Embodiment Construction

[0021] Such as figure 1 As shown, the production process of cotton non-woven medical dressing includes the following steps:

[0022] 1) Raw material preparation: the raw cotton, that is, 100% pure natural, undegreased and bleached lint-free cotton, is prepared for use;

[0023] 2) Blowing: First, the raw cotton is removed by a cleaning machine, and the three threads and foreign objects in the raw cotton, such as cotton leaves, etc., are screened out. This step is a known technology and is the same as the prior art;

[0024] 3) Carding: It includes two parts: opening and carding. Opening means using a carding machine to open the raw cotton after cleaning to form a single fiber state, which is necessary for removing small impurities and carding. Carding is to use a carding machine to comb the single fiber, and comb it according to the longitudinal direction of the raw cotton fiber, so that the tension between the fibers can be maximized. At the same time, the small impurities ...

Abstract

This invention refers to no slub cloth produce method. That is a whole no slub cloth medicine dressing produce method. Its craftwork process order includes these steps: cleanliness- carding- spreading net-water stab-degrease- bleach- finished product crimp. This invention reduce contain mixed rate, advance finished product eligibility rate of whole working procedure, reduce the cost of produce, save the materials and energy and reduce contain mixed quantity. Make sure the finished product is healthful and reduce the contain bacterium rate. In his invention, the direct product texture is soft, the appetency with skin is good, innocuity, without simulate, without hypersusceptibility, good absorbing water, use convenience.

Description

【Technical field】 [0001] The invention relates to a production method of a pure natural nonwoven fabric, in particular to a production method of an all cotton natural nonwoven medical dressing. 【Background technique】 [0002] Medical dressings mainly include synthetic fiber non-woven fabrics and cotton non-woven fabrics. The composition of synthetic fiber non-woven fabrics is generally 70% viscose and 30% polyester (including petroleum synthetic raw materials). The raw material resources are non-renewable. Production The cost is high, the cost of destruction after use is high, and it is not environmentally friendly. At the same time, some users will be allergic to its materials during use, so synthetic fiber non-woven medical dressings are not widely used. Cotton non-woven medical dressings are widely used because their raw materials are natural cotton, sufficient raw materials, simple processing, soft, environmentally friendly, good water absorption, non-toxic, non-irritati...
