The Products Of Hydrophilic Nonwovens Are Widely Used.

　　 nonwovens The applications of clothing, indoor products, medical treatment, hygiene, health care products and industrial products are increasing. The products of hydrophilic nonwovens are also widely used in these fields, and will surely develop at high speed in the field of high-end industry.

For example, many compressed Spunlaced towels made of water Spunlaced cloth produced by many Spunlaced factories can instantly absorb water, expand water and expand them into wet towels in a short time, and make them more convenient to use.

Correspondingly, hydrophilic properties and testing means, such as instantaneous water absorption, water absorption uniformity, water retention rate, moisture retention, water conductivity and moisture permeability, will also become an indicator of evaluating the performance index or technical content of hydrophilic nonwovens.

In the long run, China should speed up the development of all kinds of special function fibers, including super absorbent fiber and super absorbent fiber, and improve the existing hydrophilic finishing methods to meet the needs of international development and people's needs, so that the application of hydrophilic nonwovens will be more extensive and universal.

The hydrophilic properties of fiber include Hygroscopicity and Water absorbency Two aspects, so the hydrophilic mechanism of fiber also involves two aspects: moisture absorption and water absorption. Moisture absorption, water absorption and even high absorbent nonwovens as disposable goods have the economic and performance advantages that traditional textiles can not match.

For spunbonded nonwovens, polypropylene, which is used as raw material, has a non-polar structure with high crystallinity and no hydrophilic groups. Therefore, the moisture absorption of spunbonded nonwovens is poor. When used as hygienic materials, it must be tidied up to improve its hygroscopicity.

One way to give different kinds of nonwovens functionality in hydrophilic finishing is a way to develop new products and meet the functional requirements of the market.
