The invention provides a knitted functional fabric for wicking moisture away from the body of a user. The fabric comprises a technical face formed from a yarn; a technical back formed from a yarn; and a spacer formed from a yarn that connects the technical face to the technical back. The technical face and the technical back comprise a hydrophilic yarn.

Cellulose derivative-polyester composite fibers, matrices including such fibers, and methods for making and using such fibers and matrices are disclosed.

According to an example aspect of the present invention, there is provided a melt spinning method of cellulose based fibers with controlled molar masses and different side lengths, and continuous melt spun cellulose fibers thereof.

A fiber blend containing: (a) a cellulose acetate (CA) staple fibers having a denier per filament (DPF) of 3.0 or less; and (b) structural staple fibers having a dpf of 6.0 or more; and (c) optionally binder fibers. The fiber blend can be made into nonwoven webs for heat-bonding and subsequent use as thermal insulation in, e.g., outerwear, bedding, etc. The fiber blend can now contain sustainably derived fibers, optionally biodegradable, that provide good thermal insulation clo values and loft even after multiple wash cycles along with good short term compression recovery.

A method of making a pilling-resistant fabric is provided. In one instance, the method comprises (a) blending a cellulose acetate (CA) staple fiber with a non-CA staple fiber to form a blended yarn comprising 20 to 80 wt % of the CA staple fiber and (b) forming a pilling-resistant fabric comprising the blended yarn. In another instance, the method comprises (a) providing a first yarn comprising at least 20 wt % of a CA staple fiber and (b) forming a pilling-resistant fabric comprising the first yarn and a second yarn comprising a non-CA staple fiber. The CA staple fiber has (i) a round or closed-C cross-sectional shape, (ii) a cut length of 20 to 80 mm, (iii) a crimp frequency of 4 to 24 crimps per inch (CPI), and (iv) a denier per filament (DPF) of 0.5 to 4.0. The pilling-resistant fabric has a higher pilling resistance rating than a fabric made without the CA staple fiber.

This disclosure relates to air-assisted spinnerets and spinneret arrays for electrospinning. In some embodiments, the air-assisted spinnerets and spinneret arrays are incorporated in electrospinning systems and/or electrospinning machines. Methods of making and using the same are also described herein.

It is disclosed a method of producing a yarn having the look and feel of natural fibers, the method comprising the steps of preparing a first plurality of man-made textile fibers or a second plurality of natural textile fibers, the first and second plurality of textile fibers being obtained from breaking the first or the second textile fibers under the effect of a mechanical force applied to the first or the second textile fibers. A final blend for producing the yarn, can be prepared by adding the first plurality of textile fibers to a plurality of man-made fibers, or by adding the second plurality of textile fibers to a plurality of man-made fibers, or by adding the first plurality of textile fibers to the second plurality of textile fibers.

A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.

Disclosed are cellulose acetate tows, bales, and filter rods having from greater than 9 to less than 12.5 denier per filament and from 20,000 to 40,000 total denier, for use in smoking devices, including aerosol-generating devices such as an electrically heated cigarette.
