Problems solved by technology

[0003] At present, gold and silver threads are widely used in lace fabrics to improve the grade of fabrics. However, due to the shortcomings of gold and silver threads that are not resistant to acid and alkali, high temperature and wear, there are many problems in dyeing and finishing. Difficult, especially the dyeing process of gold, silver and rayon, nylon blended lace, if the conventional process is used, the gold and silver will be seriously faded, and the fabric will completely lose the luster of the sequins

Embodiment 1

[0018] The specific implementation steps are as follows:

[0019] a) Fabric weaving, the raw materials selected for lace fabric include: 140D rayon, silver thread, 36D nylon filament, 196D spandex; the lace fabric is woven by blending process, and the blending ratio is: rayon 3%, 1.5% gold flakes, 82% nylon filaments, 13.5% spandex.

[0020] b) Pre-treatment, during the weaving process of lace fabrics, some unevenly distributed tension and about 10% of oil will remain in the fabric, so pre-treatment is required to remove them. Pre-treatment uses 2% neutral oil-removing refining agent and 2g / L soda ash, bath ratio 1:15, wash with hot water at 75°C for 40 minutes, and at the same time properly adjust the speed of the cloth lifting roller and nozzle pressure in the dyeing vat to reduce the friction of the gray cloth in the dyeing vat.

[0021] c) Pre-shaping, the lace fabrics are pre-treated before pre-shaping. The pre-shaping temperature is 185°C, the shaping speed is 30m / min, ...

Embodiment 2

[0026] The specific implementation steps are as follows:

[0027] a) Fabric weaving, raw materials for lace fabric include: 140D rayon, silver filament, 36D nylon filament, 196D spandex; the lace fabric is woven by blending process, and the blending ratio is: rayon 5%, Gold flakes are 2.2%, nylon filaments are 84%, and spandex filaments are 8.8%.

[0028] b) Pre-treatment, during the weaving process of lace fabrics, some unevenly distributed tension and about 10% of oil will remain in the fabric, so pre-treatment is required to remove them. Pre-treatment uses 2% neutral oil-removing refining agent and 2g / L soda ash, bath ratio 1:20, wash with hot water at 80°C for 30 minutes, and at the same time properly adjust the speed of the cloth lifting roller and nozzle pressure in the dyeing vat to reduce the friction of the gray cloth in the dyeing vat.

[0029] c) Pre-shaping, lace fabrics are pre-treated before pre-shaping. The pre-shaping temperature is 190°C, the shaping speed is...

Abstract

The invention provides a dyeing and finishing process for a lace fabric. The dyeing and finishing process comprises the following steps: a) weaving of a fabric; b) pre-processing; c) pre-shaping; d) dyeing treatment; e) dye fixation and mellowing; and f) post-processing. The dyeing and finishing process revealed in the invention has the following advantages: process procedures are reasonably arranged; implementation of the process is scientific and simple; the prepared lace fabric can permanently keep bright sheen, is washable and durable, wear-resistant and non-fading, and has a high market value compared to products of a same kind.

Description

technical field [0001] The invention relates to a fabric processing method, in particular to a dyeing and finishing process of lace fabric, which belongs to the technical field of textiles. Background technique [0002] With the improvement of people's living standards and cultural tastes, new changes have taken place in the concept of dressing, from the traditional focus on durability, cold protection and warmth to today's advocating fashion freedom, sports and leisure, emphasizing environmental protection, anti-pollution, and health care. , Comfortable fit, casual and natural and beautiful clothing. As a new type of auxiliary material, lace fabric is widely used in the decoration of various clothing to make the clothing more gorgeous, especially in women's bras and underwear, which is more popular among young women. Lace fabric is a kind of fabric produced by a knitted jacquard machine. It has many types, such as lace lace, warp-knitted lace, elastic lace, non-elastic lac...
