Embodiment 1

[0038] 1) Use 2128B raw cotton, that is, white cotton grade 2, a length of 28 mm, and a grade B of the main micronaire value grade as raw materials.

[0039] 2) Open and remove impurities in the fiber pretreatment process. Specifically, after JWF1012 reciprocating plucking machine → AMP3000 metal Mars heavy object three-in-one detector → TF50 heavy object separator → JWF1102 single-axis flow cotton opener → FA028C-160 (10) multi-bin cotton mixing machine → JWF1124-160 open Cotton machine → foreign fiber sorting machine and other main devices can remove 80% of the large impurities such as dust, mud, iron wire, metal filings, different-colored silk, cotton stalks and cotton leaves in cotton fibers. Fiber handling capacity: 750kg / h.

[0040] 3) The pre-treated cotton fiber is transported to the ZW1208 carding machine by airflow for preliminary carding, and at the same time removes impurities with a particle size above 0.5mm. Then it is sent to W1092A-200 Dacang Cotton Blender f...

Embodiment 2

[0061] 1. Use 3129B raw cotton, that is, white cotton grade 3, with a length of 28 mm and a main micronaire value of grade B as raw material.

[0062] 2. Other steps are the same as Example 1.

Embodiment 3

[0064] 1. Use 2127B raw cotton, that is, white cotton grade 2, a length of 27 mm, and a grade B of the main micronaire value as raw materials.

[0065] 2. Other steps are the same as in Example 1.

Abstract

The invention relates to a natural cotton fiber spunlaced nonwoven fabric for medical health and a production method thereof. The method is performed according to the following steps: preprocessing fibers; preliminarily combing cotton fibers; performing fine mixing; performing fine combing; forming a fiber net and performing drafting; performing hydraulic entanglement on the fiber net to form a cotton fiber spunlaced nonwoven fabric, and squeezing a bleaching solution into the fabric; performing cold pad-batch; removing cotton wax and pectin substances through a one-step method; performing cloth cover modification or jacquard treatment on a jacquard spunlaced device; drying the cotton fiber spunlaced nonwoven fabric on a tentering and setting machine; cutting the natural cotton fiber spunlaced nonwoven fabric, packaging the cut cotton fiber spunlaced nonwoven fabric, and warehousing the packaged cotton fiber spunlaced nonwoven fabric. According to the natural cotton fiber spunlaced nonwoven fabric for medical health, the gram weight deviation of the unit area does not exceed the range of minus 7% to plus 7%, the whiteness is greater than and equal to 85, the water absorption time is smaller than or equal to 5 s, the pH value is 6-8, the water-soluble matters are less than or equal to 0.5%, the soluble matters in ether are less than or equal to 0.5%, and the surface active substances are smaller than or equal to 2 mm. The natural cotton fiber spunlaced nonwoven fabric for medical health, provided by the invention, has the advantages of good hand feeling, good moisture absorption, good air permeability and no irritation to skins, the nonwoven fabric can be naturally degraded after being used, and the nonwoven fabric completely meets the requirement of environmental protection. The nonwoven fabric can be widely applied to the fields of medical care, hygiene, cosmetology, daily life, industrial cleaning, clean rooms and the like.

Description

technical field [0001] The invention relates to a natural cotton fiber spunlace nonwoven fabric for medical hygiene and a production method thereof, belonging to the technical field of industrial textile nonwoven materials. Background technique [0002] The production process of similar products can refer to the production method of patent 200510033147.1 cotton non-woven medical dressing. The production method has the disadvantages of simple pre-treatment, high product impurities, long scouring and bleaching process, high energy consumption, low production efficiency, and the cloth surface of the product after scouring and bleaching is fluffy, soft, and the end surface is uneven. Lower phenomena, thus affecting the product quality and limiting the end use of the product. The present invention better solves the above problems by adding pre-combing, cold pad-batch, spunlace jacquard, tenter setting and drying, etc., so that the quality of natural cotton fiber spunlace nonwove...
