of each sample is measured after baking for 30 minutes, and then the dry heat After dipping the sample in water, measure the length after dipping in water, and calculate the recovery rate of dry heat dipping in water. The formula for calculating the recovery rate of dry heat dipping in water is (length after dipping in water-length after dry heat) / length after dry heat×100 %, choose nylon yarn with dry heat wet recovery rate ≤ 3.5%. Specifically, select the average value of 6 1000 mm nylon fiber filaments for testing. Put it into a dry heat oven set at 175 degrees, dry for 30 minutes, take out the nylon fiber filament, measure its length, if it is 955 mm, the dry heat shrinkage rate is 4.5%, and the nylon fiber with a length of 955 mm After sticking to wate...

Embodiment 3

[0040]It is basically the same as Example 1, the difference is that the dry heat strength loss rate of all samples is also detected and calculated, and the steps include: (1) sampling the chemical fiber to be tested, carrying out the tensile performance test according to the GB / T14344 standard, and detecting at normal temperature Obtain the breaking strength; (2) Take an equal amount of sample, put it into an electric blast drying oven, heat it to 175°C, and bake it for 30 minutes; (3) Take out the sample after baking, and measure the strength after dry heat; (4 ) Calculate the loss rate of dry heat strength and select yarns with a loss rate of dry heat strength≤30%, the formula for calculating the loss rate of dry heat strength is (breaking strength-strength after dry heat) / breaking strength×100%.

[0041] Detecting result is the same as embodiment one, and yarn matching is as follows:

[0042] The dry heat strength loss rate of No. 1 sample and No. 4 sample were 62.1% and 27...

Abstract

The invention provides a method for arranging yarns of polyester-nylon interwoven hollow fabrics. The dry-heat shrinkage rates of nylon fiber filaments and polyester fiber filaments are respectively tested by dry-drying method, and a fixed-length sample is taken and heated to a certain temperature between 170-180°C. , measure the length of each sample after baking for 25-35 minutes, and calculate the dry heat shrinkage rate of each sample. The calculation formula of the dry heat shrinkage rate is (original length before dry heat-length after dry heat) / original length before dry heat×100 %, select nylon yarn and polyester yarn with a dry heat shrinkage rate of ≤4.5% and close to it as the raw material yarn of the fabric, and also detect the recovery rate of the dry heat and water of the nylon fiber filament. The mesh fabric is not easy to wrinkle after high-temperature dyeing and finishing, the fabric surface has high flatness, and the loss of physical properties is small, which meets the physical property requirements of shoe uppers, and reduces development costs and shortens the development cycle.

Description

technical field [0001] The invention relates to the technical field of shoe upper manufacturing, in particular to a method for arranging yarns of polyester-nylon interwoven hollow fabrics. Background technique [0002] In the warp knitted mesh industry, especially the mesh composed of two or more yarns of different materials (such as nylon and polyester two-color mesh), the gray cloth and the finished mesh after printing and dyeing often have a large change in the style of the cloth surface, and the mesh product Wrinkles do not conform to the ideal state of the design, and the physical properties of the product cannot meet the physical property standards applied to shoe uppers. Moreover, the physical properties of warp-knitted mesh shoe materials of the same fabric are sometimes high and sometimes low. After the dyeing and finishing process, the physical properties of each vat are different. For a long time, the warp-knitted fabrics of the same variety, the same machine, an...
