Embodiment Construction

[0020] The hygroscopic heating fabric is carried out as follows:

[0021] (a) Use low-formaldehyde resin finishing solution to pad the fabric in the padding tank, and the liquid retention rate is 50% to 70%;

[0022] (b) Dewatering the padded fabric;

[0023] (c) Pre-baking in an oven with a temperature of 100°C, and the pre-baking time is 2 to 5 minutes;

[0024] (d) Dry the fabric in an oven at a temperature of 110-120°C for 5-8 minutes;

[0025] (e) Soak the fabric in the oxygen bleaching and desizing solution for non-alkali oxygen bleaching and desizing, the temperature is 60-70°C, and the soaking time is 30-40 minutes;

[0026] (f) Rinse the fabric after non-alkali oxygen bleaching and desizing;

[0027] (g) dehydration of rinsed fabrics;

[0028] (h) Soak the fabric in caustic soda with a concentration of 20-25% for mercerizing treatment, the temperature is 15-25°C, and the soaking time is 20-40 seconds;

[0029] (i) rinsing the mercerized fabric;

[0030] (j) dehy...

Abstract

The invention belongs to the field of textile technology and particularly relates to an alkali-free oxygen bleaching and desizing and mercerizing finishing process for moisture-absorbing and heating fabric, comprising the following steps: impregnating the fabric by a low-formaldehyde resin finishing liquid in an impregnating tank; dewatering the impregnated fabric; preheating the fabric in a baking oven at 100 DEG C; baking the fabric in the baking oven at 110-120 DEG C; impregnating the fabric in an oxygen-bleaching and desizing liquid to carry out oxygen bleaching and desizing; rinsing the fabric subjected to oxygen bleaching and desizing; dewatering the rinsed fabric; immersing the fabric in caustic soda with content of 20-25% for carrying out mercerization treatment; rinsing the fabric subjected to the mercerization treatment; dewatering the rinsed fabric and subjecting the dewatered fabric to following processing. Compared with the prior art, the finishing process for the fabric additionally adopts the alkali-free treatment step, the mercerizing step so that the mercerized fabric feels more comfortable on one hand and the fabric has the moisture-absorbing and heating performance on the other hand.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an alkali-free oxygen bleaching, desizing, and mercerizing finishing process for hygroscopic and heating fabrics. Background technique [0002] The hygroscopic and heating fibers used in traditional moisture-absorbing and heating fabrics are composed of two special raw materials. The viscose in the yarn is used to absorb the moisture generated during human movement, and a chemical reaction occurs inside the fiber, so the temperature inside the clothes will rise by 2-3°C. Another kind of raw material is special polyester, this polyester is a kind of hollow insulation polyester, its circular cross-section and the flat cross-section of special viscose will form a certain gap inside the fiber, the static air in these gaps will block the insulation from the outside world. The temperature exchange, so as to achieve the role of heat preservation. The capillary phenomenon can quickly ...
