Problems solved by technology

The limitation of the former is that firstly, the thickness of the pantyhose is too thick and bloated, which weakens the beautification function of the pantyhose; Pilling and poor aesthetics
The limitation of the latter is that the washing and sunlight fastness of the general finishing agent is poor, and the finishing agent will fall off after daily washing for more than 5-10 times, resulting in the unsustainable and durable heating effect

Embodiment 1

[0036] A method for producing a textile material with stretching and heating effect, including the following steps:

[0037] (1) Wrapping: Take 40D stretched heat-generating spandex as inner covering yarn, FDY / DTY70D nylon as outer covering yarn, and wrap it under the conditions of 320T / M twist, 3.2 draft ratio and 90% overfeed rate. Wrapping yarn

[0038] (2) Equilibrium: The obtained wrapped yarn is equilibrated for 5 days under the condition of 20-25°C for knitting;

[0039] (3) Knitting: Under the conditions of 20-25°C and relative humidity of 60%-65%, use a 9mm tongue and 320 needle knitting machine to knit the wrapped yarn after the balance treatment. The plain weave yarn is used during the knitting process. Get braid

[0040] (4) Degreasing: Put the emulsifier Tuna EWN (additional amount of 2g / L) in water at 40°C, stir evenly, put the braid in water, then heat up to 90°C for 30 minutes and take out the braid Wash the braid with cold water to remove residual oil stains;

Abstract

The invention relates to the field of textiles, in particular to a textile material with a tensile heating effect as well as a production method and an application. The textile material takes tensile heating polyurethane fibers as inner wrapping silk and polyamide as outer wrapping silk. The production method comprises the steps of firstly performing wrapping to obtain wrapped yarns; secondly performing knitting by adopting a 7-9mm needle latch and 280-360 stitches, and dyeing a knitted fabric by using a weak acidic dyeing agent; and finally performing shaping treatment at 70-90 DEG C under the shaping pressure of 0-2pa for 20-40 seconds to obtain the textile material. According to the textile material as well as the production method and the application, production parameters in each step are optimized in a production process, so that the best production conditions are obtained; the textile material produced under the conditions has the best tensile heating effect; and a heat generation and retention effect can be achieved through stretching during wearing when a finished textile is produced.

Description

Technical field [0001] The present invention relates to the technical field of textiles, in particular to a textile material with stretching and heating function, and a production method and application. Background technique [0002] The development of functional textiles is an important means to upgrade the quality of textile products, increase the added value of products and change the mode of economic growth. The improvement of people's wearing standards and the development of science and technology will surely promote the development of functional textiles. Functional socks refer to products that have other special functions besides covering and beautifying functions of socks in the traditional sense. [0003] In recent years, domestic and foreign socks manufacturers have launched heat-generating warm socks, mainly focusing on choosing fibers with higher denier or count to achieve warmth, such as choosing 300D nylon filament, adding cotton fiber, acrylic fiber, wool fiber, cash...
