Embodiment 1

[0022] The purpose of the present invention is to design a dyeing and finishing process of all-cotton knitted cloth for military products with simple operation, environmental protection, good color fastness, good dry and wet rubbing fastness, and good bursting strength of gray cloth. The technical scheme of the present invention is as follows Achieved:

[0023] For the dyeing and finishing process of cotton knitted fabric, the gray fabric is 50S / 1 cotton double-sided fabric, which requires a width of 140cm to be effective and a weight of 185g / m 2 .Dry friction level 4, wet friction level 3, soaping fastness level 4, strength over 500N, specifically include the following steps:

[0024] a) Selection of gray fabric: select 50S Xinjiang combed long-staple cotton yarn, and select all-cotton double-sided fabric woven by Taiwan double-sided large circular machine;

[0025] b) Singeing: Singeing on both sides by German Ostov knitting singeing machine;

[0026] c) Pretreatment: scou...

Abstract

The invention discloses a dyeing and finishing process for an all-cotton knitted product suitable for special purposes. The process comprises the following steps: 1) grey cloth selection; 50S Xinjiang combed long staple cotton yarns are selected to be woven all-cotton double-side cloth by a selected Taiwan double-side circular knitting machine; 2) singeing: an Osthoff knitting and singeing machine is adopted to realize double-side singeing; 3) pretreatment: boiling-off of the cloth is carried out with a 745 chelating dispersant, a multifunctional refining agent, a 705 oil removal agent, a hydrogen peroxide stabilizer, caustic soda flack and hydrogen peroxide; 4) mercerizing: steps of using an unstressing scutching knitting mercerizing machine of a domestic self-developed Jiangsu Hongqi screen printing machine to realize mercerization and the like are carried out. According to the process, not only are all indexes required by military products met, but also the ventilation and heat dissipation, and moisture absorption and sweat releasing are improved, the wet rubbing fastness and burst strength are increased, product styles of conventional all-cotton knitted cloth are improved, and the market of the all-cotton knitted products is extended and expanded, so that the process has very strong market competitiveness.

Description

【Technical field】 [0001] The invention relates to the technical field of printing and dyeing of knitted fabrics, in particular to the technical field of the pretreatment dyeing and finishing process of cotton knitted fabrics suitable for military special purposes. 【Background technique】 [0002] With the improvement of people's living standards and the continuous improvement and popularization of printing and dyeing technology, the products of enterprises are becoming more and more similar, and the competition is becoming more and more fierce. Consumers' indicators for knitted fabric products are also getting higher and higher. , especially fabrics for military products. Conventional military products generally have the disadvantages of poor moisture absorption and perspiration and airtightness; in addition, conventional cotton knitted military products fully embody the advantages of moisture absorption and perspiration, but to some extent they cannot meet the color fastness...
