The lint cleaning system is a modified jet-type lint cleaner that includes a supplemental air control vane. The supplemental air control vane (among other things) segregates discharged foreign materials from incoming supplemental air so that the incoming supplemental air is not contaminated by the discharged materials. The current system also enables a user to more effectively control the volume and the pathway of supplemental air entering the cleaner and thereby optimize the function of the air cleaner.

A method and system for the production of fibers for use in biocomposites is provided that includes the ability to use both retted and unretted straw, that keeps the molecular structure of the fibers intact by subjecting the fibers to minimal stress, that maximizes the fiber's aspect ratio, that maximizes the strength of the fibers, and that minimizes time and energy inputs, along with maintaining the fibers in good condition for bonding to the polymer(s) used with the fibers to form the biocomposite material. This consequently increases the functionality of the biocomposites produced (i.e. reinforcement, sound absorption, light weight, heat capacity, etc.), increasing their marketability. Additionally, as the disclosed method does not damage the fibers, oilseed flax straw, as well as all types of fibrous materials (i.e. fiber flax, banana, jute, industrial hemp, sisal, coir) etc., can be processed in bio composite materials.

The present disclosure discloses a method for producing raw cotton of machine-harvested long-staple cotton with a modal length of greater than or equal to 35 mm, including the steps: planting sea-island long-staple cotton and machining seed cotton, wherein planting the sea-island long-staple cotton includes preparation before machine harvesting, defoliation and ripening, choosing a cotton variety, etc.; and machining the seed cotton includes preparation before seed cotton ginning, mechanical separation of cotton seeds and raw cotton, and finishing the separated raw cotton. Raw cotton fibers obtained by the method of the present disclosure have main quality indexes that: a fiber length is 36.5-38.4 mm, a specific strength is 42.3-46.1 cN/tex, a uniformity is 86.2-87.0%, a foreign-fiber content is 0.2-0.4 g/t, and an impurity content is 2.6-3.4%. According to the method, not only can impurities and foreign fibers be effectively removed, but also mechanical damage to the raw cotton of the machine-harvested long-staple cotton with the modal length of greater than or equal to 35 mm is relatively small.

A method is for filling a fillable portion of a garment to be padded to obtain a padded garment, such as a garment or blanket. A cashmere fiber mass is fed towards a carding station. The cashmere fiber mass is mechanically opened and blended in the carding station by a carding machine to obtain a staple cashmere fiber. The staple cashmere fiber exiting from the carding station is fed towards a beating station. The staple cashmere fiber is cleaned in the beating station by cleaning air flow adapted to cross and inflate the staple cashmere fiber to remove residual impurities and dust from the staple cashmere fiber. The staple cashmere fiber exiting from the beating station is fed towards an injecting station and injected into the fillable portion by a pusher for introducing the staple cashmere fiber into the fillable portion to obtain the padded garment.

A method for preparing an insulating product based on wool includes an aeration step inside a device, the device including a chamber and at least one structure capable of generating a turbulent gaseous flow, during the aeration step. A stream of carrier gas is introduced into the chamber and a wool in the form of nodules or flakes is subjected to the turbulent flow of this carrier gas with entrainment in one sense in a direction A and in the opposite sense in a direction B that is the opposite to the direction A so that within the chamber there is at least in one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.
