Embodiment 1

[0021] Embodiment 1: a kind of preparation method of biodegradable cool feeling fabric, such as figure 1 shown, including the following steps:

[0022] S1. Raw material selection:

[0023] The base material is made of polyester chips, the biodegradable additive is made of EcoPure PET (G2), and the cooling agent is made of jade powder.

[0024] S2. Dilute granulation of biodegradable additives:

[0025] The biodegradable additive and the polyester chip are mixed evenly in the drum according to the mass ratio of 1:5, and then granulated by a twin-screw granulator to obtain the diluted biodegradable additive masterbatch.

[0026] S3, the preparation of biodegradable cooling fiber, comprising the following steps:

[0027] The first process step: the base material, the diluted biodegradable additive masterbatch and the cooling additive are mixed uniformly in a drum by vacuum heating and drying at a mass ratio of 90:5:5.

[0028] The second step: the dried mixture is melted and ...

Embodiment 2

[0044] Embodiment 2: a kind of preparation method of biodegradable cool feeling fabric, and the step different from embodiment 1 is:

[0045] S5. Weaving:

[0046] Equipment: Meyer West single-sided machine with 34 inches and 28G stitches.

[0047] Fabric Weave: Single Piqué.

[0048] Yarn length: 26.5cm / 100N.

[0049] S6, dyeing, comprises the following steps:

[0050] 1. Pre-treatment process: add degreasing agent and refining agent at room temperature, raise the temperature to 98°C at a rate of 2°C / min, keep warm for 30 minutes, cool down to 75°C at a rate of 2°C / min, drain water, and then wash with water for 2 times, washed with glacial acetic acid once;

[0051]2. Dyeing process: Add leveling agent and glacial acetic acid at 40°C, adjust the pH value to 3.7-4.2, add dye, heat up to 90°C at a rate of 2-3°C / min, and then increase the temperature at a rate of 1°C / min Keep warm at 130°C for 35 minutes, then cool down to 70°C at a rate of 2°C / min to take samples.

Abstract

The invention discloses a preparation method of a biodegradable cool fabric, and belongs to the technical field of weft knitted fabric preparation. According to the key points of the technical scheme, the method comprises the following steps of S1, selection of raw materials including a base material, a biodegradable additive and a cool additive; S2, dilution and granulation of the biodegradable additive; S3, preparation of biodegradable cool fibers; S4, spinning; S5, weaving; S6, dyeing; S7, dewatering; and S8, setting. According to the preparation method of the biodegradable cool fabric, the biodegradable cool fabric has better biodegradability and wearing comfort.

Description

technical field [0001] The invention relates to the technical field of preparation of knitted weft-knitted fabrics, in particular to a preparation method of a biodegradable cool fabric. Background technique [0002] The biodegradable additive is a mixed substance that can help polyester fibers increase the biodegradation rate. It is generally in a solid state, and polyester chips are generally in a solid state. During the preparation of biodegradable polyester fibers, when the amount of biodegradable masterbatch added is particularly low (such as 1%), uneven distribution of biodegradable additives in polyester fiber chips is likely to occur. When the amount of biodegradable additives contained in some polyester fiber regions is high, the degradation rate of polyester fibers is fast, and when the biodegradable additives contained in some polyester fiber regions are relatively small, the degradation rate is slow, thus This results in slower biodegradation of fabrics made from...
