example 1

[0027] Example 1: The nonwoven fabric includes a fiber web, and 100% natural cotton fibers are pre-opened, mixed, finely opened, carded into a web, and finely entangled with high-pressure water needles. The non-woven fabric is composed of 100% cotton fibers. Due to the natural characteristics of cotton, the fineness and length are irregular and fluctuating compared with ordinary chemical fibers. The difficulty of carding and high-pressure water needle entanglement in the production process is more difficult than that of ordinary chemical fibers. High in fiber. The thickness of the pure cotton nonwoven fabric ranges from 0.3 to 1.5mm, and the weight is 25-50g / m 2 .

[0028] The preparation steps of pure cotton perforated spunlaced nonwoven fabric: put the whole package of cotton fibers in the raw material buffer room in advance, which is close to the production environment, which is beneficial to the subsequent processing. The continuous production process of pure cotton spun...

Abstract

The invention discloses a novel pure cotton punched non-woven fabric and a preparation method and application thereof. The non-woven fabric is composed of 100% cotton fiber materials, the gram weight ranges from 25 g / m<2> to 50 g / m<2>, and the thickness of the non-woven fabric ranges from 0.3 mm to 1.5 mm. The preparation method comprises the steps that after the 100% cotton fiber materials are subjected to sufficient opening, impurity removing and carding for web formation through spunlace nonwoven processing equipment, high pressure water needle tangling and reinforcement are executed, a wet non-woven fabric is dried through a drum type drying device, and the pure cotton non-woven fabric is obtained. The non-woven fabric is suitable for the surfaces of personal hygiene products, the fabric has the advantages of being good in skin-friendly property, soft in hand feeling, small in wetback amount and the like, and punching can be conducted on the non-woven fabric for different patterns.

Description

technical field [0001] The invention relates to a nonwoven fabric, its preparation method and application, more specifically, the invention relates to a pure cotton perforated nonwoven fabric, its preparation method and application, and belongs to the technical field of weaving. Background technique [0002] The spunlace non-woven process is a non-woven fabric manufacturing process that sprays the fiber web with high-pressure, high-speed, fine water, and at the same time entangles the fibers through the double action of the trawl water column reflection, so that the fiber web can be reinforced and have a certain strength. [0003] Spunlace nonwovens are characterized by a wide source of raw materials and a wide range of uses. The product has high hygroscopicity and air permeability, soft hand feeling, physical entanglement between fibers without chemical adhesives, suitable for skin application, and the surface layer of women's hygiene products and baby diapers will be safer...
