Polylactic acid fiber shorts and applications

1.About polylactic acid short fiber

Polylactic acid (PLA) staple fiber is a biobased and biodegradable fiber made from renewable resources such as corn starch. Due to its environmentally friendly properties and diverse application potential, PLA short fiber has been promoted and applied in many fields

2. Classification of polylactic acid short fiber

Staple fibers are mainly divided into three categories according to different uses: spinning, filling, and non-woven. Spinning and thread making is the main use of short fiber. Filling is mainly short fiber in the form of filler, which is used as filling material for home decoration and thermal insulation materials for clothing, such as bedding, cotton clothing, sofa furniture, plush toys, etc. Nonwovens are an extension of the use of short fibers and have developed rapidly in recent years. Nonwovens are widely used. For example, spunlace nonwovens are mainly used in wet wipes, medical and other fields; needlepunched nonwovens can be used in related engineering fields such as geotextiles, leather base fabrics, and linoleum base fabrics; in addition, hot-rolled Hot air non-woven fabrics are used in packaging, sanitary materials and other fields.

Polylactic acid short fiber: fineness: 0.9-6D, length: 3/6/12mm, product application: wet papermaking, flocking, etc.Polylactic acid single-component short fiber: fineness: 1-6D, length: 6-64mm, product applications: yarn, non-woven fabrics, etc.

Polylactic acid bicomponent short fiber: fineness: 1.5-5D, length: 6-64mm, product applications: non-woven fabrics, thermal bonding, fillers, etc.

Polylactic acid three-dimensional curly short fiber: fineness: 1.5-5D, length: 38/51/64mm, product application: filling of clothing, home textiles and toys, etc.

4. Application of polylactic acid short fiber

① Clothing fabrics: Pure or blended, blended with various other fibers such as cotton, linen, silk, wool, viscose, lyocell, etc., to produce different styles of clothing fabrics.

② Disposable hygiene, medical supplies and packaging materials, etc.Polylactic acid staple fiber can also be widely used in the field of packaging and disposable consumer products such as sanitary materials, especially sanitary materials (such as diaper pads, diapers, sanitary napkins, etc.).

③ Filling of quilts, cotton-padded jackets and toys: represented by three-dimensional curly polylactic acid short fiber, which can be pure PLA or mixed with other fibers to replace existing polyester-related fillings.In general, polylactic acid fiber, as a new type of environmentally friendly material, has huge development potential in many industries and fields such as textiles, industry and agriculture, and sanitary materials.
